1 is a configuration diagram of a screen division monitor according to a first embodiment of the present invention.

Referring to FIG. 1, the screen division monitor 100 according to the first embodiment of the present invention includes a screen setting memory unit 150 for storing a screen area of a monitor and a resolution corresponding to the screen area, A screen selection unit 140 for receiving a screen area and a resolution corresponding to the screen area input to the screen selection input unit 140 from the screen setting memory unit 150, A screen information transfer unit 190 for transferring the screen information to the first terminal 10 and the second terminal 20 connected to the first terminal 10, A first image input unit 110 for receiving a video signal of the first terminal and a second image input unit 110 for receiving a video signal of the second terminal in accordance with the resolution transmitted from the screen information transmitting unit to the second terminal 20, An image input unit 120, a first image input unit 110, A video selector 130 for combining the video signal received from the first video input unit 120 according to the screen area and a video display unit 170 for displaying the synthesized video signal transmitted from the video selector 130 And a selection unit 140 for selecting a resolution suitable for the screen area input from the screen selection input unit 140 in the memory unit 150 and delivering the selected resolution to the screen information transfer unit 190, And a monitor control unit 160 for transmitting the monitor control signal to the monitor control unit 160.

A feature of the present invention is that a first terminal 10 (hereinafter referred to as an 'internal network PC') and a second terminal 20 (hereinafter, referred to as 'internal network PC'), which are two PCs connected to an internal business network and an external network, (Hereinafter, referred to as an " external network PC ") is physically separated from the internal network screen, and a single monitor 100 is used to select an internal network screen or an external network screen to display the entire screen, The external network screen is divided and displayed on the divided screen at the same time.

The monitor 100 may use a conventional LCD monitor, but it is preferable to use a wide monitor having a relatively wide width so that a sufficient view can be secured when a screen is divided.

Hereinafter, the constitution of each part of the present invention will be described in detail.

The first image input unit 110 receives the image signal of the internal network PC 10 and the second image input unit 120 receives the image signal of the external network PC 20. For example, The first image input unit 110 receives an analog image, and the second image input unit 120 receives a digital image. For example, the first image input unit 110 is connected to a D-SUB cable, and the second image input unit 120 is connected to a DVI cable, and the video signal of the internal network PC 10 and the external network PC 20 are connected to each other. Respectively.

The screen selection input unit 140 may receive an image corresponding to the screen area and the screen area through an On Screen Display (OSD) button for setting a monitor environment, As shown in FIG.

When the OSD button on one side of the monitor is used, a screen selection button for selecting a full screen or a split screen, which is the screen area, and a button for selecting a resolution may be further provided.

When the screen area and the resolution are inputted through the internal network or the external network PC 10 or 20, the user can directly set the screen area and the resolution, or the resolution automatically set when the operating system is operated.

The screen information transferring unit 190 transfers the screen resolution to the screen resolution memory unit 150 in the case where the full screen or the divided screen is selected in the screen selection input unit 140 or the resolution is changed, And delivers it to the internal network PC 10 and the external network PC 20.

More specifically, when a monitor is connected to a PC, EDID (Extended Display Identification Data) information containing information such as a displayable resolution of the monitor is transmitted to the PC. The PC transmits the image of the resolution appropriate to the monitor to the monitor.

The screen information transfer unit 190 delivers the EDID containing the optimized resolution for each divided area to the internal network PC 10 and the external network PC 20, as well as the EDID for the monitor itself.

Without the function of the screen information transfer unit 190, a monitor having a partition function can not deliver the EDID of each partitioned screen to the PC. Therefore, the resolution optimized for the divided screen is not realized, but the resolution built in the PC can be simply enlarged and displayed.

Therefore, when the user changes the divided screen through the screen selection input unit 140 in the normal mode used as the full screen in the resolution adjustment, the resolution optimal to the user or used immediately before is inserted into the monitor 100 The resolution of the divided screen can be automatically adjusted by loading the user resolution stored in the screen setting memory unit 150. [ If there is no resolution stored in the memory unit 150, the resolution is automatically adjusted to a resolution optimized for the divided screen ratio. Of course, you can arbitrarily change the resolution at any time if you want to change to a different resolution.

The video selector 130 selects a video signal input through the first and second video input units 110 and 120 to be output as a full screen or a divided screen according to a control signal of the monitor controller 160. [

That is, under the control of the monitor control unit 160, either one of the video signal of the internal network PC 10 and the video signal of the external network PC 20 input through the first and second video input units 110 and 120 Or synthesizes the video signal of the internal network PC 10 and the video signal of the external network PC 20 so as to be outputted simultaneously according to the split screen.

