Abstract: Multi-color illumination for a single display is achieved by utilizing an array of white light emitting diodes to produce illumination optically filtered by separate filters to produce the two or more desired output illumination colors at a desired luminance when the full rated voltage is applied to the light emitting diodes. Since all of the light emitting diodes have the same bandgap, voltage-controlled dimming produces uniform luminance changes for all colors as the voltage is reduced. A single voltage-controlled dimming driver circuit design and a single control voltage may therefore be utilized to achieve desired and uniform dimming characteristics independent of output illumination color.
