AC thin film electroluminescent display devices

augmented reality

Augmented reality (AR) is a technology that integrates digital information, typically in the form of computer-generated graphics, images, or data, with the real-world environment in real-time. AR...

blinking

Intentionally alternating the intensity of a display element in a graphic display device.

electroluminescent display

The utilization of the light produced when electrical energy is directly converted into light within devices used for visual readout displays or as complex logic-circuit elements. With EL lighting,...

flat panel display

An electronic display in which a flat screen is formed by an orthogonal array of display devices, such as electroluminescent devices, light-emitting diodes or liquid crystal cells.

gas discharge display

A display device that contains an inert gas that gives off orange light when a high voltage is applied to ionize the gas.

picture element -> pixel

A pixel, short for "picture element," is the smallest controllable element of a digital image or display. It is a fundamental unit that represents a single point in a raster image, which is a grid of...

pixel

remote display unit

A display device, such as a cathode-ray tube, that is located at some distance from the source generating the displayed information.

thermoplastic recording device

A display device having a thermoplastic film as the control layer medium. The film, moving from a playoff reel, is scanned by an electron gun and melted by an RF heating unit. Deformation of the film...

video graphics array

A display standard no longer in use and originally defined for IBM PCs, with 640 3 480 pixels in 16 colors and a 4:3 aspect ratio. There is also a text mode with 720 3 400 pixels. The standard has...
