The Performance Degradation of Red, Green, and Blue Micro-LEDs Under High-Temperature Electrical Stress

The Performance Degradation of Red, Green, and Blue Micro-LEDs Under High-Temperature Electrical Stress

In this work, the degradation in luminous characteristics of red, green, and blue (RGB) micro-LEDs (10 µm × 10 µm) under electrical stress at 360 K has been investigated. After 280 h of aging, the AlGaInP-based red micro-LEDs exhibit a 31.7% reduction in maximum external quantum efficiency, which is...
