Sharp latest to join 3D HDTV party, introduces first four-primary-color 3D set

You may recognize the quad-pixel technology from Sharp's new Quattron 2D televisions, and like the Quattron, Sharp's 3D sets rely on LED backlighting. The company claims that all of its display expertise has produced a 3D TV that is 1.8 times brighter than the competition, which helps enhance the effect by lessening the ghosting effect 3D images sometimes fall prey to (a.k.a. "crosstalk"), according to Sharp. Like several other manufacturers' 3D sets, Sharp's rely on pricey active-shutter glasses to provide the 3D effect for viewers.

As usual, Japan gets to put these claims to the test first, but Sharp's sets could arrive here by summer. By then, they'll have to compete against Sony and LG's 3D HDTVs in addition to the already-available models from Panasonic and Samsung. But will there really be enough people wanting to buy a 3D set by then?
