[0027] Figure 1 Is a schematic block diagram of an example computing device 100.

[0028] As Figure 1 Shown, in the basic configuration 102, the computing device 100 typically includes a system memory 106 and one or more processors 104. A memory bus 108 can be used for communication between the processor 104 and the system memory 106.

[0029] Depending on the desired configuration, the processor 104 can be any type of processing, including but not limited to: microprocessor (UP), microcontroller (UC), digital signal processor (DSP), or any combination thereof. The processor 104 can include one or more levels of cache such as a level - one cache 110 and a level - two cache 112, a processor core 114, and registers 116. An example processor core 114 can include an arithmetic logic unit (ALU), a floating - point unit (FPU), a digital signal processing core (DSP core), or any combination thereof. An example memory controller 118 can be used with the processor 104, or in some implementations, the memory controller 118 can be an internal part of the processor 104.

[0030] Depending on the desired configuration, system memory 106 can be any type of memory, including but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. System memory 106 can include an operating system 120, one or more applications 122, and program data 124. In some embodiments, applications 122 can be arranged to execute instructions on the operating system by one or more processors 104 using program data 124.

[0031] Computing device 100 further includes storage device 132, and storage device 132 includes removable storage 136 and non-removable storage 138.

[0032] Computing device 100 may also include a storage interface bus 134. The storage interface bus 134 enables communication from the storage device 132 (e.g., removable storage 136 and non-removable storage 138) via the bus / interface controller 130 to the basic configuration 102. At least a portion of the operating system 120, applications 122, and data 124 may be stored on the removable storage 136 and / or non-removable storage 138, and when the computing device 100 is powered on or an application 122 is to be executed, it is loaded into the system memory 106 via the storage interface bus 134 and executed by one or more processors 104.

[0033] Computing device 100 may also include an interface bus 140 that facilitates communication from various interface devices (e.g., output device 142, peripheral interface 144, and communication device 146) to the basic configuration 102 via the bus / interface controller 130.

[0036] In an embodiment according to the present invention, the operating system 120 of the computing device 100 is configured to execute the system desktop split-screen display method 200 according to the present invention. Among them, the operating system 120 of the computing device 100 contains multiple program instructions for executing the system desktop split-screen display method 200 according to the present invention, and these program instructions can instruct the processor to execute the system desktop split-screen display method 200 according to the present invention, so that the computing device 100 can control the system desktop split-screen display based on the user's mouse operation by executing the system desktop split-screen display method 200 according to the present invention.

[0037] According to an embodiment of the present invention, a split-screen display control device 500 is deployed on the operating system 120, and the split-screen display control device 500 contains multiple program instructions for executing the system desktop split-screen display method 200 according to the present invention, so that the system desktop split-screen display method 200 according to the present invention can be executed in the split-screen display control device 500.

[0038] Figure 2The flowchart of the system desktop split-screen display method 200 according to an embodiment of the present invention is shown. The system desktop split-screen display method 200 can be executed in the operating system of a computing device (such as the aforementioned computing device 100). One or more application icons can be displayed on the system desktop, for example, so that the user can start an application by operating the corresponding icon, and the window of the application is displayed on the system desktop.

[0039] It should be noted that the system desktop split-screen display method 200 according to the present invention can be executed in various operating systems, and the present invention is not limited to the specific type of the operating system.

[0040] As Figure 2 shown, the method 200 starts from step S210.

[0041] In step S210, a mouse dragging operation on the system desktop is detected. Here, the mouse dragging operation can be implemented as: an operation of pressing and holding the left mouse button and dragging on the system desktop, and then releasing the mouse after a rectangular dragging coverage area is formed.

[0042] Subsequently, in step S220, the dragging coverage area is determined according to the mouse dragging operation, and it is judged whether the range of the dragging coverage area contains a predetermined area on the system desktop. Here, the predetermined area is set in advance, and the present invention does not limit the specific position, shape, and size of the predetermined area on the system desktop.

[0043] In step S230, if it is determined that the range of the dragging coverage area contains the entire predetermined area, the system desktop is controlled to perform split-screen display. On the contrary, if the range of the dragging coverage area does not contain the entire predetermined area, the system desktop is not split-screen displayed.

[0044] It should be noted that controlling the system desktop to perform split-screen display means that at least two display areas are divided and formed on the screen of the computing device 100, and a system desktop is respectively displayed in each display area, so as to realize the display of multiple system desktops on one screen.

[0045] According to an embodiment of the present invention, the predetermined area includes a first predetermined area 310 and a second predetermined area 320. When judging whether the dragging coverage area contains the predetermined area, it is judged whether the dragging coverage area contains the first predetermined area 310 or the second predetermined area 320. If it is determined that the dragging coverage area contains the first predetermined area 310, the system desktop is controlled to perform left-right split-screen display, that is, left and right two display areas are divided and formed on the screen of the computing device 100, and a system desktop is respectively displayed in the left and right two display areas, realizing the effect of left-right split-screen display of the system desktop.

[0046] If it is determined that the dragged covering area includes the second predetermined area 320, the control system desktop performs split-screen display in the vertical direction. That is, two display areas are formed by dividing the screen of the computing device 100 in the vertical direction, and a system desktop is respectively displayed in the two upper and lower display areas, achieving the effect of split-screen display of the system desktop in the vertical direction.

[0047] Figure 3 FIG. shows a schematic diagram of triggering split-screen display of the system desktop 300 in the left-right direction according to an embodiment of the present invention. Figure 4 FIG. shows a schematic diagram of triggering split-screen display of the system desktop 300 in the up-down direction according to an embodiment of the present invention.

