Glo demonstrate its LTPS and CMOS MicroLED displays

US and Sweden based Glo has been developing Micro-LED displays on both LTPS and CMOS (microdisplay) backplanes for many years. The company has been rather queit until now (even though the 2017 investment from Google created some buzz).

Glo: MicroLED vs OLED, LTPS demo 2019

Glo has now started to disclose its technology and achievements. At CES 2019, Glo demonstrated two displays. First up is the 1.5-inch smartphone type display you can see in the image above. The 264 PPI 120Hz display is produced on a LTPS backplane and produces 4,000 nits brightness - you can see how it is much brighter compared to the LGD OLED in the Apple Watch next to it (1,000 nits max).

Fuji Chimera: micro-LEDs are not yet ready to take over the AR microdisplay market

Fuji Chimera Research Institute says that the global microdisplay market reached $161 million in 2018, led by LCoS panels (59.7%) and OLED panels (27.8%).

While some analysts expect Micro-LED to take over the AR microdisplay market, Fuji Chimera says that the technology is not mature enough and there are some technology challenges to overcome still - including those in epitaxial wafer process, mass transfer, defect detection and current drive.

Yole's technology & market analyst Zine Bouhamri was kind enough to discuss Yole's Micro-LED views with us. Mr. Zine is is a member of the Photonics, Sensing & Display division at Yole and he's deeply involved in the business development of the Displays unit activities.

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.

Yole: LCoS, DLP and MicroLED displays to dominate the AR market

Yole Developpement says that there are still several challenges to solve before AR systems that are good enough for mass usage are developed. Yole sees the market finally emerging in 2022 or 2023.

AR display forecasts (2018-2027, Yole Developpement)

Yole sees three display technologies dominating this market - DLP, LCoS and MicroLED displays. OLEDs are very promising for this market as of today, but by the time AR systems are mass produced (2022/2023) MicroLED displays will prove better than OLEDs.

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.
