Plessey signs deal with Facebook to dedicate all of its MicroLED operations to support Facebook's AR project

UK-based GaN-On-Si MicroLED microdisplay developer Plessey Semiconductor announced a partnership with Facebook - in fact Plessey will dedicated all of its manufacturing operations to support Facebook with its own product development.

Plesssey says that its displays will be used to support Facebook's prototypes, and the company will develop new microLED technologies to future AR/VR applications.

We talk MicroLED displays with VueReal's CEO

Canada-based VueReal is a startup company that develop Micro-LED based microdisplays. The company's Continuous Pixelation micro-printing technology offers high density displays, high production yields and a simple design.

VueReal's founder and CEO, Reza Chaji, was kind enough to answer a few questions we had on the company's technology and business.

Reza, thank you for your time. Can you explain VueReal's micro-printing process and technology?

VueReal’s solution is a true printing process where you do not need to pick LEDs for each transfer. It is based on a cartridge design by VueReal that releases the LEDs selectively into the substrate.

Plessey and Compound Photonics produce first microLED display modules

In October 2019 MicroLED microdisplay developer Plessey Semiconductor announced a partnership with Compound Photonics to co-develop microLED display modules. The two companies announced today that the first fully addressable microLED display module was produced and tested.

Plessey says that this first functioning microLED prototype validates the successful bonding of Plessey’s GaN-on-Si microLED array wafer to CP's high-performance 3.015 micron pixel 1080p backplane wafer. The module that was produced (shown above) is a 0.26" FHD monochrome native-green display.

Plessey and WaveOptics to co-develop a microLED optical module for next-generation smart glasses

UK-based GaN-On-Si MicroLED microdisplay developer Plessey Semiconductor announced a new partnership with waveguide designer WaveOptics to develop new optical modules for next-generation smart glasses.

The module will incorporate Plessey's high brightness green Full-HD microLED displays with WaveOptics' Katana waveguide technology and projector design. Plessey says that this module will be the smallest and lowest mass AR display module available on the market.

MICLEDI explains its MicroLED microdisplay technology and business model

Earlier in January, Belgium-based MICLEDI announced that it raised 4.5 million Euro to develop next-generation MicroLED microdisplays for AR applications.

We had a short talk with MICLEDI's CEO, Sean Lord, who helped us understand a bit more about the company's technology and goals. MICLEDI is indeed focused entirely on the AR market, and so aims to provide display engines that will be extremely bright (over 10 million nits), efficient, and with a very small footprint. In addition costs are also important for the future consumer AR market.

Yole: microLED shipments to reach over 125 million panels by 2027

Market analysts at Yole Developpement say that microLED shipments will reach over 125 million panels by 2027. In their aggressive scenario, shipments will reach almost 450 million.

Yole says that microLED technologies are advancing rapidly - and on all fronts, but there are still many challenges to overcome before mass production arrives. MicroLED makes a strong case for the AR, smartwatch and automotive market. For the smartphones and TV markets it is less clear whether MicroLEDs could succeed.

AU Optronics sees Micro-LED displays entering the market in the next 1-2 years

AU Optronics president, Paul Peng, says that he expects Micro-LED displays to enter the market within 1-2 years. The first displays will be large-area signage and small-sized VR displays. Micro-LEDs for the automotive market will take longer to commercialize - around 5 years.

AUO 12.1'' LTPS micro-LED prototype (August 2019)

AUO recently demonstrated a 12.1" LTPS micro-LED display prototype that features a resolution of 1920x720 (169 PPI). AUO discloses that this display was produced using the company's self-developed transfer process that can move 50,000 - 60,000 LEDs per transfer (AUO did not detail the time it takes to perform a single transfer, though). AUO is now developing repair technology to take care of damaged LEDs.
