Display pixels with alternating colors

A color display, comprising:

• a substrate;
• a plurality of pixels located on the substrate, each pixel including only three light-emitting sub-pixels that each emit light of a different non-white color, the plurality of pixels including a first sub-set of first pixels and a second sub-set of second pixels, the second pixels having locations alternating with the first pixels, each of the first and second pixels including at least one first sub-pixel emitting light of a common first color, and the second pixels including at least one different sub-pixel emitting light of a different color that is not emitted by any sub-pixel of the first pixels;
• and wherein
• the light emitted by the sub-pixels of the first pixels defines a full-color gamut, and the light emitted by the sub-pixels of the second pixels defines less than a full-color gamut;
• the plurality of pixels includes a third sub-set of third pixels having locations alternating with the first and second pixels;
• the third pixels include at least one first sub-pixel emitting light of the common first color;
• and
• the third pixel includes a second different sub-pixel that emits light of a second different color that is not emitted by any of the sub-pixels of either the first or second pixels.

• and
• a display signal having a luminance signal and a color signal specifying the light emitted by each pixel and wherein the luminance signal emitted from the first or the second pixels is not resolvable by a user viewing the color display and the color signal emitted from each pair of pixels is not resolvable by a user viewing the color display within a desired viewing distance range.
