3D TV: Plasma or LCD?

While everyone is rushing to talk about 3D TVs. One important subject is often over looked when you buy tv looked and that’s 3D on what? 3D TV plasma or 3D LCD? You think theirs no difference? Well think again...

Plasma television may actually be better. Why? Especially considering how plasma television sales have dropped while LCD HDTV sales have soared? Well Plasma television have two big advantages when it comes to 3D. Those advantages are speed and contrast...

First, contrast. The eye receives high-quality when theirs a big visual difference between black and white. Its called a contrast ratio. Plasma's is almost always bigger than LCD HDTV, why? When a plasma television plasma television is black it's off, when LCD HDTV is black its because the tiny crystals on top of the always on black-light are blocking that light and sometimes a little light gets through. Even if LCD could go all the way to black as like Plasma. It cant do it as fast. Plasma can go to black 60 times faster then LCD. So that means that sports and games in 3D are measurable better.

As far as prices go, as mentioned earlier. Plasma television sales have been dropping recently compared to LCD and LED TVs. Due to demand issues this naturally will bring the price down. For example a basic 42-inch plasma television vs. a basic 42-inch LCD TV is around $500 vs $750(basic 2D) according to Plasma God online. Ironically its a win, win for plasma 3D vs LCD 3D, because its cheaper and has better quality of picture.

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.

The basics of 3D TVs

You've probably heard the rumors about 3D TV's and how it may dominate the television industry. Within the next 9 years one market research firm projects the 3D TV market is going to grow nearly 300 times. Meaning almost everybody may be watching, sports, movies, etc on a TV that seems to make the images leap off the screen

Before you get a 3D TV you should know more about it. For example: Do you need a new blue-ray player to watch 3D movies? YES. Is 3D a lot more expensive? No not really. Can you watch 2D television (normal quality). Yes you can switch back and forth from 2D to 3D.

A 3D display on a 2D surface is basically stereo for your eyes. One left image one right. In fact 3D video and pictures is sometimes taking using right and left lenses that are slightly off set. How offset? Exactly off set as a pair of human eyes. About 7 centimeters or 4 inches. Its called stereopsis. The brain thinks its looking at a 3d object because its seeing 2 different pictures, from 2 different prospectives. The same 2 viewing angels as your eyes. It creates the illusion of depth. Right now TV companies can project those 2 pictures on to 1 screen at the same time without making them blurry and its to expensive to have 2 different TVs for each eye. So they came up with 2 main ways to trick your brain into seeing focused 3D pictures on 1 screen.

3D TVs currently falls into 2 different categories. 3D you watch with active shutter glasses and 3D TV you watch with polarized glasses.

Here's how active shutter works. The glasses are powered by batteries and our linked to an emitter tin your 3D television. The emitter sends radio or info-red signals to your glasses and tells each lens of the glasses to either open or close. Like a window shutter. This happens in-sync with fast flashing left or right images on the screen. This all happens over 100 times a second. This is why its nearly impossible to turn your LED TVs or a Plasma television into 3D. This refresh rate is also known as the HZ.

OK so you know about active shutter glasses, but that's not the only way to see 3D. If you've seen avatar or Alice in wonderland in the movie theater you were using polarized glasses. Like shutter glasses. Polarized lenses lets you see different slightly off-set images in each eye./ Tricking your brain into seeing 3D, but instead of flashing left and right pictures one at a time on the screen. Movie theaters project both left and right images at the same time with 2 different projectors. Its not blurry because the left lens only lets your left eye see only the left the left picture and the right lens only lets your eye see the right picture and remember polarized lens dont need to be battery powered or synchronized there passive.

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.

LED TVs vs. Plasma Television

New members have joined the TV family, as well as Plasma and LCD. We now have LED back light TV. LED back light TVs which the industry is simple calling LED TVs.

