ABSTRACT:
One frame of a video signal is separated to a plurality of display frames. To display a color specified by the video signal by mixing display colors of a plurality of display frames, the video signal is converted to data indicative of a voltage to be applied to each pixel over the display frames by using a conversion table. A voltage corresponding to the converted data is applied to a birifringence control type liquid crystal display device to drive the liquid crystal display device multiple times in one frame period of the video signal. When the response speed of the liquid crystal is fast, a color obtained by mixing the display colors of a plurality of display frames is recognized by an observer. When the response speed of the liquid crystal is slow, a color corresponding to an average value of the voltages applied to a plurality of display frames is recognized by the observer. When the liquid crystal has an intermediate response speed, a color obtained by visually mixing a series of display colors displayed during the transition of the alignment state of the liquid crystal is recognized by the observer.
