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 (17)

1. A display device, comprising:

a mold frame;

an inverter attached on the mold frame and having a first connector;

a display panel disposed on an upper surface of the mold frame;

a printed circuit board (PCB) having a second connector at an end thereof;

a flexible printed circuit (FPC) coupled between the display panel and the PCB,

wherein the first connector and the second connector are engaged for electrically connecting the inverter and the printed circuit board by bending the FPC to attach the PCB on a lower surface of the mold frame.

2. The display device of claim 1 , wherein:

the flexible printed circuit (FPC) has a driver integrated circuit (IC) disposed thereon; and,

the mold frame has a groove formed on a lower surface thereof in which the driver IC is received when the FPC is bent toward the lower surface of the mold frame.

3. 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.

4. The display device of claim 3 , wherein the mold frame comprises a lamp unit receiving portion integrally formed at an edge thereof for receiving the lamp unit.

5. The display device of claim 4 , wherein the lamp wire fixing unit is integrally formed in the lamp unit receiving portion.

6. The display device of claim 5 , wherein the lamp wire fixing unit comprises a plurality of fixing ribs.

7. The display device of claim 6 , wherein the fixing ribs are formed alternately at opposite edges of an end portion of the lamp unit receiving portion.
