ABSTRACT:
A plastic film screen protector that prevents interference patterns from arising when the film touches the screen is described. The advantages are accomplished by the film having a slightly roughened surface so that the majority of the film facing an electronic device screen does not substantially touch the screen. These physical aberrations prevent Newton ring interference patterns and spots caused by refractive index differences between air and the film material.
