Abstract

A display module includes a display panel, a diffusion plate, a bottom chassis, and a transparent spacer made having a diffusion pattern formed thereon disposed on the bottom chassis to support the diffusion plate.

Claims

1. A display module comprising:

a display panel;

a diffusion plate;

a bottom chassis; and

a spacer disposed on the bottom chassis configured to support the diffusion plate,

wherein

the spacer includes a first region configured to permit light transmission through the spacer, and a second region with a diffusion pattern configured to diffuse light.

2. The display module according to claim 1, wherein the spacer comprises a plurality of spacers disposed apart from each other on the bottom chassis.

3. The display module according to claim 1, wherein the diffusion pattern is formed by a plurality of grooves concavely formed on an outer surface of the spacer.

4. The display module according to claim 3, wherein the plurality of grooves extends parallel to a rear surface of the bottom chassis.

5. The display module according to claim 1, wherein the diffusion pattern is formed by a plurality of protrusions convexly formed on an outer surface of the spacer.

6. The display module according to claim 5, wherein the plurality of protrusions extends parallel to a rear surface of the bottom chassis.

7. The display module according to claim 1, wherein:

the spacer is formed in a plate shape which has a width gradually narrowing from the bottom chassis toward the diffusion plate; and

the diffusion pattern is formed on surfaces of the spacer.

8. The display module according to claim 7, wherein the spacer is formed in a triangular plate shape.

9. The display module according to claim 1, wherein the spacer comprises a support portion arranged at a bottom chassis side end portion of the spacer configured to be disposed on an inner surface of the bottom chassis.

10. The display module according to claim 9, wherein a surface of the support portion of the spacer facing the diffusion plate is white.

11. The display module according to claim 1, wherein:

the spacer comprises a catching portion configured to pass through the bottom chassis, and

the bottom chassis comprises a catching hole through which the catching portion passes.

12. A display apparatus comprising:

a display module, wherein the display module comprises;

a display panel;

a diffusion plate;

a bottom chassis; and

a spacer disposed on the bottom chassis configured to support the diffusion plate, and wherein

the spacer includes a first region configured to permit light transmission through the spacer, and a second region with a diffusion pattern configured to diffuse light.

13. The display apparatus according to claim 12, wherein the spacer comprises a plurality of spacers disposed apart from each other on the bottom chassis.

14. The display apparatus according to claim 12, wherein the diffusion pattern is formed by a plurality of grooves concavely formed on an outer surface of the spacer.

15. The display apparatus according to claim 14, wherein the plurality of grooves extends parallel to a rear surface of the bottom chassis.

16. The display apparatus according to claim 12, wherein the diffusion pattern is formed by a plurality of protrusions convexly formed on an outer surface of the spacer.

17. The display apparatus according to claim 16, wherein the plurality of protrusions extends parallel to a rear surface of the bottom chassis.

18. The display apparatus according to claim 12, wherein:

the spacer is formed in a plate shape which has a width gradually narrowed as advancing from the bottom chassis toward the diffusion plate; and

the diffusion pattern is formed on both surfaces of the spacer.

19. The display apparatus according to claim 18, wherein the spacer is formed in a triangular plate shape.

20. The display apparatus according to claim 12, wherein the spacer comprises a support portion arranged at a bottom chassis side end portion of the spacer configured to be disposed on an inner surface of the bottom chassis.

21. The display apparatus according to claim 20, wherein a surface of the support portion of the spacer facing the diffusion plate is white.

22. The display apparatus according to claim 12, wherein:

the spacer comprises a catching portion configured to pass through the bottom chassis, and

the bottom chassis comprises a catching hole through which the catching portion passes.

23. A spacer of a display module configured to be disposed on a chassis of the display module and configured to support a diffusion plate of the display module, the spacer comprising:

a base configured to be disposed on the chassis;

a spacer portion extending from the base and configured to extend from the base to the diffusion plate; and

a diffusion pattern formed in the spacer portion configured to diffuse light transmitted through the spacer.

24. The spacer according to claim 23, wherein the diffusion pattern is formed in a lower portion of the spacer portion extending a distance from the base that is less than a length of the spacer portion.

25. The spacer according to claim 24, further comprising:

a catch portion configured to extend from the base towards the chassis and configured to seat the spacer in the chassis.

26. The spacer according to claim 25, wherein the base is circular shaped and the spacer portion is triangular shaped.

27. The spacer according to claim 26, wherein the base is white.

28. The spacer according to claim 26, wherein the spacer is transparent.
