摘要
等离子显示器(PDP)的基本工作原理是基于密封在特制的玻璃管中的氦、氙等惰性气体在高电压下产生等离子体,进行放电并放射紫外线激发管壁上的荧光物质发出蓝、绿、红三原色光线构成图像,而图像的颜色和亮度则由经过调制的脉冲电流控制,后者会同时产生电磁波干扰,影响周边环境,本文介绍富士公司开发的一种用传统银盐感光材料制作的电磁波屏蔽膜,可有效地消除PDP工作时产生的不良电磁波。
The basic working mechanism of PDP is based on the behavior of plasma produced by the inert gases,e.g, helium, xenon etc,enclosed in special glass tubes under high voltage inducing an electric discharge and the emission of ultraviolet radiations which stimulate the fluorescent layers coated on the walls of these PDP glass tubes,thus emitting visible light with the three primary colors, i.e. blue, green, red colors, forming the image, whereas the colors and densities of the image are defined by specially modulated pulse currents which produce simultaneously parasite electromagnetic waves interfering the environment. This paper introduced a Fuji shielding film made with traditional silver salts photo material effectively eliminating that electromagnetic interference caused by the performance of PDP.
