Porotech, a developer of microLED and GaN-based semiconductor technology, is showcasing the world’s first set of native indium gallium nitride (InGaN)-based Red, Green and Blue microLED displays at 1920 x 1080 resolution with at least 2 million nits of brightness (≥ 2M nits) at Touch Taiwan event.
Porotech is the first in the industry to demonstrate all three-color light-emitting elements produced with a single material and toolchain, enabled by its game-changing microLED technology platform, PoroGaN™ – including a native red InGaN display at 614-625nm wavelength. The platform’s proprietary subsurface porosity technology highlights a breakthrough to drastically increase brightness and efficiency in all three primary colors, while its scalable architectures simplify the manufacturing processes thus reducing cost, which are all critical requirements for the commercialization of microLED displays for next-generation consumer AR/MR/VR glasses, smart wearables and smart displays.
Until now, the requirement to mix multiple material systems has complicated the manufacture of full-color displays in the micro (µm) or nano pixel (nm) space, due to the marked drop in the efficiency of the red sub-pixel with decreasing pixel size. “Our deep material technology has unlocked the ability to produce microLED’s with high brightness and color uniformity for RGB grown on a single InGaN-based material system and produced with a single tool chain. This will enable a wide range of use cases for optical system designs while optimizing microdisplay manufacturing and improving yield for mass production,” Porotech CEO and Co-founder Dr. Tongtong Zhu said. “Meanwhile, we have been working on full-color InGaN-based monolithic microLED displays and expect to be making an exciting announcement to the public very soon,” Zhu added.
Enabled by the proprietary technologies, PoroGaN platform has made it possible to produce a 614-625nm wavelength InGaN red display, as well as 536-543nm InGaN green and 444-447nm InGaN blue displays. The company will be demonstrating how the platform facilitates emission across a wide spectrum of wavelengths, from blue to green and into the reddest red ever natively produced from InGaN at Touch Taiwan.
Recently, Porotech has successfully created the world’s first microLED display based on native red InGaN – with an active area of 0.55 inches diagonally and a resolution of 960×540. In early 2022, the company secured $20 million Series A investment to accelerate global expansion and mass production of its microLED products.
Porotech will be exhibiting at Touch Taiwan – Display International Booth # M402, Hall 1, 4F at the Taipei Nangang Exhibition Center in Taiwan, on 27-29 April. Contact Porotech at info@porotech.co.uk to arrange a one-to-one demo meeting.
After the Touch Taiwan exhibition, the company will introduce its dynamic pixel tuning capability to address the full color spectrum at SID Display 2022 in San Jose, California, USA.
