Glass Screen Protector with Adhered Print, Process for Authenticating a Maker of Glass Screen Protector with Ultraviolet Ink, and Screen Protector for Decorating a Powered-off Display

摘要

A glass screen protector with a logo printed beneath the exterior surface of the glass protects an underlying screen and displays the logo for decorative and branding purposes. In addition, a method is taught for printing on the glass screen protector. The printable glass, and method are created through layering method combine multiple layers in order to create a uniform printable glass, absent bubbling, with the printed medium subsurface. An additional polyethylene terephthalate/optically clear adhesive/printed logo laminate is included behind a glass layer to provide a screen protector with a custom printed logo that does not interfere with touchscreen use or lead to bubbling in the screen protector. A printed logo made of pigments that are viewable in visible light can be placed over a part of a device's screen that is not used to display information from the device. A printed logo of ultraviolet visible ink that is transparent in visible light can be used to authenticate a screen protector as being made by a particular manufacturer. A layer of one-way printing can be used to create a screen protector that shows the one-way printing when the protected screen is not in use and that shows the screen that is unobstructed when the protected screen is powered on and in use.
