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).
Peng is optimistic about Micro-LEDs in the long run, it seems. He believes that Micro-LEDs are important for Taiwan's display industry as it poses a much cheaper alternative for next-gen displays compared to OLEDs or high-end LCD.
