[0002] With the development of the automotive industry and the increase in the popularity of automobiles, in-vehicle displays have become one of the key technologies for enhancing the driving experience and safety. Traditional in-vehicle display systems mainly focus on basic information display (such as vehicle speed, fuel level, water temperature), navigation services, and basic vehicle control functions. However, with the growing demand of users for in-vehicle intelligence and connectivity, these basic functions have become increasingly limited.

[0003] Currently, users hope that in-vehicle display systems can integrate more advanced functions, including but not limited to voice interaction and remote conferencing, etc., to meet the diverse travel needs of different users. To implement these functions, vehicles need to choose to additionally install a tablet computer as an auxiliary device, which can flexibly respond to user instructions and perform complex operations. As the central console of the vehicle is the core area of the in-vehicle layout and has limited space, adding a tablet computer on the basis of an already configured in-vehicle display not only occupies space resources but may also cause the driver's movements to be restricted during driving, thereby affecting driving safety.

[0004] In view of this, there is an urgent need for an in-vehicle display that can solve the above problems. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0031] In addition, the terms "first", "second", etc. in the specification and claims of the present application or in the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order, and may explicitly or implicitly include one or more of such features.

[0032] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "connected", "connected to", or "communicatively connected" should be understood in a broad sense. For example, "connected", "connected to", or "communicatively connected" can refer to not only physical connection, but also electrical connection or signal connection. For example, it can be a direct connection, that is, a physical connection, or it can be indirectly connected through at least one intermediate component, as long as the circuit is connected. It can also be the connection inside two components; signal connection can refer to signal connection through a medium in addition to signal connection through a circuit. For example, radio waves. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0033] An embodiment of the present application provides a schematic structural diagram of an in-vehicle screen, as Figure 1 shown. The in-vehicle screen includes a processing module 11, an interaction module 12, a display module 13, and a power supply module 14. The interaction module 12 is respectively connected to the processing module 11 and the display module 13, and the power supply module 14 is respectively connected to the processing module 11, the interaction module 12, and the display module 13 to supply power to the in-vehicle screen. Among them, the interaction module 12 includes an NFC unit 24, a deserialization unit 21, an audio unit 23, and a light sensing unit 22; the deserialization unit 21 is respectively connected to the processing module 11, the display module 13, the NFC unit 24, the audio unit 23, and the light sensing unit 22. The deserialization unit 21 is configured to: receive and parse the first information to be processed transmitted by the NFC unit 24, the audio unit 23, and the light sensing unit 22, and the second information to be processed transmitted by the display module 13; transmit the first information to be processed and the second information to be processed to the processing module 11, receive the processing information returned by the processing module 11, and transmit the processing information to the display module 13 for display.

[0034] The information obtained from the NFC unit 24, the audio unit 23, and the light sensor unit 22 can be defined as the first information to be processed. Since the display module 13 includes a touch control unit 132, based on the driver's click operation on the touch control unit 132, the second information to be processed is obtained. The first information to be processed and the second information to be processed are sent to the deserialization unit 21. After receiving the first information to be processed and the second information to be processed, the deserialization unit 21 parses the first information to be processed and the second information to be processed, and sends the parsed first information to be processed and the second processed signal to the processing module 11, so that the processing module 11 can receive the parsed first information to be processed and the second information to be processed. The processing module 11 then processes the received first information to be processed and the second information to be processed. After the processing module 11 processes the received first information to be processed and the second information to be processed, processed information is obtained. At this time, the processed information refers to the information obtained after the first information to be processed and the second information to be processed are processed by the processing module 11. The processing module 11 then sends the processed information to the deserialization unit 21, so that the deserialization unit 21 can transmit the processed information to the display module 13 for display. If the processed information is video information, the video information can be sent to the display module 13 for display. If the processed information is recording information, the recording information can be sent to the audio unit 23 for playback.

