Waterproof user interface display panels

1. A waterproof user interface panel comprising:

a display touch or presence-sensitive assembly including:

an electronic display;

a presence-sensitive layer; and

a rigid transparent or translucent cover layer overlying a top surface of the presence-sensitive layer;

a housing for said assembly, the housing including a cutout or window area; and

a peripheral edge of the cover layer secured to said housing at a peripheral region surrounding the cutout area to prevent moisture intrusion into said housing through the cutout area; and wherein:

said housing includes an upper housing and a lower housing, the cutout area or window being formed in the upper housing, with said assembly located in said upper housing and adjacent the cutout area of the upper housing, the lower housing having a bottom surface and a peripheral sidewall defining a housing cavity;

sealing material located in the lower housing having a sealing material top surface above the bottom surface of the lower housing;

said upper housing including a peripheral protrusion surrounding the cutout or window area and which extends into the housing cavity in the lower housing and penetrates the sealing material in the lower housing when said upper and said lower housings are assembled such that a portion of the protrusion is embedded in the sealing material to form a waterproof seal to protect a back side of said assembly from external moisture.

2. The interface panel of claim 1 , wherein said cover layer is a chemically strengthened glass layer.

3. The interface panel of claim 1 , further comprising:

a circuit board secured to the lower housing and electrically coupled to the display presence-sensitive assembly, the sealing material covering the circuit board.

4. The interface panel of claim 3 , wherein said lower housing has protrusions to hold said circuit board in a fixed position relative to said lower housing.

5. The interface panel of claim 1 , wherein the sealing material is a gel material.

6. The interface panel of claim 1 , wherein the lower housing has standoff protrusions configured to contact and support the cover layer when said upper and said lower housings are assembled.

7. The interface panel of claim 1 , further comprising an O-ring seal disposed between surfaces of the upper housing structure and the lower housing structure when the upper and lower housing structures are assembled together.

8. The interface panel of claim 1 , wherein the peripheral edge of the cover layer is secured to the upper housing structure by an adhesive layer.

9. The interface panel of claim 1 , wherein said presence-sensitive layer is responsive to changes in capacitance resulting from touching or close proximity of an object to the layer.

10. The interface panel of claim 1 , wherein the peripheral edge of the cover layer is secured to a back surface of the upper housing structure.

11. The interface panel of claim 1 , wherein said panel is configured for use with a bathing installation and for mounting in an opening of a wall of a bathing installation tub, and wherein the housing includes a peripheral flange portion for mounting to a tub wall surface surrounding the opening, the panel display configured to display information to the bathing installation user, the panel including controls configured to allow the bathing installation user to control features of the bathing installation.

12. The interface panel of claim 1 , wherein said panel is configured for use with a bathing installation and for mounting in an opening of a wall of a bathing installation tub, and wherein the housing includes a peripheral flange portion for mounting to a tub wall surface surrounding the opening, the panel display configured to display information to the bathing installation user, the panel including controls configured to allow the bathing installation user to control features of the bathing installation.

13. A user interface panel comprising:

an electronic display;

a presence-sensitive screen positioned over and secured to said electronic display to form a display/presence-sensitive screen assembly responsive to sensed changes in capacitance at areas of an active region of the assembly;

a housing structure comprising an upper housing and a lower housing, the upper housing including a cutout area;

said assembly located in said upper housing and adjacent the cutout area of the upper housing, the housing structure having a bottom surface and a peripheral sidewall defining a housing cavity;

a rigid transparent or translucent cover layer overlying a top surface of the presence-sensitive screen and bonded to said top surface, and wherein a peripheral edge of the cover layer is secured to said housing structure at a peripheral region surrounding the cutout area to prevent moisture intrusion into said housing through the cutout area;

sealing material located in the housing cavity;

said upper housing including a peripheral protrusion surrounding the cutout area and which extends into the housing cavity and penetrates the sealing material such that a portion of the protrusion is embedded in the sealing material to form a waterproof seal to protect a back side of said assembly from external moisture.

14. The interface panel of claim 13 , further comprising:

a circuit board secured to the lower housing and electrically coupled to the presence-sensitive panel and to the electronic display, the sealing material covering the circuit board.

15. The interface panel of claim 13 , wherein the sealing material is a gel material.

16. The interface panel of claim 13 , wherein the peripheral edge of the cover layer is secured to a back surface of the upper housing structure.
