Plessey developed a 2.5-micron pitch MicroLED microdisplay

UK-based GaN-On-Si MicroLED microdisplay developer Plessey Semiconductor announced that it has developed a 2.5-micron pitch display, improving on its previous 8-micron pitch display it has demonstrated in May 2019 at SID DisplayWeek.

The new display sports a 2000x2000 resolution and is a monochrome blue display. Plessey says that in early 2020 (during CES 2020, in fact) it will demonstrate a full RGB display on one wafer.

In 2019 Plessey also announced that it developed green micro-LED devices that emit green light natively. On the other hand the company is also working with Nanoco to develop quantum dots based color conversion solutions, so it is not clear how Plessey actually aims to produce full-color microdisplays.
