Touch screen protector

摘要

The invention relates to a touch screen protector for a hand held electronic device having a front face that includes a touch screen portion and a non-functional band. The touch screen protector of the invention comprises a plastic film having front and back sides, an outer perimeter that corresponds to that of the device, and a transparent window; a spacer provided along the outer perimeter of the plastic film surrounding the transparent window, having a thickness sufficient to space the plastic film near but not in contact with the touch screen portion; an exposed adhesive for removably mounting the protector upon the outer perimeter of the front face to form an enclosed air space between the transparent window of the plastic film, the spacer and the touch screen portion of the device; and a joining adhesive for adhering the spacer to the back side of the plastic film.

主权项

1. A touch screen protector for a hand held electronic device having a front face that includes a touch screen having a touch screen portion and a non-functional band, the touch screen protector comprising:
a film having front and back sides, an outer perimeter that corresponds to that of the touch screen of the front face of the device, and a transparent window that corresponds in size to the touch screen portion; micro-particles present on the back side of the film at a density which is sufficiently high to prevent interference patterns and to provide an anti-static effect between the film and touch screen portion without adversely affecting quality of images viewed through the window; a spacer provided on the back side of the film along the outer perimeter of the film surrounding the transparent window, having a thickness sufficient to space the film near but not in contact with the touch screen portion, an exposed adhesive on one side of the spacer for removably mounting the protector upon an outer perimeter of the touch screen and having a thickness sufficient to space the film near but not in contact with the touch screen to form an air space between the transparent window of the film, the spacer and the touch screen portion of the device, wherein the exposed adhesive has an adhesive strength of 5-50 grams to releasably mount the protector onto the device and to enable its removal without leaving adhesive residue on the touch screen; and a joining adhesive for adhering the spacer to the back side of the film, wherein the joining adhesive has an adhesive strength that is stronger than that of the exposed adhesive so that the spacer is not removed from the film when the protector is removed from the touch screen of the front face of the device; wherein the window can be pressed against the touch screen portion for operation of the electronic device while preventing direct contact of a user's fingers with the touch screen portion of the device and without generating static cling between the film and touch screen portion or producing visible interference patterns during use.
