[0039] An embodiment of the present application provides an electronic device, which may include a display device and a camera. The lens of the camera is arranged relative to the display device, that is, the camera obtains external light signals transmitted through the display device for imaging. It is understandable that the transmittance of a conventional display device is low, and the effect of the camera imaging through the display device is not good. To this end, the embodiment of the present application can set the display device in partitions, such as setting the transmittance of the camera portion of the display device to be greater than the transmittance of other parts of the display device, which can improve the camera imaging effect. The technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

[0040] The electronic device provided in the embodiments of the present application may be a mobile terminal device such as a mobile phone, a tablet computer, or may be a gaming device, an augmented reality (AR) device, a virtual reality (VR) device, a vehicle-mounted computer, a laptop computer, a data storage device, an audio playback device, a video playback device, a wearable device, or other device with a display device, wherein the wearable device may be a smart bracelet, smart glasses, or the like.

[0041] For ease of understanding, the following uses a mobile phone as an example. Figure 1 , Figure 1A first structural schematic diagram of an electronic device provided in an embodiment of the present application. The electronic device 10 includes a display device 20, and the display device 20 includes an adjacent first display area 220 and a second display area 240, and the light transmittance of the first display area 220 is greater than the light transmittance of the second display area 240. A camera 60 is provided in the electronic device 10, and the camera 60 includes a lens, and the lens of the camera 60 is arranged toward the first display area 220, and the camera 60 is used to obtain an external light signal passing through the first display area 220 for imaging. It can also be understood that the camera 60 is arranged below the first display area 220 of the display device 20, and the camera 60 is used to obtain an external light signal passing through the first display area 220 of the display device 20, and to form an image based on the obtained external light signal. The display area of ​​the display device 20 is complete, and there is no light-transmitting channel that cannot be displayed due to the camera 60, which improves the screen-to-body ratio of the display device 20, and can also be understood as providing a true full screen, which can display images in full screen. The camera 60 can be used as a front camera 60 of the electronic device 10 , and the camera 60 can be used to obtain images such as a user's selfie through the first display area 220 of the display device 20 .

[0042] In order to have a more comprehensive understanding of the display device of the embodiment of the present application, the display device is described in detail below.

[0043] See also Figure 2 , Figure 2 for Figure 1 The display device 20 in the embodiment of the present application may include a first display area 220 and a second display area 240 which are adjacent to each other.

[0044] Both the first display area 220 and the second display area 240 can be used to display text or images, and the first display area 220 and the second display area 240 can display the same image together. For example, the first display area 220 displays a part of the preset image, and the second display area 240 displays the remaining part of the preset image. The first display area 220 and the second display area 240 can also display different images. For example, the first display area 220 displays a taskbar image, and the second display area 240 displays a preset image. Both the first display area 220 and the second display area 240 can display content, the display area is complete, and the screen-to-body ratio of the display device 20 is high. Among them, the second display area 240 can surround the first display area 220, and the periphery of the first display area 220 can be adjacent to the second display area 240, that is, the first display area 220 is located in the middle of the second display area 240. The second display area 240 may also partially surround the first display area 220 , and a portion of the edge of the first display area 220 is adjacent to the second display area 240 . For example, the first display area 220 is located at a corner of the display device 20 or in the middle of the top of the display device 20 .

[0045] Please combine Figure 3 and Figure 4 , Figure 3 for Figure 2 The first stacking structure schematic diagram of the display device shown, Figure 4 for Figure 2 A schematic top view of a partial structure of a display device is shown.

[0046] The first display area 220 includes an anode layer 224 and a pixel layer 226 .

[0047] The pixel layer 226 includes a plurality of first pixels 2262. The first pixel 2262 is an organic light-emitting unit. The first pixel 2262 may include a plurality of sub-pixels. The first pixel 2262 may display a plurality of colors by coordinating between the plurality of sub-pixels. The first pixel 2262 may include three sub-pixels of red, green, and blue or other seed pixels. The first pixel 2262 includes different numbers of sub-pixels according to the arrangement of different sub-pixels. For example, the first pixel 2262 may include three sub-pixels of red, green, and blue or four sub-pixels of red, green, green, and blue, etc., and the number and arrangement of the sub-pixels included in the first pixel 2262 are not limited here.

[0048] The anode layer 224 is adjacent to the pixel layer 226, and the anode layer 224 includes a plurality of reflective anodes 2242, and the plurality of reflective anodes 2242 are electrically connected to the plurality of first pixels 2262, which can also be understood as each reflective anode 2242 is electrically connected to a first pixel 2262. The reflective anode 2242 can be used to drive the first pixel 2262 to emit light, and can also emit the light signal emitted by the first pixel 2262 to improve the light emission efficiency of the first display area 220. It can be understood that the emission anode is formed of an opaque material, for example, the emission anode is formed of an opaque metal material.

[0049] The first display area 220 further includes a plurality of light-transmitting wires 223 and a plurality of light-transmitting filling blocks 225. The plurality of light-transmitting wires 223 are electrically connected to the plurality of reflective anodes 2242. It can also be understood that each light-transmitting wire 223 is electrically connected to one or more reflective anodes 2242. The plurality of light-transmitting wires 223 are used to electrically connect a plurality of first driving units (not shown in the figure) disposed outside the first display area 220 and a plurality of first pixels 2262, so that each first driving unit drives one or more first pixels 2262. The plurality of light-transmitting wires 223 are disposed at intervals. Because the first driving unit includes a light-proof thin film transistor, the first driving unit driving the first pixel 2262 is disposed outside the first display area 220, so that the light transmittance of the first display area 220 can be increased. Many wirings connected to the first driving unit can also be disposed in the first display area 220 to optimize the optical properties of the first display area 220. For example, the reflection interference, refraction interference, etc. caused by the first driving unit are reduced, and at the same time, the layer structure of the first display area 220 where the first driving unit is originally arranged becomes simple, and the light transmission is more uniform.

