World’s first 'all-in-one' full-colour microLED display


Porotech’s DynamicPixelTuning tech enables a single pixel to emit across the entire colour spectrum, including white light

Porotech, a Cambridge, UK start-up focused on microLED and GaN semiconductor technology, has announced the world’s first public demonstration of an 'all-in-one' full-colour display of microLED pixels.

Porotech is pioneering the next generation of displays by using a single microLED diode for all colours, moving away from the constraints of the RGB (red-green-blue) sub-pixel model that underpins all current commercial display technologies.

Porotech’s innovation lies in its DynamicPixelTuning (DPT) technology. PoroGaN, the GaN-based material that underpins DPT, allows a modulated current to be leveraged to emit visible light covering the entire colour spectrum on a single microLED chip. Among the colours it can emit a DPT microLED is able to achieve a world first by emitting pure white colour from a single pixel.

The company thinks DPT is game-changing for the display industry at large. Through removing the need for RGB sub-pixels, DPT allows a microLED-driven display to increase overall pixel density fourfold. As a result, DPT can produce substantial gains in resolution, brightness and efficiency for every type of display. This breakthrough is of particular interest for small form factor displays that demand high resolutions, such as AR and VR displays, as well as wearable tech.

Porotech will be making the first public debut of DPT at CES 2023 in Las Vegas, where it will be showcasing a 0.26 inch DPT microdisplay with a <5 micrometre full colour pixel, followed by various other industry events in Q1 2023.

Porotech’s CEO and co-founder Tongtong Zhu says: “The world’s first full colour and all-in-one microLED display is a monumental achievement by Porotech. Mass-produced microLEDs will be pivotal for the future of displays, particularly the emerging AR and VR spaces. Our technology has solved a fundamental technical and engineering problem facing microLED display quality, manufacturability, and—most importantly—system integration.”

“This doesn’t just herald widespread adoption of consumer-grade MR, VR, and AR. In fact, DPT also offers radical improvements in TV, signage, and smart wearables in both consumer and professional contexts. By allowing pixels to move beyond RGB and quadrupling the resolution of any given display, DPT is set to unlock new uses for displays in every segment of society.”
