Plessey develops the world's first InGaN on Silicon red LED
UK-based GaN-On-Si MicroLED microdisplay developer Plessey Semiconductor announced that it has successfully developed the world’s first GaN on Silicon-based Red LED.
Red LEDs are typically based on AlInGaP materia, or are color-converted from blue LEDs. These red LEDs limit the efficiency and the ability to create ultra-fine pitch sub pixels. Plessey says that InGaN red LEDs will also offer lower manufacturing costs, scalability to larger 200 mm or 300 mm wafers and better hot/cold factor over incumbent AlInGaP-based Red.
