LED TV – Don’t Be Fooled, Understand the Technology First

Thinking of buying an LED TV, well….Stop! Before you spend in excess of $1500, you need to cut through the jargon and hype to truly understand the technology that you’re actually spending your hard earned money on. TV manufacturers and the media are very good at convincing us that the latest products incorporate the most cutting edge technology and are a must have. Lets get real here, to the average consumer most of this jargon is just down right confusing.

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 boasting 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 LED TVs, 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 LED for the backlight. In essence a more advanced form of LCD TV.

When you compare this technology to a true LED display TV. Displays such as OLED (Organic Light Emitting Diode) will self illuminate, utilizing an internal thin layer of LED 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 LCD TV with an LED backlight, lets look at how this new range of TV improves on current TV technology such as plasma and standard LCD in 3 key areas:

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 attractive model.

Decisions, Decisions If you are in the market for a TV now and want a 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 television 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.

The moral of the story is to understand the technology behind the product in great detail before you part with your money, the choice is yours.

Recently we celebrated the ‘earth hour’ where households and buildings participated by turning off their electricity for an hour. The power savings made by every TV turned off, multiplied by the number of the houses that participated was staggering. But can you imagine the power savings we can have if all households use a LED TV?

It’s a huge number. And huge numbers can have a big effect on anything. And for Mother Earth, it’s a big break from all the carbon and heat emissions of fossil fuel powered companies and households.

It is said that the LED TVs designs can save up to 40% energy compared to that of normal TVs. LEDs are not new, they have been around for several decades now. Your father might tell you about times past when calculator displays had green numbers. Car light manufacturers noticed the energy savings from using LEDs and developed designs for head and side lights that utilized them. There are also new flashlights made of multiple LEDs clustered together.

Of course, you’ll see LED lights on many appliances, the small green, blue and orange dots of light on the power button, and even on your mobile charger. They are everywhere nowadays, and now LCD screen manufacturers have incorporated the technology in televisions. LED TV technology is still new and has not yet reached its full potential. This is the reason why LED TVs are still expensive compared to standard LCDs. Companies are constantly thinking of ways to incorporate LEDs in any type of display, and to develop designs that are more energy efficient than ever before. And like all new technologies, the price will become even more affordable eventually.

So for the future home, we are sure to find new breeds of LED technology, like replacing our old CFL bulbs with LED lights. Further than that replace our old TV with an LED TV. Imagine the power savings a whole country can make when all are using energy efficient LED technologies. It’s a whole new way to light up the world.

3D TV Technology is Here and a New Evolution in Entertainment Has Begun

Remember when the old 3D movies from yesteryear? Cheap and cheesy effects but still a bit fun too as you get to wear those cool (dorky) red and blue 3D glasses to make the action come off screen and right into your face. Even though these were cool for it’s time, today is a different story.

With the huge success of James Cameron’s ‘Avatar’ in 3D the world has been a buzz waiting for this new 3D TV technology to enter our living rooms, don’t blink because it has arrived.

So what is the big deal, it is the same thing as the old 3D stuff right? Oh know it is not. Major changes include high definition 3D for one without the low grade looking graphics of years past, now it looks more real than life itself. The 3D glasses are different too, no more red and blue as they just look like a normal pair of sunglasses with all the 3D technology built into each lens with specific glasses made for 3D gaming, TV, etc.

Only a select few of 3D TV’s and home projectors have hit the market at this time or writing with the summer of 2010 to be the major launch of everything 3D. You will see upgraded video games, TV shows, movies made to match up with the new 3D TV’s and Blu-ray players being produced by all the major electronic companies. Can you imagine the intense fun of playing a shoot em up video game in 3D?! As you may have noticed there are plenty of movies in theaters right now that are viewable in a three dimensional platform thus awaiting their anticipated release on a 3D blu-ray disc for the purpose of enjoying it on your home entertainment system.

These new high definition televisions will be the thinnest ever coming in LED, LCD, DLP, and Plasma varieties all with 1080p respectively. This is just the tip of the iceberg as this new 3D TV technology will also include a more user friendly platform which Samsung has introduced as applications similar to Apple’s apps for their iPhone. You will be able to go online via the Internet using your new 3D TV and use these “apps” to make your viewing experience of games, TV, and movies just that more better and exiting all from your multi-use remote and from sitting on your couch. Syncing your computer directly to your TV will make this all possible.

Just when you thought it couldn’t get any better, it does!

Is LED TV Technology Better For Your High Definition Viewing Pleasure?

Filed under: Led Tv Articles — Tags: , , , , — admin @ 6:58 am

Of course these sleek new LED TVs look outstanding and perform way better than their predecessors but are we to believe they really are “better?” We also have to consider the marketplace as it is standard business practices nowadays to roll out technology in planned increments to increase sales, you don’t want to be stuck with something obsolete do you?

