Understanding LED Television Technology

By Wayne Torres

It was not too long ago that we were arguing the case for and against LCD and plasma televisions. And though LCD TV eventually came out the victor, due to its superior all round function and practicality, its crown is now under threat. That this threat comes from its sibling the LED television, is all the more intriguing.

Cynics out there, (of which I am a fully paid up member of the club), will snort at such an announcement and claim it is nothing more than a money making exercise. And whilst this holds some water; the technology in an LED television is a step in the right direction, so should not be dismissed too readily.

Essentially, LED television, (light emitting diode), technology is no different to that already seen with their LCD televisions. It is simply another way of lighting the screen itself. Simply put, an LED television creates an image using back lighting, (or side lighting), from the diodes within the unit, as opposed to relying on liquid crystal displays to produce the same effect.

Sending light to the screen in this way allows for far greater control over the picture quality, definition and brightness. Each diode can be controlled independently, allowing for smoother flow through the image projected onto the screen. Deeper colors and blacks are the result, delivering a far truer picture that feels as if you are looking at something through the human eye.

Whilst the benefits are far reaching with LED television technology being able to produce better quality images with high brightness and contrast levels, the benefits do not stop here. This better quality image is produced using less power and creating less light and heat wastage. This of course also allows the lifespan to be much longer than even the most robust of LCD TV currently on the market.

The depth of the TVs is also thinner than what is presently available. Amazing as this may sound, it is quite true. The depth of LCD and plasmas are presently given in inches, an LED television will be measured in millimetres; with somewhere around 9 or 10 being the standard, though screens of just 6mm are available now.

Okay, this all sounds excellent but of course, it isn't all good news. Whilst no limitations exist to the operation of an LED television, there is a limitation regards affordability. It is really no different to the large prices that LCD and most particularly plasmas were tagged with though.

In summary then LED TVs are just a natural progression from LCDs. It gives us better pictures, less operating costs and space saving abilities. The prices are really the only issue presently.

But these prices will fall as demand picks up and we really recognize the benefits of LED television technology, (and as newer technologies come on line of course!) - 29872

Watch HDTV On A PC

By Dorothy Grant

Watching HD TV on your PC is so simple even the most PC illiterate of us should be able to do it. There are two easy methods to achieve this objective. The 1st way is to invest in a piece of hardware which turns your PC in to a TV. The second way is to simply use one of the many internet HDTV broadcasters.

The fist way of turning your PC in to a TV requires the purchase of a PC TV tuner. This is a piece of hardware that takes a TV signal and displays it on your TV. They come in the form of a PCI card or a USB adaptor. Both do the same job and are easy to install. If you have a desktop PC then either type of adaptor should be suitable. However if you have a notebook or laptop then USB is the way to go.

There?s a lot of choice when it comes to buying a TV tuner adaptor. Though they all have the same basic purpose, they also have optional features and capabilities. Be certain that the type you buy is capable for use with the TV signal you want to watch.

Some TV tuner adaptors have inbuilt aerials and/or a connector for an external aerial that comes supplied. For the best result you might want to check if the adaptor has the right type of connectors to connect to your satellite or set-top box if that?s your chosen method of viewing. They normally come with software to tune the adaptor into the TV channels and allow you to perform other functions like recording and pausing TV channels.

TV tuner cards are not expensive, there is a big choice to consider though. Your best option might be to look at a comparison websites to compare prices features and read others people?s reviews.

The second method to view high definition broadcasts on your computer is by using the internet to watch HDTV online. There are many websites online that stream TV channels over the internet for viewing on your PC.

The benefits of this are that if you already have a suitable computer and internet connection then there is no extra investment in hardware required. You don?t need a super computer or a mega fast internet connection (2mb connection and above should be fine).

There are numerous providers of TV broadcasts on the internet. Just open your browser and search for ?watch TV online? to see for yourself. You will find some which are free, the quality of the broadcasts is usually poor and the range of channels is limited, they will largely be channels from around the world that you have never heard of. There are TV channel websites that involve fees these have are usually better quality with more familiar channels.

