Researchers from Korea's KAIST, Inha University, QSI and Raontech have jointly developed a high-density high-efficiency red microLED microdisplay, achieving a pixel density of 1700 PPI.
The researchers used Aluminum Indium Phosphide/Gallium Indium Phosphide (AlInP/GaInP) quantum-well microLEDs, and applied a monolithic 3D integration process to stack the microLED array directly on top of the backplane.
