Are you searching for a new 3D TV? There are several 3D TV models in the bazaar. You may have seen lot of ads on the new 3D Television models. How precisely these televisions work and what are the factors you must recognize? Take a look at this guide to learn more about 3D TV and its working principle. Before you go and pick a 3-dimension tv from the shop find out how the 3D works and how it produces 3-dimensional pictures.
Type of 3-Dimension Television
Plasma 3-Dimension Television: Nowadays this sort of 3-Dimension Television performs superior as plasma creates illumination and the refresh rates of advanced plasma TV models are a lot higher. Look at Panasonic TC-P50GT25 review here.
LCD 3D Television: LCD TV models also have their 3D Television versions nowadays. Check Toshiba 55WX800U for LED 3-Dimension Television.
How 3D TV Works?
In case of 3-dimension Television, each eye is shown the same scene taken from slightly different angles. When the head merges these slightly different angle scenes it will appear 3-dimensional. The 3D tv image needs different video camera to film the scene and also special presentation technology on the TV.
One can find primarily two 3-dimension glass types. Active glasses and Passive 3d glasses.
Passive Eyeglasses:
The older Anaglyph passive eyeglasses have two dissimilar color lenses (red and blue lens) to filter the pictures on the television display screen. The 3-dimension TV will display two pictures one with red shade and other blue slightly offset from one other. When someone views the 3-dimension TV through the anaglyph spectacles the blue color lens draws all the blue color from the television and as a result will not let you to see the blue images on the projection screen. Since each eye sees a different angle of the same image the brain creates 3D image.
Modern passive glasses employ poliarized glasses that function on the same principle we mentioned earlier. Instead of using two sets of pictures with contrary colors, the polarisation technique modifies the waves of light the viewer watches. Nonetheless passive eyeglasses have certain disadvantages. First the use of anaglyph spectacles will obstruct us from viewing right colours of the scenes. The polarized spectacles on the other hand require you to coat your television display screen with a special polarizing film first.
Active Spectacles :
Active glasses as the name suggests have a really active part in seeing the 3D picture and needs power source connected to it. The active glass alternately opens and closes the view of each lens to show each eye a different picture at any time. This signifies that the 3-dimension eyeglasses require to be synced with the 3D TV display. This kind of 3D eyeglasses makes use of LCD lenses to control the view of each eye and employs infra red technology for synchronising.
Active 3D eyeglasses don’t hinder the video display of colours and thus provides good image quality. Nonetheless they do have some disadvantages. Unlike in case of passive 3D specs, the 3D TV that utilizes active spectacles will exhibit only one set of picture on the screen at a time and will rotate the pictures showed to each eye at half of the number of frames. For example with 30 frames per second each eye will see only fifteen frames of images each. This will effectively cut the number of frames per second into half and will affect the smooth motion of the picture specially in fast action video recordings including sports.
