[0029] With the development of display technology, LED displays have gained a significant position in the display field due to their strong scalability and long lifespan. During use, by connecting the display device to different external devices, these devices can perform various control functions. Related technologies utilize different external interfaces within the display device for connection to different external devices. For example, when external device 1 needs to control the display device, it is connected via interface 1; when external device 2 needs to control the display device, it is connected via interface 2. However, due to the numerous control functions and the wide variety of external devices that can be connected to the display device, coupled with the differences in external device types leading to varying external interface structures, the interface setup becomes cumbersome, structurally inconsistent, and ultimately, the interface utilization rate is low.

[0030] Based on this, this application provides a display screen interface switching method. An interface component is set in the display screen device to establish electrical connections with different candidate external devices. Under the mode selection operation corresponding to the target function, the target signal circuit corresponding to the target function is determined, and the target signal circuit is turned on by the interface component to realize the target function. That is, based on setting a single interface component, the target signal circuit corresponding to the external device is determined and turned on according to the access situation of the external device to realize the corresponding function, realizing the multiplexing effect of a single interface, improving the interface utilization rate while reducing the interface design cost.

The target signal circuit is turned on based on the interface component, and the target signal circuit is used to implement the target function when it is in the on state.

[0033] In some embodiments, when the target signal circuit is turned on, the first terminal device 110 sends a target transmission signal to the display device 130. The display device 130 internally implements the signal transmission link of the target transmission signal through the target signal circuit to realize the control function of the first terminal device 110 over the display device 130.

[0036] It should be noted that this application may display prompt interfaces, pop-ups, or output voice prompts before and during the collection of user data. These prompt interfaces, pop-ups, or voice prompts are used to inform the user that their data is being collected. This ensures that the application only begins the steps for collecting user data after receiving confirmation from the user regarding the prompt interface or pop-up; otherwise (i.e., without user confirmation), the steps for collecting user data end, meaning no user data is collected. In other words, all user data collected in this application is collected with the user's consent and authorization, and the collection, use, and processing of related user data must comply with the relevant laws, regulations, and standards of the relevant regions.

[0037] The display interface switching method provided in the embodiments of this application will be described in detail below. For illustrative purposes, please refer to the following: Figure 2The diagram illustrates a flowchart of a display interface switching method provided in an exemplary embodiment of this application, which includes the following steps 210 to 220.

[0038] Step 210: In response to the mode selection operation of the target function, the target signal circuit corresponding to the target function is turned on.

[0039] The display device establishes electrical connections with multiple candidate external devices through an interface component. The target function is used to indicate the function that the target external device performs on the display screen when connected to the display device through the interface component. The target external device is one of the multiple candidate external devices. The target signal circuit is used to achieve the target function when it is in the on state.

[0040] Optionally, the display screen included in the display device may be a single screen or a splicing screen; this embodiment of the application does not limit this.

[0041] Among them, "integrated screen" refers to a display screen that is a single, integral structure without any splicing process.

[0042] Among them, splicing screen refers to a display screen that is obtained by splicing multiple cabinets. Each cabinet corresponds to a sub-screen. After splicing multiple cabinets, multiple sub-screens constitute the display screen. Therefore, there are splicing seams between sub-screens.

[0043] In a schematic way, each cabinet serves as a display unit, with a single cabinet used to display a portion of the image. Thus, by stacking multiple cabinets, the complete target image can be displayed.

[0044] Optionally, the shape of the box can be implemented in various shapes, such as cuboid, cube, sphere, etc., and the embodiments of this application do not limit this.

[0045] Optionally, the splicing methods between multiple boxes include the following connection methods: 1. Rigid splicing, that is, fixing and splicing multiple boxes together using mechanical supports, for example: splicing multiple boxes together in a regular rectangle using mechanical supports.

[0046] 2. Flexible splicing, that is, using flexible LED modules or bendable LCD panels as the cabinet to achieve irregular (e.g., arc, wave, etc.) splicing.

[0047] 3. Magnetic splicing: The boxes are spliced ​​together using magnetic modules, eliminating the need for mechanical supports.

