The slim and thin plasma TV sets have become desired products worldwide. Learn the basics of how the plasma technology works.

Television technology for the past 75 years has been based on the technology of CRT or cathode-ray-tube. In it there are guns that fire beams of electrons, which are particles that are negatively charged inside a tube, made of glass. These electrons cause excitement in phosphor atoms located at the screen end or the end gets lighted up. The phosphor coating being lighted up on different areas with various colours with dissimilar intensities produces the image on the screen.

The images are sharp and vibrant but the sets are bulky. Thus a big screen will result in a television set that will take up a good size of the room! With necessity being the mother of invention, this difficulty has led to the popping up of a new technology leading to plasma flat panels for display. These sets have wide screen but are only a few inches thick.

A video signal lights up thousands of dots inside the monitor or television. These dots are known as pixels having highly energized electron beams. Usually pixels have three colours – blue, red and green. These are evenly spread out across the screen. Combining these basic colours in different proportions produces the entire colour show. The fundamental idea of the plasma unit is to light up minute coloured lights that are fluorescent to create the image. Each pixel comprises of three of these lights – red, green and blue. Similar to the CRT, the plasma television alters the intensity of the various lights to bring about the effect of the full spectrum of colours.

The first generation of plasma displays did not have tuners that receive the television signal and interprets that to make a video image. But today digital tuners have been assembled to the main unit.

Plasma is the central element in the fluorescent light. It is a gas that has free flowing ions and electrons. Ions are atoms that have been electrically charged and electrons are particles that have been negatively charged. Normally a gas is made of uncharged particles. Thus a gas atom usually has equal number of protons and electrons atom resulting in zero total charge. But the scene rapidly changes with the introduction of free electrons in the gas. This leads to the setting up across it of electrical voltage.

Free electrons clash with the atoms dislodging other electrons. When an electron goes missing the atom loses its balances. It becomes and ion. In the case of plasma there is electric current passing through. This causes particles that are negatively charged to rush to that region of the plasma that is positively charged; on the reverse the particles, which are positively, charged hurry towards the area that is negatively charged.

There is a mad rush and one collides into another constantly. The gas atoms in the plasma get excited. Photons of energy are now released. The atoms used in plasma displays are neon and xenon atoms. The gases of these are contained in thousands of tiny cells sandwiched between two glass plates.

Thus to sum up we find that the Plasma TV forms a picture from plasma or gas that is filled with atoms of xenon and neon as well as innumerable electrically charged electrons and atoms that bump and collide to release energy or power. The net result is that without extra bulk, the viewing area gets enlarged. Rather than being fat the Plasma TV is slim and thin. The quality of picture is par excellence but the draw back is that the cost is beyond the reach of many people.

CD TVs are incredibly popular, and prices continue to fall year after year. Yet they’re still relatively expensive – you can still expect to pay between $1,000 and $3,000 for many of the high-tech models with large screen sizes. If your goal is to find an LCD TV sale, you’re in luck: increased competition in the LCD TV market has created a number of avenues for finding an LCD TV sale or for finding LCD TVs on sale. Let’s look at a few of the ways you can find a bargain at an LCD TV sale.

The first major source for an LCD TV sale is through online discounters. Online discounters tend to offer lower prices than even the discount electronics stores like Best Buy and Circuit City because they have much lower overhead – they don’t have to pay for retail outlets and for distribution to those outlets. Keep in mind, though, that the total cost of the TV can be higher than its purchase price due to shipping costs. Some TVs bought at an online TV sale are sold with free shipping; in other cases shipping can cost $40 to $80 and up depending on the size of the TV you purchase. You can also find an LCD TV ’sale’ at auction sites like eBay – not only can you find a new LCD TV, but you may find a used model that’s perfect for your viewing habits and your pocketbook.

Speaking of a used LCD TV, check out a used LCD TV sale. ‘Used’ doesn’t always have to mean ‘old.’ Many retailers take TVs in trade from their customers, and they’ll sell you a used set at a greatly reduced price. Why? LCD technology is rapidly advancing and today’s cutting-edge model can be tomorrow’s out of date model. Many consumers love to buy the latest technology, and will sell their ‘old’ set at a fraction of its original cost… letting you get a great buy at a used LCD TV sale. Some electronics stores take trade-ins and return the used model to the manufacturer for inspection and testing before they re-sell it. You can find a used LCD TV sale by checking with your local electronics stores or by checking online auction sites.

Another type of TV that’s always on sale is a ’scratch and dent’ TV. Retailers always offer their slightly damaged LCD TVs at a sale price. Why? Just like other appliances and electronics equipment, an LCD TV can’t be advertised and sold in new condition if it has minor cosmetic damage. Most retailers will discount those items heavily instead of paying the shipping charges necessary to return them to the manufacturer for repair. When you walk in the door, the scratch and dent items will always be included in an LCD TV sale. Best of all, most scratch and dent TVs come with a full warranty, so you won’t have to worry about reliability. You can buy an LCD TV on sale by finding a unit you want with minor cosmetic damage.

Discontinued models are frequently included in an LCD TV sale. Manufacturers constantly seek to introduce new models with cutting edge technology, and retailers sell overstock and discontinued models at near-cost levels to free up inventory (and cash.) A discontinued model is frequently one of the feature products in an LCD TV sale. Keep an eye out for seasonal specials, too – shopping in January will often let you take advantage of excess inventory in the post-Christmas period.

Finally, you can create your own LCD TV sale by taking advantage of rebates. Some rebates are advertised at the point of purchase; others are a little more ‘hidden,’ and can only be found by checking with the manufacturer. Many electronics manufacturers, like Sony, post rebate information on their website. While your local retailer might not have the latest rebate information, the manufacturer will – and if you take advantage of a rebate, you’ve created your own LCD TV sale.
