What You Need to Know About 3D Television

Are you looking for a new 3D TV? You can find different 3-Dimension TV brands in the marketplace. You might have seen lot of adverts about the latest 3D TV models. How exactly the 3D televisions work and what are the things you should recognize? Read this guide to learn more about 3D TV and its working principle. Before you go and choose a 3D television from the shop find out how the 3-dimension TV functions and how it makes 3-dimensional figures.

Type of 3-Dimension TVs

LCD 3D TV: Liquid crystal display television products also have their 3D TV versions now. See Toshiba 55WX800U review for LED 3-Dimension TV.

Plasma 3-Dimension TV: At the moment this kind of 3-Dimension TV performs superior as plasma creates illumination and the refresh rates of advanced plasma TV models are a lot superior. Look into Panasonic TC-P50GT25 review online.

How 3D TV Operates?
In a 3D TV, each eye is presented the scene filmed from slightly unlike angles. While your head combines these slightly different shots it will appear three-dimensional. The 3D television technology requires different camera to capture the scene and also special display technology on the television.

There are mainly two 3D glass types. Active 3D glasses and Passive 3d glasses.

Passive Glasses:
The older Anaglyph passive spectacles got 2 different color lenses (red lens and blue) to filter out the visuals on the television screen. The 3D television will display 2 pictures one with reddish shade and another blue tint slightly offset from each other. When someone views the 3D TV through the anaglyph glasses the blue color lens draws all the blue color from the TV and thus will not allow you to see the blue figures on the screen. Since each eye watches a different angle of the same image the head develops 3D effect.
Latest passive glasses apply poliarized glasses which work on the identical principle we mentioned above. Instead of employing 2 sets of figures with dissimilar colors, the polarization method alters the waves of light the spectator watches. Nonetheless passive glasses got some disadvantages. The anaglyph spectacles strain the color of the scene in video display. The polarized glasses on the other hand require you to coat your television display screen with a unique polarizing film as well.

Active Eyeglasses :
Active spectacles as the name suggests got a really active part in viewing the 3D picture and demands power source connected to it. The active spectacles alternately opens and closes the view of each lens to show each eye a different image at any time. This means that the 3D spectacles need to be synchronized with the 3D television display. This kind of 3D spectacles makes use of LCD lenses to control the view of each eye and employs infra-red technology for synchronization.
Active 3D spectacles dont handicap the video display of colors and therefore provides superior picture quality. Nonetheless they do have some disadvantages as well. Unlike in case of passive 3D spectacles, the 3D TV that employs active spectacles will show only one set of image on the screen at a time and will alternate the pictures showed to each eye at half of the number of frames. For example with thrity frames per second each eye will see only 15 frames of pictures each. This will in effect cut the number of frames per second into half and will affect the smooth motion of the picture particularly in rapid action videos including sporting activities.
