Electronic Visual Displays

A display device is an output device for presentation of information for visual or tactile reception, acquired, stored, or transmitted in various forms. When the input information is supplied as an electrical signal, the display is called "electronic display". "Electronic displays" are available for presentation of visual and tactile information.

Tactile electronic displays are usually intended for the blind or visually impaired. They use electro-mechanical actuators to dynamically update a tactile image (usually of text) so that the image may be felt by the fingers ("refreshable Braille display").

Common applications for "electronic visual displays" used to be television sets or computer monitors, but these days "electronic visual displays" tend to be ubiquitous as interface for large amounts of visual information in mobile computing applications and portable IC devices.

Classification

Electronic visual displays generate visual information according to the electrical input signal (analog or digital) either by generation of light (then they are called "active displays") or, alternatively, by modulation of available light during the process of reflection or transmission (light modulators are called "passive displays").

Generation and Control of Colors

Colors can be generated by selective emission, by selective absorption, transmission or by selective reflection.
