As shown in fig. 2 and fig. 3, the display panel includes a display area 100, a plurality of sub-pixels 300 are disposed in the display area 100, the plurality of sub-pixels 300 are arranged in a plurality of sub-pixel rows 310, and an extending direction of the sub-pixel rows 310 is a first direction X.
The display area 100 includes a first display area 110 and a second display area 120, a density of the sub-pixels 300 in the first display area 110 is less than a density of the sub-pixels 300 in the second display area 120, the first display area 110 includes a plurality of island-shaped first sub-display areas 111 and a first sub-non-display area 112 disposed around the first sub-display areas 111, and the plurality of sub-pixels 300 in the first display area 110 are located in the first sub-display areas 111.

It should be noted that in the overall panel design, the optical element may be disposed in the first display region 110 with lower density of the sub-pixels, so that the optical element can receive more light, and further achieve better device performance.
It should be noted that, to simplify the structure of the drawings, fig. 2 and 3 only illustrate the first connecting wires 410 between the sub-pixels 300 and the corresponding first signal lines 210 in the first display area 110, and do not illustrate the connecting wires between the sub-pixels 300 and the corresponding first signal lines 210 in the second display area 120, specifically, in the orientation shown in fig. 2 and 3, the sub-pixels 300 in the second display area 120 are electrically connected to the first signal lines 210 on the lower side thereof.
For example, the first connection wires 410 in the first display area 110 may include at least two different arrangements, as shown in fig. 2 and 3, respectively. In fig. 2, the sub-pixels 300 arranged in the same row in the first sub-display area 111 are electrically connected to the corresponding first signal lines 210 by a common conductive line; in fig. 3, each sub-pixel 300 in the first sub-display area 111 is electrically connected to the corresponding first signal line 210 through an independent conductive line. The arrangement of the first connecting wires 410 is merely exemplary and not limited, and in other embodiments of the present embodiment, the first connecting wires 410 may also adopt other arrangements that can electrically connect the sub-pixels 300 and the corresponding first signal lines 210. For example, as shown in fig. 4, on the basis of the arrangement shown in fig. 2, the common conductive line electrically connected to the sub-pixels 300 in the same row in the first sub-display area 111 may also have two ends electrically connected to the corresponding first signal lines 210, so as to reduce the influence of the voltage drop on the common conductive line on the brightness uniformity of the sub-pixels 300 in the same row.
In the first display area 110, the sub-pixels 300 are distributed in the first sub-display area 111 in a concentrated manner, the sub-pixels 300 are not included in the first non-sub-display area 112, and only the connecting lines between the adjacent sub-pixels 300 are provided, so that the first sub-non-display area 112 is a main light transmission area of the first display area 110, and the light blocking structure in the first sub-non-display area 112 is less, and the light transmittance of the first display area 110 is higher. In the present embodiment, the n rows of sub-pixels 300 in the first sub-display area 111 are electrically connected to one first signal line 210, and the first connecting wire 410 is disposed in the first sub-display area 111, so that the n rows of sub-pixels 300 in the first sub-display area 111 only correspond to one first signal line 210 in the first sub-non-display area 112, compared with the prior art in which each row of sub-pixels 300 in the first sub-display area 111 corresponds to one first signal line 210 in the first sub-non-display area 112, in the technical scheme provided in the present embodiment, the number of first signal lines 210 in the first sub-non-display area 112 is significantly reduced, the light blocking structure in the first sub-non-display area 112 is reduced, and the light transmittance of the first display area 110 is increased. It is understood that the first connecting wire 410 is a necessary arrangement for electrically connecting the same first signal line 210 to each n rows of sub-pixels 300, and the light-shielding first connecting wire 410 is disposed in the first sub-display region 111 to prevent it from affecting the light transmittance of the first sub-non-display region 112.
The present embodiment does not limit the specific arrangement of the sub-pixels 300 in the display area 100. For example, as shown in fig. 2 to 4, the odd sub-pixel rows and the even sub-pixel rows may be arranged in a staggered manner; as shown in fig. 5 to 7, the sub-pixels 300 in the display area 100 may be arranged in a matrix.
The structures of the display panel shown in fig. 1 to 7 are only examples, and are not limited to the number of the first sub display regions 111, the positional relationship between the first sub non display regions 111, the number and arrangement of the sub pixels 300 in the first sub non display regions 111, and the like.
