Each television delivers its picture using a specific technology: gas (plasma) or crystals (LCD).
Plasma (gas): Plasma screens are made up of over a million pixel cells filled with gasses. When an electric signal contacts the gas it excites a phosphor, the phosphor emits light of a specific color to create the image on the screen. The gas technology is what allows the plasma screen to be so thin.
LCD (crystal): LCD screens consist of over a million crystals sandwiched between thin panes of glass, with a wafer-thin light source behind the panes. When struck with an electrical current, the crystals “twist” to let through a specific color of light, creating the image seen on the screen. There is no liquid in the LCD. The “liquid” in “liquid crystal display” refers to the crystals’ twisting ability.
