Abstract

A method of manufacturing a display device includes preparing a display panel that has a display region where an image is displayed and a non-display region adjacent to the display region, and disposing a power supply flexible printed circuit board (FPCB) in a lower surface of the display panel and in the non-display region of an upper surface of the display panel. The method includes disposing a tape on the display panel to cover an upper side of the power supply FPCB disposed on the upper surface of the display panel, and attaching the tape to the display panel by performing a thermal hardening process on the tape to fix the power supply FPCB to the display panel.

First claim

What is claimed is:

1. A method of manufacturing a display device, the method comprising:
preparing a display panel having an upper surface including a display region where an image is displayed and a non-display region adjacent to the display region;
disposing a power supply flexible printed circuit board (FPCB) on a lower surface of the display panel and in the non-display region of the upper surface of the display panel;
disposing a tape on the display panel to cover an upper side of the power supply FPCB disposed on the upper surface of the display panel;
disposing a printed circuit board (PCB) on the lower surface of the display panel to control driving of the display panel; and
attaching the tape to the display panel by performing a thermal hardening process on the tape to fix the power supply FPCB to the display panel.

2. The method of claim 1 , wherein the thermal hardening process is performed by applying heat to the tape for three to five seconds.

3. The method of claim 1 , wherein the thermal hardening process is performed using a laser.

4. The method of claim 1 , wherein the tape includes an ultraviolet ray curable material.

5. The method of claim 1 , wherein the tape is disposed in the non-display region of the display panel and is adjacent to a long side of the display panel.

6. The method of claim 1 , wherein the power supply FPCB has a branched structure and includes two lateral ends in the non-display region of the upper surface of the display panel, and the tape is coupled to the two lateral ends.

7. The method of claim 1 , wherein the tape is a dampproof tape.

8. The method of claim 1 , wherein the tape is formed to have a thickness of about 0.05 mm.

9. A display device, comprising:
a display panel having an upper surface including a display region where an image is displayed and a non-display region adjacent to the display region;
a power supply flexible printed circuit board (FPCB) on a lower surface of the display panel and in the non-display region of the upper surface of the display panel;
a driving printed circuit board (PCB) electrically connected to the power supply FPCB through a connector; and
a tape attached to the non-display region of the display panel to cover an upper side of the power supply FPCB on the upper surface of the display panel.

10. The display device of claim 9 , wherein the tape includes an ultraviolet ray curable material.

11. The display device of claim 9 , wherein the tape is arranged in the non-display region of the display panel and is adjacent to a long side of the display panel.

12. The display device of claim 9 , wherein the power supply FPCB has a branched structure and includes two lateral ends in the non-display region of the upper surface of the display panel, and the tape is coupled to the two lateral ends.

13. The display device of claim 9 , wherein the tape is a dampproof tape.

14. The display device of claim 9 , wherein the tape has a thickness of about 0.05 mm.

15. The display device of claim 9 , wherein the power supply FPCB is formed in an integrated form on the lower surface and the upper surface of the display panel.

16. The display device of claim 9 , wherein the driving PCB is disposed on the lower surface of the display panel.

17. The display device of claim 9 , wherein an end of the power supply FPCB is electrically connected to the driving PCB.

18. The display device of claim 16 , wherein the driving PCB is disposed in a lower part of the lower surface of the display panel.

19. A display device, comprising:
a display panel including a display region where an image is displayed and a non-display region adjacent to the display region;
a power supply flexible printed circuit board (FPCB) on a lower surface of the display panel and in the non-display region of an upper surface of the display panel;
a tape attached to the non-display region of the display panel to cover an upper side of the power supply FPCB on the upper surface of the display panel; and
a driving printed circuit board (PCB) configured to control driving of the display panel,
wherein an end of the power supply FPCB is electrically connected to the driving PCB, and the power supply FPCB and the driving PCB are electrically connected through a connector.
