Referring to fig. 1, fig. 2A and fig. 2B, fig. 1 is a schematic diagram of a kvm switch capable of displaying a main control screen according to an embodiment of the utility model, fig. 2A is a schematic diagram of the kvm switch capable of displaying a display screen in a first display area of a display device according to an embodiment of the utility model, and fig. 2B is a schematic diagram of the kvm switch capable of displaying a main control screen according to an embodiment of the utility model displaying a display screen in a second display area of the display device. The KVM switch 1 capable of indicating a main control screen (hereinafter referred to as KVM switch for convenience of description) includes, but is not limited to, a processing circuit 10, a switching circuit 12, a host port 14, a screen allocation circuit 16, an on-screen display (On Screen Display, OSD) circuit 18, and an operation interface 11. The processing circuit 10 is electrically connected to the switching circuit 12, the operation interface 11, the frame distribution circuit 16 and the screen display circuit 18, respectively. The host port 14 includes, for example, a first port 141 and a second port 142, and the first port 141 and the second port 142 can be respectively connected to the first computer host C1 and the second computer host C2.
The switching circuit 12 determines whether the first host computer C1 or the second host computer C2 can receive the input signal of the input device ID according to the input operation of the user on the operation interface 11. The switching circuit 12 is electrically connected to the first computer host C1 or the second computer host C2 according to the controlled input device ID after operation. The input device 40 is, for example, a mouse or a keyboard, but the utility model is not limited thereto.
For example, when the switching circuit 12 switches selection to the first computer host C1 to receive the input signal, the processing circuit 10 receives the input signal of the input device ID and outputs the input signal to the first computer host C1 through the switching circuit 12 and the first port 141. At this time, the processing circuit 10 may be electrically connected to the first computer host C1 through the first port 141, and receive a first image signal sent by the first computer host C1, and output the first image signal to the display device D for display.
When the switching circuit 103 switches to select to the second host computer C2 to receive the input signal, the processing circuit 10 receives the input signal of the input device ID and outputs the input signal to the second host computer C2 through the switching circuit 12 and the second port 142. At this time, the processing circuit 10 may be electrically connected to the second computer host C2 through the second port 142, and receive a second image signal sent by the second computer host C2, and output the second image signal to the display device D for display.
The first port 141 and the second port 142 are illustrated here by way of example, but the utility model is not limited thereto, and the number of ports may be correspondingly set according to the number of connected computers.

For example, the processing circuit 10 generates corresponding image distribution signals with respect to the control frame distribution circuit 16 according to the first image signal of the first host computer C1 and the second image signal of the second host computer C2, so that the display device D divides its display area into a first display area DP1 and a second display area DP2 according to the image distribution signals.
In one embodiment, the frame distribution circuit 16 may receive the first video signal from the first port 141 and the second video signal from the second port 142 according to the control of the processing circuit 10. And the screen distributing circuit 16 can output the first image signal to the first display area DP1 of the display device D for display and output the second image signal to the second display area DP2 of the display device D for display according to the image distributing signal.
It should be noted that, the processing circuit 10 outputs a display screen BP to the first display area DP1 or the second display area DP2 of the display device D according to the switching result of the switching circuit 12 relative to the control screen display circuit 18. For example, when the switching circuit 12 switches the selection input device ID to be electrically connected to the first host computer C1, the processing circuit 10 controls the indication screen BP output by the screen display circuit 18 to be displayed in the first display area DP1, and as shown in fig. 2A, the first display area DP1 displays the indication screen BP in addition to the manipulated cursor. When the switching circuit 12 switches the selection input device ID to be electrically connected to the second host computer C2, the processing circuit 10 controls the display screen BP output by the screen display circuit 18 to be displayed in the second display area DP2, and as shown in fig. 2B, the second display area DP1 displays the cursor for manipulation and the display screen BP.
Further, the display area of the indication frame BP is smaller than the display area of the first display area DP1 and the display area of the second display area DP2, and the indication frame BP may be displayed on any side of the first display area DP1 or the second display area DP2. Furthermore, the display aspect of the indication frame BP is, for example, a transparent display block or a reflective display block, and the display shape of the indication frame BP is, for example, a quadrangle, a triangle, a circle or a star. The display position, area, pattern or shape of the indication frame BP is merely illustrative, and is not intended to limit the present utility model.
Accordingly, when the first computer host C1 and the second computer host C2 are respectively connected to the KVM switch 1 for use, the display device D is at least automatically divided into the first display area DP1 and the second display area DP2 by the frame distribution circuit 16, and the KVM switch 1 can output and display the first video signal of the first computer host C1 in the first display area DP1 and the second video signal of the second computer host C2 in the second display area DP2.
Therefore, when the user performs the operation on the first computer host C1 through the KVM switch 1, the first computer host C1 can receive the input signal of the input device ID through the switching selection of the switching circuit 12, and the cursor in the input signal is also displayed in the first display area DP1 of the display device D as shown in FIG. 2A. The indication frame BP is displayed in the first display area DP1, so that the user can intuitively and easily see the indication frame BP and know that the current input device ID is being controlled by the first host computer C1.
On the other hand, when the user performs the operation on the second computer host C2 through the KVM switch 1, the second computer host C2 can receive the input signal of the input device ID through the switching selection of the switching circuit 12, and the cursor in the input signal is also displayed in the second display area DP2 of the display device D as shown in FIG. 2B. And the indication picture BP is displayed in the second display area DP2 at the same time, so that the user can intuitively and easily see the indication picture BP, and then know that the current input device ID is operated on the second computer host C2.
It should be noted that the host computer connected to the KVM switch 1 is illustrated as 2 host computers, but the utility model is not limited thereto. For example, when the number of computers connected to the KVM switch 1 is 3, the display device D can be automatically divided into 3 display areas by the frame distribution circuit 16, and the image signals of the corresponding computers can be displayed individually. When the number of the computers connected to the KVM switch 1 is 4, the display device D can be automatically divided into 4 display areas by the frame distribution circuit, and the image signals of the corresponding computers can be displayed individually. That is, the number of computers connected to the KVM switch 1 and how many display areas the display device D can be automatically divided into by the frame distribution circuit 16 are based on the above principle, and the description thereof is omitted herein. And the sizes of the plurality of divided display areas in the display device D may be the same or different, the plurality of divided display areas in the display device D may be displayed in an overlapping or non-overlapping arrangement, and the sum of the display sizes of the plurality of display areas may be greater than, equal to, or less than the display size of the display device D.
On the other hand, the KVM switch 1 is only displayed in the display screen of the currently operated host computer via the indication screen BP, so that a striking effect can be achieved in a plurality of display areas of the display device D, and when different host computers are switched, the indication screen BP is correspondingly switched to the display screen of the latest operated host computer synchronously, so that a user can quickly know which of the plurality of host computer screens belongs to the main control screen being operated.
