Abstract
Provided is a method for determining a compensation grayscale value of a display panel. The method includes searching, in a table of grayscale bit number judgment values, for a grayscale bit number judgment value corresponding to a sub-pixel to be compensated; determining a compensation grayscale value corresponding to the sub-pixel to be compensated by a first reading process if the grayscale bit number judgment value satisfies a grayscale bit number condition, and determining the compensation grayscale value corresponding to the sub-pixel to be compensated by a second reading process if the grayscale bit number judgment value does not satisfy the grayscale bit number condition.
