Abstract
A method includes: measuring a duration of the high level of a frame start signal of a display device; calculating a current driving frequency for the display device based on the duration of the high level; updating a chromaticity coordinate accuracy lookup table for a predetermined target grayscale when the current driving frequency is lower than a preset threshold; and adjusting luminance of the display device based on the updated chromaticity coordinate accuracy lookup table.
