Abstract

A backlight assembly having lamp sockets and a side mold is provided. The backlight assembly includes a lamp emitting light, a lamp socket into which the lamp is inserted, and a side mold having at least one portion of a bottom surface thereof opened and including a supporting portion, a side wall formed at one side of the supporting portion, a sloping portion inclined downwardly at a side opposite to the supporting portion, and at least one socket connection portion receiving the lamp socket.

Claims (46)

1. A backlight assembly comprising:

a lamp emitting light;

a lamp socket into which the lamp is inserted; and

a side mold having at least one portion of a bottom surface thereof opened, the side mold comprising a supporting portion, a side wall formed at one side of the supporting portion, a sloping portion inclined downwardly at a side opposite to the supporting portion, and at least one socket connection portion receiving the lamp socket,

wherein the lamp socket includes a lamp connection portion, a power connection portion, and a light blocking plate positioned at an interface between the lamp connection portion and the power connection portion,

wherein the lamp connection portion, the power connection portion, and the light blocking plate, are integrally formed with each other as a single unitary indivisible unit, and

wherein the light blocking plate protrudes outward from the power connection portion.

2. The backlight assembly of claim 1 , wherein each of the at least one socket connection portion includes an internal surface of the side wall and a lateral surface of the sloping portion.

3. The backlight assembly of claim 2 , wherein the lateral surface of the sloping portion included in each socket connection portion comprises a first locking member, the lamp socket comprises a second locking member coupled to the first locking member, and the lamp socket is combined with the side mold as the first locking member and the second locking member are coupled to each other.

4. The backlight assembly of claim 3 , wherein the first locking member is a locking protrusion and the second locking member is a locking hole.

5. The backlight assembly of claim 3 , wherein the first locking member is a locking hole and the second locking member is a locking protrusion.

6. The backlight assembly of claim 2 , wherein the side mold further comprises a covering portion extending downwardly from a lower end of the sloping portion, and at least one lamp recessing hole into which the lamp is inserted is formed in at least one of the covering portion and the sloping portion.

7. The backlight assembly of claim 6 , further comprising a bottom chassis receiving the side mold and having a socket insertion hole in a bottom surface of the bottom chassis,

wherein the lamp socket is inserted into the socket insertion hole so that the lamp connection portion and the light blocking plate are disposed above the bottom surface of the bottom chassis and the power connection portion is disposed below the bottom surface of the bottom chassis, and

wherein the lamp is inserted into the lamp connection portion and the power connection portion is connected to an inverter printed circuit board providing power to the lamp.

8. The backlight assembly of claim 7 , wherein a locking protrusion is formed on a rear surface of the light blocking plate and the locking protrusion is locked on the bottom chassis in a vicinity of the socket insertion hole.

9. A method of assembling a backlight assembly, the method comprising:

arranging lamp sockets;

inserting lamps into the arranged lamp sockets; and

combining the lamp sockets with at least one socket connection portion of a side mold to complete the assembling of the backlight assembly, wherein at least one portion of a bottom surface of the side mold is opened and the side mold has a supporting portion, a side wall formed at one side of the supporting portion, a sloping portion inclined downwardly at a side opposite to the supporting portion, and the at least one socket connection portion receiving the lamp socket,

wherein the lamp socket includes a lamp connection portion, a power connection portion, and a light blocking plate positioned at an interface between the lamp connection portion and the power connection portion,

wherein the lamp connection portion, the power connection portion, and the light blocking plate are integrally formed with each other as a single unitary indivisible unit, and

wherein the light blocking plate protrudes outward from the power connection portion.

10. A liquid crystal display comprising:

a liquid crystal display panel displaying an image signal; and

a backlight assembly providing the liquid crystal display panel with light, the backlight assembly including:

a lamp emitting light;

a lamp socket into which the lamp is inserted;

a side mold having at least one portion of a bottom surface thereof opened, the side mold comprising a supporting portion, a side wall formed at one side of the supporting portion, a sloping portion inclined downwardly at a side opposite to the supporting portion; and,

at least one socket connection portion receiving the lamp socket,

wherein the lamp socket includes a lamp connection portion, a power connection portion, and a light blocking plate positioned at an interface between the lamp connection portion and the power connection portion,

wherein the lamp connection portion, the power connection portion, and the light blocking plate are integrally formed with each other as a single unitary indivisible unit, and

wherein the light blocking plate protrudes outward from the power connection portion.

11. The liquid crystal display of claim 10 , wherein the at least one socket connection portion is formed integrally within the side mold.

12. The liquid crystal display of claim 10 , wherein the at least one socket connection portion is formed on a socket connection plate, and the socket connection plate is combined with the side mold.

13. A side mold having at least one portion of a bottom surface thereof opened and the side mold comprising:

a supporting portion;

a side wall formed at one side of the supporting portion;

a sloping portion inclined downwardly at a side opposite to the supporting portion; and

at least one socket connection portion receiving a lamp socket,

wherein the lamp socket includes a lamp connection portion, a power connection portion, and a light blocking plate positioned at an interface between the lamp connection portion and the power connection portion,

wherein the lamp connection portion, the power connection portion, and the light blocking plate are integrally formed with each other as a single unitary indivisible unit, and

wherein the light blocking plate protrudes outward from the power connection portion.

14. The side mold of claim 13 , wherein each of the at least one socket connection portion includes an internal surface of the side wall and a lateral surface of the sloping portion.

15. The side mold of claim 14 , wherein the lateral surface of the sloping portion included in the at least one socket connection portion comprises a locking protrusion or a locking hole engaging with the lamp socket.

16. The side mold of claim 14 , further comprising a covering portion extending downwardly from a lower end of the sloping portion, wherein at least one lamp recessing hole into which a lamp is inserted is formed in at least one of the covering portion and the sloping portion.
