Whats 3D TV
Just like how the HD TVs first came out they were marked with a ‘HD Ready’ sticker. The new 3D TVs now have a similar sticker that says ’3D Ready’.
Now if you’re wondering what 3D Ready really means then the following guide should explain this to you in simple words.
Whats 3D Ready
The latest 3D enabled televisions include a 3D processor and emitter that deliver the 3D viewing experience. These TVs do have different set of capabilities for 3D such as half/full and HD resolution formats with Blue-ray 3D compatibility. In simple words if you are after a 3D TV then look for a Full 3D with HD capability, and the rest of the terms used around these are just marketing gimmicks that should not confuse you.
Screen size and refresh rate
3D TVs are now available in various screen sizes that you may choose according to your own suitability. These TVs have a minimum refresh rate of 120Hz which means the refresh rate for each eye is 60Hz. Higher refresh rate would mean you get a smoother 3D effect.
How much does it cost
Initially the 3D TVs were very expensive but now with more and more brands producing these televisions, there seems to be a growing competition for a better price and 3D TVs are not as expensive as you might think. You can find strating 3D TV prices for from £1000 for the basic models. The HD LED and LCD models may cost a little extra and all the way up to a few thousand pounds.
How 3D TV Technology works
All television sets are only capable of displaying 2D images, however a 3D TV creates separate 2D images for each eye, which then creates the illusion of 3 dimensions.
The illusion of a 3 dimensional image has been possible due to the fact that we have the ability to view different images from each one of our eyes, when we view something from a suitable distance and angle. Our brain then combines these separate images in to one, and create the illusion of a 3 dimensional image.
There are several different methods used to create 3 dimensional images, however we would like to discuss the most popular ones, read below.
3 dimensional images using 3D glasses
Method 1: In this method two images are combined into a single image, each image containing a slighly different angle and depth of the same scene. The different angles are altered by a colour quoting or filter. While you wear 3D glasses with two different coloured lenses, then each one of these coloured lenses block out one of the two combined images so you see the different dimensions of the same images with each eye.
Method 2: In this method powered 3D glasses with LCD lenses are uses. These glasses work just like the method described above but operate via infrared or blue-tooth to systematically deliver a complete version of the image to each eye to create the illusion.
3 dimensional images without glasses
This new method of delivering 3D images without the use of 3D glasses is becoming more popular than any other methods described above. In this method filters or lenses are placed in front of the TV screen to separate the images for each eye.
