Mold frame and liquid crystal display device using the same

1. A liquid crystal display comprising:

a liquid crystal display panel;

a driver integrated circuit (IC) configured to supply a driving signal to the liquid crystal display panel;

a printed circuit board configured to transmit the driving signal to the driver IC, wherein a recess is formed in the printed circuit board;

a backlight module formed below the liquid crystal display panel and configured to provide light to the liquid crystal display panel; and

a mold frame configured to receive the backlight module, wherein the mold frame comprises a single protruding portion which extends toward the liquid crystal display panel, wherein the protruding portion of the mold frame is configured to at least partially penetrate the recess of the printed circuit board, wherein the mold frame comprises first and second sides opposing each other, wherein the single protruding portion is integrally formed on the first side, wherein the single protruding portion has a thickness the same as that of the first side of the mold frame, and wherein the thickness is measured in a direction extending from the first side to the second side of the mold frame.

2. The liquid crystal display of claim 1 , wherein the mold frame comprises:

a plurality of supporting portions configured to receive and support a backlight module; and

an opening portion formed in the first side of the mold frame, wherein the opening portion is connected to at least two of the supporting portions.

3. The liquid crystal display of claim 2 , wherein the height of the protruding portion is substantially the same as the height of at least one of the supporting portions.

4. The liquid crystal display of claim 1 , wherein the recess includes a hole or a non-linear portion.

5. The liquid crystal display of claim 4 , wherein the non-linear portion has a curved shape.

6. The liquid crystal display of claim 4 , wherein the non-linear portion has a semi-circular shape.

7. The liquid crystal display of claim 2 , wherein the display further comprises a terminal portion interconnecting the driver IC and printed circuit board, wherein the terminal portion is not formed in the region which directly faces the recess of the printed circuit board.

8. The liquid crystal display of claim 2 , wherein the height of the protruding portion is greater than the height of the driver IC.

9. The liquid crystal display of claim 2 , wherein the printed circuit board is a flexible printed circuit (FPC).

10. A liquid crystal display comprising:

a liquid crystal display panel;

a backlight module formed below the liquid crystal display panel and configured to provide light to the liquid crystal display panel; and

a mold frame configured to receive the backlight module, wherein the mold frame has a plurality of sides comprising first and second sides opposing each other, wherein a first recess is formed in the first side, wherein a single protrusion is integrally formed on the first recess and extends toward the liquid crystal display panel, and wherein the width of the protrusion is significantly less than that of each of the sides,

wherein the single protrusion has a thickness the same as that of the first side of the mold frame, and wherein the thickness is measured in a direction extending from the first side to the second side of the mold frame.

11. The liquid crystal display of claim 10 , wherein the plurality of sides comprise third and fourth sides, and wherein three the second to fourth sides are non-recessed and have substantially the same height.

12. The liquid crystal display of claim 10 , wherein the plurality of sides comprise third and fourth sides longer than the first and second sides.

13. The liquid crystal display of claim 10 , wherein the height of the protrusion is substantially the same as the height of the sides where the protrusion is not formed.

14. The liquid crystal display of claim 10 , further comprising:

a printed circuit board configured to provide a driving signal to the liquid crystal display panel, wherein a second recess is formed in the printed circuit board, wherein the second recess is significantly less in size than the first recess, and wherein the protrusion of the mold frame is configured to at least partially penetrate the second recess of the printed circuit board.

15. The liquid crystal display of claim 14 , wherein the second recess includes a hole or a non-linear portion.

16. The liquid crystal display of claim 15 , wherein the non-linear portion has a curved shape.
