[0054] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0055] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0056] Visible light wireless communication, also known as "light fidelity," is a wireless transmission technology that uses the visible light spectrum (such as the light emitted by a light bulb) for data transmission. By applying visible light wireless communication technology, light-emitting devices can be controlled to emit high-speed flashing signals that are invisible to the naked eye to transmit information. This technology can reach the range of light, and devices using this technology can access the internet without conventional wired connections or wireless connections (such as WiFi (Wireless Fidelity)).

[0057] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a display device. The display device may include a display device housing 11, a display module 12, and a visible light wireless communicator 13. The display module 12 is located within the display device housing 11 and may include a display module and a backlight assembly. The visible light wireless communicator 13 may include a visible light wireless communication controller 131 and a light-emitting device 132. The visible light wireless communication controller 131 and the light-emitting device 132 may be located outside the display device housing 11 so that the light-emitting device 132 can emit light externally. The display device may also include a control component, which may be located within the display device housing 11 and is used to control the display module and the visible light wireless communicator 12.

[0058] When using this display device to transmit visible light wireless data, the control component in the display module can obtain the data to be transmitted and transmit it to the visible light wireless communication controller 131 in the visible light wireless communicator 13. The visible light wireless communication controller 131 can then control the light emitting device 132 to flash to transmit the visible light wireless communication data. For example, turning on the light emitting device 132 can represent a 1, while turning off can represent a 0. This allows information to be transmitted by rapidly turning on and off.

[0059] However, the structure of this display device is relatively complex and not aesthetically pleasing.

[0060] Figure 2 This is a structural schematic diagram of a display device shown in an embodiment of the present application. The display device 20 includes: a display module 21 and a visible light wireless communication controller 22. The display module 21 includes a backlight assembly 211. The backlight assembly 211 includes multiple light-emitting devices. The visible light wireless communication controller 22 is connected to the backlight assembly 211.

[0061] The visible light wireless communication controller 22 is used to obtain data to be transmitted.

[0062] The visible light wireless communication controller 22 is further configured to control the plurality of light emitting devices in the backlight assembly 211 to turn on and off based on the data to be transmitted, so as to emit the first visible light wireless communication data.

[0063] It should be noted that the visible light wireless communication controller 22 controls the turning on and off of the light-emitting device here, which may mean that the visible light wireless communication controller 22 controls the light-emitting device to turn on and off continuously for multiple times, and sends the first visible light wireless communication data through the multiple turning on and off.

[0064] In addition, the data to be transmitted may be data that the display device wants to transmit to other devices. The data to be transmitted may be generated by the visible light wireless communication controller 22, or may be part or all of the data received by the visible light wireless communication controller 22. Alternatively, the data to be transmitted may be data obtained by the visible light wireless communication controller 22 after processing the received data. The embodiments of the present application are not limited to this. Specifically, the data to be transmitted may include some operating data of the display device itself, such as the display program list and fault data of the display device, and may also include information request data (which may request data from other external devices).

[0065] In summary, the display device provided by the embodiments of the present application uses a visible light wireless communication controller in the display device to obtain data to be transmitted, and controls the on and off of multiple light-emitting devices in the backlight assembly based on the data to be transmitted to emit first visible light wireless communication data. This allows the transmission of visible light wireless communication data through the backlight assembly inherent in the display device, without the need to install an additional light bulb on the display device housing. This solves the problem of complex display device structures in related technologies and simplifies the display device structure. Furthermore, the display device is more aesthetically pleasing.

[0066] In addition, since the light-emitting devices in the backlight assembly can flash as quickly as light bulbs in related technologies when transmitting visible light wireless communication data and are not easily detected by the human eye, the visible light wireless communication data transmission function can be realized through the display device without affecting the user experience.

[0067] In an exemplary embodiment, Figure 3 This is a block diagram of another display device provided in an embodiment of the present application. The display module 21 in the display device may include a display panel 212 and a backlight assembly 211 located on the back of the display panel 212. The backlight assembly 211 is used to provide a light source to the display panel 212, and the display panel 212 is used to emit an image light beam to the outside under the illumination of the light source.

