In typical use, a liquid crystal display (LCD) with high resolution, brightness and color saturation can consume over half the total system power in a modern mobile device. This paper examines LCD optical transmittance and system electrical design to extend battery run time. By applying a solid understanding of critical optical parameters and complementary system design, a low power “Green” display can be achieved. The LCD in the Pixel Chromebook [1], will be used as a baseline for discussion.
