Know your TV

An LCD TV has liquid crystal between the Display Panel of the TV, which gets activated when an electric current is supplied to it.

The LED TV works on the same liquid crystal platform, but light-emitting diodes (LED) are used as the back-light for this TV, while the normal LCD TV uses a CCFL back-light.

Sitting at the right distance from your LCD TV is an important part of optimizing the viewing experience. Sitting too far away from a small- or medium-sized screen definitely diminishes the overall impact. At the same time, sitting too close to a large screen is also less than ideal.
