Plessey developed passive-matrix monochrome microLED microdisplays

MicroLED microdisplay developer Plessey Semiconductor announced that it has developed new passive-matrix monochrome microLED microdisplays. Plessey says it can customize the resolution and color of its PM displays to the customer requirements.

Plessey demonstrated its first such PM microdisplays with the 48x36 blue panel you see above. The company says it plans to introduce 384x128 monochrome and 128x128 RGB passive matrix microdisplays by the end of 2020.

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.

Mojo Vision develops microLED-based AR contact lenses

In June 2019, AR developer Mojo Vision announced that it developed a 14k sub-pixel PPI Micro-LED microdisplay, to power its upcoming AR platform. The company now revealed that its technology actually embeds the microLED microdisplay in a contact lens.

Mojo Vision has been in stealth mode until now - as the company finally revealed its technology and demonstrated a lens mounted to a handheld stick that you can peer through to see a demo loop comprised of green text overlaid on real world objects.

Plessey demonstrated its latest microLED displays and technologies at CES 2020

UK-based GaN-On-Si MicroLED microdisplay developer Plessey Semiconductor demonstrated several new microLED technologies at CES 2020. First up we have a Head Up Display (HUD) for automotive applications, that is based on a 0.7" blue monochrome MicroLED display:

This same display was demonstrated at SID DisplayWeek 2019, and uses JDC's silicon backplane. The next display is a native red InGaN microLED. This is the first time this display was demonstrated:

JBD demonstrates a 3 million nits microLED microdisplay

Shanghai-based Micro-LED microdisplay developer JBD unveiled two new Micro-LED microdisplay prototypes. First up is the JBD5UM720P-G, a 0.31" 720p (1780x720, 5,000 PPI) display that features a typical brightness of 3 million nits (!). This is a monochrome green (530 nm) display.

The second display, the JBD25UMFHD-B is a higher density display, at 10,000 PPI it achieves a 2560x1440 resolution in the same 0.31" size. This is a monochrome blue (455 nm) display that has a brightness of 150,000 nits. The display's refresh rate is 360Hz.
