AU Optronics announced that it will demonstrate a 12.1" LTPS micro-LED display prototype next week that features a resolution of 1920x720 (169 PPI). It seems that this is the same display shown at IFA 2018.

The 2018 display used blue LEDs with color conversion, which achieved "marvelous color performance", according to AUO.

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.

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 quiet until now (even though the 2017 investment from Google created some buzz).

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 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.
