Abstract

Disclosed is a mold frame structure of an LCD including a main frame, a plurality of connection plate coupling parts corresponding to PCBs attached to the rear side of the main frame, wherein the connection plate coupling parts are integral to the main frame along edges of the main frame, and a plurality of ground connection plates coupled to the plurality of connection plate coupling parts, for grounding ground terminals of the PCBs to the upper case.

Claims (37)

1. An LCD mold frame assembly comprising:

a main frame

a plurality of connection plate coupling parts corresponding to PCBs attached to the rear side of the main frame, wherein the connection plate coupling parts are integral to the main frame along edges of the main frame; and

a plurality of ground connection plates coupled to the plurality of connection plate coupling parts, for grounding ground terminals of the PCBs to an upper case.

2. The mold frame assembly according to claim 1 , wherein the ground connection plate includes a coupling hole formed thereon and to which a screw is coupled.

3. The mold frame assembly according to claim 2 , wherein the coupling hole of the ground connection plate is elongated.

4. The mold frame assembly according to claim 1 , further comprising:

a display panel;

a panel guide coupled with the main frame;

a top case coupled with the main frame so as to protect the display panel; and

a backlight unit;

wherein a display panel and a backlight unit are stacked on the main frame.

5. The mold frame assembly according to claim 4 , wherein the ground connection plate has a case ground portion formed at an edge thereof and is grounded to the top case.

6. The mold frame assembly according to claim 1 , wherein the ground connection plate has two coupling holes, one having a circular shape and the other having a groove shape with an open portion on one side.

7. The mold frame assembly according to claim 1 , wherein the ground connection plate has a latch jaw.

8. The mold frame assembly according to claim 1 , wherein the connection plate coupling part has at least one coupling groove.

9. The mold frame assembly according to claim 1 wherein the PCBs have ground terminals that are grounded to the ground connection plate by a screw.

10. The mold frame assembly according to claim 9 , wherein the ground terminals of the PCBs, the ground connection plates, and the top case are electrically connected by a screw.

11. The mold frame assembly according to claim 1 , wherein the ground connection plate has connection plate coupling part coupled to the top case.

12. An LCD display comprising:

a display panel;

a mold frame assembly comprising:

a main frame

a plurality of connection plate coupling parts corresponding to PCBs attached to the rear side of the main frame, wherein the connection plate coupling parts are integral to the main frame along edges of the main frame; and

a plurality of ground connection plates coupled to the plurality of connection plate coupling parts, for grounding ground terminals of the PCBs to an upper case;

a backlight unit stacked with the display panel in the main frame;

a panel guide frame coupled with the main frame; and

a top case coupled with the main frame.

13. The LCD display according to claim 12 , wherein the ground connection plate includes a coupling hole formed thereon and to which a screw is coupled.

14. The LCD display according to claim 13 , wherein the coupling hole of the ground connection plate is elongated.

15. The LCD display according to claim 13 , wherein the ground connection plate has a case ground portion formed at an edge thereof and is grounded to the top case.

16. The LCD display according to claim 12 , wherein the ground connection plate has two coupling holes, one having a circular shape and the other having a groove shape with an open portion on one side.

17. The LCD display according to claim 12 , wherein the ground connection plate has a latch jaw.

18. The LCD display according to claim 12 , wherein the connection plate coupling part has at least one coupling groove.

19. The LCD display according to claim 12 , wherein the PCBs have ground terminals that are grounded to the ground connection plate by a screw.

20. The mold frame assembly according to claim 19 , wherein the ground terminals of the PCBs, the ground connection plates, and the top case are electrically connected by a screw.

21. The mold frame assembly according to claim 12 , wherein the ground connection plate has connection plate coupling part coupled to the top case.
