The mounting method proposed in the above-mentioned US patents is called a side mounting method and the present invention is to further develop such a side mounting method, and the contents of the patent are also combined in the present specification.

5 shows an embodiment of the present invention. The bracket 10 (also referred to as a fixing unit) 10 has an "L" shape in cross section based on the main part or bottom part 13 and the bent part or vertical part 11 bent from the bottom part 13. (FIG. 5A). In addition, the upper surface portion 12 is preferably included. (FIG. 5B).

The height of the vertical portion 11 of the bracket 10 is similar to the thickness of the liquid crystal display module, and the mounting portion 21 and the fixing hole are disposed in the vertical portion 11 and the bottom portion 13. Each of the mounting holes 21 and the fixing holes 22 is spaced apart by a predetermined distance in the longitudinal direction of the bottom portion.

6 is a bracket of FIG. 5B on a lower support frame (also referred to as a main frame, a backing frame or a main support) 221 in a state before the upper support frame (also referred to as a top case, a front preventive paper frame or a top frame) is coupled. This is shown mounted.

5A, 5B and 6, the vertical portion 11 of the bracket 10 corresponds to the side of the lower support frame, the mounting hole 21 is the side and the support of the upper support frame not shown It is mounted side by side corresponding to the hole of (Supporting Body). The support is coupled to the body of the computer through the hinge mechanism and rotatably connected about the hinge axis and has a supporting surface parallel to the side of the module. For example, the rear case (Fig. 16) or the hinge arm, the hinge frame (Fig. 17). The fixing hole 22 of the bottom portion 13 of the bracket 10 corresponds to the bottom of the lower support frame 23 and serves to fix the bracket 10 to the lower support frame 221. When the bracket having the upper surface portion 12 is used as shown in FIG. 5B, the liquid crystal panel 212 may be fixed to the lower support frame 221 even before the upper support frame 224 of FIG. 7 is engaged.

The structure of the liquid crystal display module will be described in detail with reference to FIG. 7, which is a detailed exploded view of the liquid crystal display module to which the present invention is applied.

The liquid crystal display module 200 includes a light distribution device (also called a backlight unit) 210 having a light source 211 and a liquid crystal panel 212 having two substrates and a liquid crystal therebetween. The panel is supported by the lower support frame 221 and the upper support frame 224. Reflector plate 222a, light guide plate 222b, protective sheet 222c, first prism sheet 222d and second prism sheet 222e as a light distribution device on the lower support frame 221, which is usually made of plastic, for impact protection. The diffusion or protective sheet 222f and the liquid crystal panel 212 are sequentially stacked.

Also, a printed circuit board (PCB) (not shown), which is a driving circuit board, is electrically connected to the liquid crystal panel 212 through a tape automated bonding (TAB) or a tape carrier package (TCP) 215. When assembled, the driving circuit board is positioned on the rear surface of the lower support frame 221 by bending the TAB. Meanwhile, in order to reduce the weight of the module or prevent the module from being thickened due to the PCB, an opening O is formed in the lower support frame to locate the PCB.

The bracket 10 is fixed to the rear surface of the lower support frame 221 through the fixing hole 22 of the bottom portion. At this time, the vertical portion 11 of the bracket 10 is bent in the lateral direction of the lower support frame 221 so that the liquid crystal display device on the support surface of the support (rear case or hinge arm (frame)) through the mounting hole 21. The module will be mounted. The upper support frame 224 and the lower support frame 221 are coupled to surround the light distribution device 210, the through hole 225 formed on the side of the first mounting hole and the upper support frame 224 is one screw Aligned with each other to allow penetration. At this time, the vertical portion 11 may be located anywhere on the inner or outer side of the side wall of the upper support frame 224. Preferably, the vertical portion 11 is inserted inside the side wall of the upper support frame 224, that is, between the side surface of the lower support frame 221 and the side wall of the upper support frame to smooth the side of the entire module. do. That is, when the module is mounted on the hinge arm or the rear case, the order of penetration of the screws is a support hole formed on the support surface of the support (hinge arm or rear case), the through hole 225 of the upper support frame 224, and the mounting of the vertical part. Odd order. The screw is fixed to the mounting hole and the through hole at the time of mounting. If the lower support frame and the bracket are sufficiently firm, the through hole 225 of the upper support frame 224 has a U-shaped shape with the lower side open, and the upper support frame is separated and coupled even when the screw is coupled to the fixing hole of the bracket. This may be possible.

If the bracket is used as described above, the LCD module can be mounted without forming a mounting hole on the side of the lower support frame. Therefore, a thin module that is difficult to form a mounting hole directly on the side of the lower support frame 221 can also be installed. Can be mounted using the side. As a result, the bracket has an advantage that the side mounting method can be applied to the liquid crystal display module which is thinning without reducing the diameter of the screw.

