Abstract

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

Claims

1. A display apparatus comprising:

an organic light emitting diode panel;

a chassis disposed at a rear side of the organic light emitting diode panel; and

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

wherein the chassis includes a plurality of depressed portions spaced apart from a rear surface of the panel, and

wherein each of the plurality of depressed portions comprises a side wall portion and a bottom portion.

2. The display apparatus of claim 1, wherein the adhesive material comprises a double-sided tape.

3. The display apparatus of claim 2, wherein the panel is attached to an entire area of the front surface of the chassis, except for the plurality of depressed portions, through the double-sided tape.

4. The display apparatus of claim 2, wherein the double-sided tape is not attached to the plurality of depressed portions.

5. The display apparatus of claim 1, wherein the plurality of depressed portions are spaced apart from each other at regular intervals.

6. The display apparatus of claim 1, 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.

7. The display apparatus of claim 1, 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.

8. The display apparatus of claim 1, wherein the chassis and the panel are formed of a metallic material.

9. The display apparatus of claim 8, wherein the panel is configured to reinforce a strength of the chassis.

10. The display apparatus of claim 8, wherein the panel is configured to radiate heat generated by the display apparatus.

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

12. A display apparatus comprising:

an organic light emitting diode panel;

a chassis; and

a panel provided between the organic light emitting diode panel and the chassis, the panel being directly attached to a surface of the chassis through an adhesive material,

wherein the surface of chassis includes at least one depressed portion that is depressed in a direction extending away from the panel.

13. The display apparatus of claim 12, wherein the adhesive material comprises a double-sided tape.

14. The display apparatus of claim 13, wherein the double-sided tape is not attached to the at least one depressed portion.

15. The display apparatus of claim 12, wherein the panel is not attached to the surface of the chassis, through the adhesive material, at the at least one depressed portion.

16. The display apparatus of claim 13, wherein the panel is attached to an entire area of the surface of the chassis, except for the at least one depressed portion, through the double-sided tape.
