3D Television Review

People who are movie fans probably remembered the old blue and red goggles which were used for the first generation of 3D movies. While interesting new technology has progressed, 3D television technology is now starting to advance and turn our living room experience into a new virtual world. In the near future your next TV may be a 3D television.

The basics of 3D are simple, in that instead of having a flat image the digital television sends two slightly different versions of the same image to the left and right eyes. This process naturally creates the perception of depth when we look at the world. And when done through electronic methods it creates the same effect.

To create this effect, currently individuals need special lenses to make it possible. At a movie theater two different images are projected on the screen during a 3D movie. Each lens is designed to show part of the image to each eye. And when combined create the total stereo image. This is known as passive or polarizing lens technology.

Modern 3D televisions use a different variety of 3D glasses that use something known as active shutter technology. A pair of glasses are typically designed for a particular unit, such as a Samsung 3D television. These units sync with the television through radio, blue tooth or infrared technologies. The TV sends separate signals that are coordinated with the liquid crystal elements in the goggles to produce the stereo image.

If you are looking to buy a 3D television there are some important things to look for. First you need to find a high quality unit like a Panasonic 3D television. You have to get a unit that can handle the resolution requirements for creating 3D images. Since the TV has to project two separate images to create the effect the refresh rate needs to be at least double that of normal TVs which is 60hz, so this would mean 120hz or more.

Second glasses for the 3D TV have to match the television you’re using them with. For the 3D effect there is no such thing as a “generic 3D goggle set”. Each set of 3D glasses will work for a specific brand, and there are differences in batteries, weight and whether the 3D glasses can be used over prescription eye wear. So try out the glasses to see if they are a good match for you.

Third for viewing 3D movies you will need a blue ray player capable of decoding 3D disks. Many newer players have this capability built-in, but you should check your current unit or plan to upgrade before you get a new 3D television. As an alternative, in the future DirectTV, cable and other services will be providing more 3D channels and content.

The last detail is you will need to upgrade your cabling. To handle the extra data requirements of 3D signals you will need HDMI version 1.4 cabling for your 3D capable devices. You will not be able to use lesser cabling for your 3D television sets.

Active 3D technologies are relatively new they are quickly growing in popularity. More media outlets are providing movies and programs in 3D. The cost difference between 2D and 3D units is shrinking. And newer technology such as 3D displays that don’t require 3D specs is being rapidly developed. There is no avoiding it, but it looks like 3D technology is here to stay.
