[0027] Below, some of the present invention are explained to facilitate understanding by those skilled in the art.

[0028] The embodiments of the present application are described below in conjunction with the accompanying drawings.

[0029] See also Figure 1 , Figure 1 is an architecture diagram of a display switching system provided in an embodiment of the present application. Figure 1As shown, the display switching system includes a host 10, a first display 20, a second display 30, and a display switching control device 40, wherein the host 10 is respectively connected to the first display 20, the second display 30 and the display switching control device 40; the display switching control device 40 includes a display switching controller 401, a button 402 and a display screen 403, and the display switching controller 401 is connected to the host 10 and the button 402; the display switching controller 401 is used to send a first control signal for switching the display mode of the first display 20 and the second display 30 to the host 10 when it detects that the button 402 is pressed; the display screen 403 is connected to the display switching controller 401, and the display screen 403 is used to display a target display mode screen, and the target display mode screen includes display mode information, status information of the first display and status information of the second display.

[0030] The host 10 may be a laptop computer, a desktop host, a mini host, etc., which is not limited here.

[0031] The host 10 can run the control drive for switching the display screen, and the display modes include main screen single display, secondary screen single display, duplicate display and extended display. The first display 20 is the main screen and the second display 30 is the secondary screen. The main screen single display refers to the first display 20 displaying the picture alone, the secondary screen single display refers to the second display 30 displaying the picture alone, the duplicate display refers to the second display 30 displaying the same picture as the first display 20, and the extended display refers to the second display 30 and the first display 20 displaying pictures in different working areas.

[0032] The display switching control device 40 includes but is not limited to an MCU (Microcontroller Unit).

[0033] Among them, the button 402 is connected to the display switching controller 401 through a pin. When the button 402 is pressed, the level signal of the pin changes from a low level to a high level. After receiving the high-level electrical signal, the display switching controller 401 generates a first control signal and sends the first control signal to the host 10. After receiving the first control signal, the host 10 runs the control drive for switching the display screen to change the display mode of the first display 20 and the second display 30. The display mode corresponds to a preset switching sequence, for example: main screen single display-secondary screen single display-copy display-extended display. If the current display mode is secondary screen single display, the host runs the control drive to change the display mode, which is to switch the secondary screen single display to copy display.

[0034] The host 10 may communicate with the display switching controller 401 to feed back the current display mode information of the first display 20 and the second display 30 to the host 10 .

[0035] See also Figure 2 , Figure 2 is a schematic diagram of a display mode screen provided by an embodiment of the present application. Figure 2 As shown, the target display mode screen includes time, display mode information, status information of the first display and status information of the second display, the status information includes the connection status and display status between the display and the host, the connection status includes normal connection and abnormal connection, the display status includes normal display and no display, the time is 15:29, the display mode information is "the current display mode is main screen single display", the status information of the first display is "main screen status: main display is normally connected and normally displayed", and the status information of the second display is "secondary screen status: secondary display is normally connected and not displayed".

[0036] It can be seen that in this example, the display switching system controls the switching of the display modes of the first display 20 and the second display 30 through the display switching control device. The user only needs to perform key operations on the display switching control device 40 to view the current display mode on the display screen, which is conducive to improving the efficiency of switching the display mode of the display switching system.

[0037] In a possible example, the number of the buttons 402 is four, the display modes include main screen single display, secondary screen single display, copy display and extended display, and each button 402 corresponds to a display mode.

[0038] See also Figure 3 , Figure 3 It is an architecture diagram of another display switching system provided in an embodiment of the present application.

[0039] Among them, the four buttons 402 are a first button 4021, a second button 4022, a third button 4023 and a fourth button 4024, and the first button 4021, the second button 4022, the third button 4023 and the fourth button 4024 are connected to the display switching controller 401 through a first pin, a second pin, a third pin and a fourth pin respectively, and the first button 4021, the second button 4022, the third button 4023 and the fourth button 4024 correspond to the main screen single display, the secondary screen single display, the copy display and the extended display respectively; when the first button 4021 is pressed, the level signal of the first pin changes from a low level to a high level, and the display switching controller 401 generates a third control signal after receiving the high level electrical signal of the first pin, and sends the third control signal to the host 10, and the host 10 runs the control drive for switching the display screen after receiving the third control signal, and switches the current display mode to the main screen single display; when the second button 4022 is pressed, the level signal of the second pin changes from a low level to a high level, and the display switching controller After receiving the high-level electrical signal of the second pin, the controller 401 generates a fourth control signal and sends the fourth control signal to the host 10. After receiving the fourth control signal, the host 10 runs the control drive for switching the display screen to switch the current display mode to the secondary screen single display; when the third button 4023 is pressed, the level signal of the third pin changes from a low level to a high level. After receiving the high-level electrical signal of the third pin, the display switching controller 401 generates a fifth control signal and sends the fifth control signal to the host 10. After receiving the fifth control signal, the host 10 runs the control drive for switching the display screen to switch the current display mode to the copy display; when the fourth button 4024 is pressed, the level signal of the fourth pin changes from a low level to a high level. After receiving the high-level electrical signal of the fourth pin, the display switching controller 401 generates a sixth control signal and sends the sixth control signal to the host 10. After receiving the sixth control signal, the host 10 runs the control drive for switching the display screen to switch the current display mode to the extended display.

