Touch screen protector
A touch screen protector is removably attachable to a touch screen device. The protector attaches to the touch screen device about an outer peripheral portion of the touch screen, thereby not adhering to a central video display portion of the touch screen. The protector is pre-formed with a curvature that causes the protector, when attached to the device, to rise upwards and away from the touch screen. By biasing the protector away from the touch screen, the attached protector inhibits optical interference forming between the protector and the touch screen. The curvature is configured to provide a separation that is large enough to inhibit formation of optical interference between the protector and the touch screen, but small enough to maintain touch sensitivity of the touch screen.
1. A protector for a touch screen device, the device having a touch screen that includes an active area with a touch sensitive visual display and an inactive area, the protector comprising:
a base layer having a shape that corresponds to the touch screen;
an adhesive layer applied to an interior side of the protector, the adhesive layer surrounding a central portion of the protector so that no adhesive is applied on the interior side of the central portion of the protector, the protector having a shape that corresponds to the shape of the visual display;
wherein the protector is configured to attach to the touch screen of the device so that the adhesive layer of the attached protector at least partially surrounds the visual display of the active area, and so that the attached protector covers the touch screen without the central portion of the protector adhering to the visual display of the active area, and
wherein the protector consists of flexible film material, the protector is pre-formed with a curvature so that the central portion of the protector deflects off the visual display by a distance large enough to avoid formation of optical interference when at rest and flexes so that the central portion of the protector contacts the touch screen device to maintain touch sensitivity when manipulated by a user using normal operation forces.
2. The protector of claim 1 , wherein the pre-formed curvature is curved about a longitudinal axis of the protector.
3. The protector of claim 1 , wherein the protector is configured so that the central portion of the attached protector deflects off the visual display by a distance large enough to avoid formation of optical interference, and small enough to maintain touch sensitivity of the touch screen through the attached protector.
4. The protector of claim 1 , wherein the protector is configured so that the central portion of the attached protector is between about 3 microns and about 400 microns off the visual display when the device is not in operation.
5. The protector of claim 1 , wherein the curvature is formed via a molding process.
6. The protector of claim 1 , wherein the preformed curvature is formed via a controlled industrial thermo-molding process.
7. The protector of claim 1 , wherein pre-formed curvature is formed by wrapping the protector around the outer diameter of a tube, cylinder, partial-tube, or partial-cylinder.
8. The protector of claim 1 , wherein pre-formed curvature is formed by rolling and inserting the protector into a tube or cylinder.
9. The protector of claim 1 , wherein the pre-formed curvature is formed by rolling or partially rolling the protector and maintaining the protector in a rolled or partially rolled position using a holding device.
10. The protector of claim 7 , wherein the pre-formed curvature is further formed by maintaining the protector in the wrapped configuration for at least 2 hours.
11. The protector of claim 7 , wherein the pre-formed curvature is formed by rolling or partially rolling the protector along the longitudinal axis of the protector.
12. The protector of claim 7 , wherein the pre-formed curvature is formed by rolling or partially rolling the protector to a diameter of between about 1.5 inches and about 2.5 inches.
13. The protector of claim 1 , wherein the attached protector inhibits formation of undesirable optical effects with respect to the visual display.
14. The protector of claim 1 , wherein the attached protector inhibits formation of undesirable optical effects without including objects on the base layer that may affect transparency, clarity, or visibility through the protector.
15. The protector of claim 1 , wherein the attached protector inhibits formation of undesirable optical effects without applying a coating to the interior surface of the protector.
16. The protector of claim 1 , wherein the adhesive layer is applied about two opposing edge areas of the protector, wherein the adhesive applied about the two opposing edges serve as fixed rails that inhibit lateral movement of the protector edges when the protector is pressed.
17. The protector of claim 1 , wherein the touch screen has a curved surface, and wherein the protector is configured to mount to the curved touch screen surface.
