A display device is an output device for presentation of information in visual or tactile form (the latter used for example in tactile electronic displays for blind people). 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

In use

These are the technologies used to create the various displays in use today.

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.
