The light-emitting display includes a processor and a display having a plurality of light-emitting elements (LEEs). The LEEs comprise at least three basic primary colors, and at least one additional primary color. For at least part of the display system, one of the at least three basic primary colors is replaced by said at least one additional primary color, or said at least one additional primary color is added to and/or in between said at least three basic primary colors. And the processor is configured to perform at least one mathematical operation for adjusting color balance of said LEEs. ## Claims ### Claim 1 A light-emitting display system comprising: a processor;
