Abstract:
A display device comprising:a pixel section having pixels arrayed in lines; a vertical drive system for sequentially setting each pixel of the pixel section by lines to active status; a control circuit for setting pixels of a specified area on the left and right or upper and lower of the pixel section to active status by applying a control signal; and a horizontal drive system for writing a specified luminance level signal for all pixels of an area set in active status by the control circuit, and also writing for pixels of all other areas, display signals in each line sequentially set to active status by the vertical drive system, wherein: said control circuit comprises a plurality of two-input gate circuits formed for each line to set each pixel to active status according to output of said gates, each of a specified number of gate circuits corresponding to said specified areas from among said plurality of gate circuits has two inputs for said control signal and vertical scanning signal to scan each pixel in the pixel section in the line direction, and each of said plurality of gate circuits corresponding to areas other than said specified areas has two inputs for a vertical scanning signal for scanning each pixel of said pixel section in the line direction and a signal of a fixed level to pass the vertical scanning signal unchanged.
