Low-power liquid crystal display television panel with reduced motion blur

Recently, there have been lots of demands for green products. One of solutions is to reduce the power consumption. Whereas the most approaches in liquid crystal displays (LCDs) are focused on reduction of the backlight power consumption with local dimming technologies, this paper proposes a new low power driving scheme for LCD TV panels operated at high frame rates of 120 Hz and 240 Hz. Dynamic power consumptions have been lowered by means of the frame rate reduction for still input image and fallback. As the maximum, the total dynamic power has been reduced by around 50% and 75% for 120 Hz and 240 Hz.
