Description

[0001] PORTABLE DISPLAY DEVICE [0002]

The present invention relates to a method of using two displays as a single screen, and more particularly to a structure in which the input device can be used as a single input device even when the input device is mounted on the display.

In order to enlarge the screen in a portable manner, the two displays are interconnected to have the same effect as using one screen. Various flat panel displays such as LCD, OLED, FED, PDP, and electric paper can be used as the flat panel display panel.

To this end, a separate panel housing capable of folding and unfolding is provided. When the display is mounted on each of the panel housings, the displays are mutually adjacently arranged.

However, even if the structure is contiguous, a screen non-display area is generated by using two separate displays. Here, the screen non-display area is caused by the thickness of the boundary line, the protective plate or protective member, the thickness of the panel housing, and the clearance between the joints between the display panels.

In addition, one side of the display is effectively designed to minimize the seam which is a non-display area between the displays. To this end, one side minimizes the seams by effectively arranging displays that are designed to be adjacent to one another.

The input device for inputting information is provided on the same plane as the display, so that the input device can be used more than once.

As the flat panel display panel used in the present invention, flat panel display forms such as LCD, OLED, FED, PDP, and electric paper can be used. Hereinafter, a detailed embodiment will be described according to an embodiment of the present invention.

- Example 1 -

1 and 2 are views showing a foldable portable display device of the present invention.

As shown in Fig. 1, the folding portable display apparatus of the present invention is provided with two display units 2 and 4 and two panel housings 20 and 40 with the display unit mounted thereon. In addition, the panel housings 20 and 40 are provided with circuits, parts, and the like for driving or mounting the display.

The two panel housings 20 and 40 are connected by a connecting shaft 6 capable of folding and unfolding. In this embodiment, the connecting shaft 6 is a hinge. However, any means of enabling folding and unfolding does not necessarily mean that a hinge is used.

That is, if the two panel housings can be connected to each other so that they can be opened and closed, even if they are not in the form of a hinge or a shaft.

Fig. 2 is a view showing a state in which the foldable portable display device of the present invention is folded.

Covering means (85) are provided on the side surfaces of the panel housings (20, 40). The cover means 85 is positioned behind the display when the display 2 or 4 is unfolded but covers the display side when the display 2 or 4 is folded. In the case of the cover means 85, a side cover 85a for blocking the side surface is further provided.

In order to make the distance between the displays 2 and 4 close to each other, a side wall of the panel housings 20 and 40 protecting the display side in the joint portion where the displays 2 and 4 are connected is formed thin. At this time, the cover means 85 protects the displays 2 and 4 from physical impact.

Figs. 3 to 9 are views showing an input device and a display. Fig.

In particular, the method of the input device applicable to the present invention has been described in Figs.

3 is a diagram showing a positional relationship between an input device and a display. As shown in FIG. 3 (A), there is an OUT-Cell type in which the input device 200 and the display 2 are separated from each other by a predetermined distance. And an on-cell system in which the input device 200 is located. There is also an in-cell method in which a micro sensor is inserted into a display device in a completely different manner.

That is, the present invention applies to all of the input devices for inputting information on the display (2) and (4).

Fig. 4 is an embodiment showing the manner of the sensor inserted into the display. The figure shows one pixel in the display 2. The pixel includes three pixels of R (Red), G (Green) and B (Blue). Also, a TFT (Thin Film Transistor) element is also provided in an area of one portion of the pixel and a sensor is provided together with the element.

4 (A) is a diagram showing an embodiment in which the micro-optical sensor 207 is incorporated. The square shown in (A) shows that there are three pixels in one pixel. That is, the TFT element and the micro-optical sensor 207 are provided in the pixel.

The sensor X-line 207b and the sensor Y-line 207c are connected to the optical sensor 207 so that the coordinate position value can be known.