[0048] It is worth noting that the above-described splicing methods between multiple boxes are merely illustrative examples, and the embodiments of this application do not limit this.

[0049] Optionally, in the hardware structure, the transmitting board and the control board are soldered onto different printed circuit boards, or the transmitting board and the control board are soldered onto the same printed circuit board.

[0050] Optionally, the transmitting board is located in the display device, or the transmitting board is located in an external device connected to the display device; this application embodiment does not limit this.

[0051] In illustrative terms, a candidate external device refers to a terminal device used to control the display device.

[0052] As an illustration, different types of candidate external devices can implement different control functions for the display device, including the following: The first method is a network control method based on the TCP / IP protocol. That is, after the candidate external device establishes an electrical connection with the display device, the candidate external device can remotely control and manage the display device based on the TCP / IP protocol.

[0053] The second method is a control method based on the RS232 serial communication protocol. That is, after the candidate external device establishes an electrical connection with the display device, the candidate external device can achieve local control of the display device based on the RS232 serial communication protocol.

[0054] The third type: The candidate external device is equipped with a configuration tool (LED ControlTool) for the display device. After the candidate external device and the display device establish an electrical connection, the configuration tool is started and used to control the display device, such as configuring the display device's parameters, brightness correction, and splicing mapping.

[0055] It is worth noting that the above description of control functions is merely an illustrative example, and the embodiments of this application do not limit this.

[0056] Control functions based on the TCP / IP protocol are typically applicable to large-scale display scenarios, where a single external device can connect concurrently to multiple different display devices, enabling the external device to control and manage multiple display devices simultaneously. Control functions based on the RS232 serial communication protocol are typically applied to point-to-point control scenarios, where a single external device connects to only one display device and controls only one display device at a time. For example, in a conference setting, the terminal device and the projector can be connected via the RS232 protocol to achieve local control and status feedback of the projector.

[0057] Optionally, different control functions can be implemented by different external devices. For example, the first control function mentioned above can be implemented by external device a, and the second control function mentioned above can be implemented by external device b.

[0058] Optionally, different control functions can be implemented by the same external device. For example, both the first and second control functions mentioned above can be implemented by external device a. After external device a is connected to the display device, different protocols are used to achieve different control effects.

[0059] Optionally, the display device may establish electrical connections with multiple candidate external devices simultaneously, or the display device may establish electrical connections with only one candidate external device at a time.

[0060] In illustrative terms, the interface component is a physical interface located within the display device. When an external device is connected to the interface component via a network cable, an electrical connection between the external device and the display device can be established. The interface component can be implemented as an RJ45 interface (Registered Jack 45). The RJ45 interface is a standardized network interface, belonging to an 8-position modular interface (8P8C, i.e., 8 positions, 8 contacts), used to connect network cables (such as twisted-pair cables) to external devices.

[0061] In illustrative terms, mode selection operations are used to determine the target function that the display device ultimately needs to achieve; therefore, different types of mode selection operations correspond to different target functions.

[0062] In illustrative terms, the target signal circuit refers to the transmission process of the target signal within the display device after the external device sends the target transmission signal to the display device. The target transmission signal passes through different circuits within the display device to reach the final target circuit in order to achieve the corresponding target function. In other words, the functions achieved are different depending on the type of circuit through which the target signal circuit flows.

[0063] In some embodiments, the display device has one interface component, or multiple interface components. If one interface component is provided, the interface component is used to have an electrical connection with all optional candidate external devices; if multiple interface components are provided, a single interface component is used to have an electrical connection with at least two candidate external devices.

[0064] Step 220: If the target transmission signal is received from the target external device based on the interface component, the target transmission signal is transmitted through the target signal circuit.

[0065] The target signal circuit, when in the on state, is used to achieve the target function.

[0066] Indicatively, after the target signal circuit is determined, the target external device is activated, and the target transmission signal is sent to the display device through the target external device. After the interface component receives the target transmission signal, it sends the target transmission signal to the next circuit according to the target signal circuit. After passing through the loop of the target signal circuit, it reaches the final circuit structure to achieve the corresponding target function.

