扁平显像管中荧光面杂乱发光现象探讨

A Study of Disorder Luminescence on Fluorescent Screen of FCRT

扁平显像管是世界上研制多年的显示器件，其研制难点之一是消除荧光屏上出现的失控的杂散发光对画面的影响。本文分析了扁平管的结构与工作状态和荧光面杂散发光的关系，讨论了可能引起杂散发光的因素，提出了消除荧光屏杂散发光的一些办法。

Flat cathode ray tube (FCRT) is a display device studied for many years over the world.One of the difficulties in research is to eliminate the disorder luminescence that cannot be controlled and affects the frame on the fluorescent screen.In this paper the relationship between structure,working condition of FCRT and disorder luminescence on the fluorescent screen is analyzed.The reasons that causes the disorder luminescence are discussed.Some methods that eliminate the disorder luminescence on fluorescent screen are presented.
