Abstract

A method for driving a display panel includes obtaining a gray scale value and an abscissa value of a current sub-pixel, compensation gain values and coordinate values of boundary lines of each interval, a gray scale value of a sub-pixel of a previous row; performing a query in a gray scale lookup table according to the gray scale value of the current sub-pixel and the gray scale value of the sub-pixel of the previous row of the display panel to obtain an initial gray scale value of the current sub-pixel, performing a calculating to obtain a gray scale variation compensation value of the current sub-pixel; obtaining an interval of the current sub-pixel located; performing the calculating to obtain a compensation value of the interval of the current sub-pixel located; and obtaining and outputting a final compensation gray scale value of the current sub-pixel by performing a linear interpolation.
