We spent the much in the last decade talking about Plasma Television set, LCD Television set, and HDTVs but those discussions are fast getting close to their expiry date. The second decade in the second millennium will be all about the 3-D Tv.
In 1844 a man from the name of David Brewster invented stereoscope - that was the delivery of 3D imagery as we be aware of it. However today's world have all but removed interest in the format as content was scarce and the colored glasses needed to like the 3-D experience became more of a problem than the usual useful tool. That is until today, and also the recent technological advancements made from the top Tv set manufacturers to bring true 3-D Television watching experience in the middle of your lounge.
To understand how 3D Tv technology works, one must know the way our eyes work. Our eyes are several centimeters aside from each other and for that reason get the input picture from different perspectives. Tricking the brain in this manner is not any straightforward job, and for years the simple and cheap technology was utilizing colored glasses that had the large problem with limiting the number of colors that you could like a film in. Panasonic is one of the manufactures that has created a auto stereoscope method that has the capacity to make 3D viewing possible without the need of glasses in any way.
Despite the forthcoming launches of 3D channels by Sky (in the United kingdom) and Directv (in the USA) in 2010, both of which say that 3D content could be delivered through their existing HD set top boxes, there still won't be much 3D content for them to transmit. An extra huge hurdle is that everyone wanting to watch the 3DTV content will need a pair of special 3D glasses.
The glasses are required to view the 3D effect, although 3DTV's will perform properly well as regular 2D screens for the time you're watching 2D content. The 3D glasses required for the new 3-D TV's are what's known as "active shutter" which means they synchronise with the Television set to show images alternatively to the left eye then the right eye.
While one eye sees an picture, the additional eye sees nothing as that side from the glasses is darkened. Your brain stitches the switching images into a coherent 3D image.
Naturally, you will need more than one pair of glasses if there's several person inside your household. The graphic card manufacturer, nVidia, is already offering glasses and software which changes nearly every 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 give each eye a flicker-free view from the action. Most people's computers and monitors won't be good enough, but avid gamers will be quick to upgrade once they see the impressive 3D effects and also the added immersion 3D brings to game play.