[0050] Each light-transmitting filling block 225 is disposed between two light-transmitting wires 223 disposed at intervals, and it can also be understood that multiple light-transmitting filling blocks 225 are disposed between multiple light-transmitting wires 223 disposed at intervals, and the difference in optical parameters between the light-transmitting filling block 225 and the light-transmitting wire 223 is less than a preset parameter threshold. It can be understood that the light-transmitting wire 223 is used to transmit electrical signals, and the light-transmitting filling block 225 is filled between multiple light-transmitting wires 223 disposed at intervals, and the material of the light-transmitting filling block 225 is an insulating material.

[0051] In the first display area 220, a plurality of light-transmitting wires 223 are spaced apart and filled with light-transmitting filling blocks 225, and the difference between the optical parameters of the light-transmitting filling blocks 225 and the optical parameters of the plurality of light-transmitting wires 223 is less than a preset parameter threshold. When light passes through the layer structure where the light-transmitting wires 223 are located, part of the light passes through the light-transmitting wires 223, and part of the light passes through the light-transmitting filling blocks 225. Because the difference between the optical parameters of the light-transmitting filling blocks 225 and the light-transmitting wires 223 is less than the preset parameter threshold, the light can evenly pass through the layer structure where the light-transmitting wires 223 are located, and no diffraction effect will be generated due to the optical difference between the light-transmitting wires 223 and the filling blocks, thereby improving the light transmission effect of the display device 20. When the camera 60 acquires an image of an external light signal passing through the first display area 220, because the difference between the optical parameters of the light-transmitting wires 223 and the light-transmitting filling blocks is less than the preset parameter threshold, no diffraction effect will be generated, and a very good imaging effect can be obtained, thereby improving the image quality captured by the camera 60 through the first display area 220. It can also be understood that when light passes through the layer structure where the transparent wire 223 is located, no diffraction effect will be generated due to the optical difference between the transparent wire 223 and the filling block, so it can be considered that the difference in optical parameters between the transparent filling block 225 and the plurality of transparent wires 223 is less than the preset parameter threshold. It can be understood that the first display area 220 can be divided into a transparent area and a non-transparent area, the area corresponding to the non-transparent reflective anode 2242 is the non-transparent area, and the other areas are transparent areas. The camera 60 obtains the external light signal passing through the transparent area of ​​the first display area 220 for imaging.

[0052] The optical properties of materials are mainly refractive index and extinction coefficient. They are expressed as complex numbers n1=n+ik, where n1 is the complex refractive index, n is the ordinary refractive index, and k is the extinction coefficient.

[0053] Among them, the optical parameters of the light-transmitting wire 223 include a first refractive index and a first extinction coefficient, and the optical parameters of the light-transmitting filling block 225 include a second refractive index and a second extinction coefficient; the difference between the optical parameters of the light-transmitting filling block 225 and the light-transmitting wire 223 is less than a preset parameter threshold, which can be understood as the first refractive index and the second refractive index are equal or the difference between the first refractive index and the second refractive index is less than the preset refractive index threshold, and the first extinction coefficient and the second extinction coefficient are equal or the difference between the first extinction coefficient and the second extinction coefficient is less than the preset extinction coefficient threshold.

[0054] The material of the light-transmitting wire 223 can be indium tin oxide (ITO). ITO has good electrical conductivity and light transmittance. The transmittance of ITO in the visible light region is above 80%. By adjusting the proportion of indium oxide and the preparation process of ITO, the transmittance of ITO in the visible light region can even reach above 90%. Due to the preparation process of ITO, the microstructure of ITO, the post-processing process of ITO, the proportion of indium oxide in ITO, the proportion of tin in ITO, etc., the refractive index of ITO is between 1.5 and 2.5, and the extinction coefficient of ITO is between 0.4 and 0.8. The material of the light-transmitting wire 223 of the first display area 220 is indium tin oxide, which can have good light transmittance and good electrical conductivity. Therefore, a suitable material can be selected as the light-transmitting filling block 225 according to the first refractive index and the first extinction coefficient of ITO, that is, a material is selected whose second refractive index is equal to or less than the preset refractive index threshold value and whose second extinction coefficient is equal to or less than the preset extinction coefficient threshold value, so that the light passing through the light-transmitting filling block 225 and the light-transmitting wire 223 will not produce a diffraction effect. Among them, the preset refractive index threshold value can be set as needed, such as 0.3, 0.2 or 0.1, etc., and the preset extinction coefficient threshold value can also be set as needed, such as 0.2, 0.1 or 0.05, etc.

[0055] It is understandable that in order to improve the transmittance of the first display area 220, the transmittance of the light-transmitting filling block 225 must meet certain conditions. For example, the transmittance of the light-transmitting filling block 225 must be greater than 70%, 80% or other values. Among them, the material of the light-transmitting filling block 225 can be polycarbonate, plexiglass, polyurethane and other materials. It should be noted that the material of the light-transmitting filling block 225 is not limited to polycarbonate, plexiglass, polyurethane and other materials. As long as the difference between the optical parameters and the optical parameters of ITO is less than the preset parameter threshold, and the insulating material with higher transmittance can be used as the material of the light-transmitting filling block 225 of the embodiment of the present application, the embodiment of the present application does not limit the material of the light-transmitting filling block 225.

[0056] It should be noted that a suitable material for the light-transmitting filling block 225 can be selected within the range of a refractive index of 1.5 to 2.5 and an extinction coefficient of 0.4 to 0.8, and then the refractive index and extinction coefficient of the light-transmitting filling block 225 can be adjusted according to the refractive index and extinction coefficient of the material of the light-transmitting filling block 225 by adjusting the preparation process of ITO, the microstructure of ITO, the post-processing process of ITO, the proportion of indium oxide in ITO, the proportion of tin in ITO, etc., so that the difference between the optical parameters of ITO and the optical parameters of the light-transmitting filling block 225 is less than the preset parameter threshold, the first refractive index of ITO is equal to or less than the preset refractive index threshold, and the first extinction coefficient of ITO is equal to or less than the preset extinction coefficient threshold, so that light passing through the light-transmitting filling block 225 and the light-transmitting wire 223 will not produce a diffraction effect.