The advantages of watching HDTV online is that firstly you don?t need to buy an expensive HDTV and receiver and it is cheaper than subscribing to a satellite or cable TV company. The other thing is that it is mobile, wherever you have an internet connection you can watch HDTV online. - 29872

A Singer for all Generations

By Patrick Daniels

A popular favorite among lovers of the big band, swing and contemporary music genres, is Michael Buble. Although his album of full of cover songs, mostly, he adds a special touch to these old favorites and makes them his own.

Many say is voice is reminiscent from the Frank Sinatra era. He has an old sounds and a voice that makes you believe no matter what he sings it will be outstandingly enjoyable. His music is loved by many, whether it the skates that he adds to songs, or just his voice alone, people will stop just to hear him.

While listening to him sing, many find it hard to believe that Michale Buble is a Canadian. The American songs he sings are breathtaking, without any trace of an accent. Michael has been know to take standard favorites and make them into contemporary hits. He has even done duets with contemporary artists, including Nelly Furtado. You will always be able to find one or two contemporary tracks on his CD's, however all the tracks include that big band instrument sounds that he has become famous for.

The most known, and loved, album from Michael Buble is "Home". This album is one of a kind and complete with a few Michael Buble originals. Since the release of this album, fans have been anxiously awaiting another one. He has, however, done a small album release with Hallmark, some singles, and movie soundtracks. One single that was released was titled "Totally Buble", this was the soundtrack for the movie Totally Blonde, and there was another single that he cut, which was featured on the Spiderman movie soundtrack. Fans will be excited to hear, that I have just learned there is a new CD scheduled to be released later this year.

A Christmas album would be a great surprise for Buble fans. A new CD would spur some hope in fans for a concert tour as well, this would give fans an opportunity to see how Michael Buble is as a person, and he is actually pretty humorous in nature.

Michael's music appeals to everyone, across generations, genders and from young to old. You will find children singing alone to his songs, with their grandparents and their parents all the same. No matter what type of music you enjoy, almost everyone has stopped to listen to a Michael Buble song. He is a talented singer, right up there is the ranks with Frank Sinatra, Ella Fitzgerald, and others from the era. If you have never listened to a Michale Buble track, I encourage you to do so. I guarantee, that even if you are a rock fan, you will be swept away by his music, his voice and his sounds. - 29872

What Are The Advantages Of OLED Televisions?

By Jimmy Tyrrell

Over the last eighteen to twenty four months, anyone looking at buying a new television would have most likely come across chat about OLED televisions. The latest advancement in TV technology, it has been spoken about with the industry for quite some time before this. However, finding out exactly how and why it is said to be such an exciting progression can be tricky.

Firstly it is important to discuss just what OLED means. Standing for Organic Light Emitting Diode, these diodes give off their light in a different way than what has gone before. Its predecessors came in the form of LCD (liquid crystal display) and LED (Light Emitting Diode) television screens. The screen is made up of several conducting layers which emit light through an organic process; thus a backlighting function is not required.

This is of course a significant advantage for OLED televisions. The quest has always been to find the perfect black color, (which essentially controls viewing clarity), with this; a true black color is delivered to the viewer.

The advantages to be gained continue with the slimness that can be achieved with the screens; the slimmest of which is currently just 3mm. With no need to create a casing for the lights anymore, screens can also be moulded to suit practically any shape and curve.

This also allows the screen to be extremely resistant to damage and scratching; ideal for televisions and many other applications such as advertising boards, cell phones and a new concept in interactive printed media. The screens are also extremely thin, the thinnest out there reputed to be just three millimetres in depth.

However what the screen "lacks" in depth, it also certainly LACKS in size. Presently, the biggest screen made, (and shown to the public), is a rather small fifteen inches. However, despite this, resolution and contrast are amazing.

