Abstract

A liquid crystal display module device includes a frame receiving a backlight assembly provided with optical sheets, a liquid crystal panel mounted onto the frame, a bottom case affixed to the frame, a top case enclosing edge portions of the liquid crystal panel and coupled to the bottom case, and a clip inserted into a first region of a coupled portion of the bottom case and the top case.

Claims (18)

1. A liquid crystal display module device, comprising:

a frame receiving a backlight assembly provided with optical sheets;

a liquid crystal panel mounted onto the frame;

a bottom case affixed to the frame;

a top case enclosing edge portions of the liquid crystal panel and coupled to the bottom case; and

a clip inserted into a first region of a coupled portion of the bottom case and the top case to constrain peripheral edge portions of the optical sheets between the liquid crystal panel and the backlight assembly, the peripheral edge portions include outermost portions of the optical sheets, an upper portion of the clip is in direct contact with the liquid crystal panel by penetrating through the top case.

2. The device according to claim 1 , wherein the clip has end portions that continuously presses against the liquid crystal panel to eliminate formation of a gap between the liquid crystal panel and the peripheral edge portions of the optical sheets.

3. The device according to claim 2 , wherein the first region has a plurality of mounting grooves upon which the end portions of the clip are mounted.

4. The device according to claim 3 , wherein a length of each of the mounting grooves is substantially the same as a length of the clip.

5. The device according to claim 3 , wherein a first one of the plurality of mount grooves is formed at a portion of the bottom case and a second one of the plurality of mounting grooves is formed at a portion of the top case.

6. The device according to claim 1 , wherein the clip has a U-shape including end portions formed approximately parallel to each other and a central portion between the end portions.

7. The device according to claim 6 , wherein the end portions continuously presses against the liquid crystal panel to eliminate formation of a gap between the liquid crystal panel and the peripheral edge portions of the optical sheets.

8. The device according to claim 7 , wherein the end portions provide an elastic force.

9. The device according to claim 7 , wherein a distance between the end portions is substantially the same as a distance between the top case and the bottom case.

10. The device according to claim 1 , wherein the clip and one of the top case and the bottom case are formed of the same material.

11. The device according to claim 1 , wherein the clip is positioned along the peripheral edge portions of the optical sheets adjacent to a lamp of the backlight assembly.

12. The device according to claim 1 , wherein the clip is positioned along a lengthwise direction of a lamp of the backlight assembly.

13. The device according to claim 12 , wherein the clip is positioned at a central region of the lamp along the lengthwise direction of the lamp.
