Understanding LED Television Technology

December 14th, 2009

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.

Initially of course, it may seem just another way for the major players in the world of TV screens to get their hands on more of our hard earned money. But it is more than this; it is a step forward and the benefits to be had are far reaching.

In essence, an LED television is just the same as the LCD that is probably sitting in your lounge right now. The difference is regards how the light emitting diodes, (LED), send the light to the screen. This is of course very complex, but in layman terms relies on backlit or sidelit, (edge), technology.

Having the lights set up in this way allows for greater control of the picture; lights can be dimmed and brightened independently of their neighbours; creating a richer content and feel and most important of all, creating true image black scale; they key to picture quality.

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.

However, new technology does of course command a higher price; and whilst quite sizable LCD screens can now be purchased from six hundred dollars, you will not find many LED screens bigger than fifty inches for much less than two thousand five hundred. The savings on energy consumption, (estimated to be around forty percent), will offset this somewhat of course.

The benefits then are quite significant with this new technology; better pictures, better lighting; better control, and all whilst having a positive impact on the environment. Indeed, the only downside remains the price.

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!)

LED Television: The Next Generation In Flat Screen Technology

October 4th, 2009

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.

To appreciate this however, it is necessary to understand where LED television technology differs from what has gone before. In the most basic of levels, LED technology is simply a progression from LCD; it uses the self same screens for a start; and works in much the same the way. The difference lies in how light is sent to the screen; with LEDs, this is done through backlighting or side lighting.

Having the lights set up in this way allows for greater control of the picture; lights can be dimmed and brightened independently of their neighbours; creating a richer content and feel and most important of all, creating true image black scale; they key to picture quality.

Increased image quality then; but where is the catch? With regards the unit itself; remarkably none. These LEDs are able to produce such content, whilst using less energy. More impressive than this, is that the energy consumed is well used; resulting in less heat and light wastage. Great for the environment then and great for your finances. Also an LED television will last a lot longer, and not really succumb to wear and tear, which makes it well worthy of consideration.

Another benefit to be had from an LED television is the size. Now, we have gotten used to TVs being slim affairs, able to be housed anywhere including on a wall. And though they are only a matter of inches in width, LED screens trump this easily; more likely to be measured in millimetres!

There is of course a catch when looking to buy yourself a shiny new LED television. And that is of course the initial price. Even the smaller sized screens command prices in the five, six and seven hundred dollar region. For this price, you could buy a forty six inch regular LCD TV in some areas. You will not be able to buy an LED television equivalent of this size for much less than two thousand five hundred dollars.

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.

The good news for LED television detractors then is that the prices will inevitably fall; and the benefits will still be there, (and probably improved upon even more). However, it is also likely that new technologies will just about be ready to launch by this point, as the wheels of progress continue to turn.
