Fig. 2A is a schematic diagram of a system for multi-screen display according to the present embodiment. Referring to fig. 2A, the system includes: a host 100 and a multi-screen system 200 in communication with the host 100 (e.g., via a video transmission cable). The multi-screen system 200 includes a primary screen 210 and secondary screens 221-226. The multi-screen display system 200 may be, for example, a computer device provided for financial staff, thereby providing a multi-screen data display function for the staff. The primary screen 210 may be, for example, a display screen facing the staff member, so that the primary screen may be used to view a primary interface of the data analysis software, and the secondary screens 221-226 may be, for example, displaying data forms of different subjects, so that the staff member can view more data. (note: the primary screen 210 and the secondary screens 221-226 described in this embodiment are merely illustrative of the primary screen 210 being the display screen facing the worker; in particular, the primary screen 210 and the secondary screens 221-226 may be separate and flat displays from each other; the secondary screens 221-226 may be displayed independently of the primary screen 210, that is, the secondary screens 221-226 may be displayed even if the primary screen 210 is not displayed).

Further, fig. 2B shows a program architecture diagram of an application program provided in the host 100, and referring to fig. 2B, a main program process is a main framework process of an application program running in the host 100, and functions performed include: 1) Corresponding operation in the starting and closing processes of the application program; 2) Interaction with a worker (e.g., interaction triggered by a mouse or other means); 3) Performing data processing; 4) And calling a display process to display on each display screen. The host 100 is provided with a plurality of display processes 0 to 6 corresponding to the display screen 210 and the display screens 221 to 226. Specifically, the display processes 0 to 6 are used for performing operations such as data transmission, rendering, display and the like related to display, and the main program process performs corresponding display functions of the display screens 210, 221 to 226 by mobilizing the display processes 0 to 6.

It should be noted that, the host 100 and the multi-screen display system 200 in the system may be applicable to the hardware structure described in fig. 1.

In the above-described operating environment, according to the first aspect of the present embodiment, there is provided a method of multi-screen display applied to a host capable of implementing multi-screen display, the method being implemented by the host 100 shown in fig. 2A. Fig. 3 shows a schematic flow chart of the method, and referring to fig. 3, the method includes:

S302: creating a plurality of display processes respectively associated with a plurality of display screens, wherein the plurality of display screens are in communication connection with a host; and

s304: rendering and displaying on the plurality of display screens by invoking at least one of the plurality of display processes.

As described in the background art, the existing multi-screen display system generally uses a single process to display on multiple display screens, so that the following problems exist: when an operation on one display causes a process to crash, content on the other display may also restart due to the process crashing.

In view of this, the present embodiment provides a multi-screen display method, in which, in the case where the user needs to perform data display and analysis through a plurality of display screens, the main program process of the host 100 can create a plurality of display processes (i.e., display process 0 to display process 6) respectively associated with the plurality of display screens 210 and 221 to 226 when the application is started, for example (S302). Specifically, referring to fig. 2A, for example, the currently opened display screen is the main screen 210 and the sub screens 221 to 226 connected to the host 100, and referring to fig. 2B, the host 100 may create a plurality of display processes 0 to 6 corresponding to the main screen 210 and the sub screens 221 to 226 through the main program process. Wherein the plurality of display processes 0 to 6 are sub-processes of the main program process on the host 100, and the plurality of display processes 0 to 6 are invoked through the main program process. So that the main program process renders and displays on the main screen 210 and the sub-screens 221 to 226 by calling at least one of the plurality of display processes 0 to 6. For example, when a main program process on the host 100 is started, it first checks which display screens connected to the host 100 are started, and identifies the corresponding started display screen, and for the already started display screen, it invokes the corresponding display process to perform rendering display operation related to the component on the display screen. Therefore, the display modes of the display screens are respectively rendered by multiple processes, the display of the components triggered by each display screen can be independent, and even if the display process corresponding to one display screen is crashed or needs to be stopped due to some reasons, other processes are not prevented from continuously displaying the components triggered by the corresponding display screen. Therefore, the technical problem that in the prior art, when the operation on one display screen causes the process to crash, the content on other display screens can be restarted due to the process crash is solved.