The monitor control unit 160 transmits the screen area and / or resolution information input from the screen selection input unit 140 and the resolution information stored in the screen setting memory unit 150 to the screen information transfer unit 190, the video selector 130 And transmits the synthesized image to the image display unit 170. The image display unit 170 displays the synthesized image.

That is, a screen area and a resolution stored in the screen setting memory unit 150 are selected using the screen area input from the screen selection input unit 140, and the selected screen area and resolution information are transmitted to the screen information transfer unit 190 To the video selector (130). As a result, the image selector 130 is controlled to select a screen region, and an image is output according to the resolution set by the image display unit 170.

In the screen setting memory unit 150, a screen area is divided into a full screen and a divided screen, and a resolution corresponding to each screen area is stored. Therefore, the optimum resolution according to the full screen and the divided screen is stored as a default value. At this time, the divided screen can be set differently in size and resolution depending on the ratio. For example, in the split screen, the ratio between the internal network screen and the external network screen is set to 1: 1, but the resolution of the internal network screen and the external network screen can be set differently. Of course, the split screen may be set such that the aspect ratios of the internal network screen and the external network screen are set asymmetrically such that the ratio of the internal network screen to the external network screen is 1: 2 or 2: 1, You can also set the resolution differently.

In the screen setting memory unit 150, the optimized resolution according to the full screen and the divided screen of the monitor is stored as a default value. This enables the automatic resolution optimization when the information on the screen area is inputted through the screen selection input unit 140 in the future.

The monitor control unit 160 updates the screen area and resolution stored in the screen setting memory unit 150 when a new screen area and resolution are input through the screen selection input unit 140. [

Hereinafter, a setting example of a screen division monitor dedicated for physical network separation according to the present invention will be described with reference to FIG. 1 and FIG.

When the monitor 100 connected to the internal or external network PCs 10 and 20 is turned on, the video signals of the internal network and the external network PCs 10 and 20 are received through the first and second video input units 110 and 120 (Sl)

In this case, the monitor control unit 160 controls the video selector 130 according to whether the screen area is a full screen or a divided screen, according to the screen area and the resolution stored in the screen setting memory unit 150, And outputs an image according to the resolution set by the display unit 170.

That is, after step Sl, the monitor control unit 160 compares the information on the screen area with information related to the screen area through the screen selection input unit 140 to determine whether the information is related to the divided screen. (S2)

If the information about the screen area is divided screen in step S2, the video selector 130 is controlled so that the video signal of the internal network PC 10 and the video signal of the external network PC 20 are simultaneously output (S3)

After step S3, the monitor control unit 160 determines whether the resolution of the divided screen input through the screen selection input unit 140 is automatically set by referring to the screen area and resolution stored in the screen setting memory unit 150 do. (S4)

If the resolution of the divided screen is automatically set through the step S4, the resolution is set by matching the optimized resolution (S5). If the resolution is not set automatically, the user operates the screen to input the resolution through the screen selection input unit 140 Manually set the resolution of the split screen. (S6) At this time, the resolution set by the user through the step S6 is stored in the screen setting memory unit 150. [

After the step S5 or step S6, the video signal of the internal network PC 10 and the video signal of the external network PC 20 are output in a divided screen according to the resolution set by the video display unit 170. [ (S7)

If the information about the screen area is full screen (S8), the entire screen input through the screen selection input unit 140 is a video signal of the internal network PC 10 or an external network PC 20) (S9)

The video signal of the selected internal network PC 10 or the video signal of the external network PC 20 is transmitted to the internal network PC 10 as a divided screen in accordance with the resolution set by the video display unit 170, And the video signal of the external network PC 20. (S10)

3 is a view showing a second embodiment of the present invention.

The monitor 100 includes a keyboard and mouse data input unit 180 capable of receiving mouse and keyboard data from the first terminal 10 and a keyboard and mouse data input unit 180 input through the keyboard and mouse data input unit 180. [ A keyboard and a mouse control unit 182 for determining whether the data of the first terminal 20 or the second terminal 20 is data of the first terminal 20 or the second terminal 20, A keyboard and mouse data output unit 184 for transmitting keyboard and mouse data to the keyboard and mouse data input unit 180 and a keyboard and mouse memory unit 186 for storing keyboard and mouse data input through the keyboard and mouse data input unit 180 do.

