Review of New LED TV Screens
TVs have come a long way since their first conception. 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. We have come a long way since then and new generations have brought with them such things as wide screen, flat screen and surround sound.
The latest innovation in the world of TV is LED backlighting. LEDs are cropping up all over the place recently, in everything from car headlights to light-up crystal vases. They are popular because they are very reliable, create very true light and use a great deal less energy than other forms of lighting. 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. What this means then is that many manufacturers are able to produce TVs only 2.5cm. Advanced colour gamut and improved dynamic screen contrast are other steps forwards.
The LED-lit TVs are also more kind to the environment (and your wallet) than the old lighting. The LED lights consume only around a 4th of the electricity that the standard fluorescent lights do. Further more, when it comes to disposing of them, there is a great deal less pollution. 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.
