3D TV without glasses?


We would have probably bought into 3D TV earlier, if we didn’t have to worry about the 3D glasses. For those looking for a 3D experience without the glasses, there is some hope. At Consumer Electronics Shows, several companies have proposed solutions for 3D TV without glasses.

3D TV glasses are sometimes associated with discomfort, headache or nausea. Also, how many do we need 3D glasses in a home of maybe 4, 5 or 6 people? And what if there are more viewers? Can we achieve the perfect 3D TV experience without needing 3D glasses?

To do this, there is a process well known: the lenticular process. This method involves coupling a screen with a lenticular film. This film has a smooth side (glued to the screen) and a side made up of striated lenses. These lenses are designed to direct the light images into your eyes. The screen diffuses 2 images, which are each directed to one of your eyes. It then remains your brain for long enough for it to to interpret these 2 images into a 3D representation.

Of course this technology uses a 3D content format particular when interlacing 2 sets of pictures between them. If you look at these images on a screen that does not have a lenticular film, you would see a blurred image (like that).

Another problem with this technology is that it is very dependent on your position in front of the screen. If you move a little to the right or left, the picture may not be in 3D, but instead it will become blurred. The work of the viewer is to find a position where he will see the film in 3D. One can imagine a new generation of television that will include cameras to monitor viewers, to adapt the images broadcast to their position.. But until that can happen, we are going to need our 3D TV glasses to enhance our viewing experience
