  • Backlight for a color LCD using wavelength-converted light emitting devices
    Publication number: 20040061810
    Abstract: A backlight for an LCD uses as a light source at least one red light source, at lest one green light source, at least one blue light source, wherein one of the sources comprises a light emitting diode capable of emitting light at a first wavelength and a wavelength-converting material capable of absorbing light of the first wavelength and emitting light of a second wavelenght. In some embodiments, the wavelength-converting material is a strontium thiogallate phosphor or a nitridosilicate phosphor. In some embodiments, the first wavelength is about the same as light emitted by the blue light source, or is barely visible to the human eye.
