Abstract: A compensation method for a display area with an under-display camera includes acquiring the attenuation compensation amount of each sub-pixel between each of sub-pixels of the display area with the under-display camera and each of sub-pixels of a non-display area without the under-display camera in a display screen at the current moment, where the sub-pixels include a red sub-pixel, a green sub-pixel, and a blue sub-pixel; acquiring the attenuation accumulation amount of each sub-pixel of each pixel in the display area with the under-display camera; determining the pixel compensation amount of each sub-pixel of each pixel in the display area with the under-display camera according to the attenuation compensation amount and the attenuation accumulation amount; and compensating each sub-pixel of each pixel in the display area with the under-display camera according to the pixel compensation amount.
