Abstract

An organic light emitting diode display includes a panel assembly having a display section and a pad section, and a bezel that couples with the panel assembly. The bezel includes a back on which the panel assembly is placed, side walls located at an edge of the back of the bezel, and a protrusion reinforcing portion formed at a region corresponding to the pad section and a vicinity of the pad section in the back of the bezel.

Claims

1. An organic light emitting diode display, comprising:

a panel assembly having a display section and a pad section; and

a bezel that couples with the panel assembly,

wherein the bezel comprises;

a back on which the panel assembly is placed,

side walls located at the edges of the back, and

a protrusion reinforcing portion formed in the back at a region corresponding to the pad section and in the vicinity of the pad section.

2. The organic light emitting diode display of claim 1, wherein:

the side walls include a first side wall corresponding to the pad section and second side walls, and

the protrusion reinforcing portion is formed in parallel with the first side wall.

3. The organic light emitting diode display of claim 2, wherein:

an open section that is located in parallel with the first side wall is formed in the bezel and exposes the edge of the back, and

the height of the first side wall is lower than that of the second side walls.

4. The organic light emitting diode display of claim 1, wherein:

the panel assembly includes the display section, a first substrate formed with the pad section, and a second substrate to be fixed to the first substrate while covering the display section, and

the protrusion reinforcing portion is spaced apart from an edge of the second substrate facing the pad section toward the display section.

5. The organic light emitting diode display of claim 4, wherein the protrusion reinforcing portion protrudes toward the panel assembly at a predetermined distance from the first substrate.

6. The organic light emitting diode display of claim 5, further comprising a buffer plate located between the panel assembly and the bezel, wherein the thickness of the buffer plate is larger than the height of the protrusion reinforcing portion.

7. The organic light emitting diode display of claim 6, wherein the buffer plate has an opening at a position corresponding to the protrusion reinforcing portion.

8. The organic light emitting diode display of claim 6, wherein the protrusion reinforcing portion is formed in two lines at a distance from each other.

9. The organic light emitting diode display of claim 8, wherein the buffer plate has two openings, each corresponding to the protrusion reinforcing portion formed in two lines.

10. The organic light emitting diode display of claim 4, wherein the protrusion reinforcing portion protrudes in a direction away from the panel assembly.

11. The organic light emitting diode display of claim 10, further comprising a buffer plate located between the panel assembly and the bezel.

12. The organic light emitting diode display of claim 11, wherein the protrusion reinforcing portion is formed in two lines at a distance from each other.

13. The organic light emitting diode display of claim 1, wherein:

the panel assembly includes the display section, a first substrate formed with the pad section, and a second substrate to be fixed to the first substrate while covering the display section, and

the protrusion reinforcing portion is located at a region corresponding to the pad section.

14. The organic light emitting diode display of claim 13, wherein the protrusion reinforcing portion is in two sections located at corners of the back.

15. The organic light emitting diode display of claim 14, wherein the protrusion reinforcing portion protrudes toward the panel assembly at a distance from the first substrate.

16. The organic light emitting diode display of claim 15, further comprising a buffer plate located between the panel assembly and the bezel, wherein the thickness of the buffer plate is larger than the height of the protrusion reinforcing portion.

17. The organic light emitting diode display of claim 16, wherein a cutout accommodating the protrusion reinforcing portion is formed in the buffer plate.

18. The organic light emitting diode display of claim 14, wherein the protrusion reinforcing portion protrudes in a direction away from the panel assembly.

19. The organic light emitting diode display of claim 18, further comprising a buffer plate located between the panel assembly and the bezel.

20. The organic light emitting diode display of claim 1, wherein the side walls are folded twice or more.

21. The organic light emitting diode display of claim 1, wherein the bezel is formed of a rigid metal material.

22. The organic light emitting diode display of claim 1, wherein the back, side walls and protrusion reinforcing portion of the bezel are integrally formed from one metal plate.

23. The organic light emitting diode display of claim 1, wherein the back and side walls of the bezel are integrally formed from one metal plate and the protrusion reinforcing portion is a metal bar joined to the back.

24. The organic light emitting diode display of claim 2, wherein the protrusion reinforcing portion is formed on the back below the center line of the back.

25. The organic light emitting diode display of claim 3, wherein open sections are formed at either end of the first side wall adjacent to second side walls and expose the edge of the back.

26. The organic light emitting diode display of claim 25, wherein the protrusion reinforcing portion extends over the open sections and the first side wall.

27. The organic light emitting diode display of claim 25, wherein the protrusion reinforcing portion extends over the first side wall.

28. The organic light emitting diode display of claim 25, wherein the protrusion reinforcing portion is in two sections located at corners of the back and extending over the open sections.

29. The organic light emitting diode display of claim 25, wherein the protrusion reinforcing portion is formed in two lines at a distance from each other.

30. The organic light emitting diode display of claim 29, wherein one of the lines is in two sections located at the lower corners of the back.

31. The organic light emitting diode display of claim 6, wherein the buffer plate is formed of a buffer layer and adhesive layers on both sides of the buffer layer.

32. The organic light emitting diode display of claim 31, wherein the buffer layer is formed of a flexible material.

33. The organic light emitting diode display of claim 32, wherein the flexible material is a sponge or a polyurethane foam.

34. The organic light emitting diode display of claim 10, wherein the buffer layer is continuous in the region of the protrusion reinforcing portion.
