A '''display''' is a piece of [[hardware]] which can display an image to the [[user]]; the may be monochrome, although now they are almost all colour.

The first displays used [[cathode ray tube|CRTs]], but since they were [[vacuum tube]]s, they took up considerable volume. Still, they were the mainstay of visual displays up through the early days of [[bit-mapped display]]s.

When it became possible to fabricate [[liquid crystal display]]s with many [[pixel]]s in large [[array]]s, they were the only viable display technology for use in lap-top [[personal computer]]s, and that drove their development. LCD displays rapidly became the display of choice once they became economically competive.

LCDs needed a backlight, which was generally provided by a fluorescent light driven by a high-[[voltage]] [[power supply]], both of which had a tendency to fail.
