Full Answer

LCD screens consist of a polymer holding liquid crystals in place on the screen, which joins a layer that allows an electric charge to be delivered to individual liquid crystals. That charge causes the crystal to either pass or block the light from inside the screen to produce the image. Plasma screens consist of an ionized neon-xenon gas mix suspended in a plasma state inside the screen during manufacture. An electrical charge causes the gas to glow red, green or blue for each pixel to produce the image.

Plasma screens offer better color and contrast compared to LCD screens, along with superior rendering of motion. Plasma screens operate at a higher temperature and consume more energy than LCD screens of similar size, but they can have problems at high altitudes due to the pressure of the gas used in their manufacture. LCD screens generally have less glare than plasma screens. They operate at a cooler temperature and produce a brighter image.
