LG Display Bows World-First 77-Inch Flexible, Transparent OLED Panel With 4K

With Thursday’s announcement that LG Display developed the world’s first 77-inch flexible and transparent Ultra HD OLED display, the panel maker exceeded its own 2014 forecast when it said it was “confident” it would fashion a flexible, transparent OLED panel with 4K resolution bigger than 60 inches by 2017. The new display has 40 percent transparency, LG Display said in the Thursday announcement. It also has a curvature of 80R, said the panel maker. That means the panel can be rolled up to a radius of 80 millimeters (3.1 inches) without damaging its functionality, the company said. The 2014 announcement predicted the flexible transparent large-screen OLED display of 2017 would have a curvature of 100R. LG Display representatives didn’t comment Thursday on why the company waited until now to unveil the innovation rather than announcing it at last month’s Display Week conference, where it showcased a 77-inch wallpaper TV and a smaller transparent OLED display prototype that wasn't flexible (see 1705240047).
