Featuring high resolution, high contrast and high brightness, Micro LED is regarded as the “ultimate display technology.” However, due to production difficulties, the technology has not yet entered the commercial market despite that the first prototypes were revealed back in 2012. Recently, driven by leading brands including Apple and Samsung, we have seen more and more Micro LED displays presented. But industry experts forecasted that it would take at least three years for the technology to truly enter the consumer market. Mass transfer is a notorious challenge...

German semiconductor manufacturer, Azzurro LED Technologies, announced during a talk at ICNS-10 that the company’s technology has reached the capability of achieving “1 bin” GaN-on-Si LED wafers. While showing production values of less than 3 nm wavelength uniformity, the 1.0 nm result came straight from development. The record 1.0 nm result demonstrates the capability to achieving “1 bin” GaN-on-Si LED wafers.
