Patent ID: 7471706

Claim:
An integrated light emitting device, comprising: a substrate; at least one semiconductor light emitting device comprising an active region formed in or on said substrate, and upconverting material disposed in or on said substrate outside said active region and outside any laser cavity, wherein said upconverting material is disposed in a path of light processed by said device or emitted by said active region, said upconverting material absorbing light emitted by said active region and spontaneously emitting upconverted light in response; wherein said at least one light emitting semiconductor device comprises a first, second and third semiconductor light emitting device formed in or on said substrate and said integrated light emitting device comprises at least one pixel operable for emitting red light, green light and blue light, said pixel comprising red light emitting upconverting material optically coupled to said first semiconductor light emitting device, green light emitting upconverting material optically coupled to said second semiconductor light emitting device, and blue light emitting upconverting material optically coupled to said third semiconductor light emitting device.
