Last week Xiaomi unveiled a new prototype smartphone that uses a tri-foldable OLED display. The demonstration looks very nice, although the company did not disclose any information or specification.

Digitimes claims that Visionox is the supplier of the foldable OLEDs. Visionox is also the supplier of the foldable OLEDs used by Nubia for its upcoming (?) Alpha foldable device.

Visionox is advancing its OLED technology very quickly and had an impressive booth with many flexible OLED prototypes at SID 2018. In March 2018 it demonstrated its foldable OLEDs for the first time - with a 7.2" folding OLED prototype.

In May 2018 Visionox announced that it started to produce flexible AMOLED displays at its first 6-Gen OLED fab in Hebei. The production line has a monthly capacity of 30,000 substrates and total investment in that fab was around $4.5 billion. In October 2018 Visionox announced plans to establish its 2nd flexible OLED production line in Hefei, with a similar capacity to the Hebei line.
