Abstract

The present disclosure belongs to the field of display technologies, and provides a method and apparatus for compensating white point coordinates, and a computer device and a storage medium. The method includes: acquiring target brightness and target white point coordinates of a display module in a black frame insertion mode, wherein the display module includes a backlight; determining white point coordinates corresponding to the target brightness to be reached by the backlight in the black frame insertion mode and in an always-on mode, respectively; and compensating the target white point coordinates based on a difference value between the white point coordinates in the always-on mode and the white point coordinates in the black frame insertion mode.
