Are You Purchasing a 3-Dimension Television?
How many of you are looking for a new 3D television? There are different 3-Dimension TV models in the market. See Toshiba 55WX800U. Before you go ahead and choose a 3D television from the store find out how the 3-dimension television works and how it creates 3-dimensional pictures.
How 3D Television Works?
In case of 3D Television, each eye is presented the image filmed from slightly different angles. When your brain combines these slightly different images it will seem 3-dimensional. The 3-dimension TV video demands different television camera to film the object and also special presentation technology on the tv.
There are mainly two 3-dimension glass types. Active eyeglasses and Passive glasses.
Passive Spectacles:
The old Anaglyph passive glasses got 2 different color lenses (red and blue lens) to filter out the visuals on the TV screen. The 3D TV will show 2 pictures one with red touch and other blue tint slightly offset from one other. When a person view the 3D television through this type of spectacles the blue lens absorbs all the blue light from the television and thus will not allow you to see the bluish pictures on the projection screen. Becasue each eye sees a different angle of the same shot the brain creates 3D image.
Latest passive glasses utilize poliarized glasses which work on the same principle we mentioned earlier. Rather than utilising 2 sets of figures with contrary colors, the polarization technique alters the waves of light the viewer watches.
Nevertheless passive spectacles have certain disadvantages. First the use of anaglyph eyeglasses will hinder us from viewing true colors of the images. The polarized spectacles on the other hand require you to coat your TV display screen with an unique polarizing film first.
Active Spectacles :
Active glasses as the name suggests have a real active part in seeing the 3D video and demands power source associated to it. The active spectacles alternately opens and closes the view of each lens to show each eye a different picture at any time. This signifies that the 3D glasses require to be synced with the 3D TV display. This type of 3-dimension specs utlizes LCD lenses to control the view of each eye and uses infra red technology for synchronization.
Active 3D glasses don’t handicap the display of colors and hence provides superior picture quality.
Nonetheless they do have certain disadvantages. Unlike in case of passive 3D spectacles, the 3D Television that applies active eyeglasses will display only one set of picture on the screen at a time and will alternate the images 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 images each. This will effectively cut the number of frames per second into half and will affect the smooth movement of the picture specially in rapid action video recordings such as sports.
