[0030] An embodiment of the present application provides an electronic device and a display device thereof. The electronic device 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 conventional display devices is low, and the imaging effect of the camera 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 part of the display device to be greater than the transmittance of other positions 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.

[0031] 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.

[0032] See also Figure 1 , Figure 1A first structural schematic diagram of an electronic device provided in an embodiment of the present application. Figure 1 An example in which the electronic device 10 is a mobile phone is shown. Among them, the electronic device 10 includes a display device 20. The display device 20 includes a first display area 240 and a second display area 220, and the transmittance of the first display area 240 is greater than the transmittance of the second display area 220. A camera 60 is provided in the electronic device 10, and the lens of the camera 60 is arranged toward the first display area 240, and the camera 60 is used to obtain an external light signal passing through the first display area 240 for imaging. It can also be understood that the camera 60 is arranged below the first display area 240 of the display device 20, and the camera 60 is used to obtain an external light signal passing through the first display area 240 of the display device 20, and to form an image based on the obtained external light signal. The first display area 240 can be displayed normally when the camera 60 is not working, so there is no need to open a hole in the display device 20 or reserve a non-display area to set the camera, and the display area of ​​the display device 20 is complete, which improves the screen ratio of the display device 20. The camera 60 can be used as a front camera of the electronic device, and the camera 60 can be used to obtain images such as selfies of the user through the first display area 240 of the display device 20.

[0033] 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.

[0034] See also Figure 2 , Figure 2 A first structural schematic diagram of a display device provided in an embodiment of the present application. The display device 20 in the embodiment of the present application may include a first display area 240 and a second display area 220 adjacent to each other. Both the second display area 220 and the first display area 240 may be used to display text or images, and the second display area 220 and the first display area 240 may display the same image together, for example, the second display area 220 displays a portion of a preset image, and the first display area 240 displays the remaining portion of the preset image. The second display area 220 and the first display area 240 may also display different images, for example, the second display area 220 displays a preset image, and the first display area 240 displays a taskbar image. The second display area 220 may at least partially surround the first display area 240. It is understood that the periphery of the first display area 240 may all be adjacent to the second display area 220, or a portion of the periphery of the first display area 240 may be adjacent to the second display area 220. For example, the first display area 240 may be located at a corner of the display device 20 or in the middle of the top of the display device 20.

[0035] See also Figure 3 , Figure 3The first display area of ​​the display device includes a driving circuit layer 292, an anode layer 293, a light emitting layer 294, and a common electrode layer 295 which are stacked in sequence.

[0036] The driving circuit layer 292 includes a plurality of first driving units 248, and the plurality of first driving units 248 are used to drive the light emitting layer 294. The first driving unit 248 includes a light-proof portion such as a thin film transistor TFT.

[0037] The anode layer 293 may be entirely or partially disposed on the driving circuit layer 292 . The anode layer 293 is connected to the driving circuit layer 292 and is used to control each first driving unit 248 of the driving circuit layer 292 .

[0038] The light emitting layer 294 is disposed on the anode layer 293 . The light emitting layer 294 includes a pixel definition layer 2942 . The pixel definition layer 2942 has a plurality of pixel holes. A first pixel 246 is disposed in each pixel hole. The first pixel 246 includes an organic light emitting material.

[0039] The common electrode layer 295 is disposed on the light emitting layer 294 . The anode layer 293 and the common electrode layer 295 are respectively disposed on both sides of the first pixel 246 , and drive the first pixels 246 together with the first driving units 248 of the driving circuit layer 292 .

[0040] During the imaging process of the camera acquiring the external light signal through the first display area 240, because the first driving unit 248 of the driving circuit layer 292 located in the first display area 240 includes an opaque part such as a thin film transistor, the external light signal will produce stray light reflected and refracted after being irradiated to the first driving unit 248, thereby affecting the imaging effect of the camera. In the embodiment of the present application, a light shielding block 280 is arranged between the first driving unit 292 and the light-emitting layer 294, and the light shielding block 280 is at least partially arranged opposite to the first driving unit 248. It can also be understood that the positive projection of the light shielding block 280 on the driving circuit layer 292 overlaps with the first driving unit 248 at least partially. The light shielding block 280 can be used to shield the external light signal irradiated to the first driving unit 248, reducing the stray light interference caused by the reflection and refraction of the first driving unit 248. When the camera acquires the external light signal through the first display area for imaging, the light shielding block 280 can reduce the stray light interference and improve the imaging quality of the camera. Among them, the light shielding block 280 can be a black light-absorbing material. The shape, size, and arrangement of the light shielding block 280 may be set according to the first driving unit 248 .

