Plessey - Native Blue and Native Green Emission microLEDs from the same Wafer

Plessey, an embedded technologies developer at the forefront of microLED technology for augmented and mixed reality (AR/MR) display applications has extended the capability of their proprietary GaN-on-Silicon process to enable Native Blue and Native Green emission from the same wafer. The potential of microLEDs is well known but several challenges remain before ramping up to large scale consumer applications. To form RGB microLED displays, typical approaches are to use a pick and place process to transfer discrete R, G and B pixels or to use Native Blue LEDs as the light source for subsequent colour conversion, to Red and Green.
