Hong Kong-based Truly Semiconductors started working on its AMOLED fab in 2014, and in May 2015 estimated that production will begin in Q1 2016. The fab was delayed, and a few months later it was estimated that production will begin in September 2016.
Truly have finally announced that the fab is now online, and the company is starting AMOLED mass production. Truly published the (rather overdone and weird) video you see above - and according to the video the company is targeting smartphones, wearables, VR and automotive applications.
Truly's fab is a 4.5-Gen AMOLED fab with a monthly capacity of 15,000 substrates per month - which can be expanded to 30,000 substrates. Truly also aims to start producing flexible AMOLEDs - it seems the plan is to do so towards the end of 2017. Truly says it can reach up to 500 PPI, and the first product will be a 5.7" FHD (338) one.
