Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present disclosure.

Fig. 1 is a schematic diagram illustrating a structure of a display screen according to the present application.

As can be seen from fig. 1, the display screen includes: optical film layer 101, light source array layer 102, and light source drive board 103.

Wherein, a plurality of light emitting devices are arranged in the light source array layer.

The light emitting device may also have a variety of possibilities in this application depending on the type of liquid crystal display in the display.

In a possible case, the display screen is a light-emitting diode (LED) liquid crystal display screen, and the light source array layer may be an LED light source array layer, and correspondingly, the LED light source array layer may be disposed with a plurality of LED light emitting elements, and the LED light emitting elements may be LED light emitting chips or LED backlight beads.

In an alternative, to achieve high contrast and high brightness of the display, the LED display may be a MiniLED liquid crystal display, which is a liquid crystal display that employs sub-millimeter light emitting diodes (minileds). Correspondingly, the LED light source array layer may include a plurality of MiniLED light emitting chips or MiniLED backlight beads.

Wherein, there is an electrical connection between the light source driving board 103 and the light source array layer 102.

The light source driving board is loaded with a driving circuit, and the light emitting devices in the light source array layer can be driven to emit light through the light source driving board.

The optical film layer is located on the upper layer of the light source array layer, and light emitted by the light source array layer is projected out through the optical film layer finally, so that a user can see an image displayed on the display screen.

In the present application, the light source array layer 102 is between the light source driving board 103 and the optical film layer 101, and a space 104 as a light mixing region is provided between the light source array layer 102 and the optical film layer 101. Wherein the light emitted from each light emitting device in the light source array layer is mixed in the space 104.

As shown in fig. 1, the space between the light source array layer 102 and the optical film layer 101 is a hollow cavity layer, which is an air layer without any physical devices.

Because the spacing space is arranged between the light source array layer and the optical film layer, light emitted by the light source on the light source array layer can be uniformly mixed in the spacing space, so that point light sources emitted by the light source in the light source array layer are uniformly mixed into a surface light source.

The height of the spacing space can be set as required, and in order to enable the light emitted by the light source array layer to be sufficiently mixed, the height of the spacing space should be not less than 0.1 mm.

In an alternative, the height of the spacing space is 0.2 mm to 0.3 mm.

It will be appreciated that there are many possible ways of forming a spacing space between the light source array layer and the optical film layer, and this application is not limited thereto.

In an alternative mode, in the present application, the light source array layer and the optical film layer may be separated by a spacing space through a support spacer. Correspondingly, the spacing space is a hollow separation layer between the light source array layer and the optical membrane layer.

The supporting gasket can be positioned at the edges of the side edges of the light source array layer and the optical film layer so as to avoid blocking light emitted by the light source array layer.

Therefore, in the display screen of the application, the spacing space serving as the light mixing area is formed between the light source array layer and the optical film layer, and on the basis, light emitted by each light emitting device in the light source array layer can be mixed in the spacing space, so that optical films such as a light splitting film and a diffusion sheet for realizing light mixing are reduced or even not required to be separately arranged, device resources required by the display screen for realizing light mixing can be reduced, and resource consumption is reduced.

It will be appreciated that in the present application the optical film layer generally comprises a plurality of optical films, some of which may be the same type of optical film and some of which may be different types of optical films.

There are also many possibilities for the arrangement of the optical film in the optical film layer in the present application.

In a possible implementation manner, in order to reduce the power consumption of the display screen, the number of light emitting devices in the light source array layer can be reduced compared with the light source array layer in the existing display screen.

For example, for the MiniLED light source array layer, since the power consumption of the MiniLED light emitting device is high, in order to reduce the power consumption, the number of MiniLED light emitting chips or backlight beads may be reduced. For example, the display screen may be reduced to sixty percent from the number of the light emitting devices in the existing arrangement, for example, if there are 1 ten thousand light emitting chips in the current MiniLED light source array layer, the MiniLED light source array layer may be reduced to have 6 thousand light emitting chips in the present application.

After the number of the light emitting devices in the light source array layer is reduced, in order to ensure the display effect of each position point in the display screen, the light sources emitted by each light emitting device in the light source array layer need to be more fully mixed to ensure the uniformity of the surface light source. On this basis, in order to ensure the light mixing effect, the light mixing layer for realizing light mixing can be contained in the optical film layer while a spacing space is arranged between the light source array layer and the optical film layer, wherein the light mixing layer can comprise at least one diffusion sheet and one light splitting film.

