<human>:  What is the difference between an LED and LCD TV?
<bot>: The main difference between an LED and LCD TV is the type of backlighting used.LED TVs use a backlighting system which means that each individual pixel is lit up, while LCD TVs use a backlight system that lights up a larger area of the TV. As a result, LED TVs generally offer better color, contrast, and sharpness compared to LCD TVs. Additionally, LED TVs are typically thinner and use less energy than LCD TVs.
