| 摘 要： | 地球存在着地磁场,地磁场对彩色显像管(CPT)的色纯度影响很大.为了减小地磁场对CPT色纯度的影响,通常在CPT内部装有磁屏蔽组件(简称为内屏蔽).本文介绍一种无内屏蔽组件的CPT,它既降低了CPT的成本,又不影响CPT的品位,还能满足全球地磁场的兼容性.

| Abstract: | The geomagnetic-fields on the earth have great influence on the color pure of CPT. Generally, the magnetism shield assembled in CPT can eliminate the influence of geomagnetic-filed for the color pure of CPT. In this paper we introduce a CPT without shield, which can both reduce cost and keep in high quality. Yet it is capable of satisfy the compatibility of global geomagnetic-field. |
