Abstract

An electronic device may have a glass housing structures. The glass housing structures may be used to cover a display and other internal electronic device components. The glass housing structure may have multiple glass pieces that are joined using a glass fusing process. A peripheral glass member may be fused along the edge of a planar glass member to enhance the thickness of the edge. A rounded edge feature may be formed by machining the thickened edge. Raised fused glass features may surround openings in the planar glass member. Multiple planar glass members may be fused together to form a five-sided box in which electronic components may be mounted. Raised support structure ribs may be formed by fusing glass structures to a planar glass member. Opaque masking material and colored glass may be used to create portions of the glass housing structures that hide internal device components from view.

Claims

1. An electronic device, comprising:

a display; and

a housing in which the display is mounted, wherein the housing includes glass structures that have a recess that receives at least part of the display, wherein the glass structures include a planar glass member and a peripheral glass member that extends around at least some peripheral edge portions of the planar glass member to form the recess,

wherein the planar glass member has a thickness of T1 and the glass structures at the at least some peripheral edge portions have a thickness of T2, and wherein the thickness of T1 is less than the thickness of T2.

2. The electronic device defined in claim 1 wherein the peripheral glass member comprises non-clear glass.

3. The electronic device defined in claim 1 wherein the planar glass member is characterized by a surface normal and wherein the peripheral glass member has an inner edge that is angled at a non-zero angle with respect to the surface normal.

4. The electronic device defined in claim 1 wherein the peripheral glass member has an inner edge with a curved surface.

5. The electronic device defined in claim 1 wherein the peripheral glass member has an inner edge, the electronic device further comprising an opaque masking material that coats at least some of the inner edge.

6. The electronic device defined in claim 1 wherein the planar glass member and peripheral glass member have curved portions that form a rounded edge for the housing.

7. The electronic device defined in claim 1 wherein the housing comprises a housing structure to which the glass structures are mounted, the electronic device further comprising internal electrical components mounted between the housing structure and the glass structures.

8. The electronic device defined in claim 7 wherein the housing structure comprises a metal structure.

9. The electronic device defined in claim 7 wherein housing structure comprises glass.

10. The electronic device defined in claim 1 wherein the planar glass member is fused with the peripheral glass member.

11. The electronic device defined in claim 10 wherein the housing comprises a housing structure to which the glass structures are mounted, the electronic device further comprising internal electrical components mounted between the housing structure and the glass structures.

12. The electronic device defined in claim 11 wherein the peripheral glass member has an inner edge, the electronic device further comprising an opaque masking material that coats at least some of the inner edge.

13. The electronic device defined in claim 12 wherein the planar glass member and peripheral glass member have curved portions that form a rounded edge for the housing.

14. The electronic device defined in claim 11 wherein the peripheral glass member comprises non-clear glass.

15. The electronic device defined in claim 14 wherein the planar glass member and peripheral glass member have curved portions that form a rounded edge for the housing.

16. An electronic device, comprising:

an electronic device housing formed from glass members including at least first and second opposing planar glass members that are separated by a gap formed between the first and second opposing planar glass members; and

display structures inserted into the gap.

17. The electronic device defined in claim 16 wherein the electronic device housing includes a clear portion through which the display is visible.

18. The electronic device defined in claim 17 further comprising opposing third and fourth planar glass members that are separated by another gap.

19. The electronic device defined in claim 16 further comprising fused glass rib support structures on the first planar glass member.

20. The electronic device defined in claim 16 wherein the electronic device housing includes a clear portion through which the display is visible.
