In addition, the order of the operations can be rearranged. The process can be terminated when its operations are completed, but it can also have additional steps not included in the figures. The process can correspond to a method, function, procedure, subroutine, subprogram, etc.

However, the present invention can be embodied in many alternative forms and should not be construed as limited only to the embodiments set forth herein.

[0031] However, in the prior art, in order to achieve the interactive communication between the screen and the host, it is often necessary to design a variety of I / O interfaces and channels according to the interactive control content, and the wire harness between the screen and the host needs to meet very strict shielding requirements. Otherwise, signal distortion will occur due to interference, resulting in phenomena such as screen flashing and freezing. It is difficult to ensure the communication efficiency and data reliability between the screen and the host, seriously reducing the user experience.

[0032] The technical solution of the present invention provides a communication method between a control assembly and a display assembly. Different from the prior art, the channel path is simplified, that is, only a shielded wire path for high-speed data stream transmission is configured at the high-speed data transmission interfaces correspondingly provided in the control assembly and the display assembly, effectively avoiding electromagnetic interference between multiple channel paths. To ensure high-reliability signal transmission, the data stream is framed and parsed by the control assembly and the display assembly respectively in sequence, so as to convert the serial transmission and parallel transmission of the data stream as needed.

[0033] The communication device, computer storage medium and vehicle provided by the technical solution of the present invention are used to solve the problems in the prior art that signal distortion is caused by mutual interference of multiple wire harnesses between the screen and the host, and it is difficult to ensure communication efficiency and data reliability.

[0034] To specifically describe how the technical solution of the present invention solves the defects existing in the prior art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Embodiment 1:

[0036] Reference Figure 1 , which discloses the communication method between the control assembly and the display assembly of Embodiment 1 of the present invention. The control assembly includes a system chip and a serializer, and the display assembly includes a display screen, a deserializer and a microcontroller. High-speed data transmission interfaces are correspondingly provided in the control assembly and the display assembly, and only a shielded wire path for realizing high-speed data transmission between the control assembly and the display assembly is configured between the two interfaces. The control assembly frames and encodes the data stream to be sent through the serializer, and the shielded wire path transmits the encoded data frame to the display assembly at high speed. The display assembly receives the encoded data frame and parses the data frame through the decoder, and sends the imaging signal obtained after parsing to the display screen. The communication method of this embodiment converts multiple low-speed parallel signals into high-speed serial signals through the serializer provided in the control assembly. The high-speed serial signal is transmitted to the display assembly through the only shielded wire path configured by the high-speed data transmission interface, and the high-speed serial signal is reconverted into low-speed parallel signals through the deserializer provided in the display assembly. It can make full use of the channel capacity of the transmission medium, reduce the required number of transmission lines and device pins, greatly reduce the communication cost, and improve the data transmission efficiency. At the same time, it avoids signal distortion caused by electromagnetic interference between multiple channels, which is conducive to obtaining a low-cost, high-efficiency and high-reliability communication method between the control assembly and the display assembly.

[0037] Low Voltage Differential Signaling (LVDS) transmission technology is a small-amplitude differential signaling technology that reduces the supply voltage and logic voltage swing. It can overcome the problems of high power consumption, latency, and distortion that were prone to occur in early parallel buses, and has characteristics such as high communication rate, small time offset, low noise, and low power consumption. In this embodiment, the high-speed data transmission interface is configured as a low-voltage differential signal interface, including a first low-voltage differential signal interface correspondingly set on the control assembly and a second low-voltage differential signal interface set on the display assembly.

[0038] In this embodiment, the imaging signals include video image signals, backlight enable signals, and backlight control signals. Different from the prior art where image signals, backlight enable signals, and backlight control signals are often transmitted between the control assembly and the display assembly through multiple data transmission channels, in this embodiment, the control assembly first frames and encodes the data stream to be transmitted through a serializer. The imaging signals are framed and encoded into serial signals within the control assembly and then transmitted at high speed to the display assembly through a shielded wire path as encoded data frames, with a maximum support for a high speed of 400KHz and an actual maximum effective rate of approximately 370kHz. The display assembly receives the encoded data frames and parses the data frames through a decoder. The video image signals, backlight enable signals, and backlight control signals obtained after parsing the data frames are sent in parallel to the display screen for display. Among them, the BacklightEnable Signal is used to control the closing and opening of the backlight switch, and the Backlight ControlSignal can control the backlight brightness by changing the PWM duty cycle.