The at least one diffusion sheet is stacked with the light splitting film in order from top to bottom, and the top-to-bottom direction mentioned herein is a direction from the outermost layer of the screen of the display panel to the light source driving board.

As shown in fig. 2, it shows a schematic view of a cross-sectional component structure of an electronic device having a display screen of the present application.

Fig. 2 is a cross-sectional view from the front panel side to the back panel side of the display screen.

As can be seen from fig. 2, the display screen includes an optical film layer 201, a light source array layer 202 and a power supply driving board 203 in sequence from top to bottom.

Wherein, the optical film layer comprises a polarized light layer 2011, a diffusion sheet, a prism layer, a light mixing layer 2012 and a quantum dot film which are stacked in sequence from top to bottom.

In one possible implementation, the polarized light layer 2011 may include an upper polarized light layer, a Color filter (also referred to as Color Filter (CF) glass), a TFT glass, and a lower polarized light layer, which are stacked in sequence.

Among them, a TFT (thin film transistor) is a glass called TFT glass in which a conductive film is formed on a glass or plastic substrate by sputtering or chemical deposition, and various large-scale circuits are formed by processing the conductive film.

The quantum dot film is mainly used for mixing light into white light.

The prism layer may include two prism sheets, and the prism layer may improve optical utilization.

As can be seen from fig. 2, the light mixing layer 2012 may include two diffusion sheets and a light splitting film stacked in sequence.

As can be seen from fig. 2, after the light emitted from the light source array layer passes through the spacing space 204 between the optical film layer 201 and the light source array layer 202 and is mixed, the mixed light continues to be mixed through the light mixing layer 2012 during the upward continuous propagation process, so that even if the number of the light sources in the light source array layer is reduced, the light emitted from the light sources in the present application is mixed twice to uniformly mix the light of the light sources, and the situation that the uniform surface light source cannot be formed due to insufficient light mixing caused by the reduction of the number of the light sources can be reduced.

In yet another possible implementation of the present application, the optical film layer may include a polarizing layer, a diffusion sheet, a prism layer, and a quantum dot film, which are sequentially stacked. In this possible case, the optical film layer removes the two diffusion sheets and the light splitting film as the light mixing layer in fig. 2.

Because the display screen is provided with the spacing space as the light mixing area, the light emitted by the light source array layer can be mixed through the spacing space, and therefore, the light source light mixing cannot be influenced after the diffusion sheet and the light splitting film are removed from the optical film layer.

Meanwhile, after the diffusion sheet and the light splitting film are removed from the optical film layer, the resource consumption caused by the arrangement of the diffusion sheet and the light splitting film can be reduced, and the thickness space occupied by the arrangement of the diffusion sheet and the light splitting film can be reduced, so that the thickness of the display screen can be reduced.

In addition, since the thickness of the space is lower than those of the diffusion sheet and the light splitting film, the thickness of the display screen can be reduced by providing the space instead of the diffusion sheet and the light splitting film.

For convenience of understanding, the case of the display screen being a MiniLED liquid crystal display screen is taken as an example, and the light source array layer in the display screen is illustrated by a MiniLED light source array layer. See, for example, fig. 3, which shows a schematic cross-sectional view of a display screen of the present application.

As can be seen from fig. 3, the display screen may include: optical film layer 301, MiniLED light source array layer 302 and MiniLED light source driver board 303.

In fig. 3, the MiniLED light source array layer is also referred to as a MiniLED array, and specifically includes a plurality of MiniLED light emitting chips. Here, the MiniLED light emitting chip is taken as an example for description, and the LED light emitting chip is replaced with the LED backlight bead similarly.

Correspondingly, the light source driving board in fig. 3 is a MiniLED light source driving board, and the MiniLED light source driving board may drive the MiniLED light source array to emit light, and may only control a part of the minileds in the MiniLED light source array to emit light according to the control instruction.

It can be understood that, for the MiniLED lcd, the backlight source is a direct-type MiniLED, and thus, a point light source is emitted upward from the light source point of each MiniLED light emitting chip in fig. 3.

In the present application, since the MiniLED light source array layer 302 and the optical film layer 301 have a hollow space 304 therebetween, the light emitted from the MiniLED light sources is uniformly mixed in the space. As shown in fig. 3, the light beams emitted by the minileds overlap with each other to form a uniform surface light source.

In fig. 3, the optical film layer 301 includes a polarizing layer 3011, a diffusion sheet, two prism sheets, and a quantum dot film stacked in this order from top to bottom, and does not include a light mixing region formed by the optical film.

