LED edge lighting is a popular technology because it enables manufacturers to make tellies with the whisper-thin profile of a supermodel after a particularly minimal lettuce salad. That makes them suited to hanging on your wall. It's a good technology for the most part, although it's not as bright as a direct LED backlight system, and, on TVs larger than 50 inches, you're likely to see less light in the centre of the image than at the sides. We were recently told by Toshiba that the British public would rather have slender sets than high-quality pictures. We nearly vomited in disgust.
Although better than CCFL backlights, LED edge lighting can require a fair amount of power, because the process of getting light across the whole of the LCD panel means you need higher brightness levels than in a direct system.
