Microsoft applied sciences group has developed a new lens to be used in television screens which facilitates viewing three dimensional videos without wearing glasses. The 3D fever has gripped the world after the release of the super hit James Cameron’s movie Avtaar last year. This technology is getting popular day by day.

So what exactly is 3D? 3D technology is a type of technology used for viewing a program into a three dimensional realistic field. It should also have the techniques of 3D presentation such as multi view capture, stereoscopic capture and a 3D display. A basic preface is required in order to understand the working of a 3D display is how your eyes are working.

For example, look at the mouse of your computer or anything else nearby. There are two separate lenses in nutshell for your left eye and right eye taking two different angled images which are sent to your brain. Then the brain acts as a image processor and a three dimensional picture is formed in your mind. The same principle is applicable with a 3D display.

Going by its present state, this glittering technology has its down side as well. To be become a reality and make it to the homes of the masses, 3D technology has a long way to go. It has to sort out some important issues before it can think of becoming the mainstream technology.

As of now this is a new technology and for an average family is quite expensive. The lack of availability of 3D content and the hindrance caused by wearing 3D glasses may make TV watching less impressive than going out and watching in the theatres.

This development can revolutionize the experience of 3D viewing as well as research by various technological firms in order to promote san pesky glasses for 3D display. The lens is made thin from the bottom as compared to its top. It is about 11 millimeters from top and about 6 millimeters from bottom. The light enters the viewers eye by switching its bottom edge on and off along with light-emitting diodes. This phenomenon creates a stereoscopic 3D effect when coupled with light.

With the help of this phenomenon the viewer is able to see the images in 3D effect. The lens helps in controlling the direction of light. The 3D display has a camera which can track the viewers which enable to steer light towards them.

This type of display can deliver 3D video to two viewers at a time (one video for each individual eye) regardless of where they are placed. It has the capability of viewing ordinary 2D video for 4 people at a time (one video for each individual).
