Taiwan's AUO (AU Optronics) was formed in 2001, by the merger of Acer Display and Unipac Optoelectronics. Later in 2006 AUO merged with Quanta Display. AUO is the world's number 3 manufacturer of TFT-LCDs, and also produces OLED display in low volume.
AUO has an active micro-LED R&D project, and in 2018 it demonstrated what it claims to be the world's largest TFT-driven full color Micro-LED display prototype at 12.1".
The latest AUO MicroLED news:
Digitimes posted an interesting article, stating that AU Optronics is set to adopt mini-LEDs in its LCD display backlighting units in 2018 (mostly for higher-cost applications such as gaming notebooks and professional displays). The company, however, still sees many challenges towards the commercialization of micro-LED displays.
AUO's chairman and CEO, Paul Peng, estimates that Micro-LED will still be in the development stage in 2018-2019, and while we will starting seeing many prototypes and even product samples, real commercial displays will take longer to appear. Peng says that Micro-LEDs, with their higher cost, will initially be adopted for AR and VR devices which will enable to pay a premium for the advantages over OLEDs (resolution and efficiency, probably).