[0039] As Figure 1 shown, in this embodiment, the control assembly and the display assembly are correspondingly provided with adapted high-speed data transmission interfaces. This high-speed data transmission interface can support high-speed data transmission between the control assembly and the display assembly and power supply from the control assembly to the display assembly at the same time. In addition, it can also expand the power supply protocol as needed to implement power supply schemes such as continuous, intermittent, wired, or wireless methods.

[0040] Embodiment 2:

[0041] With the development of touch technology, users can apply their operation intentions to the machine through touch operations on the touch screen, improving the efficiency of human-machine interaction and the degree of intelligence. The user's human-machine interaction experience is even more based on a stable and reliable interaction communication foundation.

[0042] Based on the communication method provided in Embodiment 1, this embodiment provides a communication method between the control assembly and the display assembly in a human-machine interaction occurrence scenario. In this embodiment, as Figure 2 、 Figure 3As shown, the microcontroller of the display assembly is configured to monitor touch operations on the display screen in real time. When a touch operation occurs, the microcontroller acquires touch operation data related to the touch operation, stores the touch operation data in a register, and sends an interrupt request signal to the control assembly. After receiving the interrupt request signal, the control assembly reads the touch operation data of the display assembly. During this process, the control assembly is the Master side and the display assembly is the Slave side. Only when the control assembly receives the interrupt request signal sent by the display assembly can it actively read the touch operation data stored in the display assembly, and according to the mapping relationship between the touch operation data and the imaging signal, output the corresponding imaging signal and perform framing and encoding on the imaging signal through a serializer.

[0043] To facilitate the system to clearly distinguish how many touches occur on the display screen currently and provide function reservation for the subsequent possible multi-touch function of the touch screen, the control assembly frames and encodes the coordinate position information acquired by the microcontroller, and configures it into the form of a standard frame or a standard frame + a preset-length extended frame according to the number of touch points. Specifically, the microcontroller real-time detects and acquires the coordinate position information corresponding to the touch operation on the screen (the coordinate takes the upper left corner of the display area of the touch screen as the origin, the horizontal right is the positive direction of the X axis, and the vertical down is the positive direction of the Y axis; the reported point coordinates correspond to the physical pixel points of the touch screen), and stores the above data in a register. The control assembly reads the data in the register and frames and encodes the coordinate position information according to the number of touch points. When the number of touch points is less than or equal to 2, the position information of the touch points is configured into a standard frame. When the number of touch points is more than 2, the position information of the touch points is configured into the form of a standard frame + a preset-length extended frame.

[0044] Furthermore, the data frame is configured with an extended frame length check part and a sum check part. If more than two touches are transmitted, the number of bytes indicating the extended frame length of the remaining touch points is noted. The I2C Master reads the remaining extended touch data in the next frame without waiting for an interrupt. And before the end of the reading process, the extended frame length check and the sum check of the entire data frame will be performed on the data. If an extended frame length check and / or a sum check error occurs in the data read by the control assembly, the same reading operation will be performed again within the same interrupt request cycle, so as to double-guarantee the validity of the extended frame through the extended frame length check and the sum check method, and improve the accuracy and correctness of data transmission.

[0045] In addition, the data frame is also configured with an acknowledgement section. When the control assembly reads the touch data, after the control assembly sends a read command to the display assembly, the display assembly sends the data to the control assembly in accordance with the data frame format. The control assembly sends a confirmation acknowledgement frame every time it receives the coordinate position information of a touch point. Through the process of data interaction between the control assembly and the display assembly, the accuracy and correctness of data transmission are further ensured.

The control assembly and the display assembly are respectively provided with a serializer for data stream framing and a deserializer for data frame parsing. The control assembly and the display assembly are connected through a corresponding high-speed data transmission interface. The high-speed data transmission interface is only configured with a shielded wire path to achieve high-speed data transmission between the control assembly and the display assembly.

[0048] To further enhance the human-computer interaction function of the communication device, the communication device further includes:

[0050] An interrupt processing module configured to receive the interrupt request signal sent by the display assembly, read the touch operation data cached in the display assembly, and output corresponding imaging signals according to the mapping relationship between the touch operation data and the imaging signals, and frame and encode the imaging signals through the serializer;

[0051] A touch processing module configured to, after obtaining the touch operation data of the user acting on the display screen, send an interrupt request signal to the interrupt processing module, and at the same time store the touch operation data in a register in the microcontroller.

