The larger the screen the more impressed the audience will be, this is why large screen advertising is starting to grow into an Industry all on it's own.

We have been involved in out of home digital signage for a number of years and in the past quarter we have noticed a massive increase in demand for big screen TV's for capturing the attention of potential consumers and marketing to them.

Now the problem lies with a large screen TV, is that the television display is likely to be expensive, for example Mitsubishi offers a 65" display for $6,000 this is no means the most expensive display available, so when you deploy a screen of this value you have to look at protecting it from theft, vandalism and of course the weather.

This big screen TV cabinet are normally supplied with an internal mounting frame for the TV that has special security fasteners preventing anyone without the special tool removing it. Some outdoor TV cabinets have been supplied with webcams that record anyone who comes close to the display, this way should anything un-towards happen to the display there is a record and am image that can be used in court to prosecute the individual responsible.

Another issue is the mounting of the big screen, as you need a structure that is strong enough to support it once fastened into position. You have to decide if you wish to mount the TV direct to the wall, or from the ceiling or floor. However which ever you choose, you have to ensure that the mounting frame can support both the TV and the big screen TV cabinet with a total weight of around 200lbs.

There are many technologies emerging in display devices like TVs. Every technology excels in particular feature of display and has particular method of display. Different technologies used in TVs are:

LCD TV:

LCD (Liquid Crystal Display) televisions are thinner and lighter and provide much sharper and clearer picture than CRTs of similar size. They are ideally used for cell phone displays, computer monitors, and to view still images. LCD TVs have a flat screen so there will be no picture distortion and don't have screen "burn in" like curved tube TVs. In general, LCD viewing angle is 175 degrees. The picture can be viewed 87 degrees from each side. LCD TVs are very economical to use and screens less than 35 are fairly inexpensive. LCD TVs are backlit and blocks outside light. So, they are suitable for natural lighting situations. Most LCD TVs have a half lifespan (50% of original brightness) of over 30,000 hours (16 years of viewing at 6 hours per day). LCD sizes generally range from 13 to 65 but some manufacturer will offer up to 100 sizes.

Plasma TV:

A Plasma Display Panel (PDP) is a flat panel display used in large TV displays. They have better and accurate color generation than LCDs, and with far display, wider viewing angles, and do not experience degradation at high angles compared to LCD. Plasma displays are ideal for viewing motion video in large displays.

· Plasma screen sizes generally ranges from 32 to 84 but some offer screen sizes up to 100.
· Plasma pixel, technology provides a brighter picture with more contrast between the blacks and whites than standard TV.
· In general, plasma TVs viewing angle is 160 to 180 degrees and picture can be viewed from any angle.
· On an average, Plasma TVs have a half lifespan (50% of brightness) of 50,000 to 70,000 hours (20 years of viewing 6 hours a day to 50,000 hours).
Some plasma TVs are provided with upgradeable video cards that helps to match with future technology.

HDTV:

HDTV or High-Definition Television is a digital television broadcasting system offering a higher resolution compared to regular television systems. HDTV is digitally broadcast unlike earlier analog broadcasting, because digital television (DTV) signals require reduced bandwidth because of digital video compression.

HDTV will not have standard TV problems, like low quality sharpness, troubles with brightness or contrast, spots, other visual, or audio imperfections, problems like double images (ghosting), and weak signals. HD television provides clearer pictures with excellent sound quality, a wider viewing screen and up-to-date scanning. HDTV will provide more and superior channels provided by regular satellite or cable television with theater system experience.

LED TV:

LED (Light Emitting Diode) TV is an LCD TV that uses LEDs for back lighting, instead of using the fluorescent lights (as it creates more black spots). They are ideally used for low-energy indicators, as substitutes for traditional light sources in general lighting and automotive lighting.
· LED TV currently costs more than a standard LCD or plasma TV.
· LED TV has got great looks and very easy to Install.
· Edge-lit LED television will consume 30-40% of less power than LCD or plasma TV. But backlit LEDs will consume more power.
· Brighter picture can be viewed with LED television compared to a standard LCD TV.
· LED TV that is backlit, with local dimming and RGB LEDs, will have an enhanced picture and better contrast ratio and colour accuracy compared to standard LCD TV.
It has a long lasting life and also eco friendly.

OLED TVs:

OLED (Organic Light Emitting Diode) TVs depend on light emitting polymer technology. Its features including,
· In OLED TVs, there is no need for backlights or extra heaters or coolers, so there is less power consumption.
· As OLED materials has the capacity to support full spectrum of visible light, so there will be higher contrast and it has high-speed refresh rates.
· OLEDs are much faster than LCDs. Fast motion and quick eye movement pictures are more realistic. And OLED TVs will make virtual images to look realistic and can be viewed easily for longer periods.
· It has larger viewing angle and for near-eye applications, it provides more pleasant viewing without distortion.
One disadvantage with OLED TVs is the limited lifespan of the organic materials used in its manufacturing. In addition, blue light degrades quickly with a lifespan of 14,000 hours (when used 8 hours per day for five years) on flat-panel displays.

If you have looked at all the fabulous photos of an LED TV from this year's catalogues and are set to buy one for yourself, it will really be helpful in your purchase if you know a few facts about the technology first. The LED TV had a great reception at this year's CES Trade Show and Samsung was the first one to actually have brought the technology into the market with its Samsung 7000 television set range.

Simply put an LED TV is actually an LCD television which incorporates an additional technology. LEDs are light emitting diodes which are an efficient light source and while previously other methods of lighting up the LCD screen were used such as fluorescent tubes, now the LEDs are utilized to light up the LCD display.

While fluorescent tubes provide light, they have a few drawbacks. They take up more space and are heavy in weight. Also they do not provide sufficient color quality because the blacks displayed are not true blacks and this reduces the vibrancy of all other colors. This is basically why the LED technology came along - so they could provide a lighting source that can show the purest blacks and whites.

At the present there are a couple of LED TVs available to the consumer. One of them is back-lit model which allows the LCD display to be lit up by back lighting through a number of LEDs placed behind the television panel. The other one is the break through edge lit version which uses LEDs as a light source positioned around the edges of the television screen. Using LEDs as back lights requires a lot of space in the back of the television set, making the LED TV thicker in size. The edge lit LED display however, requires less back panel space and hence the designs are much slimmer and sleek.

Another useful feature of the edge lit LED television is that it consumes less energy which is not only good for the environment but also saves you on the monthly electric bill. So the first thing you will need to do when buying the LED TV is to figure out whether you want it back lit or edge lit, since the rear lit ones will be more expensive to buy. There are also a number of accessory options for the LED television sets.

The television screen can be used as an interface for one's personal computer. This makes for a television set that can play all your favorite items from your computer which includes live streaming from any internet website and watching online movies. You can even watch your home videos that have been saved on the computer. LED television sets also come with a USB port which can be used to view the material on your USB flash drive and view movies, videos or pictures.

Other accessories that can be added to the LED TV are Blu-Ray players, satellite dish receivers and even the latest gaming consoles. This is owing to the HDMI ports which eliminate the need for cables (both A/V and coaxial) and adapters. You can also buy a wall mount kit with your LED if you are interested in mounting the set on a wall in your home. LED TV sets are much lighter than the previous LCD TVs and they are much easier to hang on walls. This is especially true for the edge lit LED display television which is much lighter and thinner and better able to be mounted.

The current market leader is the [http://ledhdtvtelevisions.com/samsung-led-tv-series/]Samsung LED TV with 2.5 million sold in 2009. For more related articles see [http://ledhdtvtelevisions.com/]LED TV Information.
