With the demand of the development of the 5G (the 5th Generation, fifth Generation (communication technology)) technology, the wireless charging function of the smart phone is gradually popularized, and since the traditional metal housing affects the transmission of signals, glass housings which contribute to the improvement of signals are increasingly popular, and more mobile phones adopt backshells made of glass. In the decoration technology of the rear cover of the glass of the mobile phone, etching AG (Anti-glare glass) is one of the hot trends.

Glare is a poor lighting phenomenon, and occurs when the brightness of a light source is extremely high or the difference between the brightness of the background and the brightness of the center of the field of view is large. The anti-glare glass is also called low-reflection glass, can effectively reduce the glare effect, and enables people to see objects clearly in the sun.

In some related technologies, the whole surface of the mobile phone glass rear shell has an anti-glare effect, and the displayed visual effect is single. Or, a part of the surface of the mobile phone glass rear shell is a bright surface, and a part of the surface has an anti-glare effect, namely, the rear shell integrally presents a local anti-glare effect, an obvious boundary exists between an area with the anti-glare effect and the bright surface area, and the transition is sudden, so that the visual effect is poor, the hand feeling transition is not smooth, and the touch experience of a user is poor.

In order to solve the problems, the application provides a shell with a gradually-changed anti-dazzle effect for terminal equipment, so that the visual effect and the touch experience of the shell are improved.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, the present application provides a housing for a terminal device, the housing comprising a housing substrate, the housing substrate comprising a first surface; the shell also comprises an anti-dazzle microstructure arranged on the first surface of the shell base material, and the anti-dazzle effect formed by the anti-dazzle microstructure is gradually enhanced in a set area of the first surface along a set direction parallel to the first surface.

In the above embodiments of the application, because the anti-glare effect formed by the anti-glare microstructures is gradually enhanced in the set region of the first surface along the set direction parallel to the first surface of the housing substrate, the gradually-changed anti-glare effect in the set region of the housing surface is more natural, a better visual effect is formed, the hand feeling is smoother, and better tactile experience is achieved.

With reference to the first aspect, in a first possible implementation manner, the setting region includes a plurality of sub-regions arranged side by side along a setting direction, and sizes of the plurality of sub-regions along the setting direction are equal; at least one part of each sub-area is provided with an anti-dazzle microstructure; in the set direction, the areas of the regions provided with the anti-glare microstructures in the plurality of sub-regions are sequentially increased.

In the above embodiment, the areas of the regions of the plurality of sub-regions where the anti-glare effect is formed are sequentially increased along the set direction, so that the anti-glare effect formed by the anti-glare microstructures along the set direction is gradually increased within the set region of the first surface. Thereby the anti-dazzle effect of nature gradual change is formed on the casing surface, and visual effect and touch experience are all better.

With reference to the first possible implementation manner of the first aspect, in a second possible implementation manner, an orthographic projection of the anti-glare microstructure disposed in the set area on the plane determined by the first surface includes a plurality of projection patterns, and each sub-area of the set area corresponds to the plurality of projection patterns; along the set direction, the area of one of the plurality of projection patterns corresponding to different subregions gradually increases.

And the regions corresponding to the plurality of projection patterns on the set region form regions with anti-dazzle effect, so that the visual and tactile effects on the surface of the shell are better.

With reference to the second possible implementation manner of the first aspect, in a third possible implementation manner, the plurality of projection patterns corresponding to each sub-region of the setting region are uniformly arranged, and the areas of the plurality of projection patterns in the same sub-region are equal. The multiple pores corresponding to each sub-region of the set region are uniformly arranged, and the multiple pores in the same sub-region have the same area. Therefore, on the surface of the shell, along the set direction, the set region integrally shows the gradually enhanced anti-dazzle effect, and the anti-dazzle microstructure of the set region on the surface of the shell shows the regularly changed anti-dazzle effect, so that the visual effect and the tactile effect are further improved.

With reference to the second possible implementation manner of the first aspect, in a fourth possible implementation manner, the shape of the projection pattern includes any one or more of a circle, an ellipse, a straight-sided rectangle, an arc-sided rectangle, a straight-sided triangle, and an arc-sided triangle. The shape of the aperture includes any one or more of a circle, an ellipse, a straight-sided rectangle, an arc-sided rectangle, a straight-sided triangle, and an arc-sided triangle.

With reference to the sixth possible implementation manner of the first aspect, in a seventh possible implementation manner, the plurality of projection patterns are zigzag in shape. Therefore, the anti-glare effect is gradually enhanced along the set direction on the set area on the surface of the shell, and the pattern of the area with the anti-glare effect is saw-toothed, so that the visual effect is better.

