Porotech announces world’s first “all-in-one” full-colour microLED display

Porotech, a global leader in microLED and Gallium Nitride (GaN) semiconductor technology, today announces the world’s first public demonstration of an “all-in-one” full-colour display of microLED pixels. LEDs Magazine


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 game-changing DynamicPixelTuning™ (DPT) technology.

By using a new class of Gallium Nitride materials, DPT enables a single microLED chip to produce any visible colour. The material that underpins DPT, PoroGaN®, 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.


DPT’s potential 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.

According to a market report from Grand View Research, the global AR market size in 2021 sat at $25.33 billion and is expected to grow by 40.9% a year from 2022 to 2030. Porotech is already making waves in the AR industry, including in Silicon Valley, with the DPT technology winning ‘Best Prototype’ at the 2022 Display Week industry gathering.


MicroLEDs represent the only viable solution for the future of display technology, offering myriad benefits such as improved brightness, energy efficiency, contrast ratio, longer device lifetimes, along with greater pixel densities and resolutions. Porotech’s all-in-one pixel technology allows microLEDs to achieve unparalleled commercial viability, removing the reliance on RGB altogether - a cumbersome approach dating back to the days of cathode-ray tube (CRT) displays.


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.