The composition of the polarized light layer 3011 can be seen from fig. 3 and described above, and is not described here again.

It can be understood that, with the continuous development of electronic devices, people have higher and higher requirements for the lightness and thinness of electronic devices, and therefore, the thickness and weight of the display screen need to be reduced.

In order to reduce the thickness and weight of the display screen, in any of the above embodiments of the present application, the light source driving board of the display screen may be a supporting panel carrying a light source driving circuit. On this basis, because the support of support panel is higher, consequently need not the support panel outside of display screen and is establishing the metal protective housing at the cover.

The metal protective shell on the outer side of the power supply driving board is reduced, so that the thickness of a module of a display screen of the electronic equipment can be reduced, and the resource consumption caused by the arrangement of the metal protective shell can also be reduced.

Furthermore, in order to reduce the resource consumption of the electronic equipment and reduce the thickness of the electronic equipment body provided with the display screen module, the support panel bearing the drive circuit in the application can also be directly used as a shell for supporting or protecting the display screen in the electronic equipment, namely, a back plate of the display screen in the electronic equipment.

It can be understood that, by using the supporting panel carrying the driving circuit as the housing (or the back panel) of the display screen in the electronic device, the material required for separately setting the housing of the display screen is not needed, and the rear end of the housing can be reduced, thereby reducing the overall thickness of the display screen in the electronic device.

In the present application, the supporting panel may be a glass substrate, and may also be a rigid printed circuit board.

When the glass substrate is adopted to bear the driving circuit for driving the light source array layer, in order to beautify the back plate of the display screen in the electronic equipment or make the internal devices of the display screen invisible, the glass substrate can be sprayed with patterns or pigments and the like.

Accordingly, if the support panel is a rigid Printed Circuit Board (PCB), a shielding layer is sprayed on a surface of the rigid PCB facing the outside of the display screen (i.e., a surface facing away from the light source array layer), or a decorative film is attached as a decoration to form a decorative surface. The thickness of the decorative film is much thinner than that of the outer shell of the current display screen.

Of course, the supporting panel may be in other forms, as long as it is a hard panel capable of carrying the driving circuit and serving as a back plate of the display screen.

For the convenience of understanding, fig. 3 is taken as an example, and it can be seen from fig. 3 that the MiniLED driving board 303 is a hard PCB or a glass substrate, and on the basis, a decorative surface 305 serving as a decoration may be adhered to an outer surface of the glass substrate or the hard PCB, so that a metal protective shell of the driving board does not need to be separately provided, and a housing of the display screen does not need to be provided outside the metal protective shell.

To facilitate an understanding of the benefits of FIG. 3, a description is made in comparison to FIG. 2. As can be seen from fig. 2, a screen metal shell 205 is attached to the power supply driving board 203 through a double-sided adhesive tape, and the screen metal shell 205 is attached to a housing 206 supporting a display screen in the electronic device through a double-sided adhesive tape. Therefore, compared with fig. 2, the electronic device in fig. 3 can reduce the thickness of the screen metal protective shell, the shell and the double-sided adhesive tape used for pasting, which is beneficial to reducing the thickness of the body where the display screen is located in the electronic device, and can also reduce consumables and reduce resource consumption.

In yet another possible implementation, the light source driving board is a flexible printed circuit board carrying the light source driving circuit in order to reduce the thickness and weight of the display screen. In this case, since the flexible printed circuit board has flexibility, the flexible printed circuit board can be directly attached to an inner side surface of a case supporting or accommodating the display screen in the electronic apparatus.

Therefore, when the display screen is assembled to form the display screen body of the electronic equipment as a module, the flexible factor circuit board can be directly pasted on the inner side surface of the shell of the display screen in the electronic equipment, so that a metal protective shell does not need to be arranged for the module of the display screen independently, and the thickness and the consumable materials occupied by the metal protective shell can be reduced.

For the possible implementation manner, an electronic device assembled by using the display screen in the implementation manner as a module is described as an example, and details are not repeated herein.

It is understood that in the present application, the display screen as a module may further include a support capable of supporting the optical film layer, the light source array layer and the light source driving board in the display screen. The optical diaphragm layer, the light source array layer and the light source driving board can be combined together through the supporting piece to form a module of the display screen.

Wherein, the specific form of the supporting member may be different according to the specific composition of the display screen.

