flat-panel display

Display devices convey information in visible form from electronic devices to human viewers. Common examples are the faces on digital watches, numerical indicators on stereo equipment, and the picture tubes in television sets and computer monitors. Until recently the most versatile of these…

… (CRT) and the more recent flat-panel display. In CRT displays an electron gun emits beams of electrons on a phosphorus-coated surface; the beams are deflected, forming visible patterns representative of data. Flat-panel displays use one of four different media for visual representation of data: liquid crystal, light-emitting diodes, plasma panels,…

…been, however, considerable improvements in flat-panel displays because of the demands of computers and television. Flat-panel displays occupy less volume and require less power than CRTs, but they also have their limitations. Radar has taken advantage of flat-panel displays and has become increasingly important as a display.

…also is used in high-resolution flat-panel displays for computer monitors and for television screens. In such applications the large-area amorphous-semiconductor thin film is etched into an array of many tiny units, each of which forms the active element of a transistor that electronically turns on or off a small pixel…
