Ok, this display at the CES Unveiled event has been wrapped in some funky curved frame yet, but Samsung is showing it off because by producing a 1080p 240Hz LCD with edge lighting only on two sides instead of the traditional 4, it uses 52 percent less energy than existing models. While we still prefer plasma or LED backlighting for picture quality, viewed in the light of this showcase it didn't seem to particularly suffer compared to its edge LED lit brethren.
