Abstract:
A display system having a display matrix and comprising:first LED-light sources within said matrix each for generating light of a first nominal color and each having a neighboring second LED-light source that is for generating light of a second nominal color, said first LED-light sources having differing actual colors of light generated;memory associated with each of said first LED-light sources storing first information that is dependent on the actual color of light generated by the first LED-light source;a control system comprising drivers for energising said first and second LED-light sources and arranged so that when display light of said first nominal color is required from any given one of said first LED-light sources the display light of that source is modified by a chance of the light from its said neighboring second LED-light source, said change of light being dependent on said first information for the first LED-light source and on the amount of said required display light; andsaid change of light serving to reduce apparent color mismatches in said matrix caused by said differing actual colors.