[0068] It should be noted that current display devices include a backlight driver control chip (Driver IC). This backlight driver control chip can control the light-emitting devices in different areas of the backlight assembly 211 to emit light beams of different brightnesses to cooperate with the display panel for display. For example, the multiple light-emitting devices in the backlight assembly 211 can be divided into ten areas, and the backlight driver control chip can control these ten areas to emit light of different brightnesses. However, the structure of this backlight driver control chip is relatively simple, making it difficult to achieve more complex control of the light-emitting devices. For example, this backlight driver control chip cannot realize the function of controlling the light-emitting devices to turn on and off to transmit visible light wireless communication data.

[0069] To address this issue, the display device provided in an embodiment of the present application includes a visible light wireless communication controller that can be used to control the on and off of multiple light-emitting devices in the backlight assembly 211 to transmit visible light wireless communication data. The visible light wireless communication controller can have the function of controlling the on and off of the light-emitting devices to transmit visible light wireless communication data.

[0070] In an embodiment of the present application, the visible light wireless communication controller can have multiple implementations. For example, in an exemplary embodiment, the visible light wireless communication controller 22 may include an instruction set-based display controller 221. The instruction set-based display controller 221 is a controller that can have multiple functions, and the functions of the controller can be pre-set as needed. In an embodiment of the present application, the instruction set-based display controller 221 can have multiple architectures. For example, the instruction set-based display controller 221 can be an Advanced RISC Machines (ARM) architecture, a microprocessor without internal interlocking pipeline stages (Million Instructions Per Second, MIPS) architecture, or a fifth-generation reduced instruction set computer (RISC-V) architecture.

[0071] Among them, the ARM architecture is a 32-bit reduced instruction set processor architecture. The ARM architecture is widely used in many embedded system designs and has the characteristics of low power consumption and energy saving. The MIPS architecture is a simple and highly scalable RISC architecture. The RISC-V architecture is an open source instruction set architecture based on the reduced instruction set principle. Compared with most instruction sets, the RISC-V instruction set can be freely used for various purposes, allowing anyone to design, manufacture and sell RISC-V chips and software. The design of the RISC-V architecture makes it suitable for modern computing devices (such as warehouse-scale cloud computers, high-end mobile phones and tiny embedded systems), and the RISC-V architecture also has a large number of supporting software.

[0072] Figure 4 yes Figure 3 The structural block diagram of the display controller 221 based on the instruction set shown in FIG. Figure 5 This is a system solution architecture diagram of the display device provided in the embodiment of the present application, please refer to Figure 3 、 Figure 4 and Figure 5 In the embodiment of the present application, the instruction set-based display controller 221 is used to obtain display backlight control data. The instruction set-based display controller 221 is also used to control multiple light-emitting devices based on the display backlight control data to realize the backlight function of the display device when displaying an image (this function can be called a display backlight control function). That is, the instruction set-based display controller 221 can also control the backlight assembly 211 to cooperate with the display panel to jointly realize the display function of the display device. In the related art, the display backlight control function is implemented by a backlight driver control chip (Driver IC). In the embodiment of the present application, the display backlight control function is integrated into the instruction set-based display controller 221, and the instruction set-based display controller 221 is used to implement the instruction set-based display controller 221. Therefore, in the display device provided in the embodiment of the present application, a backlight driver control chip (Driver IC) may not be provided. In this way, the display device can be provided with an additional visible light wireless communication data transmission function without adding new devices, which is beneficial to the integration and integration of devices in the display device.

[0073] The display controller 221 based on the instruction set can obtain display data and obtain display backlight control data based on the display data.

[0074] In an exemplary embodiment, the display controller 221 based on the instruction set can be used to compress the data to be transmitted to obtain compressed data to be transmitted, so as to reduce the amount of data to be transmitted, thereby reducing the transmission pressure of visible light wireless communication data. Exemplarily, the display controller 221 based on the instruction set can encode the data to be transmitted by streaming media encoding to achieve the effect of compressing the data to be transmitted. For example, by encoding the data to be transmitted by h.265 encoding, the data to be transmitted can be compressed to 1 / 300 of the original data volume. Of course, the display controller 221 based on the instruction set can also compress the data to be transmitted in other ways, and the embodiments of the present application are not limited to this.

