1. A method for compensating white point coordinates, comprising:
acquiring target brightness and target white point coordinates of a display module in a black frame insertion mode, wherein the display module comprises 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 model;
wherein the compensating the target white point coordinates based on the difference value between the white point coordinates in the always-on mode and the white point coordinates in the black frame insertion mode comprises:
acquiring the compensated target white point coordinates by adding a product of a difference value between the white point coordinates in the black frame insertion mode and the white point coordinates in the always-on mode and a compensation proportion coefficient to the target white point coordinates.
