Report: Samsung and LG are each working on a display with four curved sides22
According to today's report, Samsung was originally going to use this new screen on the Apple iPhone 8 this year. Recently, Samsung signed a two-year contract with Apple, promising to supply the company with as many as 92 million OLED panels for this year's tenth anniversary edition of the iPhone. We recently showed you 3D models made of the iPhone 8, which were produced by a third-party. The images showed the iPhone 8 with a flat front screen, and no bezels on the top or bottom. Other reports indicate that Apple has decided on a flat OLED display for the anniversary model. Problems in the lamination process are believed to be behind Apple's decision to go with a flat screen for the iPhone 8. The lamination adds film-like material to the glass in order to protect it.
One major issue is preventing Samsung and LG from making further progress developing a display with four curved sides. There is a spot in each corner where the touch function will not work Current lamination techniques do not support a display with four curves. This means that for now, Apple will have to stick with a flat OLED panel for its 2017 premium handset. And if Sammy wants the Samsung Galaxy S9 to come with a display featuring four curved sides with no bezels on top and bottom, it will have to come up with a new lamination process.
