Method and apparatus for adjusting a mixed light produced by first and second light sources of first and second colors

In one exemplary method, a mixed light is produced using first and second light sources of first and second colors. In one embodiment, the first and second light source are a white light source and a colored (e.g., red) light source. A determination is then made as to whether feedback tristimulus va...

Zusammenfassung:In one exemplary method, a mixed light is produced using first and second light sources of first and second colors. In one embodiment, the first and second light source are a white light source and a colored (e.g., red) light source. A determination is then made as to whether feedback tristimulus values, representative of the mixed light, are within a range of reference tristimulus values. If one or more of the feedback tristimulus values is out of range, a luminance ratio between the first and second light source is adjusted. In one embodiment, the mixed light is used as a backlight for a liquid crystal display.
