Abstract

Provided is a display apparatus. The display apparatus includes a display panel, a light source configured to generate light to be supplied to the display panel, and a reflecting member disposed behind the display panel and formed of a white foam resin to diffuse and reflect light generated from the light source.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel comprising a front side, facing a first direction, and a rear side, facing a second direction;
a light source disposed in the second direction with respect to the rear side of the display panel, on a lower portion of the display panel, wherein the light source is positioned such that it radiates light upward and in the second direction, in an inclined manner, such that the light radiated from the light source is directed away from the rear side of the display panel; and
a reflecting member disposed in the second direction with respect to the rear side of the display panel and comprising a white foam resin;
wherein the reflecting member comprises:
a first reflecting surface, substantially facing the first direction,
a pair of second reflecting surfaces which are provided on both sides of the first reflecting surface and extend in front of the first reflecting surface in an inclined manner; and
a light absorbing part, disposed on each of the pair of second reflecting surfaces, and configured to absorb some light incident on the pair of second reflecting surfaces.

2. The display apparatus according to claim 1 , wherein:
the first reflecting surfaces comprises a reflecting groove which is concavely provided on a front surface of the first reflecting surface to reflect light radiated from the light source.

3. The display apparatus according to claim 2 , wherein the light source comprises:
a printed circuit board which has a bar shape and is disposed lengthwise in a horizontal direction on the rear side of the lower portion of the display panel; and
a plurality of light emitting diodes disposed on the printed circuit board.

4. The display apparatus according to claim 3 , wherein:
the first reflecting surface extends toward an upper front side around the printed circuit board in an inclined manner; and
the pair of second reflecting surfaces are provided on both sides around the printed circuit board.

5. The display apparatus according to claim 1 , wherein the light absorbing part comprises a plurality of grooves concavely formed as depressions in each of the pair of the second reflecting surfaces.

6. The display apparatus according to claim 5 , wherein the light source comprises a printed circuit board which has a bar shape and is disposed lengthwise in a horizontal direction on the rear side of the lower portion of the display panel, and a plurality of light emitting diodes disposed on the printed circuit board; and
wherein the plurality of grooves gradually become smaller in size from a region adjacent to a side end of the printed circuit board toward a region spaced apart from the printed circuit board.

7. The display apparatus according to claim 1 , wherein the light absorbing part comprises a plurality of black dots provided on the pair of the second reflecting surfaces.

8. The display apparatus according to claim 7 , wherein
the light source comprises a printed circuit board which has a bar shape and is disposed lengthwise in a horizontal direction on the rear side of the lower portion of the display panel, and a plurality of light emitting diodes disposed on the printed circuit board; and
the plurality of black dots gradually become smaller in size from a region adjacent to a side end of the printed circuit board toward a region spaced apart from the printed circuit board.

9. The display apparatus according to claim 1 , further comprising:
a middle mold configured to support an outer perimeter of the display panel;
a top chassis combined with a front side of the middle mold; and
a bottom chassis combined with the rear side of the middle mold,
wherein the reflecting member is disposed inside the bottom chassis.

10. The display apparatus according to claim 1 , further comprising:
a middle mold configured to support an outer perimeter of the display panel; and
a top chassis combined with a front side of the middle mold,
wherein the reflecting member forms a bottom chassis to be combined with the rear side of the middle mold.

11. The display apparatus according to claim 3 , wherein the light source further comprises a reflector configured to reflect light radiated from the light emitting diodes, and the reflector extends toward an upper rear side of the light emitting diodes in an inclined manner.

12. The display apparatus according to claim 11 , wherein the reflector is configured to extend in an arcuate shape.

13. A display apparatus comprising:
a display panel comprising a front side, facing a first direction, and a rear side, facing a second direction;
a light source disposed in the second direction with respect to the rear side of the display panel, on a lower portion of the display panel, wherein the light source is positioned such that it radiates light upward and in the second direction, in an inclined manner, such that the light radiated from the light source is directed away from the rear side of the display panel; and
a bottom chassis which accommodates the light source and comprises a white foam resin;
wherein the bottom chassis comprises:
a first reflecting surface, substantially facing the first direction, and
a pair of second reflecting surfaces which are provided on both sides of the first reflecting surface and extend in front of the first reflecting surface in an inclined manner, and
a light absorbing part disposed on each of the pair of second reflecting surfaces and configured to absorb come light incident on the pair of second reflecting surfaces.

14. The display apparatus according to claim 13 , wherein the light source comprises:
a printed circuit board; and
a plurality of light emitting diodes disposed on the printed circuit board.

15. The display apparatus according to claim 14 , wherein:
the printed circuit board is formed in a bar shape and disposed lengthwise in a horizontal direction on the rear side of the lower portion of the display panel.

16. The display apparatus according to claim 15 , wherein the light absorbing part comprises a plurality of grooves concavely formed as depressions.

17. The display apparatus according to claim 16 , wherein the plurality of grooves gradually become smaller in size from a region adjacent to a side end of the printed circuit board toward a region spaced apart from the printed circuit board.

18. The display apparatus according to claim 15 , wherein the light absorbing part comprises a plurality of black dots.

19. The display apparatus according to claim 18 , wherein the plurality of black dots gradually become smaller in size from a region adjacent to a side end of the printed circuit board toward a region spaced apart from the printed circuit board.
