Abstract
A display compensation module, a display compensation method and a display device are provided. The display compensation module includes a search circuit, a compensation control circuit and a compensation circuit. The search circuit is configured to obtain compensation information corresponding to the display gray-scale value of the M-th row in the N-th frame of display data and the display gray-scale value of the M-th row in the (N−1)-th frame of display data, and when the compensation information indicates that the display gray-scale values of at least part of columns of sub-pixels in the M-th row in the display panel increase from the (N−1)-th frame to the N-th frame, apply the first control signal to the compensation control circuit; N is an integer greater than 1, M is a positive integer. The compensation control circuit is configured to: determine whether to perform a gray-scale compensation according to the display gray-scale value of the M-th row in the N-th frame of display data after receiving a first control signal. The compensation circuit is configured to compensate the display gray-scale value of the M-th row in the N-th frame of display data after receiving the compensation control signal.