[0067] Indicatively, target transmission signals refer to signals sent by external devices connected to the target to achieve the target's function.

[0068] The display screen interface switching method provided in this application embodiment sets up an interface component in the display screen device to establish electrical connections with different candidate external devices. Under the mode selection operation corresponding to the target function, the target signal circuit corresponding to the target function is determined, and then the interface component conducts the target signal circuit to achieve the target function. That is, based on setting up a single interface component, the corresponding target signal circuit is determined and conducted according to the access status of the external device to achieve the corresponding function. This achieves the control effect of one interface component supporting different external devices, improving interface utilization while reducing interface design costs. In some embodiments, the selection method of the target signal circuit is described in detail. For illustrative examples, please refer to [reference needed]. Figure 3 It illustrates a flowchart of a display interface switching method provided in an exemplary embodiment of this application, such as... Figure 3 As shown, step 210 also includes steps 211 and 212, and the method includes the following steps.

[0069] Step 211: Determine the target operation signal based on the mode selection operation.

[0070] Indicatively, the target operation signal is an operation signal generated based on the mode selection operation.

[0071] As an illustration, the target operation signals corresponding to different mode selection operations are also different.

[0072] Step 212: Determine the target pin from multiple input / output pins based on the target operation signal.

[0073] The target pins correspond to the target functions.

[0074] The display screen device also includes a control chip, which has multiple input / output pins, each used to control different signal circuits. As an illustration, the display device includes a control chip (e.g., an ARM chip) to coordinate the circuit structure of the target signal circuit. That is, the display device also includes multiple other circuit structures, each of which includes a corresponding chip. The control chip selects at least one of the circuits to enable it to transmit the target signal.

[0075] To illustrate, taking an ARM chip as an example, an ARM chip has general purpose input / output (GPIO) ports. Different GPIOs (i.e., input / output pins) are used to control different target signal circuits. Therefore, after the corresponding target operation signal is generated according to the mode selection operation, the ARM chip determines the corresponding GPIO pin to be activated based on the received target operation signal.

[0076] In some embodiments, the display device displays a mode selection area with multiple candidate function options; upon detecting a trigger operation in response to a target function option, it is determined that a mode selection operation has been received.

[0077] Indicatively, the display device is equipped with an on-screen menu adjustment method (OSD), that is, the display parameters are adjusted by overlaying menus or information on the screen. In this embodiment, a mode selection area is displayed on the display device, which shows candidate function options supported by different candidate external devices. When a trigger operation for a target function option is received, the trigger operation is used as a mode selection operation.

[0078] This is illustrative; please refer to it. Figure 4 This illustrates a schematic diagram of an OSD menu provided in an exemplary embodiment of this application, such as... Figure 4 As shown, the current display mode selection area 400 displays function options corresponding to function 1, function options corresponding to function 2, and function options corresponding to function 3.

[0079] In some embodiments, the display assembly includes a button assembly; upon detecting a button trigger operation in response to the button assembly, it is determined that a mode selection operation has been received.

[0080] As an illustration, the display device is equipped with a button component. By performing different button operations on the button component, the corresponding target function is determined. For example, triggering the button component once indicates selecting function 1, and triggering the button component twice indicates selecting function 2.

[0081] Step 213: Turn on the target signal circuit based on the target pin.

[0082] In some embodiments, the display device further includes a signal conversion chip; the signal flow direction of the signal conversion chip is determined based on the target pin; and the target signal circuit is determined based on the signal flow direction.

[0083] As an illustration, the display device includes a switch chip, which is a signal conversion chip. A switch chip is a core component of network devices, primarily responsible for forwarding data packets between different ports. This chip is widely used in Ethernet switches, routers, and other devices, responsible for efficiently managing and transmitting network data.

[0084] In this embodiment, if the Switch chip has three selection pins (A, B, C), and these selection pins are connected to different other chips respectively, for example, pin A is connected to other Switch chips, pin B is connected to an ARM chip, and pin C is connected to a PHY chip, then the ARM needs three GPIO pins to control the high and low levels of these three pins respectively, thereby selecting different input / output channels so that the signal conversion chip can implement different signal transmission links according to different target signal circuits after receiving the target output signal.