[0040] It can be seen that in this example, the display switching system controls the display mode switching through the first button 4021, the second button 4022, the third button 4023 and the fourth button 4024, which is conducive to improving the efficiency of the display mode switching.

[0041] In a possible example, the display switching control device 40 includes an indicator light 404, and the display switching controller 401 is connected to the indicator light 404; the display switching controller 401 is used to light up the indicator light 404, and the indicator light 404 is used to indicate the display modes of the first display 20 and the second display 30.

[0042] The indicator light 404 may correspond to four colors, each color indicating a display mode, for example: blue, white, yellow and green, blue, white, yellow and green respectively correspond to the main screen single display, the secondary screen single display, the copy display and the extended display. If the current display mode is the secondary screen single display, the display switching controller 401 controls the indicator light 404 to be white.

[0043] Optionally, the indicator light 404 also corresponds to red. When the first display or the second display 30 in use is not connected normally, the display switching controller 401 controls the indicator light 404 to be red. For example, when the display mode is the main screen single display, and the first display 20 is not connected normally at this time, the display switching controller 401 controls the indicator light 404 to be red.

[0044] It can be seen that in this example, the display switching system indicates the current display mode of the display by lighting up the indicator light 404 in different colors, which is helpful for the user to identify and improve the user's experience.

[0045] In a possible example, the number of the indicator lights is four, and each indicator light indicates a display mode.

[0046] See also Figure 4 , Figure 4 It is an architecture diagram of another display switching system provided in an embodiment of the present application.

[0047] Among them, the four indicator lights are the first indicator light 4041, the second indicator light 4042, the third indicator light 4043 and the fourth indicator light 4044, and the first indicator light 4041, the second indicator light 4042, the third indicator light 4043 and the fourth indicator light 4044 are respectively connected to the display switching controller 401, and the first indicator light 4041, the second indicator light 4042, the third indicator light 4043 and the fourth indicator light 4044 correspond to the main screen single display, the secondary screen single display, the copy display and the extended display respectively; if the current display mode is the main screen single display, the display switching controller 401 controls the lighting of the first indicator light 4041; if the current display mode is the secondary screen single display, the display switching controller 401 controls the lighting of the second indicator light 4042; if the current display mode is the copy display, the display switching controller 401 controls the lighting of the third indicator light 4043; if the current display mode is the extended display, the display switching controller 401 controls the lighting of the fourth indicator light 4044.

[0048] Optionally, the first indicator light 4041, the second indicator light 4042, the third indicator light 4043 and the fourth indicator light 4044 may correspond to two colors, one color corresponds to the state of the display being used being normally connected, and the other color corresponds to the state of the display being used being not normally connected. For example, the first indicator light 4041, the second indicator light 4042, the third indicator light 4043 and the fourth indicator light 4044 may correspond to two colors, red and white, white corresponds to the state of the display being used being normally connected, and red corresponds to the state of the display being not normally connected. If the current display mode is the main screen single display, and the first display 20 is not normally connected, then the display switching controller 401 controls the first indicator light 4041 to light up in red.

[0049] It can be seen that in this example, the display switching system indicates the current display mode of the display by lighting up the first indicator light 4041, the second indicator light 4042, the third indicator light 4043 and the fourth indicator light 4044, which is beneficial for user identification and improves the user experience.

[0050] In a possible example, the display switching control device 40 includes four silk-screen marks, each of which indicates a display mode, and the four silk-screen marks are respectively arranged on a housing of the display switching control device 40 .

[0051] Among them, the first indicator light 4041, the second indicator light 4042, the third indicator light 4043 and the fourth indicator light 4044 correspond to four different silk-screen marks, and the silk-screen marks are used to indicate the display mode. The four silk-screen marks are silk-screened on the outer casing of the display switching control device 40, and the positions correspond to the top of the first indicator light 4041, the second indicator light 4042, the third indicator light 4043 and the fourth indicator light 4044 respectively.

[0052] The silk-screen logo includes but is not limited to text and patterns, which are not limited here.

[0053] It can be seen that in this example, by silk-screening four different silk-screen logos on the housing of the display switching control device 40, it is convenient for users to identify the display mode, which is beneficial to improving the user experience.

[0054] In a possible example, the host 10 is connected to the first display 20 via a first HDMI interface, and the host 10 is connected to the second display 30 via a second HDMI interface.

[0055] Among them, HDMI (High Definition Multimedia Interface) is a fully digital video and sound transmission interface that can transmit uncompressed audio and video signals.

[0056] The host 10 and the first display 20 and the second display 30 may also be connected via a DisplayPort interface, a VGA (Video Graphics Array) interface, or a DVI (Digital Visual Interface) interface, which is not limited here.

[0057] In a possible example, the host 10 is connected to the display switching controller 401 via a USB interface.

[0058] In a possible example, the display switching system includes a wireless receiving module, which is connected to the display switching controller 401 , and is used to receive the second control signal sent by the wireless transmitting module.

[0059] The wireless transmission module may be a wireless remote controller such as an infrared remote controller.

[0060] Among them, the second control signal is used to indicate the switching of the display mode. After receiving the second control signal, the wireless receiving module sends the second control signal to the display switching controller 401. After receiving the second control signal, the display switching controller 401 sends the second control signal to the host 10. The host 10 runs the driver for switching the display and switches the display mode based on the second control signal. For example: if the second control signal indicates that the current display mode is switched to the secondary screen independent display, the host 10 runs the driver for switching the display to switch the current display mode to the secondary screen independent display.
