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).

AUO demonstrates a 8" 169 PPI Micro-LED display prototype

AUO demonstrated a micro-LED display, which it says is the world's highest resolution full-color TFT micro-LED.

The 8" panel features a resolution of 1280x480 (169 PPI). The micro-LEDs use blue LED chips with color conversion, on an LTPS backplane. AUO did not disclose any roadmap to commercialize this technology.
