Learn about 3D TV technology

The television technology research is breaking the limits that was halted for over 2 decades.

From Black white discrete scene TVs to color TVs was a continuous evolvement which stopped in 80s and research got focused on create big screen flat TVs for commercial use.

Last ¾ years the flat screen TVs have seen their way in average consumers home

The industry is now back with another breakthrough with 3D TV.

This article is going to unveil secrets of the 3D technology.

The stereo pair images

Our eyes are about 2-3 inches apart. Each eye sees a slightly different image of the same scene and sends to the brain The brain combines the images together, filling the area between two images using information from depth of the objects.

So the concept for manufacturers of 3d TV is simple. They want to create brain like affect in TV so that your eyes send two spaced images from the TV to the brain and you could see 3D images inside the digital screen.

The 3D TV:

From Jan 7 through January 10, the major brands showcased their 3D TV technology in CES 2010 conference.

There are 4 kinds of TV that are in this category:

Passive Glass System: The classic system where the screen carries two images each spaces apart slightly and carrying opposite polarized signals. You wear red/blue or polarized set of glasses (similar to one you get at theme park theaters). Your brain helps putting together 3D affect of the image.

Active Glass System:These TVs are capable of converting any image to 3D image. The technology uses cyclic polarization where polarization alternates in sync with the refresh rate of the screen and without glasses your see two images that your brain puts together as 3d image

Lenticular viewing: These sets are designed such that those can be watched without wearing any glasses. The TV screen carries a special lense that sends two different set of signals to eyes. The catch is that you have to sit at a particular distance.

Glass Slab Style system: Another one featured on the conference was a TV whose screen was a few cm think. The front screen carrying the one image and back screen carrying other and thus allowing viewers brain to create 3d images

The recent hit of AVATAR movie shown in IMAX 3D experience theaters reflects the inclination of the people to embrace the technology. Currently it is expensive to create those TVs and so is for consumer. However like other technologies, the possibility of $500 46” 3D TV cannot be denied.

If you are keen on getting the one, then Panasonic could be best as they are pioneers who created this technology. If you are Sony or Samsung lover, then wait till they create the rock star versions of 3D tv in couple of years.

As always hope you had fun reading and gained some insights
