Abstract:
1. A method of displaying an image using a display pixel comprising at least one subpixel displaying one among four or more colors, the method comprising: adjusting a target phase of a target subpixel using a difference between an absolute luminance value of a color to be displayed by the target subpixel and an absolute luminance value of a color to be displayed by at least one subpixel adjacent to the target subpixel; and obtaining a relative luminance value of the target subpixel based on a relative luminance value of at least one image pixel using a target filter having the adjusted target phase as a center of the target filter, wherein a brightness of the color displayed by the target subpixel corresponds to the obtained relative luminance value of the target subpixel, and the adjusting of the target phase comprises
