Technical Field

The application belongs to the technical field of electronic equipment, and particularly relates to electronic equipment.

Background

In order to realize the self-photographing function, a front camera is often arranged in the electronic equipment. The setting of leading camera needs trompil on the screen. The opening affects the display effect of the screen, which results in an off-screen camera.

For an electronic device using an off-screen camera, the display area of the display panel generally includes a normal display area and a displayable off-screen camera area. In order to improve the Light transmittance and satisfy the photographing requirement, the camera area under the screen generally adopts the modes of reducing the pixel density, reducing the pixel size, and designing the cathode and the anode of an Organic Light-Emitting Diode (OLED) into a transparent structure to increase the Light transmittance.

However, in order to increase the light transmittance, the OLED electrode is designed as a transparent anode, which is likely to cause problems such as uneven display, inconsistent life attenuation of the light-emitting materials in different regions, and the like. In addition, a display element and a corresponding driving element are still arranged in the space right above the camera, so that light is inevitably blocked, and the light transmittance of the area cannot meet the requirement.

Disclosure of Invention

The application aims at providing an electronic device, and the problem that a display element above a camera affects light transmittance is at least solved.

In order to solve the technical problem, the present application is implemented as follows:

an embodiment of the present application provides an electronic device, including: a camera; a carrier for supporting a camera; the light-emitting piece is arranged on the carrier; the display layer is arranged on one side of the camera, and is provided with a first through hole which is opposite to the camera; the first electrochromic layer is arranged in the first through hole.

In an embodiment of the application, a first electrochromic layer is provided at a position where the display layer corresponds to the camera. By means of the energization, the coloring of the first electrochromic layer can be controlled so that a pattern corresponding to the entire screen appears at that position, or light is transmitted without displaying the pattern. When the pattern is displayed, the first electrochromic layer can be supplemented with light by setting and lighting the light-emitting piece, and the display effect of the first electrochromic layer is improved. In addition, the first electrochromic layer and the luminescent part are matched for display, so that the electrode of the display layer does not need to be designed into a transparent anode, and the problems of uneven display, inconsistent service life attenuation of luminescent materials in different areas and the like are avoided. Further, the first electrochromic layer can fade to be transparent through the change of current and voltage when the first electrochromic layer is powered on, so that the first electrochromic layer is changed into a transparent or nearly transparent state in the shooting mode of the electronic equipment, light cannot be blocked from being transmitted to the camera, and the light transmittance during shooting can be ensured. In short, through the setting and the cooperation of first electrochromic layer and illuminating part for the top of camera, the position that is also close to the screen can keep display element, ensures the display effect of screen at the camera position, simultaneously, when needs were made a video recording, can guarantee the luminousness again, has promoted the convenience that electronic equipment used.

An electronic device according to an embodiment of the present application is described below with reference to fig. 1 to 5.

As shown in fig. 1 and 2, an electronic device is provided according to some embodiments of the present application. The electronic device comprises a camera head 100, a carrier 102, a light emitting element 104, a display layer 106 and a first electrochromic layer 108.

Specifically, the camera head 100 and the light emitting member 104 are both disposed on the carrier 102. The display layer 106 is provided on one side of the camera head 100. The display layer 106 is provided with a first via 1084. The first through hole 1084 is located at a position on the display layer 106 opposite to the camera 100. The first electrochromic layer 108 is disposed within the first via 1084.

The first electrochromic layer 108 is made of electrochromic materials. Under the action of an applied electric field, the optical properties of the electroluminescent material, such as reflectivity, transmittance, absorptivity and the like, generate stable and reversible color change, and the electroluminescent material is presented with reversible changes of color and transparency in appearance. By utilizing the characteristics of the electrochromic material, the first electrochromic layer 108 may have a colored state and a transparent state, thereby displaying a pattern, and may become transparent to allow light to pass therethrough.

It is understood that both the colored state and the transparent state are essentially changes in light transmittance. In the transparent state, the light transmittance can theoretically reach 100%. The light transmission is typically only close to 100% due to the presence of impurities. Therefore, the range of light transmittance may be set to achieve both the purpose of coloring the first electrochromic layer 108 to display a pattern or the purpose of transmitting light.