Fig. 8 is a schematic structural diagram of another display panel according to an embodiment of the present invention. On the basis of the display panel shown in fig. 2, the plurality of signal lines 200 in the display panel shown in fig. 8 further include a plurality of second signal lines 220, the plurality of sub-pixels 300 electrically connected to the same first signal line 210 are electrically connected to the same second signal line 220, and a plurality of second connecting wires 420 for electrically connecting the sub-pixels 300 and the corresponding second signal lines 220 are located in the first sub-display regions 111.
In addition, the plurality of signal lines 200 in the display panel shown in fig. 3 to 7 may also include a plurality of second signal lines 220, and the specific structure can be seen in fig. 9 to 13, respectively.
It should be noted that, in the above-mentioned arrangement manner, on the basis of electrically connecting one first signal line 210 to n rows of sub-pixels 300 in the first sub-display area 111, one second signal line 220 is electrically connected, and the second connection wire 420 is arranged in the first sub-display area 111, and then the n rows of sub-pixels 300 in the first sub-display area 111 only correspond to one second signal line 220 in the first sub-non-display area 112, compared with the arrangement manner in the prior art that each row of sub-pixels 300 in the first sub-display area 111 corresponds to one second signal line 220 in the first sub-non-display area 112, in the technical solution provided in this embodiment, the number of second signal lines 220 in the first sub-non-display area 112 is significantly reduced, the light blocking structure in the first sub-non-display area 112 is further reduced, and the light transmittance of the first display area 110 is further increased. It is understood that the second connecting wire 420 is a necessary arrangement for electrically connecting the same second signal line 220 to the sub-pixels 300 of every n rows, and the light-shielding second connecting wire 420 is arranged in the first sub-display region 111 to prevent it from affecting the light transmittance of the first sub-non-display region 112.
Further, on the basis of the display panel structures shown in fig. 8 to 13, the plurality of signal lines 200 further include a plurality of third signal lines 230, the plurality of sub-pixels 300 electrically connected to the same first signal line 210 are electrically connected to the same third signal line 230, and a plurality of third connecting wires 430 for electrically connecting the sub-pixels 300 and the corresponding third signal lines 230 are located in the first sub-display regions 111, and specific structures can be seen in fig. 14 to 19, respectively.
It should be noted that, in the above-mentioned arrangement manner, the n rows of sub-pixels 300 in the first sub-display area 111 are electrically connected to one third signal line 230 on the basis of electrically connecting one first signal line 210 and one second signal line 220, and the third connecting wire 430 is arranged in the first sub-display area 111, and further the n rows of sub-pixels 300 in the first sub-display area 111 correspond to only one third signal line 230 in the first sub-non-display area 112, compared with the arrangement manner in the prior art that each row of sub-pixels 300 in the first sub-display area 111 corresponds to one third signal line 230 in the first sub-non-display area 112, in the technical solution provided in this embodiment, the number of third signal lines 230 in the first sub-non-display area 112 is significantly reduced, the light blocking structure in the first sub-non-display area 112 is further reduced, and the light transmittance of the first display area 110 is further increased. It is understood that the third connecting conductive line 430 is a necessary arrangement for electrically connecting the same third signal line 230 to the sub-pixels 300 of every n rows, and the light-shielding third connecting conductive line 430 is disposed in the first sub-display region 111 to prevent it from affecting the light transmittance of the first sub-non-display region 112.
Illustratively, the first signal line 210, the second signal line 220, and the third signal line 230 are each any one of a scan line, a light emission driving signal line, and a reset signal line, and are different from each other.
In the organic light emitting display panel, the corresponding sub-pixels 300 are usually driven to emit light by a driving circuit such as 7T1C, and the adjacent n rows of sub-pixels 300 can share the same scanning signal, light emitting driving signal and reset signal, so the first signal line 210, the second signal line 220 and the third signal line 230 are respectively arranged as any one of the scanning line, the light emitting driving signal line and the reset signal line, and are different from each other, and the sharing of three different signals can achieve the beneficial effect of simplifying the driving signal on the basis of ensuring the normal operation of the driving circuit.
It can be understood that, according to the difference of the sub-pixel driving circuit, the number and the kind of the signal lines that can be shared by each adjacent n rows of sub-pixels 300 are different, in this embodiment, only the first signal line 210, the second signal line 220, and the third signal line 230 are shared by each adjacent n rows of sub-pixels 300, the first signal line 210, the second signal line 220, and the third signal line 230 are any one of the scanning line, the light-emitting driving signal line, and the reset signal line, respectively, and are different by way of example and not limitation, and a designer can reasonably set the number and the kind of the signal lines that can be shared by each adjacent n rows of sub-pixels 300 according to actual needs.
