Abstract

Blur-mask approach (BMA) was developed to simulate the light distribution of locally controlled LED backlight, providing much lower computational complexity which is less than 1% of that of conventional convolution approach and being successfully demonstrated on a 37” high dynamic range (HDR) LCD-TV with real-time modification to perform high quality image (Less image distortion) and high contrast ratio ($\sim {\hbox{20{,}000}}$:1 with test image-Lily).
