In January 2019 Xiaomi unveiled a new prototype smartphone that uses a tri-foldable OLED display. The company did not disclose much information, but a report from Taiwan suggested that the OLED supplier for this prototype was Visionox.
In an interview with China Daily a Visionox VP confirms that Visionox supplied the foldable OLED prototypes to Visionox. He also says that Visionox supplied Xiaomi with the innovative OLED displays with under-the-screen camera (seen in the video below).
Visionox says it is accelerating its OLED expansion plans as it sees rising demand for OLED displays. The company disclosed it is proving ZTE with the 6.47" 1080x2340 AMOLED displays for its Axon 10 Pro 5G smartphone. Visionox is also the supplier of the foldable OLEDs used by Nubia in its Alpha foldable device.
Visionox is advancing its OLED technology very quickly. In March 2018 it demonstrated its foldable OLEDs for the first time - with a 7.2" folding OLED prototype, and is now already producing the 4" foldable OLED in the Nubia Alpha commercially (although likely at very low volumes).
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.
