Abstract

Disclosed are a backlight unit and a display device having the same. The backlight unit comprises a light emitting diode (LED) module comprising an LED, a case supporting the LED module and comprising a bending part that guides and fixes an end portion of the LED module, and a fixing part fixing the LED module to the case.

Claims

1. A backlight unit comprising:

a light emitting diode (LED) module comprising an LED;

a case supporting the LED module, and comprising a bending part that guides and fixes an end portion of the LED module; and

a fixing part fixing the LED module to the case.

2. The backlight unit as claimed in claim 1, wherein the LED module comprises a printed circuit board, the LED on the printed circuit board, and a mold part on the LED.

3. The backlight unit as claimed in claim 1, wherein the bending part has a length substantially identical to or shorter than a length of the LED module, and is located corresponding to a fixing position of the LED module.

4. The backlight unit as claimed in claim 1, wherein the bending part comprises at least one bent area formed corresponding to a fixing position of the LED module.

5. The backlight unit as claimed in claim 1, wherein the case is formed of a SUS material.

6. The backlight unit as claimed in claim 1, comprising a reflective sheet on the LED module comprising an opening such that the LED is exposed.

7. The backlight unit as claimed in claim 6, wherein the reflective sheet reflects light emitted from the LED upward.

8. The backlight unit as claimed in claim 1, wherein the fixing part fixes the LED module to the case in another end area of the LED module in which the bending part is not formed.

9. The backlight unit as claimed in claim 1, wherein the bending part is integrated with the case.

10. The backlight unit as claimed in claim 1, wherein the bending part is formed with a member separated from the case.

11. The backlight unit as claimed in claim 1, wherein the LED module is formed as the plural number, and at least one LED module comprises a plurality of LEDs.

12. The backlight unit as claimed in claim 1, wherein the LED module is formed as the plural number, and each LED module comprises an LED.

13. A display device comprising:

a backlight unit comprising a light emitting diode (LED) module comprising an LED, a case supporting the LED module, and comprising a bending part that guides and fixes an end portion of the LED module; and

a fixing part fixing the LED module to the case; and

a display part displaying an image.

14. The display device as claimed in claim 13, wherein the display part is a liquid crystal panel.

15. The display device as claimed in claim 13, wherein the LED module comprises a printed circuit board, the LED on the printed circuit board, and a mold part on the LED.

16. The display device as claimed in claim 13, wherein the bending part has a length identical to or shorter than a length of the LED module, and is located corresponding to a fixing position of the LED module.

17. The display device as claimed in claim 13, wherein the bending part comprises at least one bent area formed corresponding to a fixing position of the LED module.

18. The display device as claimed in claim 13, comprising a reflective sheet on the LED module comprising an opening such that the LED is exposed.

19. The display device as claimed in claim 13, wherein the fixing part fixes the LED module to the case in another end area of the LED module in which the bending part is not formed.

20. The display device as claimed in claim 13, wherein the bending part is formed integrally with or separately from the case.
