LG is about to make your flat-screen TV you paid an arm and a leg for obsolete. LG just unveiled a 55-inch OLED screen that’s thin and light it weighs 4.2 pounds and 0.04 inches in size. The 55-inch LG OLED screen is so light you can put it on a wall using just a magnetic mat. The new product is far slimmer compared with LG Display’s existing flagship 55-inch OLED panel that is 4.3 mm thick. For this to exist, it will probably have a breakout box or bar for TV functions. The ultra-slim, detachable wallpaper OLED panel was showcased at a media event held in Seoul. LG isn’t saying if it will just remain a showcase product or if it will translate into a real product.