FIG. 4B is a view showing an embodiment in which a sensor of a micro switch (207a) type is incorporated. When a portion for displaying a screen in the displays 2 and 4 is referred to as a display panel, the panel is composed of two substrates. When a pressure is applied to the outside of the substrate, a micro switch 207a, Is detected. Similarly, the sensor X-line 207b and the sensor Y-line 207c are connected to the micro switch 207a, and the position can be known.

In addition, it is a matter of course that the principle of the present invention is applied to a sensor that can be inserted into display pixels other than the above two methods.

5 is a sectional view of the input device. FIG. 5 (A) and FIG. 5 (B) are views showing a capacitance method and a resistance film method, respectively.

That is, an electrode plate 241 is provided under the protection plate 240 in FIG. 2A, and the electrode plate 241 is formed of one or two films coated with a transparent electrode. When a hand or a pin or the like capable of conducting electric current is brought into contact with the upper portion of the protection plate 240, the position of the contact portion is sensed.

2B shows two films 241a and 241b coated with a transparent electrode on the protective plate 240 so as to face each other while maintaining a predetermined gap therebetween. When the pressure is applied, the position of the portion where the pressure is applied is detected.

In addition, an external protection plate (or a conversion plate) 240a may be further provided on the upper end of the input device. Then, the protective plate 240a is coated with a desired pattern.

FIG. 6 is a cross-sectional view of the display, in which the pixel electrode has a shape closer to the junction. The pixel electrode constitutes an active area in which the screen is displayed, which means that the active area is closer to the joint part.

The distance between the display boundary 2g and the closest pixel 2n is very important in the joint 8 regardless of whether a flat display is used or not , It is a matter of course that design values designed in the present invention can be directly applied to all flat panel displays.

In the portable display device of the present invention, an OLED method is used, and a cross section of the structure is shown.

The displays 2 and 4 are provided with an insulating layer 53, an electrode 54, a coating electrode 58 and an organic multi-layered film 53 on a substrate 51, (56).

Then, the substrate 51 is covered with the cover substrate 52. At this time, the partition 2f seals the display edge. In addition, a driving portion 2k is provided on the opposite side of the joint portion.

On the other hand, when the display 2 is mounted on the chassis 16, only the portion P corresponding to the screen non-display region should be covered in the joint portion even if the chassis 16 covers only the display side or cover the upper portion (Shown in the drawing)

In addition, the design structure of the joint portion is not limited to the OLED system, and all the flat panel display devices are applicable.

7 is an enlarged view of a joint portion on the display. In the present invention, since the two screens are connected to minimize the joint, the display (2) and (4) must be designed to reduce the joint (screen non-display area).

The distance J between the adjacent pixel 2n and the partition 2f is within 1 mm when there is a pixel 2n closest to the joint 8 as shown in the figure.

The thickness K of the partition wall 2f is also set to 1 mm or less and at least 0.01 mm or more. Therefore, the distance from the pixel 2n closest to the joint to the edge 2g of the display 2 (4) should be within 2 mm.

Here, the partition wall 2f denotes a boundary between the inside and the outside at the display edge.

On the other hand, the displays 2 and 4 are usually mounted on a chassis 16, which is made of a metal such as aluminum or an alloy. A display module and a display driving unit or a backlight unit (when the display is an LCD) are mounted on the chassis.

At this time, the chassis need not necessarily be made of a metal material, but may be in the form of a structure made of plastic resin. It is also possible to use a mixture of metal materials and plastic materials.

In addition, the thickness of the chassis 16 at the joint portion 8 should be within a range of 0.01 mm or more and 1 mm or less. However, the maximum effective thickness of the chassis 16 should not exceed 0.5 mm. In the joint portion, an open structure is also possible.

It is needless to say that the boundary between the display border line 2g and the partition wall 2f does not need to completely coincide with each other in the joint portion 8 and the partition wall 2f can be provided within a range of 0.5 mm or less from the boundary line 2g Do.

8 is an enlarged view of a joint portion of the input device, and is a form of a capacitance type. And an active area in the joint part when an area capable of detecting contact in the input device is referred to as an active area.

