Glasses-free 3-D television is still a long way from the market.

Television manufacturers and content producers started out the year pushing 3-D television hard, hoping to ride the wave of success enjoyed by the 3-D movie Avatar. Though glasses-free 3-D is still some ways away, manufacturers hope to entice consumers with a flurry of products that make the best of the difficulties with bringing 3-D content to the small screen.
Producing a 3-D television that doesn’t require glasses is “impractical for the foreseeable future,” says Peter Fannon, vice president of corporate and government affairs for Panasonic.
Demos featuring glasses-free 3-D television technology have yet to pan out into real products. Two years ago, Mitsubishi attracted attention by showing off glasses-free 3-D research technology, but the company has no products based on the work.
Fannon says that a key trouble with glasses-free 3-D is that it would significantly raise production costs. Most glasses-free TV displays use a lenticular lens, which gives off light at different angles–so that a different image reaches each eye. Such a display requires images of the same object to be captured from many different angles, forcing content producers to film and process the same scene from a dozen or more angles at a once. “That’s a production cost no one can bear,” he says. Lenticular lenses can also distort a picture, and viewers often have to watch from a specific angle.
