Patent ID: 7967653

Claim:
A method of fabricating a full color display comprising the steps of: providing a substrate; defining a plurality of regularly positioned pixels on the substrate, each pixel including a red, a green, and a blue light emitting diode; selecting a rare earth material for each of the red, the green, and the blue light emitting diodes, the rare earth materials having at least one radiative transition producing a radiation wavelength of approximately 640 nm for the red light emitting diode, 540 nm for the green light emitting diode, and 460 nm for the blue light emitting diode, respectively; positioning a first mirror on the substrate for each light emitting diode in each pixel; epitaxially growing a first cladding layer of intrinsic single crystal semiconductor material on each of the first mirrors; epitaxially growing a light emitting area including at least one thin single crystal layer of the selected rare earth material on the first cladding layer of each light emitting diode of each pixel; epitaxially growing a second cladding layer of intrinsic single crystal semiconductor material on the light emitting area of each light emitting diode of each pixel; and positioning a second mirror on the second cladding layer of each light emitting diode of each pixel.