Optionally, the method further comprises: responding to a first triggering operation of a user, and determining a first display screen corresponding to a target object of the first triggering operation, wherein the first display screen is associated with a first display process; according to the first triggering operation and the target object, determining a first component to be displayed and a second display screen for displaying the first component, wherein the second display screen is associated with a second display process, and the first display process and the second display process are different display processes; and displaying the first component on the second display screen through the first display process.

As described in the background art, the existing multi-screen display system generally displays data information of different software on different display screens or displays the data information on a plurality of display screens by adopting a single process, and has the following problems: in the existing multi-screen display system, data information of different software is usually displayed on different display screens, so that linkage between the different display screens cannot be realized.

Referring to fig. 4A, each of display processes 0 to 6 is configured to render and display a component triggered on a display screen corresponding to the display process. For example, a component that triggers to display on display screen 210 is rendered and displayed by display process 0 corresponding to display screen 210. And, even in the case of dragging the component from display 210 to other displays (e.g., display 221), the component is still rendered and displayed by display process 0. Further, a component 310 is displayed on the home screen 210, wherein the component 310 is displayed, for example, by a user triggering a display by clicking a predetermined button on an interface displayed on the home screen 210. The component 310 is rendered and displayed by the main program process by invoking display process 0. Also, a component 320 is displayed on the sub-screen 221, wherein the component 320 is displayed, for example, by a user clicking a predetermined button on an interface displayed on the sub-screen 221. The component 320 is rendered and displayed by the main program process by invoking display process 1. Therefore, the display mode that a plurality of display processes respectively render a plurality of display screens is realized.

Further, the host 100 determines, in response to a first trigger operation of the user, a first display screen corresponding to a target object of the first trigger operation, where the first display screen is associated with a first display process. Wherein the target object may be a component on the first display screen. For example, the user triggering the first display screen (which may be, but is not limited to, the main screen 210, and the first display screen 210 is hereinafter used as an explanation) may be a component on the main screen 210, and the first display process that the host 100 may call through the main program process may be the display process 0.

Further, the host 100 determines, according to the first trigger operation and the target object, a first component to be displayed and a second display screen for displaying the first component, where the second display screen is associated with a second display process, and the first display process and the second display process are different display processes. Wherein the first component is a component triggered on the first display screen, and therefore, no matter on which display screen the first component is displayed, the first component is displayed and rendered through a first display process corresponding to the first display screen.

Specifically, referring to fig. 4B, for example, when a worker drags a component 310 on the main screen 210 (first display screen) to the sub-screen 221 (second display screen) through a mouse, and thus when the sub-screen 221 displays a component 310 '(i.e., a first component) corresponding to the component 310, the main program process still displays the component 310' by invoking the display process 0, although the component 310 'is displayed on the sub-screen 221, since the component 310' is triggered at the main screen 210. And in this case, when the main program process needs to update the data information in the component 310 displayed by the main screen 210 and the component 310' displayed by the sub-screen 221, the updated component 310 and the component 310' can be rendered by calling the same display process 0, so that the linkage of the component 310 and the component 310' in different screens is realized.

That is, in this embodiment each display has an associated display process. The meaning of "associated" is further based on "first trigger" in the display. For example, since 310' is a component window generated based on a trigger of component 310 in home screen 210 (with respect to "first time" in "first time trigger", explained in detail below), the component window is rendered and displayed by first display process 0 associated with first display screen 210 even though it is not displayed in first display screen 210. For other display screens and associated display processes, and so on.

Thus, in this manner, the main program process does not have to reassign the display process to the component 310 even if the component is dragged to any other display screen. And because component 310 is displayed by the same display process 0 as home screen 210, even though components 310 are located on different display screens than components within home screen 210, the display and updating can be performed by the same process. Referring to fig. 4B, although the component 310' (first component) is displayed on the sub-screen 221, it is not necessary to display using the display process 1 corresponding to the sub-screen 221, but it is displayed through the display process 0 corresponding to the main screen 210 (first display screen). Therefore, the data to be displayed only need to be sent to the same display process, the data do not need to be sent to two display processes, and the data are not required to be transmitted between the two display processes, so that the multi-screen linkage is facilitated.

Further, the host 100 displays the first component on the second display screen through the first display process. Referring to fig. 4B, for example, the user may drag the component 310 on the primary screen 210 to the corresponding component 310' (first component) displayed on the secondary screen 221 (second display screen) by way of a drag. So that the host 100 can display the first component (component 310') on the sub-screen 221 by calling the display process 0 through the main program process.

That is, the association between a display process and a display screen described in the present invention is not embodied in rendering a display by a display process on an associated display screen, but rather in rendering and displaying a component by a display process associated with a display screen when a trigger is made on one display screen and thus the component is required to be displayed upon the trigger.

For example, when a pop-up component is displayed by clicking a button on the home screen 210, the pop-up component is rendered and displayed by invoking display process 0 associated with the home screen 210, no matter on which screen the pop-up component is displayed. Similarly, when a pop-up component is displayed, for example, by a triggering operation made on the sub-screen 221, no matter on which screen the pop-up component is displayed, it is rendered and displayed by invoking the display process 1 associated with the sub-screen 221, and so on.

Thus, in the above manner, the host 100 creates display processes corresponding to the plurality of display screens through the main program process, renders and displays the components on the display screen through the display processes corresponding to the display screens, and displays and renders the components triggered on the display screen through the display processes corresponding to the display screens, regardless of which display screen is displayed on. Therefore, the technical effect that the independent operation of the multi-screen linkage and the display process can not generate interference is achieved. And further solves the technical problem that the existing multi-screen display system in the prior art cannot realize linkage among a plurality of display screens.

Optionally, the operation of creating a plurality of display processes respectively associated with the plurality of display screens includes: identifying a plurality of display screens in an on state from the display screens in communication with the host; and creating a plurality of display processes respectively associated with the plurality of display screens in the on state.

Specifically, referring to fig. 2A and 2B, first, the host 100 may identify a plurality of display screens in an on state from among display screens (e.g., the multi-screen display system 200 shown in fig. 2A) communicatively connected to the host 100 through a main program process. The host 100 may then create a plurality of display processes associated with the plurality of display screens in the on state, respectively, with the main program process. For example, in the case where the main screen 210 and the sub screens 221 to 222 in fig. 2A are turned on and the sub screens 223 to 226 are turned off, the main program process can recognize that the main screen 210 and the sub screens 221 to 222 are in the on state, thereby creating display processes 0 to 2 corresponding to the main screen 210 and the sub screens 221 to 222. By the mode, a corresponding display process is allocated for the opened display screen. Thus, components on different display screens are displayed by multiple display processes, and components on the same display screen are displayed by the same display process. Therefore, linkage among the display screens is achieved, and the display processes of the display screens independently run without interference.

Optionally, in response to a first trigger operation of a user, determining an operation of a first display screen corresponding to a target object of the first trigger operation includes: in response to a first trigger operation of a user on a second component, determining a first display screen for displaying the second component, and determining the first component to be displayed and the operation for displaying the second display screen of the first component according to the first trigger operation and the target object, including: according to the first triggering operation, a first component and a second display screen which are associated with the second component are determined.

Specifically, referring to fig. 4B, the host 100 determines a first display screen (e.g., the home screen 210 in fig. 4B) on which to display a second component (e.g., the component 310 in fig. 4B) in response to a first trigger operation of the second component by a user. Wherein for example the user may trigger a component on the first display screen by clicking the mouse. The host 100 then determines a first component (component 310') associated with the second component (component 310) and a second display screen (sub-screen 221) according to the first trigger operation. Wherein the first triggering operation may be, for example, that the user drags the second component (component 310) on the first display screen (the main screen 210) to the second display screen (the sub screen 221) by way of dragging, to display the first component (component 310') corresponding to the second component. Thus, by the above manner, the main program process of the host 100 can determine the first component to be displayed, the display screen of the first component to be displayed, and the display process for displaying the first component, so that the main program process is facilitated to display the first component on the second display screen by calling the first display process.

Optionally, the present embodiment further includes: responding to a second triggering operation of the user on the first component, determining a third component to be displayed and a third display screen for displaying the third component, wherein the third display screen is associated with a third display process; and displaying the third component on the third display screen through the first display process.

Specifically, referring to fig. 4C, the host 100 may determine the component 310 "(i.e., the third component) to be displayed and the display screen 226 (i.e., the third display screen) for displaying the component 310″ in response to a second trigger operation of the component 310' (i.e., the first component) by the user, wherein the display screen 226 and the display process 6 (i.e., the third display process) are associated. Wherein the second triggering operation may be a user dragging the component 310' on the display screen 221 to drag onto the display screen 226 for display. The host 100 then still displays the component 310 "on the display screen 226 by displaying process 0 (i.e., the first display process). That is, in this scenario, the meaning of "first" in "first trigger" in this embodiment is explained. Although component 310 "is generated based on the user's triggering operation of component 310' on display 221, component 310' is generated based on the first triggering operation of component 310 on display 210. The solution of the present embodiment therefore does not display and render component 310 "by display process 1 associated with display screen 221, but rather still uses display process 0 associated with display screen 310 to display and render component 310".

Wherein the first component is also a component on the first display screen, and is displayed on the second display screen only, because the first component is displayed by the triggering operation of the second component on the first display screen. Therefore, when the user drags the first component on the second display screen to display the third component on the third display screen, the third component is still a component of the first display screen, so that the host 100 still calls the first display process corresponding to the first display screen to display the third component. Therefore, three different components can be displayed on three different display screens only by calling the first display process, data transmission to a plurality of display processes is avoided, data transmission among the display processes is not needed, and linkage of the first component, the second component and the third component in the different display screens is more convenient to realize. For other display screens and associated display processes, and so on.

Optionally, the present embodiment further includes: determining data information to be displayed; and synchronously displaying the data information on the first component and the second component through a first display process.

Specifically, referring to fig. 4B, first, the host 100 determines data information to be displayed, which may be, for example, a time-sharing diagram for displaying stock information. The host 100 then synchronously displays the data information at the first component and the second component through the first display process. The first component (component 310') is a component displayed on the second display screen by a first trigger operation of the user on the second component (component 310) on the first display screen (main screen 210), so the first component is also displayed by the first display process corresponding to the first display screen. So that in the event that the host 100 determines data information to be displayed on the second component, the host 100 may invoke the first display process to synchronously display the same data information on the first component and the second component. By the method, the same components (namely the first component and the second component) are displayed on different display screens due to triggering operation of a user, so that the same data content is displayed on the same components on different display screens.

Optionally, the present embodiment further includes: presetting a first form, wherein the first form comprises component display information corresponding to the displayed components respectively, and the component display information comprises the following information of the corresponding components: triggering display screen information of a display screen corresponding to triggering operation of the corresponding component; display progress information for displaying a display progress of the corresponding component; and display screen information for displaying the display screen of the corresponding component.

Specifically, referring to table 1, a user may preset a first form through the host 100, wherein the first form includes component display information corresponding to the displayed components, respectively, and the component display information includes the following information of the corresponding components: display screen information of the display screen corresponding to the triggering operation of the triggering corresponding component, for example, the content of the triggering point corresponding to the content of the triggering point in table 1 and the triggering point of the component 1 with the number 001 are on the main screen 210. Display progress information for displaying a display progress of a corresponding component, for example, a corresponding allocation display progress in table 1, that is, a start point of component 1 of number 001 is on the home screen 210, and a display progress corresponding to the home screen 210 is display progress 0. The display screen information for displaying the display screen of the corresponding component corresponds to the current display screen in table 1, in which the user can drag the component to other display screens except the display screen of the trigger point of the component for displaying, for example, the display screen of the trigger point of component 2 in 002 number in table 1 is the main screen 210, but the display screen currently displayed is the sub screen 221. The host 100 thus displays a first form of information via the pre-set components, and the main program process can determine on which display screen each component is triggered and by which display process is displayed on that display screen by loading the above information when displaying the components.

