Abstract :
As one of the next generation display panel, active matrix organic light emitting diodes (AMOLED) had been widely employed for the multimedia platforms. However, AMOLED is rapidly increase power consumption when fullwhite color expression. Therefore, the lifetime of panel is decline. In this paper, we propose the enhancement net power control algorithm that makes use of the local power control and the global power control respectively based pixel by pixel and frame operation was presented. The proposed system that controlled overall and partial current takes advantage of the reduced power consumption under dynamic conditions of video sequences without offensive flicker and color distortion.
