Samsung Display is expected to begin foldable OLED production towards the end of 2018, as Samsung Electronics plans to begin selling foldable phones in the beginning of 2019. A new report from Korea's ETNews gives some new information on Samsung's plans.
According to ETNews, Samsung will soon be ready to start producing foldable OLEDs in a new pilot line in its A3 flexible OLED line. In 2018 the company will only be able to produce 100,000 units, and in 2019 the capacity will be about 1 million. It seems that Samsung is in a hurry to have a product out, and is currently ready to start production with low yields and high production costs (according to GBI estimates, the first foldable phone/tablet will cost over $1,800).
ETNews further says that the first phone design will have a large 7" display that will fold inwards and vertically (like a clamshell phone). The display will not fold fully, however - when folded a third of the display will still be visible and will thus operate as an external display.
