Display panel and display device

A display device, comprising:

• a power supply assembly, and a display panel;
• wherein the power supply assembly is coupled to the display panel and is configured to supply power to the display panel;
• the display panel comprises:
• a base substrate, provided with a special-shaped display region, wherein the special-shaped display region comprises a special-shaped edge region and a main display region, the special-shaped edge region being proximal to a special-shaped edge of the special-shaped display region relative to the main display region;
• a plurality of first pixels, disposed on one side of the base substrate and disposed in the main display region;
• and a plurality of second pixels, disposed on one side of the base substrate and disposed in the special-shaped edge region;
• wherein a number of the plurality of second pixels is smaller than a number of the plurality of first pixels, and each of the plurality of first pixels and the plurality of second pixels comprises:
• a pixel circuit and a light-emitting element, the pixel circuit being coupled to the light-emitting element and being configured to transmit a drive signal to the light-emitting element to drive the light-emitting element to emit light;
• and in a case that the display panel displays a picture of a target gray level, potentials of the drive signals transmitted to the light-emitting elements by the pixel circuits in the second pixels with different distances from the special-shaped edge among the plurality of second pixels are different, and the potential of the drive signal transmitted to the light-emitting element by the pixel circuit in each of the second pixels is smaller than a potential of the drive signal transmitted to the light-emitting element by the pixel circuit in any of the first pixels;
• wherein the plurality of second pixels comprise:
• a plurality of pixel groups, wherein the plurality of pixel groups are sequentially arranged along a direction from the main display region to the special-shaped edge, and distances from the pixel groups to the special-shaped edge are different;
• the second pixels in each of the pixel groups are arranged in a step shape along an extending direction parallel to the special-shaped edge, and distances from the second pixels in each of the pixel groups to the special-shaped edge are equal;
• and in the case that the display panel displays the picture of the target gray level, potentials of the drive signals transmitted to the light-emitting elements by the pixel circuits in the second pixels in each of pixel groups are equal, and the potentials of the drive signals transmitted to the light-emitting elements by the pixel circuits in the second pixels in each of the pixel groups gradually decrease along the direction from the main display region to the special-shaped edge, such that display gray levels of the second pixels gradually decrease:
• wherein in any two adjacent pixel groups, the potentials of the drive signals transmitted to the light-emitting elements by the pixel circuits in the second pixels gradually decrease according to a target decreasing value, such that along the direction from the main display region to the special-shaped edge, in each two adjacent pixel groups, a ratio of display gray levels of the second pixels in one pixel group to display gray levels of the second pixels in the other pixel group is a target ratio.
