Abstract

PROBLEM TO BE SOLVED: To provide a portable notebook computer that many persons can easily and simultaneously view display. SOLUTION: A second liquid display equipment 3 is provided on the back surface of a liquid display equipment part 2 being normally a cover part in structure where a part 1 including a computer mainbody part and a keyboard and the liquid display equipment part 2 are foled into halves. In the liquid display equipment 3, screen structure being equal to the liquid crystal display equipment on the front surface is provided so as to execute the same screen display and also to view the screen from both front surface and back surface. Since the second liquid crystal display equipment 3 becomes easy to break under exposure at the time of carrying the computer, slide-type protective shutters 4A and 4B for covering the display surface of the second liquid crystal display equipment from both side parts at the time of non-usage are provided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable notebook computer, and more particularly to a display device.

[0002]

2. Description of the Related Art In consideration of portability, a portable notebook computer is designed to have a small and thin outer shape and a light weight.

Further, the notebook computer adopts a liquid crystal display as its display device, and as shown in FIG. 3, a portion including a computer main body and a keyboard is provided for protection of the liquid crystal display and the keyboard and convenience of carrying. 1 and the liquid crystal display portion 2 are folded in two, so that they can be folded for carrying and widened for use.

With such a configuration, the notebook computer is used for taking it out of the office or the like from a portable port and using it at the destination. As a result, it is possible to easily realize a system (software) using a computer at the place where you bring it out, or a presentation using a computer, and you can visually appeal to the explanation that was usually done with materials such as paper,
Can carry out effective proposal activities.

[0005]

When carrying out a demonstration or a presentation by taking out a notebook computer, the conventional display device makes it difficult for a person who visits the demonstration or the presentation to see the display.

This is because the liquid crystal display has directivity and the screen is designed to be small. As shown in FIG. 4, the operator OP and the visitor V do not see one screen. If the angle is set so that the observer can easily see the display, it becomes difficult for the operator to see the display and the operation becomes difficult. If the angle is set so that the operator can easily see and operate the display, the display becomes difficult to see.

It is an object of the present invention to provide a notebook computer which is portable and facilitates a large number of people to view the display at the same time.

[0008]

According to the present invention, in order to make it easier for an operator and a visitor to see the screen at the same time, a second liquid crystal display is provided on the back side of the liquid crystal display part, and the operator can see the screen of the liquid crystal display on the front side. When viewing, the viewer will be able to see the screen on the second LCD on the back.
The following configuration is used.

In a notebook computer in which a portion including a computer main body portion and a keyboard portion and a liquid crystal display portion are covered and carried, and the liquid crystal display portion is opened to use a screen display on a front liquid crystal display when used, the liquid crystal The display part is provided with a second liquid crystal display on the back surface thereof, and a protective shutter for covering the surface of the second liquid crystal display when the computer is not used, and the computer main body part is provided with the front liquid crystal display. And a parallel drawing processing function of the second liquid crystal display.

1 is a front view (A), a rear view (B) and a side view (C) showing an embodiment of the present invention.

The notebook computer according to the present embodiment includes a computer main body and a portion 1 including a keyboard,
In the structure in which the liquid crystal display portion 2 is folded in half, the second liquid crystal display 3 is provided on the back surface of the liquid crystal display portion 2 which is usually a lid.

The second liquid crystal display 3 has a screen structure equivalent to that of a conventional liquid crystal display provided on the front surface of the liquid crystal display portion 2 and has a parallel drawing process by a computer main body so that the same screen display can be performed. Done.

Further, when the second liquid crystal display 3 is exposed for portability, the liquid crystal display 3 is easily damaged. Therefore, the slide type protective shutter 4A for covering the display surface of the liquid crystal display 3 from both sides when not in use, 4B is provided.

When the notebook computer according to the present embodiment is used for a demonstration or a presentation, the operator operates the OP while watching the liquid crystal display on the front side without being aware of the position of the observer V, as shown in FIG. Therefore, the visitor V can see the second liquid crystal display on the back side without being aware of the position of the operator OP.

When the operator OP or the like uses the computer by himself using a mouse or the like, the liquid crystal display part 2 is closed to the main body part 1 and the operation is performed while watching the second liquid crystal display. You can also

Further, the second liquid crystal display is not limited to one, but may be a foldable two-piece construction or a three-piece construction, and when the plurality of second liquid crystal displays are opened, 3 It is also possible to adopt a configuration capable of displaying more than the surface.

[0017]

As described above, according to the present invention, the second liquid crystal display device is provided on the rear surface of the liquid crystal display portion, and when the operator looks at the screen of the front liquid crystal display device, the visitor can see the second liquid crystal display device on the rear surface. Since we made it possible to see the screen on the liquid crystal display of, the operator and many visitors can see the same screen at the same time from the front and back of the display, and even from the side,
It becomes a notebook computer that is easy to use for demonstrations and presentations.
