By: Eichner Odonal


Lots of individuals have been chatting about 3D lately. With fresh 3D movies out like Avatar, there is a renewed demand for 3D TV's in the home. In this article we'll be covering the commonly ask questions and the FAQ's of 3D TV!

With all the noise around 3D TV's. There comes a lot of facts and rumors. In this post we'll provide the information that will clear some things up once and for all. First thing you will need 3D glasses if you want to view 3D TV, however not to many individuals are tickled to death about this, but it's a small price to pay for having a 3D movie theater in your home. Plus a lot of... if not all 3D televisions have the standard TV format. 3D TV can be switched on and off at the user's will.

Currently their is alot of 3D software out there like dvd's, but 3D TV's also give you a great picture even on non-3D stuff too. So if you're going to buy tv. You may want to consider a new 3D TV. You'll get a great picture now and will be ready in the near future when more 3D content is available.

A great thing about 3D televisions is that some of your previous 2D collections can be watched in 3D. Currently there might not be very many 3D DVD collections out on the market, however you can bring new life to your old Blue Ray or DVD collection by converting them to 3D. Some 3D televisions like the Sony XBR52HX909 are going to have built in converters so you can view 3D TV right out of the box.

3D movies are shot in a different way. They use two different cameras, one for each eye. Our brain automatically combines these 2 moving images to give that 3D look. What's tricky is making sure you have the right perspective for each eye. Different TV manufactures are using different methods of achieving 3D. The greater part of 3D TV's use a special screen that displays two different versions of an image at the same time. This is able to work by the screens image switching back and forth very rapidly. So the right eye and the left eye are shown two different versions. If your watching 3D television without the special 3D glasses you will see a very blurry image. If you've seen movies like Avatar recently then your probably familiar with the 3D glasses. However the 3D glasses for televisions are completely different. They are more complex. These are special type of battery powered shutter glasses with liquid crystals. I know that may scare you, but it's really not complicated. The 3D TV sends out infer red signals to control the timing of the glasses. So either the left or the right image that darkens and blacks out the image in sync with what's on the TV screen. So your left and right eye see both the left and right version at the same time.

Beleive or not are minds are pre-programed for 3D, That's how the world views us. Our brains translate what's on a 3D TV screen in the same fashion as everyday life. One frequently asked question is... Does the glasses create a flash? The answer to that is no. The images flash over hundred times a second. So our minds just fill in the blanks automatically.

3D television has appeared and disappeared many times throughout history, I bet you remember the virtual boy? Because of this people are uncertain about the success of 3D anything. 3D TV has a lot of challenges to over come in the home. One thing is the ambient light reducing the 3D effect.

So with the pros and cons weighed out and the 3D TV experience being so fresh on the market. It's hard to make a decision. It seems the industry is looking for pioneers to grasp the reigns of 3D tv and brag to all the neighbors about how cool your new TV is. The only down side is the glasses. However keep in mind that normal 2D television can be watched at anytime where glasses aren't needed. So that problem is solved.
