If you thought TVs couldn't get any thinner, think again. LG Display's "wallpaper" panel is 55 inches wide, but less than a millimeter (four-hundredths of an inch) thick. It's so thin and light (just over 4 pounds) that it can be attached to the wall with a simple magnetic backing and then peeled off like a sticker. This level of thickness is only attainable with OLEDs, or organic light-emitting diodes. While LCD TVs require a stack of backlights, filters and tiny shutters to create their pixels, OLED TVs put all those into one layer. OLED display has enabled thin phones and other devices, but OLED TVs have been few and far between, partly because it is difficult to manufacture large numbers of them — making them astronomically expensive.
But LG Display, which showed off the super-thin TV at an event in Seoul, South Korea, claims to be fixing that problem, Yonhap News reported. Yeo Sang-deog, head of the company's OLED division, said in a press release that the company had reached a level of manufacturing efficiency in a year and a half that took a decade to achieve for traditional LCD TVs. That doesn't mean millimeter-thin TVs will be selling for peanuts any time soon (this one is just a proof of concept), but it's a step in that direction.
