Abstract

A display and methods of driving the display, where the display includes a plurality of pixels, where some colors are present in every pixel, and some colors are only present in less than all of the pixels.

Claims

1. A display comprising a plurality of pixels, each pixel including a plurality of sub-pixels, wherein the number of non-white sub-pixels in each pixel is different than the number of non-white colors of sub-pixels in the display, wherein the number of different non-white colors of sub-pixels in the display is at least five.

2. The display of claim 1, wherein the non-white colors of sub-pixels in the display are red, green, blue, yellow, and cyan.

3. The display of claim 2, wherein a size of the blue sub-pixel is larger than a size of the yellow sub-pixel.

4. The display of claim 1, wherein each pixel comprises four sub-pixels.

5. The display of claim 4, wherein the four sub-pixels include a first sub-pixel and a second sub-pixel, the first and second sub-pixels having different sizes.

6. The display of claim 5, wherein the first and second sub-pixels are blue and yellow, and wherein a size of the blue sub-pixel is larger than a size of the yellow sub-pixel.
