Samsung has successfully managed to develop a flexible OLED display lamination method that the company can use to create truly bezel-less foldable phones. Not just that, the new method will also allow the company to reduce the overall thickness of the display, which will effectively make the screens more affordable to develop.

Samsung is using technology similar to inkjet and it sprays adhesive instead of requiring a number of transparent adhesive tape layers to be inserted which takes more time, and of course, is more expensive.
