Porous-GaN material platform developer Porotech has demonstrated a full-color microLED microdisplay, made from the company's GaN LEDs. The company says that this is the world's first public demonstration of such a display.
The display is made using the company's DynamicPixelTuning technology, that makes it possible to create full-color or tunable-color monochrome displays using identical pixels from a single wafer. The company's PoroGaN material allows a modulated current to be leveraged to emit visible light covering the entire color spectrum on a single microLED chip.
Porotech also announced that it will showcase a 0.26" DPT microdisplay with a pixel pitch of under 5 micron at CES 2023 in Las Vegas.
In April 2022, Porotech demonstrated 1920x1080 monochrome microidsplays, that achieved over 2 million nits of brightness. The company said that that it was the first to demonstrate all three-color light emitting elements made from a single material and toolchain. Those display included Porotech's native red InGaN display at 614-625nm wavelength.
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. In May 2022 the company announced its DynamicPixelTuning technology.
