Abstract
A dot matrix display device includes a pixel redraw control unit and a decoder unit. The pixel redraw control unit generates a gate selection signal identifying an address in one direction, a source selection signal identifying an address in another direction intersecting the one direction, and image data which correspond to a pixel electrode part based on a serial signal including an address signal identifying an address of the pixel electrode part and an image signal supplied to the pixel electrode part. The decoder unit supplies a gate signal which activates a gate signal line corresponding to the pixel electrode part based on the gate selection signal, generates a source signal which activates a source signal line corresponding to the pixel electrode part based on the source selection signal, and supplies the image data to the pixel electrode part corresponding to the activated source signal line.
