It has only been in the last twenty years or so that 3D TV has ceased to be the stuff of science fiction writers and joined the realm of potentially viable technology. In recent months a number of 3D television manufacturers have been promising that the latest flat screen high definition sets, which are projected to be on the market in the near future, will have a 3D function. While this is a new thing in the realm of television, most manufacturers are simply adapting nineteen sixties cinema technology, by the use of special glasses that work with high definition blue ray machines.
3D glasses work in much the same way as the human eye, so you actually get two different images through the glasses. In order to grasp the depth of an image our eyes need to see things from two perspectives. 3D glasses work in a way that is compatible with our eyes and basically turns a flat image into one that has depth. Many films have been made with 3D in mind such as Avatar and the new Harry Potter film.
While most manufacturers will be working with the use of special glasses, Panasonic, Toshiba and Sony say that people viewing on their sets will be able to do so without the glasses. These companies have made some heavy investment in television that has a 3D functionality. A favourite means of introducing this functionality is the adaptation of existing LCD sets to deal with a three dimensional function. Panasonic are launching their latest VT25 screens, as they alone are saying that the best television sets for 3D enabling, are the plasma sets.
