摘要： A display device has a line scan driving circuit disposed in a horizontal direction of a display region and a pixel driving circuit (dot scan driving circuit) disposed in a vertical direction of the display for performing image display with pixel groups each forming one line in the vertical direction being scanned in the horizontal direction. Vertical-horizontal converting circuitry is provided for converting an image data stream supplied with n pixels in a horizontal direction and m horizontal lines in a vertical scanning direction into an image data stream with m pixels in a vertical direction and n vertical lines in a horizontal scanning direction, and the vertical-horizontal converted data is supplied to the display device by a display controlling circuit. That is, image data is supplied to the displaying device as a vertical-horizontal converted data stream and display operation is executed by vertical pixel rows being scanned in the horizontal direction, as a result of which the relatively small line scan driving circuit is disposed above or below the display region instead of the relatively large dot scan driving circuit and thus the area required for circuit mounting above/below the display region is reduced and the size of the display device in the vertical direction can be effectively reduced.
