In the present invention, although the PDP, FED, etc. can be applied as the flat panel display device, the liquid crystal display device is preferable.

The fixing method of the portable computer and the liquid crystal display device according to the present invention adopts a method and a structure of fixing by a support, so that no separate coupling means is required.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. For convenience of description, a liquid crystal display device will be described as an example of a portable computer and a flat panel display device thereof.

3 is a plan view illustrating a state in which a liquid crystal display device is installed in a case 24 having a fixing frame or a support (hereinafter, referred to as a support) according to an embodiment of the present invention.

The case has a fixing protrusion 31 which is a support body around each corner, and the position and arrangement of the fixing protrusion 31 are considered in consideration of the size of the liquid crystal display device 40 including the support frame. Select the position, that is, the distance from the edge, the distance from each side, etc. so that 40) can be forcedly fitted.

In the case of the plastic case 24, the fixing protrusions 31 may be integrally formed by, for example, an injection process. Of course, the case of the metal material can be formed integrally with the case and the fixing projections. In this case, the protrusion may be inserted by drilling a predetermined position of the case by a work process such as punching.

In addition, the height of the projection is determined in consideration of the thickness of the liquid crystal display device.

On the other hand, in order to prevent the liquid crystal display device 40 from colliding with the projections, an elastic body such as resin may be coated on the projections.

4 is an example in which the fixing protrusions are arranged differently according to the edges, it is preferable to install the fixing protrusions 31 at each corner position for stable fixing, but the material or shape of the protrusions 31, or the arranged position Since the fixing force may vary depending on the case, sufficient fixing force may be secured by selecting two corner portions as shown in FIG. 4, and the positions of the protrusions may be alternately installed at the upper and lower portions of the case.

5 is configured such that the fixing projection 38 can cover the display portion of the liquid crystal display device 40 to a certain extent in the shape of a bracket. At this time, the bracket 38 is provided so that only one of the upper part and the lower part of the case, or the left and right sides is installed, and the mounting is easy.

6, 7 and 8 illustrate that the fixing protrusion may have a different shape.

3 and 4, the shape of the protrusion may have a simple cramp shape, and as shown in FIG. 6, two protrusions 32 of a circular cross section may be provided at each corner.

Since the projections 32 shown in FIG. 6 each have a small cross-sectional area, an elastic force may be increased to increase the fixing force.

In FIG. 7, the height of the corner portion of the cramped protrusion 33 is increased, and the width of both ends is formed to be small, and the streamlined shape is overall. The protrusion 33 is manufactured in a streamline shape as a whole, so that there is no part to generate stress concentration outside, and the edge portion 33a is larger, which is advantageous for maintaining strength. In addition, it is possible to increase the elastic force to improve the fixing force by forming a smaller width of both ends (33b).

FIG. 8 shows a cross-shaped protrusion 34, which is smaller in width than the protrusion of FIG. 3, but has many portions supporting the protrusion 34 in a cross shape rather than at right angles. Since the protrusion 34 is small in width, the elastic force is increased to improve the fixing force, and the support of the overall protrusion can be sufficient.

9 and 10 illustrate that the protrusions 31 may be arranged in various directions. In FIG. 9, the protrusions 35a may be provided on each side of the liquid crystal in addition to the protrusions 35 installed at each corner. It is shown that the display device 40 can be fixed stably, and some sides can be omitted.

In FIG. 10, the protrusion 35a is formed to support the side of the liquid crystal display. As in this example, when forming the projection 35a only on the side portion, for example, the fixing rib 36 to fix the front case (see 122 of FIG. 2) coupled to the rear case 24 at the corner portion. Or it can be applied when the projection is located. At this time, the projection 35a may be slightly longer than the length disposed in the corner portion.

11 shows that the protrusions 37 may be formed in a shape that is supported by each corner portion of the case, and the protrusions 37 are supported by the edges, so that the protrusions 37 are supported in the lateral direction. There is an advantage to consider less. In addition, it is also possible to fix the liquid crystal display device 40 by adopting only one by increasing the shape of the projection depending on the situation.

Fig. 12 is a rear view of the liquid crystal display device showing the second embodiment of the method of combining the liquid crystal display device according to the present invention, in which the groove 41 is formed on the rear surface of the liquid crystal display device and the shape corresponding to the case. The present invention relates to a method of forcibly fitting and forming a projection 31 and a structure thereof.

As shown, the groove 41 is formed so that the projection can be fitted to the rear surface of the frame supporting the liquid crystal display device 40, the groove shape may be a circular groove 42 as shown in FIG. , It has a shape so as to correspond only to the shape of the projection.

Meanwhile, the groove 41 may be formed on the inner surface of the case, and may have a protrusion corresponding to the groove on the rear surface of the liquid crystal display device 40.

On the other hand, the shape and arrangement of the projections inserted into the grooves provided in the liquid crystal display or the case can be applied as shown in Figures 3 to 11 as it is, and molded integrally with a plastic material such as the case or a case with a separate elastic material It can be fixed by forming a projection on it.

In the first and second embodiments, the rear case and the liquid crystal display are in the form of a forced fit or just a combination, but when the fixing force is a concern, the front case (see 122 of FIG. 2) not shown is fixed by combining the rear case with the rear case. Can improve.

On the other hand, Figure 14 is a plan view showing a state in which the hinge arm is coupled to the case when the display unit is coupled to the main body, the hinge coupling is made through the hinge mount 51 and the hinge arm 52, in the figure the hinge arm It is shown that the long 52 is coupled to the side of the case 24. Here, although the protrusion 61 or the fastener is formed in the hinge arm 52 and the groove is formed in the case 24, the embodiment which changed both can bring about the same effect.

In addition, as shown in FIG. 15, the arm 70 may be ejected at the same time when the case 24 is ejected.