[0085] In some embodiments, the signal conversion chip includes a first conversion chip and a second conversion chip, the target function is a remote control function implemented based on a first type of protocol, and the signal flow direction includes a first signal direction and a second signal direction; when the second conversion chip receives a first level signal sent by the target pin, the first signal direction is determined based on the first level signal; when the first conversion chip receives a second level signal sent by the target pin, the second signal direction is determined based on the second level signal; wherein, the first signal direction is used to indicate that after the second conversion chip receives the target transmission signal sent by the interface component, it sends the target transmission signal to the first conversion chip, and the second signal direction is used to indicate that after the first conversion chip receives the target transmission signal sent by the second conversion chip, it sends the target transmission signal to the control chip.

[0086] This is illustrative; please refer to it. Figure 5 This illustrates a schematic diagram of the internal architecture of a display device provided in an exemplary embodiment of this application, such as... Figure 5 As shown, the display device includes a control chip, a first conversion chip, a second conversion chip, a PHY chip, a serial communication interface (USB), and a sending card.

[0087] In this embodiment, if the target function is a remote function based on the TCP / IP protocol, the control chip activates GPIO pin 1 as the target pin. It sends a first-level signal (including a high-level signal or a low-level signal) to the second conversion chip via GPIO pin 1 as enable signal 1, and sends a second-level signal (including a high-level signal or a low-level signal) to the first conversion chip via GPIO pin 1 as enable signal 2. Upon receiving enable signal 1, the second conversion chip, and upon receiving enable signal 2, the first conversion chip conducts the circuit loop 1 formed by the interface component, the second conversion chip, the first conversion chip, the PHY chip, and the control chip. If the interface component sends the target transmission signal from the external device to the second conversion chip via a network signal line, the second conversion chip sends the target transmission signal to the first conversion chip via the network signal line. The first conversion chip then sends the target transmission signal to the control chip via the PHY chip, thus realizing the remote function based on the TCP / IP protocol.

[0088] Among them, the PHY (Physical Layer) module / chip is the physical layer chip in network communication, which is mainly responsible for converting the differential signals of the network interface (e.g., RJ45 network port) into digital signals.

[0089] In some embodiments, the signal conversion chip includes a second conversion chip, the target function is a local control function implemented based on a second type of protocol, and the signal flow direction includes a third signal direction; when the second conversion chip receives a third level signal sent by the target pin, the third signal direction is determined based on the third level signal, wherein the third signal direction is used to indicate that the second conversion chip sends the target transmission signal to the control chip after receiving the target transmission signal sent by the interface component.

[0090] In this embodiment, if the target function is local control based on the S232 protocol, the control chip activates GPIO pin 2 as the target pin and sends a third-level signal (including a high-level signal or a low-level signal) to the second conversion chip as an enable signal 3 through GPIO pin 2. Upon receiving the enable signal 3, the second conversion chip conducts the circuit loop 2 formed by the interface component, the second conversion chip, and the control chip. If the interface component sends the target transmission signal sent by the external device to the second conversion chip through the network signal line, the second conversion chip sends the target transmission signal to the control chip through a Universal Asynchronous Receiver / Transmitter (UART), thus realizing the remote function based on the S232 protocol.

[0091] UART is an asynchronous serial communication interface used to transmit data via serial communication.

[0092] In some embodiments, the signal conversion chip includes a first conversion chip, a second conversion chip, and a transmitting card. The target function is to implement control functions for the display device based on a configuration tool. The signal flow direction includes a fourth signal direction and a fifth signal direction. When the second conversion chip receives a fourth-level signal sent by the target pin, it determines a fourth signal direction based on the fourth-level signal. When the first conversion chip receives a fifth-level signal sent by the target pin, it determines a fifth signal direction based on the fifth-level signal. The fourth signal direction is used to indicate that the second conversion chip sends a target transmission signal to the first conversion chip after receiving the target transmission signal sent by the interface component, and the fifth signal direction is used to indicate that the first conversion chip sends a target transmission signal to the transmitting card after receiving the target transmission signal sent by the second conversion chip.

