The phone may have a 7.3-inch OLED screen that folds inwards. Currently, Samsung Display is testing prototypes of this screen to ensure that the screen does not get damaged after repeated folding.
Informed sources also said that at this week's CES show, Samsung also plans to show the core customers in a private meeting this folding screen.
Some analysts said the upcoming foldable phone may become the most expensive Samsung smartphone ever.
Last April, Kim Tae-woong, chief engineer of Samsung Display, once said that folding screen phones may not be available until 2019 due to the still-popular sales of curved screen phones and some technical challenges.
Chung Won-seok, an analyst at investment firm HI Investment and Securities, also believes that Samsung will introduce a foldable screen in 2019 because there is no need to sell foldable phones too early. "The current surfacing screen enjoys a 20% operating profit, and Samsung will hit the next trump card (foldable screen) when the demand for surface mount screens drops," he said.
Collapsible screens are seen as a trend for smartphones in the future. In addition to Samsung, Apple Inc. and China's millet companies are also developing related technologies.