With reference to the first aspect, in an eighth possible implementation manner, along the set direction, the haze of the set area of the first surface gradually increases, and at least one of the transmittance and the glossiness of the set area of the first surface gradually decreases.

With reference to the eighth possible implementation manner of the first aspect, in a twelfth possible implementation manner, the gradient of change in any one of the haze, the transmittance, and the glossiness of the set area of the first surface along the set direction is 0.05% to 20%. Therefore, the gradual change degree of the anti-dazzle effect has a proper range, so that the gradual change anti-dazzle effect presented by the whole surface of the shell is more natural.

With reference to the first aspect, in a thirteenth possible implementation manner, the setting direction is parallel to a set of opposite sides of the first surface; or, the set direction is parallel to a diagonal of the first surface; or, the set direction is parallel to a line direction extending from one side to the other side of the pair of sides of the first surface and not parallel to the sides of the first surface.

Detailed Description

The embodiment of the present application provides a shell for a terminal device and a manufacturing method thereof, where the shell for a terminal device and the manufacturing method thereof may be applied to any terminal such as a mobile phone, a wearable device, a tablet computer, a notebook computer, a UMPC (ultra mobile personal computer), a netbook, and a PDA (personal digital assistant).

In some embodiments of the present application, the terminal device may be a mobile phone, and the structure of the terminal device applied to the embodiments of the present application is exemplarily described below by taking the mobile phone as an example.

As shown in fig. 1, 2 and 3, the mobile phone 100 includes a front case 1a disposed on a front surface (i.e., a surface for displaying) of the mobile phone 100, and a rear case 1b disposed on a rear surface (i.e., a surface opposite to the front surface) of the mobile phone 100, wherein the front case 1a and the rear case 1b are both made of glass.

In the decoration technology of the mobile phone glass rear shell 1b, AG is etched to effectively reduce the glare effect. In the related art, the anti-glare effect of the prepared mobile phone glass rear case 1b is as shown in fig. 2 and 3, and the whole anti-glare effect or the local anti-glare effect is exhibited. As shown in fig. 2, the whole surface of the rear housing 1b is an anti-glare region 1b-2, which shows an anti-glare effect on the whole surface, and the visual effect is relatively single, and as shown in fig. 3, the surface of the rear housing 1b includes a bright surface region 1b-1 and an anti-glare region 1b-2, which shows a local anti-glare effect, and an obvious boundary exists between the bright surface region 1b-1 and the anti-glare region 1b-2, and the transition from the bright surface region 1b-1 to the anti-glare region 1b-2 is sudden, so that the visual effect is poor, the hand feeling is not smooth, and the tactile experience is poor.

Based on the above situation, some embodiments of the present application provide a housing 2 for a terminal device, as shown in fig. 4a and 4b, fig. 5a to 5i, and fig. 7, the housing 2 includes a housing base material 21 and an anti-glare microstructure 22.

Among them, in some embodiments, the housing base material 21 is a base material such as a glass substrate. As shown in fig. 4a and 4b, the housing substrate 21 includes first and second opposing surfaces 21-a and 21-b.

The anti-glare microstructures 22 are disposed on the first surface 21-a of the housing base material 21, and along a setting direction AB parallel to the first surface 21-a of the housing base material 21, in a setting area G of the first surface 21-a, anti-glare effects formed by the anti-glare microstructures 22 are gradually enhanced.

Note that, in some embodiments, the anti-glare microstructures 22 are microstructures formed by a plurality of minute pits. The plurality of minute recesses are formed by performing a frosting process or a sandblasting process and then a polishing process on the first surface 21-a of the case base 21. Specifically, the first surface 21-a of the case base material 21 is subjected to a sandblasting or frosting step to roughen the first surface 21-a to form a plurality of recesses, thereby making the set region G of the first surface 21-a uneven, increasing the haze, decreasing the transmittance, and exhibiting the frosting effect. Then, the first surface 21-a exhibiting the frosted effect is polished to reduce the unevenness of the set region G of the first surface 21-a, so that the surface becomes round, the haze is properly reduced, the transmittance is improved, and the anti-glare microstructure 22, which is a plurality of tiny pits as described above, is formed, and diffuse reflection occurs when light is irradiated onto the anti-glare microstructure 22, thereby generating the anti-glare effect.

In addition, the "set area G" mentioned above refers to at least a part of the area on the first surface 21-a of the case base material 21, and the set area G is an area where a gradual anti-glare effect is required to be formed on the first surface 21-a.

