Patent ID: 7804640

Claim:
A monolithic up-converting resonant cavity light emitting diode RGB pixel device comprising: an array of resonant cavity light emitting diodes producing an output light; an array of up-converters coupled with the array of resonant cavity light emitting diodes, wherein the output light from the array of resonant cavity light emitting diodes induces optical excitation in the array of up-converters, each up-converter comprising: an optical cavity coupled with one of the array of resonant cavity light emitting diodes; and an up-converting material deposited on the optical cavity, wherein cavity tuning is accomplished by a thickness of the up-converting material; and a power source for applying an electrical energy to the array of resonant cavity light emitting diodes for generating an output to excite the up-converting material to convert near-infrared light from the resonant cavity light emitting diodes to a light in a visible range.
