Multimodal Bioinspired Self‐Healing Composites Enabling Durable and High‐Efficiency Wearable Perovskite Light‐Emitting Diodes

ABSTRACT Wearable and flexible optoelectronic devices are rapidly advancing toward human‐interactive applications. However, their operational lifespan is often limited by mechanical damage, interface delamination, and environmental influences. Existing encapsulation methods provi...

High-Efficiency Direct AC LED Driver with Adaptive Constant-Power Architecture

This paper presents a high-efficiency direct-AC LED driver integrating a 14-stage voltage-segmented architecture, digitally coordinated stage selection, and adaptive current-reference regulation. The proposed driver provides finer matching between the rectified bus voltage and th...
