Abstract

In one embodiment, the display device includes a display panel and a support frame. The display panel includes a flexible upper substrate, at least one light emitting diode, and a flexible lower substrate ( 30 ). The display panel has a display area formed at a portion corresponding to the light emitting diode, and a non-display area formed at a portion other than the display area. The display panel is coupled to the support frame such that a portion of the non-display area is bent with respect to the display area.

Claims (44)

1. A display device, comprising:

a display panel including,

a flexible upper substrate,

at least one light emitting diode, and

a flexible lower substrate, the display panel having a display area corresponding to the light emitting diode, and a non-display area other than the display area; and

a support frame coupled to the display panel,

wherein the display panel is coupled to the support frame such that a portion of the non-display area is bent with respect to the display area.

2. The display device according to claim 1 , wherein the display panel has a square or rectangular shape, and at least one selected from left, right, upper and lower areas of the display panel has a bent structure and is coupled to the support frame.

3. The display device according to claim 1 , wherein the display area of the display panel has a bent portion,

wherein the bent portion of the display area is oriented downwards with respect to a remaining non-bent portion of the display area to provide the display area both at a front surface of the display panel and at side surfaces thereof.

4. The display device according to claim 1 , wherein the display panel is configured such that at least two corner areas are chamfered, and a side area of the display panel corresponding to two chamfered corner areas is bent and is coupled to the support frame 95 .

5. The display device according to claim 4 , wherein the side area of the display panel corresponding to the two chamfered corner areas includes,

a non-display area having a sealing line, and

a portion of the display area, and

wherein the side area is bent downwards from the remaining non-bent portion of the display area such that the display area is both at a front surface of the display panel and at a side surface thereof.

6. The display device according to claim 3 , wherein the display panel is configured such that the bent portion of the display area and the bent portion of the non-display area extending from the bent portion of the display area are bent inwards with respect to the remaining non-bent portion of the display area to have an L-shaped cross-section.

7. The display device according to claim 1 , further comprising:

a fastener interposed between a non-bent portion of the flexible lower substrate and the bent portion of the non-display area,

wherein the bent portion of the non-display area is secured in a bent structure to the non-bent portion of the flexible lower substrate by the fastener.

8. The display device according to claim 7 , wherein the fastener comprises:

a spacer disposed in a space defined between the non-bent portion of the flexible lower substrate and the bent portion of the non-display area to maintain a distance therebetween; and

an adhesive layer attached or applied to the spacer.

9. The display device according to claim 1 , wherein the non-display area comprises:

a bezel area having a sealing line provided along a perimeter of the display area to bond the upper substrate and the lower substrate to each other and seal the upper and lower substrates; and

a pad area being a portion of the lower substrate that protrudes outwards from the upper substrate and having an area to which an integrated circuit chip for applying a control signal to the display area is mounted,

wherein at least a portion of the bent portion of the non-display area includes at least one of a portion of the bezel area and the pad area.

10. The display device according to claim 3 , wherein the support frame has a side window facing the bent portion of the display area.

11. The display device according to claim 3 , further comprising:

a cover part covering and protecting the front surface of the display panel, the cover part including a window formed at a portion corresponding to at least the display area.

12. The display device according to claim 3 , further comprising:

a skirt part covering and protecting the side surfaces of the display panel, the skirt part including a window formed at a portion corresponding to at least the display area.

13. The display device according to claim 12 , wherein the window is one of an opening, a transparent glass panel and a transparent plastic panel.

14. The display device according to claim 3 , wherein the support frame comprises:

a planar part; and

a bent part formed by bending at least one side edge of the planar part inwards, the bent part having a ‘U’-shaped cross-section, and wherein

the bent portion of the display area and the bent portion of the non-display area are formed along the bent part and are secured to an outer surface of the bent part.

15. The display device according to claim 14 , further comprising

an adhesive layer interposed between the bent part of the support frame and the bent portion of the non-display area, wherein the bent portion of the non-display area is attached to the outer surface of the bent part by the adhesive layer.

16. The display device according to claim 1 , wherein a printed circuit board or a shock absorption member is disposed in a space defined between a non-bent portion of the lower substrate of the display panel and a bottom part of the support frame.

17. The display device according to claim 1 , wherein the support frame comprises:

a planar member, each of opposite side edges of the planar member being parallel to each other and being bent outwards to have an L-shaped cross-section.

18. The display device according to claim 1 , wherein the light emitting diode includes an organic light emitting diode or an electronic ink.

19. The display device according to claim 1 , wherein at least one of the upper substrate and the lower substrate is made of a transparent and flexible polymer material.

20. The display device according to claim 4 , wherein at least two corner areas are chamfered in an L shape.