Specifically, the electronic apparatus has an image capturing mode and a display mode. In the display mode, the first electrochromic layer 108 is colored and displays a pattern. Meanwhile, the illuminating element 104 is lighted to supplement light for the first electrochromic layer 108, so that the color of the pattern is more vivid, and the overall display effect of the screen is more consistent. It is understood that, when coloring, the light transmittance of the first electrochromic layer 108 is within a range, i.e., greater than or equal to a first preset value, and less than or equal to a second preset value. For example, the first preset value is 5%, and the second preset value is 90%. Of course, the first preset value and the second preset value may be other values. The smaller the light transmittance, the less likely the light passes through. The greater the light transmittance, the more easily light passes through. The closer the light transmittance is to 100%, the higher the transparency of the first electrochromic layer 108, and the easier it is for light to pass through. Therefore, in the image pickup mode, the first electrochromic layer 108 is discolored. The first electrochromic layer 108 fades to transparent or near transparent and the light emitting element 104 is off. The faded transparent first electrochromic layer 108 allows light to pass through more easily for photographing. When the first electrochromic layer 108 fades, the transparency thereof is greater than or equal to a third preset value, and the third preset value is greater than the second preset value. For example, the third preset value is any one of 90%, 93%, 96%, 99%, 100%.

Specifically, the first electrochromic layer 108 is disposed at a position of the display layer 106 corresponding to the camera 100, and the light emitting element 104 is disposed on the carrier 102 of the camera 100, so that the first electrochromic layer 108 and the light emitting element 104 cooperate to display, and thus, the electrode of the display layer 106 does not need to be designed as a transparent anode, which is beneficial to avoiding the problems of uneven display, inconsistent service life attenuation of the light emitting materials in different regions, and the like. Further, the first electrochromic layer 108 may fade to be transparent when being powered on, so that the first electrochromic layer 108 may change to be transparent when the electronic device is in the image capturing mode, and light cannot be blocked from being transmitted to the camera 100, so that light transmittance during image capturing may be ensured. In short, through the setting and the cooperation of first electrochromic layer 108 and luminous part 104 for camera 100's top, the position that is also close to the screen can keep display element, need not reduce pixel density, reduce pixel size etc. is favorable to guaranteeing the display effect of screen in camera 100 position, and simultaneously, when needs were made a video recording, can guarantee the luminousness again, has promoted the convenience that electronic equipment used.

Further, the first electrochromic layer 108 includes a plurality of differently colored first pixel regions 1080. Through setting up a plurality of different first pixel areas 1080 that stain, be favorable to under the display mode, form different patterns to the holistic pattern of cooperation screen makes screen display effect better, has avoided camera 100 to the influence of screen display effect under the screen. It is understood that the plurality of first pixel regions 1080 are disposed at intervals to avoid color mixing. Meanwhile, the first pixel regions 1080 have different colors and different light transmittances. The plurality of first pixel regions 1080 with different colors and different light transmittance can display more different patterns, which is beneficial to improving the richness of screen display.

Further, the coloring of the plurality of first pixel regions 1080 includes red, green and blue. Or any combination of these three colors. It is understood that red, green or blue, are three primary colors. Adopt red, green, blue to be a plurality of first pixel district 1080 coloring, perhaps make up it, be convenient for construct rich and varied pattern through a plurality of first pixel district 1080 to can cooperate with the screen is whole better, promote the display effect under the display mode, reduce the influence of camera 100 under the screen to the demonstration, promote the comfort level that the user watched the screen.

In any of the above embodiments, the first electrochromic layer 108 further includes a first black matrix 1082. In the display mode, the light transmittance of the first black matrix 1082 is less than the first preset value. The first black matrix 1082 is disposed between the adjacent first pixel regions 1080. Like this, through the setting of first black matrix 1082, be favorable to the pixel interference between the adjacent first pixel district 1080 of separation, promote the accuracy of the pattern that each first pixel district 1080 constructed, guarantee the display effect. It can be understood that, in the display mode, the light transmittance of the first black matrix 1082 is smaller than the first preset value, that is, smaller than the minimum light transmittance of the first pixel region 1080, so that the first pixel regions can be easily distinguished from each other, and the first pixel regions 1080 can be prevented from being influenced by each other. Preferably, the coloring of the first black matrix 1082 is black. The black color is selected, and the light transmittance is 0 or close to 0, which is beneficial to better distinguish the adjacent first pixel regions 1080. In the image capturing mode, the light transmittance of the first black matrix 1082 is greater than the third predetermined value, so as to transmit light.

