[0044] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0045] The present application provides a display device, and the display device 100 may be a liquid crystal display device or an organic light emitting diode display device. Specifically, the display device 100 is an organic light emitting diode display device.
[0046] See also Figure 1 and Figure 2 As shown, Figure 1 is a plan view of a display device according to an embodiment of the present application, Figure 2 for Figure 1 Schematic diagram of the distribution of first display pixels and second display pixels in the display device shown. The display device 100 has a display light-transmitting area 100a, a main display area 100c and a transition display area 100b. The display device 100 includes a plurality of first display pixels, a plurality of first pixel driving circuits (not shown), a plurality of second display pixels, a plurality of pixel driving circuit islands, a plurality of first signal lines 102 and a plurality of second signal lines 103.
[0047] The transitional display area 100b is arranged between the display light-transmitting area 100a and the main display area 100c. Both the main display area 100c and the transitional display area 100b are used for display. While the display light-transmitting area 100a is used for display, it also has a high light transmittance property. The light transmittance of the display light-transmitting area 100a is greater than the light transmittance of the main display area 100c and the transitional display area 100b. The area of the main display area 100c is greater than the area of the transitional display area 100b and the area of the display light-transmitting area 100a.
[0048] The display light-transmitting area 100a has an arc-shaped boundary, and the shape of the display light-transmitting area 100a is an ellipse, a circle, a chamfered square or other shapes. The transition display area 100b is an annular shape. The transition display area 100b is any one of an ellipse ring, a circular ring or a square ring.
[0049] Specifically, the display light-transmitting area 100a is circular. The display light-transmitting area 100a is symmetrically arranged about the first symmetry axis AA and the second symmetry axis BB, and the first symmetry axis AA is perpendicular to the second symmetry axis BB. The transition display area 100b is annular, and the boundary of the transition display area 100b near the display light-transmitting area 100a is circular.
[0050] A plurality of first display pixels are uniformly arranged in the main display area 100c, and each first display pixel includes a first red sub-pixel 100c1, a first green sub-pixel 100c3, and a first blue sub-pixel 100c2. The first red sub-pixel 100c1, the first green sub-pixel 100c3, and the first blue sub-pixel 100c2 are distributed in the main display area 100c in a Pentile design. The first green sub-pixel 100c3 is elliptical in shape, and the first red sub-pixel 100c1 and the first blue sub-pixel 100c2 are octagonal in shape.
[0051] A plurality of first pixel driving circuits are also arranged in the main display area 100c. One first pixel driving circuit corresponds to driving one sub-pixel (one of the first red sub-pixel 100c1, the first green sub-pixel 100c3 and the first blue sub-pixel 100c2) of the main display area 100c to emit light. The first pixel driving circuit can adopt any one of the common 7T1C, 6T1C, 5T1C, 4T1C, 3T1C and 2T1C. Each first pixel driving circuit includes a plurality of metal film layers, and the plurality of first pixel driving circuits are arranged in an array in the main display area 100c, resulting in low light transmittance of the main display area 100c.
[0052] A plurality of second display pixels are uniformly arranged in the display light transmission area 100a and the transition display area 100b. Each second display pixel includes a second red sub-pixel 100a1, a second green sub-pixel 100a3 and a second blue sub-pixel 100a2. The second red sub-pixel 100a1, the second green sub-pixel 100a3 and the second blue sub-pixel 100a2 are all distributed in a Pentile design in the display light transmission area 100a and the transition display area 100b. The second red sub-pixel 100a1, the second green sub-pixel 100a3 and the second blue sub-pixel 100a2 are all circular in shape.
[0053] The size of the first red sub-pixel 100c1 is larger than that of the second red sub-pixel 100a1, the size of the first green sub-pixel 100c3 is larger than that of the second green sub-pixel 100a3, and the size of the first blue sub-pixel 100c2 is larger than that of the second blue sub-pixel 100a2, so as to ensure that the display light-transmitting area 100a has high transmittance. Since the size of a second red sub-pixel 100a1 is different from that of a first red sub-pixel 100c1, the driving powers of the driving circuits corresponding to the two are also different. Similarly, the driving powers of the first green sub-pixel 100c3 and the second green sub-pixel 100a3 are also different, and the driving powers of the first blue sub-pixel 100c2 and the second blue sub-pixel 100a2 are also different. Therefore, the first pixel driving circuit can only be used to drive the first red sub-pixel 100c1, the first green sub-pixel 100c3 and the first blue sub-pixel 100c2 in the main display area 100c, but cannot be used to drive the second red sub-pixel 100a1, the second green sub-pixel 100a3 and the second blue sub-pixel 100a2 in the transition display area 100b and the display light-transmitting area 100a. From the main display area 100c to the transition display area 100b, the size of the sub-pixel becomes smaller.