Then of course there is the issue with pricing. The biggest screen widely available is a mere eleven inches across the diagonal, and is priced at an eye watering two thousand five hundred dollars. Considering a nineteen inch LCD screen can be bought for little over a hundred and fifty bucks, highlights the challenge still faced in this area.

Another downside to an OLED televisions is the short life span which, will also be a concern; particularly when countered against the price, (though the unit themselves use much less power than LCDs and LEDs and so this counter balances this to some extent). Also at the moment availability is not widespread either.

It is still a relatively young technology though; with a lot of advancements yet to be made. The price will of course fall as demand picks up, the technology really becomes commercially viable and life span is improved.

OLED televisions are a fantastic new concept, and such is the uptake by the big players in the electronics manufacturing, it is only a matter of time before the war starts between LED and OLED in earnest. I for one cannot wait; bring it on! - 29872

LED HD Television

By Paul Harrison

LED TVs and displays employ a new technology which a have improved the viewing experience. They have now been made thinner, lighter and have a better picture quality than their conventional LCD counterparts. The advances in this area resulted in Samsung selling approx one million LED TVs worldwide in the first six months.

LED displays are not radically different to conventional LCD displays. They still use LCDs, the difference is with the source of lighting used in these displays. Rather than using fluorescent lights as previous LCD displays have, LED TVs and displays use LEDs as the screens lighting source.

The use of the phrase LED TV has come under some scrutiny. In the GB the ASA was critical of the use of the phrase and said it was misleading to consumers. It indicates that LEDs are more significant than they actually are. In the end manufacturers agreed that they would make the function of LEDs in these televisions clearer in their advertising. Other makers of TVs indicated a better description would be to call such displays LED lit LCDs.

You will currently find LED televisions and displays being produced by JVC, Samsung, Sony and Philips. They will all claim that LEDs are advancement on previous LCDs. To summarize they allow today?s displays to be manufactured lighter, slimmer, eco-friendlier and of course improved images. Because they are new to the market they are however still quite expensive when compared with standard LCD displays.

The LEDs are used in either side-lit or back-lit arrangements in LED TVs. Edge-lit LED TVs as the name would suggest use LEDs round the side of the LCD display. The TVs can be made much slimmer because LEDs take up less space than the fluorescent lights they replace. Back-lit LED TVs are not quite as thin but have the added benefit that the LEDs can be locally dimmed to produce better contrast with darker blacks. LED TVs can be made as little as 10mm thin.

The colours are claimed to be further enhanced with LED lighting. This can be explained by the fact that LEDs produce a full spectrum of light when compared to fluorescent lights. The contrast control is also improved.

LED monitors as well as TVs have extended life expectancy with the introduction of LEDs technology. LEDs have a longer lifespan than fluorescent lights and, as LCD TVs are not designed to have the fluorescent lighting replaced when the backlight begins to dim or fails then there is little that can be done.

In a world that is becoming ever greener, LED TVs are doing their little bit. They are more eco-friendly than older LCD TVs. This is because of the improved efficiency of LEDs. Manufacturers will claim that LED TVs use up to forty percent less energy than standard LCD displays and even more when it come to plasmas. Another point worth mentioning is that fluorescent lighting contained mercury which has obviously been eliminated. - 29872

HDTV Online Is Changing The Way That You View Television

By Eric Hendrix

HDTV online has only been available for a short period of time and people are already head over heels for it. The internet continues to grow day in and day out, there are millions people that use the internet for various reasons. Therefore many people believe that it was only a period of time until television became part of the internet as well.

High definition television, avidly referred to as HDTV allows the viewers to set their sights on a picture that has been taken at the highest resolution possible. People are able to see different things that they would normally not catch if they were viewing their favorite shows off of a normal television set.

With the expense of cable and satellite services soaring through the roof, many people are finding it difficult to afford both their internet service as well as their cable service for their television. The other fact of the matter is more and more people are spending more time on the internet in comparison to watching their television.

