liquid crystal display (LCD)A liquid crystal sealed between two pieces of glass with a conductive coating. Liquid crystals normally twist light passing through, but a voltage applied between the glass disrupts the order of the molecules, so that the liquid is darkened and forms visible characters. LCDs have been used in watches, calculators, etc. Related category TECHNOLOGYAlso on this site: Encyclopedia of Alternative Energy & Sustainable Living Encyclopedia of History |
