Have you looked for a new TV lately? Well, if you have then you will have looked at 3D TVs. This year at the Consumer Electronic Show 2011, manufacturers were pushing hard for 3D TV. Here's what you need to know about it.

Samsung, Panasonic, LG, Visio, and other TV manufacturers  first introduced 3D TV at last year’s CES (2010). All the major TV manufacturers jumped on board and 3D TVs became almost immediately available. 3D movies starrted to appear. And 3D content for TV started to appear.

Although the public didn’t rush to purchase 3D televisions during 2010, manufacturers are continuing with their push to the world of 3D. Unfortunately, each manufacturer has their own way of implementing 3D, so the 3D glasses are not interchangeable meaning that if you have a Samsung 3D TV, you must have Samsung 3D glasses, etc. And this year, the situation with 3D glasses is starting to get even more complicated.

Several advocacy groups have recently started warning about eye-related problems caused by viewing 3D images. Many 3D televisions including those by Samsung, Sony, and Panasonic currently come with health warnings. Because of these health alerts, LG announced at the show that they will move from active shutter glasses to polarized glasses which will be cheaper and supposedly better for your eyes. That means that if you want to make an intelligent purchase of a 3D television, you will not only have to look at the quality of the image, but will also have to consider the type of glasses and the effect that they will have on your eyes.

You might think that all you have to do is wait for the technology to be good enough to project 3D videos that don’t require wearing glasses, but that won’t solve the problem either. Recently Nintendo issued a warning to parents to not let their children use their upcoming 3DS gaming device in 3D mode due to potential damage to developing eye -- and the Nintendo 3DS gaming device will not require any glasses.

At CES this year (2011), Toshiba was also showing off a new technology that allows you to view 3D images without glasses. I tried this out and was extremely disappointed. You had to be directly in front of the image to see it in 3D. Taking even a half a step to the side resulted in seeing double images. On top of that simply standing and watching this 3D television, made me dizzy.

I spoke to a Samsung representative who said that Samsung has lowered the premium cost on a 3D TV from $600 last year to only $200 this year. He said that because of this, Samsung expects 60% of their television sales in 2011 to be from 3D TVs. Samsung obviously believes that many people will be willing to pay an extra $200 to get 3D on their TV. That, however, is yet to be proven.

The bottom line is that the manufacturers will be pushing hard on 3D TVs this year, but it is really up to the consumer to accept or reject this technology. One side effect to this extreme push of a technology that is not quite ready for prime time may be one that the manufacturers haven’t accurately assessed. Many of us may just stand by the sidelines and not make a television purchase until this 3D thing shakes out.