[0075] The instruction set-based display controller 221 is further configured to perform visible light wireless communication encoding on the compressed data to be transmitted to obtain visible light wireless communication control data. This visible light wireless communication encoding (LiFi encoding) is used to convert the compressed data to be transmitted into visible light wireless communication control data, which is data that the backlight assembly 211 can recognize and control the light-emitting device based on. The method of this visible light wireless communication encoding can be pre-set and is not limited in this embodiment of the present application.

[0076] After acquiring the visible light wireless communication control data, the instruction set-based display controller 221 can transmit the visible light wireless communication control data to the backlight assembly 211. The backlight assembly 211 is configured to control the turning on and off of the plurality of light-emitting devices under the control of the visible light wireless communication control data, thereby transmitting the first visible light wireless communication data. In other words, in the display device provided in the embodiment of the present application, when transmitting the visible light wireless communication data, the instruction set-based display controller 221 can sequentially perform compression encoding and visible light wireless communication encoding on the data to be transmitted.

[0077] The above encoding function can be obtained by Figure 4 It is implemented by the codec module in .

[0078] In an exemplary embodiment, please refer to Figure 6 , Figure 6 It is a structural schematic diagram of a backlight assembly provided in an embodiment of the present application, wherein the backlight assembly 211 may include multiple partitions q1, each partition q1 includes at least one light-emitting device, which can emit light. Exemplarily, the light-emitting device may include a light-emitting diode (LED).

[0079] The visible light wireless communication controller is used to perform partition control on the multiple partitions q1 (the partition control may mean that the visible light wireless communication controller can control the opening and closing of the light-emitting devices in the multiple partitions q1 respectively), so that the multiple partitions q1 can be turned on and off independently. In this case, each partition can be used to transmit one bit of coded data. Based on the number of light-emitting devices in each partition, the base of the coded data transmitted by each partition may be different. For example, when each partition includes only one light-emitting device, each partition can be used to transmit one bit of binary coded data. When each partition includes more light-emitting devices, each partition can be used to transmit higher base coded data (such as decimal, hexadecimal, etc.). Compared with the related art of transmitting visible light wireless communication data by flashing a light bulb, the control method provided in the embodiment of the present application can greatly improve the transmission rate of the display device for transmitting visible light wireless communication data.

[0080] It should be noted that the above-mentioned backlight assembly 211 can be a direct-type backlight assembly, which can realize partition control to improve the transmission rate of visible light wireless communication data, but the backlight assembly 211 provided in the embodiment of the present application can also be a side-entry backlight assembly, and the embodiment of the present application does not limit this.

[0081] When the instruction set-based display controller 221 in the display device provided in the embodiment of the present application is a RISC-V architecture display controller, Figure 4 The central processing unit (CPU) in the system may include a 5-stage pipeline RISC-V micro-architecture processor. The 5-stage pipeline RISC-V micro-architecture processor has the advantage of high working efficiency. In this processor, five instructions can be in different processing stages at the same time, which can significantly increase the processor's instruction throughput rate.

[0082] Of course, the central processing unit in the instruction set-based display controller provided in the embodiment of the present application can also have other structures, and the embodiment of the present application is not limited to this. In this structure, the instruction set-based display controller 221 can be called a RISC-V architecture-based control image processing driver chip (RISC-V Integrated Driver IC, RIDI).

[0083] In an exemplary embodiment, Figure 7 As shown, Figure 7 FIG1 is a schematic diagram of a backlight driver circuit in a display device according to an embodiment of the present application. The backlight assembly further includes a plurality of light-emitting device driver chips C1, which can be used to drive the light-emitting devices in the backlight assembly to emit light. For example, when the light-emitting devices include light-emitting diodes, the light-emitting device driver chip C1 can be a light-emitting diode driver chip (LED Driver IC).

[0084] The multiple light-emitting devices in the backlight assembly 211 constitute multiple light-emitting device groups. Each light-emitting device group includes at least one light-emitting device. The multiple light-emitting device groups are connected to multiple light-emitting device driver chips in a one-to-one correspondence. In other words, one light-emitting device driver chip c1 can be used to control the on and off of at least one light-emitting device. To simplify the structure and save costs, each light-emitting device group can include multiple light-emitting devices (e.g., ten, twenty, thirty,..., one hundred, etc.).

