What is 3D TV?

3D TV is a type of TV that is capable of viewing 3D content. The principle of operation of 3D TV is that the TV screen will display 2 frames at the same time, one for the left eye and one for the right eye. When watching 3D TV, users often have to use 3D glasses (some new technologies can produce 3D TVs without glasses, but at the moment it is not popular) whereby 3D technology is divided into 2 types: 3D active and passive 3D.

What are active 3D glasses?

Active 3D glasses are glasses with a liquid-crystal shutter and are battery-powered (that is, when you want to use them, you need a battery). The working principle of active 3D glasses is to continuously open and close the two sides of the glasses so that at a time only one eye can see the image on the screen and create a 3D effect. For this type of glasses, the image will be displayed at least 60 frames per second.

Image quality

The advantage of active 3D technology is that viewers can enjoy detailed 3D images in both eyes with high quality and fidelity. Images are displayed with beautiful Full HD definition.

However, the limitation is that users need to be equipped with active 3D glasses (the cost of active 3D glasses is quite high, ranging from 200 to more than 1 million VND/glass). In addition, 3D glasses use batteries, it is quite heavy and requires the viewer to keep the correct head position or else the image will not be displayed clearly.
