Abstract
Disclosed is a method for obtaining a compensation value of gray scale of a pixel. The method comprises steps of: acquiring a display area of a display panel; dividing the display area equally into a plurality of first sub-areas according to a first preset rule, each of the first sub-areas comprising at least two pixels; obtaining pre-stored multinomial coefficients of each of the first sub-areas, and according to a second preset rule, establishing a multinomial corresponding to each of the first sub-areas; and obtaining a value range of an independent variable of the multinomial, and according to a corresponding multinomial, obtaining a compensation value of gray scale of each of the first sub-areas.
