At this time, the conductive film 11 and the PCB 12 connected to the first substrate 10a of the liquid crystal panel 10 are placed on the side of the guide panel. At this time, in order to prevent separation from the PCB 12 and the guide panel 20, a double-sided tape 15 is interposed between the PCB 12 and the guide panel 20 to adhere to each other.

The backlight unit may include a lamp array (not shown), a cover bottom 40 surrounding the bottom and the periphery of the lamp array, and uniformly spread the light emitted from the lamp array over the entire surface of the liquid crystal.

Hereinafter, an assembly process of a general liquid crystal display device will be described with reference to the drawings.

3A to 3D are process perspective views illustrating a method of assembling a general liquid crystal display module.

As shown in FIG. 3A, a general liquid crystal display module first prepares a liquid crystal panel 10 to which a board assembly including a conductive film 11 and a PCB 12 is connected. After preparing the guide panel 20 on which the backlight unit and the plurality of optical sheets are placed, the conductive film 11 and the PCB 12 come out to the side of the guide panel 20 as shown in FIG. The liquid crystal panel 10 is mounted on the guide panel 20 so as to be positioned on an upper surface of the panel 20.

Here, a cylindrical guide boss (20a) is formed on the side surface of the guide panel 20, PCB PCB 12a is formed in a position corresponding to the guide boss (20a) in the PCB 12 It is.

In the drawing, two PCBs 12 are shown, and a flexible printed circuit (FPC) connected to a signal connection between the PCBs 12 and a system board (not shown) formed on the rear surface of the cover bottom 40 ( 13) is formed.

In the drawing, the liquid crystal panel 10 is located on the lower side, and after the guide panel 20 is placed upward, the assembly process is shown, and the liquid crystal panel 10 is placed on the inner side of the guide panel 20. After completion, the liquid crystal panel 10 will be located relatively above the guide panel 20.

As shown in FIG. 3C, the length of the PCB 12 is limited to the side height of the guide panel 20. Like the A part, the conductive film 11 is folded to correspond to the side surface of the guide panel 20. When guided, the guide boss 20a is fitted into the PCB hole 12a. In addition, the portion B in Figure 3c is a view showing a state in which the PCB 12 is open, it is shown that the double-sided tape 15 is interposed on the guide panel 20. As described above, in the assembling process of the general liquid crystal display module, when the PCB 12 corresponds to the side surface of the guide panel 20, the guide boss 20a is further formed on the guide panel 20 as a structure. By interposing the tape 15 further, the separation of the PCB 12 from the side surface of the guide panel 20 is prevented.

However, when the double-sided tape 15 is attached, in the process of separating the liquid crystal display module assembled for the repair, peeling is difficult, and foreign matter may be generated by the adhesive material of the double-sided tape. In addition, when the conductive film 11 is folded to correspond the PCB 12 to the guide panel 20, the double-sided tape 15 may be attached to both sides of the conductive film 11 and the PCB 12. Pressing operation is required. In addition, the process of fitting the guide boss 20a into the PCB hole 12a in the process of making the PCB 12 correspond to the guide panel 20 is difficult, and therefore, the assembly process takes a long time. . When the operator's pressing operation is not performed properly, sound noise may occur between the speaker portion coupled to the module and the loose metal case in the completed liquid crystal display module.

If the pressing is not done properly, sound noise may occur on the system. That is, in the completed liquid crystal display module, sound noise may occur between the speaker portion coupled to the module and the loose metal case.

Second, when the PCB is mounted on the side of the guide panel when the double-sided tape is fixed at the same time as the alignment work with the boss formed on the guide panel, there is a high possibility of failure due to the PCB twist. In addition, there is a fear that bending of the conductive film causes an interference phenomenon between the mechanism and the drive IC.

Third, in the case of attaching the double-sided tape, in the process of separating the liquid crystal display module assembled for the repair, the peeling operation is difficult, and foreign matter may be generated by the adhesive material of the double-sided tape.

In order to prevent the PCB 120 from falling from the guide panel 160, a protrusion 165 is formed on an extension portion from the outer side of the guide panel 160 to the lower side (on the same surface as the bottom surface of the cover bottom). . In this case, the protrusion 165 is spaced apart from the outer portion of the guide panel 160 by a predetermined interval, and the PCB 120 is located in the space. In this case, the separation distance between the protrusion 165 and the outer portion of the guide panel 160 is the PCB 120 between the protrusion 165 and the guide panel 160 when assembled to the thickness of the PCB 120. Determine margin by enough margin to come in).

Meanwhile, in the drawing, the PCB 120 is in a state of being completely in contact with the guide panel 160, but it is not necessarily possible to be in a state of being in contact with it.

This may occur. In this case, the gap of the PCB 120 may be weakly moved up and down at the outer side of the guide panel 160, and the protrusion 165 may be located at the side, and thus, the left and right movement may be impossible.

It is dispersed to pass through the liquid crystal panel 100 side.

In addition, a case top 200 is formed to surround the upper edge and the sides of the liquid crystal panel 100 and the backlight unit.

It may be formed. At this time, if the thickness of the PCB 120 is about 1.0mm, the gap between the protrusion 165 in the side of the guide panel 160 is about the 'thickness of the PCB 120' or 'the Within the thickness of the PCB 120 + 0.1 ~ 0.2mm ', after entering the PCB 120 between the protrusion 165 and the PCB 120, it is not easily heard. In addition, in this case, the height of the protrusion 165 is 1.0 to 2.0 mm or more, so that the PCB 120 can act as a barrier that can not be passed over the protrusion 165, the thickness of the protrusion 165 Corresponds to or thicker than the thickness of the PCB 120.

The PCB 120 may be fixed to an outer side surface of the guide panel 160 by forming a size corresponding to the PCB 120 in a direction parallel to the PCB 120.

Meanwhile, a first elastic member 119a is formed at a portion of the case top 200 corresponding to the liquid crystal panel 100 to prevent friction due to contact, and the guide panel 160 and the liquid crystal panel 100 are formed. The second elastic member 119b is formed between the lower sides of the panel, and the third elastic member 119c is formed between the guide panel 160 and the third optical sheet 150c. Interruption of the elastic members 119a, 119b, and 119c prevents damage to the liquid crystal panel 100 and the optical sheet 150 due to impact at the site of contact with the mechanism or the guide panel 160.

The PCB 120 may be formed as one, but may be formed in plural when the area is large in some cases.
