Quick Reference

1 A device that can be attached to a computer in order to present transient images — textual or pictorial — on its screen (see text mode, graphics mode). For many years the most widely used display device was the cathode-ray tube with color specified by RGB signals. Other display technologies use flat-panel displays, which in recent years have largely replaced cathode-ray tubes as prices have fallen. These include LCDs (liquid-crystal displays), plasma panels, and electroluminescent displays.

2 A method of presenting graphical or pictorial images. See raster-scan display, vector display.

3 To make information visible in a temporary form.
