AU Optronics have been showing new microLED display prototypes, and the following video from Insight Media shows the company's booth and new displays at SID Displayweek 2022.
You can see AUO's stretchable 141 PPI display (a very interesting demo, developed together with PlayNitride), the rollable 14.6" 2K (202 PPI) LTPS microLED display, AUO's 1.4" circular 454x454 (326 PPI) microLED another stretchable microLED, this one 6.45" in size with a 900x450 resolution (163 PPI), and finally AUO's 17.3" 2000-nits 1280x720 transparent (60% transparency) microLED prototype.
The transparent display was demonstrated in a two-screen setup, in front of another display to create a 3D effect (the demo included eye-tracking to achieve greater impact).
In 2021 the company demonstrated a smaller transparent display, which was even brighter at 3,000 nits.
