Plessey's Micro-LED display technology has been named a CES 2019 Innovation Awards Honoree

UK-based GaN-on-Si MicroLED developer Plessey Semiconductor announced that it has been named a CES 2019 Innovation Awards Honoree in the Embedded Technologies category for its monolithic microLED displays.

Plessey developed a unique monolithic micro-LED process technology that can be used to produce Micro-LED displays without a pick-and-place stage. Plessey develops two generations of micro-LED displays. The first-gen Quanta-Brite are either LCoS or DMR display that are lit by an array of micro-LEDs, which Plessey says provide a more efficient and uniform display compared to current larger-LED lit displays.

Plessey purchased EVG's production wafer bonding system

UK-based GaN-on-Si MicroLED developer Plessey Semiconductor announced a collaboration with EV Group (EVG), a wafer bonding and lithography equipment producer. As part of the agreement, Plessey purchased EVG's GEMINI production wafer bonding system to enable bonding and alignment at Plessey’s fabrication facility in Plymouth, UK.

Plessey says that the new system will enable it to bond its GaN-on-Si microLED arrays to the panel’s backplane at a wafer level. Plessey also says that EVG’s patented automated bond alignment system technology is suitable for Plessey’s requirements because it allows face-to-face alignment of the wafers with very high precision which will enable very small pixel sizes.

Plessey placed an order for Aixtron's G5+ C MOCVD tool for GaN-on-silicon growth

UK-based GaN-on-Si MicroLED developer Plessey Semiconductor announced that it has placed an order for Aixtron's AIX G5+ C MOCVD reactor that will expand Plessey's production capacity for gallium nitride on silicon (GaN-on-Si) wafers.

The new Aixtron reactor will be installed in the first quarter of 2019, at Plessey’s fabrication facility located in Plymouth, UK. The AIX G5+ C MOCVD system has two separate chambers, which enables to use either eight 6" wafers or five 8" ones. The system will be an addition to the company’s existing (and smaller) Aixtron MOCVD reactor

Plessey signs a strategic partnership with Jasper Display to use Jasper's backplane on its GaN-on-Silicon wafers

UK-based GaN-on-Si MicroLED developer Plessey Semiconductor announced a strategic partnership with Taiwan's Taiwan's Jasper Display Corp (JDC). Under the new partnership, Plessey will use JDC's silicon backplane to drive its monolithic micro-LED displays produced on the company's proprietary GaN-on-Silicon (GaN-on-Si) wafers.

In May 2018 JDC demonstrated its latest JD27E2 8" wafer, and a 0.7" Full-HD monochrome (960x540 color) microLED microdisplay that is said to be the world's brightest at 100,000 nits (JDC later demonstrated a million nits micro display). JDC's backplane allows Plessey to fabricate highly efficient and ultra-bright micro-LEDs displays.

Plessey's Quanta-Brite and Quanta-Ray micro-LED microdisplay technologies explained

Yesterday we reported that Plessey partnered with AR supplier Vuzix to bring Micro-LED display engine, Quanta-Brite, for next generation AR Smart Glasses - which Vuzix expects to introduce in 2019.

An interesting article at LED Inside explains Plessey Semiconductor's technology. The Quanta-Brite display engine is not a 'true' Micro-LED display - it is an LCoS or DMD (digital mirror) display engine that is lit by a micro-LED array and special optics. Usual LCoS and DMD displays are lit by larger LEDs, and Plessey claims that its micro-LED solution will provide a more efficient and more uniform display.

Vuzix and Plessey to co-develop MicroLED based AR glasses, aiming to commercialize a first device by 2019

UK-based GaN-on-Si MicroLED developer Plessey Semiconductor announced that it has partnered with AR supplier Vuzix to develop advanced Micro-LED display engines for Vuzix waveguide optics to enable next generation AR Smart Glasses. Vuzix expects to introduce the Micro-LED microdisplay based AR glasses in 2019.

Vuzix says that Plessey's Quanta-Brite light engine is highly efficient and bright, and will enable smaller and more efficient AR devices. The Quanta-Brite engine is based on Plessey's advanced and proprietary gallium-nitride-on-silicon (GaN-on-Si) technology, with an integrated monolithic array of RGB pixels with advanced micro-optical elements.

Plessey and Artemis to co-develop MicroLED based HUD displays

UK-based optical thin-film developer Artemis announced a partnership with Plessey Semiconductor to co-develop HUD displays that use Plessey's GaN-on-Si MicroLEDs and Artemis' thin-film coatings for HUDs.

Plessey recently announced its new licensing platform and also its intentions to bring a monolithic MicroLED display to the market in H1 2018. Plessey demonstrated an HUD prototype powered by its MicroLED display.

Plessey aims to bring a monolithic GaN-on-Silicon MicroLED display to the market by H1 2018

Plessey logoUK-based Plessey Semiconductor announced that it aims to be the first to market with a monolithic microLED based display based on GaN-on-Silicon in H1 2018. The company also announced a new licensing program that will enable third parties to license its GaN-on-Silicon microLED IP and expertise.

Plessey says that GaN-on-Silicon is the only technology that can address all the production challenges for MicroLED displays in high volumes. The company's main business will be its licensing platform, but it aims to bring to market its own displays to demonstrates its expertise.
