Flat panel displays encompass a growing number of technologies enabling video displays that are lighter and much thinner than traditional television and video displays that use cathode ray tubes; they are usually less than 4 inches thick. They can be divided into two general categories; volatile or static.

Plasma and Lcd Televisions – Volatile

Volatile displays require constant power output to refresh the image on screen many times a second. The image appears steady because the images are refreshed more often than the human eye can perceive. Some examples of volatile flat panel displays are: plasma displays, liquid crystal displays, organic light-emitting displays, light-emitting diode displays, electroluminescent displays, surface-conduction electron-emitter displays, field emission displays, and nano-emissive displays.

Plasma and Lcd Television – Static

Static flat panel displays rely on materials whose color states are bistable. This means that the image they hold requires no energy to maintain, but instead requires energy to change. This results in a much more energy efficient display, but with a tendency towards slow refresh rates which are undesirable in an interactive display. Some examples of static flat panel displays are; electrophoretic displays, bichromal ball displays, interferometric modulator displays, cholesteric displays, and bistable nematic liquid crystal displays.

As far as viewing pleasure of Plasma and LCD television goes, you should choose plasma televisions which allow you to view them from all angles which is not the case with LCD televisions that bear flat screens and which means that the further removed you are from the screen, there is bound to be loss of brightness.

Pasma and Lcd Television – Myths

Myth # 1 – Plasma TVs emit dangerous radiation. Plasma TVs do generate a tiny amount of UV radiation, but its even less than typical tube-type TVs generate.
Myth # 2 – The gas in a plasma TV is poisonous.  The gas used in plasmas is a mix of two non-flammable “inert” gases; neon and xenon. These gases are not harmful, either individually or when combined.
Myth # 3 – Plasma TVs leak gas and require periodic “re-charging.” Each individual cell in a plasma panel is sealed, so a plasma TV will never require any re- filling or re-charging of its neon-xenon gas.

First and foremost before you cease reading, you should know that most people cannot tell the difference, physically, between LCD and plasma TVs. Most people can tell the difference immediately between a standard cathode-ray television and a flat screen television. The difference is in the size, but it is more than just the size of the screen. If a television is bulky, then chances are pretty high that it is a cathode-ray tv set. Without getting really technical, the inside of the cathode-ray screen resembles a glass science beaker laid on its side. The wide end is the part that you watch and electrons are funneled from the narrow end.

The main difference in LCD and plasma TVs is in how the picture is made. Plasma and LCD televisions both have exceptional quality. In the plasma, two sheets of glass are placed together and gas is pumped between the two. The particles are charged and give off green, red and blue phosphors. The phosphors make pixels which make up the picture. An LCD is two sheets of glass, but has liquid crystal instead. Rather than charging the particles, the crystal cells filter the colors.

So, which of the two are better? That is a matter of opinion but plasma flat screen televisions do suffer from excessive heat if left on too long and can have what is called a “screen burn.” A screen burn occurs when a static image is left on the screen for a long time and remains even when you change the channel. This can also easily happen with computer monitors.

If the confusing information did not daunt you and you kept reading, then you should know that LCD and plasma TVs are much better than the previous models of television sets. The slim design and space they utilize often make them worth the purchase. When you factor in the clear pictures and better quality, you quickly become sold on the idea of owning one. Whatever type you choose, compare the pictures and the costs before you make the purchase. If you check around the different retail stores, then you may be able to find a great deal.

Having a big television is not always what it is cracked up to be. Those big monstrosities that take up so much room but deliver horrible picture quality and sound are out. You need to get with the times and get yourself a plasma TV. There are plenty of plasma televisions to choose from. You can opt for a 42″ and hang it on your wall. You can have a 52″ that resonates with beautiful picture quality and sound.

A flat screen TV has many great factors that give it a supreme edge over the bulkier Cathode-ray televisions of the past. Besides a sharper image and better sound quality, there is also the fact that they are very slim and in some cases much lighter. If you do a comparison of the prices from today's plasma and LCD televisions, then you will discover that the costs are pretty affordable when you take into the consideration of the technology that you are getting.

You have probably noticed that flat screen monitors have been around for quite some time. The laptop would not have been a viable and streamlined monitor had it not been flat. Flat screen monitor’s first run of production were still quite heavy, but instead of a rounded screen, a flat screen was inserted. From that point on it was the primary goald of both engineers as well as designers to have a monitor that would weigh much less and not be as bulky.

You can thank your flat screen TV to the scientists at the University of Illinois. They were the ones to discover plasma technology. They wanted a different flat screen monitor that had a better picture quality. Back at that time monitors were simply television set that were utilized with the main computer. The picture was not very good. This technology was developed in 1964. Just think about the huge innovations that have occurred since that time.

Television has come so far from its humble beginnings. It was a novelty to possess something that could transmit a program from the other side of the country. Sure the image was grainy and in black and white, but it was still an item that only the wealthy possessed. Eventually it became more affordable. The television evolved into color and bigger screen sizes. At that point it starte to become quite a bit larger; as high as the average woman. It's sad that the image had lost quite a bit of it's vibrant color and also become distorted. LCD and plasma resolved these types of problem through going over from a cathode-ray (CRT) to the use of plasma.

People from all walks of life were getting into the hysteria of the flat screen TV. Even the price does not seem to be intimidating to most buyers when they compare the differences between their older models and the new fantastic versions. As more manufacturers discover new technology, the prices will fall. The 30 inch flat screen plasma or LCD can be purchased for around $800 and in some sales, they go for as little as $600.
