Abstract
The present disclosure provides a compensation method, compensation device, and a display device. The compensation method includes: adjusting charging time for multiple areas of the display screen so that the charging time for each area is positively related to a distance from the area to a data voltage input terminal; comparing a first grayscale value before compensation of a sub-pixel in an i-th row and j-th column with a second grayscale value input to a sub-pixel in an (i−1)-th row and j-th column; searching a corresponding grayscale compensation parameter from a grayscale compensation parameter table according to the first grayscale value and the second grayscale value; compensating the first grayscale value by the grayscale compensation parameter to obtain a third grayscale value; and inputting the third grayscale value to the sub-pixel in the i-th row and j-th column for display.
