3,000 ppi full-color “Silicon Display” has successfully been demonstrated based on monolithic micro-LED and Cd-free quantum dot (QD) color conversion technology. “Light-shielding wall (LSW)” is the key to prevent optical cross-talk. The demonstrator with 8.4um square pixel including RGB sub-pixels has shown wide color gamut exceeding 111% of sRGB.
