  • Patent number: 9117393
    Abstract: It is intended to provide a field sequential color display device capable of reducing the problem of saccadic color breakup. The color display device represents color images by depicting data of respective color images with a monochromatic display element in synchronism with sequential on-off switching to three color light sources of red, green and blue. Each display frame, which is the minimum cycle of sequential on-off switching of red, green and blue light sources to display any given color image, includes a red color field for displaying data of a red color image, a green color field for displaying data of a green color image and a blue color field for displaying data of a blue color image. In each green color field, at least the red light source or the blue light source is turned on and off in addition to the green light source.
