Battery-Free Glasses for 3D Televisions

Posted: Sep. 19th, 2012  |  By Michael Pearse

When looking through the complaints about 3D televisions, the requirement for specialized glasses is an annoyance that continues to keep many people from upgrading the TV. While progress is being made to get 3D TVs without requiring glasses to market, that is still a few years out. However, the battery-charged glasses are just about to become obsolete as passive glasses, like those used at movie theaters, are soon going to be used on consumer televisions.


The benefit of these passive glasses for consumers is two-fold. First, the price of the glasses will drop dramatically as production costs are going to drop, which will make owning multiple pairs not a luxury but standard. Second, without having to worry about whether the glasses are fully charged or not let consumers watch as much 3D content as they want, with no glasses swapping or stopping a program to charge the battery.


The culmination of these efforts should result in further 3D TV purchases, which, in turn, will lead to more research and development of glasses-free sets.