[0054] like Figure 3-Figure 5 As shown, Figure 3 for Figure 1 A first partial schematic diagram of the display device shown, Figure 4 for Figure 1 A partial enlarged schematic diagram of the display device shown, Figure 5 for Figure 3 Schematic diagram of a pixel driving circuit island in FIG. A plurality of pixel driving circuit islands 101 are arranged in the transition display area 100b, and each pixel driving circuit island 101 includes a plurality of second pixel driving circuits 1011. The second pixel driving circuits 1011 of the plurality of pixel driving circuit islands 101 are used to drive a plurality of second display pixels to emit light, that is, the second pixel driving circuits 1011 of the plurality of pixel driving circuit islands 101 are used to drive the second display pixels of the transition display area 100b to emit light, and are also used to drive the second display pixels of the display light-transmitting area 100a to emit light, so as to avoid setting a pixel driving circuit in the display light-transmitting area 100a, and avoid the metal film layer of the second pixel driving circuit 1011 affecting the transmittance of the display light-transmitting area 100a, thereby further improving the transmittance of the display light-transmitting area 100a.
[0055] The second pixel driving circuit 1011 in the pixel driving circuit island 101 is electrically connected to the second display pixel of the display light-transmitting area 100a through a transparent wire to further improve the light transmittance of the display light-transmitting area 100a. The transparent wire is made of at least one material selected from indium tin oxide or indium zinc oxide. The second pixel driving circuit 1011 in the pixel driving circuit island 101 can be electrically connected to the second display pixel of the transition display area 100b through a metal wire.
[0056] It should be noted that the pixel driving circuit island 101 refers to a plurality of second pixel driving circuits 1011 arranged together. The distance between two adjacent pixel driving circuit islands 101 is greater than the distance between two adjacent second pixel driving circuits 1011.
[0057] Different from the main display area 100c, a second pixel driving circuit 1011 can be used to drive at least two of the plurality of second red sub-pixels 100a1, the plurality of second green sub-pixels 100a3, and the plurality of second blue sub-pixels 100a2, so as to reduce the number of second pixel driving circuits 1011 and reduce the space occupied by the pixel driving circuit island 101, so that the size of the display light-transmitting area 100a can be increased or the transition display area 100b has more space. The second pixel driving circuit 1011 can be used to drive the sub-pixels emitting the same color light and / or the sub-pixels emitting different color light in the plurality of second red sub-pixels 100a1, the plurality of second green sub-pixels 100a3, and the plurality of second blue sub-pixels 100a2. In the display light-transmitting area 100a, the sub-pixels driven by the same second pixel driving circuit 1011 are electrically connected through transparent wires.
[0058] Specifically, two second red sub-pixels 100a1 are driven by the same second pixel driving circuit 1011 , two second blue sub-pixels 100a2 are driven by the same second pixel driving circuit 1011 , and four second green sub-pixels are driven by the same second pixel driving circuit 1011 .
[0059] A plurality of first signal lines 102 extend from the main display area 100c to the transition display area 100b, and a plurality of second signal lines 103 extend from the main display area 100c to the transition display area 100b, and the plurality of first signal lines 102 and the plurality of second signal lines 103 are not arranged in the display light-transmitting area 100a. The preparation materials of the plurality of first signal lines 102 and the plurality of second signal lines 103 are all metals, and the metals include but are not limited to molybdenum, aluminum, titanium and copper. The plurality of first signal lines 102 and the plurality of second signal lines 103 are not arranged in the display light-transmitting area 100a, so as to further improve the light transmittance of the display light-transmitting area 100a.
[0060] Specifically, the first signal line 102 is a data line, and the data line is used to transmit a data signal. The second signal line 103 is selected from at least one of a scan line, a reset line, and a light-emitting control signal line, wherein the scan line is used to transmit a scan signal, the reset line is used to transmit a reset signal and / or an initialization signal, and the light-emitting control signal line is used to transmit a light-emitting control signal.
