electroluminescent display (ELD)
Last modified: Thursday, March 11, 2004
A technology used to produce a very thin display screen, called a flat-panel display, used in some portable computers. An ELD works by sandwiching a thin film of phosphorescent substance between two plates. One plate is coated with vertical wires and the other with horizontal wires, forming a grid. When an electrical current is passed through a horizontal and vertical wire, the phosphorescent film at the intersection glows, creating a point of light, or pixel.
Other types of flat-panel displays include LCD displays and gas-plasma displays, both of which are more common than ELDs.
