Abstract:
1. A display device comprising: a pixel array having a plurality of pixels arranged in rows extending in a first direction and columns extending in a second direction intersecting said first direction, each of said plurality of pixels being provided with a switching element; a plurality of first signal lines extending in said first direction and arranged in said second direction, each of said plurality of first signal lines supplying a first signal to said switching elements in ones of said plurality of pixels belonging to a corresponding one of said rows; a plurality of second signal lines extending in said second direction and arranged in said first direction, each of said plurality of second signal lines for supplying a second signal to at least one of said switching elements in ones of said plurality of pixels belonging to a corresponding one of said columns and supplied with said first signal such that said at least one of said switching elements determines a display state associated therewith; a first drive circuit for supplying said first signal to each of said plurality of first signal lines; a second drive circuit for supplying said second signal to each of said plurality of second signal lines; and a display control circuit for (i) generating a timing signal for determining a timing for said first drive circuit to output said first signal, and (ii) generating video data used for generation of said second signal by said second drive circuit, based upon video information per frame period, wherein said plurality of first signal lines are divided into a plurality of groups each comprising plural adjacent ones of said plurality of first signal lines, said frame period includes a first time interval and a second time interval, said first drive circuit supplies said first signal to said plurality of groups successively during each of said first time interval and said second time interval, all of said first signal lines of each of said plurality of groups being supplied with said first signal at one time, said second drive circuit generates said second voltage corresponding to said video data and supplies said second voltage to ones of said plurality of pixels associated with one of said plurality of groups of first signal lines supplied with said first signal during said first time interval, and said second drive circuit generates said second voltage and supplies said second voltage to ones of said plurality of pixels associated with one of said plurality of groups of first signal lines supplied with said first signal during said second time interval such that said ones of said plurality of pixels associated with said one of said plurality of groups of first signal lines supplied with said first signal produce luminance lower than that produced during said first time interval.
