Detailed Implementation

[0041] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] With the continuous development of display technology, a single monitor can be connected to multiple terminal devices via a switcher. However, when users need to switch the display screen of different terminal devices on the monitor, they need to manually click the switch button each time, which is inconvenient. Especially when users need to frequently switch the display screen of terminal devices, they need to click the switch button frequently, which not only makes the screen switching speed slow but also affects the user's normal work, resulting in a poor user experience.

[0044] To address this, this application provides a display. A terminal switching module acquires the terminal operation signal from the input device and converts it into an interface switching signal. A control module switches the reception of audio and video data from the corresponding terminal device based on the interface switching signal and displays it through a display module. Therefore, when a user switches between the display screens of multiple terminal devices connected to the display, there is no need to click a separate switching button; the user can directly operate the input device, making operation convenient and providing a superior user experience. Simultaneously, the control module can also generate an input device switching signal based on the interface switching signal. The terminal switching module connects the input device and the corresponding terminal device based on the input device switching signal, thereby switching the corresponding control relationship between the input device and the terminal device, facilitating user control of the switched terminal device through the input device.

[0045] The display provided in this application will now be described exemplarily with reference to the accompanying drawings.

[0046] Figure 1 This is a schematic diagram of a first structure of a display provided in an embodiment of this application, as shown below. Figure 1 As shown, exemplarily, a display 100 includes a terminal switching module 1, a control module 2, and a display module 3, wherein the control module 2 is electrically connected to the terminal switching module 1 and the display module 3 respectively.

[0047] The terminal switching module 1 is configured to be electrically connected to the input device 4 and multiple terminal devices 5 respectively, to acquire the terminal operation signal of the input device 4 and convert it into the corresponding interface switching signal, and to connect the input device 1 and the corresponding terminal device 5 according to the input device switching signal.

[0048] The control module 2 is configured to be electrically connected to multiple terminal devices 5, and to switch to receive audio and video data from the corresponding terminal devices 5 according to the interface switching signal, and / or to generate corresponding input device switching signals according to the interface switching signal.

[0049] Display module 3 is configured to display the corresponding audio and video based on the audio and video data.

[0050] In application, firstly, the terminal operation signal from the input device is acquired through the terminal switching module and converted into a corresponding interface switching signal. The input device can be a mouse and / or keyboard. The terminal device can be a desktop computer, laptop computer, smartphone, tablet computer, etc. The terminal operation signal is a pre-set operation signal, which can be either pre-set at the factory or modified by the user as needed during actual use. For example, when the monitor displays the screens of two terminal devices simultaneously (e.g., a desktop computer and a laptop computer):

[0051] Example 1: Pressing the middle mouse button once triggers the terminal switching module to generate a first terminal operation signal, which can switch the mouse and keyboard to a console computer or a laptop.

[0052] Example 2: Press the "Ctrl" key and "1" key on the keyboard at the same time. The terminal switching module generates a second terminal operation signal, which can make the monitor only display the desktop computer's screen, and the mouse and keyboard also switch to the console computer.

[0053] Example 3: Press the "Ctrl" + "2" keys on the keyboard at the same time. The terminal switching module generates a third terminal operation signal, which can make the monitor only display the laptop screen, and the mouse and keyboard are also switched to control the laptop.

[0054] Example 4: Press and hold the "Alt" + "1" keys on the keyboard at the same time. The terminal switching module generates a fourth terminal operation signal, which can make the monitor display the screen of either the desktop computer or the laptop computer at the same time. The mouse and keyboard are switched to the console computer by default.

[0055] The interface switching signal can be a communication signal that is easy for the control module to identify. For example, it can be an Inter-Integrated Circuit (I2C) signal, a Recommended Standard (RS) 232 signal, or a Bluetooth signal.

[0056] Then, the control module switches to receive audio and video data from the corresponding terminal device according to the interface switching signal, and / or generates the corresponding input device switching signal according to the interface switching signal.

[0057] The interface switching signal can be a first interface switching signal that causes the control module to switch to receiving audio and video data from a desktop computer, or a second interface switching signal that causes the control module to switch to receiving audio and video data from a laptop computer. The display module then determines the audio and video data corresponding to the received audio and video data signal.

[0058] In addition, the terminal switching unit and the terminal device can be connected via Universal Serial Bus (USB) or USB Type-C cable. The terminal device transmits audio and video signals to the control module via signal cables such as High Definition Multimedia Interface (HDMI) or DisplayPort (DP).

[0059] The input device switching signal can be a first input device switching signal that connects the input device to a desktop computer, or a second input device switching signal that connects the input device to a laptop computer.

