Whats the Difference Between Active and Passive 3D TV Glasses?

One of the first questions viewers ask when thinking about 3D TV is "What is the difference between active 3D glasses and passive 3D glasses?" After all, it is the glasses that make it possible for the viewer to actually see the 3D image produced by the high-end home theater system. They can also be a major factor in the cost, as every viewer needs a pair of 3D glasses, which can add up, particularly for those with large households. The basic answer is that the active glasses do more to produce the 3D effect for the viewer while passive glasses simply work because of what they are rather than what they do. The most important thing to remember is that the two kinds of glasses work with radically different 3D implementations, and it is very important to make sure the glasses match the technology of the television.

Where to Buy 3D Glasses

With the increased popularity of 3D television, particularly when combined with the desire to show 3D movies in a home theater environment, the necessary glasses have become widely available. Interested consumers can find them in many local brick-and-mortar stores, particularly dedicated electronics stores but also in major retail chains. Prospective 3D viewers can also find them online, both at Internet retailers and auction sites like www.facebook.com/jaffnaElectronics

The biggest difference between active and passive 3D glasses is that active glasses use power and passive ones do not. Each technology has its advantages and disadvantages, and neither is a perfect solution for all users. Passive 3D glasses are lighter weight and more suitable for extended viewing; they are also easier to use: simply put them on and start watching. Active 3D glasses provide a higher quality image without the jagged lines associated with passive 3D glasses. They also require synchronization with the TV and sufficient power for the entire viewing session. Passive 3D glasses require that the TV have a special coating on the screen that is only available on LCD and LED LCD TVs, while active 3D glasses can work with both projection and plasma TVs as well as the LCD variants. Consumers wishing the absolute highest quality 3D image and those who wish to use a TV other than an LCD-based 3D TV should choose a solution using active 3D glasses. Those looking for a solution that is less expensive and easier to implement may be better off with passive 3D glasses.
