Abstract
A driving method of a display panel includes: determining a brightness band of the display panel, wherein brightness bands include a first brightness band to an Nth brightness band, maximum grayscale brightness of the first brightness band to the Nth brightness band decreases sequentially, and each brightness band includes three Gamma correction curves respectively corresponding to a first light emitting unit, a second light emitting unit, and a third light emitting unit each of an (N−M)th brightness band to the Nth brightness band also corresponds to at least one duty ratio; determining an input data voltage corresponding to at least one light emitting unit based on a Gamma correction curve that corresponds to the determined brightness band and an image to be displayed; and driving the display panel to display the image based on the determined input data voltage, or the determined input data voltage and the duty ratio.
