Liquid-Crystal-on-Silicon (LCoS) displays are crucial in augmented reality (AR) systems for their high resolution and small form. This manuscript explores the architecture, fabrication, and performance of a microLED zonal illuminator (ZI) to enhance image contrast and power savings in future LCoS-based optical engines. Prototype ZIs utilizing elastomer-stamp-transferred flip-chip microLEDs and driver microICs are presented.
