Patent ID: 7755594

Claim:
A field-sequential type display device for performing a display by synchronizing successive switching of lights of only three colors, which consist of red, green and blue, to be incident on a display element with light control in said display element based on display data of each color corresponding to an image to be displayed, comprising: a detecting unit for detecting a grayscale level of maximum brightness of the display data for each color, the grayscale level of the maximum brightness being variable for each of three sub-frames corresponding to the three colors throughout performing the display; a light control variable adjusting unit for adjusting, independently for each color, an intensity of light incident on said display element and a light control variable in said display element, based on the respective grayscale level of each color detected in said detecting unit; and a transmittance adjusting unit for adjusting a transmittance of said display element, wherein said transmittance adjusting unit adjusts a transmittance of maximum grayscale level among grayscale levels in a sub-frame corresponding to a color detected by said detecting unit, to be larger than said transmittance of maximum grayscale level at the time when said intensity of light incident on said display element becomes maximum, said light control variable adjusting unit adjusts said intensity of light incident on said display element and said light control variable in said display element for each light of a color among said three colors, in accordance with said transmittance adjusted by said transmittance adjusting unit, and the display is performed with said adjusted light control variable.
