The thirteenth sign of the zodiac, Ophiuchus. Types of 3D glasses

There are several types of 3D glasses on the market. On the one hand the typical two-color glasses, known as anaglyph glasses and other passive and active. 3D movies like Avatar, which viewers have enjoyed in the rooms are usually displayed with passive glasses, while the new 3D TV requires active glasses. What are the differences between each other?

The first glasses to view 3D anaglyph glasses were the typical glasses with lenses of two different colors. This difference in coloration of the glasses used to filter the colors differently receiving eye. As Sony explains technician during the presentation of 3D TV, "because it would not really be always red and green, because what really matters is that the colors are completely opposite in the color wheel." Thus, it could be that a lens color was yellow and one purple and one blue and one orange.

With the evolution of technology and improving the quality of three-dimensional imaging has also led to the development of new display systems. This is the case for glasses polarized. In the film two projectors polarize light from a different angle for each eye, so glasses to decode these images provide more quality.

The problem is that this system can not be applied to televisions, as the filter built into the front of the screen only allows the reproduction of half the content and brightness. In addition, as noted from Panasonic, "another of the disadvantages of this format is the limited viewing angle, and that users should keep your head up to avoid causing eyestrain double wrap."

active 3D glasses

is for them that experts and researchers have had to use other techniques to make 3D comes to conventional televisions. Active glasses are the solution. This type of eyewear includes an infrared sensor that synchronizes the images alternate on the screen so that the left eye sees only the left and the right perspective right. In fact the infrared sensor simply synchronizes the image to be displayed for each eye, the true cause of the display or not the image are the LCD crystals containing the active shutter glasses and rapidly alternating images on the screen. The flickering and image change from one to another eye occurs so fast that the brain does not get notice the change and interprets it as a single three-dimensional image.
The price of this technology is still very active glasses high. Each unit, according to Sony, one of the brands most are betting on this technology, will cost around 100 euros. Still, the brand also reported that the launch two glasses and a transmitter cost about 200 euros.
