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:

a display panel;

a chassis disposed behind a rear side of the display panel; and

a panel provided at a front surface of the chassis and configured to reinforce a strength of the chassis,

wherein the chassis includes;

a front portion attached to a rear surface of the panel using an adhesive material; and

a plurality of depressed portions that are depressed towards a rear side of the display apparatus, and

wherein each of the plurality of depressed portions includes;

a bottom portion that is spaced apart from the rear surface of the panel by an air gap; and

a plurality of side portions connecting the front portion and the bottom portion.

2. The display apparatus of claim 1, wherein the front portion is an entire area of the front surface of the chassis, except for the plurality of depressed portions.

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

wherein the double-sided tape is not attached to the plurality of depressed portions.

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

5. The display apparatus of claim 1, wherein each of the plurality of depressed portions extends in a horizontal direction.

6. The display apparatus of claim 1, wherein the plurality of depressed portions are spaced apart from each other in left and right side directions and upper and lower side directions.

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

8. The display apparatus of claim 7, wherein the panel is configured to radiate heat generated by the display apparatus.

9. The display apparatus of claim 1, further comprising a rear cover disposed behind a rear side of the chassis.

10. The display apparatus of claim 1, wherein a rear surface of the chassis is depressed towards a front side of the display apparatus at an area corresponding to the front portion of the chassis.

11. A display module comprising:

a display panel;

a chassis; and

a panel fixed to the chassis to reinforce a strength of the chassis,

wherein the chassis includes;

a front portion fixed to a rear surface of the panel; and

at least one depressed portion that is depressed towards a rear side of the display module, and

wherein the at least one depressed portion includes;

a bottom portion that is spaced apart from the rear surface of the panel by an air gap; and

a plurality of side portions connecting the front portion and the bottom portion.

12. The display module of claim 11, wherein the panel is fixed to a front surface of the front portion using an adhesive material.

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

14. The display module of claim 12, wherein the panel is not fixed to a surface of the at least one depressed portion using the adhesive material.

15. The display module of claim 11, further comprising a rear cover disposed behind a rear side of the chassis,

wherein the rear cover forms a rear surface of the display module.

16. The display module of claim 11, wherein a rear surface of the chassis is depressed towards a front side of the display module at an area corresponding to the front portion of the chassis.