Truth is there are plans for even newer and better technological advances for the future. There is already been huge speculation of a 3D HD TV to come out when ‘Avatar’ is released on Blu-ray, now that is the plan so far. If your still gazing into an old tube style TV and are procrastinating patiently waiting for the newest high definition TV to come out that you can keep for years to come than the wait is really over.

The new LED TV is what should have been when these slim widescreen TVs came out in the first place, but that is where that planned roll out came into play. Already there is technology beyond 1080p, however there is nothing that can match it, yet. Cable and satellite feeds only produce 720p and 1080i respectively so the only true HD comes from Blu-ray. These LED TVs gives you the deep darkness of a plasma TV and the brightness of the LCD TV so it truly is the best out there today. That being said they draw 40% less energy and emit no heat, can’t say that about a plasma TV. The older LCD TV just couldn’t produce those dark colors and looked washed out if you tried to crank up the brightness too much.

The LED light has been around for many years, you recently had a string of them in all different colors on your Christmas tree recently, those lights that don’t give off heat are used in the same manner. For the LED TV each pixel has it’s own LED light while some companies use the out edge to shoot the LED light’s brightness across the entire screen with those particular units being the thinnest out of the bunch.

Let’s take a look at what an LED TV can do and why it is considered the best.

They are more cost efficient in terms of energy usage and emit less heat thanks to OLED (organic light emitting diode) LED technology. Lighter in weight and thinner in appearance so you will worry less about it falling off the wall if you live in an earthquake zone. A jaw dropping contrast ration of 2 million to one (2,000,000 to 1) which lets you see everything in high definition which looks better than real life so it will leave you in awe.

The only drawbacks are that you do see everything, and I mean everything as to a point of utter distraction. I was watching a recent movie on Blu-ray and could see the actors makeup so vividly it took my focus away from the film. The actors face was caked on with an orange-like makeup while his arms and neck area that did not have stage makeup on were ghostly white. Also it took this dramatic film and made it look like a soap opera, now let me expand on that. A soap opera you see on TV is shot on tape, not film so that is why it looks like your home movies on a high grade camcorder as the motion appears to be faster and the lighting is more true, film softens and enhances for a more dramatic effect. That is the drawback of such high definition, it loses the soft film quality we have come accustomed to as a society. The 11 o’clock newscasters look frightening as well even in 1080i through my cable feed because the makeup department has not caught up yet to the technology yet I suppose, the local nightly news is shot on tape as well.

So if your on the fence about buying one of the newest LED TV rest assured you are in fact going to get the highest definition in every sense if that is what your after, to each their own. The only technology that can top this is 3D, but now that will take a while to mature as the entertainment industry still needs to catch up to it.

New Satellite TV Technology To Watch Satellite TV On Your PC

Filed under: Led Tv Articles — Tags: , — admin @ 6:56 am

The advanced technology of our time has enabled us to enjoy satellite television on our personal computers, with no need for a dish whatsoever. Read on to find out how you can watch satellite TV on your PC – with no dish at all!

People in laid-back societies commonly need a dish to view satellite TV. This thing can be likened to an antenna, because it picks up and transfers signals back and forth the nearest satellites. But alas! Setting up such dish is not a piece of meat; it is in fact a tedious challenge for many of us not familiar with gadgets.

You simply set up the satellite dish outdoor and arrange a low-noise block converter (LNB) on it. To cap it off, you would need a decoder or receiver. If the instructions seem so complex, fret not. Now, you can easily set up and enjoy satellite TV right from your PC!

Here are the major computer and hardware requirements before you can start viewing satellite TV on your PC:

1 PCTV Card

In this set-up, your computer will serve as the satellite TV, and your monitor will act as the screen. But you must first of all set your PC to pick up and read the satellite TV channel feed through the PCTV Card. The PCTV Card can be installed internally in the Peripheral Component Interconnect (PCI) slot, which connects such external tools to your computer’s motherboard. The USB ports connect external PCTV cards to your PC. In whatever case, you should be connected to the Internet. If it’s an external card that you’re using, you should first check the availability of your USB ports. If not, you should buy an adapter.

2. Internet Connection

Internet connection (broadband if possible) faster than 512 KB is better. The reason is because high connection speeds produce a higher quality of satellite TV, speedier and easier transfer.

3. Computer Configuration

Not everyone with a PC can set up a satellite TV. Your PC must fulfill the following:

1) Minimum RAM speed of 128 MB.

2) Your CPU should be a Pentium 3, at the least. But these days, almost all computers satisfy these requirements so it will be easier for you.

4. Recommended External Devices

I recommend several external devices which can make you enjoy your satellite TV on PC experience more. Putting in a first-rate graphics card and sound card will surely help. And if you bed in a compatible sub-woofer or perhaps a complete theater system, you’re sure to have a great viewing experience! Surely, this is a good means of viewing satellite television on your PC but relative to the technological rate of our time, there are even better ways. We now can watch satellite TV on our PC through software. If you are intrigued in this copyrighted software, simply visit my blog.

