  • Publication number: 20250006141
    Abstract: A display device and a display driving method are provided. In a display module, sub-pixels of a same color in adjacent rows are arranged in a staggered manner. The method includes: pre-storing a correspondence between a position of a sub-pixel in a bright-dark boundary region and a corresponding target gray-scale value, wherein a distance between the bright-dark boundary region and a boundary line of bright and dark pixels is within a predefined threshold, the bright and dark pixels are adjacent sub-pixels whose initial gray-scale difference is greater than a first predetermined gray-scale difference, and the correspondence is that the closer the position of the sub-pixel is to the boundary line of the bright and dark pixels, the lower the target gray-scale value is; and determining a current gray-scale value of the sub-pixel in the bright-dark boundary region according to the pre-stored correspondence.
