C. Explanation of the Prior Art and Prior Art As an example to explain the prior art, consider the case where a character string is displayed on a display device. FIG. 4 is an explanatory diagram illustrating a conventional display method.The following description will be made with reference to FIG.

In the figure, 20 indicates a display screen of a display device, and 21 indicates a mouse, which is known as an input device for detecting the amount of movement.

As shown in Figure (a), when trying to display text on a screen, it is usually not possible to display all the text on one screen because the size of the screen is finite.

This friend displays only part of the text at a time, and moves the display range as necessary. Mouse 21. d
, is used to indicate the amount of movement of the display range. At this time, there are two ways to associate the direction of movement of the mouse with the direction of movement of the display range.

One is to think of mouse movement as text movement. In this case, when the mouse moves in the direction of the arrow 1(a), the displayed text moves as shown in FIG. 1(b). Another idea is to think of moving the mouse as moving the entire display device.

In this case, when the mouse moves in the same direction as in the previous example, the displayed text moves as shown in Figure <c>.

When moving the entire screen in a certain direction in this way, a completely opposite operation may be used.

Text 'E?' using a computer and display device. L'
This method of displaying information is an attempt to simulate the conventional method of writing entire sentences on paper by digitizing it.

However, since there are restrictions on the size of the display screen, a new operation is required in which the display range must be selected using the display window.To realize this new operation, as mentioned above, a mouse-like A method of selecting a display range using an input device has been adopted, but this method has a problem in that it is difficult to adjust to human intuition.

On the other hand, if we consider the case of a human being reading a text placed on a piece of paper, if the text is written over a wide area and he is in fL, he will move his face and even move his body to pick up the target. look.

Humans perceive text as an expanse on a two-dimensional plane, so
Even when it comes to moving the paper, it is more intuitive and convenient to look in that direction.

Recently, thin flat panel display devices, as typified by liquid crystal display panels, have become larger in screen size and put into practical use.

By adopting this simple device, you can
It is possible to realize Nibley mounting, and it can be displayed as if it were drawn on paper.

Two Problems Solved by the D0 Invention The present invention has been made against the background as described above. An object of the present invention is to provide a display device 41.

Furthermore, in a display method in which display data stored in an image memory is displayed in its entirety on -i using a display device with a display screen of a limited size, an easy-to-handle method for indicating the display range of the display data is provided. The aim is to realize this.

E. Means for Continuously Accomplishing the Aim To achieve the above object, the present invention includes a moving motion detecting means rotatably supported on the bottom surface of the flat display device and detecting one movement of the display device by the rotation of a fixed ball. The setting is the feet.

Flat display device configured with 20 or more functions
When □ is moved on a flat plate such as a desk, the movement amount detection means detects the entire movement amount of the device and connects it to the outside.
The amount of movement is sent to a digital device such as a computer.

The digital device receives and displays constant movement amount in the display range.
1 and send the display contents to the display device.

Embodiments Hereinafter, embodiments of a flat panel display device according to the present invention will be described with reference to all the drawings.

FIG. 1 is a three-dimensional view of a flat panel display device according to the present invention. In FIG. 1, reference numeral 1 shows a flat panel display device. 2 is a flat panel display device. In order to be able to use this device by placing it on a flat plate such as a desk, a thin display device such as a liquid crystal display panel or an EL display panel is used. 3 indicates the entire device. This is a case that covers.

A movement amount detection means 4 is provided on the lower surface of the case 3. The movement amount detection means 4 detects and outputs the entire rotation amount of the rotatably supported detection ball 4a, and can be realized by the technology employed in a mouse, which is a computer input device. Reference numeral 5 denotes an auxiliary ball 1 which is held in the device together with the detection ball 4a. 6 is a signal line that receives data to be displayed on the flat display device (chair 2) and transmits the amount of movement detected by the movement amount detection means 4.

1 This device is used by being placed on a flat plate, and when the device is moved, the detection ball 4a rotates due to friction with the flat plate and is detected as the amount of movement. This movement -xi is transmitted to a digital device such as a computer through the signal line 6VC.