[0061] In the main display area 100c, the plurality of first signal lines 102 intersect the plurality of second signal lines 103 perpendicularly, the plurality of first signal lines 102 are parallel to each other and the spacing between any two adjacent first signal lines 102 is equal, and the plurality of second signal lines 103 are parallel to each other and the spacing between any two adjacent second signal lines 103 is equal, and the plurality of second signal lines 103 intersect the plurality of first signal lines 102 perpendicularly.
[0062] In the transition display area 100b, since the multiple second pixel driving circuits 1011 form multiple pixel driving circuit islands 101, each pixel driving circuit island 101 is electrically connected to at least two of the multiple first signal lines 102, and is electrically connected to at least two of the multiple second signal lines 103, so that the multiple first signal lines 102 need to be adjusted and divided into multiple groups of first signal lines 102 when extending to the transition display area 100b, each group of first signal lines 102 is connected to a pixel driving circuit island 101, and the multiple second signal lines 103 need to be changed and divided into multiple groups when extending to the transition display area 100b, and each group of second signal lines 103 is connected in series with multiple pixel driving circuit islands 101.
[0063] like Figure 3 as well as Figure 4As shown, each first signal line 102 includes a first connecting segment 1021, and the first connecting segments 1021 of multiple first signal lines 102 are connected to multiple pixel driving circuit islands 101 so that data signals are transmitted to the second pixel driving circuits 1011 of the multiple pixel driving circuit islands 101, and the first connecting segments 1021 of the multiple first signal lines 102 are arranged between the multiple pixel driving circuit islands 101 and the display light-transmitting area 100a.
[0064] Compared with the Chinese patent with publication number CN110491917A, in which the second detour sections of multiple second signal lines are arranged at the periphery of the pixel driving circuit island, the second detour sections of multiple second signal lines need to be connected to the corresponding pixel driving circuit island by changing lines, which will increase the complexity of wiring, and the longer length of the second detour sections of multiple second signal lines will result in a larger impedance difference between the second signal line with the second detour section and the second signal line of the main display area, resulting in uneven display in the main display area. In the present application, the first connection segments 1021 of the plurality of first signal lines 102 are arranged between the plurality of pixel driving circuit islands 101 and the display light-transmitting area 100a, so that the first connection segments 1021 of the plurality of first signal lines 102 can be directly connected to the corresponding pixel driving circuit islands 101 without changing the line, so that the wiring complexity of the first connection segments 1021 of the plurality of first signal lines 102 is reduced, and the first connection segments 1021 of the plurality of first signal lines 102 are arranged between the plurality of pixel driving circuit islands 101 and the display light-transmitting area 100a, so that the length of the first connection segments 1021 of the plurality of first signal lines 102 is reduced, thereby improving the problem that the length of the first connection segments 1021 of the plurality of first signal lines 102 is too long, resulting in a large impedance difference between the first signal line 102 with the first connection segment 1021 and the first signal line of the main display area 100c, thereby improving the display unevenness problem between the pixels connected to the first signal line 102 with the first connection segment 1021 and the pixels connected to the straight first signal line in the main display area 100c.
[0065] Please combine Figure 3 and Figure 6 , Figure 6It is a partial enlarged schematic diagram of the junction of the main display area and the transition display area. Each first signal line 102 also includes a first transition section 1022. The first transition sections 1022 of multiple first signal lines 102 are arranged between multiple pixel driving circuit islands 101 and the main display area 100c, and are connected to multiple pixel driving circuit islands 101. On the one hand, the first transition sections 1022 of some first signal lines 102 are adjusted relative to the first signal lines 102 in the main display area 100c to adapt to the differences when the first signal lines 102 are respectively connected to the first pixel driving circuit of the main display area 100c and the pixel driving circuit island 101 of the transition display area 100b. The layout of the first transition section 1022 needs to occupy the space between multiple pixel driving circuit islands 101 and the main display area 100c for adjustment and then connected to multiple pixel driving circuit islands 101. On the other hand, the plurality of pixel driving circuit islands 101 are arranged closer to the center of the display light-transmitting area 100c, ensuring that the second pixel driving circuit 1011 in the pixel driving circuit island 101 corresponding to the second display pixel at the center of the display light-transmitting area 100a can drive the second display pixel at the center.
[0066] At least part of the first transition section 1022 includes a fan-shaped section 10221 and a straight section 10222 connected to the fan-shaped section 10221. The fan-shaped sections 10221 of multiple first transition sections 1022 are gathered and distributed in a fan shape, narrowed into a group of first signal lines 102, and connected to the pixel driving circuit island 101 through the straight sections 10222 of multiple first transition sections 1022.
