New technology in 3D has made huge improvements over the earlier 3D movies. Before rushing out to buy a 3D TV, check out some basic information about the TV before going.
Within the next 9 years, 3D is going to boom. You thought Tube, HDTV, LCD, and Plasma was an explosion. Some think the 3D would be more expensive, but it won't. The cost will be slightly higher just starting out, but within a year, the price will come down to the current.
How does 3D work?
3D has been around since 1840 - can you believe it. Charles Wheatstone call it the stereoscope. The camera that records the video uses two lenses that are slightly offset about the same distance as the human eye. The camera takes two separate images just like our eyes see two different images. Using special glasses your eyes can be tricked in to seeing a 3-Dimensional image on a flat surface.
There are 2 main categories:
1. Active Shutter Glasses
2. Polarized Glasses
Active Shutter Glasses use a sensor that connects to the TV and emits a signal to the glasses telling it to open or close one eye or the other. at the exact time the proper image is displayed for that eye.
Polarized Glasses allow you to see two pictures at one time with different colors. The movie theater actually plays two movie reels at the same time resulting in the 3D effect.
If you want to get in on the action and I do mean action. Check out these great 3D TVs that won't put a dent in your wallet.
