Abstract

A liquid crystal display module includes a backlight assembly, a liquid crystal panel on the backlight assembly, a printed circuit board under the backlight assembly, a top case covering a peripheral portion of the backlight assembly and a peripheral portion of the liquid crystal panel, a driving IC between the backlight assembly and the top case, and an insulating member between the top case and the driving IC.

Claims (24)

1. A liquid crystal display module, comprising:

a backlight assembly including a lamp along a direction;

a liquid crystal panel on the backlight assembly;

a printed circuit board under the backlight assembly;

a top case covering a peripheral portion of the backlight assembly and a peripheral portion of the liquid crystal panel;

driving ICs between the backlight assembly and the top case; and

an insulating member between the top case and the driving ICs such that the driving ICs are screened from the top case, wherein the insulating member includes a sidewall and a top wall connected to each other perpendicularly so that the insulating member has a “L”-like shape in its cross-section, a first side of the sidewall of the insulating member facing the driving ICs and a second side of the sidewall of the insulating member opposite to the first side facing the top case, wherein the sidewall includes a plurality of indentations and protrusions, wherein the plurality of indentations and protrusions alternate each other along the direction, so that an end of the sidewall of the insulating member has an indented shape and the sidewall of the insulating member has a square toothed shape, wherein one end of the top wall of the insulating member is interposed between the liquid crystal panel and the top case and contacts the liquid crystal and the top case.

2. The display module according to claim 1 , further comprising a connecting tab surrounding the peripheral portion of the backlight assembly, electrically connecting the printed circuit board to the driving ICs and electrically connecting the driving ICs to the liquid crystal panel.

3. The display module according to claim 2 , wherein the driving ICs are formed on an outer surface of the connecting tab along the sidewall of the backlight assembly.

4. The display module according to claim 3 , wherein the insulating member is adjacent to an inner surface of the top case.

5. The display module according to claim 4 , wherein the insulating member extends between the top case and the liquid crystal panel.

6. The display module according to claim 4 , further comprising a bottom case being coupled with the top case to hold the backlight assembly and the liquid crystal panel.

7. The display module according to claim 6 , where the insulating member extends between the top case and the bottom case.

8. The display module according to claim 1 , wherein the insulating member is adjacent to an inner surface of the top case.

9. The display module according to claim 8 , further comprising a bottom case being coupled with the top case to hold the backlight assembly and the liquid crystal panel.

10. The display module according to claim 9 , where the insulating member extends between the top case and the bottom case.

11. The display device according to claim 1 , wherein the insulating member includes a flexible sheet material.

12. The display module according to claim 11 , wherein the insulating member includes an insulating tape.

13. The display module according to claim 11 , wherein the insulating member has an adhesive property.

14. The display device according to claim 13 , wherein the insulating member is adhered to an inner surface of the top case.

15. The display module according to claim 1 , wherein the insulating member includes a plastic material.

16. The display module according to claim 1 , wherein the protrusions correspond to the driving ICs.

17. The liquid crystal display module according to claim 1 , further comprising a plurality of connectors, wherein the top case includes a plurality of connecting holes and the connectors are fastened on the insulating member through the connecting holes.

18. The display module according to claim 17 , wherein the connectors are fastened on the top wall of the insulating member.
