3D TV without Glasses
With all types of TVs such as the LED, HDTV and 3D TV with glasses, there is buzz building which is around 3D TVs without Glasses. Sounds pretty amazing, but is this technology innovation really coming to reality? There’s no question 3D technology is moving at a very rapid pace and it does seem that days where we can enjoy 3D television without any kind of glasses may seem realistic. With ongoing battles between active and passive 3D glasses, critics and experts agree that they are the cause of difficulty in adaptation of 3D TV technology. Many people who do wear 3D glasses often complain of eye strain and experience headaches quite often. If the new 3D technology without glasses was to work, it would be very interesting how this will all play out.
The fact of the matter is, 3D glasses free technology already exists. The problem though is the technology is still in the making and all the bugs are being worked out. It is referred by experts as the ‘auto stereoscopy’, creating a natural effect when we are able to see objects in front of us in the real world. To create the 3-Dimensional effect, there are 2 primary technologies which are used to generate the 3D effect without the requirement of asking people to wear a pair of 3D glasses. One of the technologies utilizes a lenticular lens which is shaped a little bit differently to create a different image for your eyes, therefore a stereoscopic effect (3D effect) is the result. Toshiba is going full force on this tactic with it’s latest and newest 3D TV release. The tricky part is making the technology available at a competitive price so that it can be more affordable by consumers.
Additionally, the other technology which is utilized to generate a 3D effect is known as the ‘parallax barrier’. This is accomplished through a device placed on top of a television over the screen of the LCD. The technique is actually proven and is already being used by companies as Nintendo for its 3DS gaming platform. Other type of experimentation is also being performed (Integral Imaging). Each of the independent technologies definitely has its pros and cons and new technology is continuing to be developed throughout the year as well.
3D Glasses achieve something called ‘Filtering’, which uses parallax barrier technology. A TV screen has a layer in front that contains tiny holes which act as the filter. Our eyes are able to see all of the individual and unique pixels which generate the 3D effect due to these holes. Brightness reduction however occurs, as the individual is not able to see the full screen due to only particular pixels of light that are achieved over the screen. Finally, the individual has to be positioned and sitting in a sweet spot can really only enjoy the 3D effect.
While 3D TV without Glasses technology is still new and in the making, the battle continues to heat up between the big brand electronics manufacturers. We’ve seen the latest at CES and only time will tell how this technology will evolve. For now though, 3D TVs offer a solid and fun home experience through utilization of 3D glasses. Just be sure to do your research to make sure you make the right choice if you plan on making a purchase.