[0067] A plurality of pixel driving circuit islands 101 are distributed around the display light-transmitting area 100a, so that the plurality of pixel driving circuit islands 101 adapt to the shape setting of the display light-transmitting area 100a, and reduce the spacing between the second pixel driving circuit 1011 and the corresponding sub-pixel in the plurality of pixel driving circuit islands 101, thereby reducing the impedance of the wire connecting the second pixel driving circuit 1011 and the corresponding sub-pixel, and improving the uniformity of the light emission of the second display pixel.
[0068] like Figure 4As shown, the plurality of pixel driving circuit islands 101 include a first group of pixel driving circuit islands 101a and a second group of pixel driving circuit islands 101b, the pixel driving circuit islands 101 in the first group of pixel driving circuit islands 101a are distributed in an arc shape, the pixel driving circuit islands 101 in the second group of pixel driving circuit islands 101b are distributed in an arc shape, and the pixel driving circuit islands 101 in the first group of pixel driving circuit islands 101a and the pixel driving circuit islands 101 in the second group of pixel driving circuit islands 101b are symmetrically arranged about the second symmetry axis BB. The pixel driving circuit islands 101 in the first group of pixel driving circuit islands 101a are symmetrically arranged about the first symmetry axis AA. The pixel driving circuit islands 101 in the second group of pixel driving circuit islands 101b are symmetrically arranged about the first symmetry axis AA. The connecting section of each first signal line 102 is connected between the pixel driving circuit island 101 in the first group of pixel driving circuit islands 101a and the corresponding pixel driving circuit island 101 in the second group of pixel driving circuit islands 101b, so that the data signal is transmitted between the pixel driving circuit island 101 in the first group of pixel driving circuit islands 101a and the corresponding pixel driving circuit island 101 in the second group of pixel driving circuit islands 101b.
[0069] From the direction close to the first symmetry axis AA to the direction away from the first symmetry axis AA, the number of second pixel driving circuits 1011 in at least some of the pixel driving circuit islands 101 in the first group of pixel driving circuit islands 101a decreases; from the direction close to the first symmetry axis AA to the direction away from the first symmetry axis AA, the number of second pixel driving circuits 1011 in at least some of the pixel driving circuit islands 101 in the second group of pixel driving circuit islands 101b decreases, so that the pixel driving circuit islands 101 including more second pixel driving circuits 1011 can correspondingly drive more sub-pixels of the second display pixel, and the pixel driving circuit islands 101 including fewer second pixel driving circuits 1011 can correspondingly drive more sub-pixels of the second display pixel. The driving circuit island 101 can correspondingly drive fewer sub-pixels of the second display pixel, adapting to the situation that the number of sub-pixels of the second display pixel in the display light-transmitting area 100a from close to the first symmetry axis AA to far away from the first symmetry axis AA decreases, and when part of the second pixel driving circuits 1011 of the pixel driving circuit island 101 drive the second display pixel corresponding to the pixel driving circuit island 101 in the display light-transmitting area 100a (the second display pixel directly below or directly above the pixel driving circuit island 101), the number of sub-pixels in the display light-transmitting area 100c driven by part of the pixel driving circuit island 101 decreases from close to the first symmetry axis AA to far away from the first symmetry axis AA. The pixel driving circuit island 101 in the first group of pixel driving circuit islands 101a and the corresponding pixel driving circuit island 101 in the second group of pixel driving circuit islands 101b are used to drive the second display pixels at the positions of the two, between the two, and near the two.
[0070] Specifically, the plurality of pixel driving circuit islands 101 are in strip shape, and the widths of the plurality of pixel driving circuit islands 101 are the same. From the direction close to the first symmetry axis AA to the direction away from the first symmetry axis AA, the heights of at least some of the pixel driving circuit islands 101 in the first group of pixel driving circuit islands 101a decrease gradually; from the direction close to the first symmetry axis AA to the direction away from the first symmetry axis AA, the heights of at least some of the pixel driving circuit islands 101 in the second group of pixel driving circuit islands 101b decrease gradually. The width of each pixel driving circuit island 101 may be 60 micrometers to 100 micrometers, for example, 70 micrometers.