As shown in the figure, the distance from the active area boundary 223a to the input device boundary 250g is within 1mm - 2mm or 3mm.

9 is an enlarged view of a joint portion in the resistance film method of the input device. That is, two substrates (transparent plastic) coated with a transparent electrode are mutually coupled.

The spacing M between the bus 250n and the partition on the joint 8 should be within 1 mm and the thickness L of the partition 250f should be within 0.01 mm to 1 mm. It goes without saying that the interval M may be 0 mm, of course.

Wherein the barrier ribs are used to couple the conductor films 220 to one another or to join the other plates in the input device.

In the joint portion 8, the distance from the electrode line 250n to the boundary 250g of the input device 200 is within 2 mm. Alternatively, the distance from the boundary of the active area 250a to the boundary 250g of the input device 200 is within 2 mm (or 3 mm).

Of course, it is needless to say that the boundary between the boundary 250g of the joint 8 and the partition 250f does not need to completely coincide with each other, and it is of course possible to provide the partition 250f within a range of 0.5 mm or less at the boundary 250g .

The principle of the present invention is applied to an input device capable of inputting information on a flat plate in addition to the above two input devices (electrostatic capacity type and resistance film type).

Figs. 10 and 11 are views showing embodiments in which a display is mounted on a panel housing. Fig.

10, when the panel housings 20 and 40 are unfolded and brought into close contact with each other, the display units 2 and 4 become adjacent to each other. At this time, the display (2) (4) is provided on the side upper end of the panel housing (20) (40).

Various circuits and devices 25 and 45 are provided in the panel housings 20 and 40 and a pedestal 26 and 46 for supporting the display 2 and 4 are also provided. A lid 24 is provided on the edge of the display 2 (4). Meanwhile, the cover means 85 is not shown for the sake of simplicity. Further, an extension line of the rotation center A meets the surface of the lid 24. That is, the height of the center of rotation is the height of the cover.

When the displays 2 and 4 are in close contact with each other, they may be in contact with each other, but in some cases, the spacing between the displays may be about 0.005 to 0.2 mm. When the gap is small, a thin protective film is used to seal the display side.

Figure 11 is a view of an embodiment having a protective means at the top of the display. As shown in the figure, by providing a step 24a on the side of the lid 24 and the panel housings 20 and 40 and attaching the protective means 14 to the step 24a, The protective means 14 can be mounted on the front surface of the display 2 (4).

An optical means (27) may be provided under the protection means (14). At this time, the optical means is means for optically reducing the joint which is the interface between the displays 2 and 4. The protection means 14 is formed to be thinner than 1 mm or 0.5 mm.

At this time, in the present invention, the optical means is an optical plate functioning to reduce the screen non-display region occurring at the boundary between the two displays. As the optical means, a lens for refracting light, a micro lens, a micro prism, or the like may be used. In addition, various means for moving the path of light toward the display boundary can be used.

That is, in the case of an in-cell type input device, mutual distances between the micro sensors can be limited by the joint portion 8. When the information on the display (2) (4) is input at the touch or point and the area of the portion sensing the input information is the sensing area, the portion provided on the first display is referred to as the first sensing area second The distance between the first sensing area and the second sensing area in the joints 8 of the display 2 and the display 4 may be the same as the non-display area.

- Example 2 -

12 to 15 show block diagrams and flowcharts of a portable display device including an input device and a display.

The present invention includes two displays 2 and 4, two input devices 250-1 and 250-2, and an input device at the top of the display.

12 is a block diagram of the present invention, which is a block diagram showing display and input device control.

In the drawing, the central processing unit 105 is control means for controlling the overall operation of the portable display device of the present invention. The RAM 121 controls the execution program of the display device. The RAM 122 stores data generated during the execution of the program. The RAM 123 stores data required by the user and data .

