Have you ever wondered how an LCD TV works? Just what are liquid crystals, and how do they create the wonderful colour image we see on our screens?
LCD is short for Liquid Crystal Display. These tiny “liquid crystals” which make up the image are not really liquid as such, but their behaviour is more like that of a liquid than a solid. They are sort of a half-way point between the two states. They are solid in that they are able to stay in one place, but liquid-like in their ability to change shape.
