Abstract
A color display (100, 200) for displaying an image is described wherein the color display (100, 200) is adapted for displaying a number of basic color light channels (102a, 102b, 102c). The color display (100, 200) comprises a basic color combiner (112, 212) for combining the basic colors and at least one basic color light channel (102a, 102b, 102c) comprising at least two light sources (104) having different spectral characteristics. The color display (100, 200) furthermore comprises an adjuster (106, 206) for adjusting a basic color by adjusting a relative proportion of a luminous output from the at least two light sources (104) in the basic color light channel (102a, 102b, 102c). A corresponding adjuster/controller, a multi-display system and a corresponding method for setting and/or adjusting a display system also is described.