[0041] Exemplarily, the orthographic projection of the light shielding block 280 on the driving circuit layer 292 can cover the first driving unit 248. That is, the size of the light shielding block 280 is greater than or equal to the size of the first driving unit 248, and the light shielding block 280 is directly above the first driving unit 248. It can also be understood that when the external light signal enters the first display area in a direction perpendicular to the first display area, the light shielding block 280 just blocks the external light signal from irradiating the first driving unit 248. The size of the light shielding block 280 can be slightly larger than the size of the first driving unit 248, which can better block the external light signal irradiating the first driving unit 248 and minimize the stray light interference caused by the first driving unit 248. The light shielding block 280 can correspond to the first driving unit 248 one by one and be relatively arranged, such as Figure 4 As shown. It is understandable that Figure 4 Schematic diagram of the distribution of the light shielding blocks 280 in the first display area is shown in FIG. 1 , and a first driving unit shielded by the light shielding block 280 is disposed under each light shielding block 280 .

[0042] Combination Figure 5 , Figure 5 for Figure 2 The first enlarged schematic diagram of the X part in the middle. The first pixels 246 are arranged regularly, and the external light signal will generate diffraction light in the process of passing through the regularly arranged multiple first pixels 246 to reach the camera located below the first display area 240, thereby affecting the imaging quality of the camera. Among them, regular arrangement means that the multiple first pixels 246 have a periodic arrangement rule in at least one arrangement direction. In order to improve the imaging quality of the camera, it is necessary to deal with the diffraction interference caused by the above-mentioned diffraction light in the imaging in the later stage. Since the diffraction light generated by the light passing through the regularly arranged first pixels 246 will generate periodic diffraction interference, and this periodic diffraction interference can be obtained according to the incident angle of the light and the size, spacing, arrangement period and other parameters of the first pixels 246, the periodic diffraction interference can be removed by later image processing.

[0043] It can be understood that, since the first driving units 248 correspond one-to-one to the first pixels 246, the first driving units 248 are also regularly arranged, and accordingly, the light shielding blocks 280 corresponding one-to-one to the first driving units 248 are also regularly arranged. Therefore, the regularly arranged light shielding blocks 280 will also generate diffraction interference to the light incident on the camera 60.

[0044] If the light shielding block 280 is arranged relative to the first pixel 246 part, a complex diffraction problem will occur. Specifically, for ease of understanding, the following is an example of an external light signal that vertically illuminates the first display area 240. The external light signal includes a first part of the external light signal and a second part of the external light signal. The first part of the external light signal is irradiated on the first pixel 246 to generate a first diffraction light signal. After the first part of the external light signal passes through the first pixel 246, it is irradiated on the light shielding block 280 together with the first diffraction light signal to generate a second diffraction light signal. The second part of the external light signal irradiates the pixel definition layer 2942 between the multiple first pixels 246 and does not generate the first diffraction light signal. After the second part of the external light signal passes through the pixel definition layer 2942, it partially irradiates the light shielding block 280 to generate a third diffraction light signal, and partially irradiates the gap between the light shielding blocks without diffraction problems. The light signal that finally reaches the camera includes the first diffraction light signal, the second diffraction light signal, the third diffraction light signal, and the light signal without diffraction. It can be seen that the optical signal components reaching the camera through the first display area 240 are complex, resulting in poor imaging effect of the camera. In particular, the diffraction light signal is generated twice, first irradiated to the first pixel 246 and then irradiated to the light shielding block 280. It is no longer a periodic diffraction light signal, but a complex multiple diffraction light signal. It is difficult to remove the interference caused by this part of the complex diffraction light signal to the imaging through the image processing algorithm in the later stage.

