Just when you thought you’d got your head around the latest HD technology, along comes 3D televisions. They seemed a bit of a novelty item at first but are becoming more and more popular and the makers are getting extremely competitive.
Unfortunately it is not yet possible to have a 3D TV experience without the glasses but this seems a small inconvenience to those who have enjoyed a film or sporting event in 3D. 3D TV’s superimpose two separate images onto the screen which are then viewed through glasses which merge them as one. Old glasses were classed as passive while the new models use active technology. The glasses work by blocking each eye quickly and in sequence, so the user sees one image with the left eye and another for the right, generating the 3D images.
Enough of the technology though. Many films are now filmed in 3D and are being broadcast by Sky while there is already a range of sport available – football, golf and darts – and this is set to expand. The next area to experience 3D is likely to be gaming. If you’re not a particular film or sports fan though, it’s probably not worth investing in a 3D TV just yet. They are likely to come down in price as the type of content broadens.
But if you want to experience all that 3D can offer, you will need a 3D ready TV, as well as a 3D Blu-ray player or PS3 and a subscription to 3D TV content. There’s still a long way to go but it’s an exciting time in 3D technology and new advances are being made all the time.
