Abstract
An image-signal driving circuit inputs serial sequences of image data DA, DB, and DC for key or primary colors, converts the image data into parallel data for displaying one line on a display, and supplies the parallel data to the display. The image-signal driving circuit comprises a register that inputs sequences of image data for the number of primary colors, stores the image data in order, and outputs the image data as parallel data; a latch that latches the sequences of image data for the number of primary colors output from the register as the parallel data; and a selector that selects one sequence of image data from the sequences of image data for the number of primary colors latched by the latch in predetermined order, and supplies the image data to the display.
