Blind: Power saving color transform method for OLED displays

Abstract

With the superior color gamut and contrast, the OLED display technology has been widely used in mobile devices. Although, with self-emitting diodes, the OLED display can be potentially more power-efficient than the competing LCD display technology, it can often suffer from high energy consumption for displaying bright images. OLED has different energy consumptions for red, green, and blue color components, with diverse energy behaviors for different colors. To reduce the power consumption, this paper proposes Blind, a color management scheme, which exploits the human color perception inaccuracy. Blind changes a color space to another imperceptibly different color space with higher energy efficiency, achieving up-to 5.9% power reduction for smart phone applications.
