Sharp Debuts 4-Color 3-D TVs, No Glasses Needed
At the Consumer Electronics Show January, Sharp brought a new four-color TV instead of a new 3-D TV like most of the other major manufacturers. Today Sharp remedied that problem by showing off some 3-D TVs of its own.
Sharp demoed some large 3-D screens that also incorporated the Quattro four-color technology in sizes up to 60 inches. The fourth color is yellow, which combines with the traditional red, green and blue pixels to create the "industry's brightest" screens, according to Sharp.
Sharp also unveiled some smaller 3-D screens intended for netbooks, tablets and similar devices. Sharp's demo screen was 10 inches, perfect for a netbook, but differed from the larger screens in that it did not require glasses to display a 3-D image.
The smaller screens use a technology, called parallax barrier, to simulate a 3D image without the need of glasses by using a material with special slits that lets each eye see different pixels in the image.
Sharp plans to sell the 3-D TVs in Japan this summer, with worldwide availability sometime after that.
