  • Publication number: 20090273556
    Abstract: To make a conventional area grayscale display technique applicable to a driving method that is designed to write data in a vertical blanking interval. A display panel with multiple pixels and a display controller that receives an input video signal and a sync signal and gets an image presented on the display panel are provided. If one horizontal scanning period and one vertical scanning period of the input video signal are represented by 1H and V-Total, respectively, the display controller is able to form one vertical scanning period V-Total of a first period in which one horizontal scanning period of the display panel is 1Ho, which is as long as 1H, and a second period in which one horizontal scanning period of the display panel is 1Hn, which is not as long as 1H.