The defined area G may be the whole area of the first surface 21-a, see the housing 2 shown in fig. 4a and 7, in which case the whole surface of the housing exhibits a gradual glare-proof effect.

The defined area G may be a part of the area of the first surface 21-a, see fig. 4b and fig. 5a to 5i for the housing 2, in which case the housing surface locally exhibits a gradual anti-glare effect.

For example, referring again to FIG. 4b, along the set direction AB of the first surface 21-a, the first surface 21-a is divided into three regions: in turn, a first region A₁A second region A₂And a third zoneDomain A₃The setting region G is a region at the middle position among the three regions, i.e., a second region A₂So that the middle region of the surface of the case exhibits a gradual anti-glare effect. In this case, the first area A of the first surface 21-a₁Set as a bright surface and in a third area A of the first surface 21-a₃The anti-dazzle micro-structure 22 is arranged on the surface of the shell from the first area A₁The bright surface effect of (a) is transited to the third area A through the gradually enhanced anti-glare effect of the set area G₃The anti-dazzle effect of the LED lamp realizes natural transition. The anti-glare effect of the design can be seen in 5a to 5 i.

In the above embodiment of the application, along the setting direction AB parallel to the first surface 21-a of the housing base material 21, in the setting area G of the first surface 21-a, the anti-glare effect formed by the anti-glare microstructures 22 is gradually enhanced, and the setting area G of the housing surface has a more natural anti-glare effect, which forms a better visual effect, and the hand feeling is smoother, thereby having better tactile experience.

In some embodiments, as shown in fig. 5a to 5c, the set area G of the first surface 21-a of the housing base material 21 includes a plurality of sub-areas G side by side along the set direction AB₁And the plurality of sub-regions G₁Is equal in size along the set direction AB, each sub-area G₁Is provided with anti-glare microstructures 22. Along a set direction AB, the plurality of sub-regions G₁The area of the region in which the anti-glare microstructures 22 are disposed increases in sequence.

In the above embodiment, as shown in fig. 5a, the setting region G is equally divided into a plurality of sub-regions G along the setting direction AB₁The area between two adjacent dotted lines in the figure is a sub-area G₁Said plurality of sub-regions G₁Are equal in size along the set direction AB and are all x. In each sub-region G₁In the method, at least one part of the region is provided with the anti-glare microstructures 22, so that the region provided with the anti-glare microstructures 22 forms an anti-glare effect, and the other part of the region is not provided with the anti-glare microstructures, so that the region not provided with the anti-glare microstructures is shapedThe effect of bright surface is achieved.

Along a set direction AB, the plurality of sub-regions G₁The areas of the regions in which the anti-glare microstructures 22 are disposed are sequentially increased such that the plurality of sub-regions G are arranged along the set direction AB₁The areas of the regions of the first surface 21-a where the anti-glare effect is formed are sequentially increased, so that the anti-glare effect formed by the anti-glare microstructures 22 along the set direction AB is gradually increased in the set region G of the first surface 21-a. Thereby the anti-dazzle effect of nature gradual change is formed on the casing surface, and visual effect and touch experience are all better.

In some embodiments, as shown in fig. 5a to 5c, the design of the anti-glare microstructures 22 disposed in the setting region G may adopt the first design and/or the second design.

When the shell is prepared, in the process of forming the anti-glare microstructures 22, the shape of the projection pattern 31 included in the orthographic projection 3 of the anti-glare microstructures 22 on the plane determined by the first surface 21-a can be determined according to actual needs, so that the surface of the shell presents various visual effects.

Illustratively, as shown in fig. 5b, the orthographic projection 3 of the anti-glare microstructures 22 disposed in the set area G on the plane defined by the first surface 21-a has a plurality of pores 32, and each sub-area G of the set area G₁Corresponding to the plurality of apertures 32. Along a set direction AB, different sub-regions G₁The area of the corresponding one of the plurality of apertures 32 gradually decreases.

The orthographic projection 3 of the anti-glare microstructure 22 on the plane defined by the first surface 21 has a plurality of apertures 32, illustrated in each sub-region G₁The regions corresponding to the plurality of pores 32 are not provided with the anti-glare microstructures 22 to form a bright surface effect, and each subregion G is provided with a plurality of anti-glare microstructures₁Except for the regions corresponding to the plurality of pores 32, is provided with an anti-glare structure, forming an anti-glare effect.

Thus, in the setting region G of the first surface 21, the plurality of sub-regions G are arranged along the setting direction AB₁The areas of the regions with the bright surface effect are sequentially reduced, the areas of the regions with the anti-glare effect are sequentially increased, and the set region G integrally shows the gradually enhanced anti-glare effect. Moreover, the area corresponding to the plurality of apertures 32 on the set area G of the first surface 21 constitutes an area with a bright surface effect, so that the visual and tactile effects of the surface of the housing are good.

