Evaluation of LCD local‐dimming‐backlight system

Abstract

Abstract— Local‐dimming backlight techniques can significantly improve the static contrast and power consumption of LCD panels. Several local‐dimming backlight systems have been previously reported. However, there is currently no comprehensive description regarding the evaluation of such systems. This paper proposes some methods for evaluating the power consumption, brightness, and contrast performance of local‐dimming backlight systems and discusses the general artifacts affecting the image quality for these systems.
