Micro light-emitting diode array with improved light extraction

摘要

A light emitting diode (LED) (10) comprises a first spreader layer (20), an array of light emitting elements (12) disposed on the first spreader layer (20), and a second spreader layer (24) disposed over the array of emitting elements (12). The first spreader layer (20) is electrically isolated from the second spreader layer (24). The LED (10) also comprises first and second contacts (22, 26) on the first and second spreader layers (20, 24) respectively. A bias applied across the contacts (22, 26) causes the array of emitting elements (12) to emit light.