Direct TV Explains Aspect Ratios Of Different Technology

Filed under: Led Tv Articles — Tags: , , , , , — admin @ 6:26 am


Image : http://www.flickr.com

One of the most noticed, but least understood aspects of TV technology is aspect ratio. Aspect ratio defines the shape of a picture that appears on a TV, movie, or HDTV screen as well as the shape of the screen itself.

The aspect ratio is the ratio between the screen’s width and its height. For example, no matter how big the actual screen size of a standard definition TV set, it will be four inches wide for every three inches of hight it has and therefore have an aspect ratio of 4:3. For example, if you had a screen that was four inches on its top edge, the side would be three inches long. By the same token, a screen that’s forty inches across its top, would have to be thirty inches high.

The other major aspect ratio is 16:9. This aspect ratio is what most of us think of when we hear the term “wide screen,” and is the aspect ratio that’s found on big movie screens (the normal type, not IMAX) and HDTV sets. The fact sixteen is the square of four and nine is the square of three should not lead one to believe that 16:9 is another way of saying 4:3. The difference can be observed by taking a close look at any HDTV set or any movie that’s displayed in wide screen format: the width is almost twice that of the height. In the case of 16:9, a movie theater screen that’s sixteen feet across its top edge would be nine feet high. Considering that eight is half of sixteen and that eight is only one less than nine, this aspect ratio does have a much different shape than a 4:3.

Another more obscure aspect ratio is even wider than 16:9. This is used on some films- most notably Star Wars. All you have to do in order to see the difference between this aspect ratio and 16:9 is to walk by an HDTV in an electronics store that’s displaying one of the Star Wars movies. You’ll notice that there is blank screen both above and below the actual image. Occasionally, the blank space at the bottom of the screen- the part that would make up the difference between normal 16:9 and this special aspect ratio- is used to display subtitles when someone is speaking an alien language, but considering how seldom the space is used for that, there must be a different rationale for making that aspect ratio the way it is. Perhaps the extra width was chosen in order to accentuate the grandeur of the story.

Unfortunately aspect ratio is a source of confusion for many people. While it is true that HDTV is never displayed in 4:3 aspect ratio, not everything that’s displayed in 16:9 is considered HDTV. In fact, many TV shows are being produced in standard definition and with an aspect ratio of 16:9. This has led a lot of people to assume that a lot of TV programming is in HDTV format, when in fact it’s not. This is especially true when an an HDTV channel shows standard def programming shot in 16:9.

While aspect ratios may be confusing, they are certainly an aspect of TV technology that can add enjoyment to TV viewing.

Computer Technology Merging With TV Technology More All The Time

Filed under: Led Tv Articles — Tags: , , — admin @ 5:59 pm


Image : http://www.flickr.com

Over the past decade, there has been a phenomenal amount of crossover between computer technology and TV technology. This is especially surprising given the fact that most Americans have largely rejected the idea of a living room computer. However, most of the computer technology that has found its way into the living room hasn’t had the overt appearance of a personal computer.

The earliest example of an acceptable piece of computer equipment in the home entertainment center (that wasn’t a video game platform) was the digital TV receiver. The widespread use of these devices actually dates back to the early nineteen nineties when satellite TV became economically viable for typical households. By all outward appearances, it would have been easy to blur digital TV receivers together with any other set top box, but underneath it all was the fact that they converted digital data to the sounds and images that made up TV.

The DVD player was a much more obvious example of the blurring between computer and TV technologies. After all, by the time that DVD players became common, CD-ROM drives had been on computers for years. Since both are optical drives, and computers and DVD players loaded their discs in similar ways, the resemblance was pretty plain. Of course, CD’s had been in stereo systems and computers for years, so people were already used to seeing the resemblance there.

The next major change was the digital video recorder. DVR’s as these devices are more commonly known, can record video onto computer hard disks and then play that video back later. Most models also automatically record whatever the viewer is watching live in order to enable the pausing and rewinding of live TV. Among the advantages that DVR’s have over VCR’s is an ease of programming that none of the manufacturers of VCR’s ever got right. Another advantage of DVR technology is an ability to watch recorded programs in any order. That’s because a hard disk doesn’t store video sequentially like a video tape does. In other words, a video file can simply be accessed without the time wasted cuing through other videos.

Over the years, computers have also taken on a number of the same capabilities that’s previously only been reserved for TV sets. For example, it’s been possible to buy a special TV tuner that can be installed in a computer for years. These devices allow computers users to watch TV right on their computer screens. These days though, this capability is standard on many computers to some extent. For example, most modern computers can display streaming Internet video on their screens and laptop computers have been used to watch DVD’s for years. There are also now special adapters available that contain a TV tuner and connect to laptop computers through a USB port so that users of laptop computers can watch TV on the screens of their laptops.

The most obvious hybrid between computers and TV equipment is the media center computer. These devices are DVD players, DVR’s, digital receivers, and Internet browsing machines all combined into a single unit. They’re likely to be the future of TV technology.
