Some displays can show only digits or alphanumeric characters. They are called segment displays, because they are composed of several segments that switch on and off to give appearance of desired glyph. The segments are usually single LEDs or liquid crystals. They are mostly used in digital watches and pocket calculators. Common types are seven-segment displays which are used for numerals only, and alphanumeric fourteen-segment displays and sixteen-segment displays which can display numerals and Roman alphabet letters.

= Other types =

Cathode-ray tubes were also formerly widely used.

== Full-area 2-dimensional displays ==

2-dimensional displays that cover a full area (usually a rectangle) are also called video displays, since it is the main modality of presenting video.

=== Applications of full-area 2-dimensional displays ===

Full-area 2-dimensional displays are used in, for example:
