The present invention relates to a method of sharing data between monitors of dual monitors.

In general, a dual monitor has two LCD screens, and each of the two LCD screens outputs a different screen to enable multiple operations, or two LCD screens output the same screen to display the same screen with others. It can be used in banks, securities firms, government offices, libraries, hospitals, and other places where customer consultations are performed.

Usually, such dual monitors are installed with two screens facing in opposite directions as shown in FIG. The dual monitor allows the conversation to proceed while viewing the same screen, and is showing great use in consultation centers in financial fields such as civil service consultation counters in banks, banks, and offices and reception desks in hospitals.

This dual monitor is to install a dual graphics card in the PC to output each video output of the dual graphics card on both screens of the dual monitor.

However, when using dual monitors, it is easy to switch between sharing the output screens from these dual monitors while using the computer in a computer environment using dual graphics cards when the counselor and the consultant need to see the same screen. As a result, the output screens of both monitors were identically output from the basic initial stages, or the output screens between the two monitors were adjusted by hardware manipulation, which caused a lot of inconvenience in actual use.

Therefore, even though the dual screen outputs the same screen and repeatedly controls to output different screens, there is no specific technology development despite the very necessary functions due to the characteristics of the actual environment of the dual monitor.

The present invention has been made to solve the above problems, the object of which is to maximize the utilization of dual monitors by allowing two monitors to share the output screen with each other in a dual monitor integrated two monitors. It provides a way to share data between monitors of dual monitors.

In addition, the dual monitor's master monitor and the sub-monitor share the output screen with each other, while when displaying the master monitor's screen as a sub-monitor masking processing to achieve customer information security data sharing method between the dual monitors To provide.

Characterized in that it comprises a.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

The present invention below is a preferred embodiment of the data sharing method between the monitors of the dual monitors to maximize the utilization of the dual monitors by allowing the two monitors to share the output screen with each other in the dual monitors are integrated monitors It will be described as, but the technical idea of the present invention is not limited to this, but can be variously modified and implemented by those skilled in the art.

2 is a conceptual view illustrating a data sharing method between monitors of a dual monitor according to an exemplary embodiment of the present invention.

As shown in FIG. 2, the dual monitor 10 of the present invention basically receives an image through the dual graphic card 20 having two image output ports and outputs the corresponding image.

The first image output module 20a of the dual graphics card 20 outputs a first screen to the master monitor 10a of the dual monitor 10, and also outputs a second image of the dual graphics card 20. The module 20b outputs the second screen to the sub-monitor 10b of the dual monitor 10.

Here, the control unit 30 of the present invention outputs the first screen output from the first image output module 20a to the second image output module 20b upon the user's request, so that the output screen of the master monitor serves simultaneously. It also outputs to the monitor.

In addition, the second screen output from the second image output module 20a may be output to the first image output module 20a so that the output screen of the sub monitor is simultaneously output to the master monitor.

Here, screen copying between the master monitor 10a and the sub-monitor 10b of the dual monitor 10 is made according to a user's request, and the user's request is input through the input unit 50 to control the corresponding controller ( 30) become aware. In this case, the input unit 50 is a keyboard or a mouse which is a general computer input device.

When the controller 30 receives a master output screen sharing command from the user through the corresponding input unit 50, the controller 30 stores the real-time output image data of the first image output module 20a in charge of the master monitor 10a. 40 is temporarily stored in the first image storage unit 40a. The control unit 30 extracts the image data of the first image storage unit 40a stored in this way and delivers the image data to the second image output module 20b in real time, thereby outputting the first image output module 20a and the second image output. The module 20b outputs the same image data so that the master monitor 10a and the sub-monitor 10b can display the same image.

In this case, the first image storage unit 40a is a temporary buffer, and the output image data of the first image output module 20a stored in the first image storage unit 40a is stored in chronological order. The first stored image is inputted and outputted by a first-in first-out (FIFO) mechanism.

Of course, in addition to the master output screen sharing command for displaying the output screen of the master monitor 10a described above on the sub monitor 10b, the sub screen for displaying the output screen of the sub monitor 10b on the master monitor 10a in the same manner. Output sharing command is also available.

That is, when the control unit 30 receives a sub output screen sharing command from the user through the corresponding input unit 50, the control unit 30 stores the real time output image data of the second image output module 20b that is in charge of the sub monitor 10b. The second image storage unit 40b of the unit 40 is temporarily stored. The control unit 30 extracts the image data of the second image storage unit 40b stored in this way and delivers the image data to the first image output module 20a in real time, thereby outputting the second image output module 20b and the first image output. The module 20a outputs the same image data so that the sub-monitor 10b and the master monitor 10a can display the same image.

On the other hand, the sub-monitor 10b in which the guest views all the screen contents of the master monitor 10a, which the employee views, according to the characteristics used in the environment in which the dual monitor 10 faces each other and conducts a conversation for consultation. It is often crowded to show.

In this case, the user (for example, the counselor) inputs a masking command to display the sub-monitor 10b in a state of masking a part of the output screen of the corresponding master monitor 10a as shown on the left side of FIG. do.

That is, the image of the master monitor 10a stored in the first image storage unit 40a is output to the sub monitor 10b, and at least one opaque mask layer, which is sized by the user, is added to the corresponding screen. By outputting to the monitor 10b, the screen of the master monitor 10a can be shared with the sub-monitor 10b while screen filtering is performed to secure various types of information.

