Like most other manufacturers they offer active shutter based 3D TV where the glasses used control what each eye sees by opening and closing and also have a Cinema 3D option.
LG’s Cinema 3D TVs unlike other 3D TVs uses the same technology that you will find in a cinema. This uses a polarised method, which makes the technology a lot cheaper, especially the cost of the glasses.
There are other advantages from this polarised method, including the fact that you can sit where you want in relation to your TV, at least to the same extent that you can with a 2D TV.
You also don’t have to worry about the risk of interference to the glasses as with Active Shutter glasses that have to communicate with the TV set via infra-red. This can stop working where batteries are going flat, if you sit too far away, if there is to much light in a room and if you turn your head away from the TV.
Many people also prefer the feel of the much lighter polarized glasses, which you can use with your head on its side as well if you want to lie down to watch TV.
In contrast to LG’s active shutter TVs though, they generally come with two pairs of glasses. The glasses cost around £100 each, the polarised glasses a couple of pounds.
LG have tried to take slices at either ends of the market and even within their active shutter range they have had a bigger range than most other manufacturers with both fully featured TVs and those with simpler features at a lower cost.
For full HD though active shutter is the only option, the polarized version can’t provide full 1080 p as only half the lines go to each eye meaning that each eye sees 50% as many lines as if you watch the same TV in 2D.
It may well be that if you are looking for a 3D TV to tide you over until auto 3D TVs become available, and available so that you don’t have to remain glued to one position, then the cheaper polarizing style 3D TVs will be a better option and will mean you waste less money, but if you are a fan of HD you may notice the difference.
The polarising 3D TVS have been popular in pubs and other public venues where glasses cost only around a £1 or 2 per pair and these LG TVs were the ones used in a partnership with BskyB in the UK for the first ever 3D broadcasts to a selection of British Pubs.
LGs partnership with Sky has also included joint marketing and SKY TV recommending LG 3D TVs and a cashback offer of £400 being available to Sky customers buying LG 3D TVs.
