Nixie-tubes, LED-display and VF-display |
A
display device, also known as an
information display is a device for visual or tactile presentation of
images (including text) acquired, stored, or transmitted in various forms. While most common displays are designed to present information dynamically in a visual medium, tactile displays, usually intended for the blind or visually impaired, use mechanical parts to dynamically update a tactile image (usually of text) so that the image may be felt by the fingers.
Here are the common types of display devices :
Analog electronic displays

Disc-flap displaySome 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 . They are mostly used in
digital watches and
pocket calculators. There are several types:
*
Seven segment display (most common, digits only)
*
Fourteen segment display*
Sixteen segment display*
computer display *
graphical output device*
television*
Times Square, where numerous display devices can be seen in use
*
rollsign, the precursor to digital displays on
public transportation*