In any of the above embodiments, the electronic device further comprises a protective layer 110. The protective layer 110 is disposed between the display layer 106 and the camera head 100. By arranging the protective layer 110 between the display layer 106 and the camera head 100, the camera head 100 and the display layer 106 can be isolated, mutual working interference between the two is reduced, and protection is provided for the camera head 100.

Further, a second through hole 1124 is formed on the protection layer 110. The second through hole 1124 is provided at a position opposite to the camera head 100. A second electrochromic layer 112 is disposed within the second through-hole 1124. Like the first electrochromic layer 108, the second electrochromic layer 112 may have a colored state and a bleached state when energized. Specifically, in the display mode of the electronic device, the second electrochromic layer 112 is colored. That is, in the display mode, the second electrochromic layer 112 is in a colored state, and has a light transmittance between a first preset value and a second preset value. Under the mode of making a video recording, second electrochromic layer 112 fades to transparent, and its luminousness is greater than the third default, makes light not only can pass through first electrochromic layer 108, can also pass through second electrochromic layer 112 to promote the luminousness of electronic equipment under the mode of making a video recording.

The difference from the first electrochromic layer 108 is that the depth of coloration, or the light transmittance, is variable in at least a partial region of the second electrochromic layer 112. By varying the light transmittance, the depth of coloration of the second electrochromic layer 112 may also be varied. Thus, in the display mode, the color depth of the second electrochromic layer 112 is changed by changing the light transmittance of a partial region thereof. That is to say, the light quantity of the first electrochromic layer 108 that the light emitted by the light emitting element 104 is projected onto the display layer 106 is reduced, and correspondingly, the color on the first electrochromic layer 108 is changed accordingly, so that more patterns can be changed, the overall display effect of the screen can be better matched, and the adverse effect of the camera 100 under the screen on the overall display effect of the screen is reduced. It is understood that the change in the shade of coloration or the light transmittance of the first electrochromic layer 108 is achieved by means of a change in voltage or current. That is, the coloring depth of the partial region of the first electrochromic layer 108 varies with the variation of the applied voltage or current.

In some embodiments, the second electrochromic layer 112 includes a plurality of second pixel regions 1120 and a second black matrix 1122. A second black matrix 1122 is disposed between the adjacent second pixel regions 1120. In the display mode, the coloring of the plurality of second pixel regions 1120 is the same as the coloring of the second black matrix 1122, and the transmittance is the same. In the display mode, the light transmittance of the second black matrix 1122 and the second pixel region 1120 are both less than the first preset value. For example, the second black matrix 1122 and the second pixel region 1120 are both colored black. In the image capturing mode, the light transmittance of the second black matrix 1122 and the light transmittance of the second pixel region 1120 are both greater than a third predetermined value, so that light can pass through the second electrochromic layer 112.

The coloring depth or the light transmittance of the plurality of second pixel regions 1120 may vary according to the variation of the power-on voltage. The coloring of the second pixel region 1120 is black, which does not easily interfere with the coloring of the first pixel region 1080 on the first electrochromic layer 108, but only adjusts the light transmittance by changing the shade thereof. Meanwhile, the second pixel region 1120 and the second black matrix 1122 are both black in a colored state, which facilitates production. The second black matrix 1122 is provided to reduce the coloring interference to the adjacent first pixel area 1080 synchronously with the first black matrix 1082, thereby improving the accuracy of the pattern display of the first pixel area 1080.

It can be understood that the plurality of second pixel regions 1120 are also disposed at intervals and correspond to the first pixel regions 1080, so that when the light transmittance of the second pixel regions 1120 is changed, the color display of the corresponding first pixel regions 1080 is affected.