The first terminal 10 is an internal network PC and the second terminal 20 is an external network PC connected to the external network, as described above.

The keyboard and mouse data input unit 180 and the keyboard and mouse data output unit 186 are communicably connected to the first and second terminals 10 and 20, respectively. For example, a USB port, and is connected to the first terminal 10 and the second terminal 20 through a USB cable.

According to this configuration, the keyboard and mouse control unit 182 determines whether the keyboard and mouse data of the internal network PC 10 input through the keyboard and mouse data input unit 180 is a signal of the internal network screen area, And transmits the keyboard and mouse data to the external network PC 20 when it is selected as a signal in the external network screen area. This is because the keyboard and the mouse are connected only to the internal network PC 10 and the external network PC 20 is controllable even if a keyboard and a mouse are not separately provided.

Of course, a keyboard and a mouse may be connected only to the external network PC 20, and a keyboard and a mouse may not be separately provided to the internal network PC 10.

Data can be copied between the internal network PC 10 and the external network PC 20 through the keyboard and mouse memory unit 186. This is possible up to the network connection solution through the monitor 100 and configures the corresponding function to operate only in the administrator mode having limited authority. When the user requests to copy text data or an image in the Internet window of the external network through the "Ctrl + C" operation among the divided screens, the user temporarily stores the text data or the image in the keyboard and mouse memory 186, By performing "Ctrl + V" operation in the window, it is possible to minimize the work efficiency due to network separation by using the temporary clipboard function in the physical network separation situation.

In addition, the user of the internal network PC 1010 pre-registers the mobile phone 1020 in the monitor so that the mobile phone 1020 can not be connected to the network other than the authenticated mobile phone 1020 and the authenticated mobile phone 1020, So that it is possible to make a perfect transition. It is preferable to reduce the cost of introducing a device for authenticating the user's log when the mobile phone 1020 is connected to the external network through the pre-authentication of the mobile phone 1020.

The screen selection input unit 1140 receives an input of a screen area and a resolution through the OSD (On Screen Display) button for setting the monitor environment, or receives the input through the internal network PC 1010 or the cellular phone 1020.

In this case, when the OSD button on one side of the monitor is used, it is possible to select the full screen, the divided screen or the optimal resolution which is the screen area.

When the screen area and the resolution are inputted through the internal network PC 1010 and the mobile phone 1020, the user can directly set the screen area and the resolution, or the resolution automatically set when the operating system is driven.

The screen information transfer unit 1190 transfers the resolution corresponding to each screen in the screen setting memory unit 1150 when the full screen or the divided screen is selected or the resolution is changed in the screen selection input unit 1140 And delivers it to the internal network PC 1010 and the cellular phone 1020.

More specifically, when a monitor is connected to a PC, extended display identification data (EDID) information including information such as a displayable resolution of the monitor is transmitted to the PC. The PC transmits the image of the resolution appropriate to the monitor to the monitor.

The screen information transmitting unit 1190 delivers the EDID containing the optimized resolution for each divided area to the internal network PC 1010 and the cellular phone 1020, as well as the EDID for the monitor itself.

Without the function of the screen information transfer unit 1190, a monitor having a partition function can not deliver the EDID of each partitioned screen to the PC. Therefore, the resolution optimized for the divided screen is not realized, but the resolution built in the PC can be simply enlarged and displayed.

The image display unit 170 displays the synthesized image.

In the screen setting memory unit 1150, a screen area is divided into a full screen and a divided screen, and a resolution corresponding to each screen area is stored. Therefore, the optimum resolution according to the full screen and the divided screen is stored. At this time, the divided screen can be set differently in size and resolution depending on the ratio. For example, in the split screen, the ratio of the internal network screen and the external network screen is set to 1: 1, but the resolution of the computer screen and the mobile phone screen can be set differently. Of course, the split screen may be set asymmetrically such that the ratio of the computer screen to the mobile phone screen is 1: 2 or 2: 1, or the mobile phone screen may be set as the sub screen and the resolution of the computer screen and the mobile phone screen may be set differently have.

In addition, the screen setting memory unit 1150 stores the optimized resolution according to the full screen and the divided screen of the monitor as default values. This enables the automatic resolution to be automatically set when information on the screen area is inputted through the screen selection input unit 1140 in the future.

The monitor control unit 1160 updates the screen area and the resolution stored in the screen setting memory unit 1150 when the screen area and the resolution are inputted through the screen selection input unit 1140.
