==== Segment displays ====

[[File:Common segment displays.svg|right|thumb|The common segment displays shown side by side: [[Seven-segment display|7-segment]], [[Nine-segment display|9-segment]], [[Fourteen-segment display|14-segment]] and [[Sixteen-segment display|16-segment]] displays]]
Some displays can show only [[numerical digit|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 [[LED]]s or [[LCD|liquid crystals]]. They are mostly used in [[digital watch]]es and [[pocket calculator]]s. Common types are [[seven-segment display]]s which are used for numerals only, and alphanumeric [[Fourteen-segment display|fourteen-segment displays]] and [[sixteen-segment display]]s which can display numerals and Roman alphabet letters.

=== Other types ===
* [[Vacuum fluorescent display]]
* [[Electroluminescent display|Electroluminescent (ELD) display]]
* [[Plasma display|Plasma (PDP) display]]
* [[Laser-powered phosphor display]]

[[Cathode-ray tube]]s 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:
* [[Television set]]
* [[Computer monitor]]
* [[Head-mounted display]]s, [[Heads-up display]]s and [[Virtual reality headset]]s
* [[Broadcast reference monitor]]
* [[Medical monitor]]s
* [[Mobile display]]s (for [[mobile devices]])
* [[Comparison of high-definition smartphone displays|Smartphone displays]] (for [[smartphones]])
* [[Video wall]]s

===== Underlying technologies of full-area 2-dimensional displays =====
Underlying technologies for full-area 2-dimensional displays include:
* [[Cathode-ray tube]] display (CRT)
* [[LED display|Light-emitting diode display]] (LED)
* [[Electroluminescent display]] (ELD)
* [[Electronic paper]], [[E Ink]]
* [[Plasma display]] panel (PDP)
* [[Liquid-crystal display]] (LCD)
** [[High-performance addressing]] display (HPA)
** [[Thin-film transistor]] display (TFT)
* [[Organic light-emitting diode]] display (OLED)
* [[Digital Light Processing]] display (DLP)
* [[Surface-conduction electron-emitter display]] (SED) (experimental)
* [[Field-emission display]] (FED) (experimental)
* [[Laser TV]] (forthcoming)
* [[Carbon nanotube]]s (experimental)
* [[Quantum dot display]] (QLED)
* [[Interferometric modulator display]] (IMOD)
* Digital microshutter display (DMS)
* [[microLED]] (in development)

The [[multiplexed display]] technique is used to drive most display devices.

==== Three-dimensional displays ====
* [[Swept-volume display]]
* [[Laser display]]
* [[Holographic display]]
* [[Light field display|Light field displays]]
* [[Andotrope]]
