Patent ID: 7907155

Claim:
A display device comprising: a plurality of video signal lines configured to transmit a video signal based on an image to be displayed; a plurality of scanning signal lines intersecting with the plurality of video signal lines; a plurality of pixel formation portions arranged in a matrix respectively corresponding to intersections of the plurality of video signal lines and the plurality of scanning signal lines; and a display control circuit configured to outputs the video signal and a scanning-signal-line drive timing signal for driving the plurality of scanning signal lines; wherein a frame period, which is a period for displaying an image of one screen, is divided into one or more dark display periods when a relatively low luminance image is displayed and one or more bright display periods when a relatively high luminance image is displayed, and the image of one screen is displayed using the one or more dark display periods and the one or more bright display periods by displaying with luminances determined based on a gradation of the image of one screen during each of the one or more dark display periods and the one or more bright display periods; wherein one dark display period is set to be a period shorter than one bright display period; wherein the display control circuit is configured to output the scanning-signal-line drive timing signal such that each two or more reference number of scanning signal lines of the plurality of scanning signal lines is driven at the same time during the dark display period; and wherein the display control circuit is configured to output the video signal such that, during a period when the two or more reference number of scanning signal lines are driven at the same time, a luminance of a combined pixel formation portion group, which is a plurality of pixel formation portions arranged corresponding to intersections of the two or more reference number of scanning signal lines and each of the video signal lines, becomes an average value of luminances to be displayed during the dark display period at a plurality ofpixel formation portions included in the combined pixel formation portion group and to be determined based on the gradation of the image of one screen.