[0085] The display device provided in the embodiment of the present application can control the multiple light-emitting device driver chips c1 through various control structures to realize the function of controlling the light-emitting devices to send visible light wireless communication data.

[0086] A structure can be Figure 7As shown, the display device further includes a backlight control chip 23, which is connected to multiple light-emitting device driver chips c1. In this structure, the backlight control chip 23 can control the multiple light-emitting device driver chips c1, thereby controlling the turning on and off of the light-emitting devices in each light-emitting device group.

[0087] The instruction set-based display controller 221 is connected to the backlight control chip 23 . The instruction set-based display controller 221 is used to control the plurality of light-emitting device driving chips c1 through the backlight control chip 23 .

[0088] This control method can be used in display devices in related technologies, that is, it is possible to control the turning on and off of the light-emitting devices in the light-emitting device group to send visible light wireless communication data without changing the backlight driving circuit in the related technology.

[0089] Please refer to Figure 8 , Figure 8 This is a structural diagram of another backlight driving circuit in the display device provided in an embodiment of the present application, wherein the display device also includes a shift register 24, and the instruction set-based display controller 221 is connected to the shift register 24 through a clock control line cp and a data line D0.

[0090] The shift register 24 includes a plurality of delay triggers 241 connected in series, each of the delay triggers 241 including two input terminals (i1 and i2) and an output terminal o. An input terminal i1 of the delay trigger 241 is connected to the clock control line cp, another input terminal i2 of the first delay trigger 241 among the plurality of delay triggers is connected to the data line D0, and another input terminal i2 of the other delay triggers 241 except the first delay trigger 241 is connected to the output terminal o of the previous delay trigger 241.

[0091] The plurality of light emitting device driving chips c1 are respectively connected to the output terminals o of the plurality of delay flip-flops (D flip-flops) 241 .

[0092] In this structure, multiple light emitting device driver chips c1 can be controlled separately through the multiple delay triggers 241, and the structure is not affected by Figure 7 The output frequency limitation of the backlight control chip in the structure shown can control multiple light-emitting device driver chips c1 at a higher frequency to improve the transmission rate of visible light wireless communication data.

[0093] The shift register 24 is a flip-flop-based device that operates under multiple identical timing pulses. Data is input into the device in parallel or serial mode, and then shifted one bit left or right with each timing pulse. The shift register may include multiple edge-triggered D flip-flops, with the output of each D flip-flop connected to the input of the next. Because there is a delay between the rising edge of the clock signal being applied to the D flip-flop and the new state being established at the output, when the clock signal is applied to multiple D flip-flops simultaneously, each D flip-flop receives the register value output by the previous D flip-flop after the clock is triggered. For example, initially the input of the first D flip-flop is a high level 1, while the inputs of other D flip-flops are all in a low level 0 state. When the first clock arrives, the first D flip-flop will be triggered, and the high level will be sent to the output of the first D flip-flop. The state of the output of the first D flip-flop is 1. The output of the first D flip-flop is connected to the input of the second D flip-flop, that is, the input state of the second D flip-flop is a high level 1 at this time. When the second clock arrives, this high level state will be sent to the output of the second flip-flop, and so on, until this high level signal is sent out of all D flip-flops.

[0094] In an exemplary embodiment, the display device further includes a frequency multiplier 25, which is located on the clock control line cp and the data line D0 between the instruction set-based display controller 221 and the shift register 24. The frequency multiplier 25 can multiply the output frequency, thereby controlling the light-emitting device to turn on and off at a faster frequency, further improving the transmission rate of visible light wireless communication data.

[0095] In addition, this solution facilitates integration because the shift register can be composed of many MOSFETs, which can form the intellectual property (IP) of the hardware module and be embedded in the display module, which is conducive to integration.

[0096] The above embodiment illustrates how the display device provided in the embodiment of the present application sends visible light wireless communication data. The following describes how the display device receives data.

[0097] Please refer to Figure 5 The display device further includes a photosensitive receiver 26 and an analog-to-digital converter 27. The photosensitive receiver 26 is used to receive the second visible light wireless communication data and convert the second visible light wireless communication data into an electrical signal. The conversion process is a photoelectric conversion process.

[0098] The digital-to-analog converter 27 is used to convert an electrical signal (the electrical signal is an analog electrical signal) into a digital signal.

