3D TVs and How They Work
3D Movies and now TV channels have become increasingly popular in recent years and in order to make the most of this new technology you will need to have a special type of television. These TVs need to have certain specifications to be classed as “3D ready” and whilst high definition relates to how sharp the image is, the key statistic to do with whether a TV is capable of producing 3D images is the speed of your TV.
3D Movies and now TV channels have become increasingly popular in recent years and in order to make the most of this new technology you will need to have a special type of television. These TVs need to have certain specifications to be classed as “3D ready” and whilst high definition relates to how sharp the image is, the key statistic to do with whether a TV is capable of producing 3D images is the speed of your TV.
In order to understand how a 3D TV works we need to understand how our own vision works in perceiving depth and things in three dimensions, this is done thanks to our two eyes being spaced slightly apart, the left eye sees the world at a slightly different angle to the right eye. It is the combination of the two ‘images’ that makes us see the world in 3D. When you watch a standard TV you are going to see the picture from one eye, the camera.
So with a 3D TV you are going to need two images to be shown at once, much like how our eyes work. Watching this with the naked eye is going to look strange and not produce the right effect, which is why 3D TVs come with sets of specialist glasses. These glasses are known as active shutter glasses, where each lens acts as a shutter on each eye allowing the image to be displayed correctly, as the left and right eye images are produced on the screen these glasses and their shutter process are able to sync up to produce a sharp and colourful 3D effect – miles better than the red and blue 3D glasses from the past.
The only problem with these TVs is you have to wear the active shutter glasses whenever you want to watch a 3D movie or TV show, these glasses require batteries and so can run out in the middle of a movie which can be a bit of a pain. Also TVs tend to come with a limited amount of these glasses usually 2-4 sets meaning that it can be difficult when you have guests or a family larger than 4 people who want to watch at any particular time.
These TV sets obviously have their fans as well as detractors but as a growing technology more and more TV manufacturers are making sure their TV sets come 3D ready meaning that if you are in the market for a new television then a 3D set may end up being your choice even if you don’t plan to use the technology itself.
There are many 3D TVs now available from some of the leading names in TV technology such as Sony 3D TVs and Panasonic 3D sets as well.
