Abstract

A display device, including a display panel; a flexible printed circuit board (FPCB) including a driving integrated circuit (IC) and attached to a rear surface of the display panel; a conductive member at the rear surface of the display panel; an FPCB connection pad connected to the conductive member at the rear surface of the display panel and connected to the FPCB; an FPCB connection terminal connected to the FPCB connection pad and at the FPCB; and a ground at the FPCB.

Claims (24)

1. A display device, comprising:

a display panel;

a flexible printed circuit board (FPCB) including a driving integrated circuit (IC) and attached to a rear surface of the display panel;

a conductive member at the rear surface of the display panel, the conductive member absorbing and transmitting static electricity generated in the display panel;

an FPCB connection pad connected to the conductive member at the rear surface of the display panel and connected to the FPCB; and

an FPCB connection terminal connected to the FPCB connection pad and at the FPCB, the FPCB connection terminal transmitting transmitted static electricity to a ground at the FPCB.

2. The display device as claimed in claim 1 , wherein the conductive member is at a circumferential edge of the display panel.

3. The display device as claimed in claim 1 , wherein the conductive member is a loop shape that is symmetrically divided into two portions.

4. The display device as claimed in claim 1 , wherein the conductive member includes a plurality of disconnected sections.

5. The display device as claimed in claim 4 , wherein the sections are separated by about 50 micrometers (μm) to 100 micrometers (μm).

6. The display device as claimed in claim 1 , wherein the conductive member is on a functional tape attached to the rear surface of the display panel.

7. The display device as claimed in claim 6 , wherein the functional tape includes:

an embossed tape attached to the rear surface of the display panel;

an adhesion sheet on the embossed tape; and

a protection tape on the adhesion sheet.

8. The display device as claimed in claim 7 , wherein the conductive member is formed on a same layer and as one body with the protection tape.

9. The display device as claimed in claim 6 , wherein the conductive member has parallel portions protruding from the functional tape with a gap therebetween.

10. The display device as claimed in claim 1 , wherein the conductive member includes a metal material.

11. The display device as claimed in claim 10 , wherein the metal material includes stainless steel (SUS), copper (Cu), or silver (Ag).

12. The display device as claimed in claim 1 , comprising more than one FPCB connection pad.

13. The display device as claimed in claim 1 , wherein the display panel is flexible.

14. The display device as claimed in claim 1 , wherein:

the FPCB is bent toward the display panel; and

the FPCB connection terminal overlaps the FPCB connection pad.