[0099] The display controller 221 based on the instruction set is used to obtain the digital signal and control the display device based on the digital signal. Based on the different types of the digital signal, the display controller 221 based on the instruction set can perform different controls.

[0100] In an exemplary embodiment, the display controller 221 based on the instruction set is used to control the display panel 212 and the backlight assembly 211 based on the image data when the digital signal includes image data, so as to realize the image display function of the display device.

[0101] Figure 4 The data encoding and decoding module in the DAC 27 can be used to decode the digital signal (the digital signal can be data encoded by streaming media) converted by the DAC 27 for easy reading.

[0102] In an exemplary embodiment, the data receiving process may include: a photosensitive receiver 26 may be configured to receive visible light wireless communication data transmitted by an external visible light wireless communication light source. After receiving the visible light wireless communication data, the photosensitive receiver 26 transmits the received data to a digital-to-analog converter 27 for conversion of the analog signal into a digital signal. After obtaining the digital signal, the signal is transmitted to the instruction set-based display controller 221, where the interface module decodes the data. The data processing module may process different types of data based on the data type in the digital signal. For example, the data processing module may transmit image data to the image processing module for image processing, and control data to the control module. After processing by the display control module, the data is transmitted to the timing control module (which may include the TCON module (screen driver module)). The timing control module then controls the display panel to display the image.

[0103] The process of sending data may include: placing the image data to be sent, or the control data used for interaction, into a storage space (such as RAM (random access memory)) by identifying the user's operation (such as the user's operation through the touch screen or the operation issued by the external control terminal). The data processing module can read the information from the storage space, encode the image data, and encode the mutual control information. After the encoding is completed, it is sent to the control timing generation module. This unit will generate a backlight drive control signal based on the encoded information. This signal will be transmitted to the backlight control module, and the backlight control module will control the backlight assembly and control the light-emitting device to turn on and off to realize the transmission of visible light wireless communication data.

[0104] In an exemplary embodiment, when the digital signal includes image data, the instruction set-based display controller 221 is configured to control the display panel and backlight assembly 211 based on the image data to implement the image display function of the display device. Simultaneously, the instruction set-based display controller 221 controls the on / off switching of multiple light-emitting devices in the backlight assembly 211 based on the data to be transmitted, thereby transmitting first visible light wireless communication data. Because the instruction set-based display controller 221 can control the on / off switching of the multiple light-emitting devices in the backlight assembly 211 at a high frequency, which is imperceptible to the human eye, the multiple light-emitting devices can be simultaneously controlled to turn on and off to transmit visible light wireless communication data while displaying a normal image.

[0105] In an exemplary embodiment, the display device further includes a speaker, and the display controller based on the instruction set is configured to transmit audio data to the speaker when the digital signal includes audio data.

[0106] In an exemplary embodiment, the display device further includes a data processing chip and a data receiving component; the data receiving component includes a wired transmission module and a wireless transmission module. The wired transmission module is configured to transmit data via a wired connection, and the wireless transmission module is configured to transmit data via a wireless connection (such as a conventional wireless connection, such as a WiFi connection or a Bluetooth connection). In other words, the display device provided in the embodiments of the present application may also include a conventional data connection module to implement a conventional connection and receive or send data via the conventional connection, but the embodiments of the present application are not limited thereto.

[0107] The above embodiment provides a solution for setting an instruction set-based display controller in a display device to implement various visible light wireless communication functions, but the display device provided in the embodiment of the present application can also implement various visible light wireless communication functions through other solutions.

[0108] Exemplarily, a display device includes a backlight assembly controller and a visible light wireless communication controller. The backlight assembly controller is used to control the backlight assembly to implement a backlight function when the display device displays an image. In this structure, the backlight assembly controller can be a controller (such as a driver IC) used in related art to control the backlight assembly to implement display backlight control functions. This structure implements various visible light wireless communication functions by additionally providing a visible light wireless communication controller in the display device.

[0109] Below Figure 4 Some modules in the following are described:

[0110] Data processing module: can be used for data analysis and processing, identifying data types, reported data (such as touch) triggered by clock interrupts, etc. The data processing module can interact with other modules.