Further, as a possible design, please refer to fig. 5b again, each sub-area G of the area G is set₁The plurality of pores 32 corresponding to the domains are uniformly arranged and are positioned in the same sub-region G₁The plurality of apertures 32 are equal in area. Thus, on the first surface 21-a of the housing base material 21, each of the sub-areas G in the set area G₁The regions except the regions corresponding to the plurality of holes 32 are provided with the uniformly arranged anti-glare microstructures 22, and the set region G integrally shows a gradually enhanced anti-glare effect along the set direction AB on the surface of the shell. Moreover, the anti-glare microstructures 22 in the set region G on the surface of the housing exhibit regularly changing anti-glare effects, which further improves the visual and tactile effects.

In addition, as a possible design, as shown in fig. 8, the shape of the aperture 32 includes any one or more of a circle, an ellipse, a straight rectangle, an arc rectangle, a straight triangle, an arc triangle, etc., and the present embodiment does not limit the shape of the aperture to have various alternative figures, and the shape of the aperture 32 shown in fig. 5b is a circle. In the process of forming the anti-glare microstructures 22 during the preparation of the housing, the shape of the pores 32 included in the orthographic projection 3 of the anti-glare microstructures 22 on the plane defined by the first surface 21-a can be determined according to actual needs, so that the surface of the housing presents a variety of visual effects.

Illustratively, as shown in FIG. 5c, in a first region G-1 of the set region G along the set direction AB, the orthographic projection 3 of the anti-glare microstructures 22 on the plane defined by the first surface 21-a includes a plurality of projection patterns 31, and each of the subregions G is defined by a first surface 21-a₁Corresponding to a plurality of projected patterns 31. Along a set direction AB, different sub-regions G₁The area of one of the corresponding plurality of projection patterns 31 gradually increases; in a second area G-2 of the set area G, the orthographic projection 3 of the anti-glare microstructure 22 on the plane defined by the first surface 21-a has a plurality of pores 32, and each sub-area G of the set area G₁Corresponding to the plurality of apertures 32. Along a set direction AB, different sub-regions G₁The area of the corresponding one of the plurality of apertures 32 gradually decreases.

In a first region G-1 of the set region, each sub-region G₁An anti-glare microstructure 22 is disposed in a region corresponding to the plurality of projection patterns 31 to exhibit an anti-glare effect, and each of the sub-regions G is disposed in a second region G-2 of the set region G₁The regions corresponding to the plurality of pores 32 are not provided with the anti-glare microstructures 22, resulting in a bright surface effect.

So that a plurality of sub-areas G are arranged along a set direction AB in a set area G on the surface of the shell₁The areas of the regions with the anti-glare effect are sequentially increased, and the set region G integrally shows the gradually enhanced anti-glare effect. Moreover, the regions corresponding to the plurality of projection patterns 31 on the set region G of the first surface 21-a constitute regions having an anti-glare effect, and the regions corresponding to the plurality of apertures 32 constitute regions having a bright surface effect, so that the visual and tactile effects of the surface of the housing are good.

Further, as a possibilityReferring again to FIG. 5c, in the first region G-1 of the set region G, each sub-region G₁The corresponding projection patterns 31 are uniformly arranged and are positioned in the same sub-region G₁Has the same area, and each of the sub-regions G is arranged in a second region G-2 of the set region G₁The corresponding holes 32 are uniformly arranged and are positioned in the same sub-area G₁The plurality of apertures 32 are equal in area. Like this, on the casing surface, along setting for direction AB, set for regional G whole to present the anti-dazzle effect of gradual enhancement to, the anti-dazzle micro-structure 22 of the regional G of setting for on casing surface presents the anti-dazzle effect of regular change, has further promoted vision and touch effect.

Further, as a possible design, as shown in fig. 8, the shape of the projection pattern 31 or the shape of the aperture 32 includes any one or more of a circle, an ellipse, a straight-sided rectangle, an arc-sided rectangle, a straight-sided triangle, and an arc-sided triangle, and the present embodiment is not limited thereto. There are many alternative patterns for the shape of the projected pattern 31 or the shape of the aperture 32, and the projected pattern 31 is shown in fig. 5c as being circular and the aperture 32 as being rectangular with curved sides. In the process of forming the anti-glare microstructures 22 when preparing the shell, the shape of the projection pattern 31 and the shape of the pores 32 included in the orthographic projection 3 of the anti-glare microstructures 22 on the plane defined by the first surface 21-a can be determined according to actual needs, so that the surface of the shell presents a variety of visual effects.

