3D TV: What Makes 3D TV So Special?

By Nick Mcdonalds


3D TV technology started in 1833 when Sir Charles Wheatstone created the idea of reflecting mirror stereoscope. This device works as and reflector creating different images. The concept of 3D is that two images are being combined by the brain creating the so called 3D effect. Making two sets of shutter for each eye to close and open simultaneously creating the 3D effects. The very Television you have is actually capable of creating 3D images and there are a lot of ways to project 3D effects only that the finest technology will determine the amusement of the results.


A vintage television is equipped with the 'anaglyph' technology. It is one of the very first edition of the type of 3D during the early days. It materializes images by the use of colored cardboard glasses (a low tech. version of 3D) that doesn't seem to be working effectively.

Theaters of today use a special type of glass to project 3D images on screen. This glass is called polarized glasses. It is designed to make a special type of screen used for projecting special images making angles with various polarizations. Although it is not yet perfected, many latest upgrades are being made by most popular brands of HDTV's and still on the stage of progress. But by far 3D technology's simultaneous alternation concept brings out the best and the easiest way to do projections rather than the Plasma TV's and LCD TV.

During the 21st century, rapid evolution of 3D technology has introduced different types of high tech television today. The LCD TV and Plasma TV offer as much high quality images that can arguably compete with 3D effects. But if there is one aspect that would give an edge to 3D, is the shutter technology that is developed for a true to life watching of motion pictures and images.

This shutter technology works by blocking on eye while enabling the other to process the image in such a fast phase, it also uses an LCD electronic glasses that is built inside. The television portrays one image at a time while the glasses covers one eye for viewing, this happens at the rate of 60 fps that only a single flick is noticeable or if not negligible by the naked eye. This is way better compared to the other HDTV's available in the market as they have certain issues like double imaging or ghosting and cross hair which is annoying and eye straining as well. Ghosting happens due to the distorting of images and color, the image seen in the other eye was supposed to be for the other eye creating pale outline on the area of the screen.

On the other hand, expect that 3D TV is evolving every now and then. More new features and enhanced graphics will be introduced in the days to come.
