Abstract

Based on the optimised high‐voltage network design and the resistance matching technique, a wafer‐level light emitting diode (WL‐LED) with a light output power of 157 W has been successfully demonstrated for the first time. The external quantum efficiency of the fabricated WL‐LED was measured to be 24% at a driving current of 4 A. [ABSTRACT FROM AUTHOR]
