小型彩色显示管荫罩曲面设计

Design of the Curved Surface of Mask for Small Color Display Tubes

介绍一种简单而实用的荫罩曲面的计算方法。首先根据荫罩组件在彩色显示管中的工作原理 ,提出荫罩曲面计算的经验公式 ,然后对该公式求导 ,得出荫罩曲面的修正公式 。

This paper introduce a simple and practical calculating method for the curved surface of mask. Base on mask's working principles in color display tubes,the experience formulas for calculating the curved surface of mask are proposed. Then,by the derivaton of the formulas,a correct formula for the curved surface of mask can be obtained, and finally a complete design of the curved surface of mask is also presented.
