Sony didn't have too much to show at CES this year, but it did come packing one surprise: a new, absurdly thin and sharp 4K TV. The horrifically named XBR-A1E (try remembering that one a few minutes from now) features a 55-inch, 65-inch or 77-inch OLED panel capable of spitting out Ultra HD and high dynamic range (HDR) with ease. The most intriguing part, however, is "Acoustic Surface," which integrates the speaker into the screen itself. That's possible because of how ridiculously thin the set is. In fact, LG Display took a similar approach with its Crystal Sound prototype.
