About this technology

Overview

NASA Langley Research Center has developed a process methodology for making red, green and blue LED device structures on the same substrate (wafer), which is not possible today using current techniques. Such devices are manufactured individually because of different crystal structures. This innovation is enabled by the prior innovations by NASA Langley Research Center.
