Touch screen saver

Abstract

A shield that is attachable to a touch sensitive screen is disclosed. The shield may be attached to the touch sensitive screen only at its outer peripheral portion. An air gap is enclosed between the shield and the touch sensitive screen to form a planar air bearing. The shield preferably does not touch the active area of the touch sensitive screen when the user is not touching the shield but only viewing the touch sensitive screen through the shield. This mitigates unwanted optical artifacts such as trapped air bubbles, Newton rings and chromatic interference while maintaining the sensitivity of the touch sensitive screen.

         23 . A method for forming a shield for a touch sensitive screen of an electronic device, the method comprising the steps of:
 nipping first and second films together;   cutting out a central portion of the first and second films for providing an air gap when the shield is mounted to the touch sensitive screen of the electronic device; and   nipping a third film to the first and second films.   
     
     
         24 . The method of  claim 23  wherein the first and second films are a protective liner and an opaque film, respectively, and the opaque second film hides air bubbles that may form when the shield is mounted to the touch sensitive screen of the electronic device. 
     
     
         25 . The method of  claim 24  wherein the third film is a protective film for mitigating scratches on the touch sensitive screen. 
     
     
         26 . The method of  claim 24  further comprising at least one sacrificial layer adhered to the third film.