If, under the condition that the light source drive plate of display screen is support panel, because support panel can be arranged in the backplate of display screen among the electronic equipment, on this basis, support piece can be for being used for blocking buckle or the module support piece of optics diaphragm layer, light source array layer and light source drive plate, buckle or module support piece are located the both ends of this module of display screen to can not shelter from the display panel of display screen and the light source drive plate as the backplate.

As shown in fig. 3, the optical film layer 301, the light source array layer 302 and the light source driving board 303 are fixed by the edge support 306 in the display screen.

In fig. 3, only one side of the supporting member is shown for more fully showing the components of the display screen, and in practical applications, the supporting member may be disposed on two parallel sides of the display screen or disposed around the display screen. Fig. 4 is a schematic cross-sectional view of a display screen in the case of using a light source driving board as a supporting panel.

As can be seen from fig. 4, the supporting members 401 are disposed on both sides of the display screen, and the supporting members on both sides of the display screen can fix the components (not explicitly indicated in the figure, but only schematically illustrated) in the display screen module, and as can be seen from fig. 4, the glass substrate or PCB 402 carrying the driving circuit in the assembled display screen serves as a protection board of the display screen module, and no separate screen protection shell is disposed.

In yet another possible implementation manner, if the light source driving board of the display screen is a flexible circuit board, then in addition to the components in the module of the display screen being combined together by means of pasting or the like in this application, the housing of the electronic device may also be used as a support for the display screen, and the following result is illustrated in fig. 5.

It can be understood that the above is introduced from the perspective of the display screen module, and in practical applications, the display screen module may be applied to an electronic device, and finally forms a display screen in the electronic device.

Correspondingly, the present application also provides an electronic device, which includes: a display screen.

Wherein, the display screen includes: the light source driving board comprises an optical diaphragm layer, a light source array layer and a light source driving board;

wherein, a plurality of light emitting devices are arranged on the light source array layer;

the light source driving board is electrically connected with the light source array layer;

the light source array layer is arranged between the light source driving board and the optical diaphragm layer, and a spacing space serving as a light mixing area is formed between the light source array and the optical diaphragm layer, wherein light emitted by each light emitting device in the light source array layer is mixed in the spacing space.

Similar to the previous display embodiments, the light source array layer may have a variety of possibilities.

In one possible case, the light source array layer may be an LED light source array layer, in which case the LED light source array layer comprises a plurality of LED lighting chips or backlight beads, e.g. the LED light source array layer may be a MiniLED light source array layer comprising: a plurality of MiniLED light emitting chips or backlight beads.

Accordingly, the light source driving board may be a circuit board that drives MiniLED, i.e., a MiniLED light source driving board.

There are also a number of possibilities for the composition of the optical film layer in this embodiment. As one possible scenario, the optical film layer may include a polarizing layer, a diffuser, a prism layer, a light mixing layer, and a quantum dot film stacked in this order, and may be specifically as described above in the optical film layer in the display of fig. 2.

In another possible implementation manner, in order to reduce the thickness of a display screen in an electronic device to achieve light and thin, the optical film layer may also have a light mixing layer removed, and thus, the optical film layer may include a polarizing layer, a diffusion sheet, a prism layer, and a quantum dot film, which are stacked in sequence.

It can be understood that the thickness of the display screen of the electronic device can be reduced by reducing the light mixing area in the optical film layer, the weight of the electronic device is reduced, and the material consumption of the electronic device is also reduced. For example, the electronic device is a mobile phone, and the mobile phone can be thinned by reducing the thickness of the display screen.

For specific structural relationships among the light source array layer, the light source driving board, and the optical film layer in the display screen of the electronic device, reference may be made to the related descriptions of the foregoing embodiments, which are not described herein again.

It can be understood that, the light source driving board in the module of the display screen in the present application may have various structural forms, and under the condition that the light source driving board is different, the specific form of the electronic device having the display screen may also be different.

For example, in one possible case, the light source driving board in the display screen of the electronic device may be a support panel carrying the light source driving circuit, for example, the support panel may be the aforementioned glass substrate or a rigid PCB board, as described above.

In this case, the electronic device does not need to separately provide a back plate or a housing for the display screen, but directly uses the support panel of the display screen, which carries the light source driving circuit, as the housing or the back plate of the electronic device. Simultaneously, if be provided with support piece on this module of display screen, then need not alone again to set up support piece for the display screen, if this module of display screen does not have support piece, then can set up support piece around or in the both sides of display screen.

If the display panel of the electronic device is a MiniLED liquid crystal display panel, for example, and the light source driving panel is a supporting panel, the partial sectional structure diagram of the electronic device is actually the partial sectional structure diagram of the display panel shown in fig. 3.