[0060] The terminal switching module connects the input device (e.g., mouse and / or keyboard) to the desktop computer based on the first input device switching signal, and connects the input device to the laptop computer based on the second input device switching signal.

[0061] Figure 2 This is a schematic diagram of a second structure of the display provided in an embodiment of this application, as shown below. Figure 2 As shown, exemplarily, the terminal switching module 1 includes a terminal switching unit 11 and a data conversion unit 12; the terminal switching unit 11 and the data conversion unit 12 are electrically connected.

[0062] The terminal switching unit 11 is configured to acquire the terminal operation signal of the input device 4 and send it to the corresponding terminal device 5, and acquire the corresponding terminal switching signal generated by the terminal device 5 according to the terminal operation signal and the preset operation / terminal switching table.

[0063] And connect the input device and the corresponding terminal device 5 according to the input device switching signal.

[0064] The data conversion unit 12 is configured to convert the terminal switching signal into an interface switching signal.

[0065] In the application, the terminal switching module first acquires the terminal operation signal from the input device (e.g., "Ctrl" key + "1" key or "Ctrl" key + "2" key, etc.) and sends it to the corresponding terminal device (e.g., a desktop computer or a laptop computer). This causes the terminal device to generate a corresponding terminal switching signal based on the terminal operation signal and the preset operation / terminal switching table within the application software. The data conversion unit converts the terminal switching signal into an interface switching signal, such as an I2C signal or an RS232 signal, so that the control module can recognize it and perform corresponding control. The application software includes mouse hook functions and keyboard hook functions to detect the connection status of the mouse and keyboard in real time and connect the keyboard and mouse to the corresponding terminal device based on the terminal operation signal.

[0066] The operation / terminal switching table contains a preset correspondence between terminal operation signals and terminal switching signals, which is stored in advance in the display's memory. For example:

[0067] When the terminal operation signal is pressing the "Ctrl" key + "1" key simultaneously, the corresponding terminal switching signal indicates that the monitor displays the desktop computer's screen.

[0068] When the terminal operation signal is pressing the "Ctrl" key + "2" key simultaneously, the corresponding terminal switching signal indicates that the monitor should display the laptop screen.

[0069] When the terminal operation signal is pressing the "Alt" + "1" keys simultaneously, the corresponding terminal switching signal indicates that the monitor displays the screen of either the desktop computer or the laptop computer at the same time.

[0070] When the terminal operation signal is pressing the middle mouse button once, the corresponding terminal switching signal indicates that the mouse and keyboard are switched to a console computer or a laptop computer.

[0071] For example, when the control module receives an interface switching signal that switches between an input device and a terminal device, it generates an input device switching signal. The terminal switching module then connects the input device and the corresponding terminal device according to the input device switching signal. For instance, the terminal switching module connects an input device (mouse and / or keyboard) and a desktop computer according to the interface switching signal, thereby enabling the input device to control the desktop computer; or it connects an input device (mouse and / or keyboard) and a laptop computer according to the interface switching signal, thereby enabling the input device to control the laptop computer.

[0072] like Figure 2 As shown, exemplarily, the terminal switching module 2 further includes a hub unit 13, which is electrically connected to the terminal switching unit 11 and the data conversion unit 12, respectively.

[0073] Hub unit 13 is configured to be electrically connected to input device 4, acquire terminal operation signals from input device 4 and send them to terminal switching unit 11, and send terminal switching signals to data conversion unit 12.

[0074] In applications, the hub unit can be a USB hub, which can be connected to a USB mouse and a USB keyboard simultaneously. The terminal switching unit connects the input device and a smart terminal respectively according to the input device switching signal, so that a set of mouse and keyboard can control multiple smart terminals respectively, and display the audio and video of multiple smart terminals on the same display.

[0075] For example, the display 100 also includes a storage module 6; the storage module is electrically connected to the control module 2.

[0076] The storage module 6 is configured to store multiple display modes of multiple terminal devices 6 on the display 100; the display modes include full-screen display mode and split-screen display mode.

[0077] In applications, when a monitor is connected to two terminal devices (such as a desktop computer and a laptop computer), there are three display modes: the monitor displays the desktop computer's screen in full screen, the monitor displays the laptop computer's screen in full screen, and the monitor displays the screens of both the desktop computer and the laptop computer simultaneously.

[0078] Figure 3 A circuit diagram of a terminal switching unit for a display provided in an embodiment of this application. (See diagram below.) Figure 3 As shown, the terminal switching unit 11 includes a PIUSB14-ALE chip. The PIUSB14-ALE chip is a multiplexed switching chip that can connect multiple input terminals and one output terminal. It can select and turn on a certain input terminal and output terminal according to the control signal.

