Abstract
A display driver includes a display panel, a backlight array, and backlight control circuitry. The backlight array includes a plurality of light sources and is configured to illuminate the display panel. The backlight control circuitry is configured to determine first base luminance for a first light source of the plurality of light sources based at least in part on pixel data for a first set of pixels associated with the first light source. The backlight control circuitry is further configured to determine first compensated luminance for the first light source by modifying the first base luminance based at least in part on a position of the first light source in the backlight array. The backlight control circuitry is further configured to control light emission of the first light source based at least in part on the first compensated luminance.
