38‐3: Invited Paper: MicroLED Device Technology for Low‐Power Wearable Displays

This paper presents state of the art for materials and devices for use in low‐power wearable displays. We present efficiencies for InGaN‐R, G, B, and AllnGaP‐R materials, as well as the dependence of performance on current density and emitter size. We further show how display efficiency can benefit from the presented level of microLED performance and contrast various material systems and optimal driving conditions for different display sizes and applications.
