Abstract

A display device manufacturing apparatus includes a support portion including a core portion and a conductive portion disposed over the core portion. The core portion includes a first flat surface extending in a first direction; a second flat surface extending in the first direction and being opposite to the first flat surface; and a curved surface extending between the first flat surface and the second flat surface. The conductive portion includes a first flat conductive portion overlapping the first flat surface of the core portion in a second direction; a second flat conductive portion overlapping the second flat surface of the core portion in the second direction; and a curved conductive portion extending between the first flat conductive portion and the second flat conductive portion.

Claims (38)

1. A display device manufacturing apparatus comprising:

a support portion including a core portion and an electrically conductive portion disposed over the core portion; and

a magnetic portion that partially surrounds the support portion, the magnetic portion capable of conducting an electric current, wherein

the core portion includes:

a first flat surface extending in a first direction;

a second flat surface extending in the first direction and being opposite to the first flat surface; and

a curved surface extending between the first flat surface and the second flat surface,

the conductive portion includes:

a first flat conductive portion overlapping the first flat surface of the core portion in a second direction;

a second flat conductive portion overlapping the second flat surface of the core portion in the second direction; and

a curved conductive portion extending between the first flat conductive portion and the second flat conductive portion, and

in response to an electric current flowing in the magnetic portion, an electrostatic attractive force is formed between the magnetic portin and the conductive portion, causing at least one part of the magnetic portion to move towards an overlapping part of the conductive portion.

2. The display device manufacturing apparatus of claim 1 , further comprising a magnetic portion disposed over the support portion, wherein the magnetic portion includes:

a first flat magnetic portion overlapping the first flat conductive portion in the second direction;

a second flat magnetic portion overlapping the second flat conductive portion in the second direction; and

a curved magnetic portion extending between the first flat magnetic portion and the second flat magnetic portion.

3. The display device manufacturing apparatus of claim 2 , wherein moving the magnetic portion to move towards the overlapping part of the conductive portion enables the display device manufacturing apparatus to attach a window having a curved portion to a display panel having a curved portion.

4. The display device manufacturing apparatus of claim 3 , wherein the core portion is in direct contact with the conductive portion.

5. The display device manufacturing apparatus of claim 4 , wherein the support portion includes a pad portion disposed over the conductive portion, wherein the pad portion includes:

a first flat pad portion overlapping the first flat conductive portion in the second direction;

a second flat pad portion overlapping the second flat conductive portion in the second direction; and

a curved pad portion extending between the first flat pad portion and the second flat pad portion.

6. The display device manufacturing apparatus of claim 5 , wherein the pad portion is in direct contact with the conductive portion.

7. The display device manufacturing apparatus of claim 5 , further comprising a guide film portion disposed over the support portion, wherein the guide film portion includes:

a first flat film portion overlapping the first flat conductive portion in the second direction;

a second flat film portion overlapping the second flat conductive portion in the second direction; and

a curved film portion extending between the first flat film portion and the second flat film portion.

8. The display device manufacturing apparatus of claim 7 , wherein the guide film portion is in direct contact with the support portion.

9. The display device manufacturing apparatus of claim 8 , wherein

the first flat magnetic portion includes:

an end in contact with the curved magnetic portion; and

another end opposite to the end,

the first flat film portion and the second flat film portion extend in the first direction from the another end of the first flat magnetic portion, and

roller portions are disposed on extended portions of the first flat film portion and the second flat film portion along the first direction from the another end of the first flat magnetic portion.

10. The display device manufacturing apparatus of claim 9 , wherein the extended portions of the first flat film portion and the second flat film portion are fixed by the roller portions.

11. The display device manufacturing apparatus of claim 1 , wherein in response to an electric current flowing in the magnetic portion, the magnetic portion moves at outside of the support portion in a direction from the curved conductive portion to the first flat conductive portion, or from the curved conductive portion to the second flat conductive portion.

12. The display device manufacturing apparatus of claim 11 , wherein moving the magnetic portion enables the display device manufacturing apparatus to attach a window having a curved portion to a display panel having a curved portion.

13. The display device manufacturing apparatus of claim 1 , wherein the magnetic portion includes a plurality of sub-magnetic portions capable of being individually operated such that the sub-magnetic portions are capable of being sequentially operated or simultaneously operated.
