Patent ID: 7889216

Claim:
An image display device, comprising: a plurality of display pixels that display an image, each display pixel including four sub-pixels that provide different colors; the four sub-pixels including two edge sub-pixels disposed at opposite lateral edges of the display pixel and two interior sub-pixels disposed laterally between the two edge sub-pixels, such that the two edge sub-pixels have a smaller level of luminance, and an absolute value of a difference between a luminance added value, which is a value obtained by adding luminance levels of one of the two edge sub-pixels and an adjacent pixel, and a luminance added value, which is a value obtained by adding luminance levels of the other edge sub-pixel and an adjacent pixel, is reduced as compared to the absolute value of other possible configurations of the four sub-pixels, the luminance and the luminance added value being defined in a luminance and opponent-color space.
