LEDs or light emitting diode technology has been around for a while, whereas the use of LEDs  for illuminating the screens of LCD TVs is relatively new. Cold cathode fluorescent lamps are used to illuminate traditional LCD TVs; the LEDs replace these lamps with hundreds of the smaller LEDs. This new lighting system is very popular with consumers and some predict LED lighting will replace all other technologies in the near future.

Are all LED TVs the same?

There are two types of LED illumination one called edge lit which uses LEDs just around the perimeter of the screen and full array lighting which uses the LED’s across the entire back of the screen. Sharp and Toshiba use the full array lit technology while Sony, Samsung, Vizio and LG use the edge lit technology. Philips offers an edge lit model and a full array lit model with LED’s backlighting the entire screen.

The edge lit LED TVs are thinner and less expensive than the full array LED lit TV’s that use LEDs across the entire screen. Some complain the Sony edge lit LED TV’s have an uneven lighting effect especially in the corners of the screen. The newer Samsung edge lit models seem to have solved the uneven lighting effect with a light diffusion technology.

Which LED lit TV is right for you?

Which LED TV is right for you is really a matter of personal preference and budget. All the LED lit TVs offer a sharper picture, use less electricity, are thinner, and require less warm up time than the conventional LCD and plasma TVs.  However, there are some disadvantages too.

Who makes LED TVs

Currently Sony, Samsung, Sharp, Toshiba, Philips, Vizio and LG have LED TVs on the market. The least expensive LED lit TVs are the Sharp and Vizio models. The best rated by consumers are Sony and Samsung.
