However, the inactive window is displayed on the display unit of the liquid crystal display 200. , The active window may be displayed on the display unit 410 of the tablet terminal 400.
[Liquid crystal display legs]
10 and 11 are schematic views showing an example of the legs 290 of the liquid crystal display 200.

As shown in FIGS. 10 and 11, the leg 290 of the liquid crystal display 200 is provided with a protruding leg 291. The leg portion 291 is provided so as to be expandable and contractible from the leg portion 290 in the direction of the arrow X. Further, the leg portion 291 is provided with a plurality of uneven portions 295.

By locking the lower end of the tablet terminal 400 to one of the plurality of uneven portions 295, the inclination of the tablet terminal 400 can be set to a predetermined angle.

By changing the installation location on the plurality of uneven portions 295, it is possible to change the inclination of the tablet terminal 400 according to a plurality of predetermined angles.
The shape is not limited to unevenness, and any shape may be used as long as the inclination of the tablet terminal 400 can be changed according to a predetermined angle.

Although the liquid crystal display 200 has been described in the above embodiment, the present invention is not limited to this, and when the liquid crystal display 200 has a touch panel specification, the display unit 410 of the tablet terminal 400 is extended with respect to the liquid crystal display 200. In addition to displaying, the touch input area of the tablet terminal 400 may be expanded to the touch panel side of the liquid crystal display 200.
In such a case, the user can use the touch panel functions of the liquid crystal display 200 and the tablet terminal 400.

Further, when an interface (for example, USB) for using the touch panel of the liquid crystal display 200 exists on the liquid crystal display 200 side, the touch panel of the liquid crystal display 200 may be operated by using the interface.
[Other examples of system control flowchart]
FIG. 12 is a diagram showing another example of the control flowchart of the cooperative connection system 100. The tablet terminal 400 is connected to the liquid crystal display 200 by wire or wirelessly (step S11). The control unit 450 of the tablet terminal 400 detects the connection with the liquid crystal display 200 and detects the installation angle of the tablet terminal 400 (step S12).

Next, the control unit 450 of the tablet terminal 400 determines whether or not the installation angle is a predetermined angle, and also determines whether or not the predetermined angle is stable (step S13). Specifically, the tilt recognition unit 430 detects a predetermined angle for 5 seconds. The control unit 450 determines that the angle is stable when the angle change does not occur, and determines that the angle is not stable when the angle change occurs by about 5 degrees.
It is desirable that the determination time and the amount of angle change used when determining the stability can be arbitrarily set by the user.

When the control unit 450 determines that the tablet terminal 450 is stable at a predetermined angle, the control unit 450 determines that the tablet terminal 400 is mounted on the pedestal 500 (step S14).

On the other hand, when the control unit 450 determines that the tablet terminal 450 is not stable at a predetermined angle, the control unit 450 determines that the tablet terminal 400 is held by hand (step S24).

Next, after the process of step S14, the control unit 450 determines whether or not the angle is smaller than a predetermined angle (step S15).

When the tablet terminal 400 determines that the angle is smaller than a predetermined angle, the control unit 450 controls (state 1) in which the expansion direction of the screen is upward (step S16).

On the other hand, when the tablet terminal 400 determines that the angle is larger than the predetermined angle, the control unit 450 controls (state 2) to set the expansion direction of the screen to the horizontal direction (left) (step S17).

Next, after the process of step S24, the lower side and the upper side of the tablet terminal 400 are determined based on the information from the tilt recognition unit 430 at a predetermined angle of the tablet terminal 400 with respect to the horizontal plane, and the tablet terminal 400 is expanded upward. The display control (state 3) is performed (step S25).

Subsequently, it is determined whether or not the tablet terminal 400 has rotated with respect to the vertical axis of the display unit 410 of the tablet 400 with respect to the display surface (step S26). When it is determined that the tablet terminal 400 is not rotating (No in step S26), the state 3 is maintained and the process of step S26 is repeated.

When the control unit 450 of the tablet terminal 400 determines that the tablet terminal 400 has rotated (Yes in step S26), the control unit 450 changes the expansion direction of the screen of the tablet terminal 400 based on the information from the tilt recognition unit 430. (State 4) is performed (step S27).

Next, FIG. 13 is a schematic view showing an example when the tablet terminal 400 is rotated by 90 degrees.

As shown in FIG. 13, when the bottom side (floor side) of the tablet terminal 400 is the short side of the end portion of the tablet terminal 400, the expansion direction of the display unit 410 of the tablet terminal 400 is the short side on the opposite side. It becomes the direction.
However, when the control unit 450 determines that the bottom side (floor side) has been changed to the long side side by rotating the tablet terminal 400, the expansion direction of the display unit 410 of the tablet terminal 400 is the opposite long side direction. Is changed to.

