摘要

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 the new low power driving scheme for LCD TV panels operated at high frame rates of 120Hz and 240Hz. Dynamic and static power consumptions have been lowered by means of the frame rate reduction for still input image and fallback and the charge sharing method applied at the vertical blank period. As the maximum, the total power can be reduced to around 50% and 75% for 120Hz and 240Hz.
