Abstract

Light leakage at low gray levels degrades a contrast ratio of LCDs. To increase the contrast ratio, local dimming algorithms have been proposed. In the local dimming algorithms, a dimming duty controls the backlight luminance of each local block, so the dimming duty is to be determined as considering the original image. In this paper, we propose how to determine the dimming duty adaptively which controls the local dimming backlight of LCD devices.
