Dr. Michael Bass issued patent "High Resolution, Full Color, High Brightness Fully Integrated Light Emitting Devices and Displays"
The United States Patent Office has issued Dr. Michael Bass the patent "High Resolution, Full Color, High Brightness Fully Integrated Light Emitting Devices and Displays", Patent Number 7,471,706.
Abstract:A light emitting device includes a substrate, at least one semiconductor light emitting device formed in or on the substrate, and upconverting material disposed in or on the substrate. The upconverting material is disposed in a path of light processed or emitted by the semiconductor device. The upconverting material absorbs light emitted by the semiconductor device and emits upconverted light in response. Integrated pixelated displays include a plurality of pixels formed on a surface of the substrate, with each pixel including up-conversion material based red light source, a blue light source a green light source, and a structure for selectively controlling emission from the red, blue and green lights sources for each of the pixels.
