How Do Plasma Televisions Work?

Plasma TVs have been one of the most popular home entertainment solutions on the market for several years. They offer outstanding resolution and a quality picture and are usually capable of displaying HDTV signals, allowing you to watch all of your favourite HDTV programs. Compared to rear projection TVs, plasma technology offers some of the best viewing angles- no need to fight over the best seat anymore- and offer uniform screen brightness.

But how does plasma technology work? It’s pretty simple. Some form of inert gas- say Xenon, for example, is inserted between two plates, which are held together, between which are over two million pixels, capable of producing a mind-boggling array of colors. The gas is then energized by a charge which turns it into a viscous substance, creating an ultraviolet light, which allows each pixel to display the appropriate color. Unlike rear-projection TVs, each pixel in a plasma display contains red, blue, and green phosphors, there is no need for a cathode-ray tube. In traditional TVs, the cathode-ray tube, or CRT, fires electrodes to the screen, where they excite phosphor atoms causing them to light up, thus creating a picture. The CRT is bulky and is responsible for the box-shape of traditional televisions. For example, if you want to increase the size of the screen in a CRT, you must also create a larger cathode-ray tube, therefore making the whole TV that much bigger- and bulky.

One drawback to plasma technology is the inability to recharge each individual pixel. Each pixel is an independently sealed entity, as is the plasma display panel and the gas, so if a pixel, or a group of pixels, fail or darken, the entire panel unit must be replaced.

Fortunately, however, you can expect your plasma display to last at least 60,000 hours of playing time, before the pixels begin to darken. So, in layman’s terms, if you watch your TV for four hours a day, you can expect the panel to last around eighteen years.

Plasma technology has greatly increased the quality of home entertainment, ushering in a new era of television technology.

Flat Screen TV Comparison: Plasma vs LCD

>

Flat screen TV is one of the most popular and exciting TV technologies today. At only a few inches thick, flat screen TVs offer unparalleled flexibility and convenience. Older conventional TV’s, in fairness to them, did offer crisp and vibrant images. However, these TV’s, which operate through a cathode ray tube (CRT), suffered from one major drawback, they were bulky. As screen size increased, so did the bulk and weight. However, the TV of old has reached its twilight years. New television technologies have enabled TV manufacturers to create TVs with wider screen size yet still only a few inches thick. Thus, flat screen TVs usher home entertainment into the 21st century.

Flat Screen TV basically refers to two technologies: Plasma and LCD. The advances in these two technologies have enabled TV makers to build thin, lightweight TV screens with a large picture area. Plasma and LCD both offer similarly large, lightweight, flat screen TV’s but the similarities are skin deep for their inner workings are different.

Plasma or LCD?

Plasma and LCD TVs generally look similar however they use very different technologies. Plasma utilizes a grid of tiny cells of gas plasma that light up and create a picture when charged by precise electrical voltages. LCD (liquid crystal display) screens on the other hand are made of liquid crystals sandwiched between two glass plates and create images by varying the amount of electrical charge applied to the crystals. Both Plasma and LCD offer excellent picture quality. The following are their strengths and weaknesses and edge over the other.

1. Plasma screens can display blacks more accurately compared to LCD. Thus, pictures in a Plasma TV have richer contrast and better detail especially in dark TV and movie scenes. LCD TV’s are catching up however.
2. Plasma TV has better viewing angles than LCD TV. How far you can sit on either side of the screen before the qualities of the pictures are affected is what the “viewing angle” is. In LCD TVs, brightness and color tend to shift when angled too far while that of Plasma TVs remain solid.
3. Plasma TV can produce brighter color while light leakages in LCD screens affect the color saturation.
4. Plasma TVs are priced relatively less than their LCD counterparts especially in the large screen segment. Plasma TVs offer much larger sizes than LCDs, yet are still priced lower.
5. LCD has a higher native resolution than plasma TVs of the same size. This results to sharper images and makes LCD TV the better choice for HDTV.
6. LCD TVs consume almost 30% less power than Plasma TVs.
7. LCD TVs are generally lighter than similar sized Plasmas.
8. Among the two, LCD screens have a longer life span than plasma screens. LCDs can last up to 60,000 hours compared to Plasma that average from 30,000 to 60,000 hours.
9. Plasma TVs are more prone to screen burn-ins compared to LCDs although newer plasma technology are less susceptible to these.

If you are looking for a large flat screen TV, Plasma TV is recommended. Plasma TVs can give you better value for your money. The price difference between Plasma TVs and LCD TVs is big. However, if you have money to burn, then LCD TV is the better choice especially if you want the sharpest images. For smaller flat screen TVs at the range of 15″ to 36″, LCD is the way to go. Ultimately, both technologies are still evolving and new innovations and improvements are definitely in the works.

How to buy a plasma television set

Most people think that all you have to do to purchase a new plasma television set is to walk into a shop, look around, and purchase the first set that catches your attention. This is how you’re supposed to do it, right? Wrong! Buying a television, whether it has a plasma monitor or a LCD monitor, takes careful planning.

The first step in finding your dream plasma television set is to measure the space where you plan to put it. This will help you to decide which size set to buy and will also help to guide your budget. Remember to measure your car, too- there’s nothing more frustrating than picking out and purchasing that perfect plasma television set, if you can’t fit it into the car to get it home!

If you’re going to splash out and completely redecorate your home entertainment room, you should think about contacting a home installer, to get some tips and ideas before contracting the work. Remember to take into consideration things which might affect your view of the TV, such as lighting, windows, and other parts of the room which could possibly cause a reflection or obstruction of the display.

Once you’ve thought about where you’re going to put your new plasma television set- and how you’re going to get it home- you now need to think about what sort accessories you’ll need. Will you be using it in conjunction with your camcorder? Will you need to purchase a set of external speakers, or will you be hooking the television set up to your stereo? If so, remember to check that the monitor or set has an AV-hook up. Having the hook up in the front of the TV will make it more convenient to attach your camcorder or gaming system.

Finally, you should consider the television set’s overall picture quality and ease of use. Take the time to sit and watch the set in the store, to get an idea of how you’ll feel watching it at home.

With a little preparation, you’ll find the plasma TV set that is just right for you and your home.
