电致发光机舱仪表显示屏用发光粉

Electroluminescent Phosphors for Aircraft Cabin Signal Display Screen

新型主战飞机用电致发光屏是一种新型的飞机座舱仪表信号显示屏,是基于电致发光(EL)原理而制作的,用于飞机座舱仪表照明显示。电致发光屏是为了解决飞机座舱仪表传统照明的不足而研制的第三代照明系统,这种发光屏不需外光源,直接将电能转化为光能进行显示,成功地解决了荧光显示和灯珠显示的诸多问题。电致发光,主要是在以ZnS等为基质的半导体材料中加入少量Cu、Mn等激活剂后在电场作用下发光。这种发光,作为一种固体冷光源在发光与显示领域得到了广泛的应用。国产系列飞机座舱信号显示屏成功地应用了电致发光技术,本文就电致发光屏所用发光粉的研制及性能进行了介绍和分析。

The electroluminescent phosphors are the important materials of new type cabi n signal display EL screen used for displaying the data of the main battle aircraft. The electroluminescent phosphors are the thirdgeneration illuminatio n system which is designed to complete ins trument data for the traditional one. The new screen can change electrical energ y directly into optical energy and works without external luminous source, it is the successfu l solution to many problems lying in the fluorescent display and the bead lamp d isplay. 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 s o urce, EL has gained wide application in the luminaire and display fields We ap p ly successfully the EL display panel in a series aircraft cabin signal display s creen.
