If you thought 3D means wearing special glasses to watch the motion, then you need a serious update. Philips is out with a range of 3D HDTVs that don't require the special glasses at all and can be viewed with the naked eye. The Quad Full TVs relay data at such a fast rate that they increase a display's screen resolution to 3840x2160 (or 8.29 million pixels), four times the number of pixels of the highest HDTV standard. Both the factors, data speed and high resolution, are incidental to the performance of a 3D TV. The large collection of pixels produce images that are important to the optical illusion and the speed puts the images together instantly. This creates a large viewing angle (160 degrees) and a very high image contrast.

Philips promises up to 46 views at once, which means the resolution is 23 times better than others viewed before. Apparently this TV will cost approximately $25,000 and Philips has already penciled in a 56" version.