It was only a matter of time until television and the internet collided. Many people are utilizing HDTV online in a means to cut down their monthly expenses that they would inadvertently end up paying for cable or another source of television entertainment.

People still want to be able to enjoy the shows that they avidly watch on television, yet they don't want to compromise utilizing their computer over watching television. Therefore, it was just a matter of time until the two were incorporated together to make like a lot simpler.

There are some sites on the internet that offer a free trial for their HDTV online, while others will make you sign a contract just like you do with your normal cable providers. You are still allowed to get the same great channels that you avidly enjoy watching on TV. The only difference is instead of having to set in front of a television screen to enjoy your programs you can enjoy them right in front of your computer.

However, you do need to be aware that there are some scam sites that claim that they are offering HDTV online and simply do not follow through with their promise.

Sad to say, that even the newest addition to the internet which is the HDTV online has scammers that are trying to steal peoples information. Before you ever insert your credit card numbers into a database in order to obtain the television you need to ensure that the site is legitimate.

LED High Definition Televisions

By Ricky Strauss

Watching television is a favourite pass time to people all over the globe. In fact, using the TV to play games and watch movies has become such an important part of the lives of society, that manufactures continue to search for ways to enhance the television experience. In most cases, this includes a clearer picture, a bigger screen, or better sound. All of these aspects are wrapped up into the latest TVs inventions known as the LED high definition television.

This drive toward giving viewers a more enjoyable TV watching experience has lead to the latest in trends, the LED television. In basic terms, a LED TV can exist as a LCD TV that uses Light Emitting Diode (LEDs) to clarify the picture screen display or as an LED TV which uses complete LEDs. LEDs more effectively direct light in one direction than fluorescent or incandescent bulbs. In a LCD TV, the LEDS are either placed along the back of the screen or around the edge of the screen. When the LEDs are used along the perimeter of the display screen, the term edge lit is labelled to the product.

The use of LED technology in the edge-lit or back-lit options work somewhat differently. Lining the edges of the screen with LEDs allows for a sleeker screen because no LEDs are used in the back. However with LEDs located across the back of the screen, darker blacks are formed because LEDs can shut off not allowing light to peek through resulting in a term called local dimming. In most cases, the back-lit LED television cost more than the edge-lit LED television. Both methods allow for great viewing color and picture perfection.

The cost of the clarity and color improvements with a LED HDTV comes with a cost. An upgrade to one of these televisions may cost the buyer up to $4000. Yet, with the upgrade the viewer gains much intensity in action films and gaming. LED TVs are more efficient at creating excellent pictures of fast motions. The LED HDTV manufacturers also claim that television cuts energy consumption by 40%.

Once the decision to upgrade has been made, there are several factors to consider before shopping for a new TV. A careful comparison should be made between LED TVs, LCD TVs, and Plasma TVs. The newest of the three, LED TVs, offer larger screen options. Their viewing angle is still short of the plasma but the reflective screen and burn out issue are not a problem.

LEDs group together to form small dots or pixels in a LED screen. While all LED screens offer high resolution, the amount of resolution depends greatly on the pixels. Red, blue, and green pixels work together to form other colors as well as white. The distance between the pixels on a LED screen is known as pixel pitch. The smaller the pixel pitch of the screen, the closer the pixels resulting in a higher resolution. High quality LED screens may contain over 9000 pixels per meter. These LED screens are limited to 40 inches or larger.

In addition to LEDs making their way into the world of television, they are now breaking ground with the LED monitor. The once popular flat screen LCD monitor has been outdone when it comes to color accuracy and precision. The LED monitors are created without metal that is found in other bulb type monitors. NEC is one of the first to put the LED monitor on the market with a cost reaching up to $6000 or more to purchase.

All reviews and indicators point to LED technology as being the electronic of the future. While high cost and screen size limitations are a factor in the LED world now, manufacturers show promise of working through these issues. In given time, LED electronics could possibly be a normal in the homes of all television watchers. - 29872
