This allows the multi-computer switching device 100 to allocate and connect the S input / output ports PT1~PTS to the M display devices DP1,1~DPP,Q according to actual wiring requirements. 1,1 ~DP P,Q The system includes N computer hosts CH1~CHN, the setting computer SC, and the imaging display device ID, thereby increasing the convenience of online configuration.

[0035] It should be noted that S, M, and N are positive integers not less than 0. Furthermore, the number of S input / output ports PT1~PTS is greater than the number of M display devices DP. 1,1 ~DP P,Q The number of S input / output ports PT1~PTS plus the number of N computer hosts CH1~CHN, the number of the setting computer SC, and the number of the imaging display devices ID, are used to ensure that S input / output ports PT1~PTS can simultaneously connect to M display devices DP. 1,1 ~DP P,Q The system includes N computer hosts CH1~CHN, the setting computer SC, and the imaging display device ID.

[0037] In detail, the setting computer SC has multiple built-in signal configuration modes. Engineers can select one of these signal configuration modes through the setting computer SC to configure M display devices DP. 1,1 ~DP P,Q The image display mode is configured so that the setting computer SC outputs the input command.

[0040] It should be noted that, for ease of understanding of this embodiment, the following will describe in detail how the signal distribution circuit 1, in conjunction with the adjustment circuit 11, provides the image signals of N computer hosts CH1~CHN to M display devices DP according to the signal configuration mode. 1,1 ~DP P,Q Displays various states of images.

[0041] [Example 2]

[0042] Please see Figures 2 to 4 As shown, this is Embodiment Two of the present invention. Since this embodiment is similar to Embodiment One described above, the similarities between the two embodiments will not be repeated. The differences between this embodiment and Embodiment One are roughly explained as follows:

[0043] like Figures 2 to 4 As shown, when M of the aforementioned display devices DP 1,1 ~DP P,Q When the number is the same as the number of N computer hosts CH1~CHN, the signal distribution circuit 1 can control M display devices DP according to the signal configuration mode. 1,1 ~DP P,Q The image signals of N computer hosts CH1~CHN are displayed respectively.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, M of the aforementioned display devices DP 1,1 ~DP P,Q The screen wall (DW) comprises a first display device DP1, a second display device DP2, a third display device DP3, and a fourth display device DP4 arranged in a matrix. N computer hosts CH1~CHN, including a first computer host CH1, a second computer host CH2, a third computer host CH3, and a fourth computer host CH4, provide the image signals.

[0045] The S input / output ports PT1~PTS include a first input / output port PT1, a second input / output port PT2, a third input / output port PT3, a fourth input / output port PT4, a fifth input / output port PT5, a sixth input / output port PT6, a seventh input / output port PT7, an eighth input / output port PT8, a ninth input / output port PT9, and a tenth input / output port PT10. The first input / output port PT1 is electrically coupled to the setting computer SC. The second input / output ports PT2 to the fifth input / output port PT5 are electrically coupled to the first computer host CH1 to the fourth computer host CH4. The sixth input / output port PT6 to the ninth input / output port PT9 are electrically coupled to the first display device DP1 to the fourth display device DP4. The tenth input / output port PT10 is electrically coupled to the imaging display device ID.

[0046] As described above, when the image signals corresponding to the first computer host CH1 to the second computer host CH2 are sequentially numbers 1 to 4, the processing circuit 3 can drive the signal distribution circuit 1 to control the first display device DP1 to the fourth display device to sequentially display images of numbers 1 to 4 according to the signal configuration mode.

[0047] It should be noted that when M of the aforementioned display devices DP 1,1 ~DP P,Q When it is necessary to display the image signals of multiple computer hosts CH1~CHN (N computer hosts CH1~CHN), the adjustment circuit 11 receives the multiple image signals through S input / output ports PT1~PTS and adjusts the resolution of the multiple image signals so that the resolution of M display devices DP... 1,1 ~DP P,Q Displaying multiple image signals of the same resolution enhances the overall viewing experience.

[0048] In this embodiment, the adjustment circuit 11 receives the image signals of numbers 1 to 4 from the first computer host CH1 to the fourth computer host CH4, and the adjustment circuit 11 first adjusts the resolution of the image signals of numbers 1 to 4, and then drives the first display device DP1 to the fourth display device DP4 to display the images of numbers 1 to 4, so that the images of numbers 1 to 4 displayed by the screen wall DW have the same resolution, thereby improving the overall viewing experience.

[0049] like Figure 2 and Figure 4 As shown, the signal distribution circuit 1 can control M display devices DP according to the signal configuration mode. 1,1 ~DPP,Q At least two adjacent display devices DP1 and DP3 display the image signal of a computer host CH2.

[0050] It should be noted that the adjustment circuit 11 can divide the image signal of one computer host CH2 into multiple sub-image signals according to the signal configuration mode, and the adjustment circuit 11 transmits the multiple sub-image signals to M display devices DP. 1,1 ~DP P,Q At least two adjacent display devices DP1, DP3 are used to image the image signal of a computer host CH2.

[0051] In this embodiment, the signal distribution circuit 1 controls the adjacent first display device DP1 and third display device DP3 to display the image signal of the number 2 of the second computer host CH2 according to the signal configuration mode. The adjustment circuit 11, according to the signal configuration mode, segments the image signal of the number 2 of the second computer host CH2 into a first sub-image signal (i.e., the upper half of the image of number 2) and a second sub-image signal (i.e., the lower half of the image of number 2), and the adjustment circuit 11 transmits the first sub-image signal and the second sub-image signal to the first display device DP1 and the third display device DP3 respectively, to display the image signal of the number 2 of the second computer host CH2.

