The present invention relates to a fixed structure of a liquid crystal module in a notebook model, more specifically in accordance with the trend of the slimmer of the notebook using a conventional screw (screw), etc. It relates to deforming to a fixed structure without using screws.

In general, a liquid crystal display device includes a liquid crystal module, a driving circuit unit for driving the liquid crystal module, and a case surrounding the outer portion of the liquid crystal module. Among them, the liquid crystal module includes a liquid crystal panel in which liquid crystal cells are arranged in a matrix form between two glass substrates, and a backlight device for irradiating light to the liquid crystal panel. In order to complement the characteristics of the light, the light sheets are arranged and stacked.

The liquid crystal panel, the backlight device, and the light sheets must be fastened in an integrated form to prevent light loss, and must be protected from damage from external shocks. To this end, a case for a liquid crystal display device formed to surround a backlight device and an optical sheet including an edge of the liquid crystal panel is provided. As such, the liquid crystal display device is mounted to a portable information processing system such as a portable computer such as a notebook computer and used as a display device.

1 shows the appearance of a notebook computer. As can be seen in the figure, the configuration is largely divided into a main body 10 in which the information processing system is configured and a display unit 20 for displaying an image, of which the display unit 20 is hinged. It is fastened to the main body 10 as a case 22 connected through the back and a kind of liquid crystal display device 24 fixed to the case 22.

FIG. 2 is a perspective view illustrating an exploded view of only the display unit 20 of the notebook computer as shown in FIG. 1 in order to see a structure of a hinge fixing the liquid crystal module 24 inside the case 22. Looking at the configuration, the liquid crystal module 24 into the front case of the plastic material covering the front of the liquid crystal module 24, and the rear case (rear case) covering the rear of the liquid crystal module 24. There is an elongated metal bar, that is, a hinge arm 40 formed in a predetermined pattern to catch its flow on the side of the end of the hinge arm 40, and at the end of the hinge arm 40 is connected to the main body. The hinge 42 for this is comprised.

FIG. 3 shows how the liquid crystal module 24 and the hinge arm 40 accommodated in the rear case shown in FIG. 2 are substantially fastened. In other words, holes are formed on the two hinge arms 40 located at both sides thereof, thereby fastening screws and the like. In this case, the ordinary screw penetrates through the upper cover 30 of the liquid crystal module 24 made of aluminum to reach the main support (not shown) therein.

As such, a side mounting method in which the liquid crystal module is fixed at the side of the portable information processing system by a fastening means such as a screw groove formed on the side of the display has been preferred for slimming the device. Recently, however, as a backlight device using a light emitting diode (LED) as a light source is increasingly considered, there are many limitations in using the M2 standard screw in a product having a total thickness of 2 to 3 mm.

On the other hand, due to this problem, the front mounting method of fastening the screw on the front of the liquid crystal module has risen again. This is because the area other than the effective display area for realizing the image is rather large, so that unnecessary space in the system is increased. This causes a disadvantage that the narrow side of the screen, that is, the bezel (bezel) can not be taken narrowly. In addition, the problem of work time due to the fastening of the screw and the fastening of the screw caused by the fastening process of the screw and the liquid crystal module is generated.

Accordingly, an object of the present invention is to improve the above problems caused by conventional screw fastening by further extending the conventional hinge structure which is fastened only to the side of the liquid crystal module to the upper and lower surfaces.

And the achievement of this object can be further embodied by the present invention. That is, the configuration of the notebook computer having a fixed structure of the liquid crystal module includes: a main body including an information input device and an information processing device; A liquid crystal module for implementing an image; A hinge arm having a module insertion groove of a 'C' shape fastened to a side of the liquid crystal module; A hinge fastened to an end of the hinge arm and fastened to the main body; A rear case accommodating the lower surface of the liquid crystal module which has the hinge arm and the hinge and received therein; And a front case fastened from the front of the rear case.

First, before describing the above configuration in detail, the external configuration of the notebook computer according to the present invention will be briefly described. Although not shown in a separate drawing, it is largely divided into a main body that forms an information processing system therein and a display unit that implements information from the main body in an image, among which the display unit will be described in more detail later. It is fastened to the main body through the hinge etc. which were comprised in.

Above all, in the present invention, the above display unit is referred to as a liquid crystal display device. This is a concept of light and constitutes a liquid crystal panel in which liquid crystal cells are arranged in a matrix form between two glass substrates, and a backlight device for irradiating light to the liquid crystal panel. The LCD module includes a liquid crystal module in which optical sheets are arranged to be complemented, a driving circuit unit for driving the liquid crystal module, and a front case and a rear case made of a plastic material surrounding the liquid crystal module. .