[0071] The heights of some adjacent pixel driving circuit islands 101 close to the first symmetry axis AA in the first group of pixel driving circuit islands 101a are the same, and the heights of some adjacent pixel driving circuit islands 101 close to the first symmetry axis AA in the second group of pixel driving circuit islands 101b are the same, so as to adapt to the situation that the number of second display pixels at corresponding positions in the transition display area 100b and the display light-transmitting area 100a close to the first symmetry axis AA is the same and the number of sub-pixels of the second display pixels driven by the pixel driving circuit islands 101 is the same.
[0072] The spacing between any two adjacent pixel driving circuit islands 101 in at least some of the pixel driving circuit islands 101 in the first group of pixel driving circuit islands 101a is equal; the spacing between any two adjacent pixel driving circuit islands 101 in at least some of the pixel driving circuit islands 101 in the second group of pixel driving circuit islands 101b is equal.
[0073] Specifically, the spacing between two adjacent pixel driving circuit islands 101 close to the first symmetry axis AA in the first group of pixel driving circuit islands 101a and the second group of pixel driving circuit islands 101b is 50 micrometers to 70 micrometers, for example, 60 micrometers.
[0074] In the direction from close to the first symmetry axis AA to away from the first symmetry axis AA, the spacing between at least part of the pixel driving circuit islands 101 in the first group of pixel driving circuit islands 101a and the corresponding pixel driving circuit islands 101 in the second group of pixel driving circuit islands 101b decreases, so that when multiple pixel driving circuit islands 101 are arranged around the display light-transmitting area 100a, they adapt to the circular design of the display light-transmitting area 100a, and at the same time, it is beneficial to shorten the length of the first signal line 102 connecting the pixel driving circuit island 101 in the first group of pixel driving circuit islands 101a and the corresponding pixel driving circuit islands 101 in the second group of pixel driving circuit islands 101b, so as to avoid the connection section 1021 of the first signal line 102 being too long, resulting in a large impedance and thus affecting the display effect.
[0075] The first group of pixel driving circuit islands 101a includes a first pixel driving circuit island 101a1 and a second pixel driving circuit island 101a2 that are adjacent to and close to the first symmetry axis AA, and the second group of pixel driving circuit islands 101b includes a third pixel driving circuit island 101b1 that is corresponding to the first pixel driving circuit island 101a1 and a fourth pixel driving circuit island 101b2 that is corresponding to the second pixel driving circuit island 101a2, and the spacing between the first pixel driving circuit island 101a1 and the third pixel driving circuit island 101b1 is equal to the spacing between the second pixel driving circuit island 101a2 and the fourth pixel driving circuit island 101b2. The number of second pixel driving circuits 1011 included in the first pixel driving circuit island 101a1 is the same as the number of second pixel driving circuits 1011 included in the third pixel driving circuit island 101b1. The number of second pixel driving circuits 1011 included in the second pixel driving circuit island 101a2 is the same as the number of second pixel driving circuits 1011 included in the fourth pixel driving circuit island 101b2.
[0076] The first connection segments 1021 of the plurality of first signal lines 102 include a first group of circuitous connection segments 102a and a second group of circuitous connection segments 102b, the first group of circuitous connection segments 102a and the second group of circuitous connection segments 102b are located on opposite sides of the display light-transmitting area 100a and are symmetrically arranged about the first symmetry axis AA, and the first group of circuitous connection segments 102a and the second group of circuitous connection segments 102b are both arranged around the display light-transmitting area 100a, the first group of circuitous connection segments 102a and the second group of circuitous connection segments 102b are both arranged between the display light-transmitting area 100a and the plurality of pixel driving circuit islands 101, the first connection segments 1021 in the first group of circuitous connection segments 102a are symmetrically arranged about the second symmetry axis BB, and the first connection segments 1021 in the second group of circuitous connection segments 102b are symmetrically arranged about the second symmetry axis BB. The first connection segment 1021 in the first group of roundabout connection segments 102a and the first connection segment 1021 in the second group of roundabout connection segments 102b are both arcs, so that the first signal line 102 avoids the display light-transmitting area 100a. At the same time, the shapes of the first connection segment 1021 in the first group of roundabout connection segments 102a and the first connection segment 1021 in the second group of roundabout connection segments 102b are adapted to the shape of the display light-transmitting area 100a to minimize the length of the first connection segment 1021, reduce the difference in length between the first signal line 102 having the first connection segment 1021 in the first group of roundabout connection segments 102a and the second group of roundabout connection segments 102b and the length of the first signal line 102 in the main display area 100c, and thereby maximize the improvement of the problem of uneven display in the main display area 100c due to impedance difference.
