Column electrode driving circuit for use with image display device and image display device incorporating the same
A column electrode driving circuit for an image display device for selecting, from among a plurality of reference voltage levels, reference voltage levels respectively corresponding to gray scale levels in input data, and outputting the respective selected voltage levels to at least one data line. The input data includes data of a first color, a second color, and a third color. The reference voltage levels are independently selected corresponding to the gray scale levels in the input data of the first, second, and third colors. Among the reference voltage levels independently selected corresponding to a given gray scale level in the input data of the first, second, and third colors, the reference voltage level selected corresponding to at least one color is different from the reference voltage level or levels selected corresponding to the other color or colors, the given gray scale level being within a predetermined range. The reference voltage level selected corresponding to the given gray scale level in the input data of the at least one color is equal to a reference voltage level selected corresponding to another gray scale level in the input data of the other color or colors.
