HOW TO WORK 3DTV TECHNOLOGY

The DTI (Dimension Technologies Inc.) team is getting ready to demonstrate the first step toward the world’s first dynamically switchable High Definition 2D / High Definition Autostereoscopic (no glasses) 3D Television.Our unique approach to autostereoscopic 3D uses backlighting behind an LCD to create 3D, which unlike previous approaches:a. Displays full resolution in 3D;b. Eliminates color fringing;c. Does not block light;d. Eliminates Moirés;e. Eliminates “sweet spots”;f.  Maintains perfect 2D;g. Eliminates sources of tension & headache;h. Allows picture in picture 3D window.3DTV is here but 3D Computers (systems, screens, graphics cards) will be available in retailers early next year. Some computer makers are already in production of 3D models.And of course there is the availability of Internet TV streaming directly into your 3DTV. So the "3D Viewing Family" is expanding and it will not be long before it is mobile with 3D screens in mobile phones and in 3D Laptops. 3D Computers we believe are set to make the biggest impact, mainly due to 3D Games which will proliferate and that some computer owners will only have to upgrade their monitor and graphics card initially.
 
 So it will be interesting to see ho.There are a number of 3D Tv vendors in the market but which one is the one for you. Learn more about 3D and all Kinds of digital Tvs.LG has announced two TVs that it will show off at the 2011 Consumer Electronic Show (CES): the passive 3D LW6500 and the 'world's largest' backlit-LED TV, the LG LZ9700.LG LW6500 passive 3DTV The LW6500 will require the lighter, and more comfortable, passive 3D glasses rather than the bulkier and more expensive active shutter glasses.LG claims that the 3D glasses supplied with the LG LW6500 will weigh 16g. The downside of passive 3D technology is that images aren't seen in full HD resolution.While some viewers in an ESPN lab study experienced eye strain and headaches while watching the soccer World Cup in 3D, the adverse effects were reduced after viewers took breaks, the network said Thursday."We think that breaks are a good thing for 3D viewing," Duane Varan, executive director of the Disney Media and Advertising Lab, said Thursday at an event covering the results of the study. Most adverse effects are reported on the first day that a viewer watches 3D programming, and are reduced in subsequent days as viewers get more accustomed to it, he added.While some viewers in an ESPN lab study experienced eye strain and headaches while watching the soccer World Cup in 3D, the adverse effects were reduced after viewers took breaks, the network said Thursday."We think that breaks are a good thing for 3D viewing," Duane Varan, executive director of the Disney Media and Advertising Lab, said Thursday at an event covering the results of the study. Most adverse effects are reported on the first day that a viewer watches 3D programming, and are reduced in subsequent days as viewers get more accustomed to it, he added.ESPN based the study on 2,700 hours of tests it conducted at a lab in Austin, Texas, in which participants were wired to electrodes that measured everything from heart rate to arousal levels. It also used cameras and infrared technology to track how their eyes watched World Cup action and advertising in 3D compared to 2D.

 The network said it used a wide range of 3D television sets in the study, including those that used passive and active shutter lenses that are heavier, battery-operated and more expensive than their passive counterparts. Varan said the study found no difference in enjoyment levels from viewers watching the World Cup on passive versus active 3DTVs. However, users rated passive glasses as more comfortable and less distracting than active lenses.And while ESPN found few instances of headaches from viewers watching active 3DTVs, headaches were "almost not present" in sessions with viewers watching passive 3DTVs.

ESPN will produce its 38th 3D telecast on Saturday, when it shoots the Boise State-Hawaii college football game.While VP of business and strategic development Bryan Burns said ESPN will also produce 16 NCAA basketball games this season in 3D, he said the network doesn't yet plan to produce any of its "Monday Night Football" games in 3D. Burns hinted that ESPN doesn't yet have the rights to produce NFL games in 3D, noting that its deals with rights holders "are complex."Also worth noting from ESPN’s 3D study: Viewers with strong vision may not notice as much of a difference in 3D programming compared to 2D. "The worse your real-world depth perception, the better your 3D experience," Varan said.
3D advertising is more effective, with "purchase intent" from viewers watching an ad in 2D jumping from 49 percent to 83 percent while watching an ad in 3D. Viewers were also better able to recall ads in 3D.