[0045] Therefore, the light shielding block 280 and the first pixel 246 can be staggered to avoid generating multiple diffraction light signals. Specifically, the positive projection of the light shielding block 280 on the light emitting layer 294 does not overlap with the first pixel 246, which can also be understood as the positive projection of the light shielding block 280 on the light emitting layer 294 is located in the pixel definition layer and has no intersection with the first pixel 246. The following is still an example of an external light signal vertically irradiated to the first display area 240. The external light signal includes a first part of the external light signal and a second part of the external light signal. The first part of the external light signal irradiates the first pixel 246 to generate a first diffraction light signal. After passing through the first pixel 246, it is then irradiated to the gap between the light shielding blocks 280 without a diffraction light signal. The second part of the external light signal irradiates the pixel definition layer 2942 between the first pixels 246 without generating the first diffraction light signal. After passing through the pixel definition layer 2942, it is irradiated to the light shielding block 280 to generate a second diffraction light signal. Part of the external light signal irradiates the gap between the light shielding blocks without a diffraction light signal. The light signals that finally reach the camera include the first diffraction light signal, the second diffraction light signal, and the non-diffraction light signal. The components of the light signals reaching the camera are relatively simple, resulting in better imaging effects of the camera. The diffraction light signals are generated by the regularly arranged first pixels or light shielding blocks, and are all periodic diffraction light signals. It is easier to remove the periodic diffraction light signals through image processing algorithms later than the complex multiple diffraction light signals.

[0046] See also Figure 6 , Figure 6 A first structural schematic diagram of a first pixel and a first driving unit in a display device provided in an embodiment of the present application. The first display area 240 may include pixels of three colors, R, G, and B, and a first driving unit 248 drives a first pixel 246. The first driving unit 248 may include a first color driving unit 2482 for driving a first color pixel 2462, and a second color driving unit 2484 for driving a second color pixel 2464, and the relative position of the first color driving unit 2482 and the first color pixel 2462 is different from the relative position of the second color driving unit 2484 and the second color pixel 2464. Specifically, the first driving unit may include a first color driving unit 2482 for driving an R pixel 2462, and a second color driving unit 2484 for driving a G pixel 2464, and the projection of the first color driving unit 2482 for driving an R pixel 2462 on the pixel definition layer 294 is located on the right side of the R pixel 2462, and the projection of the second driving unit 2484 for driving the G pixel 2464 on the pixel definition layer 294 is located on the left side of the G pixel 2464. In this way, the RGB pixels are arranged regularly, but the first driving unit driving the R and G pixels does not correspond to the R and G pixels one by one, which destroys the regularity. At the same time, because the light shielding block 280 and the first pixel 246 are staggered, and the first driving unit 248 and the light shielding block 280 are arranged one by one, that is, the first driving unit 248 and the first pixel 246 are staggered, so as to avoid the appearance of multiple diffracted light signals in the process of external light passing through the first display area 240. It should be noted that the relative position of the B pixel 2466 and the third color driving unit 2486 driving the B pixel 2466 can be different from the relative position of the other two color pixels and their driving units, and the relative position of the B pixel 2466 and the third color driving unit 2486 driving the B pixel 2466 can also be the same as the relative position of one of the color pixels and its driving unit. It should be noted that the first pixel of this embodiment can include pixels of four colors: R, G, B, and W.

[0047] For a more comprehensive understanding of the display device of the present application, please refer to Figure 7 , Figure 7 Schematic diagram of a second stacked structure of the first display area in the display device provided in an embodiment of the present application. The first display area of ​​the display device includes a substrate 291, a driving circuit layer 292, an anode layer 293, a light-emitting layer 294, a common electrode layer 295, a planarization layer 296 and a touch layer 297 stacked in sequence.

[0048] The substrate 291 can be used as a supporting platform of the display device, and the substrate 291 can be made of glass, plastic, resin or other materials. For example, the material of the substrate 291 can be polyimide (PI).

[0049] The driving circuit layer 292 is disposed on the substrate 291. The driving circuit layer 292 includes a first driving unit 248 for driving the first pixel 246 in the first display area 240. Each first driving unit 248 includes at least one thin film transistor TFT. The source and drain of the thin film transistor are located in the same layer, and the gate is located between the source and the light emitting layer.