The R / F unit 124 is a radio frequency, tunes to an RF channel, amplifies an input voice signal, and converts an RF signal received from the antenna into an intermediate frequency signal. The input unit 110 includes various input devices, a numeric key, a menu key, and a selection key.

There are a display driving circuit 130a for driving the display by the output of the central processing unit 105 and first and second displays 2 and 4 for displaying information on the screen in accordance with the output signal of the driving circuit.

Also, the gravity sensor 235 is provided to determine whether the two displays 2 and 4 are positioned vertically or horizontally. As a sensor for reflecting the position of the portable display device to the screen control, it is of course also applicable to the present invention as a sensor generally used in a mobile phone such as an acceleration sensor, a position sensor, and a gyroscope.

In addition, the central processing unit controls the first and second input devices 250-1 and 250-2 through the first and second input device controllers 1401-1 and 140-2. That is, since there are two input devices 250-1 and 250-2, two input device control units 1401-1 and 140-2 exist to control corresponding input devices respectively.

In this case, when an in-cell type micro sensor is built in the display pixel, a sensor control unit is provided instead of the input device control unit. The sensor control unit supplies a current to the microsensor and senses a signal of the microsensor.

Then, the X and Y axes are connected to each other in the form of a micro sensor and a matrix, and the position coordinates of the sensed sensor can be obtained.

That is, the first and second sensors may be used instead of the first and second input devices. Therefore, it means a micro sensor inserted in the first and second sensor display pixels. Therefore, the set of micro sensors inserted into the first display 2 may be referred to as a first sensor, and the set of micro sensors inserted into the second display 4 may be referred to as a second sensor.

The input devices 250-1 and 250-2 shown in the block diagram of FIG. 5 are the same as the input devices 200 and 400 shown in the other drawings of the present invention.

13-14 illustrate an embodiment of a block diagram of the present invention.

13, a central processing unit or main body control unit 105 includes a control unit 110, a memory 120, a time controller 125, a display driving unit 130, and an input device driving unit 140, .

That is, each of the elements functioning as the controller 110, the memory 120, the time controller 125, the display driver 130, and the input device driver 140 are all provided in the body controller 105, ≪ / RTI >

The display driver 130 divides the screen and sends data to the first display 2 and the second display 4, respectively. In addition, the input device driver 140 also calibrates and adjusts the signals output from the first input device 250-1 and the second input device 250-2.

In order to display the screen of the display 2 or 4, a source 2b (4b) for providing a data signal and a gate 2c (4c) for providing a line selection signal, .

Of course, at this time, the data lines of the first display 2 and the data lines of the second display are not necessarily divided into 1: 1. 2: 3, 10: 6, 6: 4, and the like. That is, the capacities of the first display 2 and the second display 4 do not necessarily have to be 1: 1 according to the terminal design.

FIG. 14 is a detailed view of the input device driver 140. FIG.

First, the calibration function performing unit 141 performs a calibration function with respect to the input device 250 when the system is initially operated. A panel signal corresponding to an accurate coordinate value of the input device 250 is selected according to a calibration function performed by the calibration function performing unit 141. [

That is, the signal of the input device 250 corresponding to the coordinate value is selected according to the resolution of the display (2) (4) and the number of lines of the gate and gate, and the selected signal is provided to the control unit 110. Accordingly, the controller 110 stores and manages the coordinate values corresponding to the panel signals.

The average value detection time adjustment unit 143 adjusts the average value detection times for the panel signals output from the input device 250 based on the screen resolution information of the display device 2 (4) provided from the control unit 110. [ When the screen resolution is changed to a high resolution, the average value detection number is adjusted to be larger than a previously set value. On the contrary, when the screen resolution is changed to a low resolution, the average value detection number is adjusted to be smaller than the previously set value.

The average value detecting unit 142 detects an average value of the panel signals transmitted from the input device 250 based on the average value detection number adjusted by the average value detection number adjusting unit 143. [ The detected average value is transmitted to the adjusted panel signal generator 144.

