Abstract

A display assembly for a portable module is disclosed. The display assembly has a housing that includes a base portion and a continuous side portion extending from the base portion to define an interior compartment. The assembly further includes a resilient body positioned in the interior compartment of the housing, the resilient body having a base portion and a continuous side portion extending from the base portion to define an interior channel. A display is positioned in the interior channel of the resilient body and the display and the resilient body are then positioned in the interior compartment of the housing. A sealing gasket is positioned between the top surface of the display and the cover plate, the sealing gasket overlapping a portion of the surface of the display. When the cover plate is coupled to the housing, the sealing gasket creates a tight seal between the display and the sealing gasket to inhibit the penetration of foreign matter into the interior compartment of the housing and the expansion gap in the cover plate accommodates the expansion of the sealing gasket.

Claims

1. A display assembly for a portable module, the display assembly comprising:

a housing comprising a base portion and a continuous side portion extending from the base portion to define an interior compartment;

a resilient body positioned in the interior compartment of the housing, the resilient body comprising a base portion and a continuous side portion extending from the base portion;

a display having side and bottom surfaces engaged by the resilient body;

a cover plate for enclosing the housing, the cover plate having an expansion gap; and

a sealing gasket positioned between only a top surface of the display and the cover plate, the sealing gasket overlapping a portion of the top surface of the display, the sealing gasket being a separate piece from the resilient body;

wherein when the cover plate is coupled to the housing, the sealing gasket creates a tight seal between the display and the sealing gasket to inhibit the penetration of foreign matter into the interior compartment of the housing and the expansion gap in the cover plate accommodates the expansion of the sealing gasket.

2. A display assembly according to claim 1, wherein the sealing gasket is formed from a sealing foam.

3. A display assembly according to claim 2, the cover plate further comprising a channel to accommodate the sealing foam, the channel having dimensions sufficient to encapsulate the sealing foam.

4. A display assembly according to claim 1, further comprising a touchscreen having a touchscreen layer positioned between the display and the sealing gasket.

5. A display assembly according to claim 4, wherein the touchscreen is adhered to the top surface of the display by an adhesive layer.

6. A display assembly according to claim 4, wherein the touchscreen and the display are separated by a metal spacer and a foam spacer, the touchscreen adhered to the metal spacer by an adhesive layer.

7. A display assembly according to claim 4, wherein the touchscreen layer is an indium tin oxide (ITO) layer.

8. A display assembly according to claim 1, the resilient body further comprising a ledge portion extending from the continuous side portion, the ledge portion for protecting an integrated circuit portion of the display.

9. A display assembly according to claim 1, further comprising a display transition board coupled to the display.

10. A display assembly according to claim 1, further comprising a plane grounding spring coupled to the display.

11. A display assembly according to claim 1, wherein the resilient body is formed from silicon rubber.

12. A display assembly according to claim 1, wherein the resilient body is compression molded.

13. A display assembly according to claim 4, wherein the resilient body does not engage the touchscreen.