In the above control flowchart, which direction of up / down / left / right extended display (state 1, state 2, state 3, state 4) is set in advance using the tablet terminal 400.
The positioning function of the tablet terminal 400 may be used to acquire the current position information, and the company and the home may set on / off of the cooperative connection system 100 based on the position information.
The location information may be acquired by using the GPS information of the tablet terminal 400, or by using radio waves transmitted from a base station such as a WIFI access point or LTE around the tablet terminal 400. Further, when the SSID of the wireless router at home is detected, it may be determined as home, and when the SSID of WIFISPOT of the company is detected, it may be determined as a company.

For example, the cooperative connection system 100 may be set to off based on the location information in the company, and the cooperative connection system 100 may be set to on based on the location information in the home.

In addition, the direction of the extended display is set to the horizontal direction (right) based on the position information and the predetermined angle in the company, and the direction of the extended display is set to the horizontal direction (left) based on the position information and the predetermined angle at home. You may.
In such a case, the user can easily change the extended display direction of the tablet terminal 400 according to the difference in the installation location of the liquid crystal display 200 and the tablet terminal 400 between the office and the home.

Further, the tablet terminal 400 may change the setting of the extended display direction of the screen according to a predetermined angle for each user by using the face recognition particularly mounted on the smartphone or the like.
In such a case, for example, each state of state 1, state 2, state 3, and state 4 in FIG. 12 can be individually set for each user.

When the tablet terminal 400 is connected to the liquid crystal display 200, the device information of the liquid crystal display 200 is acquired by using the "Display Data Channel Interface" VESA (Video Electronics Standards Association) standard (DDC / CI). The device information and the recommended angle of the display 200 recorded in advance on the 400 can be confirmed, and the recommended angle of the tablet terminal 400 for extended display can be set on the tablet terminal 400.
In such a case, for example, it is possible to perform initial settings according to the model number of the liquid crystal display.
The tablet terminal 400 may acquire the device information of the display 200 and the combination information of the recommended angle from a specific server on the Internet.
Next, an example of controlling the logical connection points of the screens of the display unit 210 and the display unit 410 will be described.

As shown in FIG. 14, the display unit 210 is larger than the display unit 410, and has a logical connection point with each other and a boundary between the display unit 210 and the display unit 410.
Therefore, when the display unit 210 of the liquid crystal display 200 and the display unit 410 of the tablet terminal 400 display the screen resolution of the display, for example, the total number of pixels (horizontal × vertical pixels) displayed on the display unit with different screen resolutions. There is.
For example, the resolution of the display unit 210 is 1920 × 1080, and the resolution of the display unit 410 is 1024 × 768.
That is, the screen resolution of the display unit 210 is larger than that of the display unit 410. In that case, when the display unit 410 is arranged below the display unit 210, the difference of 840 pixels between the horizontal size (1920) of the display unit 210 and the horizontal size (1080) of the display unit 410 is the display unit. There is no logical contact between 210 and the horizontal portion of the screen of the display unit 410.
As a result, when the mouse cursors 220 and 420 are moved from the display unit 210 having a large resolution to the display unit 410 having a small resolution, for example, the mouse cursor 220, can be seen at the boundary between the display unit 210 and the display unit 410 due to the difference in resolution. The movement of 420 may not be smooth.
Therefore, as shown in FIG. 15, when the screen moves an image such as a mouse cursor 220, 420, a folder, or a file from the display unit 210 to the display unit 410, the display unit 210 is logically connected to the display. When the image is located at the boundary between the display unit 410 and the display unit 410, the screens of the display unit 210 and the display unit 410 are logically in contact with each other so that the image can be smoothly moved from the display unit 210 to the display unit 410. The connection point mark 2424 indicating the place (or the place not in contact with the place) may be displayed on the display unit 210.

Further, as shown in FIG. 16, when moving the mouse cursor 220, 420 or an image such as a folder or a file from the display unit 410 to the display unit 210, the display unit 210 is logically connected to the display unit. When the image is located at the boundary with the display unit 410, the position where the screens of the display unit 210 and the display unit 410 are logically contacted so that the image can be smoothly moved from the display unit 410 to the display unit 210. The connection point mark 4242 indicating (or a place not in contact with each other) may be displayed on the display unit 410.
By dragging the connection location mark along the boundary with the mouse cursor, the location where the screens of the display unit 210 and the display unit 410 are logically in contact with each other may be adjusted.
For example, in FIG. 17, the screen is logically connected so that the left end of the display unit 410 is connected to the left end of the display unit 210, but the connection point mark is dragged along the boundary with the mouse cursors 220 and 420. Therefore, the position where the left end of the display unit 410 is logically connected to the display unit 210 is changed along the boundary, or the center of the display unit 210 and the display unit 410 is changed so as to be aligned with each other. Can be done.
By doing so, the user can easily adjust the logical connection position of the screens of the display unit 210 and the display unit 410 according to the physical arrangement of the actual liquid crystal display 200 and the tablet terminal 400.
Further, as shown in FIGS. 18 (a), 18 (a), 18 (d), the mouse cursors 220, 420, folders, files, etc. from the display unit 210 having a screen resolution larger than that of the display unit 410 to the display unit 410. When moving the image 230, if the image 230 is located at a position where the screens of the display unit 210 and the display unit 410 are not logically in contact with each other, the image 230 can be smoothly moved from the display unit 210 to the display unit 410. As such, the mouse cursor 220, 420, or a folder, file, etc. is automatically placed at the closest point (the position having the width of the image 430) where the screens of the display unit 210 and the display unit 410 are logically contacted. The images 230 and 430 may be moved, and the images 230 and 430 may be smoothly moved from the display unit 210 to the end of the display unit 410.

