Abstract
A display driver is provided. The display driver includes an OPR generating module, a brightness limiting module and a driving module. The OPR generating module is configured to generate a reference OPR corresponding to an image; the brightness limiting module is configured to acquire a plurality of brightness ranges and an initial brightness value corresponding to the image, one brightness range corresponding to one OPR range; the brightness limiting module is further configured to acquire a reduced brightness value corresponding to the reference OPR by performing interpolation at the reference OPR based on the initial brightness value, the plurality of brightness ranges and OPR ranges corresponding to the plurality of brightness ranges, the reduced brightness value being smaller than the initial brightness value; and the driving module is configured to drive the display panel to display the image based on the reference OPR and the reduced brightness value.
