Abstract
We propose an algorithm to dim the backlight of liquid crystal displays to reduce power consumption by finding a gray level that minimizes the change of luminance and combining conventional algorithm with the gray level by exploiting the characteristics of human visual perception. The algorithm reduced power consumption by 5 - 12% compared to the conventional algorithm that considers the maximum of the R, G and B channels.
