Display
Plasma tvs are thin and lightweight and capable of being mounted on a wall like a painting. Their main advantage toward LCD is that they are capable of showing a more intense black.
LCD stands for Liquid Crystal Displays. It is a flat panel technology which uses liquid crystals sandwiched between two glass plates. These TVs can be even thinner than plasma screens and they normally use less energy. LCD-technology is the most common technique today.
LED-tvs are newer versions of LCD-tvs that use light-emitting diodes as backlight. This allows them to show black and dark colors more intensively.
