Abstract

A bottom sash of a display module is provided. The bottom sash includes a bead part formed by depressing some portions of the bottom sash toward a rear side, and a reinforcing panel attached to a front surface of the bottom sash and spaced apart from the bead part.

Claims

1. A display module comprising:

a display panel;

a backlight unit disposed at a rear side of the display panel;

a middle mold configured to support the display panel and the backlight unit spaced apart from each other;

a top chassis provided at a front side of the middle mold, and configured to support a rim of a front side of the display panel; and

a bottom chassis on which the backlight unit is installed, and which is provided at a rear side of the middle mold,

wherein the bottom chassis has at least one depressed portion depressed toward a rear side of the bottom chassis, and a panel attached to a front surface of the bottom chassis through an adhesive material.

2. The display module of claim 1, wherein the at least one depressed portion comprises a plurality of depressed portions.

3. The display module of claim 2, wherein the plurality of the depressed portions extend in upper and lower side directions.

4. The display module of claim 3, wherein the plurality of depressed portions are spaced apart from each other in left and right side directions.

5. The display module of claim 2, wherein the plurality of depressed portions are spaced apart from each other in left and right side directions and in upper and lower side directions.

6. The display module of claim 1, wherein the adhesive material includes a double-sided tape.

7. The display module of claim 1, wherein the bottom chassis and the panel are formed of a metallic material so that the panel thermally expands in a same manner as the bottom chassis.

8. A display apparatus, comprising the display module of claim 1.

9. The display module of claim 1, wherein the backlight unit is supported by the bottom chassis.

10. The display module of claim 1, wherein the panel is configured to reinforce a strength of the bottom chassis.

11. The display module of claim 1, wherein the panel is formed of a metallic material which thermally expands.

12. The display module of claim 1, wherein the panel is attached to the front surface of the bottom chassis except for the at least one depressed portion.

13. The display module of claim 12, wherein the adhesive material is attached to cover an entire area of the front surface of the bottom chassis adjacent to the at least one depressed portion.

14. The display module of claim 6, wherein the double-sided tape is attached to cover an entire area of the front surface of the bottom chassis adjacent to the at least one depressed portion.

15. The display module of claim 1, wherein the adhesive material is not attached to the at least one depressed portion.

24. A display apparatus, comprising the display module of claim 10.

31. The display apparatus of claim 24, wherein the adhesive material is attached to cover an entire area of the front surface of the bottom chassis adjacent to the at least one depressed portion.

32. The display apparatus of claim 24, wherein the least one depressed portion comprises a plurality of depressed portions.

34. The display apparatus of claim 32, wherein the plurality of depressed portions are regularly arranged on the bottom chassis.

16. A display module comprising:

a bottom chassis forming a rear surface of the display module,

wherein the bottom chassis comprises;

at least one depressed portion formed by depressing at least one portion of the bottom chassis towards a rear side of the display module, and

a panel attached to a front surface of the bottom chassis through an adhesive material.

17. The display module of claim 16, further comprising:

a display panel configured to display an image; and

a backlight unit configured to supply light to the display panel,

wherein the display panel comprises a liquid crystal display panel.

18. The display module of claim 16, further comprising a display panel configured to display an image,

wherein the display panel comprises an organic light emitting diode panel.

19. The display module of claim 16, wherein the adhesive material comprises a double-sided tape.

20. The display module of claim 16, wherein the least one depressed portion comprises a plurality of depressed portions.

21. The display module of claim 20,

wherein each of the plurality of depressed portions extends in upper and lower side directions, and

the plurality of the depressed portions are spaced apart from each other in left and right side directions.

22. The display module of claim 20,

wherein the plurality of the depressed portions are spaced apart from each other in left and right side directions and upper and lower side directions.

23. The display module of claim 16, wherein the bottom chassis and the panel are formed of a metallic material so that the panel thermally expands in a same manner as the bottom chassis.

25. The display module of claim 16, wherein the panel is configured to reinforce a strength of the bottom chassis.

26. The display module of claim 16, wherein the panel is formed of a metallic material which thermally expands.

27. The display module of claim 16, wherein the panel is attached to the front surface of the bottom chassis except for the at least one depressed portion.

28. The display module of claim 27, wherein the adhesive material is attached to cover an entire area of the front surface of the bottom chassis adjacent to the at least one depressed portion.

29. The display module of claim 19, wherein the double-sided tape is attached to cover an entire area of the front surface of the bottom chassis adjacent to the at least one depressed portion.

30. The display module of claim 16, wherein the adhesive material is not attached to the at least one depressed portion.

33. The display apparatus of claim 20, wherein the plurality of depressed portions are regularly arranged on the bottom chassis.