[0111] For example, in the process of receiving data by the instruction set-based display controller 221, after the data encoding and decoding module completes decoding of the streaming media data, it can call the data processing module through the bus to separate the data, and distinguish the data based on the data type by comparing and verifying the information such as the packet header and frame header of different data protocols to obtain image data, audio data, and control data, and send different types of data to different modules for further processing in a broadcast manner through the bus. Among them, the image data can be sent to the image processing module, and the audio data can be sent to the external interface of the instruction set-based display controller 221 to be transmitted to the speaker of the display device; the control data can be transmitted to other interfaces or control modules for interactive control with people.

[0112] The data processing module also plays a role in the data transmission process. After the system starts the read thread (for example, it can be triggered by an application within the CPU), the data processing module will read data from the memory, then convert the image data and touch data into a specified format (adding information such as packet headers and frame headers) so that the terminal can recognize it. It then calls the codec module through the bus to perform streaming media encoding. After encoding is complete, the data processing module will call the algorithm program within the CPU, which will re-encode the data after streaming media wireless communication through visible light wireless communication. The data processing module transmits the encoded data to the timing control module, which generates the drive signal for controlling the backlight and transmits it to the light-emitting device driver chip.

[0113] In addition, the data processing module can also generate display timing control data based on the image size, refresh rate, and application instructions (the display timing control data (timing) can achieve the required display mode), and then send the display timing control data to the timing control module, which controls the gate lines and source lines for scanning and display. For example, the resolution of the display data is FHD (such as 1920*1080) and the frame rate is 60 Hz. Then, the application will adjust the display mode according to the user's selection (for example, it can be adjusted to full-screen FHD display or partial high-definition and surrounding low-definition display mode), and then determine the display timing control data.

[0114] The image processing module is used to process the decoded image data, for example, it may include functions such as resolution conversion, frame rate matching, and image format conversion (for example, it can be converted into the RGB888 format required by the display device). In addition, this solution is an instruction set-based display controller with a CPU. The instruction set-based display controller can run a real-time operating system, so that the application program in the instruction set-based display controller can be used to perform more image processing, such as black and white mode, color adjustment, local high definition and other additional functions.

[0115] The timing control module is used to generate a timing according to the result processed by the image processing module and the above display timing control data. This timing is used to control the gate lines and data lines in the display panel.

[0116] The data transmission module is used to transmit display data (the display data can be display data included in the visible light wireless communication data received by the photosensitive receiver, or can be display data stored in the RAM of the display controller based on the instruction set) to the display panel.

[0117] In summary, the display device provided by the embodiments of the present application uses a visible light wireless communication controller in the display device to obtain data to be transmitted, and controls the on and off of multiple light-emitting devices in the backlight assembly based on the data to be transmitted to emit first visible light wireless communication data. This allows the transmission of visible light wireless communication data through the backlight assembly inherent in the display device, without the need to install an additional light bulb on the display device housing. This solves the problem of complex display device structures in related technologies and simplifies the display device structure. Furthermore, the display device is more aesthetically pleasing.

[0118] In addition, since the light-emitting devices in the backlight assembly can be turned on and off quickly like light bulbs in related technologies when transmitting visible light wireless communication data, and are not easily detected by the human eye, the visible light wireless communication data transmission function can be realized through the display device without affecting the user experience.

[0121] Step 902: Control multiple light-emitting devices in the backlight assembly to turn on and off based on the data to be transmitted, so as to emit first visible light wireless communication data.

[0122] In summary, the data transmission method provided in the embodiments of the present application can obtain the data to be transmitted through the visible light wireless communication controller in the display device, and control the on and off of multiple light-emitting devices in the backlight assembly based on the data to be transmitted to emit the first visible light wireless communication data. In this way, the visible light wireless communication data is transmitted through the backlight assembly inherent in the display device without installing an additional light bulb on the display device housing. This solves the problem of the relatively complex structure of the display device in the related art and achieves the effect of simplifying the structure of the display device. In addition, the display device is more aesthetically pleasing.

[0123] In addition, since the light-emitting devices in the backlight assembly can be turned on and off quickly like light bulbs in related technologies when transmitting visible light wireless communication data, and are not easily detected by the human eye, the visible light wireless communication data transmission function can be realized through the display device without affecting the user experience.
