Electronic device structure with housing
An electronic device can include a housing defining an aperture and a display assembly at least partially positioned in the aperture. The display assembly can include a substrate having a conductive portion, a display layer having pixels, a touch sensitive layer positioned on a first side of the substrate, an operational component positioned on a second side of the substrate opposite the first side, and a flexible electrical connector electrically coupled with the conductive portion and the operational component. The flexible electrical connector can include an electromagnetic antenna. A transparent cover can overlay the display assembly and can be secured to the housing.
1. A housing assembly of an electronic device, comprising:
a housing component at least partially defining a first exterior surface and an internal volume of the electronic device, the housing component further defining:
an aperture;
a first planar surface at least partially surrounding a periphery of the aperture; and
a housing sidewall adjacent to at least a portion of a periphery of the first planar surface opposite the aperture;
a sealing component defining a rectangular cross-sectional area, the sealing component adhered to the first planar surface and surrounding the aperture; and
an optically transparent cover overlying the aperture and defining:
a second exterior surface forming a back side of the housing assembly opposite a display assembly;
an electromagnetically transparent cover at least partially occluding the aperture and defining a third exterior surface, the electromagnetically transparent cover secured to the second exterior surface;
a second planar surface adhered on the sealing component opposite the first planar surface; and
a cover sidewall oriented perpendicular to the first planar surface and spaced apart from the housing sidewall by a distance;
wherein the housing component defines a planar datum surface offset from and parallel to the first planar surface, the planar datum surface contacting the second planar surface.
2. The housing assembly of claim 1 , wherein the sealing component comprises a first adhesive layer adhered to the first planar surface, a second adhesive layer adhered to the second planar surface, and a compliant layer disposed between the first adhesive layer and the second adhesive layer.
3. The housing assembly of claim 2 , wherein the compliant layer comprises silicone rubber.
4. The housing assembly of claim 2 , further comprising:
a first polymer layer disposed between the compliant layer and the first adhesive layer; and
a second polymer layer disposed between the compliant layer and the second adhesive layer.
5. The housing assembly of claim 2 , wherein the compliant layer has a Shore A hardness of between 5 and 15.
6. The housing assembly of claim 1 , wherein the sealing component has a thickness of between 200 microns and 600 microns.
7. The housing assembly of claim 2 , wherein the compliant layer has a thickness of between 50 microns and 500 microns.
8. The housing assembly of claim 1 , wherein the sealing component prevents ingress of liquids into the internal volume at locations between the housing component and the transparent cover.
