LED TV-Don't Be Fooled, Understand the Technology First

A new range of LED TVs that have hit the market with a big buzz. Samsung have crept through the backdoor and have released the 7000 series range with LED technology.

That's great ... but what is this LED technology thats being boasted?

Current LED > TVs-The Truth The term 'LED' stands for Light Emitting Diode and as you may well know LEDs are used in many of our devices at present, however in terms of the current line of LEDTVs, the actual LEDs are used for the backlight of the TV ONLY and not the TV display themselves. If you consider that current TV technology uses CCFL (Cold Cathode Fluorecent Lamps), there is no doubt that an LED backlight is a more efficient form of backlight.

However, the important point here is that the LED television's display is actually LCD (Liquid Crystal Display), it is the backlight only that is made up of LEDs. So there are two major technologies at use here; LCD for the display and LEDS for the backlight. In essence a more advancedform of LCD TV.

When you compare this technology to a true LED TV display. Displays such as OLED (Organic Light Emitting Diode) will self illuminated, utilizing an internal thin layer of LEDS for its display only.

The fact that The 'LED TV ' term has been used to describe a type of LCD TV is a cunning move on Samsungs part, but genius in terms of marketing, since it capitalises on the current buzz in the TV market of true LED display TVs such as Sony's XEL-1 OLED TV.

LCD TVs with LED Backlights – The Improvements Now that we've established that this is an LCD TV with LED backlight, lets look at how this new range of TV improves on current TV technology such as plasma and LCD in 3 standard keyareas:

1. Picture Quality Quite simply, the picture quality has been improved over standard LCD and Plasma, because the range of colours have increased. The utilization of Light Emitting Diodes as a light source instead of traditional lamps provides a higher contrast ratio because the LED produces blacker blacks and whiter whites, this is the key to achieving quality images on screen.

2. Environment LED Technology consumes less power than current backlight TV technology, making a saving on your energy bills.

3. Slimmer Models. Since no provision for a conventional light source is required, LED TVs can be made ultra thin, this makes for a thin, sleek, more attractivemodel.

Decisions, Decisions If you are in the market for a TV now and want to picture quality in advance of current standard LCD and Plasma ranges on the market, then you cannot go far wrong with an LED TV.

However, if you are in no hurray to purchase a TV at this present time and require a TV with technology that will keep it at the forefront of cutting edge, in terms of LED technology, OLED TV is the real deal. Laser TV is another option to explore.

Both are emerging technologies and require patience as they find their place in the market with the correct size screens for your home. These TVs may also require you to dig a little deeper into your bank balance.

A plasma television will significantly minimize any blur and deliver a clear picture; a must-have for all those sports fanatics who can't miss a moment of action. With Plasma, you also have a wider selection of screen sizes and it provides better contrast. The drawbacks of Plasma televisions are all the heat it produces. If choosing this type of television you'll definitely want to place it in an open environment with good ventilation.

The best 60 inch TV doesn't have to be a Plasma television however for this sizeit's not recommended that you purchase an LCD model. It's been found that LCD televisions larger than 30 inches for the images take longer to adjust which can become a pain when changing channels. Additionally, viewers cannot fully enjoy watching an LCD television unless they are sitting dead center in front of it; sitting at an angle causes the picture to become blurred. In any case, the picture quality is definitely higher on smaller sets so while trying to choose the best 60 inch TV, rule this type out.

LED televisions are the latest models with accurate images and crisp color spectra; however, you'll experience the same viewing issues when sitting at an angle.

As noted before, the power usage of Plasmas are unbelievable. To provide an adequate picture it takes alot of energy and gives off a lot of heat. LCD and LED televisions use less power which translates into less energy and less money.

You can expect to pay a few thousand for the best 60 inch TV for your home and keep in mind, no television is perfect.

There are three makes people swear by either because of the quality of pictures or the value and price; Sony, Pioneer and Vizio.

Samsung – The Best LED TV on the Market For Many Reasons

Just when you thought HDTV could not get any better, Samsung has taken it further, much further. By taking a very old technology, the LED (light-emitting diode), and the many advances that have been made in the field, Samsung has been releasing the best LED TV on the market.

