Abstract:
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, wherein said intersecting points correspond to a plurality of pixels, wherein three of said pixels, arranged adjacently in the X direction, represent red(R), green(G) and blue(B) respectively, and wherein said three of said pixels R, G and B form one dot;a X direction driver which outputs driving voltages making said matrix display panel display multi-color of said R, G, and B representing a multi-tone;a Y direction driver which scans said plurality of Y direction signal lines in synchronism with driving by said X direction driver,wherein said X direction driver has a first port and a second port receiving first multi-tone digital data and second multi-tone digital data respectively in accordance with one clock pulse of a clock supplied from external of said X direction driver,wherein said first multi-tone digital data includes N-bits corresponding to each R, G, and B to display a multi-color at a first dot of said matrix display panel,wherein said second multi-tone digital data includes N-bits corresponding to each R, G, and B to display a multi-color at a second dot of said matrix display panel, andwherein said X direction driver provides 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 said X direction driver provides 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.
