MULTI-COLORED LED ARRAY ON A SINGLE SUBSTRATE

摘要

A multi-colored display includes a semiconductor substrate layer, a first light emitting diode (“LED”) integrated onto the semiconductor substrate layer to natively emit pump light having a first color, a second LED integrated onto the semiconductor substrate layer to natively emit the pump light having the first color, and a first wavelength conversion layer disposed over an emission aperture of the second LED to convert the pump light natively emitted from the second LED to first output light having a second color different from the first color of the pump light. The first wavelength conversion layer includes a first matrix of quantum dots. The first and second LEDs are integrated into a single semiconductor die.
