Porous-GaN material platform developer Porotech is demonstrating its latest microLED display prototypes at Touch Taiwan 2022. The company is showing 1920x1080 monochrome microidsplays, that achieve over 2 million nits of brightness. All displays use native indium gallium nitride (InGaN)-based LEDs.
The company says it is the first to demonstrate all three-color light emitting elements made from a single material and toolchain. This include Porotech's native red InGaN display at 614-625nm wavelength.
Porotech says it is developing full-color InGaN-based monolithic microLED displays and the company expects to be making an exciting announcement "very soon".
In 2021 Porotech announced it has created the world's first microLED microdisplay based on a native red InGaN LED. The microdisplay was a 0.55" diagonal panel with a resolution of 960x540 Porotech says that its native InGaN red LEDs will offer higher efficiency than currently-used AlInGaP red LEDs. Developing an RGB microdisplay all from InGaN chips will also offer easier driving and process design.
Earlier in 2021, Porotech announced a partnership with JBD for the supply of porous gallium nitride (GaN) epiwafers. In February 2022 Porotech raised $20 million in its Series A financing round.
