[0046] The embodiments of the present application provide a split-screen display method and device thereof, which are used to improve the convenience of split-screen display of dual system images and improve the user experience.

[0047] The conference tablet all-in-one includes two hardware systems: an Android development board and an open pluggable specification (OPS) microcomputer running Windows connected to the Android development board. OPS is a standardized digital signage interface specification jointly developed by Intel and display manufacturers. The internal structure of OPS is a mini personal computer with an X86 architecture, using an Intel Core processor, equipped with memory, hard disk, multiple input and output interfaces, and a Windows operating interface. With the support of two hardware systems, the conference tablet all-in-one can display the images of two systems on the same screen.

[0048] See also Figure 1 , an embodiment of the split-screen display method provided by the present application includes:

[0049] 101. The first operating system starts a target split-screen application.

[0050] When it is necessary to display the screens of the two systems in split screen, the user clicks the icon of the target split screen application, and the first operating system starts the target split screen application after receiving the touch signal.

[0051] 102. The first operating system accesses an open pluggable specification OPS source through a target split-screen application, and the OPS source is loaded with a second operating system.

[0052] After the target split-screen application is started, it receives the access signal from the OPS source and sends the access signal to the first operating system. The OPS source is the OPS microcomputer described above, which is loaded with the second operating system. At this time, the second operating system is connected to the first operating system through the target split-screen application.

[0053] 103. The first operating system receives a screen splitting instruction from a user.

[0054] The user clicks a split-screen button on the screen to generate a split-screen touch signal, the split-screen touch signal carries a split-screen instruction, and the first operating system receives the split-screen instruction.

[0055] The split-screen button can be a button that floats on the screen and can be dragged at will, or it can be a button fixed at a certain position on the screen. There is no specific limitation here. The shape, size, color, pattern and display method of the split-screen button are not limited here.

[0056] 104. The first operating system divides the screen display interface of the terminal into a first display area corresponding to the first operating system and a second display area corresponding to the second operating system by calling a split screen interface function.

[0057] The first operating system calls the split-screen interface function and inputs the parameters required for the execution of the split-screen interface function into the split-screen interface function, wherein the parameters include: the application ID of the target split-screen application, the split-screen creation method, the activity stack creation method and the initial screen size, wherein the application ID is an ID unique to each application that identifies the application type and is used to determine whether to split the screen. The split-screen creation method is used to determine whether the split-screen is top-down or left-right. The activity stack creation method is used to determine whether to establish a split-screen activity stack or destroy a split-screen activity stack. The initial screen size is the width and height of the entire screen when the screen is not split.

[0058] The split-screen interface function determines whether to start the split-screen based on the application ID. There is a preset list of legal application IDs that meet the split-screen conditions in the split-screen interface function. Only when the input application ID is a legal application ID in the preset list, the split-screen interface function can determine to start the split-screen;

[0059] The first operating system receives the execution result of the split-screen interface function, and after determining to start the split-screen, the split-screen interface function starts drawing the dividing line. The first operating system notifies the target split-screen application that the split-screen is about to be started. After receiving the notification, the target split-screen application adapts the split-screen resources, such as processes, memory, etc., which are not limited to the specifics here. After the target split-screen application recognizes the split-screen state, it configures the automatic UI adaptation of the split-screen layout. The layout includes automatic adaptation of three layouts: horizontal screen, vertical screen and split screen. The specifics are not limited here.

[0060] 105. The first operating system displays a system interface of the first operating system in the first display area, and triggers the second operating system to display a system interface of the second operating system in the second display area.
