    • An advanced video display terminal (VDT) screen shielding method and apparatus includes an electric resistance lower than or equal to 10.sup.5 .OMEGA.(R.ltoreq.10.sup.5 .OMEGA.), a transmittance between 1/3 to 2/3, a fiber diameter D.ltoreq.MIN(D.sub.1,D.sub.2). Wherein D.sub.1 =VD.times.25.4.times.0.8/RV.times.0.16 or D.sub.1 =VD.times.25.4.times.0.6/RH.times.0.16, D.sub.2 =VD.times.PA.sup.3 -QA.sup.2 +RA-S, P=1.342.+-.0.002, Q=2.032.+-.0.002, R=1.011.+-.0.002, S=0.116.+-.0.002 and the aperture is a circle, ellipse, polygon, square or other transfigure. A formed angle .ltoreq.45.degree. of the fabric is horizontally against cathode ray tube. This screen-shielding method could suitably reduce glare and reflected lights, eliminate electrostatic charges and low frequency radiation, and prevent Moires and/or Newton Rings. This screen-shielding apparatus includes a frame, the high conductive fabric and a suitable ground wire, and is installed in front of the surface of the CRT.
    • 先进的视频显示终端(VDT)屏幕屏蔽方法和装置包括低于或等于105欧姆(R 欧米茄)的电阻,透光率在1/3至2/3之间,光纤直径D < = MIN(D1,D2)。 其中D1 = VDx25.4x0.8 / RVx0.16或D1 = VDx25.4x0.6 / RHx0.16,D2 = VDxPA3-QA2 + RA-S,P = 1.342 +/- 0.002,Q = 2.032 +/- 0.002 ,R = 1.011 +/- 0.002,S = 0.116 +/- 0.002,孔径为圆形,椭圆形,多边形,正方形或其他变形。 织物的形成角度
