Abstract

Provided is a method for determining grayscale data. The method for determining grayscale data includes acquiring a source image; acquiring pixel values of third pixel points by calculating weighted values of channel values of a first pixel point and channel values of second pixel points of corresponding colors; acquiring a first image by replacing pixel values of the second pixel points in the source image with the pixel values of the third pixel points; and determining grayscale data of the first panel and grayscale data of the second panel based on the first image.