[0057] The optical parameters of the light-transmitting filling block 225 and the light-transmitting wire 223 may be the same. It should be noted that the same optical parameters of the light-transmitting filling block 225 and the light-transmitting wire 223 may also be understood as being substantially the same. In other words, as long as the light passing through the light-transmitting filling block 225 and the light-transmitting wire 223 does not produce a diffraction effect, it can be considered that the optical parameters of the light-transmitting filling block 225 and the light-transmitting wire 223 are the same, and there is no need to force the optical parameters of the light-transmitting filling block 225 and the light-transmitting wire 223 to be exactly the same.

[0058] It can be understood that the optical parameters of the light-transmitting wire 223 may include a first refractive index and a first transmittance, and the optical parameters of the light-transmitting filling block 225 include a second refractive index and a second transmittance; the optical parameters of the light-transmitting filling block 225 and the light-transmitting wire 223 being the same can be understood as the first refractive index and the second refractive index being equal or similar, and the first transmittance and the second transmittance being equal or similar.

[0059] The first display area 220 further includes a first substrate 221, which can be used as a carrier of other layer structures of the first display area 220. The first substrate 221 can be formed of materials such as glass or resin. A light-transmitting insulating layer 222 is provided between the first substrate 221 and the anode layer 224, which can also be understood as the light-transmitting insulating layer 222 being adjacent to the anode layer 224 and being disposed on the side of the anode layer 224 away from the pixel layer 226.

[0060] A plurality of light-transmitting wires 223 may be disposed on a side of the light-transmitting insulating layer 222 away from the anode layer 224. The light-transmitting insulating layer 222 has a via hole 2222. The plurality of light-transmitting wires 223 are electrically connected to a plurality of reflective anodes 2242 through a connecting wire 2224 disposed in the via hole 2222. The light-transmitting wires 223 and the reflective anodes 2242 are located on both sides of the light-transmitting insulating layer 222, and there is more space for the arrangement of the plurality of light-transmitting wires 223. In addition, the light-transmitting wires 223 may be located at the same layer or substantially horizontally with the first driving unit disposed outside the first display area 220, so as to facilitate the electrical connection between the light-transmitting wires 223 and the first driving unit.

[0061] Among them, the orthographic projection of the connecting line on the light-transmitting layer is located inside the reflective anode 2242. Considering that the emitting anode is not light-transmitting, the external light signal enters the first display area 220 and will not pass through the connecting line located below the reflective anode 2242. Even if the optical parameters of the connecting line and the surrounding light-transmitting insulating layer 222 are different, the connecting line will not affect the external light signal. Of course, the connecting line can also be set at other positions. For example, the orthographic projection of the connecting line on the light-transmitting layer is located outside the reflective anode 2242 or partially overlaps with the reflective anode 2242, and the material of the connecting line can be selected to have the same or similar optical parameters as the light-transmitting insulating layer 222.

[0062] The light-transmitting wire 223 and the light-transmitting filling block 225 are adjacent to the light-transmitting insulating layer 222 , and the light-transmitting wire 223 and the light-transmitting filling block 225 have the same thickness.

[0063] The first substrate 221 is a flat substrate, that is, the side of the first substrate 221 used for carrying other layer structures is a flat surface, the light-transmitting insulating layer 222 is arranged on the first substrate 221, and both sides of the light-transmitting insulating layer 222 are also flat surfaces, and the light-transmitting wire 223 and the light-transmitting filling block 225 are adjacent to the light-transmitting insulating layer 222, that is, the light-transmitting wire 223 and the light-transmitting filling block 225 are arranged on the light-transmitting insulating layer 222. Because the side of the light-transmitting insulating layer 222 adjacent to the light-transmitting wire 223 and the light-transmitting filling block 225 is a flat surface, if the thickness of the light-transmitting wire 223 and the light-transmitting filling block 225 is the same, then the light can pass through the light-transmitting wire 223 and the light-transmitting filling block 225 of the same thickness and the same light parameters, and no diffraction effect will be generated, and at the same time, it will not cause the thickness of different positions of other layer structures to be different, and will not cause the optical performance difference when the light signal passes through other layer structures.

[0064] It can be understood that the plurality of light-transmitting wires may be directly disposed on the first substrate, or another insulating layer may be disposed between the plurality of light-transmitting wires and the first substrate.

[0065] It should be noted that the plurality of light-transmitting wires can also be arranged at other locations. Figure 5 , Figure 5 for Figure 2 The second stacked structure schematic diagram of the display device is shown. Multiple light-transmitting wires 223 can also be arranged in the anode layer 224, that is, in the same layer as the reflective anode 2242. The multiple light-transmitting wires 223 and the multiple reflective anodes 2242 are arranged at intervals. The light-transmitting wires 223 and the reflective anodes 2242 are more convenient to be electrically connected, and there is no need to set a via connection. At the same time, the light-transmitting insulating layer 222 can be arranged between the anode layer 224 and the first substrate 221, that is, only one light-transmitting insulating layer 222 is needed between the first substrate 221 and the anode layer 224. The overall layer structure of the first display area 220 is simple and easy to manufacture.

