3D TV TECHNOLOGY, 3D TV SPECS, 3D TV FEATURES.

For the past 15 years, Philips has been at the forefront of 3D display technology. In that time, we have developed the expertise necessary to provide 3D quality both for specialized and mass-market applications. In this backgrounder, we will show you how 3D technology works and explain why the approaches of Philips 3D Solutions are particularly effective.
                                  
The next massive breakthrough in TV technology 3D has been demonstrated by Philips. The technology which will change the way TV is viewed will deliver a massive breakthrough for advertisers and movie makers.
3D is cool!
Having a night in with your friends? There is no better way of watching the latest movies, the coolest shows, and the most important sporting events, than in an exciting 3D mode!!

3D is going to be big!
There are great opportunities for consumers, as well as business and the professional market. Just imagine what 3D can do for the visualization of your product.

3D is the next big thing!
Hollywood is already shooting some big productions in 3D. They also know that soon, everybody will want to see their favorite movie in 3D!

Grab viewers attention and bring your content alive with WoWvx technology!
Imagine what Star Wars would like on a 3D screen! It’s like being there, in a Galaxy far far away yourself! And try to resist that freshly squeezed glass of orange juice springing out of the screen!

3D is based on the way the human brain and eyes work. Because the pupils of a person’s eye are about 6.5 cm apart, each eye views a scene from a different angle and generates a unique image. The brain merges the images to create a single picture. The slight difference between the image from the right eye and the image from the left eye allows the brain to judge the depth. Stereoscopic vision is attained.

Our ability to see in 3D is about perceiving depth. How far away things are from us. A combination of several components allow our brains to perceive our 3D world around us. Perspective is one, where things further away appear smaller. But that can sometimes trick us. Close one eye and look around you. You will immediately notice that the distance of the things around you is not so obvious. If you hold up two things in front of you and move one closer and further away, you will only be able to judge which is closer by their relative sizes. Some optical illusions rely on this by having smaller than usual objects closer to you, so creating the illusion of them being further away.

Another aspect of depth perception is focus. Look at your hand outstretched with a distant background. You will see your hand in focus but the background out of focus.
                
The final component of depth perception is only available to us because we have two eyes. Because our eyes are spaced apart, each eye sees a slightly different view. Our brain combines these two slightly different scenes and gives us a sense of how far away things are. A simple way to demonstrate that to yourself is to hold one finger up at arms length. Then close each eye in turn, and notice the position of your finger compared to the distant background. With your right eye open, your finger will appear to have moved to the left relative to the background.

3D TV TYPES, 3D TV SPEC, 3D TV APPS, 3D TV REVIEWS.

                             

There are two main types of 3D technology that are ready for you to use now. Commonly known as 'active' and 'passive', the two types deliver a similar effect, but have massive differences in the production cost, and how it is passed on to you, the consumer.

Active-shutter 3D is going to be the way most people end up seeing 3D in their homes. With this technology, the TV is basically the same as your current one, but with some increased performance to make the 3D look as good as possible. To see 3D, you'll need a special pair of glasses that contain a system that shuts off the light to first one eye, then the other.

While the glasses are blocking light to one eye, the TV is showing an image to the other eye, then the process switches, and the TV shows a separate image, shot at a slightly different angle, to your other eye. This synchronized shuttering basically provides a Full HD video stream for each eye, each very slightly different. Because your brain is translating two separate signals from your eyes all the time, it's fooled into seeing 3D.

The passive system, by contrast, uses a very simple set of glasses. These use circular polarization to provide each of your eyes a different image from the same source. In cinemas, this works because two images are projected on to the screen in quick succession. They appear at a rate of 144Hz through a special filter that adds polarisation, alternating between the left and right eyes, 72Hz for each.

Translating the passive system for home use would produce much more expensive televisions. These would need to have a panel fitted in front of the LCD or plasma panel that alternated in time with the left and right images. LG is using this system in its 3D TV for pubs.
                             
There are several different methods to create the 3D effect, including anaglyphic, polarization, alternative-frame sequencing, and auto-stereoscopic displays. All but auto-stereoscopic require some type of glasses, whether it is red-cyan, polarized, or active-shutter. Both Panasonic and Sony have developed alternate-frame sequencing 3D TVs, while LG and Philips are working on auto-stereoscopic displays.

Yes, you must wear 3D active shutter glasses in order to view 3D TV. Philips and LG are developing a 3D TV that doesn’t require glasses to come out in 2011. TCL also just unveiled a 3D TV that has a rippled screen instead of requiring glasses at the CES that will be available in 2011.

Discovery, IMAX and Sony are working together to develop a 24-hour 3D network to come out in 2011 with entertainment, sports, and natural history tv shows. ESPN will have an all-3D channel premiering on June 11, 2010 for the World Cup that will air at least 85 events (including the Summer X Games, college basketball, and college football) for one year. When events are not playing on ESPN’s channel, the screen will be blank. DirecTV and Panasonic have announced that they will work together to start 3 HD 3D channel by June 2010. They plan on broadcasting MLB All-Star games, MTV, CBS, and NBC.