It should be noted that the projection pattern 31 or the pattern of the pores 32 included in the orthographic projection 3 of the anti-glare microstructure 22 of the housing shown in fig. 5a to 5c on the plane defined by the first surface 21-a is only an illustration, and in the actual housing surface, the size of each projection pattern or pore is small, that is, the size of the anti-glare microstructure is small, so that the housing surface presents a naturally graded anti-glare effect.

In some embodiments, a plurality of sub-regions G of the region G are set along the setting direction AB₁Of a sub-region G₁The area of the region in which the anti-glare microstructures 22 are disposed occupies the sub-region G₁Area ratio ofExamples vary from 0% to 100%, inclusive.

That is, in the above-described embodiment, the plurality of sub-regions G are along the set direction AB₁First sub-region G of₁The area of the region in which the anti-glare microstructures 22 are disposed occupies the sub-region G₁Is close to 0%, the plurality of sub-regions G₁Of the last sub-region G₁The area of the region in which the anti-glare microstructures 22 are disposed occupies the sub-region G₁The proportion of the area of (a) is close to 100%.

Thus, the antiglare effect exhibited by the set region G of the housing surface is: along a set direction AB, the plurality of sub-regions G₁Each sub-region G of₁The area of the region with the anti-dazzle effect is sequentially increased to 100% from 0%, the area of the region with the anti-dazzle effect is gradually increased, the anti-dazzle effect is gradually enhanced, the anti-dazzle effect displayed on the surface of the shell is more natural in transition, and the visual sense effect and the touch sense effect are better.

In some embodiments, as shown in fig. 5d to 5i, the orthographic projection 3 of the anti-glare microstructures 22 disposed in the set area G on the plane defined by the first surface 21-a includes a plurality of projection patterns 31, the plurality of projection patterns 31 being arranged side by side along a direction perpendicular to the set direction AB; and along the setting direction AB, the size of each projection pattern 31 along a direction perpendicular to the setting direction AB gradually increases.

In the above-described embodiment, along the setting direction AB, the size of each projection pattern 31 in the direction perpendicular to the setting direction AB gradually increases. Illustratively, the setting direction AB shown in fig. 5d is parallel to the long side of the first surface 21-a, and the direction perpendicular to the setting direction AB is parallel to the short side of the first surface 21-a, and the plurality of projection patterns 31 are arranged side by side in the direction parallel to the short side of the first surface 21-a. The dimension of each projection pattern 31 in the direction perpendicular to the setting direction AB gradually increases along the setting direction AB, for example, in fig. 5d, in one of the projection patterns 31, the dimension b along the setting direction AB₁Less than dimension b₂。

In this way, the plurality of projection patterns 31 divide the set region G of the first surface 21-a into a plurality of regions having the anti-glare effect and a plurality of regions of the bright surface, the two regions alternately appear, the plurality of regions having the anti-glare effect are arranged side by side in a direction perpendicular to the set direction AB, and along the set direction AB, the size of each of the plurality of regions having the anti-glare effect in the direction perpendicular to the set direction AB gradually increases, so that the area of the region having the anti-glare effect of the set region G gradually increases along the set direction AB on the surface of the housing, a gradually increased anti-glare effect is formed, and the gradation effect is more natural.

Also, it can be understood that the greater the number of the plurality of projection patterns 32, the more frequently the plurality of regions having the anti-glare effect and the plurality of regions of the bright face of the set region G are alternately present, i.e., the greater the number of the aforementioned two regions, so that the less distinct the boundary between the two regions in the set region G is at the surface of the case, the more natural the gradual anti-glare effect is exhibited.

As a possible design, the plurality of projection patterns 31 are saw-toothed in shape. The saw teeth can be deformed in various ways, and the tail ends of the saw teeth can be in a sharper shape or a smoother shape; the contour line of the sawtooth can be a straight line or a curve; the saw teeth can be in an axisymmetric pattern or a non-axisymmetric pattern; and so on.

Illustratively, as shown in fig. 5d, the plurality of projected patterns 31 have a first sawtooth shape, the first sawtooth pattern includes a plurality of small teeth, each projected pattern 31 has a small tooth shape, and each projected pattern 31 has a shape that presents a contour line of the small tooth shape and a tip end. The size of each small tooth in the direction perpendicular to the set direction AB gradually increases from 0 in the set direction AB from the tip to the root end of the small tooth, so that the size of each projection pattern 31 in the direction perpendicular to the set direction AB gradually increases. Furthermore, on the set region G on the surface of the shell, along the set direction AB, the size of each small tooth in the direction perpendicular to the set direction AB of the region with the anti-dazzle effect is gradually increased, and the anti-dazzle effect gradually enhanced is presented.

