How it Works: Liquid Crystal Display, or LCD TVs use a florescent backlight (see LED Backlight Technologies for an update) to send light through its liquid crystal molecules and a polarizing substrate. LCD TVs work passively, with red, green and blue pixels. By applying voltage to the pixels using a matrix of wires, the pixels can be darkened to prevent the backlight from showing through.
