In addition, the light sensing device may also be a photo detector, a photodiode or other form of sensor that can sense light, and is used to detect various signals in the special-shaped display area 100.
The non-display area 200 is disposed at the periphery of the special-shaped display area 100, that is, the non-display area 200 is an area of the display panel except for the special-shaped display area 100, and is used for disposing a peripheral circuit to control normal display of the special-shaped display area 100, wherein the peripheral circuit may include various power traces, signal traces, a scan driving circuit, and the like.
At least one data line 111, at least one power line 112 and at least one scan line 113 are disposed in the first display region 110, the data lines 111 and the power lines 112 are disposed longitudinally, and the scan lines 113 are disposed transversely to define pixels 500 arranged in an array.

Since the slotted region 300 is disposed above the first display region 110, so that the number of pixels in the first display region 110 is less than the number of pixels in the second display region 120, in this embodiment, at least one compensation capacitor 400 is disposed in the first display region 110, and the compensation capacitor 400 is used to increase a capacitive load on the data line 111 in the first display region 110, thereby ensuring display uniformity of the first display region 110 and the second display region 120.
When the number of the compensation capacitors 400 is plural, the first plates 410 of the compensation capacitors 400 may be disposed on one data line 111, for example: the plurality of compensation capacitors may also be divided into a plurality of groups, each group of compensation capacitors includes one or more compensation capacitors, each group of compensation capacitors is disposed on one of the data lines 111 corresponding to the pixel columns, that is, the first plates of each group of compensation capacitors are respectively electrically connected to the respective data lines 111, and the second plates of each group of compensation capacitors are respectively electrically connected to the respective power lines 112.
For example, four data lines 111 are disposed in the first display area 110, and for convenience of description, the four data lines 111 are sequentially referred to as a first data line, a second data line, a third data line and a fourth data line along a transverse direction of the display panel, i.e., an X direction shown in fig. 1.

Specifically, the capacitance values of the compensation capacitors 400 on each data line 111 may be the same or different, taking the compensation capacitor 400 on the first data line as an example, the capacitance values of the four compensation capacitors on the first data line may be the same or different, that is, the capacitance value of at least one of the four compensation capacitors 400 is different from the capacitance value of the remaining compensation capacitor 400, for example, two of the four compensation capacitors 400 are equal, and for example, the four compensation capacitors 400 are different.

As shown in fig. 3, the compensation capacitor 400 includes a first compensation capacitor 4001 and a second compensation capacitor 4002, and a first plate of the first compensation capacitor 4001 and a first plate of the second compensation capacitor 4002 are electrically connected to the respective data lines 111.

Specifically, the area of the first plate of the first compensation capacitor 4001 and the area of the first plate of the second compensation capacitor 4002 may be set to different values, so that the area of the first plate and the area of the second plate of each compensation capacitor are different, and the capacitance values of the first compensation capacitor 4001 and the second compensation capacitor 4002 are different.
The compensation capacitor 400 can increase the capacitive load on the data line 111 and the power line 112 in the first display region 110, so as to reduce the difference between the load on the data line 111 in the first display region 110 and the load on the data line 111 in the second display region 120, so that under the same driving voltage, the luminance of the pixels in the first display region 110 is the same or substantially the same as that of the pixels in the second display region 120, thereby improving the display uniformity of the display panel.
