Abstract

In this paper, we present algorithms for the calculation of local dimming LED-Backlight. They assure clipper-free results and can be implemented at low HWcosts. The power saving is in average 38.7% compared to global dimming. For a XGA display 72K (RGB) logic gates are needed to implement this algorithm on chip.