[0050] The anode layer 293 is disposed on the driving circuit layer 292. The anode layer 293 includes a first anode layer 2932, a first insulating layer 2934, and a second anode layer 2936. The first insulating layer 2934 is disposed between the first anode layer 2932 and the second anode layer 2936 to separate and insulate the first anode layer 2932 and the second anode layer 2936. The first anode layer 2932 includes a first signal line (gate line) in a first direction, and the second anode layer 2936 includes a second signal line (data line) in a second direction. The first direction and the second direction may be perpendicular. The first signal line and the second signal line are electrically connected to the first driving unit 248, respectively. The driving chip of the display device controls the first driving unit 248 through the first signal line and the second signal line. The first signal line and the second signal line may use ITO with high light transmittance to ensure the transmittance of the light-transmitting display area, and at the same time, reduce the diffraction caused by the first signal line and the second signal line. The first signal line can be located in the same layer as the gate in the second driving unit 268, and the second signal line can be electrically connected to the drain of the first driving unit 248 through the conductive portion located in the first via hole 2935. The anode layer 293 can also include a metal anode layer 2938, the metal anode layer 2938 is adjacent to the light-emitting layer 294, the metal anode layer 2938 and the first pixel 246 of the light-emitting layer 294 are directly adjacent and electrically connected, and there is a second insulating layer 2939 between the metal anode layer 2938 and the source in the first driving unit 248, and the metal anode layer 2938 can be electrically connected to the source of the first driving unit 248 through the conductive portion located in the pixel via hole. The metal anode layer 2938 can also be made of a highly transparent ITO material. It should be noted that in some other embodiments, the metal anode layer 2938 and the second anode layer 2936 can be located in the same layer, that is, the metal anode layer 2938 and the second anode layer 2936 are the same layer, and the first insulating layer and the second insulating layer can be the same layer.

[0051] The light emitting layer 294 is disposed on the anode layer 293 . The light emitting layer 294 includes a pixel definition layer 2942 . The pixel definition layer 2942 has a plurality of pixel holes. A first pixel 246 is disposed in each pixel hole. The first pixel 246 includes an organic light emitting material.

[0052] The common electrode layer 295 is disposed on the light emitting layer 294. The anode layer 293 and the common electrode layer 295 are disposed on both sides of the first pixel 246 and jointly drive the first pixel 246. The common electrode layer 295 can be made of ITO material with high light transmittance.

[0053] A planarization layer 296 may also be disposed on the common electrode layer 295. After the first pixel 246 is disposed on the pixel hole, the first pixel 246 does not fill the pixel hole. After the common electrode layer 295 is disposed on the first pixel 246, a groove may appear. The planarization layer 296 may fill the groove and cover the entire light-emitting layer 294 to protect the light-emitting layer 294, etc.

[0054] A touch layer 297 may be further disposed on the planarization layer 296 , and the touch layer 297 may be used to detect a user's touch operation.

[0055] A polarizer (not shown) may also be disposed on the touch layer 297 to prevent internal light from being transmitted out and prevent the user from seeing the internal drive unit and other components. The touch layer 297 and the polarizer may be laminated together and then disposed on the planarization layer 296.

[0056] The light shielding block 280 may be disposed in the first insulating layer 2934 and between the first driving unit 248 and the second insulating layer 2939. The light shielding block 280 may also be disposed in the second insulating layer 2939. It can be understood that the light shielding block 280 may be disposed adjacent to the driving circuit layer 292 or the light emitting layer 294, or may be disposed adjacent to the driving circuit layer 292 at one end and adjacent to the light emitting layer 294 at the other end, that is, the thickness of the light shielding block 280 may be the same as the thickness of the second insulating layer 2939.

[0057] It should be noted that in some other embodiments, some structures may be added or reduced as needed, which is not limited in the embodiments of the present application. For example, at least one of the touch layer 297 and the polarizer may be reduced. For another example, a protective layer may be added between the planarization layer 296 and the touch layer 297, and the protective layer may be made of the same material as the substrate 291.

[0058] Except for the first driving unit 248 in the driving circuit layer 292, each layer structure in the first display area 240 adopts light-transmitting materials to improve the light transmittance of the first display area 240. For example, the substrate 291, the pixel definition layer 2942, the common electrode layer 295, the planarization layer 296, and the touch layer 297 of the first display area 240 can be made of light-transmitting materials, and the signal line in the anode layer 293 can be made of light-transmitting materials such as ITO or nano silver. The TFT of the driving circuit layer 292 cannot be made of light-transmitting materials, and other parts of the driving circuit layer 292 except TFT can also be made of light-transmitting materials. It can be understood that the scheme of improving the light transmittance of the material and changing the arrangement of the wiring to improve the first display area 240 is within the scope of this application.

