3D TV with glasses: the beginnings of a new dimension.
The recent wave of information on the introduction of 3D TV, like the launch of films like “Avatar” and “Alice in Wonderland” raises a lot of questions. But can you experience the 3D comfortably in your chair? Although 3D TV with glasses has started to take off we explain a bit more about what is behind 3D Tv with glasses.
What is 3D TV?
The big difference with the normal TV (2D) and 3D TV is that with 3D, our eyes should see two different images which largely overlap. The principle is similar to our everyday vision: our eyes see two images continuously with a different angle that corresponds to the distance between our eyes.
3D TV is trying to imitate this principle so that each frame generates two images from a different angle. These two images are then displayed simultaneously, or quickly one after another. One is only for the right eye and the other only in the left eye. This allows our brain to imagine the depth of objects and give us a sense of 3D as in reality.
What hardware is needed for 3D TV?
You will need of course a 3D TV that is built to broadcast 3D images. In fact, not surprisingly, the TVs of the previous generations will not pass for 3D TVs. You need a TV designed for this new technology, which therefore has new technical features like a 1.4 version HDMI connection and the ability to support a video signal of 120 Hz. The first models that were launched in stores were designed to be used with active 3D glasses. These 3D TV glasses are synchronized with the TV via an infrared transmitter. The right and left obscure glass and then show the image so that each eye does not see the image intended for it, creating the 3D effect. The system already exists but the system without glasses is not yet commercially available and is therefore expensive
