Abstract

An electronic device including a housing defining an aperture, a display component positioned in the aperture, and a filler material at least partially surrounding a periphery of the display component. The filler material can contact the display component and a portion of the housing defining the aperture.

First claim

What is claimed is:

1. An electronic device comprising:
a frame defining an aperture;
a display component positioned in the aperture and configured to present visual information, the display component defining a bend region;
a filler material at least partially surrounding a periphery of the display component, the filler material contacting the bend region and contacting a portion of the frame defining the aperture.

2. The electronic device of claim 1 , wherein the filler material comprises epoxy.

3. The electronic device of claim 1 , further comprising a housing at least partially defining an internal volume, wherein the frame is secured to the housing and the filler material defines a seal between an ambient environment and the internal volume.

4. The electronic device of claim 1 , further comprising a housing at least partially defining an internal volume, wherein the frame is secured to the housing and the filler material defines a tortuous leak path between an ambient environment and the internal volume.

5. The electronic device of claim 1 , further comprising a parylene coating covering at least one of the display component or the filler material.

6. The electronic device of claim 1 , further comprising a housing at least partially surrounding and secured to the frame.

7. The electronic device of claim 1 , wherein the frame defines ports for injecting the filler material between the frame and the display component.

8. The electronic device of claim 1 , wherein the filler material is curable.

9. The electronic device of claim 1 , wherein the bend region defines a curved surface; and
the filler material comprises a potting material that is positioned in the bend region and in contact with the curved surface.

10. The electronic device of claim 1 , wherein the filler material has a modulus of about 10 megapascals to about 20 megapascals.

11. A display assembly, comprising;
a frame comprising sidewalls that define ports and an aperture;
a display component defining a bend region, the display component configured to display information and positioned in the aperture, the display component and the frame at least partially defining a volume;
a flowable filler material at least partially surrounding a periphery of the display component and positioned in the volume, the filler material contacting the bend region and contacting one of the sidewalls.

12. The display assembly of claim 11 , wherein the filler material has a non-uniform thickness.

13. The display assembly of claim 11 , wherein the filler material adheres to the frame.

14. The display assembly of claim 11 , wherein the filler material occupies substantially all of the volume.

15. The display assembly of claim 11 , wherein the filler material is non-reactive to moisture.