[0059] It should be noted that the second display area can adopt a stacked structure similar to that of the first display area. For details, please refer to the above embodiments, which will not be repeated here. At least one of the substrate, pixel definition layer, common electrode layer, planarization layer, touch layer, etc. of the second display area 220 can be made of the same light-transmitting material as the first display area 240. For example, the substrate can be made of light-transmitting materials such as glass or resin. At least one of the substrate, pixel definition layer, common electrode layer, planarization layer, touch layer, etc. of the second display area 220 can be made of different materials from the first display area 240. For example, the signal line in the anode layer of the second display area can be made of metal or alloy materials such as molybdenum, molybdenum aluminum molybdenum, Ag, etc. The second display area does not have a light shielding block, and the metal anode of the second display area can be made of metal materials, such as Mg, Ag, Al. The common electrode layer of the second display area can be made of materials such as Mg, Ag, etc. The common electrode layer of the second display area is connected to the common electrode layer of the first display area at the edge, and together constitute a complete common electrode layer. The light-emitting layer of the second display area 220 includes a plurality of second pixels, the material of the second pixels can be the same as that of the first pixels, and the transmittance is the same. The material of the first pixels can also be different from that of the second pixels, so that the transmittance of the first pixels is greater than that of the second pixels.

[0060] In order to improve the light transmittance of the first display area, the size of the first pixel in the first display area can be set to be larger than the size of the second pixel. Figure 8 , Figure 8 for Figure 2A second enlarged schematic diagram of the X portion in the middle. The size of the first pixel 246 in the first display area is larger than the size of the second pixel 226. In one embodiment, the spacing between the first pixels 246 is positively correlated with the size of the first pixel 246, that is, the larger the size of the first pixel 246, the larger the spacing between the first pixels 246. Therefore, the distribution density of the first pixels 246 in the first display area 240 is smaller than the distribution density of the second pixels 226 in the second display area 220, and the transmittance of the pixel definition layer between the first pixels 246 is greater than the transmittance of the first pixels 246. Therefore, the larger the size of the first pixel 246, the higher the transmittance of the first display area 240.

[0061] In order to improve the light transmittance of the first display area, the distribution density of the first pixels can also be set to be smaller than the distribution density of the second pixels. Fig. 9 , Fig. 9 for Figure 2 The third enlarged schematic diagram of the X portion in the middle. The size of the first pixel 246 of the first display area 240 is the same as the size of the second pixel 226. The spacing distance between the first pixels 246 is increased, so that the distribution density of the first pixels 246 is smaller than the distribution density of the second pixels 226, and the transmittance of the pixel definition layer between the first pixels 246 is greater than the transmittance of the first pixels 246. Therefore, the smaller the distribution density of the first pixels 246, the larger the spacing distance between the first pixels 246, and the higher the transmittance of the first display area 240. Exemplarily, the second pixel of the second display area can reach more than 400ppi, the size of the first pixel of the first display area can be four times that of the second pixel, and the first pixel of the first display area can be 200ppi.

[0062] In order to improve the transmittance of the first display area, the first driving unit arranged in the first display area can be a simple driving circuit. Specifically, the second display area includes a plurality of second driving units, and one second driving unit drives one second pixel. The first driving unit of the first display area can be a simpler driving circuit than the second driving unit of the second display area. The number of thin film transistors included in a first driving unit is less than the number of thin film transistors in a second driving unit. Because thin film transistors are opaque, the number of opaque thin film transistors in the first driving unit is small, the area they occupy is also small, the opaque area of ​​the driving circuit layer is also small, and the proportion of the transparent area of ​​the driving circuit layer is also high, which can improve the transmittance of the driving circuit layer and the first display area. For example, the second driving unit is a 7T1C driving circuit, and the first driving unit can be a 5T1C or 4T1C or 3T1C or 2T1C driving circuit.

[0063] In order to improve the light transmittance of the first display area, the distribution density of the first driving unit can also be set to be smaller than the distribution density of the second driving unit. Fig.10 and Fig.11 , Fig.10 for Figure 2 The fourth enlarged schematic diagram of the X part in the middle, Fig.11 A second structural schematic diagram of a first pixel and a first driving unit in a display device provided in an embodiment of the present application. A plurality of first pixels 246 in the first display area can be divided into a plurality of pixel sets 242, that is, the first display area includes a plurality of pixel sets 242, each pixel set 242 includes at least two first pixels 246 connected in parallel to each other, the physical structure of the first pixel 246 and the second pixel 226 are the same, and all first pixels 246 in the pixel set 242 share a first driving unit. The light-emitting layers of the first display area and the second display area can be formed in the same process, and there is no difference between the light-emitting layers of the first display area and the second display area. In the second display area, one second driving unit drives one second pixel. In the first display area, one first driving unit drives a plurality of first pixels 246 connected in parallel, which can reduce the number of first driving units and reduce the distribution density of the first driving units. The number of first driving units per unit area is less than the number of second driving units per unit area, and the transmittance of the first display area can be improved relative to the second display area. Among them, the number of thin film transistors included in the first driving unit is less than the number of thin film transistors of the second driving unit, further improving the transmittance of the first display area.