[0079] The terminal switching unit includes a first chip U1 (i.e., the PIUSB14-ALE chip). The enable pin (EN pin) of the first chip U1 is electrically connected to the enable signal EN. The sixth and tenth pins (DM0 and DP0 pins) of the first chip U1 are electrically connected to the second and third pins (DM and DP pins) of the USB interface of the first terminal device, respectively. The fifth and eleventh pins (DM1 and DP1 pins) of the first chip U1 are electrically connected to the USB interface of the second terminal device, respectively. The second and fourteenth pins (S1 and S0 pins) of the first chip are electrically connected to the input / output (General-purpose input / output, GPIO) pins of the control module, respectively. The seventh and ninth pins of the first chip U1 are also electrically connected to the USB hub.

[0080] The fourteenth pin of the first chip U1 is also electrically connected to the fourth resistor R4 and the fifth resistor R5 to form a voltage divider circuit, which is used to provide the required voltage to the fourteenth pin of the first chip U1. For example, when the fifth resistor R5 is 0Ω, the fourteenth pin of the first chip U1 is connected to a low level; when the fifth resistor is a preset resistance value, the fourteenth pin of the first chip U1 is connected to a high level. Similarly, the second pin of the first chip U1 is electrically connected to the seventh resistor R7 and the eighth resistor R8, and the first pin of the first chip is electrically connected to the ninth resistor R9 and the eleventh resistor R11.

[0081] For example, different output results Y can be obtained based on the enable signal EN, the first control signal S0, and the second control signal S1.

[0082] Control Signal and Output Result Comparison Table

[0083] EN S1 S0 Y H X X Hi-Z L L L I0 L L H I1 L H L I2 L H H I3

[0084] In one embodiment of this application, when the enable signal EN is low, the output is a high-impedance state Hi-Z. When the enable signal EN is high, and the second control signal S1 receives a low level from the control module, it outputs result I2 based on the low level of the first control signal S0, which may indicate, for example, that the input device (keyboard or mouse) is connected to the first terminal device. When the enable signal EN is high, and the second control signal S1 receives a low level from the control module, it outputs result I3 based on the high level of the first control signal S0, which may indicate, for example, that the input device (keyboard or mouse) is connected to the second terminal device.

[0085] The first pin of the USB interface of the first terminal device is connected in series with the first diode D1, and then electrically connected to the first power supply VCC_5V, the first capacitor C1, the seventh capacitor C7, and the third pin of the second chip U2. The second and fourth pins of the second chip U2 are both electrically connected to the eighth capacitor C8 and the ninth capacitor C9. The second chip U2 is a step-down chip AZ1117FH-3.3TRG1, used to step down the external 5V power supply to 3.3V for use by the first chip U1. The first capacitor C1, the seventh capacitor C7, the eighth capacitor C8, and the ninth capacitor C9 are all used for energy storage.

[0086] Figure 4 A circuit diagram of the data conversion unit of the display provided in an embodiment of this application. Figure 4 As shown, the terminal switching unit 11 includes a PIUSB14-ALE chip, which is a conversion chip used to convert the positive and negative signals of USB into clock signals (i.e., SCL signals) and data signals (i.e., SAD signals) that the control module can recognize.

[0087] Specifically, the terminal switching unit 11 includes a third chip U3. The seventh and eighth pins of the third chip U3 are electrically connected to the USB hub to receive USB signals sent by the USB hub. The fifteenth and sixteenth pins of the third chip U3 are electrically connected to the control module to send data signals and clock signals to the control module.

[0088] The first pin of the third chip U3 is electrically connected to the seventeenth resistor R17, the sixth pin of the third chip U3 is electrically connected to the tenth capacitor C10, the ninth pin of the third chip U3 is electrically connected to the seventeenth capacitor C17 and the fifth crystal oscillator X5, and the tenth pin of the third chip U3 is electrically connected to the eighteenth capacitor C18 and the fifth crystal oscillator X5 to generate a fixed clock pulse. The first power supply VCC_5V is electrically connected to the thirteenth capacitor C13, the fourteenth capacitor C14, and the thirteenth and twentieth pins of the third chip U3 to supply power to the third chip.

[0089] like Figure 2 As shown, for example, the control module 2 includes a data receiving unit 21, a main control unit 22, and an audio / video switching unit 23.

[0090] The main control module 22 is electrically connected to the data receiving unit 21 and the audio / video switching unit 23 respectively.

