3D TV: Things You Need to Know

9 July 2013 No Comment

3D TV is a deviation from reality. It creates optical illusions so as to make something look as it is, when it’s not. In fact, it is something akin to just fooling the brain. 3D TVs are entirely different from HD TV. With 3D glasses on, each eye sees a slightly different image, and these TVs are designed to give idea of watching 3D content on your own TVs at home. These TVs are flooding the market and it would be good to know a few facts  before you decide on owning one.

Which Model to Buy

Decide why you want a 3D TV first. Then find out which one you would be able to afford. If you are keen on watching 3D Blu-ray movies, you will find an Active Shutter 3DTV that pin points every pixel of a 3D Full HD formatted film. Panasonic and Samsung provide you with such models. All Active Shutter 3D TVs use bulky 3D glasses that are expensive. They offer only one or two pairs of 3D specs. And, if you are keen on watching Sky’s 3D channel, it is best you look for LG’s Cinema 3D line-up that use passive 3D tech. Further, 3D gaming works excellent on both Active Shutter and Passive 3D TVs.

How to Choose the Best?

The answer is simple. The one you should look for is the biggest model. However, it needs to be noted that the best TV does not depend on size. Panasonic’s VT30 series with plasma panels are the best 3D TVs around, though cost friendlier ones are the GT30 and ST30 series. Samsung’s 3D plasmas are also a real competitor. Samsung, Sharp, Sony, Panasonic and LG all make good 3D LED TVs using Active Shutter technology. It might be noted that a 32-inch 3D is designed for convenience and not for effectiveness.

Glasses Tagged Along

Active Shutter 3D TVs use battery-powered glasses that sync with the TV for displaying the correct image. It is done by polarizing the image into two. Each eye gets a slightly different feed, while the illusion of depth in a flat image follows.

3D TV Sans Glasses

An auto-steroscopic TV has a lenticular lens embedded in its glass panel which helps in 3D viewing. There are two issues regarding this 3D without glasses. First, is that the lens cuts down on resolution highly which implies that actual 3D panel needs to have a ‘4k2k’ resolution. A big issue could be the number of ‘views’. There are so many ‘corridors’ or 3D ‘sweet spots’ on screens. This makes your head move from side-to-side resulting in headache. 3D viewing is deprived outside 40-degree area in front of the screen. Toshiba plans to bring 12-inch and 20-inch auto-stereoscopic 3D TVs to market next year as well as a glasses-free 3D laptop.
