Grayscale compensation method, apparatus and system, display driving method, apparatus and system, and chip and medium

Abstract

A grayscale compensating method, a displaying driving method, an apparatus, a system, a chip and a medium. The grayscale compensating method includes: determining compensation coefficients corresponding to a plurality of sub-pixels in a display panel, wherein the compensation coefficients are for characterizing the compensation modes and the compensation magnitudes of brightness compensations to the sub-pixels, wherein the compensation modes include the mode of increasing the brightness and the mode of reducing the brightness; based on the compensation coefficients and to-be-displayed grayscale values corresponding to the sub-pixels, determining correction coefficients corresponding to the plurality of sub-pixels, wherein unequal to-be-displayed grayscale values correspond to unequal correction coefficients, and the correction coefficients are for correcting the compensation magnitudes; and based on the compensation coefficients and the correction coefficients, compensating for the to-be-displayed grayscale values of the plurality of sub-pixels, to reduce the difference in the emitted-light brightnesses of the plurality of sub-pixels.