TABLE 1

ID number	Component name	Trigger point	Assigned display process	Current display screen
					001	Assembly 1	Main screen 210	Display Process 0	Main screen 210
002	Assembly 2	Main screen 210	Display Process 0	Auxiliary screen 221
					003	Assembly 3	Auxiliary screen 221	Display process 1	Main screen 210
004	Assembly 4	Auxiliary screen 222	Display Process 2	Main screen 210
					...	...	...	...	...

Optionally, displaying, by the first display process, the operation of the first component on the second display screen includes: querying component display information corresponding to the second component in the first form; determining a first display process for displaying the first component according to the component display information; and displaying the first component on the second display screen through the first display process.

Specifically, referring to table 1, the host 100 first queries the first form for the component display information corresponding to the second component through the main program process in the process of displaying the operation of the first component on the second display screen through the first display process by using the main program process. The host 100 then determines a first display process for displaying the first component from the component display information using the main program process. And finally, the host computer displays the first component on the second display screen through the first display process. Wherein, for example, the ID number of the second component is 001, the trigger point of the second component found by the main program process in the first form is the main screen 210, and since the first component is a component that the user displays on the other display screen by triggering the second component, the main program process can determine that the first display process for displaying the first component and the display process of the second component are the same, that is, display process 0. The host 100 then displays the first component on the second display screen (i.e., the secondary screen 221) through the first display process (i.e., display process 0) using the main program process. Thus, in the above manner, the main program process can determine on which display screen each component is triggered and by which display process is displayed by loading the above information when displaying the components.

Optionally, the present embodiment further includes: a second form is preset, wherein the second form comprises component attribute information corresponding to the displayed components respectively, and the component attribute information is used for describing the attributes and functions of the corresponding components.

Specifically, for example, the host 100 may set a second form in advance, wherein the second form includes component attribute information corresponding to the displayed components, respectively, and the component attribute information is used to describe attributes and functions of the corresponding components. Then, referring to fig. 4B, in case that the user drags the second component 310 in the main screen 210 to the sub screen 221 to display the first component 310', the main program process may read the attribute and function with respect to the second component 310 from the second form and generate the first component 310' according to the read information. Thus, the first component 310 'inherits the attribute and function of the second component 310, and thus the same data content can be displayed by the first component 310' in the second display 221 and the second component 310 in the first display 210 through the first display process corresponding to the first display.

Optionally, displaying the operation of the first component on the second display screen further includes: querying component attribute information corresponding to a second component in a second form; determining component attribute information of the first component according to component attribute information corresponding to the second component; and displaying the first component according to the determined component attribute information.

Specifically, referring to fig. 4B, when the user drags a component in the current display screen (for example, the second component 310 in the main screen 210) to the other display screen (the first component 310' on the sub screen 221) to display, the host 100 first queries the second form for component attribute information corresponding to the second component. I.e. the host 100 may query the attribute information of the second component that the user needs to trigger. Then, the host 100 determines the component attribute information of the first component according to the component attribute information corresponding to the second component. Since the first component is a component that the user displays by triggering the second component, the first component inherits component attribute information and functions of the second component. Finally, the host 100 displays the first component according to the determined component attribute information. The host 100 may thus display the first component on the second display by triggering a first display process corresponding to the first display of the second component. In addition, since the first component is a component that the user displays by dragging the second component, all other properties are the same except for the position at which the first component and the second component are displayed. In this way, the host 100 can quickly generate the first component to be displayed by reading the second form, thereby improving the efficiency of the display operation.

Further, referring to fig. 5, for example, multi-screen linkage between different display processes can also be achieved in the following manner. A list of information about different stocks is displayed in a component 320 in the sub-screen 221, for example. The component 310 in the home screen 210 is used, for example, to display a time-share diagram related to a stock. When a worker selects stock 1 in the component 310, the main program process determines data information of the stock 1 selected by the worker in response to the trigger operation. The main program process then transmits information about stock 1 to the display process 0, and transmits data information for drawing a time chart to the display process 1. So that the time chart related to stock 1 and the information are rendered and displayed through the display process 0 and the display process 1, respectively. When the staff selects other stocks in component 310, the coordinated display of the two windows is also achieved in a similar operation. Thus, in this way, a coordinated display between components displayed on different screens and by different display processes can be achieved.

