US 2024/0203314 A1 · METHOD AND APPARATUS FOR DRIVING DISPLAY PANEL AND DISPLAY DEVICE

Abstract

The present disclosure provides a driving method of a display panel, including: determining a target region and a non-target region in the display panel; dividing the target region into a plurality of target sub-regions, and dividing the non-target region into a plurality of non-target sub-regions, wherein an area of the target sub-region is less than that of the non-target sub-region; determining brightness compensation values of each target sub-region and each non-target sub-region according to a gray scale value of each pixel in an input image; determining a compensated brightness of each pixel unit in the display panel according to the gray scale value of each pixel in the input image, the brightness compensation values of each target sub-region and each non-target sub-region; and driving each pixel unit in the display panel to emit light according to the compensated brightness of each pixel unit in the display panel.
