摘　　要：在光学实验室，采用表面处理不同的两种３０ｃｍＣＲＴ显示器，在画面字符“负性”显示状态下，比较评价了７类ＶＤＴ用滤光屏的光学作用，结果表明：各类滤光屏均可不同程度地提高画面字符的对比度；在降低画面间接眩光方面，则效果不尽一致，有的尚有负面效应。文章认为，从光学效果考虑，ＶＤＴ用户一般无需增置滤光屏。如确有需要，购置时也应注意类别选择。The optical function of seven kinds of VDT filters on 12in CRT displays of 2 surface treatments with negative presentation were compared and estimated.The result shows that the improvement of screen contrast is the same in some degrees for all filters ,but the improvement of reducing reflection is different and even worse for some filters.On the ergonomic consideration,the filter may not be needed in general.If it really needs,the specific filter should be selected.
