Script error: No such module "anchor".A display device is an output device for presentation of information in visual[1] or tactile form (the latter used for example in tactile electronic displays for blind people).[2] When the input information that is supplied has an electrical signal the display is called an electronic display.
Common applications for electronic visual displays are television sets or computer monitors.
Types of electronic displays
Script error: No such module "Labelled list hatnote".
In use
These are the technologies used to create the various displays in use today.
Segment displays
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
- Vacuum fluorescent display
- Electroluminescent (ELD) display
- Plasma (PDP) display
- Laser-powered phosphor display
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:
- Television set
- Computer monitor
- Head-mounted displays, Heads-up displays and Virtual reality headsets
- Broadcast reference monitor - Industry/non-common consumer directed hardware/equipment.
- Medical monitors
- Mobile displays (for mobile devices)
- Smartphone displays (for smartphones)
- Video walls
Underlying technologies of full-area 2-dimensional displays
Underlying technologies for full-area 2-dimensional displays include:
- Cathode-ray tube display (CRT)
- 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 nanotubes (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

Mechanical types
- Ticker tape (historical)
- Split-flap display (or simply flap display)
- Flip-disc display (or flip-dot display)
- Vane display
- Rollsign
- Tactile electronic displays are usually intended for the blind. They use electro-mechanical parts to dynamically update a tactile image (usually of text) so that the image may be felt by the fingers.
- Optacon, using metal rods instead of light in order to convey images to blind people by tactile sensation.
