在液晶显示器件的表面处理中,Janning[1]首创了倾斜蒸发一氧化硅(SiO)的方法而获得了向列液晶的均匀排列.当斜蒸角(蒸发束与基片平面所成的角)小于15°时,得到的是大于20°的高倾角排列;而当蒸发角在15—45°之间时,液晶指向矢的倾角为0°[2].实验证明这两种情况都不适应多路驱 In the surface treatment of liquid crystal display devices, Janning [1] pioneered the method of oblique evaporation of silicon monoxide (SiO) to obtain uniform alignment of nematic liquid crystals. When the skew angle (the angle between the evaporation beam and the plane of the substrate ) Is less than 15 °, a high tilt angle of more than 20 ° is obtained, and when the evaporation angle is between 15 and 45 °, the tilt angle of the liquid crystal director is 0 °. Experiments show that neither of these two cases Adapt to multi-channel drive
