Plasma TV

The plasma television is a relatively new type of television, with a flat screen display. It works by having a mixture of different noble gases in small compartments behind a panel of glass. The plasma TV derives its name from the reaction in which these noble gases are turned into plasma, which emits light and forms the display you see. Plasma TV’s are often compared to LCD’s (liquid crystal displays), another type of flat screen television that uses liquid crystals in front of backlighting or fluorescent tubes to produce images.

Plasma televisions (and flat screen TVs in general) are extremely easy to handle. Due to their very nature, plasmas are flatter than traditional televisions (also called CRTs) and thus, are lighter as well. Currently averaging 5 inches in width and 100 pounds, their size will soon be reduced to an inch in width and 45 pounds. This lack of bulk has heralded in a new era of television placement; consumers can now mount their plasmas on the wall without worrying about ruining the wall.

Flat panel TV’s, like plasmas, also have a higher resolution than traditional tube televisions. Resolution is related to how many pixels there are in a square inch; the more pixels, the higher the resolution. At present, high-definition plasmas have resolutions that vary from 1024×768 (720p) to 1920×1080 (1080i), which is much higher than the maximum resolution for tube TVs-480 lines.

Flat screen televisions also have a longer life span than CRT televisions. Most plasma manufacturers now assert that their televisions have a life span of up to 60,000 hours, where CRT televisions have a life span of at least 5 years. Assuming that a consumer watches 3 hours of television a day, a plasma TV can last up to 55 years!

Plasma televisions have both a better color ratio and more contrast than LCDs. For plasma TVs, each pixel can virtually be turned off to produce truer blacks. However, LCDs use a backlight, which will shine through the “black” pixel and damage the contrast quality. CRT televisions have the best contrast, but both plasmas and LCDs surpass them when it comes to color reproduction.

Plasmas also have a wider viewing angle than LCDs. When viewing the television from the side, higher above, or lying on the floor, plasmas retain their crystal clear picture much better than LCDs do. Due to the shutter effect caused by the backlighting on LCDs, the larger the viewing angle is, the more brightness variation an LCD television viewer will experience.

Plasma TVs have been criticized because of the possibility of burn-in images. The burn-in effect happens when a still image is shown on the plasma’s screen for long periods of time (for example, when a DVD is paused and the plasma is left on, burn-in might occur). A ghost of the image may remain on the screen after the image has been changed. However, this effect has almost been negated in the newer models of plasma televisions.

Plasmas also have virtually no size limitations; depending on a consumer’s budget, plasma screens can go up to any size. LCD and CRT televisions, on the other hand, are confined to approximately 40 inches diagonal.

The demand of plasma TV’s have gone up considerably since its launch in the market. There are many makers of plasma televisions and each and every brand is competing against each other to bring out the best. These TV’s are high in demand and are getting better with every new technological invention. If we take a close look at the market the plasma TV’s that are very high in demand are the ones that are most popular and of course highest rated amongst consumers.

As it is there are so many brands competing against each other and plasma televisions has serious competition from LCD TV’s too. A plasma Television looks really elegant in a living room. A plasma television can be mounted on a wall and it can be matched with the interiors. The technology used in making plasma television helps in better resolution and a defined picture quality. We can compare the screen size and make a purchase. The latest features in a plasma television does not mean that it is the best but we must make sure that the TV is in good condition and fits our bill. In fact the latest in the plasma TVs range is the 3D plasma TV but before we get a positive review from the market.

We can get a plasma television in the living room, bedroom or the kitchen but we must have that amount of space so that to place the TV and have enough space for ventilation too. Most companies offer the same features and the same sizes for plasma TV’s but the technological factor and the price is the main differentiators for the different brands of plasma TV’s. One disadvantage of plasma TV is that they consume a lot of power and electricity so if we are making a purchase we must make sure we can afford the rise in the electricity bill.

Most brands have slashed their prices since its launch. Initially they were regarded very expensive but now they have become affordable but again the common man still is far behind from having one in his living room. Different companies have different schemes and prices. Some have low features and are priced moderately whereas for some companies the features are also good and the price is easy on the pockets too. Some companies offer easy installments so that we can afford a plasma televisions. Some companies have very high priced TV’s but the features are really poor.

Before we buy or boil down to one brand of plasma television we must make sure that we have analyzed that brand carefully, that it is a good brand, easy on the pocket and that we can take pride in it. Market analysis is very important step. There are so many brands, some good ones some fake. Fake products do not last and we will lose our money too. so we must be extra careful with fake products. Plasma televisions is an expensive purchase so we must make a decision carefully. A highest rated product by the company does not men it is really good. We must do our homework before we make a purchase because we are investing in it and we are the ones that will take pride in the product. So go ahead and buy that plasma TV that you think is right for you.

When a manufacturer for any product wants to showcase their products and services to new potential customers, the best option is to display the product range to the new buyers, whilst they are touring the factory. ? Now there are several problems with this, as you want to give the impression of a forward thinking company and that the production area is open planned, this allows for ease of control. ?

Now the easiest way to create some basic digital media content, is to use a software package that includes Flash, this will enable you to drag and drop images from your computer into the program and then you save it as a flash file. Then all you need to do is upload it to the media server and then set the signage software to run as you wish, setting the rotate time, etc. ? Some production areas however are extremely hostile, with fluid, coolant and dust present, any one of these can make a standard Plasma or LCD display fail, not forgetting the small factor PC or the media player.?

For dusty applications, an IP56 Plasma enclosure is required, these protect from dust ingress as well as fluid splashes, an IP65 plasma TV enclosure offers a waterproof solution, well these units are designed to be washed down with high pressure water jets, ensuring the electronics inside remain dry and safe. ? An IP65 TV case is the equivalent of a NEMA 4X, this is the American standard, compared to the European IP standards. ?

The IP65 or NEMA 4X can also accommodate plasma televisions outdoors, providing an ideal solution for the factory and for the garden. Once the display is mounted on the internal mounting frame that can be tilted for optimum control, the front access door is then locked. The outdoor television is viewed through a optical quality, anti vandal material, that also is none reflective. So these units will protect from abuse on factory production line or potential robbery. ?

Once installed, a good quality plasma enclosure will last for a minimum of 7 years, providing security and protecting the precious display and computer housed inside.
