3D TV

I went to visit a customer for work this week, and  they were working parts for a 3D television. He gave a strong endorsement for 3D TV saying they worked very well.

Intrigued, I went to Best Buy, and checked out the Panasonic set ($2250), and it was cool. The illusion was outstanding -- much better than the theater. It was clearer, gave a greater sensation of space, and could extend into the room farther.

The technology of TV 3D is based on the glasses. The glasses have LCD lenses that blink at 120 cycles per second. This is called alternate-frame sequencing. They black out one eye then the other eye.  The TV shifts back and forth from right eye to left eye images at 120 times per second (Hz.) The TV needs capable of refreshing fast enough to keep up with the 120 Hz switch rate. The TV signals to the glasses by IR or radio them synchronized to the TV.

The problem with 3D TV today is no content. The only way to get programing is to buy a 3D enabled Blu-Ray player, and even then there are only a few movies available.

3D TV proponents are saying gaming will be revolutionized, and I don't doubt it.