The adjusted panel signal generator 144 uses the changed screen resolution of the display device 2 or 4 provided from the controller 110 or the position information of the display screen changed by the virtual scroll and the average value of the currently input panel signals Thereby generating an adjusted panel signal.

In this case, the first input device 250-1 and the second input device 250-2 are provided in the present invention. Therefore, in the input device driver 140, signal control for the first input device 250-1 The signal control of the second input device 250-2 is performed.

Under the control of the time controller 125 and the control unit 110, however, the switching device 145 switches between the first input device 250-1 and the second input device 250-2 alternately in the input device driver 140, .

The first input device processes the signal generated in the input device 250-1 and then processes the signal generated in the second input device, (250-2).

As shown in this drawing, when the switching device 145 is used, one driving device can be used to drive two or more input devices. However, the switching device 145 may not use the switching device 145, It is a matter of course that the input device driver may be provided for the number of input devices.

Fig. 15 is a diagram showing a flowchart of the present invention.

When the display apparatus of the present invention is activated, the main body control unit 105 also operates to operate the respective apparatuses. (Step 400)

The control unit 110 in the main body control unit 105 divides the screen display data stored in the memory 120 or the received screen display data and controls the display driver 130 and the time display unit 130 under the control of the control unit 105, The controller 125 performs the operation.

Accordingly, the main body control unit 105 divides the screen and transmits screen data information corresponding to the first display and the second display, respectively (operation 402)

Then, the switching device 145 drives the input device driver 140 to drive the first input device 250-1. That is, information output from the first input device is controlled (Step 404). Then, the information output from the first input device is controlled according to the screen display information of the first display 2 (Step 406)

Similarly, the input device driver controls the output signal from the second input device by the switching device 145 (step 408) and controls the signal of the second input device according to the display information of the second display device 410 step)

If there is no stop command, the main body control unit continuously divides the screen and drives each input apparatus. However, if there is a stop command, the series of such functions is terminated (steps 412 and 414)

As a result, the first display and the second display are displayed by vertically or horizontally dividing one full screen, and the first display and the second display are mutually adjacently arranged, and the first display and the second display correspond to the output information of the first display A first input device and a second input device corresponding to output information of the second display are provided and the input devices are also adjacent to each other so that the two input devices are used as one input device.

- Example 3 -

Figs. 16 to 27 are views showing a structure in which a display, an input device, or optical means are mounted.

16 is an embodiment in which the display and the input device are separated by the same distance.

As shown in the figure, when the portion indicated by "V" is formed into a protective film, the protective film should be as thin as possible and firm, so use a metal film or a resin film or a material in which a resin film is coated with a metal or an inorganic film Can be used.

When the portion denoted by "V" is a protective film or protective means, the thickness is preferably set to be not less than 0.005 mm and not more than 0.5 mm. In this case, the sealing effect may be more important than protecting from physical impact. The distance between the two displays (2) and (4) is at least 0.01 mm and the maximum is 1 mm. Similarly, the interval between the two input devices 200 and 400 is at least 0.01 mm and the maximum is 1 mm.

When the "V" is in the form of a protective means, the thickness can be set within 1.5 mm.

On the other hand, the portion indicated by "V" can be formed integrally with the panel housing without using any other protection means. The side walls of the panel housings 20 and 40 protect the side surfaces of the display devices 20 and 40 and the side surfaces of the input devices 200 and 400.

At this time, the portion indicated by "V" is shown thinner than the panel housing side walls 20 and 40 in order to make the distance between the displays as close as possible. That is, when it is thinner than the side wall of the panel housing, it is preferable to be within 0.5 mm, but it may be within 1 mm maximum.

That is, the "V" portion may be thicker than the other side walls of the panel housings 20 and 40. [

In other words, the distance between the displays 2 and 4 may be at least 0.1 mm to at most 4 mm, even if it is thicker than the side walls of the panel housings 20 and 40. As a result,

And, even if the thickness of "V" is only 0.5 mm, the distance between the displays 2 and 4 can be 4 mm. In addition, when the side of the display or the side of the input device is separated from the side of the input device, the space may be a space therebetween, but a shock absorbing member may be provided to absorb shock.

