Multi-tone display device

An image display device comprising:

• a matrix display panel having a plurality of X direction signal lines arranged in a X direction and a plurality of Y direction signal lines arranged in a Y direction intersecting said plurality of X direction signal lines at intersecting points which correspond to a plurality of pixels, wherein an adjacent three of said pixels in the X direction represent red(R), green(G) and blue(B) respectively, and wherein said adjacent three of said pixels form one dot;
• a X direction driver which outputs driving voltages which makes said matrix display panel display multi-color of said R, G, and B representing a multi-tone;
• a Y direction driver scanning said plurality of Y direction signal lines in synchronism with said X direction driver,
• wherein said X direction driver has a first port and a second port for inputting a first multi-tone digital data which includes N-bits corresponding to each R, G, and B to display multi-color at a first dot of said matrix display panel and a second multi-tone digital data which includes N-bits corresponding to each R, G, and B to display a multi-color at a second dot of said matrix display panel in accordance with one clock pulse of a clock supplied from external of said X direction driver, and output terminals providing a first driving voltage corresponding to said first multi-tone digital data input via said first port to a part of said plurality of X direction signal lines corresponding to said first dot and providing a second driving voltage corresponding to said second multi-tone digital data input via said second port to a part of said plurality of X direction signal lines corresponding to said second dot adjacent to said first dot in the X direction.
