  • Publication number: 20250078751
    Abstract: Provided is a display panel. The display panel includes a base substrate, a plurality of first pixels, and a plurality of second pixels. The base substrate is provided with a special-shaped display region, and the special-shaped display region includes a special-shaped edge region and a main display region which are sequentially arranged along the direction distal from the special-shaped edge. The first pixels are disposed in the main display region. The second pixels are disposed in the special-shaped edge region. In the case that the display panel displays a picture of a target gray level, the 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 are different and are smaller than the potentials of the drive signals transmitted to the light-emitting elements by the pixel circuits in the first pixels.
