Samsung has demonstrated a prototype 40-inch LCD (liquid crystal display) that is just 7.9 millimeters thin. That beats an 8mm-thin, 32-inch prototype from Philips that previously held the world record for the thinnest LCD.
Both prototypes gained some thinness by having the tuner and some other electronics separated into a box that's intended to sit alongside the screen. It's unknown when either might become a commercial product.
Samsung has also demonstrated a prototype 52-inch LCD that is 9.9mm thin. That matches the thinness of Sony's ZX1, which is the thinnest LCD television yet to be announced as an actual product.
