摘要

介绍了用于多媒体电视(MMTV)的彩色显像管(CPT)平面荫罩的设计方法。同时，冲压模具的曲面形状保持不变，节省了费用，缩短了设计制造周期。25英寸CPT的平面阴影掩模是计算和制造的。新CPT经过组装和测试，其水平分辨率从原来的500行左右提高到700行。无法看到云纹效应。画质很好。

The design of flat shadow mask for improvement definition CPT

The design method of flat shadow mask for CPT (Color Picture Tube) used for MMTV (Multimedia TV) is presented. At the same time, the curved surface shape of stamping mould keeps unchanged, therefore the expense is saved and design and manufacturing period is shortened. The 25 inch CPT's flat shadow mask is computed and manufactured. New CPT is assembled and tested, its horizontal resolution up to 700 lines from original about 500 lines. Moire effect could not be viewed. The picture quality is good.
