While it's a thrilling experience to watch 3D movies on big screen in theatres, the best 3D TVs grant you the same experience at home. To capture this 3D experience through your eyes, 3D glasses are a must in a theatre or at home. Along with a 3D TV and 3D glasses, you must have a good quality source that sends 3D video content for you to watch it on your TV. Depending on the flat panel type used and the display size of your TV, the qualitative 3D viewing experience varies. With an ample screen size, choose a flat panel of your choice among the available types which are LED, LCD and Plasma. Having a big HD screen means a greater feeling of depth you while watching your 3D.
A normal flat panel HDTV could also be called a 2D TV because the display on which you watch the video content is along two dimensions: height and width. However, in a best 3D HDTV you could watch the same content (if it's 3D content) along three dimensions: height, width and depth.
Working: On the best 3D TV's, the 3D content displayed actually contains two separate images of the same scene: one for the left eye and the other for the right eye. In fact, you cannot notice this unless you are watching the TV with the 3D glasses on. This is because the combined image can only be seen when you watch the scene with 3D glasses, which virtually give you the feeling of depth of the scene. Remember, the depth may be inward or outward and that depends on the premises of the scene you are watching.
The 3D content you see on a TV might be from a channel that broadcasts 3D TV programs, 3D movies, or games read from blu ray players (compatible with HDMI 1.4). 3D TV's are just 2D TV's, having an extra dimension - depth. Hence, if you buy a 3D TV you could switch between the 2D and 3D modes. Some of the TV brands in the market also offer you the feature of conversion from 2D to 3D. A straight 3D video content from the source which is displayed on your TV is called native 3D, and that is preferred the most, because of the high quality it offers when compared to the lower quality content which is converted from 2D.(Some of the TV brands in the market also offer an option of converting 2D content to 3D. However the quality of converted 3D can't really compare with native 3D content even on a good 3D HDTV. Native 3D is pure 3D content from the source itself, which is then displayed by your 3D TV and is consequently of much higher quality.)
Types of 3D: Active 3D and Passive 3D are currently the two 3D TV types available in the market. The difference between these two is marked by the type of 3D glasses used to watch your 3D TV. You need Active 3D glasses and Passive 3D glasses to watch 3D content on only Active and Passive 3D TV's respectively. Passive 3D glasses are most common in 3D theatres because of their flexible and comfortable usability properties. Active and Passive 3D TV technologies have their own set of advantages and drawbacks, hence you might have to choose them precisely.
Active glasses work on batteries and use liquid crystal shutters while passive glasses use simple and inexpensive polarizing lenses.
The advantage of Active 3D glasses is that they work well with extreme viewing angles. And Active 3D glasses allow you to view full HD resolution whereas Passive 3D glasses support a resolution of just half the resolution of the same content watched in 2D. Passive 3D glasses are lighter and cheaper, wearing and using them are easier. Also, they support brighter 3D image than Active 3D glasses, infact you could see comparatively dimmer pictures through Active 3D glasses. Passive 3D glasses won't work on Plasma TV's while Active 3D glasses work on LCD, LED and Plasma TV's.