Naturally, the distance between the joints 8 and the input devices 200 and 400 is at least 0.01 mm and at most 4 mm.

17 shows an embodiment in which the distances between the input devices are closer than the distances between the displays.

If the plate provided between the input devices 200 and 400 is called V1 and the plate provided between the displays 2 and 4 is V2, the distance of V1 is shorter than the distance of V2 small. That is, the distance between the display devices 2 and 4 is shorter than the distance between the input devices 200 and 400. [

At this time, both of "V1" and "V2" may be formed integrally with the side wall of the joint of the panel housings 20,

Further, only "V2" may be integrally formed with the side wall of the joint of the panel housings 20, 40, and "V1" may be a separate protective film or protective means. In the case of using a protective film or a protective means, the protective means and the film embodiment described in the previous embodiment are directly followed.

Of course, both "V1" and "V2" can be made a protective measure distinct from the panel housing. In this case, the protective means protects the side of the display (2) (4) and the side of the input device (200) (400).

The thickness of "V2" is preferably 1.5 mm or less, and the thickness of "V1" And according to the embodiment of "V ".

18 to 20 are views of an embodiment with optical means.

Example 6 -

Figures 44-48 are views of embodiments illustrating input methods.

Figs. 44 and 45 are diagrams for explaining an embodiment for inputting information on the surface of the display (2) (4) in the display device of the present invention, Fig. 44 is a mode for inputting information in one screen mode, Is a form of inputting information in two screen modes.

Herein, when inputting information through an input device, one screen mode is a mode in which two screens are used as one screen, and two screen modes are modes in which information is input by separating two screens.

Figure 44 (A) shows an embodiment in which two or more input points 147 are recognized, and the point 147 is also recognized as a path 147a (indicated by an arrow). At this time, even if two points 147 exist over two screens, they are recognized as if they exist on one screen.

The central processing unit 105 or the control unit 110 controls the movement of the two points 147 when the two points are set to be enlarged when the two points move inward by the predetermined program and when the two points move outward, The display driver 130a and the display driver 130a are operated to display the screen. That is, two screens are combined to form a single screen to enlarge or reduce.

FIG. 44 (B) shows an embodiment in which two or more points 147 are selected when a pattern (or an image) 147b is selected. Even when the pattern (or image) 147b spans two screens, it is recognized as when it is on one screen.

Here, the point is a point indicating a position for inputting information when information is input on the display (2) (4) screen.

If the pattern (or image) is enlarged when two points selected by a predetermined program are moved inward and the pattern (or image) is enlarged when the point is moved outward, the central processing unit 105 or the control unit 110 The display driver 130a transmits the screen information on which the pattern (or the image) is enlarged or reduced according to the movement of the two points 147 to display the enlarged or reduced screen.

In FIG. 44C, one point 147 selects a pattern (or image) 147b, indicating that when the point moves, the pattern (or image) 147b also moves along the movement path of the point 147 .

The central processing unit 105 or the control unit 110 moves the pattern (or the image) 147b by moving the point, and if the movement of the pattern (or the image) 147b is programmed The movement is like moving on one screen.

(C) shows the case where the point 147 moves left and right and the case of rotation, and the selected pattern (or the image) 147b can be rotated when the point 147 rotates.

Figure 44 (D) shows an embodiment in which one point 147 moves. Even if the moving path 147a is on two screens, it is like moving in one screen.

The central processing unit 105 or the control unit 110 sends information on the previous screen or the next screen to the display driving unit 130a by moving the point The subject screen can be displayed.

Likewise, when the movement path 147a of the point 147 is rotated, the conical surface can also be rotated.

45 is a view showing an embodiment of information input modes in two screen modes.