[0064] The same physical structure of the first pixel and the second pixel can be understood as the same size, distribution density, arrangement mode, etc. The arrangement mode can be one of the standard RGB arrangement, Pentile arrangement, or Delta arrangement.

[0065] The first pixel parallel connection may be realized by connecting the first pixels in the light emitting layer in parallel, or by connecting the metal anodes in the anode layer in parallel.

[0066] See also Fig.12 , Fig.12A schematic diagram of a polarizer in a display device provided in an embodiment of the present application. The display device also includes a polarizer 298, and the polarizer 298 includes a first polarizer 2982 corresponding to the first display area, and a second polarizer 2984 corresponding to the second display area. The transmittance of the first polarizer 2982 is greater than the transmittance of the second polarizer 2984, and the polarization of the first polarizer 2982 is less than the polarization of the second polarizer 2984. The first polarizer 2982 can be a through hole or a light-transmitting material. For example, a through hole is first set corresponding to the first display area, and then a transparent material is filled in the through hole to form the first polarizer 2982. For another example, a through hole is first set corresponding to the first display area, and then a high-transmittance and low-polarization material is filled in the through hole to form the first polarizer 2982, so that the first polarizer 2982 can achieve both the function of high transmittance and the function of preventing light from being reflected out, allowing the user to see the internal structure. For example, the proportion of iodine molecules in the first polarizing region 2982 may be smaller than that in the second polarizing region 2984 , thereby achieving that the polarization of the first polarizing region 2982 is smaller than that of the second polarizing region 2984 .

[0067] The stacked structure of the first display area can also be other structures, which are not limited in the embodiments of the present application. Fig.13 , Fig.13 A schematic diagram of a third stacked structure of the first display area in the display device provided in an embodiment of the present application. The stacked structure of the first display area in this embodiment is mainly different from that in the above embodiment in the driving circuit layer and the anode layer. The source and drain of the thin film transistor of the first driving unit of the first display area are located in the same layer, and the source is located between the gate and the light-emitting layer.

[0068] The anode layer 293 is partially disposed on the driving circuit layer 292. The anode layer 293 includes a first anode layer 2932, a first insulating layer 2934, and a second anode layer 2936. The first insulating layer 2934 is disposed between the first anode layer 2932 and the second anode layer 2936 to separate and insulate the first anode layer 2932 and the second anode layer 2936. The first anode layer 2932 includes a first signal line (gate line) in a first direction, and the second anode layer 2936 includes a second signal line (data line) in a second direction. The first direction and the second direction can be vertically disposed. The first signal line and the second signal line are electrically connected to the first driving unit 248, respectively. The driving chip of the display device controls the first driving unit 248 through the first signal line and the second signal line. The first signal line can be located at the same layer as the gate in the first driving unit 248, and the second signal line can be located at the same layer as the drain in the first driving unit 248. The anode layer 293 may further include a metal anode layer 2938, the metal anode layer 2938 is adjacent to the light emitting layer 294, the metal anode of the metal anode layer 2938 and the first pixel 246 of the light emitting layer 294 are directly adjacent to and electrically connected, a second insulating layer 2939 is provided between the metal anode layer 2938 and the source in the first driving unit 248, and the metal anode may be electrically connected to the source of the first driving unit 248 through the pixel via 2937. The light shielding block 280 is disposed on the second insulating layer 2939 between the metal anode layer 2938 and the second anode layer 2936.

[0069] The present application also provides an electronic device, which includes a display device and a camera. Fig.14 Combined with Figure 1 , Fig.14 A schematic diagram of the structure of the first pixel and the first driving unit of the display device of the electronic device provided in the embodiment of the present application. The display device 20 includes a driving circuit layer 292 and a light-emitting layer 294 arranged in a stacked manner, and the display device is formed with a first display area 240; the driving circuit layer 292 located in the first display area 240 includes a plurality of first driving units 248; the light-emitting layer 294 located in the first display area 240 includes a plurality of first pixels 246; each first driving unit 248 is used to drive at least one first pixel 246, and the projection of the first pixel 246 on the driving circuit layer 292 does not overlap with the first driving unit 248. The camera 60 is arranged on one side of the display device 20 and is arranged toward the first display area 240, and the camera 60 is used to obtain external light signals passing through the first display area 240 for imaging.

