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.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic plan view of a display device according to an embodiment of the present disclosure, and fig. 2 is a schematic distribution diagram of first display pixels and second display pixels in the display device shown in fig. 1. The display device 100 has a display transmissive area 100a, a main display area 100c, and a transition display area 100 b. 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.
The transition display area 100b is disposed between the display transmissive area 100a and the main display area 100 c. Both the main display area 100c and the transition display area 100b are used for display. The display light-transmitting region 100a is used for display and has high light-transmitting characteristics. The light transmittance of the display light-transmitting area 100a is greater than the light transmittance of the main display area 100c and the transition display area 100 b. The area of the main display region 100c is larger than the area of the transitional display region 100b and the area of the display transmissive region 100 a.
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 shape. The transition display area 100b is annular. The transition display area 100b is any one of an elliptical ring shape, a circular ring shape, or a square ring shape.
Specifically, the display light-transmitting area 100a is circular. The light-transmitting regions 100a are shown to be symmetrically disposed about a first axis of symmetry a-a and a second axis of symmetry B-B, the first axis of symmetry a-a being perpendicular to the second axis of symmetry B-B. The transitional display area 100b has a ring shape, and the boundary of the transitional display area 100b near the display transmissive area 100a has a circular shape.
The plurality of first display pixels are uniformly disposed in the main display area 100c, and each of the first display pixels includes a first red sub-pixel 100c1, a first green sub-pixel 100c3, and a first blue sub-pixel 100c 2. The first red sub-pixel 100c1, the first green sub-pixel 100c3 and the first blue sub-pixel 100c2 are disposed in a Pentile design in the main display area 100 c. The first green sub-pixel 100c3 has an elliptical shape, and the first red sub-pixel 100c1 and the first blue sub-pixel 100c2 have an octagonal shape.
A plurality of first pixel driving circuits are also disposed in the main display area 100 c. One first pixel driving circuit correspondingly drives one sub-pixel (one of the first red sub-pixel 100c1, the first green sub-pixel 100c3 and the first blue sub-pixel 100c 2) of the main display area 100c to emit light. The first pixel driving circuit may employ any one of common 7T1C, 6T1C, 5T1C, 4T1C, 3T1C, and 2T 1C. Each of the first pixel driving circuits includes a plurality of metal film layers, and the plurality of first pixel driving circuits are disposed in the main display area 100c in an array, resulting in a low light transmittance of the main display area 100 c.
The plurality of second display pixels are uniformly disposed in the display transmissive region 100a and the transition display region 100 b. Each second display pixel includes a second red subpixel 100a1, a second green subpixel 100a3, and a second blue subpixel 100a 2. The second red sub-pixel 100a1, the second green sub-pixel 100a3, and the second blue sub-pixel 100a2 are disposed in a Pentile design in the display transparent area 100a and the transition display area 100 b. The shapes of the second red sub-pixel 100a1, the second green sub-pixel 100a3, and the second blue sub-pixel 100a2 are all circular.
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 light transmittance. Since the sizes of the second red sub-pixel 100a1 and the first red sub-pixel 100c1 are different, and the driving powers of the driving circuits corresponding to the second red sub-pixel and the first red sub-pixel are different, and similarly, the driving powers of the first green sub-pixel 100c3 and the second green sub-pixel 100a3 are different, and the driving powers of the first blue sub-pixel 100c2 and the second blue sub-pixel 100a2 are different, the first pixel driving circuit can only be used for driving 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, but cannot be used for driving the second red sub-pixel 100a1, the second green sub-pixel 100a3, and the second blue sub-pixel 100a2 of the transition display area 100b and the display transparent area 100 a. From the main display area 100c to the transition display area 100b, the size of the sub-pixels becomes smaller.

