MicroLED Display on 300mm CMOS Platform - Crosstalk and Optical Outcoupling

Abstract

We have implemented microLED integration into a 300mm CMOS platform with 9150ppi and brightness > 1Mnits. Here we show the impact of light outcoupling optimization on optical crosstalk and efficiency extraction. By implementing wafer level optics we achieve a crosstalk reduction of more than 20dB between neighboring pixels with >20% of the light within the APEX angle of +/-20deg relevant for waveguide optics.
