Liquid Crystal Display ("LCD")

A liquid crystal display ("LCD") is a type of electronic passive or active matrix semiconductor technology to display a message or image. A liquid crystal display employs an array of segments called pixels which can be manipulated by the application of a very low voltage to change the orientation of a substrate of crystal molecules.

Modern liquid crystal displays incorporate multiple layers, one of which is a light source to illuminate the image being created by the orientation of the crystals. Overlaying various additional layers including colour filters (red, green and blue) enable a liquid crystal display to display colour.
