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.

VueReal raised $8.5 million, to build an advanced fabrication center in Canada

Micro-LED microdisplay developer VueReal announced that it has raised $8.5 million from Sustainable Development Technology Canada (SDTC) that will be used to further develop its technology. VueReal will also build advanced nano technology fabrication center in Waterloo, Canada, in partnership with Angstrom - a Canadian-based PVD and CVD equipment maker.

VueReal says that its next step is to build an integrated pilot production system that will use the company's proprietary sub-10 micrometer, high-efficiency, Solid Printing process at commercial volumes. The company will also work to enhance the performance of its Micro-LED microdisplays.

JBD unveils a 1 million nits MicroLED microdisplay

Shanghai-based Micro-LED microdisplay developer JBD demonstrated its latest Microdisplay that achieve an extremely high brightness - 1 million nits. The display resolution is VGA. JBD is already offering its monochrome VGA micro-LED microdisplays commercially (but we're not sure if these are the 1 million nits ones).

JBD's current micro-LED process still suffers from low yields, but the company hopes to achieve at least a 70% yield in the future, which will enable it to bring prices down to about $10 to $20 per display.

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.

Digitimes: Apple is collaborating with TSMC on Wearable/VR/laptop Micro-LED displays, first displays will enter production by early 2019

Earlier this month Bloomberg reported that Apple is progressing with its Micro-LED development project, and has already managed to produce promising display samples. Now Taiwan's Digitimes reports that Apple is collaborating with Taiwan Semiconductor Manufacturing Company (TSMC) towards mass production of Micro-LED panels.

Apple and TSMC are focusing on small-sized micro-LEDs on silicon based backplanes, targeting both wearable devices and AR applications. The Micro-LED microdisplays for AR applications will be around 0.7-0.8 inch in size, while the wearable panels will be larger at 1.3-1.4 inch.

eMagin: Micro-LED is not ready yet for microdisplay applications

OLED microdisplay maker eMagin reported its financial results for Q4 2017, and during the quarter's conference call its CEO, Andrew Sculley, discussed Micro-LED for microdisplays.

eMagin actually did a research in this area with a University and has some patents towards micro-LED based microdisplays. However according to Andrew this technology still faces some challenges and it may take several years before Micro-LEDs could be applied to microdisplays - unlike TVs or larger displays which are already on the market.

Micro-LED microdisplay developer VueReal raises $10.5 million

Micro-LED microdisplay developer VueReal announced the initial closing of its $10.5 million Series A funding round, led by the venture arm of a large Asian company and a leading North American vendor focused on startups with emerging technology.
