VOLTAGE DIMMABLE LED DISPLAY PRODUCING MULTIPLE COLORS |
摘要 |
<p>Multi-color illumination for a single display 110 is achieved by utilizing a n array 104 of white light emitting diodes to produce illumination optically filtered by separate filters 107a-107d to produce the two or more desired output illumination colors at a desired luminance when the full rated voltag e is applied to the light emitting diodes 104. Since all of the light emitting diodes 104 have the same bandgap, voltage-controlled dimming produces unifor m luminance changes for all colors as the voltage is reduced. A single voltage - controlled dimming driver circuit design 200 and a single control voltage ma y therefore be utilized to achieve desired and uniform dimming characteristics independent of output illumination color.</p> |