[0066] Similarly, the first substrate 221 is a flat substrate, that is, the side of the first substrate 221 used to carry other layer structures is a flat surface, the light-transmitting insulating layer 222 is arranged on the first substrate 221, and both sides of the light-transmitting insulating layer 222 are also flat surfaces, and the anode layer 224 is adjacent to the light-transmitting insulating layer 222, that is, the light-transmitting wire 223, the light-transmitting filling block 225 and the reflective anode 2242 are all arranged on the light-transmitting insulating layer 222. Because the side of the light-transmitting insulating layer 222 adjacent to the transparent anode layer 224 is a flat surface, if the thickness of the light-transmitting wire 223 and the light-transmitting filling block 225 is the same, then the light can pass through the light-transmitting wire 223 and the light-transmitting filling block 225 of the same thickness and the same light parameters, and no diffraction effect will be generated. At the same time, it will not cause different thicknesses at different positions of other layer structures, and will not cause optical performance differences when the light signal passes through other layer structures. In addition, the thicknesses of the light-transmitting conductive wire 223 , the light-transmitting filling block 225 and the reflective anode 2242 are the same, so that other layer structures on the anode layer 224 , such as the pixel layer 226 , can be easily arranged.

[0067] The first pixel 2262 is made of organic material, and the first pixel 2262 has good light transmittance, that is, the external light signal can pass through the first pixel 2262. If the first pixel 2262 and the reflective anode 2242 are staggered, the light transmittance of the first display area 220 is not greatly affected. However, in order to improve the display brightness of the first display area 220, the reflective anode 2242 can be set directly below the first pixel 2262, and the size is greater than or equal to the first pixel 2262. It can also be understood that the positive projection of each first pixel 2262 in the anode layer 224 is located in a reflective anode 2242, so that the light signal emitted by the first pixel 2262 is emitted as much as possible to obtain a better display brightness. In addition, the first pixel 2262 includes a plurality of sub-pixels of different colors, and the optical parameters of the sub-pixels of different colors are different. If the camera 60 obtains the external light signal through the first pixel 2262 for imaging, it is difficult to process the light signal through the sub-pixels of different colors, and the light signal that does not pass through the first pixel 2262 must also be processed. Therefore, the orthographic projection of each first pixel 2262 in the anode layer 224 is located within a reflective anode 2242 , which can improve the uniformity of light passing through the first display area 220 and improve the quality of imaging through the first display area 220 .

[0068] The second display area includes a plurality of second pixels, and the distribution density of the plurality of second pixels is greater than the distribution density of the plurality of first pixels. Figure 6 , Figure 6 for Figure 2 The first enlarged schematic diagram of the X portion is shown. The size of the second pixel 242 can be the same as the size of the first pixel 2262. The spacing between the first pixels 2262 of the first display area 220 is large, which can improve the light transmittance of the first display area 220. For example, the distribution density of the first pixels 2262 of the first display area 220 is 200ppi, and the distribution density of the second pixels 242 of the second display area 240 can reach more than 400ppi. In another example, please refer to Figure 7 , Figure 7 for Figure 2 The second enlarged schematic diagram of the X portion is shown. The size of the first pixel 2262 of the first display area 220 can be larger than the size of the second pixel 242 of the second display area 240, and the spacing between the first pixels 2262 is positively correlated with the size of the first pixel 2262, that is, the larger the size of the first pixel 2262, the larger the spacing between the first pixels 2262, therefore, the distribution density of the first pixels 2262 of the first display area 220 is greater than the distribution density of the second pixels 242 of the second display area 240.

[0069] It can be understood that the distribution density of the first pixels in the first display area is smaller than the distribution density of the second pixels in the second display area. The smaller the distribution density of the first pixels, the larger the proportion of the area with higher light transmittance between the first pixels, so that the light transmittance of the first display area is greater than the light transmittance of the second display area. In addition, the first driving unit driving the first display area is arranged in the first display area, and the second driving unit driving the second pixels is arranged in the second display area, so that the light transmittance of the first display area is greater than the light transmittance of the second display area.

[0070] See also Figure 8 , Figure 8 for Figure 2 The display device 20 further includes a non-display area 260, such as an edge of the display device 20. The first driving unit 2264 disposed outside the first display area 220 can be disposed in the non-display area 260, which can improve the light transmittance of the first display area 220 without affecting the second display area 240.

[0071] See also Fig. 9 , Fig. 9 for Figure 2 A third enlarged schematic diagram of portion X is shown.

[0072] The first driving unit 2264 disposed outside the first display area 220 may also be disposed in the second display area 240. For example, each first driving unit 2264 is disposed between a plurality of second driving units. The first driving unit 2264 may be better disposed in the second display, and the first driving unit 2264 may adopt a simple driving circuit. For example, the first driving unit 2264 may adopt a 2T1C or 5T1C driving circuit, and the second driving unit may adopt a 7T1C driving circuit, thereby obtaining a better driving effect.

[0073] In some embodiments, the first pixel of the first display area and the second pixel of the second display area have the same size, but in order to reduce the number of TFTs in the first driving unit driving the first pixel of the first display area, multiple first display areas can be arranged in parallel, thereby reducing the number of TFTs in the first driving unit, and facilitating the first driving unit to be arranged in the second display area. The second display area may include a transition area, the transition area is adjacent to the first display area, and multiple second pixels in the transition area are arranged in parallel. One second driving unit in the transition area can drive the multiple parallel second pixels, thereby freeing up some space, and the freed up space can be used to set the first driving unit.

[0074] The present application also provides a display device. The main difference between the display device in this embodiment and the display device in the above embodiment is the light-transmitting filling block. Figures 1 to 9In the embodiment of the present application, the display device 20 includes a first display area 220 and a second display area 240 adjacent to each other, the transmittance of the first display area 220 is greater than the transmittance of the second display area 240, and the first display area 220 includes a pixel layer 226, an anode layer 224, a light-transmitting insulating layer 222, a plurality of light-transmitting wires 223 and a plurality of light-transmitting filling blocks 225.

[0075] The pixel layer 226 includes a plurality of first pixels 2262. The structure of the pixel layer 226 can refer to the structure of the pixel layer 226 in any of the above embodiments, which will not be described in detail here.

[0076] The anode layer 224 is adjacent to the pixel layer 226. The anode layer 224 includes a plurality of reflective anodes 2242. The plurality of reflective anodes 2242 are electrically connected to a plurality of first pixels 2262. It can also be understood that each reflective anode 2242 is electrically connected to a first pixel 2262. The structure of the anode layer 224 can refer to the structure of the anode layer 224 in any of the above embodiments, and will not be repeated here.

