Abstract

A display device includes a container having a bottom plate, a light source disposed in the container, which provides light, a circuit board disposed in the container, a socket terminal electrically connected to the light source and the circuit board, and a display panel which receives the light from the light source and displays images. The circuit board and the light source are positioned on a same side of the bottom plate of the container. The socket terminal includes a socket part and a fixing part, the socket part and the fixing part are connected to the light source and circuit board, respectively.

Claims

1. A display device comprising:

a container comprising a bottom plate;

a light source disposed in the container, which provides light;

a circuit board disposed in the container, the circuit board and the light source are positioned on a same side of the bottom plate of the container;

a socket terminal electrically connected to the light source and the circuit board; and

a display panel which receives the light from the light source and displays images.

2. The display device of claim 1, wherein the circuit board is positioned perpendicular to the bottom plate of the container.

3. The display device of claim 2, further comprising a board holding part disposed in the container and holds the circuit board.

4. The display device of claim 1, wherein the socket terminal further comprises a fixing part connected to the circuit board.

5. The display device of claim 4, wherein the fixing part further comprises a housing having a space therein and a conductive first terminal, the conductive first terminal disposed in the space of the housing.

6. The display device of claim 5, wherein the circuit board further comprises a protruding edge and a contact terminal formed on the protruding edge of the circuit board, and

wherein the protruding edge is inserted into the space of the housing for the conductive first terminal to be connected with the contact terminal.

7. The display device of claim 4, wherein the fixing part is bent for hanging on an edge of the circuit board.

8. The display device of claim 4, wherein the fixing part comprises a contact portion recessed to be electrically connected to the contact terminal of the circuit board.

9. The display device of claim 1, wherein the socket terminal further comprises a socket part which holds the light source.

10. The display device of claim 9, wherein the socket part further comprises a pair of branches, and

wherein middle portions of the branches are bent to each other to form a holding portion and a guiding portion, the holding portion holds the light source, and the guiding portion guides the light source toward the holding portion.

11. The display device of claim 10, wherein a distance between the branches of the guiding portion is wider than a distance between the branches of the holding portion.

12. The display device of claim 10, the light source comprising an electrode which is inserted into the holding portion via the guiding portion, wherein the electrode of the light source is a lead wire.

13. The display device of claim 1, wherein the socket terminal is entirely conductive.

14. The display device of claim 1, wherein the socket terminal is directly connected to the light source and the circuit board.

15. The display device of claim 1, wherein the fixing part and the socket part are integrally formed.

16. A display device comprising:

a container comprising a bottom plate;

a light source disposed in the container, which provides light;

a circuit board disposed perpendicular to the bottom plate of the container;

a socket terminal electrically connected to the light source and the circuit board; and

a display panel which receives the light from the light source and displays images.

17. The display device of claim 16, wherein the circuit board and the light source are positioned at a same side of the bottom plate.

18. The display device of claim 16, wherein the socket terminal is directly connected to the light source and the circuit board.

19. A light supplying unit comprising:

a light source positioned in a linear direction;

a circuit board comprising a circuit which transfers power for driving the light source, the circuit board having a major plane; and

a socket terminal directly connected to the light source and the circuit board,

wherein the linear direction of the light source is perpendicular to the major plane of the circuit board.