[0035] In a possible implementation manner, Figure 2 is a schematic structural diagram of the audio unit 23 of an in-vehicle screen provided by an embodiment of the present application. Refer to Figure 2 , the audio unit 23 includes an input subunit 232, an output subunit 234, an audio amplifier subunit 233, and a codec subunit 231; the input subunit 232 is connected to the codec subunit 231, the codec subunit 231 is connected to the audio amplifier subunit 233, the audio amplifier subunit 233 is connected to the output subunit 234, and the codec subunit 231 is connected to the deserialization unit 21; the codec subunit 231 is configured to: receive and parse the sound information transmitted by the input subunit 232; transmit the sound information to the deserialization unit 21, and receive the processed sound information returned by the deserialization unit 21, and transmit the processed sound information to the audio amplifier subunit 233 for processing.

[0036] In the audio unit 23, the codec subunit 231 refers to a Codec. The codec subunit 231 is used to parse the sound information from the input subunit 232. The input subunit 232 refers to a microphone (MIC). The MIC is one of the input devices of the audio unit 23 and is responsible for converting the sound signal into an electrical signal for subsequent encoding, processing, and transmission. After receiving the sound information, the codec subunit 231 encodes and decodes the sound information. It can convert the analog audio signal into a digital audio signal (A / D conversion) for digital processing, or convert the digital audio signal into an analog signal (D / A conversion) for use by output devices such as speakers. The codec subunit 231 is also responsible for processing audio signals, such as volume control, sound effect processing, and control of the audio path. After receiving the sound information from the input subunit 232, the codec subunit 231 then sends the sound information to the deserialization unit 21. The deserialization unit 21 is provided with a target interface, and the target interface is an I2S interface or a TDM interface. The specific interface to be selected for connection can be based on the interface adapted by the audio unit 23 to facilitate data transmission between the deserialization unit 21 and the codec subunit 231. The audio amplifier subunit 233 refers to an Audio PA. The Audio PA is a power amplification component in the audio module. Its main function is to amplify the low-power audio signal output by the Codec to drive output devices such as speakers to produce a sufficiently loud sound. The output subunit 234 refers to a speaker. The speaker is one of the output devices of the audio module. It converts the audio signal amplified by the Audio PA (audio amplifier subunit 233) into a sound signal and radiates it into the air for human ears to receive. Inside the audio unit 23, signal transmission is usually achieved through circuit boards and connection wires. Different components are connected and communicate through pins, interfaces, or buses. In addition to the audio playback function, the audio unit 23 can also be used for the driver to communicate with the controller of the remote terminal to achieve an intercom function. At this time, the remote terminal can be set based on the application scenario. If the vehicle is used by relevant department personnel, the audio unit 23 can be used to achieve a remote call with the central control processing room, and the central control processing room conducts remote dispatching based on the received information. By adding the audio unit 23, the risk of call interruption can be prevented, and the situation where the driver is distracted during driving due to the need to operate the communication device can be avoided, further improving driving safety.

[0037] In a possible implementation manner, Figure 3 is a schematic structural diagram of the NFC unit 24 of an in-vehicle screen provided by an embodiment of the present application. Refer to Figure 3, the NFC unit 24 includes an NFC chip 242 and an NFC antenna 241. The deserialization unit 21 is connected to the NFC chip 242, and the NFC chip 242 is connected to the NFC antenna 241. The NFC antenna 241 is used to receive the third information to be processed, and the NFC chip 242 is used to preprocess the third information to be processed.

[0038] NFC stands for Near Field Communication, which is a short-range high-frequency wireless communication technology. It allows electronic devices to exchange data when they are close to each other, usually within a distance of 10 centimeters. The NFC antenna 241 reads the information of the electronic device held by the user, preprocesses the read information to the NFC chip 242, and then sends the preprocessed information to the deserialization unit 21 for subsequent processing. For example, when the NFC unit 24 is applied to attendance, it is necessary to obtain the corresponding punch records of personnel when going to and from work, that is, the personnel bring the work card close to the area that can be detected by the NFC antenna 241. The NFC antenna 241 reads the work card information and sends the read work card information to the NFC chip 242, so that the NFC chip 242 can receive the work card information sent by the NFC antenna 241. At this time, the third information to be processed refers to the work card information read by the NFC antenna 241. After receiving the third information to be processed and preprocessing it, the NFC chip 242 sends the preprocessed third information to be processed to the deserialization unit 21 for processing, so that the deserialization unit 21 can send it to the processing module 11 for subsequent processing. Then, it receives the information returned by the processing module 11 and prompts the returned information in the NFC unit 24, that is, information such as successful punching or failed punching. Adding the NFC unit 24 can solve the problem of inconvenient punching for personnel going out to work, eliminating the step of personnel needing to return to the unit for punching and improving the user experience.