[0077] The light-transmitting insulating layer 222 is disposed on the side of the anode layer 224 away from the pixel layer 226. The structure of the light-transmitting insulating layer 222 can refer to the structure of the light-transmitting insulating layer 222 in any of the above embodiments, which will not be described in detail here.

[0078] The plurality of light-transmitting wires 223 are electrically connected to the plurality of reflective anodes 2242, which can also be understood as each light-transmitting wire 223 being electrically connected to one or more reflective anodes 2242. The plurality of light-transmitting wires 223 are used to electrically connect the plurality of first driving units 2264 and the plurality of first pixels 2262 disposed outside the first display area 220, so that each first driving unit 2264 drives one or more first pixels 2262, and the plurality of light-transmitting wires 223 are disposed at intervals. The structure of the light-transmitting wire 223 can refer to the structure of the light-transmitting wire 223 in any of the above-mentioned embodiments, and will not be described in detail here.

[0079] Each light-transmitting filling block 225 is arranged between two spaced light-transmitting wires 223 . It can also be understood that multiple light-transmitting filling blocks 225 are arranged between multiple spaced light-transmitting wires 223 , and the difference in optical parameters between the light-transmitting filling block 225 and the light-transmitting wire 223 is smaller than the difference in optical parameters between the light-transmitting insulating layer 222 and the light-transmitting wire 223 .

[0080] In the related art, the light-transmitting wire is arranged in the groove of the light-transmitting insulating layer, the optical parameters between the light-transmitting wire and the light-transmitting insulating layer are quite different, the light-transmitting wire is densely and irregularly arranged, and the light will produce a diffraction effect when passing through the light-transmitting wire and the light-transmitting insulating layer. At the same time, due to the complex routing of the light-transmitting wire, the diffraction effect caused is irregular, and it is more difficult to perform compensation algorithms at the back end, more computing resources are consumed, and it is also difficult to completely solve the diffraction effect, which has a relatively large impact on the performance of photography and mobile phones. In the embodiment of the present application, the light-transmitting wire 223 is not arranged in the groove of the light-transmitting insulating layer 222, but a light-transmitting filling block 225 is filled in the light-transmitting wire 223 arranged at intervals, and the difference in optical parameters between the light-transmitting filling block 225 and the light-transmitting wire 223 is less than the difference in optical parameters between the light-transmitting insulating layer 222 and the light-transmitting wire 223, which can improve the diffraction effect when the light passes through the layer structure where the light-transmitting wire 223 is located.

[0081] Among them, the optical parameters of the light-transmitting wire 223 include a first refractive index and a first extinction coefficient, the optical parameters of the light-transmitting filling block 225 include a second refractive index and a second extinction coefficient, and the optical parameters of the light-transmitting insulating layer 222 include a third refractive index and a third extinction coefficient; the difference between the first refractive index and the second refractive index is smaller than the difference between the first refractive index and the third refractive index, and the difference between the first extinction coefficient and the second extinction coefficient is smaller than the difference between the first extinction coefficient and the third extinction coefficient.

[0082] The material of the light-transmitting wire 223 can be indium tin oxide (ITO). ITO has good electrical conductivity and light transmittance. The transmittance of ITO in the visible light region is above 80%. By adjusting the proportion of indium oxide and the preparation process of ITO, the transmittance of ITO in the visible light region can even reach above 90%. Due to the preparation process of ITO, the microstructure of ITO, the post-processing process of ITO, the proportion of indium oxide in ITO, the proportion of tin in ITO, etc., the refractive index of ITO is between 1.5 and 2.5, and the extinction coefficient of ITO is between 0.4 and 0.8. The material of the light-transmitting wire 223 of the first display area 220 is indium tin oxide, which can have good light transmittance and good electrical conductivity. The material of the light-transmitting insulating layer 222 can be resin, etc., whose refractive index is between 1.49 and 1.74, and whose extinction coefficient is between 0.6 and 1.0. It is difficult for both the refractive index and the extinction coefficient to be the same or similar to those of ITO. It should be noted that the material of the light-transmitting insulating layer 222 may also be other materials, such as polyimide, etc. Therefore, according to the first refractive index and the first extinction coefficient of ITO, and the third refractive index and the third extinction coefficient of the transparent insulating layer, a suitable material may be selected as the light-transmitting filling block 225, that is, the difference between the first refractive index and the second refractive index is smaller than the difference between the first refractive index and the third refractive index, and the difference between the first extinction coefficient and the second extinction coefficient is smaller than the difference between the first extinction coefficient and the third extinction coefficient, thereby improving the diffraction effect of light passing through the layer structure where the light-transmitting wire 223 is located.

[0083] In order to better improve the diffraction effect of light passing through the layer structure where the light-transmitting wire 223 is located, the second refractive index of the light-transmitting filling block 225 is equal to the first refractive index of the light-transmitting wire 223, and the second extinction coefficient of the light-transmitting filling block 225 is equal to the first extinction coefficient of the light-transmitting wire 223. Thus, the diffraction effect of light passing through the layer structure where the light-transmitting wire 223 is located is eliminated.

[0084] It is understandable that in order to improve the transmittance of the first display area 220, the transmittance of the light-transmitting filling block 225 must meet certain conditions. For example, the transmittance of the light-transmitting filling block 225 must be greater than 70%, 80% or other values. Among them, the material of the light-transmitting filling block 225 can be polycarbonate, organic glass, polyurethane and other materials. It should be noted that the material of the light-transmitting filling block 225 is not limited to polycarbonate, organic glass, polyurethane and other materials. As long as the optical parameters are the same as the optical parameters of ITO and the insulating material with higher transmittance can be used as the material of the light-transmitting filling block 225 of the embodiment of the present application, the embodiment of the present application does not limit the material of the light-transmitting filling block 225.

