Process of making monolithic rgb micro led display using down converting macromolecules

Abstract

A method of forming a multicolour light emitting array, the method comprising: providing a first light emitting device configured to emit light with a first primary peak wavelength and a second light emitting device configured to emit light with the first primary peak wavelength; forming a colour conversion region at least partially associated with the first light emitting device and the second light emitting device, wherein the colour conversion region is configured to absorb light with the first primary peak wavelength and emit light with a second primary peak wavelength longer than the first primary peak wavelength; and photo-bleaching a portion of the colour conversion region associated with the first light emitting device such that the colour conversion region associated with the first light emitting device is at least partially transparent to light with the first primary peak wavelength, thereby to enable light with the first primary peak wavelength to be emitted by a first pixel associated with the first light emitting device and light with the second primary peak wavelength to be emitted by a second pixel associated with the second light emitting device.
