Samsung Shows Off 2-Sided Edge-lit LED Display

Samsung showed off a 55-inch HDTV at CES Unveiled today, which features a novel 2-sided edge-lit LED LCD panel that could mean the future's HDTVs will be greener than ever before.

Unlike typical LED edge-lit or back-lit displays, this Samsung TV uses two LED bars to light the image, one on the left side of the panel and one on the right. A light-guide plate focuses the light from the center of the image (where the light from the two bars meet) to make the light distribution as equal as possible, so as to avoid the shadowing issues that plagued earlier edge-lit LED sets. Also, this TV supports local dimming, allowing the TV to selectively dim certain regions of the TV in order to save power and provide higher-contrast images.

As you can tell from the video, this TV is thin (10.8mm thick) and has a remarkably thin bezel. However, what sets this TV apart from Samsung's 2010 line--besides the 2-sided LED lighting technique--is the fact that this set is completely compliant with Restriction of Hazardous Substances (RoHS) guidelines and is 52% more energy-efficient than conventional LCD panels--approximately a 10% difference from existing LED edge-lit TVs.
