Abstract

This work proposes an online DVS approach for OLED-based mobile video applications to reduce display power consumption. A time-efficient representative-region based DVS scheme is developed and applied in MPEG video streaming. Based on the proposed scheme, flexible DVS solutions can be adaptively derived according to timing constraints. Experimental results show a 26.9% power reduction while keeping 99.3% frames displayed in high quality.
