Display device
Encyclopedia : D : DI : DIS : Display device
A display device 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 :
- CRT display (earlier)
- Electronic paper
- Nixie tube displays (now obsolete)
- VF display
- LED displays (later)
- PDP
- LCD (most recent)
- *HPA display
- *TFT display
- Electronic ink
- OLED (forthcoming)
- SED (forthcoming)
- Carbon nanotubes (experimental)
- Nanocrystal displays (experimental)
- Film projectors
- *Movie projector
- *Slide projector
- Digital projectors
- *Digital projector
Mechanical types
- Ticker tape (historical)
- Flap display or split-flap display (see talk page)
- Disc-flap display
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. There are several types:
- Seven segment display (most common, digits only)
- Fourteen segment display
- Sixteen segment display

- rollsign, the precursor to digital displays on public transportation
