The plasma TV has been with us for some time now and is preferred by many homeowners. However with industry experts surmising that LCD televisions will be more widespread in the future due to energy efficiency problems with plasma TVs, the time has come for consumers to decide which option to take. Plasma or LCD TV, which is the better choice?

Plasma and LCD TV models look almost identical, both are flat, elegant and typically both offer a stunningly sharp and clear picture. There are however fundamental differences between the two technologies. In terms of the improvements from the older, CRT televisions both plasma and LCD models are clearer, they have a style about them that fits into modern living, most have a wide viewing angle and as they are wall mountable they are a brilliant space saving option. Additionally as both varieties are widescreen, they allow the viewer to watch movies how they were supposed to be seen, in the perfect aspect ratio.

The LCD TV works using a liquid crystal display. This put simply is hundreds of thousands of tiny pixels that each change colour and shade to create an overall image. Behind is a backlight that gives the image its brightness and as electronic current is passed through the device, the pixels change rapidly to formulate moving images.

The plasma TV on the other hand is constructed of two sheets of glass, with the gap filled with xenon or neon gas. Behind this screen sits phosphors for each primary colour, as electricity hits xenon it produces UV light that in turn hits the phosphors so they change colour rapidly and hence create an image. This process is far more wasteful than LCD and hence uses more power.

Naturally each type of TV has various benefits and disadvantages, the following will put forward a seven step process to assessing the differences between plasma and LCD.

The first category is size and weight. Typically plasma televisions are available in larger screen sizes, in fact up to around 71 inches, they are however normally heavier than LCD models. In comparison LCD devices are normally smaller, around a 42 inch maximum although this likely to increase in the future.

In terms of picture quality there is not much to split the two; however LCD screens normally have a higher resolution in smaller sizes. One problem that occurs with plasma TV models is image burn. This means that after a long period the screen shows a residual image, typically a network logo. This does not happen with LCD screens.

Viewing angle is generally better with plasma although with the more recent LCD models this is less of an issue, both have a viewing angle of around 160 degrees. Brightness is generally better with plasma TVs although on the other hand LCD screens have less glare and are hence better for bright rooms and environments.

Both TVs have a lifespan of around sixty thousand hours meaning that if the television was left on continuously it would work for almost seven years. Energy efficiency can be a problem with some plasma models and has become a major issue in recent months with technology companies focussing on efficiency as eco laws start to take effect.

Hopefully this article has highlighted the common differences between the plasma and LCD TV. Seemingly the growing trend is for LCD models due to energy efficiency issues; ultimately the choice comes down to personal preference.

Digital signage is now the new must-have marketing tool with its applications and uses having multiplied many-fold over the last few years with LCD and plasma screens now being seen in all manner of locations for all manner of uses.

One of the latest environments to be exploited for the purposes of digital advertising is the use of plasma and LCD screens outside.

Digital outdoor signage is one of the few niche areas left in the digital marketing industry but more and more companies have spotted the potential and are producing LCD TVs that can be situated outdoors.

The major challenge of outdoor digital signage is protecting the plasma or LCD display from the elements. Many manufacturers ensure their outdoor LCD or plasma is sealed to protect from the rain which is obviously highly important when it comes to outdoor signage. However, many of these outdoor LCD screens are manufactured for mild climates and little consideration is given to the varying extremes of temperature often found in Europe and North America.

Extreme heat in the summer can be extremely damaging to an LCD. Both the screen and the electronics of the LCD need to be protected from the sun. LCD screens are easily damaged by direct sunlight while without adequate cooling exposure to high temperatures will dramatically shorten an LCD or plasma’s lifespan.

Likewise protection from the cold is highly important as most LCD’s will simply not be able to cope in temperatures below zero.

However, many manufacturers are starting to identify these outdoor hazards and are producing LCD’s designed to operate in extreme temperatures. However, most of these outdoor digital signage solutions are targeted at a particular environment such as extreme cold or extreme heat. There are very few options available that can actually deal with the heat of summer and the freezing temperatures often endured in parts of America and Europe during the winter months.

Fortunately, for those of us that live in areas where both extremes of temperatures are often experienced throughout the year a smarter more practical solution is to use standard LCD displays and house them in an outdoor LCD enclosure. LCD enclosures (and plasma enclosures) are now manufactured by some industrial computer enclosure manufacturers who use their experience of housing computers and touch screens in industrial areas to build LCD enclosures that can cope with not just the rain but all extremes of temperature and weather.

These steel LCD enclosures are also built to withstand vandalism and theft allowing the outdoor digital signage to be left unattended with full peace of mind.

your biggest thing to consider when purchasing a television was the size of the television. This was usually determined by your budget and . When those needs were the project was trouble-free. Purchasing a TV in the present market is a much more complex task: there are LCDs, Plasmas, and projectors to decide from. Ahead of a purchase can be completed, to begin with you must recognize what your options are as well as how they match against each other.

LCD TVs and Plasmas operate differently to achieve the same required effect: providing a sharp, clear, highly responsive image. lcd television have crystal cells that tighten and unwind appropriately as they are sparked via an electronic signal. A intense backlight suffuses the cells and as they rotate they sort out all the colours in the spectrum except for the required one. Plasma televisions have millions of pixels that, once activated, release gases that work to produce a certain colour in the red, blue and green bands enclosed within the pixels.

Until recently Plasma screens were notably superior a variety of views. Because of the winding and unwinding activity of the cells in LCD televisions, sharp moving video, specially sports and action films, frequently show a trailing appearance as the images changed and moved. Plasma screens do not do this because every pixels is activated individually. Plasmas produce undistorted imagery at sharply-angled viewpoints, unlike LCDs, whose images can appear fairly corrupted when viewed at similar angles. Plasma screens also exposed much deeper colours than LCD televisions, with particularly deep blacks.

Enhancements and upgrades in the LCD design have allowed it to match Plasmas in zones that it had shown deficiencies. lcd television also have many obvious benefits over Plasmas. Plasma televisions may have at first been able to show off the largest screens, but they by no means have the smallest. LCD screens now have screen sizes that can virtually match the biggest plasma televisions, and they can be produced so small that they equip a lot of telephones. They’re also more portable. Plasmas are awfully heavy and normally thicker televisions, which makes it not easy to move them. They also can’t be mounted to weaker ceilings or walls due to their weight.

Plasma TVs do have disadvantages. As they contain gases, they are also affected by air pressure. As a result they don’t act as effectively at high altitudes. lcd television, though, are not affected by this. As a result, they’re used in generally all airlines and are favored in a lot of high cities. Plasma TVs what’s more experience a burn-in effect, which happens if a still image is left on the screen for a long period of time. This can come about when a movie or game is left on pause for an extended period of time, or if the panel is being used to transmit computer imagery. Subject to the extent of time the image is left on the screen, the burn-in can be serious and permanent.

LCD televisions are steadily becoming the obvious choice. The crucial issue to most customers, the cost, has smoothed out so that Plasma panels aren’t the guaranteed best-buy. The enhancements to the technology and the price have let LCD televisions to turn into the dominant format in the television market.

lcd television are improving and evolving central in every dimension – factually: they are at this moment starting to put forward 3D screens. Furthermore, they can work much longer than Plasma television screens. Even though they have a tendency to be rated for equal lifespans, the end of the Plasma television’s lifespan highlights the aspect at which it is partially as bright as it at first was, whereas the projected end of an LCD screen’s life is marked by the point when the backlight burns out. At these points a Plasma television will continue fading until the image is no longer visible, while the LCD panel’s backlight can be replaced.

And if you are not doing a Powerpoint presentation in multiple areas, projectors are no way as good as LCDs.
