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 is supplied as an electrical signal, the display is called an electronic display.
Common applications for electronic visual displays are televisions or computer monitors.

Segment displays
Digital clocks display changing numbers.
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. There are several types:
The common segment displays shown side by side: 7-segment, 9-segment, 14-segment and 16-segment displays.
- Seven-segment display (most common, digits only)
- Fourteen-segment display
- Sixteen-segment display
- HD44780 LCD controller a widely accepted protocol for LCDs.
Underlying technologies
- Incandescent filaments
- Vacuum fluorescent display
- Cold cathode gas discharge
- Light-emitting diode (LED)
- Liquid crystal display (LCD)
- Physical vane with electromagnetic activation
Full-area 2-dimensional displays
2-dimensional displays that cover a full area (usually a rectangle) are also called video displays, since it's the main modality of presenting video.
Applications
Full-area 2-dimensional displays are used in, for example:
- Television sets
- Computer monitors
- Head-mounted display
- Broadcast reference monitor
- Medical monitors
Underlying technologies
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)
- Surface-conduction electron-emitter display (SED) (experimental)
- Laser TV (forthcoming)
- Carbon nanotubes (experimental)
- Quantum dot display (experimental)
- Interferometric modulator display (IMOD)
The multiplexed display technique is used to drive most display devices.
Three-dimensional
- Swept-volume display
- Varifocal mirror display
- Emissive volume display
- Laser display
- Holographic display
- Light field displays
Further information: Volumetric display
Mechanical types
- Ticker tape (historical)
- Split-flap display (or simply flap display)
- Flip-disc display (or flip-dot display)
- Rollsign
- Tactile electronic displays (aka refreshable Braille display) 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.
- Idiot lights, the "Check Engine" light on an automobile dashboard is the quintessential idiot light, giving only the information that something is amiss, but not what particular subsystem or component, nor how urgent the problem is. Neither does it give any information about issues that may be still within acceptable limits, but trending towards failure.
