Abstract

An electronic device is provided. The electronic device includes a front glass cover forming a front face of the electronic device, a rear glass cover forming a rear face of the electronic device, a metal bezel encapsulating a space formed by the front glass cover and the rear glass cover, and a display device disposed in the space and that includes a screen region exposed through the front glass cover. At least one glass cover of the front glass cover and the rear glass cover includes a surface that includes a first edge, a second edge extending at an opposite side to the first edge, a third edge interconnecting a first end of the first edge and a first end of the second edge, and a fourth edge interconnecting a second end of the first edge and a second end of the second edge.

First claim

What is claimed is:

1. A portable electronic device comprising:
a front glass cover forming a front face of the electronic device;
a rear glass cover forming a rear face of the electronic device;
a metal bezel encapsulating a space formed by the front glass cover and the rear glass cover; and
a display device disposed in the space and that includes a screen region exposed through the front glass cover,
wherein at least one glass cover of the front glass cover and the rear glass cover includes a surface comprising:
a first edge;
a second edge extending at an opposite side to the first edge;
a third edge interconnecting a first end of the first edge and a first end of the second edge; and
a fourth edge interconnecting a second end of the first edge and a second end of the second edge, and

wherein when viewed from a cross-section, the at least one glass cover includes:
a first region having a thickness that decreases at a first gradient toward the first edge, and positioned adjacent to the first edge;
a second region having a thickness that decreases at the first gradient toward the second edge, and positioned adjacent to the second edge;
a third region having a thickness that decreases at a second gradient, which is different from the first gradient, toward the third edge, and positioned adjacent to the third edge; and
a fourth region having a thickness that decreases at the second gradient toward the fourth edge, and positioned adjacent to the fourth edge.

2. The portable electronic device of claim 1 , wherein at least one of the first to fourth regions includes a curved face.

3. The portable electronic device of claim 1 , wherein the at least one glass cover includes an external face exposed to an outside and an internal face facing to an inside of the electronic device, and the internal face is a substantially flat face.

4. The portable electronic device of claim 1 , wherein the first region and the second region are symmetrical to each other, and the third region and the fourth region are symmetrical to each other.

5. The portable electronic device of claim 1 , wherein the screen region has a rectangular shape having a first short side adjacent to the first edge, a second short side adjacent to the second edge, a first long side adjacent to the third edge, and a second long side adjacent to the fourth edge.

6. The portable electronic device of claim 5 , wherein the second gradient is smaller than the first gradient.

7. The portable electronic device of claim 1 ,
wherein the at least one glass cover is the rear glass cover,
wherein the metal bezel comprises:
a first corner portion adjacent to a location where the first edge and the third edge are connected to each other;
a second corner portion adjacent to a location where the first edge and the fourth edge are connected to each other; and
a first connecting portion between the first corner portion and the second corner portion, and

wherein, in a direction from the front face to the rear face of the electronic device when viewed from the cross-section, the first corner portion and the second corner portion have a first thickness, and the first connecting portion has a second thickness that is smaller than the first thickness.

8. The portable electronic device of claim 7 ,
wherein the metal bezel comprises:
a third corner portion adjacent to a location where the second edge and the third edge are connected to each other;
a fourth corner portion adjacent to a location where the second edge and the fourth edge are connected to each other; and
a second connecting portion between the third corner portion and the fourth corner portion, and

wherein, in the direction from the front face to the rear face of the electronic device when viewed from the cross section, the third corner portion and the fourth corner portion have the first thickness, and the second connecting portion has the second thickness.

9. The portable electronic device of claim 8 ,
wherein the metal bezel comprises:
a third connecting portion between the first corner portion and the third corner portion; and
a fourth connecting portion between the second corner portion and the fourth corner portion,

wherein, in the direction from the front face to the rear face of the electronic device when viewed from the cross-section, the third connecting portion and the fourth connecting portion have a third thickness that is smaller than the first thickness.

10. The portable electronic device of claim 9 ,
wherein the rear glass cover includes a central region that is surrounded by the first to fourth regions,
wherein the first corner portion includes a first corner face that forms a surface parallel to the rear face,
wherein the second corner portion includes a second corner face that forms a surface parallel to the rear face,
wherein the first connecting portion includes a first connecting face that forms a surface parallel to the rear face, and
wherein the first corner face and the second corner face protrude more than the central region in the direction from the front face to the rear face of the electronic device when viewed from the cross-section.

11. The portable electronic device of claim 10 , wherein the first connecting face protrudes less than the central region in the direction from the front face to the rear face of the electronic device when viewed from the cross-section.

12. The portable electronic device of claim 10 ,
wherein the third connecting portion includes a third connecting face that forms a surface parallel to the rear face, and
wherein the third connecting face protrudes less than the central region and the third region in the direction from the front face to the rear face of the electronic device when viewed from the cross-section.

13. The portable electronic device of claim 1 , wherein the at least one glass cover is the front glass cover, and the first region and the second region do not overlap with the screen region.

14. The portable electronic device of claim 1 ,
wherein the at least one glass cover is the front glass cover,
wherein the metal bezel comprises:
a first corner portion adjacent to a location where the first edge and the third edge are connected to each other;
a second corner portion adjacent to a location where the first edge and the fourth edge are connected to each other; and
a first connecting portion between the first corner portion and the second corner portion, and

wherein, in a direction from the rear face to the front face of the electronic device when viewed from the cross-section, the first corner portion and the second corner portion have a first thickness, and the first connecting portion has a second thickness that is smaller than the first thickness.

15. The portable electronic device of claim 14 ,
wherein the metal bezel comprises:
a third corner portion adjacent to a location where the second edge and the third edge are connected to each other;
a fourth corner portion adjacent to a location where the second edge and the fourth edge; and
