About Industrial Computer Monitors
Industrial computer monitors are ruggedized for use in control room, factory floor, and processing environments. There are two basic types of products: cathode ray tube (CRT) monitors and flat panel displays (FPD). CRTs are sealed, glass tubes that generate light from an electron beam. The beam is produced by the acceleration of electrons from a heated cathode and grid towards the front surface of the screen. The surface on the back of the screen is coated with phosphors that light up when struck by the electron beam. Flat panel displays (FPD) are thin, flat, industrial computer monitors that are often used in notebook computers. There are three main types of FPDs: liquid crystal displays (LCD), plasma displays, and electroluminescent displays (ELD). LCDs use two sheets of polarizing material with a liquid crystal solution between them. In a plasma display, a gas fills the spaces between two glass sheets that are lined up in parallel and separated by a gap just 100 to 200 microns wide. ELDs sandwich a thin film of phosphorescent substance between two plates.
