AU Optronics released this nice video that shows its latest microLED display prototypes. First up is the company's 12.1" automotive display. This one features a 1920x720 (169 PPI) resolution, and is made on an LTPS backplane. This display was shown first in 2018.
The second display in the video is the flexible microLED developed in collaboration with PlayNitride. This is a 9.4" 228 PPI display, again driven by an LTPS backplane.
In early 2019, AUO announce it plans to accelerate its development of Micro-LED products. 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.
