Common applications for ''[[electronic visual display]]sdisplays'' are [[television set]]s or [[computer monitor]]s.

Line 81 ⟶ 85:
* [[Split-flap display]] (or simply [[flap display]])
* [[Flip-disc display]] (or flip-dot display)
* [[Vane display]]
* [[Destination sign#Rollsign|Rollsign]]
* [[Refreshable Braillebraille display|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.
