3D Flat Screen – How It Works

by Amie Valenzuela

The latest craze in modern electronics, is beyond the shadow of a doubt 3D television. People want to watch 3D movies in their own home, now that they have seen them in cinemas. The supply of 3D technologies is growing rapidly these days. There exist several technologies to create a 3D image on televisions.

Some ways of doing it are more pricey than others. Yet other methods are more feasible than others. There are a lot of trade offs to keep in mind when thinking about how to bring 3D to the consumer’s home. There exist three main technologies for creating 3D images on televisions.

Lenticular viewing. The Philips company came up with this one over a few years ago. A special 3D set of glasses are required to watch television in three dimensions with this technology. A lot of people, however, feel the glasses are kind of cumbersome. The lens used in televisions based on the lenticular viewing concept, send a different image to each eye. The image that is sent to the left eye, is going to be only slightly different from the one for the right eye. These type of televisions will have a very small viewing angle, unfortunately. It’s impossible for multiple people to watch this in all its three dimensional glory.

Passive glass systems. Hyundai is now working on a flat screen that you can use for either 2D or 3D movies on. A 3D glasses is still required for viewing three dimensional movies on these screens. The television will display two overlapping images. Because of the polarized lenses in the 3D glasses, each eye only receives one of the images. A very impressive three dimensional effect is created this way. Today, these kinds of screens are already out on the market. A typical size for these screens is about 50 inches.

Active glass systems. This technology is much like the passive glass system, but not quite. The main difference is that the 3D effect doesn’t come from the television. Instead, the effect comes from the glasses almost completely. First, the glasses must be synchronized with the refresh rate on the television. Images for the left and right eye will then be displayed alternatingly by the television. The shutter system in these glasses will make sure that the right eye only sees the images for the right eye. It goes without saying that the same happens for the left eye. Because of how this system works, the television’s refresh rate is basically cut in two. It’s highly recommend that you get a television with at least a 120Hz refresh rate when using active shutter glasses.