[0093] In this embodiment, if the target function is a control function based on the configuration tool, the control chip activates GPIO pin 3 as the target pin. A fourth level signal (including a high or low level signal) is sent to the second conversion chip via GPIO pin 3 as an enable signal 4. A fifth level signal (including a high or low level signal) is also sent to the first conversion chip via GPIO pin 3 as an enable signal 5. Upon receiving enable signal 4, the second conversion chip receives enable signal 4, and upon receiving enable signal 5, the first conversion chip activates the circuit loop 3 formed by the interface component, the second conversion chip, the first conversion chip, and the sending card. If the interface component sends the target transmission signal from the external device to the second conversion chip via a network signal line, the second conversion chip sends the target transmission signal to the first conversion chip via the network signal line. The first conversion chip then sends the target transmission signal to the sending card via USB, thus realizing the control function based on the configuration tool.

[0094] In some embodiments, the interface signal sent by the target external device is received based on the mode selection operation; the target signal circuit corresponding to the target function is determined based on the level type corresponding to the interface signal.

[0095] In a schematic representation, based on the hardware interface design of the LED display all-in-one machine, an ARM module is used to detect the level of three interface signals, automatically determining whether the input signal is TCP / IP, USB, or RS232, and automatically switching the direction of the switch signal flow to achieve automatic interface multiplexing and switching. For example, USB uses a 3.3Vpp difference between D+ and D-, RS232 uses a ±12V level voltage, while TCP / IP has a difference of approximately 1Vpp. USB and RS232 can be distinguished using different physical differential lines in the hardware design.

[0096] This is illustrative; please refer to it. Figure 6This illustrates a schematic diagram of the internal architecture of a display device provided in an exemplary embodiment of this application, such as... Figure 6 As shown, when the interface component receives the interface signal (i.e., the target transmission signal) sent by the target external device, it directly performs level detection on the target transmission signal and drives the control chip to determine the corresponding target signal circuit based on the detected level result.

[0097] This is illustrative; please refer to it. Figure 7 This illustrates a schematic diagram of the internal architecture of a display device provided in an exemplary embodiment of this application, such as... Figure 7 As shown, when the button component receives a button trigger operation, it sends the level signal corresponding to the target function to the control chip according to the button trigger operation, so as to drive the control chip to determine the corresponding target signal circuit.

[0098] This is illustrative; please refer to it. Figure 8 It illustrates a schematic diagram of an RJ45 interface provided in an exemplary embodiment of this application, such as... Figure 8 As shown, pins 3 and 6 are used for RS232 interface protocol transmission, and pins 1 and 2 are used for USB interface protocol transmission. The RJ45 interface uses different pins to transmit signals according to different target signals, facilitating subsequent determination of the conduction state of the target signal circuit.

[0099] The display screen interface switching method provided in this application embodiment sets up an interface component in the display screen device to establish electrical connections with different candidate external devices. Under the mode selection operation corresponding to the target function, the target signal circuit corresponding to the target function is determined, and the target signal circuit is turned on by the interface component to realize the target function. That is, based on setting up a single interface component, the target signal circuit corresponding to the external device is determined and turned on according to the access situation of the external device to realize the corresponding function, realizing the multiplexing effect of a single interface, improving the interface utilization rate while reducing the interface design cost.

[0100] This is illustrative; please refer to it. Figure 9 This illustration shows a schematic diagram of a display interface switching method provided in an exemplary embodiment of this application, such as... Figure 9 As shown, the display device is connected to three external devices: device 1, device 2, and device 3. For the mode selection operation of the target function (e.g., the function corresponding to device 1), the control chip determines the target signal circuit corresponding to the target function. Thus, after device 1 is started, device 1 sends a target transmission signal to the interface component. The target transmission signal reaches the final target circuit structure through the target signal circuit to realize the corresponding target function.