[0085] It should be noted that a suitable material for the light-transmitting filling block 225 can be selected within the range of a refractive index of 1.5 to 2.5 and an extinction coefficient of 0.4 to 0.8, and then the refractive index and extinction coefficient of the light-transmitting filling block 225 can be adjusted according to the refractive index and extinction coefficient of the material of the light-transmitting filling block 225 by adjusting the preparation process of ITO, the microstructure of ITO, the post-processing process of ITO, the proportion of indium oxide in ITO, the proportion of tin in ITO, etc., so that the optical parameters of ITO are the same as those of the light-transmitting filling block 225, even if the first refractive index of ITO is equal to or similar to the second refractive index of the light-transmitting filling block 225, and the first extinction coefficient of ITO is equal to or similar to the second extinction coefficient of the light-transmitting filling block 225, so that light passing through the light-transmitting filling block 225 and the light-transmitting wire 223 will not produce a diffraction effect.

[0086] The first display area 220 further includes a first substrate 221, which can be used as a carrier of other layer structures of the first display area 220. The first substrate 221 can be formed of materials such as glass or resin. A light-transmitting insulating layer 222 is provided between the first substrate 221 and the anode layer 224, which can also be understood as the light-transmitting insulating layer 222 being adjacent to the anode layer 224 and being disposed on the side of the anode layer 224 away from the pixel layer 226.

[0087] A plurality of light-transmitting wires 223 may be disposed on a side of the light-transmitting insulating layer 222 away from the anode layer 224. The light-transmitting insulating layer 222 has a via hole, and the plurality of light-transmitting wires 223 are electrically connected to the plurality of reflective anodes 2242 through connecting wires disposed in the via hole. The light-transmitting wires 223 and the reflective anodes 2242 are located on both sides of the light-transmitting insulating layer 222, and there is more space for the arrangement of the plurality of light-transmitting wires 223. In addition, the light-transmitting wires 223 may be located at the same layer or substantially horizontally with the first driving unit 2264 disposed outside the first display area 220, so as to facilitate the electrical connection between the light-transmitting wires 223 and the first driving unit 2264.

[0088] Among them, the orthographic projection of the connecting line on the light-transmitting layer is located inside the reflective anode 2242. Considering that the reflective anode is not light-transmitting, the external light signal enters the first display area 220 and will not pass through the connecting line located below the reflective anode 2242. Even if the optical parameters of the connecting line and the surrounding light-transmitting insulating layer 222 are different, the connecting line will not affect the external light signal. Of course, the connecting line can also be set at other positions. For example, the orthographic projection of the connecting line on the light-transmitting layer is located outside the reflective anode 2242 or partially overlaps with the reflective anode 2242, and the material of the connecting line can be selected to have the same or similar optical parameters as the light-transmitting insulating layer 222.

[0089] The light-transmitting wire 223 and the light-transmitting filling block 225 are both disposed on the light-transmitting insulating layer 222 , and the light-transmitting wire 223 and the light-transmitting filling block 225 have the same thickness.

[0090] The first substrate 221 is a flat substrate, that is, the side of the first substrate 221 used for carrying other layer structures is a flat surface, the light-transmitting insulating layer 222 is arranged on the first substrate 221, and both sides of the light-transmitting insulating layer 222 are also flat surfaces, and the light-transmitting wire 223 and the light-transmitting filling block 225 are adjacent to the light-transmitting insulating layer 222, that is, the light-transmitting wire 223 and the light-transmitting filling block 225 are arranged on the light-transmitting insulating layer 222. Because the side of the light-transmitting insulating layer 222 adjacent to the light-transmitting wire 223 and the light-transmitting filling block 225 is a flat surface, if the thickness of the light-transmitting wire 223 and the light-transmitting filling block 225 is the same, then the light can pass through the light-transmitting wire 223 and the light-transmitting filling block 225 of the same thickness and the same light parameters, and no diffraction effect will be generated, and at the same time, it will not cause the thickness of different positions of other layer structures to be different, and will not cause the optical performance difference when the light signal passes through other layer structures.

[0091] It is understandable that the plurality of light-transmitting wires 223 may be directly disposed on the first substrate 221 , or another insulating layer may be disposed between the plurality of light-transmitting wires 223 and the first substrate 221 .

[0092] It should be noted that the plurality of light-transmitting wires 223 can also be arranged on the anode layer 224, that is, in the same layer as the reflective anode 2242, and the plurality of light-transmitting wires 223 and the plurality of reflective anodes 2242 are arranged at intervals, and the light-transmitting wires 223 and the reflective anode 2242 are more convenient to be electrically connected, and there is no need to set a via connection. At the same time, the light-transmitting insulating layer 222 can be arranged between the anode layer 224 and the first substrate 221, that is, only one light-transmitting insulating layer 222 is required between the first substrate 221 and the anode layer 224, and the overall layer structure of the first display area 220 is simple and convenient to manufacture.

[0093] Similarly, the first substrate 221 is a flat substrate, that is, the side of the first substrate 221 used to carry other layer structures is a flat surface, the light-transmitting insulating layer 222 is arranged on the first substrate 221, and both sides of the light-transmitting insulating layer 222 are also flat surfaces, and the anode layer 224 is adjacent to the light-transmitting insulating layer 222, that is, the light-transmitting wire 223, the light-transmitting filling block 225 and the reflective anode 2242 are all arranged on the light-transmitting insulating layer 222. Because the side of the light-transmitting insulating layer 222 adjacent to the transparent anode layer 224 is a flat surface, if the thickness of the light-transmitting wire 223 and the light-transmitting filling block 225 is the same, then the light can pass through the light-transmitting wire 223 and the light-transmitting filling block 225 of the same thickness and the same light parameters, and no diffraction effect will be generated. At the same time, it will not cause different thicknesses at different positions of other layer structures, and will not cause optical performance differences when the light signal passes through other layer structures. In addition, the thicknesses of the light-transmitting conductive wire 223 , the light-transmitting filling block 225 and the reflective anode 2242 are the same, so that other layer structures on the anode layer 224 , such as the pixel layer 226 , can be easily arranged.

