Three-dimensional television and the like got a major marketing push nearly two years ago from the consumer electronics and entertainment industries, yet the technology still has major limitations. Whereas glasses-free 3-D on television screens and computer monitors is seen as crucial to generating widespread interest in new consumer electronics, for the most part, viewers still need to wear glasses to experience stereoscopic 3-D images, although glasses-free TVs are starting to hit in Japan.
The use of 3-D sans specs has been much more successful in smaller screens such as smartphones and portable gaming devices. But these LCDs must be backlit to work properly—which can be a big battery drain and limits how small the gadgets can be made.
