How LCDs Work

Another difference between LCD and Plasma screens is their principles of operation. How you light up pixels and sub-pixels to produce an image varies, and LCDs require a backlight to provide the necessary excitement to the pixels to make an accurate depiction of an image. Plasma screens use the properties of inert gases to light up pixels.
