3D TV And The Technology Behind It

There are many new breakthroughs that are have been released by the TV industry. Some of them may have a bigger impact on the consumer than others. One thing’s for sure though, 3D TV is winning over the hearts of many potential consumers. 3D technology has become one of the most popular hot topics in the technology industry. Reviews have been made with ample positive feedback being given. Nowadays, mainstream 3D films are being produced, which is why television manufacturers are stepping up development of new 3D televisions to cope with our technological demands.

Manufacturers use several methods in creating a 3D image on an LCD television screen. Some of these are quite expensive and some of them are reasonably affordable when compared with each other. There are three 3D imaging methods that will be used in the future of home theater technology and these are as follows:

A lenticular lens is like a magnifying glass that is used for viewing different angles of an image, while at the same time the images are magnified for better viewing. There are different kinds of lenticular lenses. These are the vertical and the horizontal lenses. The vertical lenses can be viewed from left to right and the horizontal can be viewed from top to bottom. For better quality of viewing, horizontal lenses are often used as our eyes lie on the same horizontal plane and we can see the image with better synchronization. Using lenticular lenses, people are free from using those glasses that are used in the theaters for watching 3d movies. The only disadvantage is that people that are near or in front of the television can watch the movie with better quality than those further away. The viewer must sit in the correct position for them to watch comfortably due to its small viewing angle.

Using the passive glass system, viewers are required to use the traditional 3D Television glasses to watch three dimensional movies. This technology uses two overlapping images. The three dimensional glasses that are being used contain polarized lenses. Passive glass systems are common to televisions which are 40 to 50 inches in size. These types of systems are already available in the market and allow viewers to watch 3D and 2D movies.

This type of system is almost the same as the passive glass systems. The only difference is that, these systems are stand alone systems. The television model is responsible for the refresh rate of the TV and using this system it is the active glass that is responsible for synchronization of the refresh rate, polarization of the lenses and the ability to allow the viewer to view the 3D images. It has the advantage of providing the viewers with the capability of watching 2D movies and then switching to a 3D movie. Using the active glass system might however cost a little bit more when compared to other methods.

The three dimensional televisions are already available in the market today. Major manufacturers have already commenced production and marketing of the 3DTV, at the moment it is more commonly available in Asia and the United States.
