3D televisions make this news lately when some were announced in the 2010 CES. Also known as 3D ready televisions, these TVs possess the capacity to project video at stereoscopic 3D. John Logie Baird first pioneered the televisions in 1928 plus they later evolved to incorporate cathode-ray tubes to ensure they are are more effective and appear more real. Then, within the mid 1930’s, still cameras while using 3D technology grew to become commonplace products.
Presently, the primary technologies that brought towards the producing of 3D video and pictures on televisions include:
– Polarization 3D, which using lenses which are polarized passively
– Shutter lenses, that are active with alternate frame sequence patterns
– Autostereoscopic lensless displays, or Auto 3D, as it is termed to commercial dealers
– Anaglyphic 3D, the more prevalent from the technologies and uses the glasses to process
Probably the most utilized from the technologies may be the Stereoscopy method, which utilizes a “two-view” setup. This setup uses cameras which are positioned alongside one another to simulate the space from a person’s eyes then projects two different two different views one for every eye thus allowing the 3D effect.
The current tv sets that utilize the 3D technology still needs using special glasses to help make the 3D images appear, however, these televisions don’t constantly transmit the pictures in 3D they are able to switch backwards and forwards between 2D and 3D when needed. Some popular modern 3D televisions include Panasonic, Texas Instruments, The new sony and LG, amongst others. Actually, the LG 3D television only agreed to be announced on June 21 2010 because the first full Brought High definition tv that’s 3D ready.
The refresh rate from the televisions is usually greater than regular televisions and needs no less than 120Hz, nevertheless the greater the refresh rates are on the 3D television, the greater the 3D effect can look. It is because the refresh rates are divided between both eyes. For instance, the 120Hz refresh rate will project at 60Hz for every eye with the glasses. Even in the cheapest refresh rate of 120Hz, these kind of televisions have a refresh rate two times up to the older or “outdated” technologies utilized in others than 2D televisions do. These televisions offer the greatest resolutions offered at either 720p or 1080p.
Furthermore, to achieve the entire HD 2D experience, the consumer 3D television watcher should use a full HD 3D Blu-ray player with the television. This can offer not just the very best in technology, but the greatest 3D capable viewing experience possible in modern occasions, along with a disk made specifically for 3D viewing and compatible glasses.
