When light inputs the surface of optical elements, there is reflection as well as refraction, so ghost light come into being, its focus is called ghost image.
光学元件表面在折射时都存在反射,从而存在设计意图之外的杂散光,其会聚点即所谓鬼点。
Note: the "ghost" refers to the working voltage Angle of 60 degrees (to display the surface as the base) should not be displayed on the LCD display Dan vaguely.
注:“重影”指在工作电压下60度视角(以显示面为基准)液晶不该显示的段位隐约显示。
