Abstract

A display device and a method of manufacturing the same are provided. A display device includes: a light guide plate on a rear surface of a display panel, the light guide plate being configured to direct light toward the display panel, a reflector on a rear surface of the light guide plate, the reflector being configured to reflect light from a rear of the light guide plate toward a front surface of the light guide plate, a back cover on a rear surface of the reflector, and a light-emitting diode array coupled to an edge of the back cover, the light-emitting diode array including: a printed circuit board, and a plurality of light-emitting diodes at a side surface of an edge of the light guide plate, the plurality of light-emitting diodes being configured to generate light, the plurality of light emitting diodes being attached to the printed circuit board.

Claims (32)

1. A display device, comprising:

a light guide plate on a rear surface of a display panel, the light guide plate being configured to direct light toward the display panel;

a reflector on a rear surface of the light guide plate, the reflector being configured to reflect light from a rear of the light guide plate toward a front surface of the light guide plate;

a back cover on a rear surface of the reflector;

a light-emitting diode array coupled to an edge of the back cover, the light-emitting diode array comprising:

a printed circuit board; and

a plurality of light-emitting diodes at a side surface of an edge of the light guide plate, the plurality of light-emitting diodes being configured to generate light, the plurality of light emitting diodes being attached to the printed circuit board; and

a support member comprising:

a front surface configured to support a rear surface of the back cover; and

a side surface configured to support the light-emitting diode array.

2. The display device of claim 1 , wherein a side surface of the light-emitting diode array is fixedly coupled to a side surface of the edge of the back cover via a bonding member.

3. The display device of claim 1 , wherein the support member is coupled to at least one of: a side surface of the light-emitting diode array and the rear surface of the back cover.

4. The display device of claim 3 , wherein the plurality of light-emitting diodes of the light-emitting diode array are fixedly coupled to the side surface of the edge of the light guide plate via a transparent bonding member.

5. The display device of claim 1 , wherein the curable resin comprises one or more of: a naturally curable resin, an ultraviolet curable resin, and a thermally curable resin.

6. The display device of claim 1 , wherein the light-emitting diode array is fixedly coupled to the side surface of the edge of the light guide plate via a transparent bonding member.

7. The display device of claim 1 , wherein the support member is coupled to at least one of: a side surface of the light-emitting diode array and the rear surface of the back cover.

8. A method of manufacturing a display device, the method comprising:

providing a light guide plate on a rear surface of a display panel to direct light toward the display panel;

providing a reflector on a rear surface of the light guide plate to reflect light from a rear of the light guide plate toward a front surface of the light guide plate;

providing a back cover on a rear surface of the reflector;

coupling a light-emitting diode array to an edge of the back cover, the coupling the light-emitting diode array comprising:

providing a printed circuit board; and

providing a plurality of light-emitting diodes at a side surface of an edge of the light guide plate to generate light, the plurality of light-emitting diodes being attached to the printed circuit board; and

providing a support member comprising:

providing a front surface supporting a rear surface of the back cover; and

providing a side surface supporting the light-emitting diode array.

9. The method of claim 8 , further comprising fixedly coupling a side surface of the light-emitting diode array to a side surface of the edge of the back cover via a bonding member.

10. The method of claim 8 , wherein the support member is coupled to at least one of: a side surface of the light-emitting diode array and the rear surface of the back cover.

11. The method of claim 10 , further comprising fixedly coupling the plurality of light-emitting diodes of the light-emitting diode array to the side surface of the edge of the light guide plate via a transparent bonding member.

12. The method of claim 11 , wherein the curable resin comprises one or more of: a naturally curable resin, an ultraviolet curable resin, and a thermally curable resin.

13. The method of claim 11 , further comprising fixedly coupling the light-emitting diode array to the side surface of the edge of the light guide plate via a transparent bonding member.

14. The method of claim 11 , further comprising coupling the support member to at least one of: a side surface of the light-emitting diode array and the rear surface of the back cover.
