LCD

Noun Abbreviated Form A type of display that uses a liquid compound having a polar molecular structure, sandwiched between two transparent electrodes. When an electric field is applied, the molecules align with the field, forming a crystalline arrangement that polarizes the light passing through it. A polarized filter laminated over the electrodes blocks polarized light. In this way, a grid of electrodes can selectively ""turn on"" a cell, or a pixel, containing the liquid crystal material, turning it dark.
