The History of 3-D Television
With many of the best OLED TV reviews citing the 3D feature, people certainly find this technology desirable. A 3D television projects a program in a realistic three-dimensional way. It uses a variety of techniques to create this experience.
In the past, 3D television was delivered through a multi-view display, 2D-plus-depth, a stereoscopic display and a modern 3D display. The concept of a 3-D movie process was patented in the late 1890s by William Friese-Greene. It showed two images view stereoscopically produced a 3D perception the the brain.
By 1915, 3-D technology was tested on audiences in New york City by William E. Waddell and Edwin S. Porter. The stereoscope itself was improved in the 1850s. In 1915, anaglyph was invented by L.D. DuHauron and the use of red and blue glasses to watch 3D was introduced. The idea caught on quickly and by 1922, the first public 3D movie was shown.
Stereoscopic 3D television was aired as early as 1928 by John Logie Baird, a television innovator. The 3D television system used cathode-ray tube and electro-mechanical techniques. The first color 3D movie was produced in 1935.
With the increasing popularity of TV in the United States in the 1950s, more 3D movies were made. In 1952, United Artists’ Bwana Devil was seen across the country.
Various techniques are used to display 3D programming. Lenses are used and sometimes lenses are not used to view 3D movies and television. Lenses including passive red-cyan called anaglyphic, heat-mounted displays, alternative frame sequencing using active shutter lenses and polarization with passive polarize lens glasses. Autostereoscopic displays, or auto 3D, do not require lenses.
Hitachi and Sony are working on updated technologies to deliver 3D projection without glasses. Other technologies used to deliver 3D displays include the Pulfrich effect, holography and volumetric display. High end television sets currently offering this technology include Bluetooth, Ethernet, USB Wi-Fi and USB player and recorder.
TV sets typically supporting HDMI and are 3D ready operate in a 3D mode. Glasses may be sold separately. Panasonic and Toshiba also working on using autosteroscopic technology to deliver a glasses-free 3D television experience. TCL Corporation already sells a 42-inch LCD 3D TV, TD-42F, in China that does not use special glasses.
Samsung already offers the LCD 750, PDP 7000, LED 7000 and Blu-Ray 6900 as they continue their development of the best OLED TV. Other companies working on the 3D television series include Philips, Sony, LG and Onida. Toshiba showed 20-inch and 12-inch LCD 3D TV sets for possible commercial launch. There is also the LG Full HD 3D and the Panasonic Full HD 3D hitting the market.
Television companies and content providers are working to standardize 3D for use in home electronics. Over the past two decades, many television shows were aired in 3D and the response was excellent. More 3D projects are being developed as this technology becomes desirable for people who want the
best OLED TV with 3D viewing.