[0039] In a possible implementation manner, Figure 4 is a schematic structural diagram of a light sensing unit 22 of an in-vehicle screen provided by an embodiment of the present application. Refer to Figure 4 , the light sensing unit 22 includes a first light sensing subunit 221 and a second light sensing subunit 222. The first light sensing subunit 221 is used to collect the brightness of the first surface of the in-vehicle screen, and the second light sensing subunit 222 is used to collect the brightness of the second surface of the in-vehicle screen. Both the first light sensing subunit 221 and the second light sensing subunit 222 are connected to the deserialization unit 21, and the first surface and the second surface are opposite to each other.

[0040] The first photosensing sub-unit 221 and the second photosensing sub-unit 222 can be respectively arranged on the first surface and the second surface of the vehicle-mounted screen. The photosensing sub-unit refers to a photosensing device, and at this time, the photosensing device includes a brightness sensor. If the first surface is set as the front surface, where the front surface refers to the screen surface of the vehicle-mounted screen, then the second surface is set as the back surface, where the back surface refers to the surface corresponding to the rear housing of the vehicle-mounted screen, that is, the surface corresponding to the back of the vehicle-mounted screen. The brightness at different positions can be respectively sensed through the photosensing device. The first photosensing sub-unit 221 obtains the brightness of the first surface of the vehicle-mounted screen, and the second photosensing sub-unit 222 obtains the brightness of the second surface of the vehicle-mounted screen. During the driving of the vehicle, the brightness data obtained by the second photosensing sub-unit 222 can be combined with the brightness data obtained by the first photosensing sub-unit 221 and transmitted to the deserialization unit 21 for processing, so as to receive the brightness data returned by the deserialization unit 21, and then automatically adjust the brightness of the vehicle-mounted screen, reducing unnecessary accidents caused by insufficient screen brightness during driving.

The display unit is used for displaying the data transmitted after being parsed by the deserialization unit 21. When there is a touch operation by the driver, the click operation of the driver on the touch control unit 132 is received, the information to be recognized is determined, the touch control unit 132 is connected to the deserialization unit 21 using an I2C interface, and the information to be recognized is sent to the deserialization unit 21 for processing.

[0042] In a possible implementation manner, Figure 6 is a schematic structural diagram of a processing module 11 of a vehicle-mounted screen provided by an embodiment of the present application. Refer to Figure 6, the processing module 11 includes a system-on-chip 111 and a serializer 112. The system-on-chip 111 is connected to the serializer 112, the serializer 112 is connected to the deserialization unit 21, and the processing module 11 and the interaction module 12 use STP twisted pair cables for data transmission. The processing module 11 refers to the in-vehicle terminal of the vehicle-mounted screen. The interior of the processing module 11 consists of a system-on-chip 111 and a serializer 112. The system-on-chip 111 and the serializer 112 are connected using an LVDS (Low Voltage Differential Signaling) interface. The system-on-chip 111 sends data to the serializer 112 for serialization processing. The serialized data is transmitted through a physical STP twisted pair cable to the deserialization unit 21, so that the deserialization unit 21 can send it to the display module 13. The serialized data also includes audio data, and the audio data is sent to the audio unit 23 through the deserialization unit 21 for the audio unit 23 to process the audio data. Using STP twisted pair cables for transmission has the effects of reducing electromagnetic interference and noise, improving data transmission quality, and having a fast transmission speed.