In any of the above embodiments, the electronic device further comprises a polarizing layer 114. The polarizing layer 114 is disposed on a side of the display layer 106 away from the camera 100. Alternatively, the polarizing layer 114 is disposed on a side of the camera head 100 on which light is incident, and the display layer 106 is between the polarizing layer 114 and the camera head 100. Through setting up polarizing layer 114, be favorable to eliminating or reducing the light reflection of plane shot object and disturb, promote the accuracy of making a video recording. Meanwhile, the polarizing layer 114 is further provided with a third through hole 1140. The transparent colloid 116 is disposed in the third through hole 1140. It is understood that the third through hole 1140 is provided corresponding to the camera head 100. That is, the third through hole 1140 is opposite to the camera head 100. Thus, the first through hole 1084, the second through hole 1124, and the third through hole 1140 are all coaxially disposed. The transparent colloid 116 is filled in the third through hole 1140, so that the light transmittance in the image capturing mode can be ensured. On the other hand, the transparent colloid 116 can reduce the light loss at the interface, effectively reduce the existence of the air-solid interface, reduce the interface reflection, and improve the display effect.

In any of the above embodiments, the camera head 100 is provided with a plurality of light emitting members 104 in the circumferential direction. By arranging the plurality of light emitting members 104, the backlight effect can be enhanced, and the display effect in the display mode can be improved. Meanwhile, the plurality of light emitting members 104 are arranged in the circumferential direction of the camera 100, which also facilitates providing backlight from a plurality of angles and reduces the shadow phenomenon.

Further, a plurality of light emitting elements 104 are embedded in the carrier 102. The light emitting element 104 is embedded in the carrier 102, so that the space occupied by the light emitting element 104 can be reduced, and the space utilization rate inside the electronic device can be improved. In some embodiments, the light emitting element 104 is flush with the surface of the carrier 102, i.e., the light emitting element 104 does not protrude from the carrier 102 at all, so that the Z-direction dimension of the electronic device, i.e., the dimension in the optical axis direction of the camera 100, can be reduced. Thus, the requirement of backlight irradiation of the display layer 106 can be met, the occupation of the Z-direction space of the electronic equipment can be avoided, and the miniaturization and light-weight design of the electronic equipment is facilitated.

It is understood that the light emitting member 104 includes a micro-light emitting diode or other light emitting element.

In any of the above embodiments, the electronic device further comprises a cover plate 118. The cover plate 118 is used to protect the display layer 106. Which is disposed on a side of the display layer 106 away from the camera head 100. When the polarizing layer 114 is provided, the cover plate 118 is disposed on a side of the polarizing layer 114 away from the camera 100. By providing the cover 118, both the light transmission and the protection of the display layer 106, the polarizing layer 114, and the like can be achieved.

The electronic equipment comprises any one of a mobile phone, a notebook computer, a tablet computer, a palm computer, a game machine and an intelligent watch.

According to an embodiment of the present application, an electronic device is provided with an off-screen camera 100. A displayable electrochromic structure is provided by placing a camera 100 area under the screen. The present embodiment removes the original display structure above the camera 100, fills with two patterned color-changing film layers and one optically transparent adhesive, and integrates a micro-light emitting element 104 on the lens carrier 102 of the camera 100. The color-changing film layer has an electrochromic function and has two states of coloring and transparency, wherein the coloring degree can be changed along with voltage, and under a camera shooting mode, the color-changing film becomes transparent, and because no light ray blocking element is arranged above the camera 100, the transmittance of light rays which can effectively enter the camera 100 can reach more than 70%. In the display mode, the color-changing film is colored, the micro light-emitting element 104 is lighted up to serve as a backlight to face the color-changing film layer, and the color-changing film layer realizes the display function through the control of the transmittance. The space thickness of the electronic equipment is not increased, the light and thin structure is facilitated, the controllability is high, the structure is simple, and the high-efficiency compatibility of the transmittance and the display picture is realized.