As shown in fig. 18, in the first sub-display area 111, each sub-pixel 300 is connected to the corresponding first signal line 210, second signal line 220 and third signal line 230 through one first connecting wire 410, one second connecting wire 420 and one third connecting wire 430, respectively.
It should be noted that, the process implementation difficulty of the above arrangement is low, and the lengths of the first connecting wire 410, the second connecting wire 420 and the third connecting wire 430 are smaller, so that the area occupied by the first sub-display region 111 is smaller, which is beneficial to increase the area of the first sub-non-display region 112, and is further beneficial to increase the light transmittance of the first display region 110.
With continued reference to fig. 17 and 19, the plurality of first connection wires 410 includes a plurality of first common wires 411 and a plurality of first single wires 412, the plurality of second connection wires 420 includes a plurality of second common wires 421 and a plurality of second single wires 422, and the plurality of third connection wires 430 includes a plurality of third common wires 431 and a plurality of third single wires 432. In each adjacent n rows of sub-pixels 300, any one row of sub-pixels 300 forms a first sub-pixel row 311, the rest of sub-pixels form n-1 second sub-pixel rows 312, and in the first sub-pixel row 311, each sub-pixel 300 is connected with the corresponding first signal line 210, the second signal line 220 and the third signal line 230 through a first single conducting wire 412, a second single conducting wire 422 and a third single conducting wire 432 respectively. Each second sub-pixel row 312 corresponds to one first common conductive line 411, one second common conductive line 421 and one third common conductive line 431, the first common conductive line 411, the second common conductive line 421 and the third common conductive line 431 are respectively connected with the corresponding first signal line 210, the second signal line 220 and the third signal line 230, and in the second sub-pixel row 312, the sub-pixels 300 are respectively connected with the corresponding first common conductive line 411, the second common conductive line 421 and the third common conductive line 431 through one first single conductive line 412, one second single conductive line 422 and one third single conductive line 432.
It should be noted that, by such an arrangement mode, the arrangement modes of the first single conductive line 412, the second single conductive line 422, and the third single conductive line 432 corresponding to each sub-pixel 300 in the first display area 110 can be the same, and further, the same process and parameters can be used for formation, and a special design for a specific sub-pixel 300 is not required, which is beneficial to reducing the design difficulty and the process difficulty of the display panel. And the first common conductive line 411, the second common conductive line 421 and the third common conductive line 431 are convenient to route between adjacent sub-pixels 300, and the pixel aperture ratio of the display panel is not reduced.
In this embodiment, the display panel may further include a plurality of driving circuits, each of the driving circuits is electrically connected to one of the sub-pixels, and each of the driving circuits includes a thin film transistor and a storage capacitor. Specifically, fig. 20 is a schematic cross-sectional structure diagram of a display panel according to an embodiment of the present invention. As shown in fig. 20, the gate 510 of the thin film transistor 500 in the driving circuit is located in the first metal layer, and the electrode 600 of the storage capacitor far away from the corresponding sub-pixel 300 is located in the second metal layer. Any two adjacent signal lines of the first signal lines 210, the second signal lines 220, and the third signal lines 230 are disposed on the first metal layer and the second metal layer, respectively.
It should be noted that the first signal line 210, the second signal line 220, and the third signal line 230 corresponding to each sub-pixel row 310 are disposed in a gap between the sub-pixel row 310 and an adjacent sub-pixel row 310, and it is noted that any two adjacent signal lines include two signal lines respectively located at two opposite sides of the same sub-pixel row 310, and for example, in fig. 20, the third signal line 230 located between the first sub-pixel 301 and the second sub-pixel 302 and the first signal line 210 located between the second sub-pixel 302 and the third sub-pixel 303 belong to two adjacent signal lines.

It should be noted that, the conventional display panel includes red, green and blue sub-pixels, and a pixel unit is composed of the red sub-pixel, the blue sub-pixel and the green sub-pixel, and in the pixel unit, red light, green light and blue light emitted by the three sub-pixels with different colors are mixed to obtain target white light. In this embodiment, the distance between adjacent first sub-display regions 111 is relatively large, and it is difficult for the light emitted by the sub-pixel 300 in any first sub-display region 111 to mix with the light emitted by the sub-pixel 300 in the adjacent first sub-display region 111 to obtain the target white light, so that, to avoid the color cast phenomenon, the number of columns of the sub-pixels 300 in the first sub-display region 111 is set to be a multiple of 3, so that each first sub-display region 111 includes an integer number of pixel units.
In addition, the total number of the sub-pixel rows 310 in the display panel may be an integer multiple of p, so that the connection manner of each adjacent n rows of sub-pixels 300 is completely the same, which is convenient for design.