[0101] In this embodiment, the RJ45 hardware interface is used to implement the RS232, TCP / IP, and USB three-in-one debugging function. With an ARM main control chip with integrated protocol conversion capability as the core, and a dedicated interface conversion chip switch chip and a network port terminal adapter module (e.g., PHY module) expansion circuit, the hardware design realizes bidirectional data conversion and independent adjustment of the three interfaces through signal splitting and protocol pass-through.

[0102] In this embodiment, the GPIO of the ARM main control chip is used to control the switching signal of the Switch chip (1-to-2 signal conversion chip).

[0103] In one implementation, an OSD menu is placed on the ARM main control chip. When an external device needs to control USB, TCP / IP, or RS232 protocol functions via the RJ45 interface, the corresponding configuration can be selected through the menu on the display screen. For example, when controlling the screen's sending card module via PC-side LCT software, the OSD menu is switched to USB mode. The ARM module then controls the Switch2 chip to switch the signal to Switch1, and then controls the Switch1 chip to send the signal to the sending card. The USB interface and the sending card are physically connected, enabling control of the USB signal channel. Another example: when an external central control device needs to use RJ45 to access TCP / IP protocol control, the OSD menu can be switched to TCP / IP mode. The ARM module then controls the Switch2 and Switch1 chips to send network signals to the ARM module. Yet another example: when an external central control device needs to use RS232 protocol control, the OSD menu can be switched to RS232 mode. The ARM module then controls the Switch2 chip to send central control signals to the ARM module.

[0104] In other words, when USB mode is selected via the OSD menu, the ARM chip controls the GPIO pins to cause Switch chip 2 to send signals to Switch chip 1, and then controls the GPIO pins to cause Switch chip 1 to send signals to the USB port. When RS232 mode is selected via the OSD menu, the ARM chip controls the GPIO pins to cause Switch chip 2 to send signals to the ARM chip's UART. Similarly, when TCP / IP mode is selected via the OSD menu, the ARM chip controls the GPIO pins to cause Switch chip 2 to send signals to Switch chip 1, and then controls the GPIO pins to cause Switch chip 1 to send signals to the PHY module, which in turn sends signals to the ARM chip.

[0105] In another implementation, 1. The ARM main control board has buttons and indicator LEDs, as shown in the diagram above. When an external device needs to control USB, TCP / IP, or RS232 protocols via the RJ45 interface, the corresponding interface protocol mode can be switched by pressing and holding the button for 3 seconds. The success of the switch can be indicated by the number of flashes of the indicator light. For example, when the PC-side LCT software needs to control the screen's sending card module, and the external central control device uses RJ45 to access the TCP / IP protocol or RS232 protocol for control, pressing and holding the button for 3 seconds switches the currently used interface protocol mode. At this time, the ARM module controls the Switch2 and Switch1 chips to allow external signals to flow into the corresponding modules.

[0106] In other words, pressing and holding the button for 3 seconds causes the LED to flash once. Therefore, when the LED flashes twice via the button, the ARM chip controls the GPIO pins to send a signal from Switch Chip 2 to Switch Chip 1, and then controls the GPIO pins to send a signal from Switch Chip 1 to the USB. When the LED flashes three times via the button, the ARM chip controls the GPIO pins to send a signal from Switch Chip 2 to the ARM chip's UART. When the LED flashes once via the button, the ARM chip controls the GPIO pins to send a signal from Switch Chip 2 to Switch Chip 1, and then controls the GPIO pins to send a signal from Switch Chip 1 to the PHY module, which in turn sends a signal to the ARM chip.

[0107] The display screen interface switching method provided in this application embodiment sets up an interface component in the display screen device to establish electrical connections with different candidate external devices. Under the mode selection operation corresponding to the target function, the target signal circuit corresponding to the target function is determined, and the target signal circuit is turned on by the interface component to realize the target function. That is, based on setting up a single interface component, the target signal circuit corresponding to the external device is determined and turned on according to the access situation of the external device to realize the corresponding function, realizing the multiplexing effect of a single interface, improving the interface utilization rate while reducing the interface design cost.
