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.
