ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a personal computer having a plurality of display panels, and more particularly to a display apparatus or a display unit having a plurality of display panels.
It is a recent trend that a plurality of images are displayed simultaneously on a display panel of a personal computer. Nowadays, a personal computer having a plurality of display panels is proposed so that utility of a user of a personal computer is improved. An example of such a personal computer having a plurality of display panels is disclosed, as a first prior art, in unexamined Japanese Patent Publication Hei01-234927, namely 234927/1989. In the example disclosed therein, a plurality of monitors and connectors are provided in a personal computer with those monitors and connectors being separated with each other. Another example of such a personal computer having a plurality of display panels is disclosed, as a second prior art, in unexamined Japanese Patent Publication Hei04-246721, namely 246721/1992. In also the another example disclosed therein, another display monitors are added to an original display monitor with the original and the another display monitors being separated with each other. Still another example of a television and a personal computer each having a plurality of display panels are disclosed, as a third prior art, in unexamined Japanese Patent Publication Hei09-200648, namely 200648/1997. In also the still another example disclosed therein, a plurality of video display panels each consisting of a cathode ray tube (CRT) or liquid crystal are combined to a personal computer. However, video display panels, floppy disk drives, connectors, or the like are located in a plurality of directions, respectively.
However, when a plurality of display apparatus are used in a personal computer, a large space is inconveniently required for location of such a plurality of display apparatus.
In the above-mentioned first, second and third prior arts, in order to see a plurality of images by a personal computer, a plurality of images are displayed in divided areas of a single display panel, respectively. Otherwise, a plurality of images are displayed in a single display panel with the images being overlapped on each other and a desirable image is seen by setting the desirable image in the forefront. However, when a plurality of images are displayed in divided areas of a single display panel, it is inevitably caused to occur that each image is too small to be seen comfortably. As a result, an efficiency of a job by the use of the personal computer becomes worse. On the other hand, when a plurality of images are displayed in a single display panel with the images being overlapped on each other, it is, of course, impossible to see a plurality of images simultaneously.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a compact personal computer which has a plurality of display panels.
It is another object of the present invention to provide a display apparatus for use in a personal computer, which has a plurality of display panels.
Other objects of this invention will become clear as the description proceeds.
According to an aspect of the present invention, there is provided a personal computer which displays a plurality of images, comprising: a body of the personal computer; a primary display panel provided on a front side of the body; and at least one secondary display panel which is provided adjacently to the primary display panel.
The primary display panel may have a space between a display surface and a back surface thereof, the secondary display panel being slid to be contained into the space.
A rack may be integrally provided on the secondary display panel while a pinion may be provided on the primary display panel, the rack and the pinion being adjusted to be operable as rack and pinion mechanism, the secondary display panel being slid to be contained into the space by the use of the rack and pinion mechanism.
The primary display panel may have a display surface thereof, the secondary display panel being slid to be contained in a front side of the display surface.
The primary display panel may have a back surface thereof, the secondary display panel being slid to be contained in a rear side of the back surface.
The secondary display panel may be set adjacently to the primary display panel by a predetermined angle with respect to the primary display panel, the personal computer further comprising a hinge mechanism for use in adjusting the predetermined angle.
The hinge mechanism may consist of an uniaxial hinge, the secondary display panel being rotatable around the uniaxial hinge towards both upper and lower sides with respect to the primary display panel.
The hinge mechanism may consist of a biaxial hinge including first and second axes, the secondary display panel being rotatable around the first axis towards both upper and lower sides with respect to the primary display panel, the secondary display panel being rotatable around the second axis towards both left and right sides with respect to the primary display panel.
The personal computer may be a notebook-size personal computer.
The personal computer may be a desktop personal computer.
According to another aspect of the present invention, there is provided a display apparatus which is for use in combination with a personal computer and which displays a plurality of images, comprising: a body of the display apparatus; a primary panel provided on a front side of the body; and at least one secondary panel which is provided adjacently to the primary panel.
