Abstract

Viewing angle characteristics of a liquid crystal display (LCD) (112) are improved by reducing the number of subpixels in an image with mid-tone luminance values. In a preferred embodiment, a first table of entries associating subpixel intensity values and subpixel luminance values for a LCD (112) in at least one viewing angle direction is provided. A second table associates the target intensity values with values above and below the target. The adjacent subpixel intensity values are modified according to the second table, thereby reducing the number of subpixels with mid-tone luminance values.