[0070] The projection of the first pixel 246 on the driving circuit layer 292 does not overlap with the first driving unit 248, and the optical signal components that pass through the first display area 240 and reach the camera 60 are relatively simple, and the imaging effect is good. The optical signal with diffraction problems is generated by the regularly arranged first pixels 246, etc., which are all periodic diffraction problems. The post-processing of the relatively complex multiple diffraction problems is easier to handle. For details, please refer to the above embodiment, which will not be repeated here.

[0071] The display device 20 also forms a second display area 220, and the light transmittance of the first display area 240 is greater than the light transmittance of the second display area 220. Fig.15 , Fig.15 A schematic diagram of the structure of the second pixel and the second driving unit of the display device of the electronic device provided in the embodiment of the present application. The driving circuit layer 292 also includes a plurality of second driving units 228; the light-emitting layer 294 located in the second display area 220 includes a plurality of second pixels 226; each second driving unit 228 is used to drive a second pixel 226, and the projection of the second pixel 226 on the driving circuit layer 292 at least partially overlaps with the second driving unit 228. The camera does not need to obtain the light signal passing through the second display area, the second driving unit and the second pixel of the second display area are arranged relative to each other, and the distance between the second driving unit and the second pixel is short, which is convenient for controlling the second pixel.

[0072] The number of thin film transistors included in a first driving unit 248 is less than the number of thin film transistors included in a second driving unit 228. Because thin film transistors are opaque, the number of opaque thin film transistors in the first driving unit 248 is small, and the area they occupy is also small. The opaque area of ​​the driving circuit layer 292 located in the first display area 240 is also small, and the proportion of the transparent area of ​​the driving circuit layer 292 located in the first display area 240 is also high, which can improve the transmittance of the first display area 240. For example, the second driving unit 228 is a 7T1C driving circuit, and the first driving unit 248 can be a 5T1C or 4T1C or 3T1C or 2T1C driving circuit.

[0073] The display device further includes an anode, wherein the anode layer is disposed between the driving circuit layer and the light emitting layer. The anode layer includes a first anode layer, a first insulating layer and a second anode layer stacked together, wherein the first insulating layer is used to separate and insulate the first anode layer from the second anode layer.

[0074] The anode layer located in the first display area is made of transparent conductive material (such as ITO), and the anode layer located in the second display area is made of metal material (such as molybdenum, molybdenum aluminum molybdenum, silver and other metals or alloy materials). The transmittance of the light-transmitting conductive material is greater than that of the metal material, so that the transmittance of the first display area can be greater than the transmittance of the second display area.

[0075] The following description will be made by taking the anode layer of the first display area as an example. Figure 7 The anode layer 293 includes a first anode layer 2932, a first insulating layer 2934 and a second anode layer 2936. The first insulating layer 2934 is disposed between the first anode layer 2932 and the second anode layer 2936 to separate and insulate the first anode layer 2932 and the second anode layer 2936. The first anode layer 2932 includes a first signal line (gate line) in a first direction, and the second anode layer 2936 includes a second signal line (data line) in a second direction. The first direction and the second direction may be perpendicular. The first signal line and the second signal line are electrically connected to the first driving unit 248, respectively. The driving chip of the display device controls the first driving unit 248 through the first signal line and the second signal line. The first signal line and the second signal line may be made of ITO with high light transmittance to ensure the transmittance of the light-transmitting display area, and at the same time, the diffraction caused by the first signal line and the second signal line may be reduced. The first signal line may be located in the same layer as the gate in the second driving unit 268, and the second signal line may be electrically connected to the drain of the first driving unit 248 through the conductive portion located in the first via 2935. The anode layer 293 may also include a metal anode layer, the metal anode layer is adjacent to the light emitting layer 294, the metal anode 2938 of the metal anode layer and the first pixel 246 of the light emitting layer 294 are directly adjacent to and electrically connected, and a second insulating layer 2939 is provided between the metal anode layer and the source electrode in the first driving unit 248, and the metal anode 2938 may be electrically connected to the source electrode of the first driving unit 248 through a conductive portion located in the pixel via hole. The metal anode 2938 may also be made of highly transparent ITO. It should be noted that, in some other embodiments, the metal anode in the metal anode layer may be located in the same layer as the second signal line in the second anode layer, that is, the metal anode layer and the second anode layer are the same layer, and the first insulating layer and the second insulating layer may be the same layer; the metal anode in the metal anode layer may also be located in a different layer from the second anode layer, and the metal anode layer and the second anode layer are separated and insulated by the second insulating layer.

