Abstract

Disclosed is an electronic device in which a defect, where air bubbles occur in an OCR or a gap space is not filled in a D/B process, is prevented and a gap filling tape is adhered to a display module without a gap, thereby solving a problem where a crack or yellowing occurs in the display module. The electronic device includes a display panel including a first substrate and a second substrate bonded to a portion other than one edge of the first substrate, a panel supporting part supporting the display panel, a cover window attached on a front surface of the second substrate, a housing accommodating the panel supporting part and supporting the cover window, a gap between the one edge of the first substrate and the cover window, and a gap sealing member attached on a side surface of the panel supporting part to seal the gap.

First claim

What is claimed is:

1. An electronic device comprising:
a display panel including a first substrate and a second substrate bonded to each other except for a portion of an edge of the first substrate;
a panel supporting part supporting the display panel;
a cover window attached on the second substrate;
a housing accommodating the panel supporting part and supporting the cover window;
a gap between the edge of the first substrate and the cover window; and
a gap sealing member including a front side gap sealing part and a lateral side gap sealing part vertically extended from the front gap sealing part, wherein the front side gap sealing part faces the cover window and the lateral side gap sealing part is attached on a side surface of the panel supporting part to seal the gap.

2. The electronic device of claim 1 , further comprising a driving integrated circuit on the edge of the first substrate, wherein the gap is disposed between the cover window and an area of the edge of the first substrate where the driving integrated circuit is not located.

3. The electronic device of claim 2 , wherein the front side gap sealing part of the gap sealing member
includes an adhesive surface attached with a sealing pad
and overlapping the gap, wherein both edges of the lateral side gap sealing part surround the side surface of the panel supporting part.

4. The electronic device of claim 3 , wherein the adhesive surface is a single sided tape.

5. The electronic device of claim 3 , wherein
the front side gap sealing part overlaps the edge of the first substrate and the lateral side gap sealing part has first and second extension portions,
wherein the first extension portion is extended from one end of the front side gap sealing part to surround one side surface of the panel supporting part, and
the second extension portion from another end of the front portion to surround another side surface of the panel supporting part.

6. The electronic device of claim 5 , wherein the the front side gap sealing part and the lateral side gap sealing part are separated by a first bending guider between the front portion and the first extension portion and a second bending guider between the front portion and the second extension portion.

7. The electronic device of claim 6 , wherein each of the first and second bending guiders includes a groove line between the front portion and the first extension portion and the front portion and the second extension portion, respectively.

8. The electronic device of claim 3 , wherein the sealing pad includes an opening vertically overlapping the driving integrated circuit.

9. The electronic device of claim 2 , further comprising a pair of sealing pads in parallel attached on an adhesive surface of the front side gap sealing part and overlapping the gap, wherein the driving integrated circuit is disposed between the pair of sealing pads.

10. The electronic device of claim 3 , further comprising a pad part at the edge of the first substrate, and the sealing pad is disposed at the portion of the edge of the first substrate where the driving integrated circuit and the pad part are not located.

11. An electronic device comprising:
a display panel having first and second substrates bonded to each other, the first substrate having an edge portion not bonded to the second substrate;
a panel supporting part supporting the display panel;
a housing accommodating the panel supporting part including the display panel; and
a gap sealing member including a front side gap sealing part and a lateral side gap sealing part vertically extended from the front gap sealing part, wherein the front gap sealing part faces an opposite direction to the display panel and the side gap sealing part is attached to a side surface of the panel supporting part to seal a gap between the display panel and the housing.

12. The electronic device of claim 11 , further comprising a sealing pad attached to an adhesive surface of the the front side gap sealing part.

13. The electronic device of claim 11 , wherein the lateral side gap sealing part surrounds a bottom surface of the panel supporting part in addition to the side surface of the panel supporting part.

14. The electronic device of claim 11 , further comprising a driving integrated circuit in close proximity to the edge portion of the first substrate.

15. The electronic device of claim 12 , wherein the adhesive surface includes a single sided tape.

16. The electronic device of claim 11 , wherein
the front side gap sealing part overlaps the edge of the first substrate and the lateral side gap sealing part has first and second extension portions,
wherein the first extension portion is extended from one end of the front side gap sealing part to surround one side surface of the panel supporting part, and
the second extension portion from another end of the front portion to surround another side surface of the panel supporting part.

17. The electronic device of claim 16 , wherein the the front side gap sealing part and the lateral side gap sealing part are separated by a first bending guider between the front portion and the first extension portion and a second bending guider between the front portion and the second extension portion.

18. The electronic device of claim 17 , wherein each of the first and second bending guiders includes a groove line between the front portion and the first extension portion and the front portion and the second extension portion, respectively.

19. The electronic device of claim 14 , further comprising a pair of sealing pads in parallel attached on an adhesive surface of the base member the front side gap sealing part, wherein the driving integrated circuit is disposed between the pair of sealing pads.

20. The electronic device of claim 12 , further comprising a pad part at the edge portion of the first substrate, and the sealing pad is disposed at the edge portion of the first substrate where the driving integrated circuit and the pad part are not located.