LED TVs has 3 main advantages were not going to give you a science lesson about the technology. LED TVs are known for having depth, color and energy efficiency. Compare to LCD and plasma TV's. LED TVs are known to have whiter whites and deeper blacks. This is also called ratio and you'll often see this listed as a feature on TV's. Basically the higher the ratio the better the contrast so the better the picture. 2nd LED TVs are really slim. LCD TVs cannot hold a candle to LED TVs in regards to its thinness. LCD televisions are usually twice as big as a LED. 3rd, LED TVs work different from Plasma and LCD TVs. They use a lot less electricity which will save you money and help you be more green. And the final benefit to having a LED TV. you can watch your LED TV from almost any angle in the room and unlike plasma and LCD the color wont be darker...

Plasma television will give you a bright detail picture. Plasma television has a slim design (not as slim as LED though) that allows you to put on a stand or hang on a wall. Plasma televisions are known for there smooth motion, rich colors and impressive contrast levels.

If your considering a plasma television there's two things to remember. First plasma's our not available in smaller screen sizes. Just 42 inches or larger. So a cheap plasma TV is usually around $600 or less. Therefore there not ideal for small rooms like a kitchen. 2nd, Plasma TVs will reflect room light more so then other TVs. If you have a room with a lot of lamps and windows. Then you might want to go with a led TV.

So how do you choose between a LED TV or a plasma television? Well for a cinema like experence in a dark room. Then you'll appreciate plasmas fluid motion and true to life colors. If you looking for a TV under 42 inches then LED TVs are right for you. They have brighter whites and deeper blacks, but overall Plasma televsions are way cheaper in price.

Plasma Television vs. LED TVs

For along time There has been popular discussion of Plasma TV vs LCD TV. back when LCD and Plasma were born one of the most popular discussions in the TV industry is Plasma vs LCD. In the 5 years since both have been in the marketplace you would think the answer would be clearly defined, but it's a bit more complicated then that.

We'll begin with the comparisons of the two technologies. We'll begin with plasma television. Plasma television has hundreds of thousands of gas cells that are brought together to make an image. On the other hand LCD or liquid crystal display uses "glass sandwiches" of liquid crystal. Images created by varying the amount of electrical charge applied to the crystals. Then the screen is lit behind by a series of LED's or florescent tubes. This is because the differences between the technologies. For example if a plasma cell is off Its not lit up meaning more blacks, while a LCD pixel is still lit from behind even when its displaying black. Though LCD backlighting has got better, plasma television has stayed 1 step ahead. Even with the best LCD TV 55 inch screens we've been able to see some fantastic results for LCD HDTV, but without debate plasma TV is still better. The disadvantadge, the motion blower are the biggest one. It lags when LCD pixels are turned off and on. Some LCD HDTV are down to 5 milliseconds but none-the-less it can still lead to a blur in motion. Plasma TV has the lexury of not having to worry about this, not to mention the black level issue

Plasma TVs have a good reputation of creating what appears to be a "film like picture". but this doesn't mean you have to go the whole 9 yards for cinema quality. currently 1080p has be on hit plasma tvs in a large way but the number is growing. Many customers have complained about the "burn in effect" though. This happens when a screen broadcast the same image for a extended period of time and the picture is permanently burned in on the screen. For Plasma televisions this does not mean it will last forever and will eventually go away. Finding a cheap plasma television is not difficult, but you may want to consider the prices vs LCD

Even with HD being the "cool thing for 2010 there still is very little content for 1080p. Even when compared to the thousands of television programs and DVD's. 1080p means 1920 by 1080 pixels and is the best high qualitiy resolution money can buy. You may gain some piece of mind now to buy a 1080p television. However you may not be getting the best picture. Its not all about the resolution.

Other qualities to look for would include 100 hertz. This in fact removes the awful jittery picture from movies and over-seas television shows. To get the most out of HD disk you'd want something called 24P.

Still confused? The only person who can make a decision as to buy a television is you. Try and view as many TV's viewing the same footage as you can. Try going to your nearest local best buy, wal-mart or any outlet store where they have the same video displayed upon dozens of televisions. After choosing the right tv for you. Go online to Plasma God and search for the exact same TV. 9 out of 10 times Plasma God is the cheapest.
