The first signal is set to one of a first polarity and a second polarity, and the second signal is set to one of the first polarity and second polarity, wherein the first signal and the second signal form a first sequence. A pixel of the given color in a second pixel group that is adjacent the first pixel group is driven with a second sequence of signals that is the same as the first sequence.

Abstract: In a displaying method for use in an image display, an original gray scale is divided into a higher gray scale and a lower gray scale. Further, the color subpixels are divided into two groups corresponding to the higher and lower gray scales, respectively. The gray scale to be expressed by each subpixel is calibrated by weighing the original higher or lower gray scale for the pixel and the adjacent pixels and summing up the results. The color shift problem due to different visual angles can therefore be solved.
