With technology rapidly evolving, the entertainment industry is experiencing new and more innovative techniques everyday. The latest technology available for the television world is LED. The days of bulky cathode ray TVs taking up an obscene amount of living room space are long behind us. The new age of sleek and slender looking LED TVs is quickly rendering any older models as obsolete, not just cathode ray TVs but also its successor, the LCD TV. LED TVs use a collection of LEDs as their backlight source rather than CCFLs. In this technology the panel is dotted with thousands of LEDs that are turned off or dimmed in groups.
LED TVs create an amazingly sharp picture with accurate colours. They have the capability of simply dimming or turning off selective areas or groups, therefore they are able to create blacks more efficiently. This process helps to reduce light bleed from behind the panel and so creates deeper blacks with an improved picture contrast. This technique works far more effectively than merely closing up the liquid crystal matrix of an LCD TV. Moreover, LED TVs emit a broader spectrum of white light, especially in comparison to that emitted by CCFLs, and it can easily be split up into more colours. Because LED TVs have this broad range of white light they are able to create a more affluent colour experience.
When considering an LED TV there are two different types that you should be aware of; a backlit LED TV and an edge-lit LED TV. Each model displays different lighting patterns. Instead of having the LEDs behind the panel, like a backlit TV, an edge-lit model has LEDs bordering around the outer surface of the liquid crystal matrix. A specially designed panel that creates a uniform light source behind the panel diffuses the light that emerges from the LEDs. The main advantage of using this edge-lit technology is that the space saved on the panel of LEDs allows for an even flatter and thinner TV. However, the cons seem to out weigh the pros when it comes to edge-lit TVs. Yes, they can be thinner but the selective dimming available on the backlit model allows for deeper blacks and better contrast, and the white light produced by an edge-lit TV produces a narrower spectrum than backlit TVs.
Another plus side of opting for an LED TV is that they are far more energy efficient than older models. With the world striving for a greener approach to life this has to count for something. Not only is this better for the environment but it also means you will save money on your electricity bills. LED TVs are so energy efficient that they are able to save 40 per cent more electricity than a standard LCD TV.