Figure 8 is a perspective view of a fixing unit according to another embodiment of the present invention, to improve the bracket structure of the embodiment for applying to the side mounting method. In this embodiment, the fixing unit has a structure in which the brackets are fixed to the left and right sides of the lower support frame and the bottom portions of the brackets on both sides are extended to be connected to each other. The bracket of this structure is called a cover.

The cover 230 basically includes a main part, that is, a horizontal part 231 and a bent part, that is, a vertical part 232, and a fixing hole 230a is formed in the main part to be coupled with the lower support frame, and is vertical. In the part, a mounting hole 230b is formed on the support surface of the support, that is, the support surface of the rear case (Fig. 16) or the hinge arm (Fig. 17, 240).

The cross-section along the line A-A 'of the drawing shown in the present specification is based on the "L" shape, and the protrusion 233 is bent inward from the upper end of the vertical part so as to surround the liquid crystal panel. In addition, the vertical cover portion or the side wall 234 is bent along the side of the longitudinal direction of the cover 230, which serves to protect the lamp of the light distribution device or to protect the bent portion of the TAB. It may also be used to facilitate coupling with the upper support frame. This will be described in detail below.

The cover is formed to surround the lower support frame 221 along the longitudinal direction of the lamp, that is, the light source 211 of the light distribution apparatus 210 of FIG. 7, and the structure in which the cover 230 is mounted is shown in FIG. It is well shown in the perspective view. FIG. 9 is a view showing the display surface of the liquid crystal panel downward for easy understanding of the structure.

The cover 230 is mounted on the cover 230 and the lower support frame through a support hole (not shown) formed at the side edge of the lower support frame 221 and a fixing hole 230a formed at the side edge of the cover 230. 221). This is shown in FIG. 10, which is a partial view of the lower support frame 221 as viewed from the bottom direction, and the fixing hole 230a of the lower support frame formed at the side of the cover 230 in the lateral direction of the lower support frame 221. It is to be noted that the recess 221b through which the screw can be inserted is formed, and the mounting hole is not formed on the side of the lower support frame 221. This is to prevent the damage to the mounting hole forming portion due to the impact of the lower support frame 221 is weakened by forming a mounting hole in the side of the lower support frame in applying the side mounting method in the thin liquid crystal display module.

On the other hand, the cover 230 extends in the longitudinal direction of the lamp 211 to support the lower support frame 221, the first reason for applying the side mounting method by the jig (jig) in both sides of the liquid crystal display device module When the screw is mounted from the side by fixing, the center part of the module is to prevent the warpage from being generated by the side impact or its own weight. Therefore, the cover 230 is preferably made of steel (SUS). In addition, the bending of the lower support frame 221 occurs even in a combined state. When the lower support frame 221 made of plastic is bent by heat generation of the lamp of the light distribution apparatus, the upper support frame 221 is located on the upper side of the lower support frame 221. Wrinkle is generated in the light guide plate (222b of FIG. 7), which adversely affects the light distribution characteristics, and thus, in the present embodiment, this is prevented by adding a cover 230 for supporting the lower support frame 221. You can do it.

The cover 230 of the present invention may be mounted on the opposite side where the lamp 211 of the light distribution apparatus is installed, that is, on the PCB 216 side, which is shown in FIG. This configuration is also a structure for supporting the lower support frame 221, the effect is the same, it is natural that both may be applied, which will be described again with reference to FIG.

However, when only one place is to be mounted, as shown, the bracket structure 10 may be adopted on the other side, and the cover 230 may be installed on the lamp 211 side of the light distribution apparatus. This is because the light guide plate (sheet) of the light distribution device is not uniform in thickness, and is thin on the lamp side, so it is advantageous to install it on the lamp side to prevent wrinkles.

In FIG. 12, the cross section of the cover 230 is substantially “L” shaped, and the bracket form of FIG. 5A is taken as an example, and the fixing hole is coupled to the cover 230 and the lower support frame 221. 9 and 11 can be formed as an example. That is, the structure of the cover or the fixing unit according to the present invention is shown that can be changed in various ways.

Since both applications are applied, the lower support frame 221 has an advantage of preventing the deformation better, and the PCB 216 during the assembly operation by protecting not only the light distribution device but also the PCB 216 that is normally bonded with tape. ) Can be prevented from disconnecting the lower support frame 221, and by preventing the PCB is not lifted, it is possible to prevent the disconnection of the TAB.

FIG. 13 illustrates that the upper support frame 224 (also referred to as the top case or the top chassis), which is applied to the present invention, is mounted while the lower support frame 221 and the cover 230 of the LCD display module are coupled to each other. As illustrated, the coupled state is illustrated in the case of FIG. 12.