The second pixel driving circuit 1011 in the pixel driving circuit island 101 is electrically connected to the second display pixel in the display transparent area 100a through a transparent conductive wire, so as to further improve the light transmittance of the display transparent area 100 a. The transparent conducting wire is made of at least one material selected from indium tin oxide and indium zinc oxide. The second pixel driving circuits 1011 in the pixel driving circuit island 101 and the second display pixels in the transitional display area 100b may be electrically connected through metal wires.
The pixel driving circuit island 101 is a structure in which a plurality of second pixel driving circuits 1011 are collectively arranged. The pitch between two adjacent pixel driving circuit islands 101 is larger than the pitch between two adjacent second pixel driving circuits 1011.
Unlike in the main display area 100c, one second pixel driving circuit 1011 may 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, to reduce the number of second pixel driving circuits 1011, to reduce the space occupied by the pixel driving circuit islands 101, so that the size of the display light-transmitting area 100a may be increased or the display area 100b may have too much 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 among the plurality of second red sub-pixels 100a1, the plurality of second green sub-pixels 100a3, and the plurality of second blue sub-pixels 100a 2. In the display transparent area 100a, the sub-pixels driven by the same second pixel driving circuit 1011 are electrically connected through transparent wires.
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.
The plurality of first signal lines 102 extend from the main display area 100c to the transitional display area 100b, the plurality of second signal lines 103 extend from the main display area 100c to the transitional display area 100b, and the plurality of first signal lines 102 and the plurality of second signal lines 103 are not disposed in the display transparent area 100 a. The plurality of first signal lines 102 and the plurality of second signal lines 103 are made of a metal, including but 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 disposed in the display transparent area 100a, so as to further improve the light transmittance of the display transparent area 100 a.
Specifically, the first signal line 102 is a data line for transmitting a data signal. The second signal line 103 is selected from at least one of a scan line for transmitting a scan signal, a reset line for transmitting a reset signal and/or an initialization signal, and a light emission control signal line for transmitting a light emission control signal.
In the main display area 100c, the plurality of first signal lines 102 perpendicularly intersect the plurality of second signal lines 103, the plurality of first signal lines 102 are parallel to each other and the distance between any two adjacent first signal lines 102 is equal, the plurality of second signal lines 103 are parallel to each other and the distance between any two adjacent second signal lines 103 is equal, and the plurality of second signal lines 103 perpendicularly intersect the plurality of first signal lines 102.
In the transitional display area 100b, the plurality of second pixel driving circuits 1011 form a plurality of pixel driving circuit islands 101, each pixel driving circuit island 101 is electrically connected to at least two of the plurality of first signal lines 102 and at least two of the plurality of second signal lines 103, so that the plurality of first signal lines 102 need to be adjusted and divided into a plurality of groups of first signal lines 102 when extending to the transitional display area 100b, each group of first signal lines 102 is connected to one pixel driving circuit island 101, and the plurality of second signal lines 103 need to be changed and divided into a plurality of groups when extending to the transitional display area 100b, each group of second signal lines 103 is connected in series with the plurality of pixel driving circuit islands 101.
As shown in fig. 3 and 4, each of the first signal lines 102 includes a first connection section 1021, the first connection sections 1021 of the first signal lines 102 are connected to the pixel driving circuit islands 101, so that the data signals are transmitted to the second pixel driving circuits 1011 of the pixel driving circuit islands 101, and the first connection sections 1021 of the first signal lines 102 are disposed between the pixel driving circuit islands 101 and the display transparent area 100 a.
Compared with the chinese patent publication No. CN110491917A, when the second roundabout segments of the second signal lines are disposed at the periphery of the pixel driving circuit island, the complexity of wiring is increased when the second roundabout segments of the second signal lines need to be connected to the corresponding pixel driving circuit island by wire replacement, and the longer length of the second roundabout segments of the second signal lines may cause the impedance difference between the second signal lines having the second roundabout segments and the second signal lines in the main display area to be larger, resulting in the problem of uneven display in the main display area. The first connecting sections 1021 of the first signal lines 102 are arranged between the pixel driving circuit islands 101 and the display transparent area 100a, so that the first connecting sections 1021 of the first signal lines 102 can be directly connected with the corresponding pixel driving circuit islands 101 without changing the lines, the wiring complexity of the first connecting sections 1021 of the first signal lines 102 is reduced, the first connecting sections 1021 of the first signal lines 102 are arranged between the pixel driving circuit islands 101 and the display transparent area 100a, the length of the first connecting sections 1021 of the first signal lines 102 is reduced, the problem that the impedance difference between the first signal lines 102 with the first connecting sections 1021 and the first signal lines of the main display area 100c is large due to the fact that the length of the first connecting sections 1021 of the first signal lines 102 is too long is solved, and therefore the problem that the impedance difference between pixels connected with the first signal lines 102 with the first connecting sections 1021 and pixels connected with linear first signal lines in the main display area 100c is improved The problem of uneven display.

In one aspect, the first transition 1022 of a portion of the first signal lines 102 is adjusted relative to the first signal lines 102 of the main display area 100c to adapt to the difference existing when the first signal lines 102 are respectively connected to the first pixel driving circuits of the main display area 100c and the pixel driving circuit islands 101 of the transition display area 100b, and the first transition 1022 needs to occupy the space between the plurality of pixel driving circuit islands 101 and the main display area 100c for adjustment to connect to the plurality of pixel driving circuit islands 101. On the other hand, the plurality of pixel driving circuit islands 101 are disposed closer to the center position of the display transparent area 100c, ensuring that the second pixel driving circuits 1011 in the pixel driving circuit island 101 of the second display pixel corresponding to the center position of the display transparent area 100a can drive the second display pixel at the center position.
At least a portion of the first transition sections 1022 includes a fan-shaped section 10221 and a straight-line section 10222 connected to the fan-shaped section 10221, the fan-shaped sections 10221 of the plurality of first transition sections 1022 are gathered and distributed in a fan shape, narrow down to form a group of first signal lines 102, and are connected to the pixel driving circuit island 101 through the straight-line sections 10222 of the plurality of first transition sections 1022.
The plurality of pixel driving circuit islands 101 are distributed around the display transparent area 100a, so that the plurality of pixel driving circuit islands 101 are arranged to adapt to the shape of the display transparent area 100a, and the distance between the second pixel driving circuit 1011 in the plurality of pixel driving circuit islands 101 and the corresponding sub-pixel is reduced, thereby reducing the impedance of a wire connecting the second pixel driving circuit 1011 and the corresponding sub-pixel, and improving the uniformity of light emission of the second display pixel.

The pixel drive circuit islands 101 in the second group of pixel drive circuit islands 101b are symmetrically arranged about the first axis of symmetry a-a. The connection segment of each first signal line 102 is connected between the pixel drive circuit island 101 in the first group of pixel drive circuit islands 101a and the corresponding pixel drive circuit island 101 in the second group of pixel drive circuit islands 101b, so that a data signal is transmitted between the pixel drive circuit island 101 in the first group of pixel drive circuit islands 101a and the corresponding pixel drive circuit island 101 in the second group of pixel drive circuit islands 101 b.
