[0024] Figure 1 Functional block schematic diagram of the multi-computer switching device of the embodiment of the present application. Figure 2 Flow chart for standby mode judgment of the multi-computer switching device of the embodiment of the present application. Figure 3 Schematic diagram for displaying prompt pattern in picture split mode of the multi-computer switching device of the embodiment of the present application. Referring to Figure 1 As shown in the figure, the present application provides a multi-computer switching device 1, which comprises a processing circuit 10, a switching circuit and a control right prompt circuit 30. The processing circuit 10 is electrically connected with the switching circuit 20 and the control right prompt circuit 30.

[0025] In this embodiment, the processing circuit 10 can be a processor, a microcontroller or a microprocessor. The switching circuit 20 can be a switching component or a relay. The control right prompting circuit 30 can be an application specific integrated circuit or a digital signal processing circuit. The input device IN is an operation interface which can input instructions, for example, one or more of a mouse, a keyboard, a touchpad and a joystick.

[0026] In this embodiment, the processing circuit 10 is electrically connected to the input device IN, and the switching circuit 20 is electrically connected to the processing circuit 10, the input device IN, the first computer host H1, the second computer host H2 and the display device DP. The control right prompting circuit 30 is electrically connected to the processing circuit 10 and the display device DP. In addition, the processing circuit 10 is electrically connected to the input switching interface 40 and the image switching interface 50.

[0027] Further explanation of the steps of signal processing of the multi-computer switching device 1 is as follows. Figure 2 As shown in the figure, step S1: the processing circuit is electrically connected to the input device and receives the input signal of the input device.

[0028] The processing circuit 10 in the multi-computer switching device 1 receives the input switching instruction 140 input by the user through the keyboard or the mouse, or the input switching instruction 140 input through the input switching interface 40 in the multi-computer switching device 1, for example, a timing start input switching instruction 140 can be set in the multi-computer switching device 1. When the processing circuit 10 receives the input switching instruction 140 from the input device IN or the input switching interface 40, the input switching signal 120 is generated according to the input switching instruction 140 and transmitted to the switching circuit 20.

[0029] Further explanation, the processing circuit 10 is connected to the first computer host H1 or the second computer host H2 through the switching circuit 20. The switching circuit 20 is electrically connected to the processing circuit 10, the input device IN, the first computer host H1, the second computer host H2 and the display device DP. The switching circuit 20 receives the first image signal 210 from the first computer host H1, the second image signal 220 from the second computer host H2 and the input signal from the input device IN or the input switching interface 40, in addition, the first image signal 210 and the second image signal 220 are displayed on the first display area D1 and the second display area D2 of the display device DP respectively. As shown in the figure, Figure 1As shown, the switching circuit 20 has a switch component SW1 on its connection path to the first computer host H1, and another switch component SW2 on its connection path to the second computer host H2. The switching circuit 20 electrically connects the input device IN to either the first computer host H1 or the second computer host H2, allowing the user to operate either the first computer host H1 or the second computer host H2 via the input device IN. In other words, different computer hosts can be controlled via the switching circuit 20 on the display device DP. For example, when the user operates the first computer host H1 via the input device IN, the first computer host H1 is the control target with master control.

[0030] In this embodiment, the multi-computer switching device 1 further includes an input switching interface 40, which is electrically connected to the processing circuit 10. The input switching interface 40 transmits an input switching command 140 to the processing circuit 10 via the input device IN. The processing circuit 10 generates an input switching signal 120 based on the input switching command 140. Specifically, the input switching interface 40 includes a storage element for storing instructions for timed screen switching. At a predetermined time, the processing circuit 10 generates the input switching signal 120 based on the input switching command 140 to control the screen of the display device DP to switch to the predetermined display screen of the host computer.

[0031] The multi-computer switching device 1 also has an image switching interface 50, which is electrically connected to the processing circuit 10. The image switching interface 50 transmits an image switching command 150 to the processing circuit 10. The processing circuit 10 generates an image switching signal 121 according to the image switching command 150. The switching circuit 20 determines the display mode of the display device DP to display the first image signal 210 and the second image signal 220 according to the image switching signal 121. The display mode includes multiple modes, such as screen split mode, mother-and-child screen mode, and display on different screens connected to the multi-computer switching device 1.

[0032] Figure 3 This is a schematic diagram of the multi-computer switching device displaying prompt patterns in screen splitting mode, according to an embodiment of the present invention. Figure 4 This is a schematic diagram of a multi-computer switching device displaying prompt patterns in a parent-child screen mode, according to another embodiment of the present invention. Figure 5 This is a schematic diagram of a multi-computer switching device displaying prompt patterns on two display devices, according to another embodiment of the present invention.

