Abstract:
1. An image display device having a group of pixels arranged in a matrix in a predetermined array and assigned to three primary colors, and having a signal line connected for each column of the group of pixels, wherein pixel data of three primary colors are successively supplied for each color to a corresponding signal line during a period excluding a blanking period of one horizontal scanning period constituted by a line display period for the color display of one pixel line, and wherein a select switch is connected to each of the signal lines, and a precharging control circuit is connected to the select switch, the precharging control circuit supplies permission pulses for the supply of data to signal lines when making them display one color among three primary colors in the line display period to the select switch of the corresponding signal line to turn the same on, turns on the select switch of the signal line corresponding to another color to be displayed later in the same line display period during a period of supply of permission pulses of the supply of data with a precharge pulse having a time duration shorter than the supply time of the pixel data of the other color, and precharges the signal line of the other color in advance to a predetermined potential.
