AUO and PlayNitride co-developed a 9.4" 228 PPI flexible automotive-grade microLED display

AU Optronics and PlayNitride announced that the two companies have developed a 9.4" 228 PPI flexible microLED display. The new display is driven by an LTPS backplane and the two companies say it delivers a large color gamut, is weather resistance and it is suitable for automotive applications.

AUO and PlayNitride has been collaborating on microLED display technologies for many years. In early 2019, AUO announce it plans to accelerate its development of Micro-LED products. The company previous prototype was a 12.1" 1920x720 (169 PPI) panel. In September 2019 AUO's president said that he expects Micro-LED displays to enter the market within 1-2 years, starting with large-area signage and small-sized VR displays.

eLux's fluidic microLED technology and business explained

USA-based eLux was established in 2016 as a spin-off from Sharp Labs of America, to commercialize a unique MicroLED production technology. The company was in stealth mode for a few years, and is now finally discussing its technology and business. We talked to the company's president and CEO Jong-Jan Lee, who explains the company's technology, status and plans.

eLux's technology is based on a unique approach that moves microLEDs from wafer to the target substrate without the need of a pick-and-place process. The so-called fluidic process uses microLEDs dispersed in liquid and wells built onto the substrate. The microLED dispersion is spread over the substrate and the LEDs simply fall into place - a sort of self-assembly process, which can be seen in the video above.

Japan Display to demonstrate its first microLED prototype, developed in collaboration wth Glo

Japan Display announced that it is developing micro-LED display technologies, and the company will unveil its first prototype at FINTECH Japan 2019 in early December. JDI will show a 1.6" 300x300 (256 PPI) display that is based on the company's own LTPS backplane with microLED chips developed by Glo.

Here is Glo and Kyocera's 1.8" microLED prototype

In June 2019 Micro-LED developer Glo announced a partnership with Japan-based display maker Kyocera to demonstrate a 1.8" Micro-LED display. Here's Kyocera's booth at CEATEC 2019 that features this display (03:00):

The Glo microLED display features a resolution of 256x256 (200 PPI), a peak luminance of 3,000 nits and a color gamut of 81% Rec.2020. The display's frame rate is 240Hz and the response time is 7 usec or less. For this demonstration panel, Kyocera provided the LTPS backplane and driving technology while glo provided its InGaN RGB micro-LEDs and its transfer technology.

Lumiode explains its truly-monolithic microLED microdisplay technology

US-based Lumiode has been developing MicroLED Microdisplays for many years, but the company has been very quiet and did not disclose much about its technology. We have recently met with Vikas Dhurka (VP Marketing) and Eddy Hsu (director of Display Systems) who explained and demonstrated the company's technology.

Lumiode has developed a unique technology for the fabrication of TFT backplanes directly on top of Micro-LED arrays. This enables an entirely monolithic process (with no wafer bonding) to create highly bright and efficient microdisplays.

Glo partners with Kyocera and demonstrate a 1.8" Micro-LED display

US and Sweden based Micro-LED developer Glo has partnered with Japan-based display maker Kyocera to demonstrate a 1.8" Micro-LED display that features a resolution of 256x256 (200 PPI). For this demonstration panel, Kyocera provided the LTPS backplane and driving technology while glo provided its InGaN RGB micro-LEDs and its transfer technology.

Glo says its micro-LED technology enables the production of displays ranging from micro-displays to smartphone-sized panels, and have demonstrated several such panels at SID DisplayWeek 2019.

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).
