Abstract

A method of bending a flexible display panel including a flexible substrate extending from a display area to a non-display area and a support layer disposed on the flexible substrate in the display area and the non-display area, the method including altering, via thermal deformation, a property of a material of the support layer disposed on the flexible substrate in the non-display area of the flexible display panel; and bending, after altering the property, a portion of the support layer in non-display area that extends from a plane of the support layer in the display area of the flexible display panel.

Claims (18)

1. A method of bending a flexible display panel including a flexible substrate extending from a display area to a non-display area and a support layer disposed on the flexible substrate in the display area and the non-display area, the method comprising:

altering, via thermal deformation, a property of a material of the support layer disposed on the flexible substrate in the non-display area of the flexible display panel; and

bending, after altering the property, a portion of the support layer in non-display area that extends from a plane of the support layer in the display area of the flexible display panel.

2. The method of claim 1 , wherein the property corresponds to at least one of a density of the material, a hardness of the material, a surface roughness of the material, and a color of the material.

3. The method of claim 1 , wherein the thermal deformation includes melting portions of the material of the support layer in the non-display area.

4. The method of claim 3 , further comprising:

disposing a wire on the support layer in the non-display area,

wherein the disposing of the wire causes, at least in part, the melting of the portions of the material of the support layer in the non-display area.

5. The method of claim 1 , wherein the thermal deformation corresponds to a sublimation of some of the material of the support layer in the non-display area.

6. The method of claim 5 , further comprising:

disposing a stamp on the support layer in the non-display area,

wherein the disposing of the stamp causes, at least in part, some of the material of the support layer to sublimate in the non-display area.

7. The method of claim 1 , further comprising:

removing, via a rotational cutting tool, a first portion of the support layer disposed in the portion of the non-display area,

wherein rotation of the rotational cutting tool causes, at least in part, the thermal deformation in a second portion of the support layer.

8. The method of claim 7 , wherein:

bending the portion of the non-display area causes opposing surfaces of the non-display area to contact one another, at least one of the opposing surfaces being associated with the second portion of the support layer; and

the opposing surfaces are coupled to one another via cooling of the second portion.
