What Does the Acronym “LCD” Stand For?
Answer: Liquid Crystal Display
Liquid Crystal Displays are used for everything from calculator displays to monitors to portable video game units. The displays are created by sandwiching a layer of liquid crystal (specifically what kind of liquid crystal used varies depending on the application) between layers of electrically conductive polymer and polarized glass.
The layer of electrically conductive polymer can be simple (like the display of a basic calculator) or quite complex (like the panel used for a computer monitor or television). Current is run through the conductive material to toggle portions of the panel on and off in order to manipulate the output. LCD screens, unlike other display technology such as CRT monitors, do not generate their own light and usually require back-lighting–commonly CFL tubes or LEDs–for comfortable use.
