And forming a vertical portion; and fixing the hinge arm to a vertical portion of the support frame.

According to another feature of the invention, a hinge having a hinge arm, the hinge arm is inserted into the hinge mount and rotated and extending in the rotational axis direction of the hinge mount; and has a support frame on the edge, the support frame is A flat panel display having a vertical portion extending in the hinge arm direction and a horizontal portion extending from the vertical portion toward the hinge mount, wherein the horizontal portion is coupled to the hinge arm; Provided is a portable computer including a body coupled to the flat display device and the hinge.

As the flat panel display device which can be applied to the present invention, there are PDP and FED, and a liquid crystal display device is preferable.

Preferably, the present invention further includes a case for protecting the flat panel display.

In the present invention, preferably, the case includes a front case and a rear case coupled to the front case.

The combination method of the portable computer and the flat panel display device according to the present invention can maximize the display area because there is no hinge arm extending parallel to the liquid crystal display device.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

3 is a partial plan view showing a state in which the liquid crystal display device 30 is coupled to the case 20 by the method of an embodiment according to the present invention in the case 20 hinged to the main body 10.

In the drawing, the support frame 31 supporting the liquid crystal panel and the light distribution device (not shown) extends downward, and the extension arm 31a of the support frame is mounted to the hinge mount 41 to rotate. Combined with In the present specification, the lower part means a lower part, that is, a hinge arm in the drawing.

That is, the present embodiment has a difference in that the vertical portion of the hinge arm applied in the hinge coupling of the conventional portable computer does not have an extension portion 31a of the support frame 31 instead.

The extension part 31a of the support frame 31 may be manufactured by casting or pressing, and the extension part 31a may include a through hole 33 or a screw hole to which a horizontal hinge arm 40 may be coupled. Is formed. Figure 4 is a schematic perspective view showing the shape of the hinge arm for fastening the extension of the support frame of the embodiment of Figure 3 and the shape of the coupling hole of the support frame.

As shown, the hinge arm 40 is mounted to the hinge mount 41, the rotating portion 40a is a pin shape having a circular cross section, the portion 40b coupled to the extension of the support frame has an angular cross section. As an example, the figure shows a rectangle. In this embodiment, since the support frame 31 is coupled to the hinge arm 40 of a rectangular shape, the support frame 31 can be prevented from slipping even when it is simply inserted and coupled.

5 is a schematic perspective view showing another embodiment of the support frame 31 according to the present invention, wherein the extension portion 31a of the support frame further includes a horizontal portion 31b having an end bent inwardly. Doing.

That is, in the embodiments of FIGS. 3 and 4, the hinge arm is coupled to the extension part of the support frame side by side, whereas this embodiment forms a horizontal part 31b at the end of the extension part and the hinge arm 40. ) Are combined from the front.

At this time, the coupling between the hinge arm 40 and the extended horizontal portion 31b of the support frame 31 may be performed through the screw 50. Of course, it can also be fixed with a pin.

This embodiment can be applied in a situation where it is difficult to form a wide width of only the extension portion like the first embodiment because the width t of the support frame is usually narrow.

That is, in the first embodiment, since the width of the extension portion coupled with the hinge arm is too narrow, the coupling force with the hinge arm may be weakened, so it is preferable to form the horizontal extension portion and engage the hinge arm from the front.

Of course, although not shown, it is also possible to combine from the rear.

FIG. 6 illustrates that the hinge arm is coupled to the lower side of the horizontal extension unit by the modification of FIG. 5. In the situation where the thickness of the portable computer as a whole may increase as in the case of FIG. 5, the lower side of the horizontal extension unit 31b is shown. It is preferable to combine.

FIG. 7 is a variation of FIG. 6, which is a combination of the bottom coupling of FIG. 6 and the coupling in the lateral direction of the extension adopted in the first embodiment in order to increase the coupling force with the hinge arm, and is applied to increase the coupling force.

5 to 7 may be formed integrally with the support frame as in the first embodiment, it is also possible to use a horizontal bracket of course.

8 is a schematic exploded perspective view of a portable computer according to the present invention. In the case of the first and second embodiments of the present invention, the hinge arm and the support frame are coupled to the liquid crystal display device 30 itself. Since the hinge is coupled to and receives a force, the case is divided into a rear case 20 and a front case, and serves to protect the liquid crystal display device 30 by combining the front case 21 and the rear case 20. Since it is not mechanically coupled to the liquid crystal display device, it is preferable to adopt a shock absorbing material with a material such as sponge or rubber on the back side of the liquid crystal display device 30.

It is also possible to attach to the back surface of the liquid crystal display device or the inner surface of the rear case with a sticky material that can be easily attached and detached in place of the mechanical coupling between the liquid crystal display device and the case. An example of this is posthumous.

According to the method of fixing the computer and the image display device according to the present invention as described above, in the use of a conventional long extending hinge arm (long arm) by engaging the hinge arm formed only in the lateral direction by extending the support frame Since the side non-display area of the generated image display panel can be minimized, the ratio of the image display area is increased.

On the other hand, the embodiments of the present invention described above are merely illustrative, it will be appreciated by those skilled in the art that various changes and modifications may be made without departing from the spirit of the present invention. For example, various other flat panel displays may be used in place of the liquid crystal display, and the vertical extension portion of the support frame and the hinge arm may be variously combined with screws, and grooves having various shapes in addition to the squares disclosed in the groove coupling may be used. It may be formed in the vertical extension of this support frame.

In addition, the hinge mount of the hinge may be fixed to the body or to the case.

However, it will be apparent from the scope of the appended claims that all such changes and modifications fall within the scope of the present invention.