However, since the lower support frame 221 according to the present invention is wrapped by the cover 230, the cover 230 and the upper support frame 224 are actually coupled. As can be seen from the cross-sectional view of Figure 14, the coupling structure is an elastic protruding piece in place, preferably in the vertical cover portion 234, the cover 230 is made of a stainless steel (SUS) of the elastic material 230c is formed, and a coupling hole 224b is formed in the upper support frame 224 at the corresponding position. Alternatively, it is also possible to form the protruding piece in the upper support frame and the coupling hole in the cover. At this time, the vertical cover portion is pressed while abutting with the reflecting plate 235 to prevent the movement of the reflecting plate. Since the vertical cover portion 234 of the cover 230 is a metal that reflects light, and the protruding pieces occupy a small area, the vertical cover portion 234 may also serve as a reflector. That is, by removing the reflector 235 in FIG. 7 and properly disposing the vertical cover part, the cover can be provided at the same time as the reflector of the light distribution device.

Figure 15 shows the coupling structure of the cover, the upper support frame, the lower support frame in the PCB portion. In the liquid crystal panel having two substrates, one substrate protrudes from the other substrate, and thus a signal application pad 241 is formed. The drive signal output from the control integrated circuit (IC) on the PCB is applied to the pad via the drive chip on the TAB. The TAB is folded back to the light distribution device to reduce the non-display area of the display surface. At this time, since the main portion of the cover 230 presses the PCB, and the vertical cover 234 presses the TAB on the side surface to prevent rocking of the TAB or the PCB, it is possible to prevent a defect in the pad portion of the panel and the junction of the TAB.

After the upper support frame 224 corresponds to the module with the cover 230 is coupled as described above, when pushed downward, the elastic protrusion piece 232 is fitted into the coupling hole 224b of the upper support frame 224. It is temporarily coupled by loading, and is completely coupled by screwing through mounting of the through hole 224a of the upper support frame 224 and the cover 230 or the bracket. The lower support frame 221 corresponding to the mounting hole 230b and the through hole 224a has a recess 221b and does not form a separate mounting hole to prevent damage to the lower support frame 221. It is advantageous to

Of course, the combined liquid crystal display module and the case or the hinge arm are connected together, as shown in FIGS. 16 and 17, respectively.

The through hole 224a of the upper support frame 224 and the fixing hole 230a of the cover 230 are formed at positions corresponding to each other, and are coupled to the cover of the case by a screw 260. Of course, if the fixing hole 230a of the cover is sufficiently forced, the through hole may be separated after the screw is coupled to the mounting hole of the cover by making the U-shaped one side open.

In addition, in FIG. 17, the support arm 240a is also formed in the hinge arm 240 connected to the main body or the bracket connected to the hinge so that the screw 260 is simultaneously applied to the corresponding upper support frame 224, the cover 230, and the case 250. ) Since the portion connected to the hinge mechanism and substantially receiving the force is the hinge arm, only the support hole 240a and the mounting hole 224b of the force arm can be directly coupled. In this case, there may be no support hole 250a of the case.

FIG. 18 is a perspective view illustrating an example in which a liquid crystal display module having a cover structure according to the present invention is actually mounted on a portable computer. As shown in FIG. 2, it may be mounted on a case including both a front case and a rear case. In this example, only the rear case 250 is shown.

If only the rear case 250 is adopted, the display area of the liquid crystal display may be wider.

This structure will be described with reference to FIG. 19, which is a cross-sectional view taken along the line CC 'of FIG. As shown in FIG. 19, the liquid crystal panel 212 is fixed by a lower support frame 221, a cover 230, an upper support frame 224, a rear case 250, and a hinge arm 240 therebetween. . The fixing method is as described above.

In this case, the front case of FIG. 2 is omitted, and the front end of the rear case 250 and the front surface of the upper support frame 224 are positioned on the same plane.

As described above, the bending of the lower support frame is prevented due to the fixing unit, that is, the cover according to the present invention, and the side mounting method can be applied to the display module to be thinned regardless of the thickness of the lower support frame. .

That is, by forming an insert formed with a female thread in the lower support frame, or by forming a mounting hole on the side of the lower support frame to prevent the lower support frame is weakened and broken.

In addition, there is an effect capable of suppressing wrinkle formation of the light guide plate due to heat generation of the light distribution apparatus.

In addition, there is an advantage in maintaining a stable fixed position by preventing the PCB lift or tape breakage that may occur during the assembly (assemble) operation.

While various various modifications of the invention have been described above, these are merely examples and the invention is not limited thereto. That is, the cross-section is basically "L" shape, the horizontal portion, the main portion is coupled to the lower support frame, the vertical portion, the bent portion is coupled to the upper support frame structure, the mounting structure is not formed in the lower support frame Based on the various changes and modifications of the present invention will be possible.

However, it will be apparent from the appended claims that these various changes and modifications belong to the scope of the invention.
