Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

The utility model discloses a display, as shown in fig. 1 ~ 5, including USB mouse, USB keyboard, two at least host computers, display, the display is including connecting the USB mouse with USB concentrator module, the connection of USB keyboard the USB of USB concentrator module switches module, display screen, connects the display master control MCU and the video processing module, the connection of display screen the button input module of display master control MCU and video processing module, wherein, display master control MCU and video processing module include display MCU, video processing module, connect display MCU's memory module, USB switches the module respectively through the USB cable with every the host computer is connected, every the host computer respectively with display master control MCU and video processing module's video input interface connection, USB switches the module respectively with display MCU's GPIO1 port, The GPIO2 port connection, the button input module contains the button, the number of button is no less than the number of host computer, the number on the button and the number of host computer one-to-one correspond.

As shown in fig. 1 to 5, the display further includes a display power module and other circuit modules of the display, the power module provides power for the display, 4 hosts can work simultaneously, the server host 1, the server host 2, the server host 3, and the server host 4 are connected to the display through USB cables, and VGA image signals output by the server host 1, the server host 2, the server host 3, and the server host 4 input image data to the display at the same time. The display may display image data of the server host 1, the server host 2, the server host 3, and the server host 4, respectively. The USB mouse and the USB keyboard are arranged on a USB interface of the display, as shown in fig. 1 and fig. 2, the key input module is a key switch, the key switches of '1', '2', '3' and '4' are arranged on the front surface of the display, and a currently selected server host is displayed on a display screen at the upper right corner of the display, so that a user can conveniently switch different server hosts. After the display is started, image signals of the server host 1, the server host 2, the server host 3 and the server host 4 are automatically detected, if no video input signal of the host can be detected, no signal input is displayed, if the server host 1, the server host 2, the server host 3 and the server host 4 work normally, the display can display video pictures of the server according to the priority sequence of 1,2,3 and 4, the key input module comprises keys, the number of the keys is not less than that of the host, and the number numbers on the keys correspond to the number numbers of the host one by one.

For example, the server host 1, the server host 2, the server host 3, and the server host 4 all normally have video output, and the screen of the server host 1 is displayed, and at this time, the screens of the

hosts

2,3, and 4 are not displayed, as shown in fig. 3 and 4, the relationship between the level changes of GPIO1 and GPIO2 is seen according to the logic diagram of the circuit diagram of the USB switching module, for example: the user needs to tap the key "4" on the display if he needs to switch to the screen of the server host 4. When the display MCU receives that the No. 4 key is pressed, the video input of the display is switched to the VGA video signal input of the server host 4, and then the GPIO1 of the MCU outputs high potential and the GPIO2 also outputs high potential. The high potentials of the GPIO1 and the GPIO2 control the pins S0 and S1 of the U2 of the USB switching module to also input the high potential. The USB hub module is thus connected to the USB cable of the server host 4. The mouse and keyboard thus become input devices for the server host 4, thus controlling the server host 4. Meanwhile, the OSD of the display displays the corresponding text of the server host 4 on the display screen. At this time, the display main control MCU module automatically switches the USB switching module to the USB interface of the server host 4, so that the USB of the keyboard and the mouse are connected to the server host 4, and the operation of the server host 4 can be controlled.

Similarly, when the user needs to switch to the server host 2 after completing the operation of the server host 4, the user may touch the key "2" of the display. When the display main control MCU module receives the information of the key 2 of the user, the current display picture is switched to the picture of the server host machine 2, then the switching signal is output to the USB switching module through the GPIO port, and the USB cables of the mouse and the keyboard are connected to the USB port of the host machine 2, so that the operation of the host machine 2 can be controlled. In the same way, the user can freely switch different server hosts to share the display, the mouse and the keyboard.

And each host is respectively connected with the video input interfaces of the display main control MCU and the video processing module through a VGA or VGA-to-DVA module. Through VGA or VGA to DVA modules, server hosts with different interfaces can be connected with a display through DVA or VGA interfaces.

The above detailed description of the embodiments of the present invention has been made in conjunction with the accompanying drawings and the working principle of the present invention has been explained, but the present invention is not limited thereto, and various changes made within the knowledge range possessed by the skilled in the art without departing from the gist of the present invention are all within the protection scope of the present invention.