Illustratively, as shown in fig. 5e, the plurality of projected patterns 31 are in a second sawtooth shape, the second sawtooth pattern includes a plurality of deformed small teeth, each projected pattern 31 is in a shape of a pointed deformed small tooth, and each projected pattern 31 has a shape that presents a deformed small tooth shape with a curved line on the contour line and a pointed end. The dimension of each small tooth in the direction perpendicular to the setting direction AB gradually increases from 0 in the setting direction AB from the tip to the root end of the small tooth, so that the dimension of each projection pattern 31 in the direction perpendicular to the setting direction AB gradually increases. Furthermore, on the set region G of the surface of the shell, along the set direction AB, the size of each deformed small tooth included in the region with the anti-dazzle effect along the direction perpendicular to the set direction AB is gradually increased, and the anti-dazzle effect gradually enhanced is presented.

Illustratively, as shown in fig. 5f, the plurality of projection patterns 31 have a third saw-tooth shape, the third saw-tooth shape includes a plurality of rounded teeth, the whole of the third saw-tooth shape is wavy, each projection pattern 31 has a shape of one rounded tooth, and each projection pattern 31 has a shape of rounded teeth with a curved line at the contour and rounded ends. The size of each small tooth in the direction perpendicular to the setting direction AB gradually increases from the tip to the root of the small tooth in the setting direction AB, so that the size of each projection pattern 31 in the direction perpendicular to the setting direction AB gradually increases. Furthermore, on the set region G on the surface of the shell, along the set direction AB, the size of each small smoothly deformed tooth included in the region with the anti-dazzle effect along the direction perpendicular to the set direction AB is gradually increased, and the anti-dazzle effect is gradually enhanced.

In some embodiments, the haze of the set area G of the first surface 21-a gradually increases and the at least one of the transmittance and the gloss of the set area G of the first surface 21-a gradually decreases along the set direction.

In the case described above, the parameters for characterizing the anti-glare effect of the first surface 21-a of the case substrate 21 include haze, transmittance, and glossiness. The larger the haze is, the stronger the anti-glare effect is, and the smaller the transmittance and the glossiness are, the stronger the anti-glare effect is. The set area G of the first surface 21-a has a gradually increasing haze and a gradually decreasing at least one of transmittance and gloss along the set direction AB of the first surface 21-a. Therefore, the effect that above-mentioned casing surface appears is, along setting for direction AB, and the anti-dazzle effect of the setting for region G on casing surface strengthens gradually, and the whole transition is more natural, and the feel is more smooth, and visual effect and sense of touch experience preferred.

In some embodiments, the haze of the set area G of the first surface 21-a varies from 0.1% to 98% along the set direction AB. Illustratively, the haze of the set area G of the first surface 21-a varies from 1% to 80%. Along the set direction AB, the haze of the first surface 21-a gradually increases from 0.1% to 98%, so that the anti-glare effect of the surface of the housing gradually increases, and a gradual anti-glare effect is presented.

In some embodiments, the transmittance of the defined area G of the first surface 21-a along the defined direction AB varies from 92% to 5%. Illustratively, the transmittance of the defined area G of the first surface 21-a varies from 92% to 10%. Along the set direction AB, the transmittance of the first surface 21-a is gradually reduced from 92% to 5%, so that the anti-glare effect of the surface of the shell is gradually enhanced, and a gradual anti-glare effect is presented.

In some embodiments, the gloss level of the defined area G of the first surface 21-a varies from 98GU to 1GU along the defined direction AB. Illustratively, the range of the gloss of the set area G of the first surface 21-a is varied from 98GU to 10 GU. Along the set direction AB, the transmittance of the first surface 21-a is gradually reduced from 98GU to 1GU, so that the anti-glare effect of the surface of the shell is gradually enhanced, and a gradually changed anti-glare effect is presented.

In some embodiments, the gradient of the change in any one of the haze, the transmittance and the glossiness of the set area G of the first surface 21-a along the set direction AB of the first surface 21-a of the housing base material 21 may reflect the degree of the gradual change of the anti-glare effect of the first surface 21-a along the set direction AB, and the greater the gradient of the change, the faster the change, representing the faster the speed of the anti-glare effect transitioning from weak to strong; the smaller the gradient of the change is, the slower the change is, which means that the speed of the anti-glare effect is slower from weak to strong, so that the transition is more natural and the hand feeling is smoother.

