3D TV Without Glasses is Now a Reality
So, when are we going to see 3D TV without glasses? The 3D craze is, it seems, here to stay, but one thing everyone agrees on, is that it would be better to view glasses free 3D TV.
Why Do We Need 3D Glasses?
In order to see things in 3D it is necessary that each eye sees a slightly different picture than the other. In real life this is done naturally, with the eyes being placed apart from each other giving each eye a different perspective. The two pictures as produced by the eye are then sent to the brain where the pictures are pieced together to create a three dimensional image that had depth and texture.
When viewing a 3D motion picture, this effect is achieved by the use of 3D glasses which interpret the specially crafted images as three dimensional images. The only problem is, 3D glasses are a bit of an annoyance, and many people are waiting for glasses-free 3D TV before investing in 3D technology.
When Will We See Glasses-Free 3D?
While glasses-free 3D TV is not yet available to the general public, a few of the major TV manufacturers (LG, Sony and Toshiba) have had prototype models of glasses-free 3D TV’s on display for a while now. But there is still no set date as to when these models will be available for general purchase, and that is probably because these prototype models are still plagued by a host of problems.
First off is the limited viewing range. You have to sit fairly close to a glasses-free 3D TV in order to get the 3D effect, and angled viewing gets distorted. Then of course there is the problem of overall effectiveness. The prototypes just don’t have the 3D depth that we have come to expect from viewing 3D movies in the theaters. The effect of the glasses-free 3D TV sets is quite subtle as to be almost imperceptible and definitely not worth the money that they will initially cost without some major improvements to their design and features.
Interestingly enough, the one actually good 3D TV prototype was not made by one of the large companies, but by a relatively small company called “iPONT”. iPONT uses an auto stereoscopic 3D display which they hook up to a box that they call a “3D TV Box” While the distance and angle problems were still there, the 3D images are actually quite as good as the 3D televisions currently on the market. This, of course, is a bit of a thorn in the side of the big 3D companies, but it just goes to show that while changes are coming, they are coming slowly, and the chances are that we will not see a marketable glasses free 3D TV for at least five to ten years.