[0077] In the direction from close to the second symmetry axis BB to far away from the second symmetry axis BB, the number of first connection segments 1021 in the first group of circuitous connection segments 102a decreases, and the number of first connection segments 1021 in the second group of circuitous connection segments 102b decreases, so that the pixel driving circuit islands 101 close to the first symmetry axis AA in the first group of pixel driving circuit islands 101a are connected to the corresponding pixel driving circuit islands 101 in the second group of pixel driving circuit islands 101b through the arc-shaped first connection segments 1021 with a longer length, and the pixel driving circuit islands 101a in the first group of pixel driving circuit islands 101a far away from the first symmetry axis AA are connected to the corresponding pixel driving circuit islands 101 in the second group of pixel driving circuit islands 101b through the arc-shaped first connection segments 1021 with a longer length. The pixel driving circuit island 101 of axis AA is connected to the corresponding pixel driving circuit island 101 in the second group of pixel driving circuit islands 101b through an arc-shaped first connecting segment 1021 with a shorter length, so that while multiple first connecting segments 1021 are connected in series with the pixel driving circuit island 101 in the first group of pixel driving circuit islands 101a and the corresponding pixel driving circuit islands 101 in the second group of pixel driving circuits 101b, the lengths of the multiple first connecting segments 1021 are minimized, thereby improving the display difference of the main display area 100c and avoiding short circuits between the multiple first connecting segments 1021.
[0078] The first connection segments 1021 of the plurality of first signal lines 102 further include straight connection segments 10211, a portion of which is connected between the pixel driving circuit island 101 in the first group of pixel driving circuit islands 101a and the corresponding pixel driving circuit island 101 in the second group of pixel driving circuit islands 101b, and is located on the side of the first group of circuitous connection segments 102a and the second group of circuitous connection segments 102b away from the display light-transmitting area 100a. Compared with the background art in which the second circuitous segments of the plurality of second signal lines are all designed as windings, some of the connection segments in the present application are straight connection segments, which further reduces the display unevenness problem caused by the impedance difference of the first signal lines.
[0079] Another part of the straight connecting segment 10211 is connected between the first connecting segment 1021 in the first group of circuitous connecting segments 102a and the second group of circuitous connecting segments 102b and the multiple pixel driving circuit islands 101, so as to further shorten the length of the first connecting segment 1021 of the multiple first signal lines 102, further reduce the impedance difference of the first signal lines, and further improve the display unevenness problem of the main display area 100c.
[0080] Combination Figure 4 , Figure 6 as well as Figure 7 , Figure 7 for Figure 1In the second partial schematic diagram of the display device shown, the second signal lines 103 extending to the transition display area 100b are divided into multiple groups, each group is connected in series with the corresponding pixel driving circuit island 101, so that the scanning signal is transmitted to the pixel driving circuit islands 101 connected in series with each other. Each second signal line 103 includes a second connecting section 1031 connecting two adjacent pixel driving circuit islands 101 in the first group of pixel driving circuit islands 101a and the second group of pixel driving circuit islands 101b, and the second connecting section 1031 can be a straight line, a broken line or an arc. Each second signal line 103 also includes a second transition section 1032, and the second transition sections 1032 of the plurality of second signal lines 103 are arranged between the plurality of pixel driving circuit islands 101 and the main display area 100c.
[0081] In the direction from close to the first symmetry axis AA to away from the first symmetry axis AA, the number of second signal lines 103 electrically connected to at least part of the pixel driving circuit islands 101 in the first group of pixel driving circuit islands 101a decreases; in the direction from close to the first symmetry axis AA to away from the first symmetry axis AA, the number of second signal lines 103 electrically connected to at least part of the pixel driving circuit islands 101 in the second group of pixel driving circuit islands 101b decreases to accommodate that part of the pixel driving circuit islands 101 close to the first symmetry axis AA include more second pixel driving circuits 1011, while the pixel driving circuit islands 101 away from the first symmetry axis AA include fewer second pixel driving circuits 1011.

The photosensitive unit is a camera, an optical touch component, an optical fingerprint recognition sensor, etc. Specifically, the photosensitive unit is a camera. The display light-transmitting area 100a has a high light transmittance, which can reduce interference and diffraction of light, and is conducive to improving the photo-taking effect of the electronic device.
