LCD screens actually suspend liquid between two transparent panels. When the liquid is activated by voltage, the individual crystals take on varying colours to produce an image.
LCD screen sizes range from 13 inches to 46 inches with larger models still in the works.
LCDs are not susceptible to ‘burn-in' (when an image remains on the screen in shadow after a certain amount of time) as plasma televisions can be.
Newer LCD screens have a viewing angle of up to 175 degrees.