[0048] As Figure 3 and Figure 4 shown, the system desktop includes a vertical axis (Y-axis) and a horizontal axis (X-axis) that pass through the center of the system desktop 300 and are perpendicular to each other. Here, the vertical axis is in the vertical direction, and the horizontal axis is in the horizontal direction.

[0049] In one embodiment, as Figure 3 shown, the first predetermined area 310 is a long rectangular area arranged along the vertical axis (Y-axis). As Figure 4 shown, the second predetermined area 320 is a long rectangular area arranged along the horizontal axis (X-axis). Here, the present invention does not specifically limit the length and width of the first predetermined area 310 and the second predetermined area 320, and they can be set by those skilled in the art according to actual situations.

[0050] In one embodiment, if the dragged covering area includes the first predetermined area, the control system desktop can be controlled to perform split-screen display in the left-right direction along the vertical axis. That is, two left and right display areas of the same size are formed by dividing the screen along the vertical axis, and a system desktop is respectively displayed in the two left and right display areas.

[0051] If the dragged covering area includes the second predetermined area, the control system desktop can be controlled to perform split-screen display in the up-down direction along the horizontal axis. That is, two upper and lower display areas of the same size are formed by dividing the screen along the horizontal axis, and a system desktop is respectively displayed in the two upper and lower display areas.

[0052] In addition, if the dragged covering area includes both the first predetermined area and the second predetermined area, four display areas of the same size can be formed by dividing the screen along the vertical axis and the horizontal axis, and a system desktop is respectively displayed in the four display areas.

[0053] It should be noted that the operating system includes a desktop application layer arranged at the topmost layer, a display server arranged below the desktop application layer, and a kernel driver layer arranged below the display server. Among them, the split-screen display control device 500 is arranged in the desktop application layer, and the kernel driver layer includes a kernel driver. The display server is, for example, the xorg server.

[0054] According to one implementation, when it is determined that the range of the dragged coverage area includes the entire predetermined area, the system desktop can be controlled to perform split-screen display in the following manner:

[0055] The split-screen display control device 500 in the desktop application layer arranged on the operating system can send the split-screen display instruction to the display driver in the kernel driver layer through an interface. After receiving the split-screen display instruction, the display driver simulates the split-screen operation according to the split-screen display instruction and adjusts the display parameters to be sent to the display server to generate new display parameters. Then, the display driver sends the new display parameters to the display server.

[0056] The display server can adjust the screen display parameters of the computing device according to the new display parameters to trigger the split-screen display logic. Specifically, the display server can divide the screen into at least two display areas according to the new display parameters and display a system desktop in each display area respectively. In this way, the system desktop is controlled to perform split-screen display.

[0057] In addition, in one embodiment, after the system desktop is controlled to perform split-screen display, an option to exit split-screen display can be added to the menu page (right-click menu page) of the system desktop. In this way, the user can call out the menu page by right-clicking the mouse and control the system desktop to exit split-screen display by left-clicking the option to exit split-screen display in the menu page.

[0058] Specifically, when a right-click operation on the system desktop is received, the menu page is displayed on the system desktop. When a click operation on the option to exit split-screen display in the menu page by the user is received, in response to the click operation on the option to exit split-screen display, the system desktop is controlled to exit split-screen display.

[0059] In one implementation, the system desktop can be controlled to exit split-screen display in the following manner:

[0060] The split-screen display control device 500 can send the instruction to exit split-screen display to the display driver in the kernel driver layer. After receiving the instruction to exit split-screen display, the display driver simulates the operation to exit split-screen display according to the instruction to exit split-screen display and sends the process of the operation to exit split-screen display to the display server.

[0061] The display server restores the initial screen display parameters of the computing device according to the received exit split-screen operation, thereby implementing the control system desktop to exit split-screen display and restoring the state of the initial system desktop full-screen display.

[0062] Figure 5 FIG. 4 shows a schematic diagram of a split-screen display control device 500 according to an embodiment of the present invention.

[0063] Figure 3 FIG. 4 shows a schematic diagram of a split-screen display control device 500 according to an embodiment of the present invention. The split-screen display control device 500 is arranged on the operating system of a computing device (such as the aforementioned computing device 100) and is adapted to execute the system desktop split-screen display method 200 of the present invention.

[0064] The split-screen display control device 500 includes a detection unit 510, a determination unit 520, and a control unit 530 that are connected in sequence. Among them, the detection unit 510 detects a mouse dragging operation on the system desktop. The determination unit 520 determines a dragged coverage area according to the mouse dragging operation and determines whether the dragged coverage area includes a predetermined area. When the dragged coverage area includes the predetermined area, the control unit 530 controls the system desktop to perform split-screen display.

[0065] It should be noted that the detection unit 510 is used to execute the aforementioned step S210, the determination unit 520 is used to execute the aforementioned step S220, and the control unit 530 is used to execute the aforementioned step S230. Here, for the specific execution logics of the detection unit 510, the determination unit 520, and the control unit 530, refer to the descriptions of steps S210 to S230 in the foregoing method 200, and details are not described herein again.

[0066] According to the system desktop split-screen display method 200 of the present invention, the system desktop split-screen display can be realized only through a mouse dragging operation. Among them, when the dragged coverage area formed based on the mouse dragging operation includes a predetermined area on the system desktop, the system desktop is controlled to perform split-screen display. In this way, the split-screen display function can be realized quickly and conveniently, improving the operation efficiency. Moreover, the split-screen display solution of the present invention can be used in various operating systems.

[0067] Furthermore, by respectively setting a first predetermined area and a second predetermined area along the vertical axis and the horizontal axis, the system desktop can be controlled to perform left-right split-screen display by controlling the dragged coverage area formed by the mouse operation to cover the first predetermined area, and the system desktop can be controlled to perform up-down split-screen display by controlling the dragged coverage area formed by the mouse operation to cover the second predetermined area.
