Whether or not you find the idea of owning a 3D TV an attractive proposition, 3DTV is here to stay whether you like it or not. Over the next 3 years it is predicted that 50 percent of all TVs sold globally will be 3D compatible, with the major manufacturers incorporating this technology into their TVs as standard. So if you are currently looking to purchase a new television now or expect to replace your aging TV over the next few years, then it can do no harm about knowing a little about the subject.
Samsung, one of the leading producers has gone down the path of utilizing what is known as active shutter 3D TV glasses in their range of Samsung 3D TVs. This involves the viewer wearing a pair of 3D glasses that are synchronized with the television. The lenses in these glasses are alternately blocked out so that viewer is shown a separate set of images for each eye. This happens hundreds of times a second, so fast that the eyes do not detect any flickering. The method of showing each eye a different image tricks the viewer’s brain into interpreting the images being shown as one 3D image.LG another of the big players in 3D TV offers a different method of implementing 3D TV. It is called passive 3D technology. This method uses similar methods that you may have experienced in the cinema to produce 3D images and still requires the user wears a pair of specs. However they are passive 3D glasses, which are responsible for all the advantages that relate to this method of producing 3D TV. By far the biggest benefit of passive 3D TV is that the 3D glasses are very cheap, costing less than $10 a pair. When you consider that a pair of active shutter glasses costs anywhere from $70 up to $150 depending on the style and brand you choose, then this soon becomes an attractive selling point especially if you potentially have a big audience at home. Because of their low cost, LG TVs are shipped with seven pairs of 3D glasses whilst a Samsung 3D TV normally only comes with two. Another benefit of passive 3D glasses is that they are more comfortable to wear than active shutter 3D glasses. This is because active glasses contain shutters, circuitry and batteries to make them work whereas passive glasses are no different than wearing a pair of normal shades.
As well as being physically comfortable to wear, watching a passive TV can also be less of a strain on the viewer’s eyes. Some viewers have stated that after prolonged usage they experience eye fatigue and sometime headaches, a side effect from the constant flickering of the glasses that must be worn. Passive 3D TV can be better understood when you understand a little bit more of how this technology works. Where by active technology uses two sets of alternating images, passive 3D TV only uses one single on-screen image which has all of the visual elements that the passive 3D glasses filter out to the viewers left and right eyes, there is no rapid filtering going on here. The last benefit of passive 3D glasses is that they don’t reduce the brightness of the pictures on display as much as active 3D glasses do. This is because active shutters are in effect blocking the light to one eye at anyone time, where as passive glasses just filtering some of the light to both eyes at once.Passive sounds good up to now, but what are the negatives of passive 3D TV? Well, whereby active 3D TV uses two alternating HD images (one for each eye), because passive 3D TV displays a single image some of which is filtered out for each eye, then the effective resolution of the passive 3D TV is lower than active 3D. This is not just a technical figure, is real and noticeable when viewing. However the effective resolution is still 60-70% of HD and so is still impressive. Also another characteristic of passive 3D means that the wider the angle you view the TV from, the lesser the depth of the 3D effects.In summary what does all this mean? Well generally speaking passive 3D TV produces brighter images and when well implemented 3D images with seemingly greater depth than active 3D. Active 3D TV produces pictures of a higher resolution and can be viewed from wider angles. If money is not your primary concern when choosing your next 3DTV, then get down to your local TV showroom and ask for a demonstration of a passive LG 3D TV. The LG LW6500 or LW650 are examples of such models. Compare them to an active 3D TV such as any Samsung 3D TV, and decide your preference. If the price tag is a big deciding factor in your choice as is for a lot of consumers, then an LG 3D TV is definitely an attractive choice.
