How slim do you think TVs can get in the future? If the Samsung Needle Slim model here is of any indication, we’re probably looking at military-grade paper thin material. This 40″ full HD LED backlight TV measures a mere 3mm in thickness, which is simply amazing considering this 120Hz LCD panel comes with a 5,000:1 contrast ratio to boot. It hasn’t hit the market just yet, but Samsung ought to do so if they want to boost up their company’s profile soon.
