The electroluminescent phosphors are the important materials of new type cabin signal display EL screen used for displaying the data of the main battle aircraft. The electroluminescent phosphors are the third-generation illumination system which is designed to complete instrument data for the traditional one. The new screen can change electrical energy directly into optical energy and works without external luminous source

it is the successful solution to many problems lying in the fluorescent display and the bead lamp display. Electroluminescence is based on the semiconductor material such as ZnS doped with Cu and Mn drove by electric field. As a kind of solid cold light source

EL has gained wide application in the luminaire and display fields. We apply successfully the EL display panel in a series aircraft cabin signal display screen.
