Are you searching for a new 3-dimensional TV? There are several 3-Dimension TV models in the market. See Panasonic TC-P50GT25 review. Before you go ahead and pick a 3D television from the shop read how the 3D operates and how it makes 3 dimension images.


How 3D TV Operates?
In a 3D TV Cheap Thaddeus Young Jersey , each eye is shown the scene taken from slightly dissimilar angles. When the head merges these different scenes it will seem three-dimensional. The 3-dimension TV technology needs different video camera to shoot the object and unique presentation technology on the TV.


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


Passive Eyeglasses:
The older Anaglyph passive eyeglasses have 2 dissimilar color lenses (red lens and blue) to filter out the pictures on the television screen. The 3D television will show two pictures one with reddish shade and another blue slightly offset from one other. When someone views the 3-dimension TV through the anaglyph eyeglasses the blue lens draws all the blue color from the television and hence will not let you to see the blue tinted images on the projection screen. Since each eye sees a different angle of the same scene the brain produces 3D effect.
Modern passive spectacles employ poliarized spectacles that function on the same principle we mentioned above. Rather than utilising two sets of pictures with dissimilar colours, the polarisation technique modifies the waves of light the spectator sees.
Nonetheless passive eyeglasses have some problems. First the use of anaglyph glasses will handicap us from seeing accurate colors of the scenes. The polarized eyeglasses on the other hand need you to coat your television presentation screen with an unique polarizing film as well.


Active Glasses :
Active specs as the name indicates got a very engaging part in viewing the 3-dimension video and requires power source connected to it. The active glass alternately opens and blocks the view of each lens to show each eye a different image at any time. This means that the 3-dimension specs need to be synchronized with the 3-dimension television display. This type of 3D spectacles employs LCD lenses to control the view of each eye and utilizes infra-red technology for synchronising.
Active 3D specs don’t hinder the video display of colours and therefore offers good image quality.
However they got some disadvantages as well. Unlike in case of passive 3D eyeglasses, the 3-dimension TV that employs active glasses will exhibit only one set of image on the screen at a time and will alternate the scenes shown to each eye at half of the number of frames. For example with 30 frames per second each eye will see only 15 frames of pictures each. This will in effect reduce the number of frames per second into half and will adversely affect the smooth movement of the video particularly in fast action video recordings such as sports.
