Porotech has developed a single pixel that can create a full range of colours simply by changing how the pixel is driven, called DynamicPixelTuning® (DPT®). This technology can be seamlessly incorporated into an already established market. Porotech has developed several products including full-colour projectors, microdisplay panels, AR glasses, and epitaxy wafers. The company’s panels offer higher resolutions as they are sub-pixel-free, and a longer lifespan due to the use of inorganic materials. Porotech’s projectors and AR glasses can approach currently available optic systems and waveguides, their tuneable wavelength signifies high adaptability to the current market, and the full colour projector is not limited by the type of waveguide used. Compared to the traditional three monochrome panels needed, which impede smooth mass manufacturing, only a single panel is required, meaning manufacturing ease and smaller projectors.
Porotech's unique gallium nitride (GaN) material engineering and production technique enables the world's first commercial native red LED epiwafer for micro-LED applications. Micro-LED technology offers significant brightness, efficiency, and image definition improvements, crucial for AR and head-mounted displays. Traditional red LEDs faced efficiency challenges due to small device size. Porotech's unique porous GaN semiconductor material extends InGaN LED emission range, meeting red display needs, and scaling for micro-LED technology. This breakthrough enables highly efficient full-color micro-LED displays for large area displays, mobile phones, smartwatches, and more. Positioned for success, Porotech drives micro-LED technology and redefines display possibilities.
Porotech is delivering novel microLED display technology using its porous gallium nitride (PoroGaN®) platform technology in combination with complimentary epitaxial design. This has enabled blue, green and (most critically) red emission from the same InGaN material platform, delivering monochrome displays with very low wavelength shift (<10nm for blue, <2nm for green and <30nm for red). Further still, Porotech have used the same approach to deliver microLEDs with deliberately high wavelength shift (<150nm), allowing the wavelength emission of individual LED emitters to be tuned. This DynamicPixelTuning® technology enables all colors from red to blue to be emitted from identical pixels/emitters on the same wafer, removing significant roadblocks to full color display manufacture - particularly in the case of microdisplays for AR/MR applications. In terms of the display engine and system level design the technology can be exploited further by simplifying the driving, light extraction, waveguide design etc… since only one ‘type’ of pixel needs to be designed for. In general, much greater design freedom can be employed at all stages in the manufacture of the final product in order to meet consumer performance requirements.
Porotech is revolutionising microLED displays with its DynamicPixelTuning™ (DPT™) technology. Each individual DPT™ pixel is a single LED emitter with tuneable wavelength emission all the way from red to blue. There are no ‘RGB’ sub-pixels, no pixel stacking architectures, no filters and no colour conversion technologies involved – full colour is possible at the wafer level, with no complex manufacturing required and no need to mix different material systems. DPT™ has been enabled entirely on InGaN-based material through Porotech’s engineered porous GaN (PoroGaN®) platform technology, which is a simple, repeatable and fully scalable process. With key microLED microdisplay manufacturing barriers removed and new realms of display system design unlocked, Porotech is positioned to deliver the microLED display solutions which will meet the demands of consumer AR.
