  • METHOD FOR LOCALLY FORMING SMOOTH SURFACE ON FROSTED GLASS
    Publication number: 20130236645
    Abstract: A method for locally forming a smooth surface on frosted glass includes steps of: a) preparing a piece of frosted glass; b) locally coating the frosted glass with a sealant; and c) such forming the sealant that has a smooth surface. The smooth surface of the frosted glass allows a video camera to capture clear images therethrough so as to prevent blurred images caused by micro-roughness on a surface of the frosted glass.
