| Abstract(in English) | Output luminance of an RGB-LED backlight for an LCD-TV was adaptively dimmed along with input video signal in fashions of 0D (uniform dimming), 1D (line dimming), and 2D (local dimming). It has been proven experimentally that the backlight power can be reduced to 83%, 71%, and 50%, respectively, for a typical sample movie having 8.0% post-gamma average picture level. Further simulation study revealed that the power consumption can be reduced to the value equal to that of the post-gamma APL. |
