Abstract
Micro/Nano LED is one of hot topics for the next generation of display beyond OLED. GaN-based and Phosphide-based LEDs show terribly low emission efficiencies as the chip size gets smaller like <10. Therefore, current LED technology can’t provide efficient micro/nano LEDs suitable for VR/AR/MR display applications. We will introduce a revolutionary light emitting device, called Hybrid LED, in the presentation. Hybrid LED is composed of ZnO-based Oxide semiconductors and GaN-based Nitride semiconductors. Hybrid LED is a breakthrough for micro-LED display because its emission efficiency is constantly good enough for 5,000+ PPI display without affected by chip size unlike conventional Nitride-based and Phosphide-based LEDs. After brief discussion and review on Physical properties of Hybrid LEDs, commercial Hybrid LEDs in different colors (from blue to red) and chip sizes (a few to hundred microns) will be demonstrated to show how outstanding Hybrid LEDs are, compared with typical commercial GaN LEDs.