The degree of the gradual change of the anti-glare effect of the first surface 21-a may be limited to a suitable range according to the magnitude of the gradient of the change in any one of the haze, transmittance, and glossiness of the first surface 21-a, so that the gradual anti-glare effect exhibited by the surface of the case is more natural.

In some embodiments, the gradient of change in any one of haze, transmittance, and gloss of the set area G of the first surface 21-a along the set direction AB is from 0.05% to 20%. The value can be set within the above range in combination with the actual requirement for the anti-glare effect, and the variation gradient of any one of the haze, the transmittance, and the glossiness of the set region of the first surface 21-a is set, so as to obtain the anti-glare effect meeting the requirement. Illustratively, the set area G of the first surface 21-a has a gradient of variation in any one of haze, transmittance, and gloss of 0.4% to 8%.

It should be noted that, in the embodiment of the present application, the setting direction AB may be designed according to the actual requirement of the gradual change direction of the anti-glare effect, and the embodiment of the present application does not limit this.

As a possible design, the direction AB is set parallel to a set of opposite sides of the first surface 21-a. For example, as shown in fig. 5d to 5f, the set direction AB is parallel to one set of long sides of a set pair of sides of the first surface 21-a, and the size of each projection pattern 31 in the direction parallel to the short sides of the first surface 21 is gradually increased in the set area G of the first surface 21-a in the direction parallel to the long sides of the first surface 21-a. So that the surface of the shell presents the following anti-dazzle effect: the anti-glare effect of the set region G is gradually enhanced in a direction parallel to the long sides of the first surface 21.

For another example, as shown in FIG. 5G, the set direction AB is parallel to one set of short sides of a set pair of sides of the first surface 21-a, and the size of each projection pattern 31 in the direction parallel to the long sides of the first surface 21-a is gradually increased in a set area G of the first surface 21-a in the direction parallel to the short sides of the first surface 21-a. So that the surface of the shell presents the following anti-dazzle effect: the anti-glare effect of the set area G is gradually enhanced in a direction parallel to the short side of the first surface 21-a.

As a further possible design, the setting direction AB is parallel to the diagonal of the first surface 21-a. As shown in fig. 5h, the set direction AB is parallel to a diagonal line of the first surface 21-a, and the size of each projection pattern 31 in a direction perpendicular to the diagonal line of the first surface 21-a is gradually increased in a set area G of the first surface 21-a in a direction parallel to the diagonal line of the first surface 21-a. So that the surface of the shell presents the following anti-dazzle effect: the anti-glare effect of the set region G is gradually enhanced in a direction parallel to a diagonal line of the first surface 21-a.

As yet another possible design, the setting direction AB is parallel to a line direction extending from one side to the other of a set of opposite sides of the first surface 21-a and not parallel to the sides of the first surface 21-a. As shown in fig. 5i, the size of each projection pattern 31 in the direction perpendicular to the set direction AB gradually increases along a line direction extending from one side to the other of one of the short sides of the pair of pairs parallel to the first surface 21-a and not parallel to the long side of the first surface 21-a. The anti-glare effect presented by the surface of the shell is thus: the anti-glare effect of the set region G is gradually enhanced in a line direction extending from one of a set of short sides of a set of pairs parallel to the first surface 21-a to the other and not parallel to the long side of the first surface 21-a.

In some embodiments, the first surface 21-a further includes a bright-surface region G 'and/or an anti-glare region G'. Wherein the bright surface region G ″ is located at the first side S of the set region G, the anti-glare region G 'is located at the second side F of the set region G, and the anti-glare region G' is provided with the anti-glare microstructures 22.

Note that the first side S and the second side F of the setting region G are opposite sides of the setting region G in the setting direction AB, respectively.

Based on the above embodiments, as some possible designs, the first surface 21-a of the housing base material includes the bright area G ″ and the set area G, and the bright area G ″ is located on the first side S of the set area G. Alternatively, the first surface 21-a includes an anti-glare region G 'and a set region G, the anti-glare region G' being located at the second side F of the set region G. Alternatively, the first surface 21-a includes a bright surface region G ", an anti-glare region G ', and a set region G, the bright surface region G and the anti-glare region G' being located at the first side S and the second side F of the set region G, respectively. Alternatively, the first surface 21-a includes only the set region G.

