a spacer provided on the back side of the film along the outer perimeter thereof and substantially continuously surrounding the transparent window to prevent trapping dust between the window and touch screen, with the spacer having a thickness sufficient to space the film near but not in contact with the touch screen;

an exposed adhesive on one side of the spacer that faces the touch screen, with the exposed adhesive having sufficient adhesiveness to mount the touch screen protector onto the touch screen 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 front face of the device; and

removably attaching the touch screen protector upon the touch screen of the device via the exposed adhesive to form a space between the transparent window of the film, the spacer and the touch screen portion of the device, wherein the touch screen protector is attached without causing bubble formation or static cling between the transparent window of the film and the touch screen portion of the device;

wherein the transparent window can be pressed against the touch screen portion of the device for operation of the 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.

2. The method of claim 1, wherein the film has a thickness of between 0.5 and 2 mm and includes an opaque band about its periphery that receives the spacer.

3. The method of claim 1, wherein the film also includes micro-particles adhered to the front side of the window in an amount effective for providing anti-glare and anti-static effects to the front side of the window.

4. The method of claim 1, wherein the front face of the device has a non-functional band about its perimeter and the width of the spacer is selected to conform to or be within the band so that the spacer does not interfere with the use of the touch screen portion when the touch screen protector is adhesively mounted onto the device.

5. The method of claim 1, which further comprises providing a backing member to protect the back side of the film and the exposed adhesive prior to use.

6. The method of claim 5, wherein the backing member further includes a tab to assist in the removal of the backing member when mounting the touch screen protector on the device.

7. The method of claim 1, which further comprises providing one or more alignment holes that match one or more buttons on the electronic device to facilitate mounting of the touch screen protector on the device.

8. The method of claim 1, wherein the touch screen of the device and the film are each substantially rectangular and the touch screen is part of a telephone, reading device, music device, viewing device or navigation device.

9. The method of claim 1, wherein the transparent window is clear but includes a coating that provides a matte effect or a privacy screen feature.

10. The method of claim 1, wherein the film is a plastic film.

11. The method of claim 10, wherein the plastic film has a thickness of between 0.15 and 2 mm.

12. The method of claim 1, wherein the space formed between the transparent window of the film, the spacer and the touch screen portion of the device is an enclosed space.

13. The touch screen protector of claim 1, wherein the micro-particles are transparent and cover more than 5% up to 50% of the back side of the film.

14. In a hand held, touch screen electronic device having a front face that includes a touch screen having a touch screen portion and an outer perimeter that is non-functional, the improvement which comprises providing a touch screen protector for the device according to the method of claim 1.

15. The hand held, touch screen electronic device of claim 14, wherein the film is a plastic film.

16. The hand held, touch screen electronic device of claim 15, wherein the plastic film has a thickness of between 0.15 and 2 mm.

17. The hand held, touch screen electronic device of claim 14, wherein the space formed between the transparent window of the film, the spacer and the touch screen portion of the device is an enclosed space.

18. A method for protecting a touch screen of a hand held electronic device having a front face that includes a touch screen having a touch screen portion and a non-functional outer perimeter, which method comprises:

providing a touch screen protector comprising a film having front and back sides, an outer perimeter that essentially corresponds to the outer perimeter of the touch screen of the front face of the device, and a transparent window that essentially corresponds in size to that of the touch screen portion;
