Abstract

An apparatus for attaching a display panel includes a panel mount which receives a panel bottom cover facing corner portions of the display panel which are extended bent from a front surface of the display panel, and a pressing module which provides a pressing force to the panel bottom cover which is received in the panel mount and faces the corner portions of the display panel. The pressing module includes a pressing pad which applies the pressing force to the panel bottom cover at the corner portions of the display panel to attach the panel bottom cover to the display panel at the corner portions thereof.

First claim

What is claimed is:

1. A method of providing an electronic device, the method comprising:
providing a display panel of the electronic device on a panel mount, the display panel comprising:
a front surface,
a first side surface extending bent from a first side of the front surface,
a second side surface extending bent from a second side of the front surface,
a third side surface extending bent from a third side of the front surface which faces the first side,
a fourth side surface extending bent from a fourth side of the front surface which faces the second side,
a first corner which connects the first side surface to the second side surface,
a second corner which connects the second side surface to the third side surface,
a third corner which connects the third side surface to the fourth side surface, and
a fourth corner which connects the fourth side surface to the first side surface;

providing a panel bottom cover of the electronic device on the panel mount and facing the display panel; and
providing a pressing force to the panel bottom cover using a pressing pad at the first corner, the second corner, the third corner and the fourth corner of the display panel to respectively attach the panel bottom cover to the display panel at the first corner, the second corner, the third corner and the fourth corner thereof,
wherein the pressing pad comprises:
a first pressing portion, a second pressing portion, a third pressing portion and a fourth pressing portion respectively corresponding to the first side surface, the second side surface, the third side surface and the fourth side surface of the display panel;
a first corner-pressing portion corresponding to the first corner portion of the display panel, and disposed between the first pressing portion and the second pressing portion;
a second corner-pressing portion corresponding to the second corner portion of the display panel, and disposed between the second pressing portion and the third pressing portion;
a third corner-pressing portion corresponding to the third corner portion of the display panel, and disposed between the third pressing portion and the fourth pressing portion; and
a fourth corner-pressing portion corresponding to the fourth corner portion of the display panel, and disposed between the fourth pressing portion and the first pressing portion.

2. The method of claim 1 , wherein
the providing of the pressing force includes providing the pressing pad fixed to a pressing bracket at an inside thereof, and
the pressing pad which is fixed to the pressing bracket extends to outside the pressing bracket in a direction towards the panel mount.

3. The method of claim 2 , further comprising:
providing the pressing force to the panel bottom cover at the front surface, the second side surface and the fourth side surface of the display panel using a first roller; and
providing the pressing force to the panel bottom cover at the front surface, the first side surface and the third side surface of the display panel using a second roller.

4. The method of claim 3 , wherein
each of the panel bottom cover, the display panel, the first roller and the second roller has a length, and
lengths of the first roller and the second roller are different from the lengths of the panel bottom cover and the display panel.

5. The method of claim 1 , wherein
the first side surface of the display panel comprises a first curved surface extending curved from the first side of the front surface, and a first flat surface extending from an end of the first curved surface,
the second side surface of the display panel comprises a second curved surface extending curved from the second side of the front surface, and a second flat surface extending from an end of the second curved surface,
the third side surface of the display panel comprises a third curved surface extending curved from the third side of the front surface, and a third flat surface extending from an end the third curved surface, and
the fourth side surface of the display panel comprises a fourth curved surface extending curved from the fourth side of the front surface, and a fourth flat surface extending from an end the fourth curved surface.

6. The method of claim 5 , further comprising:
providing the pressing force to the panel bottom cover at the front surface of the display panel using a roller to attach the panel bottom cover to the display panel at the front surface thereof;
providing the pressing force to the panel bottom cover at the first flat surface and the third flat surface of the display panel using a first side-pressing pad to attach the panel bottom cover to the display panel at the first flat surface and the third flat surface thereof; and
providing the pressing force to the panel bottom cover at the second flat surface and the fourth flat surface of the display panel using a second side-pressing pad to attach the panel bottom cover to the display panel at the second flat surface and the fourth flat surface thereof.

7. The method of claim 6 , wherein the providing the pressing force to the panel bottom cover using the pressing pad at the first corner, the second corner, the third corner and the fourth corner of the display panel further attaches the panel bottom cover to the first curved surface, the second curved surface, the third curved surface and the fourth curved surface of the display panel.

8. A method of providing an electronic device, the method comprising:
providing a display panel of the electronic device on a panel mount, the display panel comprising:
a front surface,
a first side surface extending bent from a first side of the front surface,
a second side surface extending bent from a second side of the front surface,
a third side surface extending bent from a third side of the front surface which faces the first side,
a fourth side surface extending bent from a fourth side of the front surface which faces the second side,
a first corner which connects the first side surface to the second side surface,
a second corner which connects the second side surface to the third side surface,
a third corner which connects the third side surface to the fourth side surface, and
a fourth corner which connects the fourth side surface to the first side surface;

providing a panel bottom cover of the electronic device on the panel mount and facing the display panel;
providing the panel bottom cover preliminarily attached to the display panel by providing a pressing force to the panel bottom cover at the front surface, the second side surface and the fourth side surface of the display panel using a first roller rolled along the front surface and between the fourth side surface and the second side surface; and
after the providing the panel bottom cover preliminarily attached to the display panel, providing the pressing force to the panel bottom cover using a pressing pad at the first corner, the second corner, the third corner and the fourth corner of the display panel to respectively attach the panel bottom cover to the display panel at the first corner, the second corner, the third corner and the fourth corner thereof.

9. The method of claim 8 , the providing the panel bottom cover preliminarily attached to the display panel further comprising, providing the pressing force to the panel bottom cover at the front surface, the first side surface and the third side surface of the display panel using a second roller rolled along the front surface and between the first side surface to the third side surface.

10. The method of claim 9 , wherein the pressing pad comprises:
a first pressing portion, a second pressing portion, a third pressing portion and a fourth p
