Electroluminescent Display

What Does Electroluminescent Display Mean?

An electroluminescent display is a category of flat panel display created by
sandwiching a thin film of electroluminescent material between two plates. An electroluminescent display makes use of the phenomenon of electroluminescence. Although electroluminescent displays are not as commonly used as other display types, they are used in industrial, instrumentation and transportation applications.


Techopedia Explains Electroluminescent Display

Electroluminescent devices are similar in many ways to capacitors.The only difference between them is the phosphor layer used in electroluminescent displays. The electroluminescent display is constructed with the help of flat opaque electrode strips which are kept parallel to each other and which are covered by one layer of electroluminescent material such as phosphorus, and then by another layer of electrodes which are perpendicular to the layer at the end.

In electroluminescent displays, the atoms are moved to an excitation state with the help of electric current. This results in radiation being emitted in the form of visible light. By varying excitation level of atoms, the color displayed can be changed in the electroluminescent display. Alternating current is normally used for operating an electroluminescent display. One of the salient features of an electroluminescent display is that it provides a wide viewing angle as well as a clear and sharp image. Most electroluminescent displays are monochromatic.
