Abstract
A full-color LED micro-display having a plurality of pixels is disclosed. Each pixel includes a first LED comprising a blue/green dual wavelength LED structure for emitting blue light; a second LED comprising the blue/green dual wavelength LED structure for emitting green light; and a third LED comprising a monochrome red LED structure for emitting red light. The blue/green dual wavelength LED structure includes a dual wavelength MQWs active region of a first material with two emission peaks. The dual wavelength MQWs active region includes a first quantum well stack, a second quantum well stack, and a third quantum well stack. The first and the third quantum well stack are configured for generating the blue light, and the second quantum well stack is configured for generating the green light. The monochrome red LED structure further comprises a red emitting MQWs active region of a second material with a second emission peak.
