Image display device, electronic apparatus, and pixel location determining method

An image display device, comprising:

• a plurality of display pixels that display an image, each display pixel including at least four sub-pixels that provide different colors, the at least four sub-pixels defining an average level of luminance;
• the at least four sub-pixels including two edge sub-pixels disposed at opposite lateral edges of the display pixel, the two edge sub-pixels having a level of luminance smaller than the average level of luminance of the at least four sub-pixels, the luminance and the luminance added value being defined in a luminance and opponent-color space.

A method for determining locations of sub-pixels of a display device that includes multiple display pixels, each display pixel including four of the sub-pixels, that provide different colors, the method comprising:

• determining locations of two edge sub-pixels of the four sub-pixels at opposite lateral edges of the display pixel, the two edge sub-pixels having a smaller luminance level;
• and
• determining locations of two central sub-pixels disposed between the two edge sub-pixels, such that 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 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.

A method of manufacturing a display that includes multiple display pixels, each of the display pixels including four sub-pixels, the method comprising:

• displaying two edge sub-pixels at opposite lateral edges of each display pixel;
• and
• displaying two interior sub-pixels of the four sub-pixels 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.