Whether it be in the LED LCD HDTV line ' or the new Samsung LED DLP HDTV line, these new televisions are producing images that are simply stunning. With contrasts ratios of 500.000: 1 being offered in current LCD devices, as well as blur-free imaging, these LCD HDTVs aren'twhat you're used to seeing. With much brighter, more vibrant colors as well words really can't do the images justice, they truly must be seen to be believed.

Not only has the Samsung worked their magic in the Samsung LED LCD TV line, but they have also advanced the LED DLP TV sets in leaps and bounds.

DLP is Texas Instrument's amazing chip that houses millions of microscopic mirrors that can switch states at incredible speeds, offering the best images in projection television (and commercial applications as well) that have ever been seen. That, of course, was until Samsung decided to set the bar even higher.

The older versions of the DLP system used in high power arc lamp as the light source for the DLP system. There was also a spinning color wheel used inthose original devices. What Samsung has done with their new line of DLP LED TV technology is to take the best of the old and improve on it greatly.

Instead of using the arc lamp, which is costly to operate (and replace every few years) they use their own LED light source. They've also eliminated the spinning (whining) color wheel, which is one less item to break or wear out. This isn't about changing for the sake of changing though, these changes have resulted in HDTVs that have up to a 40% brighter image, with such brilliant color capability that many high definition sources can't even fully take advantage of the increased color gamut, as of yet anyway.

Of course without the high powered lamp to power on, the Samsung LED DLP TV also has near lyinstantaneous startup. Add to that a much lower operating cost by not powering the arc lamp, and the savings that will be realized when you don't have to replace the lamps, and these devices are attractive in so many ways ... even including the surprisingly low cost.

Although it's still possible to get a comparable image on the highest priced plasma sets, why pay several times more to do it? Especially when the plasma tubes have a relatively short life and are on their way to the old technology heap in a very fast way.

LED HDTV-Understanding the Different Types of LED Televisions

There are two main types of the LED HDTV, and they can be split into two different versions by the type of back lighting they use. One is called an edge-lit LED'S and the other is known as a back-lit LED television. In this article we will look at the back-lit LED HDTV and try to understand how it works.

LED HDTV-Understanding the Different Types of LED Televisions

What is a Back-lit LED HDTV?

All TVs of this type are lit by LED lights, which have been shown to give some advantages over other types of lighting. Back-lit LED televisions have the LED lights placed directly behind the screen, which is similar the the way an LCD TV has it's lighting arranged.

These LED lights are placed into blocks, and are groupedtogether so that they can be controlled at the same time. Therefore, each block has the ability to be switched off and on separately to the other blocks around it. The advantage of this is that in an image with some dark areas and some light areas, the dark parts can have their blocks of switched completely to enable an completely black signal.

This extra control isn't possible on an LCD television.

Local-dimming Technology

The name of this technique is local dimming, and this is the term you should be looking for if you want to buy an LED TV that is built in this way. The main advantage is an LED HDTV with this type of technology may have a better contrast ratio than other types of high-definition television. LCDs have always traditionallyhad a problem with a poor contrast ratio compared to that of a plasma TV, and so this method of backlighting effect is aimed at addressing this problem.

The Problems With Local-dimming

As ever with all of this technology, there is a downside to this idea. The problems occur when one block of lights is covered by a light and a dark part of the image. This will then have the same problems associated with an LCD TV where the block cannot be switched off completely, and so it is impossible to get the black part completely dark.

There is a way to resolve this issue, and that would be to have one LED light for every pixel on the TV screen-but the problem with this is that it would be far to expensive to build a TV in this way and so they would be too expensive formost people to buy. However, with all things taken into account, this method of building a back-lit LED HDTV does generally produce a TV with a better picture than that of most LCD TVs.

LED HDTV Summary

So as we can see, there is actually more than one type of LED HDTV that you can buy, and the way that it is built can have a big effect on the quality of the picture that you get. So if you are looking to buy an LED TV then it is important to understand the differences in design because they can have a big impact on the performance of the TV.
