3D

 

Very simply, the televisions sold by Electronic World that have 3D technology allow you to view 3-dimensional images on screen. By viewing something in 3D the images really come to life, giving depth to what you are watching and making you feel part of the action. Chances are you have seen or been aware of 3D technology already; you can’t have failed to notice the floods of 3D movies at the cinema, or maybe you’ve even watched a 3D sporting event - well now 3D content is available for everyone to enjoy in their home.

How does 3D work?

3D works by superimposing two separate images onto the same screen and then you view those images through specially designed 3D glasses that basically allow you to view both images as one.

3D technology has been around for decades, the heyday being in the late 1980s and 1990s. Back then 3D viewing was made possible through ‘passive’ glasses (remember those white glass with red and green coloured lenses?)that contained polarized filters to restrict the amount of light that reaches each of the viewers’ eyes.

Why the modern day version of 3D technology is so exciting is that we now have ‘active’ technology in the glasses. Active technology uses active liquid crystal shutter glasses, which contain liquid crystals that can be made opaque and thus acting as a shutter for the eyes. Viewers are required to wear these glasses to watch 3D images because they quickly block each eye in sequence to ensure that each eye only sees the corresponding image being displayed on the 3D TV display screen. These glasses allow the viewers to watch one image for their left eye and another one for their right eye, which generates the most spectacular 3D images to date.

What kind of things are now using 3D technology?

More and more content is being released in 3D; movies are now commonly filmed in 3D which means firstly cinema visits for 3D movies and also 3D Blu-ray films. Sport is also being filmed in 3D with Sky allowing users to watch football, golf and even darts in 3D this year so far, with even more on the horizon.

The latest area to go 3D mad is the gaming world. We expect that by next year you will be able to play some of the leading games titles in 3D.

So how do I get 3D?

In order to watch 3D you will need a 3D ready television. Then you just have to choose what content you want to watch. For 3D films you can buy a 3D Blu-ray player or PS3, for sport and other TV content you will need to contact your TV service provider to ensure you are subscribed to 3D TV content. The only other addition you will need is the right connectivity; a standard HDMI cable such as you would use for a HD TV will not support 3D content so you will need to pick up a 1.4 HDMI cable which is compatible with 3D viewing. That’s it! With all the gear available now you have all you need to make your 3D dream a reality.
