ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a portable computer, and more particularly, to a portable computer with an LCD that can be rotated within 360 degrees.
2. Description of the Prior Art
A general portable computer comprises a machine body and an LCD connected to one end of the machine body in a rotatable manner. A keyboard is installed on the machine body as an input device and the LCD displays the images generated as a result of the various input signals.
Please refer to FIG.
1
and FIG.
2
. FIG.
1
and
FIG. 2
are diagrams of a portable computer
10
according to the prior art. The portable computer
10
comprises a machine body
12
that is approximately rectangular in shape, and an LCD
14
that is also approximately rectangular in shape connected to an end
16
of the machine body
12
. The LCD
14
can be folded onto the top face of the machine body
12
by a forward rotation (FIG.
1
), or it can be folded backwards 180 degrees to form a flat surface that is parallel to the machine body
12
(FIG.
2
).
Please refer to
FIG. 3
to FIG.
5
.
FIG. 3
to
FIG. 5
are diagrams of an alternative portable computer
20
according to the prior art. The portable computer
20
comprises an approximately rectangular machine body
22
, an LCD
24
that is also approximately rectangular in shape, and a connecting device
26
to connect together the machine body
22
and the LCD
24
. The connecting device
26
will permit the LCD
24
to be folded upon the top face of the machine body
22
by a forward rotation (FIG.
3
). The LCD
24
can also form a flat surface parallel to the machine body
22
by a 180 degree backward rotation (FIG.
4
). In addition, the connecting device
26
permits the LCD
24
to make an acute angle &thgr; with the bottom face
28
of the machine body
22
by a further backward rotation. However, neither of the prior art portable computers permits the LCD to be folded upon the bottom face of the machine body.
SUMMARY OF THE INVENTION
It is therefore a primary objective of the present invention to provide a portable computer with an LCD which can be rotated within 360 degrees to solve the above mentioned problem.
In a preferred embodiment, the present invention provides a portable computer comprising:
a machine body approximately rectangular in shape comprising a front end, a rear end, a top face and a bottom face;
a liquid crystal display approximately rectangular in shape comprising an upper end and a lower end; and
a connecting device comprising a front end and a rear end, the front end of the connecting device fixed to the rear end of the machine body in a rotatable manner, the rear end of the connecting device fixed to the lower end of the liquid crystal display;
wherein the connecting device enables the liquid crystal display to be folded upon the top face of the machine body by a forward rotation or upon the bottom face of the machine body by a backward rotation.
It is an advantage of the present invention that, with the connecting device, the liquid crystal display can not only be folded upon the top face of the machine body, but can also be folded upon the bottom face of the machine body.
This and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after having read the following detailed description of the preferred embodiment which is illustrated in the various figures and drawings.