In addition, referring to fig. 6, each service module on the interface (each service module can display different subjects or service data in different forms according to different requirements) is independently arranged in a form of a component, so that a worker can drag out the service module in the interface, and can drag into different display screens. When a user drags a component of a certain service module on the interface, after the main program process perceives that the component is dragged out of the current interface of the user, the main program process can independently generate a new window to display the service module. Specifically, as shown in fig. 6, the interface 310 displayed on the main screen 210 of the multi-screen display system displays a plurality of components 311 to 314 of independent business modules. That is, the components 311 to 314 of the respective service modules can independently display data information. Specifically, as described in reference to the first embodiment, the main program process performs data processing and analysis, and after performing data processing, for example, the display process 0 may be invoked to render and display the interface 310 of the main screen 210 and the contents of the components 311 to 314 of the respective business modules.

When a worker wants to focus on the data information in the business module displayed by the component 311, the component 311 can be dragged with a mouse. And when the main program process determines that the component 311 has dragged out of the interface 310 (e.g., to the secondary screen 211), a new window 410 is generated. At this time, since the components in the window 410 and the components 311 are the same, the components in the window 410 inherit the properties and functions of the components 311, i.e., the same data information as the components 311 is displayed in the window 410. And because the window 410 is triggered at the interface of the home screen 210, the home program process associates the window 410 with display process 0, rendering and displaying the content of the window 410 by invoking display process 0. So that after updating the data in component 311, the main program process may render and display the updated data information in component 311 and window 410 simultaneously, for example, by displaying process 0.

Optionally, the first triggering operation is an operation of dragging the second component by a user, and determining, according to the first triggering operation and the target object, the first component to be displayed and an operation of displaying a second display screen of the first component, including: the first component is displayed on the second display screen in response to a user dragging the second component to the second display screen.

Optionally, determining the first component to be displayed and the operation of the second display screen for displaying the first component according to the first triggering operation and the target object includes: the first component is displayed on the first display screen in response to a user dragging the second component to the first display screen.

Specifically, the first trigger operation of the second component by the user may be an operation of dragging the second component, so that the first component may be displayed in a dragged position, where the first component inherits the component properties and functions of the second component. Thus, in response to a user's operation of dragging the second component to the second display screen, the host 100 displays the first component on the second display screen through the first display process. Or in response to a user's operation of dragging the second component to the first display screen, the host 100 displays the first component on the first display screen through the first display process. For example, referring to fig. 4B, in case that the user drags the second component 310 on the main screen 210 to the second display screen 221 to display the first component 310', the host 100 may display the first component 310' on the second display screen 221 through the first display process corresponding to the main screen 210. Further, although not shown in the figures, the user may drag the second component on the first display screen 210 to other locations of the current display screen 210 to display the first component 310'. So that the host 100 displays the first component through the first display process of the first display corresponding to the second component, no matter which display the second component is dragged to by the user to display the first component.

Further, referring to fig. 1, according to a second aspect of the present embodiment, there is provided a storage medium. The storage medium includes a stored program, wherein the method of any one of the above is performed by a processor when the program is run.

Thus, according to the present embodiment, the host 100 creates display processes corresponding to a plurality of display screens respectively through the main program process, renders and displays components on the display screen through the display process corresponding to the display screen, and displays and renders the components triggered on the display screen through the display process corresponding to the display screen regardless of the display screen on which the components are displayed. And because each display screen is distributed with independent display processes, the display of the components triggered by each display screen can be independent of each other through a multi-process display mode, and even if the display process corresponding to a certain display screen is crashed or needs to be stopped due to some reasons, other processes are not prevented from continuously displaying the components triggered by the corresponding display screen. Therefore, the technical effect that the independent operation of the multi-screen linkage and the display process can not generate interference is achieved. The method solves the technical problems that the existing multi-screen display system in the prior art cannot realize linkage among a plurality of display screens, and because the display is carried out on the plurality of display screens through a single process, all the display screens cannot display contents under the condition that the process is crashed.
