    • An additional capacitor (“sharing capacitor”) is provided for each pixel of a liquid crystal display to store the previous voltage on the pixel electrode (i.e. the voltage obtained in the previous frame). At an opportune time after the pixel electrode has begun to charge for the current frame, the sharing capacitor's electrode is coupled to the pixel electrode to combine the pixel electrode's voltage with the sharing capacitor's voltage. As a result, the pixel electrode's voltage is changed to take into account the previous voltage so as to increase the liquid crystal's response speed. More particularly, the sharing capacitor's voltage changes the pixel voltage to provide a greater voltage overshoot or undershoot when the pixel color is changed a lot, so as to increase the liquid crystal response time. Therefore, greater response speed is provided at low power.
    • 为液晶显示器的每个像素提供一个附加的电容器(“共享电容器”)来存储像素电极上的先前电压(即在前一帧中获得的电压)。 在像素电极已经开始为当前帧充电之后的适当时刻,共享电容器的电极耦合到像素电极,以将像素电极的电压与共享电容器的电压组合。 结果,改变像素电极的电压以考虑到先前的电压,从而提高液晶的响应速度。 更具体地,当像素颜色变化很大时,共享电容器的电压改变像素电压以提供更大的电压过冲或下冲,从而增加液晶响应时间。 因此,在低功率下提供更高的响应速度。
