Modern TVs are unrecognisable when compared to their first ancestors. You used to have to sit a meter away if you wanted to see anything at all and you only got black and white with the first models. With each generation of TV, technology has moved on and we saw the likes of stereo sound, LCD, plasma and even touch-screen to name a few.
The newest television innovation to make its way into the market is LED-lighting. LEDs are cropping up all over the place recently, in everything from car headlights to light-up crystal vases. Their popularity stems largely from their durability, their ability to create very pure light, and their energy efficiency. The florescent lights that are used in most standard TVs worked well for a long time, but technology moves forwards at an alarming rate and the old bulbs just dont cut the mustard any more.
The LED back lighting has come about largely because there is an increased demand for better definition on TVs and the world is also going slim line. People want their phones, stereos and even vases slim line these days, and TVs are no different. Unlike traditional lighting, LEDs only need to be situated on the edges of the screen as a diffusion panel is used to spread the light over the whole screen evenly. This means that many models are only around an inch thick. They also provide greater dynamic contrast and offer a wider colour gamut.
The LED-lit TVs are also more kind to the environment (and your wallet) than the old lighting. This form of lighting uses around four times less energy than fluorescently-lit TV screens. When the TVs are finally disposed of as well, their pollution levels are much lower than fluorescent TVs. Additionally, LED-lit televisions are less prone to power-surge damage and even water damage. That said, its not advised that you start resting your wine glasses on top of them, just in case.
