Referring to fig. 5, the display panel 10 further includes M-M compensation circuits 400. Each of the compensation circuits 400 is electrically connected to one of the second scan lines 320.
The compensation circuit 400 may be configured according to the load on the second scan line 320 to be compensated. The size of the compensation circuit 400 to be compensated may also be different if the number of the pixel units 201 electrically connected to the second scan line 320 is different. In one embodiment, each of the compensation circuits 400 includes one or more of a compensation line, a compensation capacitor, a compensation resistor, and a compensation pixel cell. The arrangement form of the compensation circuit 400 is not particularly limited. The pixel compensation unit may be configured to include only the TFT and not the OLED.

Each of the second scan lines 320 electrically connects the Y-th one of the pixel cells 201 of each of the first pixel cell columns 211 and the Y-th one of the pixel cells 201 of each of the third pixel cell columns 231. The display panel 10 redefines the first scan line 310 and the second scan line 320. The display panel 10 moves down the wiring of the special-shaped area entirely, so that the stacking of scanning lines near the special-shaped area is avoided, and the display uniformity of the display panel 10 entirely is better.
In this embodiment, the display panel 10 further includes the compensation circuit 400. The compensation circuit 400 is capable of compensating the load on the second scan line 320 such that the load of the first scan line 310 and the second scan line 320 is the same or within an allowable error range. The scan driving circuit 500 may drive the first scan line 310 and the second scan line 320 with a uniform signal, so that the display uniformity of the display panel 10 as a whole is better.
Referring again to fig. 4 and 5, in one embodiment, the display panel 10 further includes a scan driving circuit 500. The scan driving circuit 500 is disposed on the substrate 101 and electrically connected to the plurality of first scan lines 310 and the plurality of second scan lines 320, respectively.

In this embodiment, the scan driving circuit 500 is configured to drive the plurality of pixel circuits 201 electrically connected to each of the first scan line 310 and the second scan line 320. The specific structure and specific position arrangement of the driving circuit 500 may be arbitrary. Specifically, the scan driving circuit 500 may perform the same driving on each of the first scan lines 310 and each of the second scan lines 320. When the driving signals are loaded on the first scan line 310 and the second scan line 320, the delay of the signals reaching each pixel unit 201 is the same, so that the display uniformity of the display panel 10 can be improved.
Referring again to fig. 5, in one embodiment, the scan driving circuit 500 includes a first scan driving circuit 510 and a second scan driving circuit 520.
The first scan driving circuit 510 is electrically connected to one ends of the first scan lines 310 and one ends of the second scan lines 320, respectively.

In this embodiment, two of the scan driving circuits 500 are provided. The first scan driving circuit 510 and the second scan driving circuit 520 may have different structures. The driving currents outputted from the first scan driving circuit 510 and the second scan driving circuit 520 may be different. The first scan driving circuit 510 and the second scan driving circuit 520 are arranged such that the driving current obtained by each of the pixel units 201 can be greater and the speed of driving the display panel 10 can be faster.

The number of the pixel units 201 electrically connected to each of the first data lines 610 is the same. The number of the pixel units 201 electrically connected to the second data line 620 may be the same or different. For example, when a plurality of the second data lines 620 are electrically connected to a plurality of the pixel cells 201 in the second pixel cell column 221, the number of the pixel cells 201 to which the plurality of the second data lines 620 are connected is the same. When a plurality of the second data lines 620 are electrically connected to a plurality of the pixel cells 201 in the third pixel cell column 231, the number of the pixel cells 201 to which the plurality of the second data lines 620 are connected is not the same.
In this embodiment, the first data line 610 does not need to be load-compensated. The second data line 620 may be load compensated. In the compensation of the data lines, the data driving circuit may be used to compensate the second data lines so that the brightness of the display of each pixel unit 201 in the display panel 10 is uniform.

For example, the data driving circuit 700 may apply a larger data driving signal to the first data line 610. The data driving circuit 700 may apply a slightly smaller data driving signal to the second data line 620. The application of the different data driving signals by the data driving circuit 700 may enable the pixel units 201 on the display panel 10 to be uniformly lighted.
Referring to fig. 4-6, in one embodiment, the display panel 10 further includes a wiring portion 240. The wiring portion 240 is located on the substrate 101 and is used for carrying a plurality of compensation circuits 400.
