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.
Claims29
A method for protecting a screen of an electronic device, comprising the step of contacting a replaceable protective film that includes a roughened coating that contacts the surface of the electronic screen and includes a smooth side for contact with a stylus, wherein the protective film is slidably contacted to the surface of the electronic screen, whereby the protective film suppresses formation of Newton rings when the film is installed in contact upon the screen.