[0091] The data receiving unit 21 is configured to receive interface switching signals.

[0092] The main control unit 22 is configured to generate audio and video switching signals based on the interface switching signals.

[0093] The audio / video switching unit 23 is configured to switch the reception of audio / video data from the corresponding terminal device according to the audio / video switching signal.

[0094] In the application, the data receiving unit receives the interface switching signal. The data receiving unit includes an I2C interface or an RS232 interface to receive the I2C signal or RS232 signal sent by the data conversion module.

[0095] The main control unit generates audio and video switching signals based on the interface switching signals, such as switching between receiving audio and video switching signals from a desktop computer, a laptop computer, or simultaneously receiving audio and video switching signals from both a desktop computer and a laptop computer.

[0096] The audio / video switching unit switches to receive audio / video data from the corresponding terminal device according to the audio / video switching signal. For example, it switches to receive audio / video data from a desktop computer according to the audio / video switching signal and sends it to the display module for display; or it switches to receive audio / video data from a laptop computer according to the audio / video switching signal and sends it to the display module for display; or it simultaneously receives audio / video data from both a desktop computer and a laptop computer according to the audio / video switching signal and sends it to the display module for display.

[0097] like Figure 2 As shown, by way of example, the control module 2 also includes a plurality of audio and video input units 24, all of which are electrically connected to the audio and video switching unit 23.

[0098] Multiple audio and video input units 24 are configured to receive audio and video data from multiple terminal devices 5 respectively.

[0099] In the application, each terminal device is connected to an audio / video input unit. The audio / video input of the terminal device is sent to the audio / video switching unit through the audio / video input unit, so that the audio / video signals of different terminal devices can be switched and received according to the audio / video switching signal of the audio / video switching unit.

[0100] like Figure 2As shown, for example, the control module 2 further includes a screen menu unit 25; the screen menu unit 25 is electrically connected to the main control unit 22.

[0101] The screen menu unit 25 is configured to display the terminal device 5 corresponding to the input device 1 and the display module 3, and to acquire the terminal signal manually input by the user.

[0102] In the application, the screen menu unit is used to display a message pop-up window stating "Current display screen of the first terminal device (e.g., desktop computer)" when the main control unit causes the audio-video switching unit to display audio-video data from the desktop computer; to display a message pop-up window stating "Current display screen of the second terminal device (e.g., laptop computer)" when the main control unit causes the audio-video switching unit to display audio-video data from the laptop computer; and to display a message pop-up window stating "Currently displaying the display screens of both the first and second terminal devices (e.g., desktop computer and laptop computer) simultaneously" when the main control unit causes the audio-video switching unit to display audio-video data from both the desktop computer and the laptop computer.

[0103] The screen menu unit is also used to display a message pop-up window stating "The current input device is connected to the first terminal device (e.g., a desktop computer)" when the main control unit connects the input device to the first terminal device (e.g., a desktop computer); and to display a message pop-up window stating "The current input device is connected to the second terminal device (e.g., a laptop computer)" when the main control unit connects the input device to the second terminal device (e.g., a laptop computer).

[0104] The screen menu unit is also used to directly acquire terminal signals manually input by the user, directly generate interface switching signals to the control module, control the display screen of the display module, and the terminal device connected to the input device.

[0105] For example, Figure 5 This is a schematic diagram of the structure of the multi-terminal free switching system provided in the embodiments of this application, as shown below. Figure 5 As shown, by way of example, this application provides a multi-terminal free switching system 200, including a display 100, an input device 4 and a plurality of terminal devices 5, wherein the display 100 is electrically connected to the input device 4 and the plurality of terminal devices 5 respectively.

[0106] Input device 4 is configured to input terminal operation commands or data signals.

[0107] Terminal device 5 is configured to determine the corresponding terminal operation signal according to the terminal operation instruction, or to output the corresponding audio and video data according to the data signal.

[0108] In the application, when a user inputs a preset terminal operation command, such as "Ctrl" + "1", "Ctrl" + "2", or "Alt" + "1", the terminal device determines the corresponding terminal operation signal based on the command. This causes the display module to show the screens of the first terminal device, the second terminal device, or simultaneously display the screens of both devices in a split-screen manner. For example, when the display module is a 3840*1080 monitor, the first and second terminal devices can each display a 1920*1080 screen. Additionally, the input device can receive data signals from normal user operations, allowing the terminal device to output corresponding audio and video data. When switching between the displays of multiple terminal devices connected to the monitor, the user does not need to click additional switching buttons; they can directly operate the input device, making the system convenient and providing a high level of user experience.
