Stacked-RGB based microLED microdisplays
US-based Sundiode develops microLED microdisplays based on its unique stacked-RGB pixel structure.
In 2021, in collaboration with KOPTI and Jasper Display, Sundiode unveiled a microdisplay prototype that features 200 PPI and 100um pixels. The display is an array of stacked-RGB micro-LED pixels on a single chip bonded directly onto a Si CMOS backplane. In 2023 the company successfully grew a monolithic all-InGaN stacked-RGB LED structure.