That is, in FIG. 18, when the images 230 and 430 are moved from the portion of the display unit 210 that is not logically in contact with the display unit 410, the images 230 and 430 are displayed on the display unit 410 closest to the portion. Will be done.
Further, as shown in FIGS. 19 (a), 19 (a), 19 (d), the mouse cursors 220, 420, folders, files, etc. from the display unit 210 having a screen resolution larger than that of the display unit 410 to the display unit 410. When moving the image 230, if the image 230 is located at a position where the screens of the display unit 210 and the display unit 410 are not logically in contact with each other, the image 230 can be smoothly moved from the display unit 210 to the display unit 410. As described above, the images 230 and 430 may be moved according to the ratio of the screen sizes of the display unit 410 and the display unit 210.
In this case, the images 230 and 430 can be smoothly moved even when they are moved in the reverse order of FIGS. 19A, 19D, and 19D.

As described above, in the cooperative connection system 100, the user installs the tablet terminal 400 in the space under the front of the liquid crystal display 200 in a state where the tablet terminal 400 is connected to the liquid crystal display 200 and the tablet terminal 400 is slightly raised from the laid state. In this case, for example, the liquid crystal display 200 can be used as the main screen and the tablet terminal 400 can be used as the sub screen.

As a result, when performing mouse operations such as moving files on the screen while effectively utilizing the space under the front of the liquid crystal display 200, from top to bottom (from the liquid crystal display 200 side to the tablet terminal 400 side) and from bottom to top (from the liquid crystal display 200 side to the tablet terminal 400 side). Natural operations such as (from the tablet terminal 400 side to the liquid crystal display 200 side) can be performed. Further, a plurality of predetermined angles of the tablet terminal 400 may exist, and the predetermined angles may have an angle width. For example, when the tablet terminal 400 is in a state along the vertical direction (so-called standing state, an angle larger than a predetermined angle expanding upward), a sub screen in which the horizontal direction of the screen of the tablet terminal 400 is expanded is used. You can also do it.
Further, when the tablet terminal 400 is erected in the normal direction, the left direction may be expanded, and when the tablet terminal 400 is turned upside down and arranged along the vertical direction (standing state), the right direction is expanded. May be good.

Further, even when the display unit 410 of the tablet terminal 400 is small, the user can display the display of the tablet terminal 400 on the display unit 210 of the liquid crystal display 200. At that time, the display unit 210 of the liquid crystal display 200 having a large screen can be used as the main screen, and the display unit 410 of the tablet terminal 400 having a small screen can be used as a sub screen as a multi-screen environment.

In particular, in order to effectively utilize a narrow desk, it is preferable to effectively utilize the space under the liquid crystal display 200. Considering the health of the user, it is desirable that the liquid crystal display 200 and the user be separated by a certain distance as a measure against eyestrain, and the display unit 210 of the liquid crystal display 200 is positioned above the ground surface by the legs 290. I often do it. That is, there is often a space (space that can be utilized) by the legs 290 under the display unit 210.

That is, it is better to use the cooperative connection system 100 than to place the sub-liquid crystal display on the side of the liquid crystal display 200. By using the cooperative connection system 100, there is a space that can be utilized in front of the lower side of the display unit 210 of the liquid crystal display 200, and if a sub liquid crystal display is installed in the space, the desk can be effectively used. Can be done.

Further, if the sub liquid crystal display is placed on the side side of the liquid crystal display 200, it is necessary to shake the head when viewing the main screen and the sub screen, which is troublesome. However, in the cooperative connection system 100 when the lower space of the liquid crystal display 200 is effectively used, it is not necessary to shake the head from side to side.
Of course, in the cooperative connection system 100, it is possible to effectively use the side surface of the liquid crystal display 200 according to the user's taste and usage environment.
Then, if the tablet is made into a sub-screen with such a configuration and the keyboard and mouse are wirelessly connected to the tablet by Bluetooth (registered trademark) or the like, the user's usability is improved.

Further, in this embodiment, the liquid crystal display 200 is used as the main liquid crystal display and the tablet terminal 400 is used as the sub display.
The liquid crystal display 200 can be used as a sub liquid crystal display, and the tablet terminal can be used as a main display.
