BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a computer having a liquid crystal display module, and more particularly, to a method of mounting a liquid crystal display module in a computer such as a notebook personal computer (hereinafter referred to as “NTPC”).
2. Description of the Related Art
Generally, a conventional NTPC is manufactured having a size that allows a user to exploit information in the course of his travels. In such an NTPC, a liquid crystal display (LCD) module is used as the display device for displaying the information. The liquid crystal display module has to be protected from being damaged when moving the computer system including the LCD module and a keyboard. Also, the LCD module has to be secured to a sash (or moveable frame) so it may be opened at time of use. To this end, the liquid crystal display module was provided at a bottom surface or an inner surface such that it overlapped with the keyboard installed on a top surface or an inner surface, or that it is opened for a user together with the keyboard, as the upper sash pivots with respect to one side of the lower sash.
FIG. 1 is a front view of a conventional notebook personal computer and FIG. 2 is a side view of the conventional notebook personal computer. Referring to FIGS. 1 and 2, in the conventional NTPC, a liquid crystal display module and an upper sash 12 are pivotally secured to a lower sash 10 by a hinge 20 as shown in FIG. 1. A protection rod 14a is defined in the edge of the liquid crystal display module 14, and a support piece 14b is defined in the protection rod 14a. This support piece 14b is secured to the bottom surface or inner surface of the upper sash 12 by means of screws 22, thereby supporting the liquid crystal display module 14 in such a manner that it is not removed.
Meanwhile, the hinge 20 pivotally couples an arm 18 with one end of a fixed rod 16. This fixed rod 16 is secured to the inner side, that is, to the rear wall of the lower sash 10 by means of the screws 22. The arm 18 is secured to the bottom surface or inner surface of the upper sash 12 by means of the screws 22, thereby supporting the liquid crystal display module 14 and the upper sash 12 in such a manner that they pivot with respect to the upper end of the rear wall of the upper sash 10. Further, an arm 16 is formed in the shape of an “F” such that it can sufficiently bear the load of the upper sash 12, that is, it makes good contact with the bottom surface of the upper sash 12.
In the conventional NTPC, as described above, the hinge 20 and the liquid crystal display module 14 are secured to the bottom surface of the upper sash 12 separately. This brings about a complication in the manufacturing process. Also, since the arm occupies a great area in the upper sash, the available area of the display portion, that is, the liquid crystal display module, becomes small. This increases the dimension of the NTPC.

FIG. 3 is a front section view of an NTPC employing a mounting apparatus for a liquid crystal display module according to an embodiment of the present invention, and FIG. 4 is a side section view of an NTPC employing a mounting apparatus for a liquid crystal display module according to an embodiment of the present invention.
Referring to FIGS. 3 and 4, the NTPC includes an upper sash 32 pivotally secured to a lower sash 30 by a hinge 40. This upper sash 32 is provided with a liquid crystal display module 34, and the edges or side walls of the liquid crystal display module 34, are provided with a protection rod 34a. The upper sash 32 has a rectangular plastic plate 32a, side walls 32b extending perpendicularly from the plastic plate 32a, a front wall not shown, and a rear wall 32c. Further, there is provided a blade 32d extending in parallel with the plastic plate 32a or extending with a slant toward the plastic plate 32a, in the upper ends of these walls, that is, the side walls 32b, front wall, and rear wall 32c. 
Meanwhile, the hinge 40 pivotally couples an arm 38 with one end of a fixed rod 36. This fixed rod 36 goes through a hole, not shown, defined from a middle position of the rear wall 32c of the uppers sash 32 to the end position of the blade 32d and a hole, not shown, defined from the rear side end of the upper plate of the lower sash 30, and then extends to the inner side of the lower sash 30. Further another side of the fixed rod 36 is secured to the inner face of the rear wall of the lower sash 30 by means of screws 42. The arm 38 is formed in such a manner that it extends from the hinge 40 by a length of the side face of the liquid crystal display module 34. The arm 38 also opposes the protection rod 34a and the side wall 32b of the upper sash 32. Thus, the arm 38 is secured by the screw 42 to be positioned between the protection rod 34a and the side wall 32b of the upper sash 32. At this time, the screw 42 passes through the side wall 32b of the upper sash 32 and the arm 38 and then reaches a middle position of the protection rod 34a, thereby coupling both of the liquid crystal display module 34 and the arm 38 with the upper sash 32. Accordingly, both of the upper sash 32 and the liquid crystal module 34 pivots with respect to the rear side edge of the lower sash 30 along with the arm 38.