As can be seen from fig. 3, in the MIniLED liquid crystal display of the electronic device, each MIniLED light source (such as a light emitting chip or a backlight bead) in the MIniLED array is a direct type. Meanwhile, a spacing space is formed between the MiniLED array 302 and the quantum dot film, so that the dot light sources emitted upwards by each light emitting source in the MiniLED array can mix light in the spacing space.

Therefore, even if the optical film layer does not include the light mixing layer any more, the uniform light mixing of the MiniLED light source is not affected, but the thickness of the display screen occupied by the light mixing layer can be reduced, so that the thickness of the display screen presented by the electronic equipment is reduced, and the weight of the electronic equipment can be reduced.

Further, in this application, in the electronic device, the glass substrate or the PCB board where the MiniLED driving circuit of the display screen is located is directly used as the housing (or the back plate) of the display screen in the electronic device. As can be seen from fig. 3 and 4, no other housing is provided outside the PCB board or the glass substrate of the MiniLED driving board as the display screen of the electronic device.

Because directly regard as the backplate of display screen among the electronic equipment with MiniLED drive plate in the display screen, can avoid electronic equipment to set up casing or backplate alone and thickness and weight that increases for the display screen, also can reduce electronic equipment's consumptive material naturally.

Of course, the electronic device may further include a supporting member, which may be considered as a component of the module of the display screen, or may be considered as a component set for fixing the display screen by the electronic device, as shown in the supporting member 306 in fig. 3 and the supporting member 401 in fig. 4, and details thereof are not repeated.

In yet another possible implementation, the light source driving board in the display screen of the electronic device may be a flexible printed circuit board carrying the light source driving circuit.

In this case, the electronic device may further include: a housing containing a display screen. Accordingly, the flexible printed circuit board in the display screen may be adhered to the inner side surface of the case so that the display screen may be assembled and fixed to the electronic device.

The specific form of the shell can be set according to the requirement, for example, the shell can cover the back and the side of the display screen.

For ease of understanding, the following description of this implementation is provided in connection with a specific application scenario.

The display screen of the electronic device is still exemplified as the MiniLED liquid crystal display screen.

Fig. 5 is a schematic cross-sectional view of an electronic device according to the present application.

In fig. 5, the electronic apparatus includes a display screen and a housing accommodating the display screen.

As shown in fig. 5, the display screen may include: optical film layer 501, light source array layer 502 and light source drive board 503. Wherein, the light source driving board is electrically connected with the light source array layer;

the light source array layer can be a MiniLED array, and a plurality of MiniLED light-emitting chips (or backlight beads) are arranged on the MiniLED array. The MiniLED light-emitting chips are arranged in a direct type mode.

Correspondingly, the light source driving board is a MiniLED light source driving board.

As can be seen from fig. 5, a MiniLED array 502 is located between the MiniLED light source driving board 503 and the optical film layer 501, and a space 504 as a light mixing area is provided between the light source array and the optical film layer.

In fig. 5, the optical film layer includes an upper polarizer (also referred to as an upper polarizer), a CF glass layer, a TFT glass, a lower polarizer (also referred to as a lower polarizer), a diffusion sheet, a prism layer, a light mixing layer, and a quantum dot film, which are sequentially stacked. It can be seen that the optical film layer does not include a light mixing layer, so that the thickness of a display screen in an electronic device can be reduced. Of course, fig. 5 is only an example of an optical film layer, and if the optical film layer is other, or includes a light mixing layer, the embodiment is also applicable, and the invention is not limited thereto.

In fig. 5, the MiniLED light driving plate is a flexible circuit board, and on this basis, the flexible circuit board may be adhered to the casing 505 of the electronic device by a double-sided adhesive tape, and since a screen metal protective casing for protecting the circuit board in the display screen is not provided in the display screen, and the casing 505 of the electronic device is directly reused as the metal protective casing of the display screen, the overall thickness and weight of the electronic device assembled with the display screen may be reduced, and resource consumption may also be reduced.

In fig. 5, the housing of the electronic device may cover the back and four sides of the display screen, thereby serving as both the housing of the electronic device and the metal protective shell of the circuit board of the display screen.

It can be understood that, on the basis that the display screen has the screen metal protective shell, the screen metal protective shell is actually the shell of the electronic device, that is, in the electronic device, the shell of the display screen and the screen metal protective shell of the display screen are the same.
