Abstract: 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.

Abstract: A display device has displaying means for by having 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 region performing image display with pixel groups each forming one line in the vertical direction being scanned in the horizontal direction. Vertical-horizontal converting means is provided for converting an image data stream supplied presupposing n pixels in a horizontal direction and m horizontal lines in a vertical scanning direction into an image data stream for 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 displaying means by display controlling circuit means.
