Film-margin adjuster

Abstract

A film-margin adjuster, including: four shielding plates, for shielding an area of the peripheral edge-portions of a film-formation substrate respectively; the four shielding plates are oppositely disposed in pairs, and at least one pair of the oppositely disposed shielding plates has a adjustable relative distance therebetween. The film-margin adjuster, by virtue of the at least one pair of the oppositely disposed shielding plates having an adjustable relative distance therebetween, can adjust the area of the peripheral edge-portions of the film-formation substrate shielded by the shielding plates, thus achieving adjustment of the size of film-margin, and improving yield of production line.
