Abstract

Abstract : Microdisplays based on an array of micro‐sized GaN‐based light emitting diodes (μLEDs) are very promising for high brightness applications. In this paper we investigate electro‐optical properties of μLEDs arrays. A particular focus is made on size‐reduction and light emission inhomogeneities. This work led us to process improvements, increasing maximum efficiency by 40%, reducing droop effect and enhancing brightness up to 10 7 cd/m².