In addition, when the user shares the screen of the master monitor 10a with the sub-monitor 10b at the briefing, a graphic brush work is performed through the screen editing module 60 so that the master monitor 10a and the sub-monitor 10b of You can edit the shared output screen.

In this case, the user (for example, the briefing staff) inputs a screen editing command and performs a graphic brush operation such as drawing a pen on the output screen of the corresponding master monitor 10a as shown on the left side of FIG. 4. The screen can be shown at 10b.

That is, the image of the master monitor 10a stored in the first image storage unit 40a is output to the sub monitor 10b, and the controller 30 controls the master monitor 10a through the screen editing module 60. Brush color created by displaying the color and type selection window of the brush to create, receiving graphic brush creation information composed by user's mouse movement, and setting the brush file composed of the graphic brush creation information as the highest priority. By adding to the screen to output to the sub-monitor (10b) it is possible to be efficient briefing work using the dual monitor.

Now, a method of sharing data between monitors of a dual monitor according to an exemplary embodiment of the present invention will be described with reference to FIG. 5.

First, the controller 30 is in a standby state, that is, the master monitor 10a and the sub monitor 10b through the first image output module 20a and the second image output module 20b of the dual graphics card 20. Each image is outputted to each other so that the first image output module 20a and the second image output module 20b of the corresponding dual graphics card 20 operate independently (S10).

Thereafter, the controller 30 determines whether a screen sharing command for requesting screen sharing between dual monitors is received from the user through the input unit 50 (S12).

In this case, the screen sharing command may be a master screen sharing command for sharing the screen of the master monitor to the sub-monitor and a sub screen sharing command for sharing the screen of the sub-monitor to the master monitor.

In the following description, a case in which a master screen sharing command for outputting and sharing the same screen of the master monitor to the sub-monitor is given will be described. However, the present invention is not limited thereto.

As a result of the determination in step S12, when a screen sharing command (eg, a master screen sharing command) between the dual monitors is received from the user, the controller 30 reads the output image data of the first image output module 20a. The first image storage unit 40a is stored in operation S14.

At this time, the output image data of the first image output module 20a stored in the first image storage unit 40a is stored in chronological order so that the first stored image is output first, first-in first-first. input / output through the mechanism of out).

Next, the controller 30 extracts the output image data of the first image output module 20a stored in the first image storage unit 40a and delivers the output image data to the second image output module 20b in real time. The second image output module 20b supports to output the same image as the image output from the master monitor 10a to the sub monitor 10b (S16).

Therefore, all the work screens worked through the master monitor 10a occupied by the first image output module 20a are simultaneously copied to the sub monitor 10b through the second image output module 20b in real time. Will be displayed.

Of course, the screen sharing between the master monitor 10a and the sub-monitor 10b not only outputs the screen of the master monitor 10a but also the sub-monitor 10b outputs the screen of the sub-monitor 10b. It is also possible to output the same as 10a.

Subsequently, the control unit 30 performs a security masking command for the security of the screen of the sub-monitor 10b that displays the same screen of the master monitor 10a according to the screen sharing between the dual monitors from the user through the input unit 50. It is determined whether or not it has been received (S18).

As a result of the determination in step S18, when a security masking command is received, the controller 30 receives setting information on the size and display position of at least one or more opaque mask layers from the user through the input unit 50. (S20).

Thereafter, the controller 30 outputs the output image of the master monitor 10a side stored in the first image storage unit 40a to the sub monitor 10b, and the opacity mask layer designated by the user has the highest priority. In the set state, the corresponding opacity mask layer is output to the second image output module together with the stored output image of the master monitor side so that the output screen is covered by the sub monitor in operation S22.

As a result, when two monitors face each other between the operator and the customer, the shared screen can be selectively masked according to the security function when the screen of the operator is shared through other monitors. This allows the operator to selectively mask the screen that should not be shown to the user.

On the other hand, when the screen editing command other than the security masking command is received as a result of the determination in step S18 (S24), the controller 30 inputs the input unit 50 for the screen briefing by the corresponding user through the screen editing module 60. Supports brush drawing input using) and receives brush creation information according to at least one brush operation (S26).

Subsequently, the controller 30 outputs the output image of the master monitor 10a stored in the first image storage unit 40a to the sub monitor 10b, and sets the brush pieces created by the user as the highest display order. By transmitting the stored image to the second image output module together with the output image of the master monitor side, the corresponding brush piece is output in a state of covering the output screen in the sub-monitor (S28).

In this case, the above-described security masking process may be displayed together with the master screen on the sub-monitor at the same time as the screen sharing while the size and position of the screen is previously specified by the user who is watching the master monitor before the screen sharing.

Subsequently, the main controller 30 determines whether a screen return command for stopping screen sharing between the dual monitors is received from the user through the corresponding input unit 50 (S30). The storage of the output image of the image output module 20a is stopped, and the function of the second image output module 20b on the sub monitor 20b side is restored (S32).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited to drawings.

As described above, in the dual monitor image sharing method of the present invention, two monitors are integrated in a dual monitor so that two monitors can share the output screen with each other, thereby maximizing utilization of the dual monitor. It is effective.

In addition, dual monitor master monitor and sub monitor share output screen with each other, and when user's screen is shown through other monitor, the shared screen can be selectively masked according to security function. It also has the effect of providing information security by allowing the operator to selectively mask the screen to be done.
