Abstract :
Local dimming techniques cause clipping artifacts in liquid crystal displays. To overcome the problems associated with the artifacts, the backlight luminance should be adjusted, but this process increases power consumption. In this paper we propose a novel backlight luminance compensation algorithm to reduce clipping artifacts by minimizing the increment of backlight luminance.
