All Kinds of Glass

Glass Open

Why do I need glasses for my 3d tv?

The answer is no. To be fair, there is a TV you can watch in 3D without glasses, but the cost is exorbitant and the quality poor. For the most part, you cannot register a 3D image on a 2D surface such as a TV without optical help.

 

History

Interestingly, the issue of 3D and glasses isn't new. 3D is a concept inventors have worked on for almost two centuries. And you can understand why. 3D brings a 2D image to life. You feel as though you're part of an exciting visual experience.

 

Back in 1844, for instance, a Scottish inventor, David Brewer, made a stereoscope. This optical device enabled viewers to see specially taken photos in 3D.

 

11 years later, a very basic stereo camera appeared – the Kinematoscope. The public had to wait until 1922, though, for the first 3D film. This was in black and white. The first film in 3D colour arrived in 1935.

 

Red and Green

3D films of the 1950s such as House of Wax were a great success. To view them you needed a pair of glasses that had a red and a green lens.

 

Cinemas often issued these glasses at the door. They usually had cardboard frames with plastic lenses. As you might expect, the standard of 3D was dubious. Images were sometimes distorted and flickery.

 

Nonetheless, 3D remained popular for a while because it was a novelty. But after a while, it fell into disuse.

Modern Glasses

What 3D really needed was the right technology to give it a boost. This technology has now arrived.

 

The quality of 3D on the latest TVs is remarkable. Take a look at Panasonic's Full HD 3D TVs and see for yourself.

 

But you can't get away from the simple optical fact that our eyes cannot appreciate 3D TV without glasses. The latest answer to this is liquid crystal shutter technology. When you wear a pair of liquid crystal shutter glasses, you can watch 3D films and broadcasts on a compatible TV.

 

With a Panasonic 3D TV, for example, the right and left liquid crystal lenses of the glasses close and open in turn. They do this in conjunction with alternating right and left side images on the TV screen.

 

To achieve this, the glasses link directly to the TV with an infrared transmitter. Such glasses are truly state-of-the-art. And when you try a pair and watch a sports broadcast or a film, you'll see why reviewers are saying the future of TV is 3D.

 

If you have a chance, go along to a 3D demonstration at a local TV retailer. See for yourself what the fuss around Full HD 3D TV is all about. And experience the next level of home entertainment.

 

Plasma TV has taken a leap forward. The latest plasma 3D TVs with liquid crystal shutter glasses open up a new world of entertainment.

emission standards to begin daily glass industry Formulation

In the system of "national environmental standards, examination management practices, "the relevant provisions of the State Ministry of Environmental Protection Science and Technology Department of the meeting Beijing's January 22, the National Environment Protection "emission standards for the glass industry - glass container" standard argument of the question be open.
"The emission standards for the glass industry - glass container" is the State Environmental Protection Administration issued a standard element, the Chinese Academy of Environmental Sciences, Institute of key organizations to develop standards, design Bengbu Glass and Research Institute, China Light Industry Cleaner Production Center as a standard for the basic units of organization, committed to establishing standards.
Conference on "initial report" had a serious argument. Given the difficult to fill the glass industry glass containers to date, and the proposed standard for the name was changed to "emission standards glass industry by day," taking account the industry daily production of glass, the complexity of the proposed rules for the preparation of business units daily production Glass is devoted to research, listen to the views of industry experts for the establishment of standards more in line with the reality of industry. The meeting of the perfect system of regulations and technical standards to develop emission standards for the glass industry is very necessary because they "daily emission standards glass industry. "Formulating an action plan in accordance with schedule, the standard was completed in April 2011 the draft standard for approval. About the Author
