3-D TV: The FAQ You Need to Know
3-D movies have been around since the 1950's. Granted, they are WAY better today but even in the 1950's they were fairly awesome for the time. Some movies are better in 3-D, some others seem to be marginally better.
Coming out this summer, consumers will see the first 3-D TV's. There are some pluses but like many new technologies, some insanity also.
The new 3-D TVs will require Active glasses for the viewer to wear. The anaglyphic glasses, those of red and blue and made popular in the 50's and 60's, will not work with 3-D TV. The glasses you wear for today's 3-D movies are passive where the polarization splits the image. These glasses are fine for movies but will not work well with 3-D TV. Manufacturers will require you to buy a pair of active glasses (around $70). These special glasses allow light to only reach one eye at a time, so, as you watch one side of the image begins to flash, then the other on the screen. The 3-D effect is good.
Keep in mind that 3-D TV is in its infancy, like color TV was in 1960-65, when there were only a few programs made and broadcast in color. Thus, most of the shows you will watch will not be in 3-D. It will be many years until all broadcasting is 3-D, if ever. BTW, it was not until 1966-67 that all programming and shows were finally broadcasted in color. It was a very big deal then. That's when every one bought their first color TV for $500.
What You Need
To take the 3-D TV plunge this summer, you need a 3-D TV and 3-D blu ray disc player. You need a TV with a screen refresh rate of at least 200 Hz for a good effect and a infrared transmitter to tell the active galsses when to polarize for the 3-D effect. If you have no blu-ray player, you will need a digital tuner to bring the limited broadcasts to your TV. Note: TV's with a refresh rate of 120Hz work fine also, but, you hace compatibility issues to get all the elements to work together.
Cuanto es? You will pay around $4000 for the 3-D TV package. The key players are hoping that by 2013, 3-D TV will be in 50% of the homes and by 2015, 75%. Right now, only ESPN and Discovery channels will offer some sporadic 3-D TV. The manufacturer's are also hoping that by 2020, wearing glasses to see 3-D TV will be a thing of the past.