[0052] Embodiment 4:

[0053] Based on Embodiment 1, the technical solution of the present invention provides a computer storage medium. A computer program is stored on the computer-readable storage medium. When the computer program is executed, a communication method between the control assembly and the display assembly is implemented.

[0054] The communication method between the control assembly and the display assembly configures a shielded wire path for high-speed data stream transmission through a high-speed data transmission interface correspondingly set between the control assembly and the display assembly. The control assembly and the display assembly respectively frame and parse the data stream successively. Specifically, the control assembly includes a system chip and a serializer, and the display assembly includes a display screen, a deserializer, and a microcontroller. The control assembly and the display assembly are correspondingly provided with high-speed data transmission interfaces, and only a shielded wire path for realizing high-speed data transmission between the control assembly and the display assembly is configured between the two interfaces. The control assembly realizes framing and encoding of the data stream to be sent through the serializer, and the shielded wire path transmits the encoded data frame to the display assembly at high speed. The display assembly receives the encoded data frame and parses the data frame through the decoder, and sends the video image signal, backlight enable signal, and backlight control signal obtained after parsing to the display screen.

[0055] In this embodiment, the imaging signal includes a video image signal, a backlight enable signal, and a backlight control signal. Different from the prior art where the image signal, backlight enable signal, and backlight control signal are often transmitted between the control assembly and the display assembly through multiple data transmission channels, in this embodiment, the control assembly first realizes framing and encoding of the data stream to be sent through the serializer. The imaging signal is framed and encoded into a serial signal in the control assembly, and the encoded data frame is transmitted to the display assembly at high speed through the shielded wire path. The display assembly receives the encoded data frame and parses the data frame through the decoder. The video image signal, backlight enable signal, and backlight control signal obtained after parsing the data frame are sent to the display screen in parallel for display. Among them, the backlight enable signal (Backlight Enable Signal) is used to control the closing and opening of the backlight switch, and the backlight control signal (Backlight Control Signal) can control the backlight brightness by changing the PWM duty cycle.

[0056] As Figure 1 shown, the control assembly and the display assembly in this embodiment are correspondingly provided with adapted high-speed data transmission interfaces. This high-speed data transmission interface can support high-speed data transmission between the control assembly and the display assembly and power supply from the control assembly to the display assembly at the same time. In addition, it can also expand the power supply protocol according to needs to realize power supply schemes such as continuous, intermittent, wired or wireless methods.

[0057] The microcontroller monitors and obtains the touch operations on the display screen in real time, stores the touch operation data, and sends an interrupt request signal to the control assembly. The control assembly receives the interrupt request signal and actively reads the touch operation data of the display assembly. According to the touch operation data, the imaging signal is changed and framed and encoded through the serializer.

[0058] To facilitate the system to clearly distinguish the current touch operation on the display screen as a multi-point touch and to provide functional reservation for the subsequent possible multi-point touch operation functions of the touch screen, the control assembly frames and encodes the coordinate position information obtained by the microcontroller, and configures it into the form of a standard frame or a standard frame + an extended frame with a preset length according to the number of touch points. Specifically, the microcontroller real-time detects and obtains the coordinate position information corresponding to the touch operation on the screen, stores the above data in the register, the control assembly reads the data in the register and frames and encodes the coordinate position information according to the number of touch points. When the number of touch points is less than or equal to 2, the position information of the touch points is configured into a standard frame. When the number of touch points is more than 2, the position information of the touch points is configured into the form of a standard frame + an extended frame with a preset length.

[0059] To ensure the accuracy and correctness of data transmission, the data frame is configured with an extended frame length check part and a sum check part. If an extended frame length check and / or sum check error occurs in the data read by the control assembly, within the same interrupt request cycle, the same read operation is performed again.

[0060] In addition, the data frame is also configured with an acknowledgment part. When the control assembly reads the touch control data, after the control assembly sends a read command to the display assembly, the display assembly sends the data to the control assembly according to the data frame format. The control assembly sends a confirmation acknowledgment frame every time it receives the coordinate position information of a touch point. Through the data interaction process between the control assembly and the display assembly, the accuracy and correctness of data transmission are further ensured.
