How Do 3D TVs Work

To understand how 3D and 3D TVs works we need to first review how humans perceive the world in 3 dimensions. We have 2 eyes a left and a right eye. If you were to take a finger and put it near to your nose and you look through your left eye and through your right eye. You can see a vastly different object. If you move the object further away and repeat the exercise. You can still see the difference between the two, but not as much as it was. So what this means is you perceive 3 dimensions when you see objects that are near to us and the 3D effect drops off as objects are further away.

When it comes the the movie-theater you have 2 different light sources, 2 different projectors that put a polarizer on the front of each projector. 1 will be polarize for the left eye and one will be polarized for the right eye. So as long as you have a pair of eye-wear which have the same polarity as the left and the right, then were ensured that the left image goes to the left eye and the right image goes to the right eye.

So when it comes to television you only have a single light source. So we have to produce a left image and a right image in a different way. We do this in a frame sequence matter. The TV produces a left image and a right image really fast. What we have to do though for it to synchronize with our eyes is we have to wear a pair of glasses that is synchronize to the television. So the television will tell the eye-wear... I am now showing the left image. So therefore the lens of the left side of the eye-wear will become transparent, the right lens will be going black. So therefore the left image is being seen by the left eye. This is all done really fast and is all blended together which is why you don't notice any quick flashing.

There is nothing wrong with plasma television or LCD HDTV in respects to 3D TVS. When it comes to 3D TVs there is a difference between plasma and LCD and that difference is fundamentally how they produce light.

LCD HDTV has to update its image very quickly. The problem with a LCD is because LCD HDTV uses technology that works as little gates that open and close to allow the back-light through. It takes sometime for those tiny LCD molecules to change their state, now this can cause a problem where the left eye sees part of the right image and the right eye sees part of the left image.

When it comes to plasma television. Your producing frame sequential images. A left then a right. A plasma television starts with a black produces its image, then erases it and then produces the next one. So when your produce a left, right, left, right, There’s little chance of getting distortion between the left and right image.

LCD HDTV vs Plasma Television vs LED TVs: which one is better?

So which one has the better picture quality, price and what room fits which TV?

Plasma television is a gas so its going start at 42 inches and go further up, The better picture quality with plasma televisions is because the gases like to be further apart from each other. That's the simple description. This also helps with making the colors look more natural. So it may be a bit more darker. Because of the gases and its quick reactions. This means the picture has better motions.

With LCD HDTV which stands for Liquid Crystal Display. Its going to be a little bit more vibrant and is a little better in glare reduction.

Light-emitting diode also known as LED TVs is more like LCD on steroids. What a lot of folks don't know is all LED TVs are LCD. The only thing LED about it is the back-lighting. The LED back-lighting will make it more energy efficient and will make your whites brighter and your dark's blacker due to the contrast ratio. Compared to LCD TVs, LED TVs are more bright and more vibrant and reduces glare, so the room your in does matter.

So which ones are better and which ones are more expensive? third place would be the plasma TV. The good side is its the cheapest of the 3 technologies but unfortunately the worse picture of the three, but that doesn't mean its a bad technology. Some customers actual like plasma more so then LED TVs and LCD TVs. A cheap plasma TV bought brand new can be found online at plasma god for around $450.

2nd place would be a LCD HDTV and is the most accepted in the high definition world. Even the best LCD TV can be found on the internet around $700 for 42 inches.

1st place would be..... LED TVs, they have all the benefits that LCD have plus the back-lighting is better and more energy efficient. Just an overall better picture. This comes at no big surprise that its better and more green so it cost a much more more money(just like everything else in the world). You can find 42-inch LED TVs online at Plasma God for around $950. Yup that's correct. Nearly over twice as much as a plasma television. Comes at no surprise most newer technologies in the electronics dept. are usually always more. So unfortunately the better TV's in this case our the more pricey ones. Which does make sense.
