A new industrial milestone has been reached with the achievement of full color microdisplay on a single panel.
Highlights of the news:
Based on Porotech's Dynamic Pixel Tuning® (DPT®) technology, this is the first single-panel, full-color microdisplay in the world that can be used for augmented reality (AR) applications.
Utilizing a patented driving technique created by Porotech, the new, cutting-edge active-matrix 0.26-inch microLED display with a resolution of 1280x720 quickly displays red, green, and blue light to allow a full-color RGB display and vividly saturated hues.
A single LED epitaxial growth and a one-step wafer-to-wafer bonding to the CMOS backplane have eliminated important microLED production hurdles, enabling full color native microLED displays.
Porotech earned the prestigious Innovation Zone Award last year at Display Week 2022, where the business first showcased its revolutionary Dynamic Pixel Tuning technology. By introducing the World's First Monolithic Full Color MicroLED Display based on DPT this year, Porotech intends to capitalize on that success.
UK's Cambridge is under embargo until 00:01 (BST). May 18, 2023Porotech, a world leader in Gallium Nitride (GaN) semiconductor technology and microLEDs, has unveiled the first single-panel, full-color microdisplay that may be used for augmented reality (AR) applications. The microdisplay is based on Porotech's revolutionary Dynamic Pixel Tuning® (DPT®) technology, which, when driven with a certain current density, allows DPT microLED pixels to emit any visible hue. The 0.26-inch monolithic full-color microdisplay and an AR development platform will be unveiled by Porotech from May 21–26, 2023, at SID Display Week in Los Angeles.
The new, cutting-edge active-matrix 0.26-inch microLED display with a 1280x720 resolution is being unveiled by Porotech, which has already shown how a DPT pixel can produce the entire spectrum of visible colors. It uses a proprietary driving technique that Porotech developed that quickly displays red, green, and blue light to enable a full-color RGB display and richly saturated colors.
Eliminating major manufacturing obstacles
The 3.5-micron microLEDs are made on a 4.5-micron pixel pitch using current backplane technology. Porotech's microLEDs eliminate the need for subpixels, allowing for a bigger emitter size without sacrificing resolution. Full color native microLED displays can now be unlocked with a single LED epitaxial growth and a one-step wafer-to-wafer bonding to the CMOS backplane thanks to Porotech's DPT technology. This eliminates the intricate and low-yield production obstacles seen in other methods.
In reaction to displays' future
With advantages including increased brightness, energy efficiency, contrast ratio, longer device lives, smaller displays, and higher pixel densities and resolutions, microLEDs are the most promising option for displays in AR glasses in the future. A single-panel full-color solution with a high pixel density and a small form factor has been long sought for and anticipated by many AR developers.
As only DPT pixels can fulfill the requirements, performance, durability, and affordability necessary for AR glasses, Porotech's CEO and founder, Tongtong Zhu, stated: "This new single panel full color microdisplay marks a significant milestone for Porotech and the entire microLED industry." Additionally, Porotech's DPT technology expands the market for microLED display applications beyond AR/VR, such as big panel displays for commercial outdoor signs, smart watches, smartphones, tablets, and flat panel TVs.
For next-generation AR glasses or any other display applications that may make use of Porotech's DPT technology, we invite prospective partners and clients to collaborate on the development and design of monolithic full color microdisplay panels, projectors, and light engines.

With non-optimized backplane designs, the DPT pixel provides a revolutionary method that enables full color without sacrificing pixel density. For direct-view LED applications, DPT pixel designs may be used as separate devices that can be mass transferred or integrated into monolithic display systems.
