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.

To reduce cost, displays with more than 2 digits are almost invariably constructed using a multiplexed display technique.

Here are the common types of display devices :

Analog electronic displays

Digital electronic displays

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. If the idiot light itself has failed, it will give no indication that it has done so.

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:
