Commonly asked questions about 3D TV’s
Various people have been talking about new 3D TV’s lately. There’s 3D movies at the theater like Avatar and they want to be able to watch 3D at home on their television. In this article were going to go over the basics on how 3D TV works!
With all the buzz around 3D televisions. There comes a lot of rumors and misconceptions. In this post we’ll provide the information that will clear some things up once and for all. First off you will need 3D glasses if you want to watch 3D Television, but not to many people are very thrilled about this, but it’s a minor price to pay for having 3D cinema in your living room. Plus many… if not all 3D televisions have the standard TV format (2D). 3D television can be turned on and off at the viewers will.
Currently there is not a lot of 3D content available, but 3D TV’s also give you a great picture with everything you watch even non 3D stuff too. So if you’re going to buy television. You may want to think of 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.
Another cool thing about 3D TV is that there are converters that turn your existing 2D media into 3D. Currently there isn’t very many 3D DVD collections out there, however you can breathe new life to your previous DVD or Blue Ray collection by converting them to 3D. Some 3D televisions like the Sony XBR52HX909 are going to have installed converters so you can view 3D TV right out of the box.
3D movies are actually filmed using 2 cameras to simulate what we see with both of our eyes. Our brain combines these two perspectives and that creates the 3D effect. What’s tricky is making sure you have the right perspective for each eye. Different TV companies are using somewhat different approaches. Most use special screens that can show two different vareities of an image at the same time. This is able to work by the screens image switching back and forth very quickly. The left eye and the right eye are shown two different images. If you’re watching 3D TV without the special 3d glasses then the image is going to look very blurry. If you have seen a 3D movie in the movie theater your probably familiar with the 3D glasses. The 3D glasses for TV’s are completely different. They are more complex. These are wireless, battery powered, liquid crystal, shutter glasses. 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. You wont notice any flashing back and forth, because this all happens over 240 times a second.
Beleive or not are minds are wired for 3D, That’s how the world views us. Our brains interpret the two images from a 3D TV screen in the same way it does with our two eyes in everyday life. One generally asked question is… Do the glasses create any flicker? No. The images change once every 1/100 of a second. So our brain just fills it in automatically.
3D TV has came and gone throughout history, remember virtual boy? Because of this people are uncertain about the success of 3D anything. It has a lot of challenges to over come in the living room. One thing is the ambient light reducing the 3D effect.
So with the pros and cons weighed out and the 3D Television 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.
