Multi-field driving method for reducing LCD power consumption

We have developed a multi-field driving method for TFT-LCDs in which a displayed image was divided into at least three interlaced sub-field images where visible flicker did not occur as the image refresh rate was decreased. This method made it possible not only to reduce driving-power consumption in the case of still images to less than half, compared to that of conventional methods, but also to ensure that large-area flicker and line flicker were invisible to the human eye.
