Ever heard about 3D TVs? Well, having a three-dimensional TV is not impossible. After all 3D images have already been developed in the world of photography and film.
You may not know it but 3D images in films were once very popular even before World War II. But when the war ended, this type of 3D technology was no longer seen. It is only now that some companies have striven hard to produce their respective 3D TVs to be able to compete in a futuristic market.
3D TV development timelines
The use of 3D images is always influential in the 3D TV development in this age. These images were discovered in 300 BC by Euclides. It was only Leonardo da Vinci who started some processes to convert images into three dimensions. In 1844, David Brewster launched the equipment known as Stereoscope. This device can be used in raking photographic pictures in their 3D formats. This was then enhanced by Louis Jules Dubosq. Since then, the stereoscopic camera became popular to every home. But when the World War broke, pictures where then turned back into black and white as inspired by the war journal.
In line with the launch of the stereoscopic camera, 3D development in movies transpired as well. In 1855, a stereo animation camera known as Kinematoscope was invented. It was in 1922 when the first 3D movie entitled Power of Love was shown publicly.
When the television was launched during the 50's, 3D Movies became even more popular - from Robinson Crusoe in 1947 to Bwana Devil in 1952 to the House of Wax in 1953. But it is sad to note that the expansion of 3D movies was put to a stop in the 70's.
In the 1990s however, 3D episodes were launched on TV. This was used by most television producers to attract audiences and increase their ratings. Since then, many broadcasting networks from all over the globe started efforts to produce more 3D episodes. Early this year, South Korea's Korea Digital Satellite Broadcasting launched its 3D Channel. UK will follow suit with British Sky Broadcasting Company's launch of the Sky 3D Channel by April of this year.
Companies developing 3D TVs
As of the present, there are 3D-compatible TV sets that are out in the market. Those with LCD shutter glasses that operate in 2D mode also have 3D TV capabilities. These ones are creating stereoscopic images typical to what stereoscopes in the older times were able to produce. Television sets that support a refresh rate of at least 120Hz and have an HDMI 1.4 configuration are all 3D-compatible TV sets.
To improve all these things however and to introduce consumers with the "real 3D TV", various electronic companies have worked on their respective technologies. For instance, Samsung and Mitsubishi use Texas Instruments' DLP technology to produce 3D TV models. Toshiba, Sony, LG and Panasonic will launch more 3D TVs by this year. Phillips, will have to wait for its turn until 2011 as it is still developing 3D television sets that will no longer need special glasses.
