V-Technology showed a Fine Metal Mask (FMM), or, as it calls it a Fine Hybrid Mask (FHM) at the Finetech show in 2017 (FMM Improvements Allow Higher Resolution) that can support displays up to 738 ppi. Now, according to OLED Info, the company has said that it has started an investment programme in a new subsidiary to make the masks and will invest a total of ¥5 billion ($47 million) over the next few years. The facility should be complete in August, with deliveries to start in October 2018.
The company has also acquired Lumiotec, an OLED lighting developer that was previously owned by Mitsubishi Heavy Industries, ROHM, Toppan and Mitsui, the site said.