FIG. 45 (A) shows that a screen is displayed according to the movement path 147a when moving to a point 147 in one screen. In this case, the result is displayed only in one screen.

FIG. 45 (B) shows that one pattern (or image) 147b is selected in one screen. The pattern (or image) 147b can move into one screen and move to another screen according to the movement path 147a of the point 147. [

46 illustrates the height of the protection means 14 (or sidewalls or extended portions) present between two input devices 200, 400 (or two protective plates may be provided).

In the present invention, the protective means 14 (or side wall or extension) is provided between the two input devices 200, 400 or the protection plate.

Instead of the protection means 14, the side walls of the panel housings 10 and 40 may be provided or the side walls 24d and sidewall extension portions 24a may be extended from the lid frame (or frame) .

In order to reduce the inconvenience of movement between the two touch panels, it is preferable to restrict the H2 value to 2 mm or 3 mm or less. Naturally, the values of H2 and H3 are 0 or close to 0, which is convenient to use.

47 is a flowchart showing the flow of information input through the input device of the present invention.

When the display device of the present invention is started (step 300), the first and second displays are driven and the first and second input devices (or sensors) are also controlled (step 305).

The first and second sensors refer to a micro sensor inserted in a display pixel. The first and second sensors include a first sensor, a micro sensor (not shown) inserted in the second display 4, May be referred to as a second sensor.

At this time, the control of the input device is to send a current to the input device and to detect the coordinates at which information is input when the information is input to the input device. This detection is performed through the input device driver 140 and the central processing unit 105. [

And selects one screen mode or two screen modes (step 310)

One screen mode is to drive the first and second displays as one display, and the first and second input devices (or sensors) are controlled as one input device.

That is, the movement path 147a of the input point 147 is controlled to pass through one input device even if it passes through the first and second input devices 200 and 400.

As a result, the first and second displays are combined into one screen, and the coordinates corresponding to the coordinate values of the combined one screen are compared with the coordinate values input through the input device (sensor) And executes a program for displaying the program.

That is, when the input coordinate value is one point, two or more points, or the input coordinate value moves, the corresponding program is executed.

In the one-screen mode, it is determined whether the coordinate value input through the input device (or the sensor) has selected the coordinate value of the pattern (or image) displayed on the display. (Step 315)

If the pattern (or image) is not selected, the program is executed as if the information was inputted through one input device even if the input point and the movement path of the input point were both in the first and second input devices (Step 320). At this time, the central processing unit or the control unit executes the predetermined program as in the case where the pattern is not selected in the single screen mode as described in the previous embodiment.

Also, if a pattern (or an image) is selected, a pattern (or an image) selected as an input of one input device is displayed on the first and second input devices (or sensors) The moving program is executed (step 325).

At this time, when the pattern is selected in the single screen mode as in the previous embodiment, the central processing unit or the control unit executes the predetermined program according to the number of points or the movement path of the point.

If the two screen modes are selected in step 310, a predetermined program is executed according to whether the pattern (or image) is selected in the two screen modes, the number of input points and the movement path (step 330)

That is, the program according to the number of points input in the two screen modes and the movement path of the point is executed as in the embodiment of the previous drawing.

In the single screen mode, the central processing unit or the control unit sends a driving signal to the display driver and displays the result on the first and second displays according to the program control result.

On the other hand, even if the first and second displays are used as a separate screen, the program is executed according to the input point and the movement path of the point, and the result is displayed on the first and second displays. Step 340)

Finally, the program execution result is displayed on the screen. If there is no stop command, the program moves to the initial step of step 305. If there is a stop command (step 345), the program is terminated.

48 is a view for explaining the principle of making two devices as one.

As shown in the drawing, the first and second input devices or the first and second displays have corresponding coordinates. In the present invention, since the input device or the display is separated from each other, the coordinates are separated as shown in FIG.

However, controlling two input devices as one input device connects each coordinate which is actually separated as shown in (B).