4 shows a liquid crystal module 124 and a liquid crystal module 124, which are housed inside a rear case made of a plastic material which surrounds an outer portion of the center, and prevent the liquid crystal module 124 from flowing inside the rear case. The hinge arm 140 includes a hole for fastening a hinge or the like at the end thereof to be fastened to the hinge arm 140. Here, the hinge arm 140 is fastened to the left and right sides of the liquid crystal module 124, and the 'c' shaped module insertion groove 140a is formed to surround the side surface of the liquid crystal module 124. The lower end is formed with a hole 140b for fastening a hinge (not shown) used for fastening with the notebook body.

In addition, the length L and the width W of the module insertion groove 140a will be described below. The formation length L of the module insertion groove 140a is equal to the length of the left and right outer sides of the liquid crystal module 124 as shown in the drawing. In other words, it should be designed considering the thicknesses of the upper and lower covers (not shown) covering the outer portion of the liquid crystal panel 124. In addition, the width W is required to be manufactured in an appropriate length in order to withstand the impact from the outside. For example, assuming that the width of the cover covering the outer portion of the liquid crystal panel 124 is 1 cm, It is preferable that the margin is approximately 0.7 to 0.8 cm, but it is not necessarily limited thereto.

In addition, in relation to the method of fastening the hinge arm 140 to the liquid crystal module 124, when the hinge arm 140 is made of a metal material such as aluminum (Al) or iron (Fe), the liquid crystal module 124 Assume that the way of pushing from the bottom of may be more appropriate. On the other hand, however, it can not be excluded that the hinge arm 140 may be made of a material such as plastic. Therefore, because of the elasticity of the nature of such a material in this case can be used to fasten directly from the left and right side, similar to the form of the tip rather than the push type from the bottom.

FIG. 5: shows the right side view along the cutting line A-A` of FIG. The width W of the hinge arm 140 in which the module insertion groove 140a is formed is the same as the width W of FIG. 4, and the height h will be briefly described. In recent years, the total thickness of notebooks is becoming thinner and thinner due to the introduction of LED backlights. From this point of view, the total thickness of the product has been possible up to about 2 to 3 mm, and the hinge arm 140 fastened to the left and right sides, as mentioned above, covers the outer cover of the liquid crystal panel 124. Considering the above, it is expected to slightly exceed the above figures.

6 includes a hinge 142 at the end of the hinge arm 140 and is fastened to the liquid crystal module 124 to be stored in the rear case 126. After the storage is completed, the front case 122 is fastened thereon to complete the display unit of the notebook, that is, the liquid crystal display device.

However, what has been described so far is only one preferred embodiment and may be modified accordingly. For example, assuming a hinge arm 150 made of a plastic material and having a module insertion groove 150a formed therein as shown in FIG. 7, an opposite side to which a hinge (not shown) is fastened through the hole 150b. At the end may be formed to extend the shape according to the invention. In this case, the hinge arm 150 having the module insertion groove 150a additionally covers a portion of the upper edge from the left and right sides 124a of the liquid crystal module 124. The fastening method may be a fastening method of directly inserting the left and right side surfaces 124a of the liquid crystal module 124 into the module insertion groove 150a of the hinge arm 150 in the form of a tick. . At this time, the left and right side surfaces 124a of the liquid crystal module 124 and the upper and lower side surfaces 124b and 124c which are in contact with the left and right side surfaces 124a are also the modules of the hinge arm 150. It is fitted in the insertion groove 150a.

In addition, although not shown in a separate drawing, if you add the description with reference to Figure 4 by dividing the length (L) of the hinge arm 140 in three parts of the opposite end where the hole 140b is formed in the present invention only It can be applied, and on the other hand, the present invention can be applied to both sides except the middle L / 3 region. In addition, when the length L of the hinge arm 140 is divided into two, the present invention can be applied only to the L / 2 region of the opposite end where the hole 140b is formed, and of course, the opposite case can be established. In the hinge arm 140 that is fastened as a cover surrounding the liquid crystal module 124, the scope of the present invention may be provided.

As a result of the above configuration, it is possible to improve the problems caused by the improper fastening of the liquid crystal module and the screw, etc. caused in the assembling process, and to realize the liquid crystal module of the thin model.
