OTI Lumionics to supply its CPM mateirals for under-the-OLED camera displays

OTI Lumionics announced that its latest ConducTorr Cathode Patterning Material (CPM) materials will start shipping by the end of 2020 to customers, which will use these to create OLED displays with under-the-display camera and face unlock technologies.

OTI says that the first mobile devices using OTI’s CPM materials are expected to ship in 2021. Last month we reported that Visionox will soon start shipping AMOLED displays with an under-the-display camera, it could be the Visionox is OTI's first customer. OTI received a strategic investment from LG recently, which could hint that LG could be OTI's customer as well.
