Abstract
Provided are a color display driving principle obtained while taking into account a difference in eye sensitivity to the flickering of differently colored lights, a TFT liquid crystal display module structure that is adequate for this method, and a double-panel projection type display device. The count of the G (green) color data that can be written is increased compared with the count for the other primary colors, or the display period for green can be extended. The repetitive unit is set to R, G, B and G, so that a satisfactory refresh rate can be set for the important color G. Therefore, the overall refresh frequency and the power consumed by the display device can be reduced without deterioration of the display quality, and requests for the time response speeds by the display device can be reduced.
