3D TV Technology

The word technology is being used too often in this decade as it has created a great impact in the way we think and function. We talk about things like computers, gaming and household appliances all the time. There are entertainment applications, as well as convenience and luxury applications of technology. In older days, cinema was a very popular way to relax and it was just as easy as buying a ticket and watching it. It has been about grabbing a tub of popcorn, some drinks and just enjoying the movie. The feeling one gets in a cinema theatre could never be compared to your Television Sets. How could we guess that this could actually change? The technology that we’re talking about is the 3D TV Technology.

This technology has a long history; back in the year 1844 a Scottish inventor started this journey of 3D TV by marking the first step which was the invention of the Stereoscope. It was first of its kind that would enable a camera to take pictures in 3-Dimensional form. Later on in the year 1855 the Kinematoscope was invented which helped movie makers and gave them the freedom to make movies in 3D. This marked the beginning of the 3D TV Technology.

There are in all three ways by which 3D Technology can project Stereoscopic images to the viewer and they are as follows:

* Anaglyphic 3D: one can view 3D images with the help of 2 color glasses. The colors on these 3D glasses are meant to be chromatically opposite and this is the reason why they are only red and cyan. These images are made with two colored layers. Although they are superimposed but in order to produce the depth effect the images are offset.

* Polarization 3D: One can view 3D images with the help of Polarized 3D glasses. In such televisions there are two types of images broadcasted one meant for each eye. The glasses contain a polarized filter which helps in sending the image which is meant for that specific eye.

* Alternate frame sequencing: In this form the rate at which the frames are shown is doubled which means the image that is shown in this television is 48 frames per second. The shutter LCD glasses contain a radio receiver on it which is in control of the transmitter located on the projector thus informing the shutter glasses which eye is meant to be open. This is the latest in 3D TV Technology.