[0094] The orthographic projection of each first pixel 2262 on the anode layer 224 is located inside a reflective anode 2242. The structures of the first pixel 2262, the anode layer 224, and the reflective anode 2242 can refer to the structures of any of the above embodiments, and will not be described in detail herein.

[0095] It can be understood that the display device 20 further includes a non-display area 260, and the first drive unit 2264 can be disposed in the non-display area 260, and the first drive unit 2264 can also be disposed in the second display area 240. The structure and position of the first drive unit 2264, and the structure and position of the second drive unit can adopt the structure and position of the first drive unit 2264, and the structure and position of the second drive unit in any of the above embodiments, and will not be repeated here.

[0096] The second display area 240 includes a plurality of second pixels 242, and the distribution density of the plurality of second pixels 242 is greater than the distribution density of the plurality of first pixels 2262. The structure and distribution mode of the first pixels 2262 and the structure and distribution mode of the second pixels 242 can adopt the structure and distribution mode of the first pixels 2262 and the structure and distribution mode of the second pixels 242 in any of the above embodiments, and will not be described in detail here.

[0097] It should be noted that the first display area 220 includes a first substrate 221, a light-transmitting insulating layer 222, an anode layer 224, a pixel layer 226, a common electrode layer, and a second substrate, which are sequentially arranged. The first substrate 221 is adjacent to the light-transmitting insulating layer 222 and is located on the side of the light-transmitting insulating layer 222 away from the pixel layer 226, the common electrode layer is adjacent to the pixel layer 226 and is located on the side of the pixel layer 226 away from the first substrate 221, and the second substrate is adjacent to the common electrode layer and is located on the side of the common electrode layer away from the pixel layer 226. The common electrode layer and the emission anode are used to jointly drive the first pixel 2262 of the pixel layer 226 to display, and the first driving unit 2264 driving the first pixel 2262 is arranged outside the first display area 220, which can improve the light transmittance of the first display area 220, and the layer structure of the first display area 220 is simple, which facilitates the uniform light transmission of the first display area 220.

[0098] The present application also provides a display device. The main difference between the display device in this embodiment and the display device in the above embodiment is the first driving unit. Figures 1 to 9 In the embodiment of the present application, the display device 20 includes a first display area 220 and a second display area 240 adjacent to each other, and the light transmittance of the first display area 220 is greater than the light transmittance of the second display area 240. The first display area 220 includes a pixel layer 226, an anode layer 224, a plurality of first driving units 2264, a plurality of light-transmitting wires 223, and a plurality of light-transmitting filling blocks 225.

[0099] The pixel layer 226 includes a plurality of first pixels 2262. The structure of the pixel layer 226 can refer to the structure of the pixel layer 226 in any of the above embodiments, which will not be described in detail here.

[0100] The anode layer 224 is adjacent to the pixel layer 226. The anode layer 224 includes a plurality of reflective anodes 2242. The plurality of reflective anodes 2242 are electrically connected to the plurality of first pixels 2262 in a one-to-one correspondence. It can also be understood that each reflective anode 2242 is electrically connected to a first pixel 2262. The structure of the anode layer 224 can refer to the structure of the anode layer 224 in any of the above embodiments, and will not be repeated here.

[0101] Each first driving unit 2264 is electrically connected to one or more reflective anodes 2242 , and drives the first pixel 2262 via the reflective anode 2242 . The projection of each first driving unit 2264 on the anode layer 224 is located within a reflective anode 2242 .

[0102] Each transparent wire 223 is electrically connected to the first driving unit 2264, and a plurality of transparent wires 223 are arranged at intervals. The structure of the transparent wire 223 can refer to the structure of the transparent wire 223 in any of the above embodiments, and will not be described again.

[0103] Each transparent filling block 225 is arranged between two spaced transparent wires 223, and the difference between the optical parameters of the transparent filling block 225 and the transparent wire 223 is less than the preset parameter threshold. The optical properties of the material are mainly the refractive index and the extinction coefficient. It is represented by a complex number n1=n+ik, where n1 is the complex refractive index, n is the ordinary refractive index, and k is the extinction coefficient. Among them, the optical parameters of the transparent wire 223 include a first refractive index and a first extinction coefficient, and the optical parameters of the transparent filling block 225 include a second refractive index and a second extinction coefficient; the difference between the optical parameters of the transparent filling block 225 and the transparent wire 223 is less than the preset parameter threshold, which can be understood as the first refractive index and the second refractive index are equal or the difference between the first refractive index and the second refractive index is less than the preset refractive index threshold, and the first extinction coefficient and the second extinction coefficient are equal or the difference between the first extinction coefficient and the second extinction coefficient is less than the preset extinction coefficient threshold. The structure of the transparent wire 223 can refer to the structure of the transparent wire in any of the above embodiments, and will not be repeated here. The structure of the light-transmitting filling block 225 can refer to the structure of the light-transmitting filling block 225 in any of the above embodiments, and will not be described in detail here. The preset refractive index threshold can be set as needed, such as 0.3, 0.2 or 0.1, and the preset extinction coefficient threshold can also be set as needed, such as 0.2, 0.1 or 0.05.

[0104] The first driving unit 2264 driving the first pixel 2262 may also be arranged in the first display area 220, but in order not to affect the optical characteristics of the first display area 220, the first driving unit 2264 is arranged below the reflective anode 2242, that is, the projection of the first driving unit 2264 on the anode layer 224 is located inside the reflective anode 2242, because the reflective anode 2242 is opaque, the external light signal cannot irradiate the first driving unit 2264, and the first driving unit 2264 will not generate refraction interference, reflection interference, etc. It should be noted that the light-transmitting wire 223 in this embodiment can electrically connect the driving chip driving the first display area 220 and the first driving unit 2264, the first display area 220 may include a layer structure such as a driving circuit layer, the first driving unit 2264 is arranged in the driving circuit layer, the light-transmitting wire 223 can be arranged in the driving circuit layer, the connecting wire electrically connecting the first driving unit 2264 and the emission anode can be arranged below the reflective anode, and the structure of the connecting wire can adopt the same structure as the transparent wire, or can adopt other structures, such as an opaque structure, etc.

