The main difference between LED and LCD televisions is the backlighting. The latter is more efficient, but it costs more than the former. An LED TV has a full array of LEDs, whereas an LCD TV has an edge-lit panel. Despite this, many LED TVs still have inferior picture quality.
If you're looking to buy a new television, one of the first choices you'll make is whether to go with an LCD or an LED TV. While both of these technologies are still relatively new compared to today's technology, there are pros and cons to both types that will help you make an informed decision.
