3D Television Set Technology

To comprehend how 3D Television set technology works, one must know how our eyes work. Our eyes are several centimeters apart from each additional and so obtain the input picture from different perspectives. Our brain uses that information and it is smart enough to mesh the two into one single view, making depth, and making what we see 3 dimensional. Tricking the brain in this manner is not any straightforward process, and for years the simple and cheap technology was making use of colored glasses that had the large problem with limiting the number of colors that you could enjoy a movie in. Panasonic is one from the manufactures that has created a auto stereoscope method that has the capacity to make 3D watching doable with no need of glasses whatsoever. One big hurdle with obtaining people to upgrade their televisions to 3D is that there's not a lot of viewable content at the moment.
A second large hurdle is that everyone wanting to watch the 3DTV content will need a pair of special 3D glasses. The glasses have to view the 3D effect, although 3DTV's will function perfectly well as standard 2D screens for the time you're watching 2D content. For that upcoming 3DTV's we're not talking cheap, disposable red/blue glasses, either.
The 3D glasses required for the new 3-D TV's are what's known as "active shutter" which means they synchronise with the Telly showing images alternatively towards the left eye then the right eye. While one eye sees an picture, the other eye sees nothing as that side of the glasses is darkened. Your brain stitches the switching images into a coherent 3D image.
Of course, you'll need more than one pair of glasses if there's more than one person inside your household.
The graphic card manufacturer, nVidia, is already offering glasses and software which changes almost any computer game into a 3D version, as long as you have a graphics card with enough power and a screen which can refresh at 120Hz, enough to provide each eye a flicker-free view in the action. Most people's computers and monitors won't be adequate, but avid gamers is going to be quick to upgrade once they see the impressive 3D effects and the added immersion 3D gives game play.