Illustratively, as shown in fig. 5a to 5c, the first surface 21-a of the housing 2 includes a bright surface region G ", a set region G, and an anti-glare region G', which are respectively located on the first side S and the second side F of the set region G. Due to the fact that in the set region G, along the set direction AB, the plurality of sub-regions G₁The area of the region in which the anti-glare microstructures 22 are disposed increases in order, and thus, one sub-region G on the first side S of the set region G₁Up (i.e. in the set direction AB the plurality of sub-regions G₁First sub-region G of₁) The area of the region where the anti-glare microstructures 22 are provided is the smallest, and the area of the region having the anti-glare effect is the smallest; last sub-area G on second side F of the set area G₁(i.e. in the set direction AB the plurality of sub-regions G₁Of the last sub-region G₁) The area of the region where the antiglare microstructure 22 is provided is the largest, and the area of the region having an antiglare effect is the largest.

Illustratively, as shown in fig. 5d to 5i, the first surface 21-a of the housing 2 includes a bright surface region G ", a set region G, and an anti-glare region G', which are respectively located on the first side S and the second side F of the set region G. Since the size of each projection pattern 31 in the direction perpendicular to the setting direction AB is gradually increased in the setting region G along the setting direction AB, the size of each projection pattern 31 in the direction perpendicular to the setting direction AB is minimized on the first side S of the setting region G; on the second side F of the setting region G, the size of each projection pattern 31 in the direction perpendicular to the setting direction AB is largest.

Thus, the engagement between the bright surface region G ″ and the set region G, the set region G and the anti-glare region G' is natural on the first surface 21-a of the housing base material 21. Because along the set direction AB, namely the direction that the bright surface area G 'points to the anti-glare area G', the anti-glare effect presented by the set area G is gradually enhanced, therefore, under the transition effect of the set area G, no obvious boundary exists between the bright surface area G 'and the anti-glare area G', the transition is natural, a better visual effect is formed, the hand feeling is smoother, and better tactile experience is achieved.

In some embodiments, as shown in fig. 6a, the housing 2 further includes a decoration film 23 covering the second surface 21-b of the housing base material 21, the decoration film 23 including: a color layer 231 and an ink layer 232 disposed on a side of the color layer 231 facing away from the housing base material 21.

In the above embodiment, the decoration film 23 is used to decorate the case base material 21 so that the case surface exhibits a good visual effect. The color layer 231 is a film layer capable of presenting multiple colors, and for example, the color layer 231 may be a gradient color coating film, or a film layer presenting a certain color (such as pink, light blue, gold, silver, gray, etc.). The ink layer 232 is used for matching with the color layer 231, so that the surface of the shell presents colors, and the visual effect is improved.

In some embodiments, as shown in fig. 6b, the decoration film 23 further includes a substrate layer 233, and the substrate layer 233 is disposed on a side of the color layer 231 facing the housing base material 21.

In the above embodiment, the substrate layer 233 serves to enhance the strength and rigidity of the case 2, so that the explosion-proof capability of the case 2 is improved. Illustratively, the substrate layer 233 includes a PET (Polyethylene terephthalate) film 2331 with OCA (Optically Clear Adhesive), and a UV (ultraviolet ray) Adhesive textured layer 2332, wherein the PET film 2331 with OCA has excellent mechanical properties, high toughness, and adhesiveness, and can be stably attached to the second surface 21-b of the housing base material 21, so that the strength and hardness of the housing 2 can be improved. The UV glue texture layer 2332 has high adhesive strength, is used to closely adhere the color layer 231 to the PET film 2331 with OCA, is not easily peeled off, has a set texture, and can improve the visual effect of the housing 2.

As a possible design, referring to fig. 6b again, the housing 2 further includes an AF (anti-finger) fingerprint-proof protective film 24 covering the first surface 21-a of the housing base material 21, and the AF fingerprint-proof protective film 24 can thin and decompose fingerprint grease, reduce the visibility of fingerprints on the housing surface, and perform a fingerprint-proof function.

Some embodiments of the present application further provide a terminal device, where the terminal device includes a display screen, and a housing disposed on one side of the display screen, where the housing is the housing 2 as described in the above embodiments. This casing 2 can regard as terminal equipment's backshell, because this terminal equipment's backshell surface can present the anti-dazzle effect of gradual change, and the whole transition nature of the anti-dazzle effect on the surface of backshell feels smooth, can bring user's splendid visual experience and touch experience.

In some embodiments, the terminal device is a mobile phone, and the rear shell of the mobile phone is the housing 2 described in the above embodiments. As shown in fig. 7, functional components such as a camera c, fingerprint recognition f, infrared sensing i, etc. in the cellular phone are disposed in an area where the anti-glare effect is the weakest on the surface of the housing 2, or in a bright area, for the convenience of user operation.
