Avatar movie has incredibly increased the popularity of 3D movies and 3D TV. Now a days, movies are mostly released in 3D. Movies of all genres are included in this. Although this has confused the people whether to watch the movies in 3D or not, because every person is not comfortable with 3D due to images jumping of the screen looking realistic, but one thing is sure that this technology has proved itself very impressive and worth watching.
But this technology has a problem and the problem is that you have to wear special 3D Glasses to get its true and sensational quality. Without 3D Glasses you can not get the 3D experience. Apart from that these 3D Glasses came with TV Set in a single pair. So if you want to watch a movie with your family then you should have many pairs of these glasses. An extra pair of these glasses can cost you at least $100. So this adds more expense to your budget. This is the main reason which has resulted in low sale of this technology despite its popularity. People interested in this technology are anxiously for 3D TV without glasses.
Before discussing further on the topic, it would be appropriate to know the history of 3D TV and glasses. It is interesting to know that this is issue is not new and the people have worked on this technology for almost 02 centuries. For example a stereoscope was made by David Brewer, a Scottish inventor in 1844. In 1922 first 3D film was made in black and white. 3D colour film was made in 1935. The reason for their interest was obvious as today we see that 3D image is very realistic and it brings 2D image to life. The people watching 3D feel to be part of the visuals coming from the TV.
To make 3D TV without glasses, the companies have gotten breakthrough, in recent years by developing a technology known as lenticular technology or parallax barrier. These methods of making 3D TV without glasses are also called as Auto stereoscopy. LG, one of the most advanced companies in electronics products, has been working on two new technologies. A Hungarian technology firm is also working on a project to develop 3D TV Box, which they say will deliver the images on 3D TV without glasses. Researchers from Korea are also trying to develop a solution that will use the minute prisms on an OLED display. OLED stands for Organic Light Emitting Diode. Japanese company Toshiba had launched 02 model 3D TV without glasses in 2010, which were quite good except for some drawbacks. One of their drawbacks was high price. The other one was that you had to sit close to the screen to get 3D effect. Companies have been working very hard to get rid of these drawbacks. But it is a matter of fact that this technology is very expensive to buy.
