Abstract

A curved display including an external protective layer with an edge at least a part of which has a certain curvature, an opaque layer disposed at the edge of the external protective layer, and a panel module layer including an electrode trace area aligned under the opaque layer.

First claim

What is claimed is:

1. A mobile electronic device comprising:
a display comprising:
a flat area; and
a curved surface area extending from the flat area as one piece therewith, the curved surface area being bent towards one side of the flat area, the curved surface area having a size smaller than a size of the flat area; and

a case disposed along an edge of the display, at least a part of the case protruding over a surface of the curved surface area,
wherein the display comprises:
an external protective layer formed in a shape corresponding to the flat area and the curved surface area;
an opaque area disposed at a part of an edge of the curved surface area under the external protective layer; and
a panel module disposed under the external protective layer, the panel module comprising a display area and a non-display area, the display area being disposed over the flat area and a first part of the curved surface area, the non-display area being disposed at a second part of the curved surface area other than the first part of the curved surface area,
wherein the opaque layer covers an entirety of the non-display area with respect to a vertical direction to the flat area at the edge of the curved surface area, and wherein the case comprises: a battery placing part biased in a direction away from the second part of the curved surface area with respect to a vertical center line of the mobile electronic device; a rail groove formed in a longitudinal direction in a surface of the case facing a back of an edge side of the display; a protective member inserted into the rail groove.

2. The mobile electronic device according to claim 1 , wherein at least a part of an end of the curved surface area of the external protective layer and at least a part of an end of the panel module are arranged in parallel with each other in the display.

3. The mobile electronic device according to claim 1 , wherein the case further comprises:
a support groove configured to receive insertion of the non-display area; and
a sidewall constituting a part of the support groove, the sidewall facing a side surface of an edge of the external protective layer.

4. The mobile electronic device according to claim 1 , wherein the display further comprises at least one of:
an electromagnetic induction panel disposed on the curved surface area, the electromagnetic induction panel having a certain curvature;
a heat-dissipating sheet disposed on the curved surface area, the heat-dissipating sheet having a certain curvature; and
a touch sensing layer interposed between the external protective layer and the panel module, the touch sensing layer being bent at the curved surface area.

5. The mobile electronic device according to claim 1 , wherein the curved surface area is convex with respect to the flat area.

6. The mobile electronic device according to claim 1 , wherein the case further comprises:
an auxiliary groove formed in at least a part of a surface of the case exposed to an outside of the mobile electronic device; and
a reinforcing member disposed in the auxiliary groove configured to absorb or disperse a shock.

7. The mobile electronic device according to claim 1 , wherein the case comprises a shock absorbing member disposed on one surface of a curved surface cover part facing an end of the edge of the display.

8. The mobile electronic device according to claim 1 , further comprising:
an adhesive member disposed under the flat area of the display, the adhesive member being selectively disposed under at least a part of the curved surface area of the display.

9. The mobile electronic device according to claim 1 , wherein the curved surface area is formed on edges of both sides of the display.

10. A mobile electronic device comprising: a display comprising: a flat area; and a curved surface area extending from the flat area as one piece therewith, the curved surface area being bent towards one side of the flat area, the curved surface area having a size smaller than a size of the flat area; and a case disposed along an edge of the display, at least a part of the case protruding over a surface of the curved surface area, wherein the display comprises: an external protective layer formed in a shape corresponding to the flat area and the curved surface area; and a panel module disposed under the external protective layer, the panel module comprising a display area and a non-display area, the display area being disposed over the flat area and a first part of the curved surface area, the non-display area being disposed at a second part of the curved surface area other than the first part of the curved surface area, wherein the case comprises: a rail groove formed in a longitudinal direction in a surface of the case facing a back of an edge side of the display; a protective member inserted into the rail groove; and a battery placing part biased towards the first part of the curved surface area having a curvature different from a curvature of the second part of the curved surface area or towards an edge of the flat area not adjacent to the second part of the curved surface area, with respect to a vertical center line of the mobile electronic device, and wherein an end of the panel module comprising at least a part of the non-display area extends further than an end of the curved surface area of the external protective layer and configured to be inserted into a support groove formed in one side of the case.

11. The mobile electronic device according to claim 10 , wherein the display further comprises at least one of:
an electromagnetic induction panel disposed on the curved surface area, the electromagnetic induction panel having a certain curvature;
a heat-dissipating sheet disposed on the curved surface area, the heat-dissipating sheet having a certain curvature; and
a touch sensing layer interposed between the external protective layer and the panel module, the touch sensing layer being bent at the curved surface area.

12. The mobile electronic device according to claim 10 , further comprising:
an adhesive member disposed on at least a part of an area under the flat area of the display, the adhesive member being selectively disposed under at least a part of the curved surface area of the display.

13. The mobile electronic device according to claim 10 , wherein the case further comprises at least one of: a reinforcing member disposed on at least a part of a surface of the case exposed to an outside of the mobile electronic device configured to absorb or disperse a shock; and a shock absorbing member disposed on one surface of a curved surface cover part facing an end of the edge of the display.

14. The mobile electronic device of claim 1 , wherein the protective member comprises at least one of a sponge and an adhesive tape.

15. The mobile electronic device of claim 10 , wherein the protective member comprises at least one of a sponge and an adhesive tape.
