Claim 0:
1. A method for detecting light leakage of a screen, comprising:
acquiring a brightness value of the screen and grayscale values of pixel points within a preset display region of the screen;
clustering the pixel points based on a plurality of preset grayscale value intervals and the grayscale values of the pixel points, to obtain a plurality of pixel point sets, wherein grayscale values of pixel points in a same pixel point set are in a same grayscale value interval;
obtaining light leakage values corresponding to the pixel point sets based on the brightness value and fused grayscale values corresponding to the pixel point sets, wherein each of the fused grayscale values is obtained by fusing the grayscale values of the pixel points in the pixel point set corresponding to the fused grayscale value; and
obtaining a light leakage value of the screen based on the light leakage values corresponding to the pixel point sets.
