A real-time liquid crystal signal compensation method for high dynamic range LCD

Abstract

Blur-mask approach was developed to simulate the backlight distribution of locally-controlled dimming LED backlight with lower computational complexity which is less than 1% of conventional convolution method. The If blur-mask approach was demonstrated to perform high image, quality and high contrast ratio (similar to 20,000 : 1) on a 37" LCD-TV. Compared with convolution, blur-mask approach has much lower computational complexity and succesfully demonstrated for real-time application.