[0105] It should be noted that the structure of the first pixel 2262 and the like in this embodiment may adopt the corresponding structure in any of the above embodiments, which will not be described in detail here.

[0106] See also Fig.10 , Fig.10 for Figure 2 The third stacked structure schematic diagram of the display device shown. The first display area 220 includes a first substrate 221, a light-transmitting insulating layer 222, an anode layer 224, a pixel layer 226, a common electrode layer 228 and a second substrate 229 which are arranged in sequence. Among them, the first substrate 221 is adjacent to the light-transmitting insulating layer 222 and is located on the side of the light-transmitting insulating layer 222 away from the pixel layer 226, the common electrode layer 228 is adjacent to the pixel layer 226 and is located on the side of the pixel layer 226 away from the first substrate 221, and the second substrate 229 is adjacent to the common electrode layer 228 and is located on the side of the common electrode layer 228 away from the pixel layer 226. The common electrode layer 228 and the reflective anode are used to jointly drive the first pixel display of the pixel layer 226. The first driving unit driving the first pixel is arranged outside the first display area 220, which can improve the light transmittance of the first display area 220, and the layer structure of the first display area 220 is simple, which facilitates the uniform light transmission of the first display area 220. In some embodiments, part of the layer structure may be adjusted as needed. For example, the second substrate may not be provided in the first display area.

[0107] It can be understood that the light-transmitting wires and the light-transmitting filling blocks can be arranged between the pixel layer and the first substrate. The embodiments of the present application do not limit the specific positions of the light-transmitting wires and the light-transmitting filling blocks. For example, the light-transmitting wires and the light-transmitting filling blocks can be arranged in the anode layer, or can be arranged between the light-transmitting insulating layer and the first substrate.

[0108] The lens of the camera in the electronic device faces the first substrate of the display device, and the camera is used to obtain external light signals passing through the first display area for imaging. In order to reduce the space occupied by the camera, the lens of the camera can be close to or adjacent to the first substrate of the display device. The first substrate of the display device is mainly used to support other layer structures of the display device and does not need any special functions. Therefore, in order to further reduce the space occupied by the camera, the camera part can be set inside the first substrate. For details, please refer to Fig.11 , Fig.11 The first structural schematic diagram of the display device and the camera provided in the embodiment of the present application. A first mounting hole 2912 is set at the position of the first substrate relative to the camera 60, and the camera 60 is at least partially set in the first mounting hole 2912. The first mounting hole 2912 can be a blind hole, that is, the thickness of the part of the first substrate 291 relative to the camera 60 is less than the thickness of other parts, and the first substrate 291 is still a complete substrate 291, which does not affect its function of carrying other layer structures of the display device 20, and can vacate some space to accommodate the camera 60. The installation method of the first mounting hole 2912 and the camera 60 can be set according to the size of the first mounting hole 2912 and the size of the camera 60. Exemplarily, if the space of the first mounting hole 2912 is not enough to install the entire camera 60, the lens 62 of the camera 60 is partially set in the first mounting hole 2912. If the camera 60 is small enough, the entire camera 60 is set in the first mounting hole 2912.

[0109] Because the first display area does not need to be provided with the first driving unit, the layer structure of the first display area is simple and does not have a complicated circuit, and the camera can be installed in other layer structures of the first display area such as the light-transmitting insulating layer. Fig.12 , Fig.12 A second structural schematic diagram of a display device and a camera provided in an embodiment of the present application. The first mounting hole 2912 is a through hole, and the light-transmitting insulating layer of the first display area has a second mounting hole 2922 relative to the camera 60. The first mounting hole 2912 and the second mounting hole 2922 are connected, and the camera 60 can be at least partially located in the second mounting hole 2922. For example, the lens 62 of the camera 60 is located in the first mounting hole 2912 and the second mounting hole 2922. The second mounting hole 2922 can be a through hole or a blind hole. The first mounting hole 2912 and the second mounting hole 2922 can be made after the partial stacking structure of the display device 20 is formed. For example, after the light-transmitting insulating layer, anode layer, pixel layer, and common electrode layer of the display device 20 are all arranged on the substrate 291, the first mounting hole 2912 and the second mounting hole 2922 are made corresponding to the position of the lens 62 of the camera 60 by laser or the like.

[0110] It should be noted that the camera 60 relative to the first display area can be used as the front camera 60 of the electronic device. The front camera is generally a camera whose lens cannot be moved. The substrate 291 and the light-transmitting insulating layer of the display device can be provided with a first mounting hole 2912 and a second mounting hole 2922. Then, the camera 60 relative to the first display area can be a camera 60 with a movable lens 62. The movable lens 62 of the camera 60 is used to realize functions such as autofocus.

[0111] One camera or multiple cameras may be arranged below the first display area. The multiple cameras may be cameras that cooperate with each other, such as two identical cameras, a normal camera and a blur camera or a black and white camera, etc. In addition to the camera, other functional devices may be arranged below the first display area, such as a proximity sensor, a light sensor, a distance sensor, a fingerprint recognition sensor, etc.

[0112] It is understood that in any of the above embodiments, the size and shape of the first pixel in the first display area can be set as needed. For example, the first pixel can be rectangular or quasi-circular. The quasi-circular first pixel can be circular, elliptical or rounded rectangular. The quasi-circular first pixel can improve the diffraction problem of the first display area because the edge is an arc transition.

[0113] The display device may be in a regular shape, such as a rectangle, a rounded rectangle or a circle. Of course, in some other possible embodiments, the display device may also be in an irregular shape, which is not limited in the embodiments of the present application.