[0052] like Figure 2 and Figure 5 As shown, it should be noted that in some applications of the DW (Display Wall), due to the screen bezel design, the bottommost display devices (i.e., the third display device DP3 and the fourth display device DP4) need to be placed in reverse. Therefore, the images displayed by the bottommost display devices need to be reversed to avoid displaying incorrect images on the screen. Specifically, the adjustment circuit 11 can reverse a portion of the sub-image signals according to the signal configuration mode, and transmit the unreversed sub-image signals and the reversed sub-image signals to two or more adjacent display devices among the M display devices DP1,1~DPP,Q (i.e., the first display device DP1 to the fourth display device DP4) to image the image signal of a computer host CH1~CH4.

[0053] In this embodiment, the first display device DP1 to the fourth display device DP4 display the O-shaped image signal of the first computer host CH1. When the third display device DP3 and the fourth display device DP4 are placed opposite each other, the adjustment circuit 11 reverses the sub-image signals to be displayed by the third display device DP3 and the fourth display device DP4 according to the signal configuration mode, and then transmits the sub-image signals to the third display device DP3 and the fourth display device DP4.

[0054] It should be noted that the adjustment circuit 11 can adjust the resolution of multiple sub-image signals to the same size, so that the M display devices DP 1,1 ~DP P,Q Two or more adjacent display devices DP1 to DP4 image the image signal of a computer host CH1. In this embodiment, the adjustment circuit 11 can adjust the resolution of the sub-image signals displayed by the first display device DP1 to the fourth display device DP4 to the same size to improve the overall viewing experience.

[0055] [Example 3]

[0056] Please see Figure 6 As shown, this is Embodiment 3 of the present invention. Since this embodiment is similar to the above embodiments, the similarities between this embodiment and the above embodiments will not be repeated. The differences between this embodiment and the above embodiments are roughly explained as follows:

[0057] like Figure 6 As shown, in this embodiment, the multi-computer switching device 100 further includes a control transmission box CTX, four signal transmission boxes TX1~TX4, an imaging receiver box DRX, and four signal receiver boxes RX1~RX4. The control transmission box CTX is electrically coupled between the setting computer SC and the input / output ports PT1~PT10. The control transmission box CTX has an amplification function to amplify the signal strength of the input command.

[0058] It should be noted that the setting computer SC can increase the signal strength of the input command through the control transmission box CTX, thereby increasing the transmission distance of the input command and increasing the distance between the setting computer SC and the signal distribution circuit 1 to facilitate the setting of the multi-computer switching device 100.

[0059] The four signal transmission boxes TX1~TX4 are electrically coupled between the four computer hosts CH1~CH4 and the input / output ports PT1~PT10, respectively. Each of the four signal transmission boxes TX1~TX4 has an amplification function to amplify the image signal output by the four signal transmission boxes TX1~TX4, thereby increasing the transmission distance of the image signal and thus increasing the distance between the computer hosts CH1~CH4 and the signal distribution circuit 1, thus facilitating the configuration of the multi-computer switching device 100.

[0060] It should be noted that the number of signal transmission boxes TX1~TX4 corresponds to the number of computer hosts CH1~CH4. Therefore, when the number of computer hosts CH1~CH4 is N, the number of signal transmission boxes TX1~TX4 also corresponds to N.

[0061] The imaging receiver box DRX is electrically coupled between the imaging display device ID and the input / output ports PT1~PT10 to drive the imaging display device ID to display the image according to the signal configuration mode. It should be noted that the imaging receiver box DRX receives the image allocation display signal and sends the image allocation display signal to the imaging display device ID. Thus, the imaging receiver box DRX acts as a signal receiving buffer for the imaging display device ID.

[0062] The four signal receiving boxes RX1~RX4 are electrically coupled between the four display devices DP1~DP4 and the input / output ports PT1~PT10, respectively, to drive the four display devices DP1~DP4 to display images according to the signal configuration mode. It should be noted that the four signal receiving boxes DP1~DP4 function similarly to the imaging receiving box DRX, serving as a signal receiving buffer for the four display devices DP1~DP4.

[0063] It should be noted that the number of signal receiving boxes RX1~RX4 corresponds to the number of display devices DP1~DP4. Therefore, when the number of display devices DP1~DP4 is M, the number of signal receiving boxes RX1~RX4 also corresponds to M.

[0064] [Example 4]

[0065] Please see Figure 7 As shown, this is Embodiment 4 of the present invention. Since this embodiment is similar to the embodiments described above, the similarities between this embodiment and the embodiments described above will not be repeated. The differences between this embodiment and the embodiments described above are roughly explained as follows:

[0066] like Figure 7As shown, in this embodiment, there are M display devices DP 1,1 ~DP P,Q (like Figure 1 As shown, three screen walls can be arranged, namely a first screen wall DW1, a second screen wall DW2, and a third screen wall DW3. The first screen wall DW1 is a 2x2 screen wall composed of four display devices DP1-DP4 arranged in a matrix. The second screen wall DW2 uses a large-sized display device DP5. The third screen wall DW3 is a 2x3 screen wall composed of six display devices DP6-DP11 arranged in a matrix, but this invention is not limited to this. For example, M display devices DP6-DP11... 1,1 ~DP P,Q The number of screen walls that can be arranged can be adjusted according to the actual design requirements.

[0067] The signal distribution circuit 1 can distribute the image signals of the computer hosts CH1~CH11 to the first screen wall DW1 to the third screen wall DW3 according to the signal configuration mode to display the image signals of the computer hosts CH1~CH11.
