Abstract

A display module of an LCD device having a rear case shaped as a four-cornered container having sidewalls on each of its four edges; a backlight assembly formed by depositing and fixing a reflector plate, a light guide plate, and a series of sheets onto a mold frame where a lamp assembly receiving portion, a gate PCB receiving portion, and a source PCB receiving portion are integrally formed; an LCD panel module having an upper panel, a lower panel coupled to the upper panel with a liquid crystal inserted therebetween, a gate PCB electrically connected to an end portion of the lower panel, and a source PCB electrically connected to another end portion of the lower panel and has a conductive pattern for an electric signal to be applied to an inverter; a main chassis which defines an active screen area of the LCD panel module and couples the mold frame and the LCD panel module to the rear case; and a front case coupled to the main chassis and covering a whole surface of the LCD panel module excluding the active screen area.

Claims

1. A display device comprising:

a main chassis;

a mold frame coupled with the main chassis, the mold frame having a plurality of protrusions at a side thereof; and

a display module disposed between the main chassis and the mold frame, the display module including a display panel and a plurality of flexible printed circuits (FPCs) attached to the display panel, wherein the FPCs bend around the side of the mold frame at which the protrusions are formed, and

wherein the protrusions protrude between the FPCs to spatially separate the FPCs from each other, and each of the protrusions contacts with the main chassis.

2. The display device of claim 1, wherein the protrusions protrude toward the main chassis.

3. The display device of claim 1, wherein each of the flexible printed circuits (FPCs) has a driver integrated circuit disposed thereon, and

wherein the mold frame further has a groove formed at a surface thereof, and the driver integrated circuit is received in the groove when the FPCs bend around the side of the mold frame.

4. The display device of claim 1, further comprising:

a lamp unit received in the mold frame and having a lamp wire connected thereto; and

a fixing unit for fixing the lamp wire to the mold frame.

5. The display device of claim 4, wherein the mold frame further has a lamp unit receiving portion integrally formed at an edge thereof for receiving the lamp unit.

6. The display device of claim 5, wherein the lamp wire fixing unit is integrally formed in the lamp unit receiving portion.

7. The display device of claim 6, wherein the lamp wire fixing unit includes a plurality of fixing ribs.

8. The display device of claim 7, wherein the fixing ribs are formed alternately at opposite edges of an end portion of the lamp unit receiving portion.
