Abstract

A light emitting device and method of manufacture are described. In an embodiment, the light emitting device includes a micro LED device bonded to a bottom electrode, a top electrode in electrical contact with the micro LED device, and a wavelength conversion layer around the micro LED device. The wavelength conversion layer includes phosphor particles. Exemplary phosphor particles include quantum dots that exhibit luminescence due to their size, or particles that exhibit luminescence due to their composition.