[0033] like Figure 3 As shown, in the screen split mode, the first display area D1 and the second display area D2 of the display device DP are arranged side by side on the screen of the display device DP, and have the same display area. Another display mode is as follows: Figure 4As shown, in the sub-picture mode, the display area of the picture (i.e. sub-picture) of the first display region Dl of the display device DP is smaller than the display area of the picture (i.e. main picture) of the second display region D2. Another display mode is shown in Fig. 2B. Figure 5 As shown, the picture of the first display region Dl is displayed on the first screen of the display device DP, and the picture of the second display region D2 is displayed on the second screen of the display device DP.

[0034] Step S2: The time that the processing circuit does not receive the input signal exceeds a predetermined time. When the processing circuit 10 does not receive any input signal from the input device IN, the input switching interface 40 or the image switching interface 50, or when the processing circuit 10 does not receive the first image signal 210 or the second image signal 220 in response to the switching circuit 20, and the time that the processing circuit 10 does not receive the signal continuously exceeds a predetermined time, the multi-computer switching device 1 enters the standby mode.

[0035] Step S3: The multi-computer switching device enters the standby mode and generates a control right indication signal accordingly.

[0036] When the multi-computer switching device 1 enters the standby mode, a control right indication signal 130 is generated accordingly. The control right indication signal 130 is generated by the control right prompting circuit 30. The control right prompting circuit 30 is electrically connected to the processing circuit 10 and the display device DP. The control right indication signal 130 contains the record of the mouse cursor controlled by the multi-computer switching device 1 before entering the standby mode, i.e. the record of the first computer host Hl or the second computer host H2 where the mouse cursor stays before entering the standby mode.

[0037] Step S4: The control right prompting circuit controls the display device to display a prompt pattern in the first display region or the second display region according to the control target indicated by the control right indication signal.

[0038] According to the control target indicated by the control instruction signal 130, the control display device DP displays a prompt pattern DC in the first display area D1 or the second display area D2. That is, the control instruction signal 130 has a record of the first computer host H1 or the second computer host H2 (i.e., the control target) last controlled by the processing circuit 10 before entering standby mode. In standby mode, this allows the user to identify the control target of the multi-computer switching device 1 via the prompt pattern DC before operating the input device IN. In other words, in standby mode, the control prompt circuit 30 displays the prompt pattern DC in the corresponding display area according to the control target of the control instruction signal 130, allowing the user to immediately identify the first computer host H1 or the second computer host H2 with control authority via the prompt pattern DC.

[0039] like Figure 3 As shown, the prompt pattern DC is located to the left of the first display area D1. Figure 4 As shown, the prompt pattern DC is located to the left of the first display area (i.e., sub-screen) D1. Figure 5 As shown, the prompt pattern DC is located to the left of the first display area D1 on the first screen. The prompt pattern DC can be a strip-shaped area appearing on one side of the display area. The area of ​​the prompt pattern DC is smaller than the area of ​​the corresponding first display area D1 or second display area D2, and the strip-shaped area is a non-saturated color block with a transparency of 30% to 70% relative to the display area. The area or transparency of the prompt pattern DC can be adjusted appropriately to allow the user to identify the display area under their control, while also allowing them to see the display status of the desktop in the display area. However, the example given above is only one possible embodiment and is not intended to limit the present invention.

[0040] In addition, in response to receiving an input signal again after entering standby mode, the processing circuit 10 is configured to end the standby mode and stop outputting the control right indication signal 130. When the control right indication signal 130 is not received, the control right indication circuit 30 stops controlling the display device DP to display the indication pattern DC.

[0042] One of the beneficial effects of this utility model is that the multi-computer switching device provided by this utility model can display prompt patterns in the display area with master control in standby mode through the technical solutions of "the processing circuit generates a control authority indication signal for indicating the control target when entering standby mode" and "after entering standby mode, the control authority prompt circuit controls the corresponding display area to display prompt patterns according to the control target indicated by the control authority indication signal".

[0043] Further, the prompt pattern DC is a non-saturated color block, which can allow the user to identify the display area with control and also see the display state of the desktop of the display area.

[0044] The above disclosed content is only the preferred feasible embodiment of the present application, and does not limit the protection scope of the claims of the present application, so any equivalent technical change made by applying the content of the present application specification and drawings is included in the protection scope of the claims of the present application.
