  • Publication number: 20240169878
    Abstract: The present application provides a display panel and a grayscale compensation method. The grayscale compensation method first divides a display area of the display panel into a first display sub-area and a second display sub-area, and then takes average brightness of the at least one second display sub-area as target brightness and compensates a grayscale of each sub-pixel in the at least one second display sub-area. Accordingly, the present application not only improves the brightness uniformity of the display area, but also requires less gray scale compensation data.