As shown in fig. 1 and fig. 2, it is a scheme of an off-screen camera 100 according to this embodiment. The display screen includes, from top to bottom, a cover plate 118, a polarizing layer 114, a display layer 106, and a protective layer 110. The layers are bonded through bonding glue. The position corresponding to the camera 100 under the screen is provided with a hole on the display screen. Specifically, the display layer 106 is provided with a first through hole 1084, the protection layer 110 is provided with a second through hole 1124, and the polarizing layer 114 is provided with a third through hole 1140. As shown in fig. 1, the first electrochromic layer 108 and the second electrochromic layer 112 are disposed at the first through hole 1084 of the display layer 106 and the second through hole 1124 of the protective layer 110, respectively. Wherein the first electrochromic layer 108 is laminated on the second electrochromic layer 112, near the cover 118 side. The first electrochromic layer 108 is defined as a colorization layer. The second electrochromic layer 112 is defined as a switching layer. As shown in fig. 3, the first electrochromic layer 108 has a patterned structure, divided into a first black matrix 1082 and a first pixel region 1080. The first black matrix 1082 and the second pixel region 1120 each have two states of coloring and discoloring. The colored state of the first black matrix 1082 is black. The first pixel region 1080 is colored in red, green, and blue according to different pixels. Wherein the boxes with the letter R represent red pixels. The box with the letter G represents a green pixel. The box with the letter B represents a blue pixel. As shown in fig. 4, fig. 4 is a sectional view taken along a-a direction in fig. 3. The first electrochromic layer 108 mainly includes a three-layer structure: the upper layer is a patterned upper electrode 1126, the middle layer is a color changing layer, and the lower electrode 1128. As shown in fig. 4, the second electrochromic layer 112 has a structure identical to that of the first electrochromic layer 108 except that the second pixel region 1120 of the second electrochromic layer 112 is colored black together with the second black matrix 1122. The second pixel region 1120 has different coloring depths with different voltages, and different coloring states have different light transmittance. The default state is that both the first electrochromic layer 108 and the second electrochromic layer 112 are colored. As shown in fig. 5, in the display mode, the micro light emitting diodes on the carrier 102 of the camera head 100 are lit and the backlight enters the human eye through the first electrochromic layer 108 and the second electrochromic layer 112. The first black matrix 1082 of the first electrochromic layer 108 and the second black matrix 1122 of the second electrochromic layer 112 are colored, and have zero transmittance, so that interference between adjacent pixels can be prevented. The first pixel region 1080 of the first electrochromic layer 108 is fully colored, and different pixels are respectively red, green and blue, and only allow light of one color to pass through, so as to filter light, for example, a red pixel, and light passing through the pixel into the human eye is red. The second pixel region 1120 of the second electrochromic layer 112 adjusts the coloring state of different pixels according to the brightness change of the display screen, thereby implementing the functions of switching and brightness adjustment of different pixels, and implementing the display function. Note that, in the plurality of second pixel regions 1120 of the second electrochromic layer 112, the voltage of each second pixel region 1120 may be different.

As shown in fig. 2, in the image capturing mode, the first black matrix 1082 and the first pixel region 1080 of the first electrochromic layer 108, and the second pixel region 1120 and the second black matrix 1122 of the second electrochromic layer 112 are all in a transparent state, and the light emitting element 104 on the lens carrier 102 of the camera head 100 is turned off, so that the light transmittance is high. The ambient light effectively enters the camera 100 from the opening area, i.e., the first through hole 1084, the second through hole 1124, and the third through hole 1140, no display element blocks the light, and the expected transmittance can be increased to more than 70%, thereby effectively improving the photographing quality. In order to reduce the light loss at the interface, transparent adhesive is filled in the corresponding opening area of the polarizer layer, namely the position of the third through hole 1140, so that the existence of an air-solid interface is effectively reduced, and the interface reflection is reduced.

As shown in fig. 5, a plurality of light emitting elements 104 are integrated on the carrier 102 of the camera head 100. A plurality of light emitting members 104 are disposed around the circumference of the camera head 100. Each light emitting member 104 has a height corresponding to the height of the carrier 102. The light emitting element 104 is partially embedded in the carrier 102, so that the increase of the Z-direction space of the mobile phone can be avoided, the backlight is provided for the display picture, and the light entering amount of the camera 100 is not affected.

The beneficial effects of this embodiment are:

1. the comprehensive screen function is realized, and the extreme experience is brought;

2. the light transmittance of the 100 area of the under-screen camera is effectively improved and can be expected to be improved to more than 70%;

3. the thickness of the whole machine is not affected, the structure is simple, and the light and thin structure is facilitated.
