Ever since the successful launch of Avatar, many manufacturers are aiming to bring the 3d environment into your home. In recent years, the development 3d televisions became prevalent and made more improvements to home movie viewing. For anyone who wants to know how three dimensional technology works on TV, awareness on 3d glasses must be taken into consideration. For many critics the increasing availability of 3d contents for 3d TV networks and channels has affected the growth of interested individuals to have 3d televisions at home. People have also raised the questions on why do we need 3d glasses when watching 3d movies on our television sets. The answer lies on how our eyes project the images and how the brains interpret the images for our eyes to perceive one image in three dimensional characteristics.
The type, model and the brand of television or projector will determine what kind of 3d glasses you must secure for your entertainment devices. Most of the manufacturers like Samsung, Sharp, Mitsubishi and Panasonic developed televisions under active shutter technology on their LCD, DLP and Plasma monitors. While others like LG are now promoting the passive glasses for their televisions. Many manufacturers are providing 3d glasses as part of the package to customers who will buy the television set. Others will also require you to purchase it as accessory if ever you need another pair. Prices for these may vary according to the type and the features that the manufacturers provide.
Customers must also be aware that the glasses branded for one manufacturer will not work for the other. This means that the 3d glasses made by Panasonic will not work on your Samsung 3d television. So if you are planning to borrow your neighbor’s glasses instead of buying yours it wouldn’t be possible for you to do so if you have different brands of TVs. However other people usually secure for their own glasses for hygienic purposes. Another third party manufacturer of 3d glasses which can be use on both commercial and consumer application have developed universal 3d glasses that work on the most recently available 3d television that uses the active shutter technology.
The new technology now enables viewing 3d images on televisions without using the glasses but the technology is not practical. The application is also known as AutoStereoscopic Dispalys. These prototype displays are too much expensive these days and in most cases when viewing a 3d movie on televisions without 3d glasses the audience must stand in the middle to experience the 3d technology making it unsuitable for group viewing. More progress is also being implemented on mobile phones and portable gaming devices. The progress of this technology is far more encouraging when Sony, LG and Toshiba has demonstrated the 56 inches 3d TV with prototype 3d glasses free in a larger screen at the 2011 Consumer Electronic Show. However this kind of 3d viewing still needs more development in the settings which are now studied by experts before they will be launched out in the market.
