色彩序列液晶显示器与其像素电路
摘要：
本发明提供一种色彩序列液晶显示器与其像素电路。该像素电路包括第一取样开关与第二取样开关、第一电压暂存器与第二电压暂存器、第输出开关一与第二输出开关、液晶电容，以及重置开关。第一电压暂存器耦接第一取样开关与第一输出开关，以于第一子帧期间暂存第一取样电压，并于第二子帧期间输出第一取样电压至液晶电容。第二电压暂存器耦接第二取样开关与第二输出开关，以于第二子帧期间暂存第二取样电压，并于第一子帧期间输出第二取样电压至液晶电容。重置开关耦接液晶电容，以于第一与第二子帧之间，传输重置电压至液晶电容。本发明可以增加像素电路运作的效率，并且延长像素的单色光源点亮的时间。
摘要（英）：

The invention provides a color sequence liquid crystal display device and a pixel circuit thereof. The pixel circuit comprises a first sampling switch, a second sampling switch, a first voltage register, a second voltage register, a first output switch, a second output switch, a liquid crystal capacitance and a replacement switch, wherein the first voltage register is coupled with the first sampling switch and the first output switch, first sampling voltage is temporarily stored during a first subframe period, and the first sampling voltage is output to the liquid crystal capacitance during asecond subframe period. The second voltage register is coupled with the second sampling switch and the second output switch, second sampling voltage is temporarily stored during the second subframe period, and the second sampling voltage is output to the liquid crystal capacitance during the first subframe period. The replacement switch is coupled with the liquid crystal capacitance, and replacement voltage is transmitted to the liquid crystal capacitance between a first subframe and a second subframe. The color sequence liquid crystal display device and the pixel circuit thereof can increasethe operation efficiency of the pixel circuit, and prolongs the time of lighting monochromatic light source of a pixel.