[0076] The first insulating layer 2934 located in the first display area 240 is provided with a plurality of light shielding blocks 280 . Each light shielding block 280 is at least partially disposed opposite to a first driving unit 248 . The light shielding block 280 is used to shield the external light signal irradiating the first driving unit 248 .

[0077] During the imaging process of the camera acquiring the external light signal through the first display area, because the first driving unit 248 of the driving circuit layer 292 of the first display area includes an opaque part such as a thin film transistor, the external light signal will produce stray light reflected and refracted after being irradiated to the first driving unit 248, thereby affecting the imaging effect of the camera. In the embodiment of the present application, a light shielding block 280 is arranged between the first driving unit 292 and the light-emitting layer 294. The light shielding block 280 is at least partially arranged opposite to the first driving unit 248. It can also be understood that the positive projection of the light shielding block 280 on the driving circuit layer 292 overlaps with the first driving unit 248 at least partially. The light shielding block 280 can be used to block the external light signal irradiated to the first driving unit 248, reducing the stray light interference problem caused by the reflection and refraction of the first driving unit 248. When the camera acquires the external light signal through the first display area for imaging, the light shielding block 280 can reduce the stray light interference and improve the imaging quality of the camera. Among them, the light shielding block 280 can be a black light-absorbing material. The shape, size, and arrangement of the light shielding block 280 may be set according to the first driving unit 248. The orthographic projection of the light shielding block 280 on the driving circuit layer 292 may partially or completely cover the first driving unit 248.

[0078] In addition to being arranged on the first insulating layer, the light shielding block can also be arranged on the second insulating layer, such as Fig.13 The second insulating layer 2939 is located between the driving circuit layer 292 and the light-emitting layer 394. The second insulating layer 2939 located in the first display area is provided with a plurality of light shielding blocks 280. Each light shielding block 280 is at least partially arranged opposite to a first driving unit 248. The light shielding block 280 is used to shield the external light signal irradiating the first driving unit 248.

[0079] The display device also includes a common electrode layer 295, which is arranged on the side of the light-emitting layer 294 away from the driving circuit layer 292. The common electrode layer located in the first display area is made of transparent conductive material, and the common electrode layer located in the second display area is made of metal material (such as ITO). The transmittance of the light-transmitting conductive material is greater than that of the metal material (such as metal magnesium, silver, etc.), so that the transmittance of the first display area can be greater than the transmittance of the second display area.

[0080] Please continue reading Fig.12 The display device further includes a polarizer 298, the polarizer 298 includes a first polarizer region 2982 corresponding to the first display region, and a second polarizer region 2984 corresponding to the second display region, the transmittance of the first polarizer region 2982 is greater than the transmittance of the second polarizer region 2984, and the polarization of the first polarizer region 2982 is less than the polarization of the second polarizer region 2984. The specific structure of the polarizer can adopt the structure of the polarizer in the above embodiment, which will not be repeated here.

[0081] The specific structure of the first display area may adopt the structure of the first display area in the above embodiment, and / or the specific structure of the second display area may adopt the structure of the second display area in the above embodiment, which will not be described in detail here.

[0082] It should be noted that the display device in the electronic device may also be the display device in any of the above embodiments.

[0083] The lens of the camera in the electronic device faces the 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 substrate of the display device. The 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 substrate. For details, please refer to Fig.16 , Fig.16 A schematic diagram of the first structure of the display device and camera of the electronic device provided in the embodiment of the present application. A first mounting hole 2912 is set at the position of the 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 substrate 291 relative to the camera 60 is less than the thickness of the other parts. The substrate 291 is still a complete substrate, 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.

[0084] It should be noted that the camera 60 relative to the first display area 240 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 driving circuit layer 292 of the display device can be provided with a first mounting hole 2912, then the camera 60 relative to the first display area 240 can be a camera 60 with a movable lens 62, and the movable lens 62 of the camera 60 is used to realize functions such as autofocus.

[0085] 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.

[0086] 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.

[0087] 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.
