Fancy a TV that you can roll up, just like a projector screen? Well, we’re inching closer to that future now that LG Display has developed an 18-inch flexible OLED panel with a 1,200 x 810 resolution, and which can be rolled up to a radius of 3cm. LG clearly sees this breakthrough important as it works towards rollable TVs of more than 50 inches in the future. For tech nerds, the aforementioned panel uses high molecular substance-based polyimide film as the backplane (instead of conventional plastic) to achieve its 30R curvature radius. This polyimide film also helps in reducing the panel thickness, which in turn, improves its flexibility.
