Abstract

The present disclosure relates to a display apparatus that reflects light emitted from a light source to a display panel side through a reflecting member without having a configuration corresponding to a light guide plate, in which light emitted from a light source substantially uniformly reaches a reflecting member, a corner member may be disposed on the corner side of the cover member where the light source module is not disposed so that the light incident on the corner side is reflected toward the display panel side to irradiate light to the display panel side.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel comprising a pair of first sides and a pair of second sides;
a cover configured to support the display panel;
a light source module comprising a light source and extending along at least one of the pair of first sides of the display panel, said light source module being disposed adjacent to at least one of the pair of first sides;
a first reflecting member comprising a reflective surface configured to reflect light emitted from the light source module toward the display panel;
a second reflecting member comprising a reflective surface configured to reflect the light emitted from the light source module toward the first reflecting member; and
at least one corner members comprising a reflective surface disposed between the pair of second sides and one end of the light source module in longitudinal direction.

2. The display apparatus of claim 1 , wherein the at least one corner member is configured to reflect incident light toward at least one of: the first reflecting member, the second reflecting member, or the display panel.

3. The display apparatus of claim 1 , further comprising a chassis disposed in a front direction of the display panel configured to display an image thereon,
wherein the cover comprises a coupling portion extending forward from both ends of the cover corresponding to the pair of second sides and configured to be coupled with the chassis, and the cover further comprises an inclined portion extending backward from the coupling portion and inclined with respect to the coupling portion, and
the at least one corner member being disposed to be in contact with the coupling portion and the inclined portion.

4. The display apparatus of claim 3 , wherein the cover further comprises a support portion extending from the coupling portion and configured to support the display panel, and
the at least one corner member being disposed in a space between the coupling portion, the inclined portion, and the support portion.

5. The display apparatus of claim 4 , wherein the cover further comprises a resting surface extending from one edge of at least one of: the coupling portion, the inclined portion, and the support portion, and formed in the space, and the at least one corner member is configured to rest on the resting surface.

6. The display apparatus of claim 5 , wherein the at least one corner member further comprises a hook portion configured to engage the resting surface.

7. The display apparatus of claim 5 , wherein the resting surface comprises a coupling protrusion protruding upward in a direction in which the pair of second sides extend, and
the corner member further comprises an insertion hole configured to receive the coupling protrusion for insertion.

8. The display apparatus of claim 5 , wherein the at least one corner member is configured to rest along a direction in which the pair of second sides extend.

9. The display apparatus of claim 5 , wherein the at least one corner member further comprises a first surface corresponding to the resting surface and facing upward, and a second surface extending from the first surface in the direction in which the pair of second sides extend and formed along the coupling portion, the inclined portion, and the support portion.

10. The display apparatus of claim 9 , wherein the first surface and the second surface include a white color.

11. The display apparatus of claim 1 , further comprising a printed circuit board (PCB) electrically connected to the display panel,
wherein the at least one corner member comprises a guide portion configured to guide a position of the PCB.

12. The display apparatus of claim 11 , wherein the guide portion comprises a first extending portion extending downward along a direction in which the pair of second sides extend, at one edge of the at least one corner member comes into contact with the resting portion, and a second extending portion bent and extending from the first extending portion, and
wherein the PCB is disposed in space formed between the first extending portion and the second extending portion.

13. The display apparatus of claim 12 , wherein the guide portion is configured to guide the PCB such that a mounting surface on which electrical components are mounted is disposed to face the direction in which the pair of second sides extend.

14. The display apparatus of claim 11 , further comprising:
a support disposed on the cover, and configured to support the light source module and the second reflecting member; and
a gasket configured to electrically connect the support to the PCB.

15. A display apparatus comprising:
a display panel configured to display an image thereon;
a chassis disposed in a front direction of the display panel;
a cover configured to support the display panel, and configured to be coupled with a rear portion of the chassis, the cover including a coupling portion extending forward from both ends of the cover member and configured to be coupled with the chassis, and an inclined portion extending backward from the coupling portion and inclined with respect to the coupling portion;
a light source module comprising a light source disposed behind the display panel, and disposed along a side direction of the display panel; and
a corner member comprising a reflective surface disposed in a corner area between the coupling portion, the inclined portion, and outer portions of both ends of the light source module and configured to reflect light generated from the light source module,
wherein the cover further comprises a resting surface extending from one edge of at least one of the coupling portion and the inclined portion, and formed in the corner area, and the corner member is configured to be hooked to the resting surface.

16. The display apparatus of claim 15 , further comprising:
a first reflecting member comprising a reflective surface disposed on a front surface of the cover member and configured to reflect light irradiated from the light source module toward the display panel; and
a second reflecting member comprising a reflective surface disposed between the light source module and the first reflecting member and configured to reflect light irradiated from the light source module toward the first reflecting member so that the light reflected by the second reflecting member arrives at the first reflecting member,
wherein the corner member reflects incident light toward at least one of: the first reflecting member, the second reflecting member, or the display panel.

17. The display apparatus of claim 15 , further comprising a Printed Circuit Board (PCB) electrically connected with the display panel,
wherein the corner member comprises a guide portion configured to guide a position of the PCB.

18. A display apparatus comprising:
a display panel configured to display an image thereon;
a printed circuit board (PCB) electrically connected to the display panel;
a cover disposed behind the display panel, and configured to support the display panel;
a light source module comprising a light source disposed between the display panel and the cover, and arranged toward the cover;
a first reflecting member comprising a reflective surface disposed in a front direction from the cover, and configured to reflect light emitted from the light source module toward the display panel;
a second reflecting member comprising a reflective surface disposed between the light source module and the first reflecting member, and configured to reflect light emitted from the
