In the present embodiment, a display system SYS for dividing a screen by using a KVM switch is provided. The display system SYS for dividing pictures by using the KVM comprises a KVM switch 1 and a plurality of display devices DP1-DPN.
The KVM switch 1 is connected to a signal provider SPD. The display devices DP1-DPN are respectively connected to the KVM switch 1. The plurality of display devices DP1-DPN are arranged in a first arrangement. In this embodiment, the first arrangement shape is a matrix type. The first arrangement shape may be a diamond shape, a circular shape or an irregular shape, which is not limited in the present utility model.
The signal providing device SPD provides a first image information with a first resolution to the KVM switch 1. The first resolution is for example 8K.
The KVM switch 1 cuts the first image information according to the first arrangement shape of the display devices DP1-DPN to generate a plurality of arrangement image information.
That is, the KVM switch 1 can divide the first video information provided by the signal providing device SPD according to the arrangement shape and position of the display devices DP1-DPN to generate a plurality of arrangement video information RIMG1-RIMGN, and transmit the plurality of arrangement video information RIMG1-RIMGN to the display devices DP1-DPN for display. The plurality of display devices DP1-DPN display a plurality of arrangement image information RIMG1-RIMGN, respectively. Therefore, the plurality of arrangement image information RIMG1-RIMGN collectively form the first image information IMG1 in the first arrangement shape.
For example, the first resolution of the first video information is 8K, and the display devices DP1 to DPN are 4×4 matrix arrangement shapes in fig. 1. That is, the resolution of the arrangement picture information RIMG1 to RIMGN provided to each display device DP1 to DPN may be (8K/16) =0.5K.
That is, each of the display devices DP1 to DPN only needs to be responsible for displaying the image content of the resolution of 0.5K, so as to exhibit the image quality of the original first resolution (8K).
Similarly, when the first resolution of the first image information is 16K, the 16 display devices DP1-DPN in fig. 1 can display the image information with the resolution of 1K, i.e. can display the 16K image quality of the first image information.
In the present embodiment, the plurality of display devices DP1 to DPN may be display devices having the same resolution, for example, a plurality of display devices also having common resolutions of 1920×1080 (1080P), 1024×768, 1024×800, and the like. That is, first, these display devices DP1 to DPN having the same resolution may be the same model, the same size display devices manufactured by the same manufacturer.
Referring to fig. 3, the KVM switch 1 includes a control circuit 10, a memory circuit 11, an image information processing circuit 12, a first port circuit 13, a second port circuit 14 and a screen display circuit 15. The KVM switch 1 is further connected to a keyboard 2, a mouse 3 and signal providing devices SPD. The control circuit 10 is connected to the memory circuit 11, the image information processing circuit 12, the first port circuit 13, the second port circuit 14, and the screen display circuit 15. The screen display circuit 15 is also connected to the video information processing circuit 12.
In the present embodiment, the number of the signal providing devices SPDs is 1, and the signal providing devices SPDs are connected to the first port circuit 13. However, the number of the signal providing devices SPD may be adjusted according to actual requirements, which is not limited in the present utility model. That is, the first port circuit 13 may include a plurality of first port units 131, and is connected to a plurality of signal providing devices SPD.
Similarly, the second port circuit 14 also includes a plurality of second port units 141. The plurality of second port units 141 are respectively connected to the plurality of display devices DP1 to DPN.
The arrangement positions where the plurality of display devices DP1 to DPN are arranged according to the first arrangement shape are stored in the storage circuit 11. Similarly, individual resolution settings of the plurality of display devices DP1 to DPN are also stored in the memory circuit 11. The control circuit 10 may provide control signals to the image information processing circuit 12 according to the corresponding arrangement positions and resolution settings of the plurality of display devices DP1-DPN in the storage circuit 11 to divide the first image information IMG provided by the signal providing device SPD to generate a plurality of arrangement image information RIMG1-RIMGN. Then, the control circuit 10 controls the image information processing circuit 12 to provide a plurality of arrangement image information RIMG1-RIMGN to the plurality of display devices DP1-DPN.
Further, the second port circuit 14 may be a wired connection circuit or a wireless connection circuit. That is, the plurality of display devices DP1-DPN may be connected to the KVM switch 1 by wire or connected to the KVM switch 1 by wireless.
Further, the resolution setting of each display device DP1-DPN may be selected in advance according to the respective highest resolution or a built-in resolution list in each display device DP1-DPN to decide. After the plurality of display devices DP1-DPN are connected, the control circuit 10 of the KVM switch 1 can obtain the resolution setting of the plurality of display devices DP1-DPN in advance to determine whether the plurality of display devices DP1-DPN display the first image information IMG1 at the same resolution or with different resolutions.
In addition, the on-screen display circuit (On Screen Display, OSD) 15 sends a communication signal to the control circuit 10. The control circuit 10 detects the area where the coordinates of a pointer displayed on any one of the display devices DP1 to DPN are located, and issues a confirmation signal to the screen display circuit 15. The screen display circuit 15 adjusts the screen display of the area where the coordinates of the pointer are located based on the obtained confirmation signal.
As shown in fig. 1, the display devices DP1-DPN are arranged in a matrix arrangement to form a display wall.
Fig. 4A is a display wall composed of 3×3 display devices. Fig. 4B includes 2×2 display devices. In other embodiments, the number of the display devices DP1-DPN may be adjusted according to actual requirements, which is not limited in the present utility model.
In addition, the KVM switch 1 can cut the first image information IMG1 according to the arrangement shape of the display devices DP1-DPN and the size of the display devices DP1-DPN, and transmit the corresponding arrangement image information RIMG1-RIMGN to the display devices DP1-DPN for displaying. In addition, the image cutting mode is processed according to the size and arrangement shape of each display device DP1-DPN. The image information processing circuit 12 calculates the sum of the sizes (pixels) of each of the display devices DP1-DPN and the arrangement shape of the plurality of display devices DP1-DPN, compares the number of pixels of the first image information IMG1, and cuts the display devices according to the ratio of the size (pixels) of each of the display devices DP1-DPN to the sum of the sizes (pixels) of the plurality of display devices DP1-DPN.
If the shapes are arranged in a matrix, it is possible to precisely display on each of the display devices DP1 to DPN according to the size (pixel) of each of the display devices DP1 to DPN. If other arrangement shapes, such as diamond or irregular shapes, the image information processing circuit 12 of the KVM switch 1 cuts the first image information IMG1 to conform to the arrangement shapes of the display devices DP1-DPN.
In this embodiment, the first resolution is a resolution of 4K or 8K. In other embodiments, the first resolution may also be a 12K or 16K resolution.
The signal providing device SPD is a desktop computer, a notebook computer, a tablet computer, a smart phone, an image playing device or a server.
