3D glasses Sony TDG-BT500A: description, characteristics, advantages

For some half a century, the TV has undergone an amazing evolutionary path: from huge lamp boxes with a small black and white screen and a vague image to delicate thin panels of impressive size that can transmit not only the colors of the surrounding world, but its volume.

Television technology is constantly being improved. More recently, a real breakthrough was the appearance in theaters of 3D movies. They amazed spectators with grandiosity and realism. The film industry received huge profits, stamping all the new paintings that gathered full halls. And today, 3D content can be watched without leaving home, on modern TVs with the help of special glasses.

3D glasses Sony TDG-BT500A

Sony is famous for its ability to quickly master advanced technologies, to create on their basis sound and reliable products with guaranteed quality. Did not become an exception and 3D-sphere. 3D glasses Sony TDG-BT500A are designed for branded LCD-TVs with support for active 3D technology.

At the moment, the two most popular ways to transfer a three-dimensional image using a TV are: active and passive. Sony chose the first option for its devices. To understand the merits and demerits that have active Sony 3D glasses, you need to understand their principle of action.

An active 3D TV alternately and very quickly transmits to each eye individual frames that are slightly biased relative to each other. Thanks to this effect, the brain perceives the image as three-dimensional. 3D glasses Sony made with the use of liquid crystals, which act as a shutter, veils for the eyes. They are synchronized with the TV and at the right moment they darken the left or right lens alternately. That is, the human eye sees strictly defined frames that combine into a realistic, deep picture.

In passive 3D technology, the volume is also transmitted by two biased frames, each designed for different eyes. But both frames have different polarization and are enclosed in one screen using horizontal alternating lines. Polarizing glasses allow the eyes to see only certain lines that gather in the desired frame and create a 3D effect.

The main drawback of passive technology is the loss of image quality in half, since the eyes see only half of the vertical lines. Therefore, people who want to get the most close to reality images, no doubt choose a technique with active 3D. Costs more than pay off the pleasure of watching movies, sports matches, music videos in the highest quality.

disadvantages

The main disadvantage of Sony's 3D glasses is their high cost, but it's fair to say that a really high-quality thing is worth its money. Buying branded, time-tested and thousands of consumers' glasses, the consumer gets guaranteed reliability, durability and access to the magical world of 3D content with the maximum resolution.

Another minus of glasses is called too large lateral gaps, through which the eye drops a lot of light, interfering with watching TV in the afternoon. But, as a rule, the eyes quickly adapt to this inconvenience and cease to notice it, especially when watching a fascinating film that is difficult to distinguish from reality.
