Abstract:
Described herein are ILED displays including redundancy in micro-light emitting diode (micro-LED) dies and methods of manufacturing the ILED displays. A micro-LED die emits light of a particular wavelength. The redundancy is added during manufacturing if defective micro-LED dies are identified. Additional micro-LED dies are included in inoperable sub-pixel assemblies to repair the inoperable sub-pixel assemblies that are identified to include defective micro-LED dies. An ILED display therefore includes at least one repaired sub-pixel assembly that includes two defective micro-LED dies and an operable micro-LED die that are coupled to separate branches of a current path from a current source.
