Abstract

A flexible display device includes a flexible display module including a flexible display panel; a first frame and a second frame supporting the flexible display module; and a fixing coupler and an aligning coupler coupling the flexible display module with the first frame and the second frame, and the fixing coupler includes: a first fixing coupler fixing at least a portion of the first frame and at least a portion of the flexible display module; and a second fixing coupler fixing at least a portion of the second frame and at least a portion of the flexible display module, and the aligning coupler includes: a first aligning coupler fixed to another portion of the flexible display module; and a second aligning coupler fixed to another portion of the first frame and detachably coupled to the first aligning coupler.

Claims (45)

1. A flexible display device comprising:

a flexible display module comprising a flexible display panel;

a first frame and a second frame supporting the flexible display module, the first and second frames being rotatable relative to each other between an unfolded state in which the flexible display module is flat and a folded state in which the flexible display module is folded; and

a first coupler and a second coupler coupling the flexible display module with the first frame and the second frame,

wherein the first coupler comprises: a third coupler fixing at least a portion of the first frame and at least a portion of the flexible display module; and a fourth coupler fixing at least a portion of the second frame and at least a portion of the flexible display module, and

the second coupler comprises:

a fifth coupler fixed to the flexible display module,

a sixth coupler fixed on the first frame and detachably coupled to the fifth coupler, and

a seventh coupler fixed on the second frame and detachably coupled to the fifth coupler,

wherein the sixth and seventh couplers are coupled to the fifth coupler when the first and second frames are in the unfolded state.

2. The flexible display device as claimed in claim 1 , wherein the fifth coupler comprises a panel magnetic layer fixed to the flexible display module and having magnetic properties,

the sixth coupler comprises a first frame magnetic layer fixed on the first frame and having magnetic properties, and

the seventh coupler comprises a second frame magnetic layer fixed on the second frame and having magnetic properties.

3. A flexible display device comprising:

a flexible display module comprising a flexible display panel;

a first frame and a second frame supporting the flexible display module; and

a first coupler and a second coupler coupling the flexible display module with the first frame and the second frame,

wherein the first coupler comprises: a third coupler fixing at least a portion of the first frame and at least a portion of the flexible display module; and a fourth coupler fixing at least a portion of the second frame and at least a portion of the flexible display module, and

the second coupler comprises:

a fifth coupler fixed to the flexible display module,

a sixth coupler fixed on the first frame and detachably coupled to the fifth coupler, and

a seventh coupler fixed on the second frame and detachably coupled to the fifth coupler,

wherein the fifth coupler comprises a static electricity plate fixed to the flexible display module and having magnetic properties,

the sixth coupler comprises a first static electricity generator fixed on the first frame and detachably coupled to the static electricity plate, and

the seventh coupler comprises a second static electricity generator fixed on the second frame and detachably coupled to the static electricity plate.

4. The flexible display device as claimed in claim 1 , further comprising a third frame supporting the flexible display module;

a first hinge portion pivotally coupling the first frame and the second frame; and

a second hinge portion pivotally coupling the second frame and the third frame.

5. The flexible display device as claimed in claim 4 , wherein the first coupler further comprises an eighth coupler fixing at least a portion of the third frame and at least a portion of the flexible display module.

6. A flexible display device comprising:

a flexible display module comprising a flexible display panel;

a first frame, a second frame, and a third frame supporting the flexible display module;

a first hinge portion pivotally coupling the first frame and the second frame;

a second hinge portion pivotally coupling the second frame and the third frame; and

a first coupler and a second coupler coupling the flexible display module with the first frame and the second frame,

wherein the first coupler comprises: a third coupler fixing at least a portion of the first frame and at least a portion of the flexible display module; and a fourth coupler fixing at least a portion of the second frame and at least a portion of the flexible display module,

the second coupler comprises:

a fifth coupler fixed to the flexible display module,

a sixth coupler fixed on the first frame and detachably coupled to the fifth coupler, and

a seventh coupler fixed on the second frame and detachably coupled to the fifth coupler,

wherein the first coupler further comprises an eighth coupler fixing at least a portion of the third frame and at least a portion of the flexible display module, and

wherein the second coupler further comprises:

a ninth coupler fixed to the flexible display module;

a tenth coupler fixed on the second frame and detachably coupled to the ninth coupler; and

an eleventh coupler fixed on the third frame and detachably coupled to the ninth coupler.
