The OLED TV was shown as a proof of concept at a press event in Korea. The 55-inch TV was a meagre 0.97mm thick and weighed just 1.9kg.
By mounting a thin magnet to the wall the TV can be attached like a fridge magnet. To remove it you simply peel it off the wall. It also appears to be flexible making damaging it difficult and curving it easy.
LG Display plans to keep pushing OLED and will introduce a 99-inch OLED screen this summer.
