The Latest Development In TV Technology - LEDs
Modern TVs are unrecognisable when compared to their first ancestors. With the old models you only got a picture if you sat square on to screen and squinted to make out people and objects. 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. 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 don’t cut the mustard any more.
An increase in demand for faster, slicker and more defined pictures, coupled with a desire for everything to be super slim, goes some way to explain why LED lighting found its way into TVs. 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.
Another benefit of the LED technology is that it is a lot more environmentally friendly. The modern lighting method uses around 75% less energy than the conventional fluorescent lighting. 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, it’s not advised that you start resting your wine glasses on top of them, just in case.
