ACC: Alternating Complementary Colors for Display Energy Reduction

Displays are by far the most consuming devices in the video chain. In this paper, a novel method to reduce their consumption is disclosed that leverages the human vision’s properties and replaces each image pixel color by two other complementary colors, whose average power is lower than the original one. When applied just before a display panel, such a replacement allows to reproduce identical visual stimuli and does not impact the quality of experience (QoE). Two versions of the method are proposed depending on how the complementary colors temporally or spatially alternate, that achieve an average power reduction gain of up to 3.8% (max. 11%).
