Abstract

A touch screen cover is provided that includes a display filter having a front surface configured to be positioned to at least partially cover a display screen. The display filter has a rim integrally formed with and extending along at least a portion of a perimeter of the front surface of the display filter. The rim projects outward from the front surface away from the display screen. The rim is configured to pass infrared light therethrough along the front surface. The resulting touch screen cover can be watertight and provide a cleanable surface.

Claims

1. A touch screen cover comprising a display filter having a front surface configured to be positioned to at least partially cover a display screen, said display filter having a rim integrally formed with and extending along at least a portion of a perimeter of said front surface of said display filter, said rim projecting outward from said front surface away from the display screen, and said rim being configured to pass infrared light therethrough along said front surface.

2. The touch screen cover of claim 1 further comprising a bezel integrally formed with said rim, said bezel surrounding said display filter and positioned forward of said front surface.

3. The touch screen cover of claim 1 further comprising a printed wire board interior to and surrounding said rim, said printed wire board having infrared elements configured to one of transfer and receive infrared traces through said rim and along said front surface.

4. The touch screen cover of claim 1 further comprising a bezel integrally formed with said rim and a printed wire board snappably mounted to said bezel, said printed wire board having at least one infrared element provided thereon.

5. The touch screen cover of claim 1 further comprising a bezel, said bezel, said rim and said display filter being monolithically formed.

6. The touch screen cover of claim 1 wherein said rim entirely surrounds the perimeter of said front surface of said display filter.

7. The touch screen cover of claim 1 wherein said rim is integrally formed with said front surface of said display filter at a transition area including a predetermined radius of curvature between said rim and said display filter.

8. The touch screen cover of claim 1 wherein said rim forms an infrared lens having inner and outer surfaces angled at a non-orthogonal angle to infrared traces projecting through said infrared lens.

9. The touch screen cover of claim 1 wherein said rim forms an infrared lens having inner and outer surfaces angled substantially perpendicular to infrared traces projecting through said infrared lens.

10. The touch screen cover of claim 1 further comprising an outer bezel integrally formed with said rim, and an inner bezel positioned adjacent said outer bezel.

11. The touch screen cover of claim 1 further comprising an outer bezel integrally formed with said rim, an inner bezel positioned adjacent said outer bezel, and a printed wire board snappably mounted to said inner bezel, such that said inner bezel is positioned between said printed wire board and said outer bezel.

19. The touch screen system of claim 11 further comprising an outer bezel integrally formed with said rim, and an inner bezel positioned adjacent said outer bezel.

20. The touch screen system of claim 11 further comprising an outer bezel integrally formed with said rim, an inner bezel positioned adjacent said outer bezel, and a printed wire board snappably mounted to said inner bezel, such that said inner bezel is positioned between said printed wire board and said outer bezel.

21. The touch screen system of claim 11 wherein said touch screen cover is removably coupled to said display.

12. A touch screen system comprising:

a display comprising a display screen configured to present application specific information;

a touch screen cover coupled to said display, said touch screen cover comprising a display filter having a front surface configured to be positioned to at least partially cover the display screen, said display filter having a rim integrally formed with and extending along at least a portion of a perimeter of said front surface of said display filter, said rim projecting outward from said front surface away from the display screen, and said rim being configured to pass infrared light therethrough along said front surface.

13. The touch screen system of claim 12 further comprising a bezel integrally formed with said rim, said bezel surrounding said display filter and positioned forward of said front surface.

14. The touch screen system of claim 12 further comprising a printed wire board surrounding said rim, said printed wire board having infrared elements configured to one of transfer and receive infrared traces along said front surface.

15. The touch screen system of claim 12 further comprising a bezel integrally formed with said rim and a printed wire board snappably mounted to said bezel, said printed wire board having at least one infrared element provided thereon.

16. The touch screen system of claim 12 further comprising a bezel, said bezel, said rim and said display filter being monolithically formed.

17. The touch screen system of claim 12 wherein said rim is integrally formed with said front surface of said display filter at a transition area including a predetermined radius of curvature between said rim and said display filter.

18. The touch screen system of claim 12 wherein said rim forms an infrared lens having inner and outer surfaces angled at one of (a) a non-orthogonal angle to infrared traces projecting through said infrared lens, and (b) a substantially perpendicular angle to infrared traces projecting through said infrared lens.
