Abstract

A display comprising a plurality sub-pixel display elements respectively displaying different colors, arranged into a plurality of single-row pixels, wherein for adjacent pixels, each sub-pixel display element associated with the first pixel bears a minimal spatial distance to a respective sub-pixel display element associated with the second pixel that represents a color having a maximum color distance with respect to the color represented by such sub-pixel display element, as compared to the color distance between the color represented by the sub-pixel display element and other colors.

Claims

1. A display comprising a plurality of first, second, third, fourth, and fifth sub-pixel display elements, which are arranged in rows and controllable by row and column drivers to display first, second, third, and fourth, and fifth different colors, respectively, a first pixel of a displayed image being reproducible by sequential sub-pixel display elements in a single row of the display and a second pixel of a displayed image being reproducible by sequential sub-pixel display elements in a second single row of the display, said first and second rows being adjacent and co-planar, wherein for each sub-pixel display element associated with the first pixel, there is a minimal spatial distance between the sub- pixel display element and a respective element associated with the second pixel that represents a color having a maximum color distance with respect to the color represented by such sub-pixel display element compared to the color distance between the color represented by the sub-pixel display element and other colors.

2. A display according to claim 1, further comprising sixth sub-pixel display elements, which are controllable to display a sixth different color.

3. A display according to claim 1, wherein the display is a matrix display.

4. A display according to claim 1, wherein the different colors comprise red, blue, green, yellow and magenta.

5. The display of claim 4, further comprising sixth sub-pixel display elements, which are controllable to display a sixth different color, wherein said sixth color is cyan.

6. The display of claim 1, wherein a first sub-pixel display element representing a first color and a second sub-pixel display element representing a second color, said colors representing the greatest luminance, said first and second sub-pixel display elements being associated respectively with said first and second pixels are both arranged with respect to a third sub-pixel display element representing a third color such that the spatial distance of the first and second sub-pixel display elements is larger than the spatial distance of either said first or second sub-pixel display element to the third element.
