[0002] With the rapid development of smart phones and wearable devices, the resolution and refresh rate of display modules are constantly improving, which puts higher requirements on display technology. In this context, display modules with MIPI (Mobile Industry Processor Interface, MIPI for short) and DP (Display Port, DP for short) interfaces have become the mainstream choice in the market due to their high performance. In order to ensure the product quality of these high-specification display modules, they must undergo a series of rigorous tests before leaving the factory. These tests require the point screen device to have a higher transmission rate and bandwidth to meet the detection requirements of high resolution and high refresh rate.

[0003] However, the existing point-screen method has some limitations. First, the speed of the main MIPI bridge chip is limited, and it is difficult to reach a transmission rate of 2.5Gbps, or it only supports MIPIDPHY (Display Port over Mobile Industry Processor Interface D-PHY, referred to as MIPI DPHY) but not MIPI CPHY (Capture Port over Mobile Industry Processor Interface C-PHY, referred to as MIPI CPHY), which limits its scope of application. Secondly, the system structure is complex, involving multiple components such as ARM processor, FPGA (field programmable gate array) and bridge chip, which not only increases the difficulty of maintenance and troubleshooting, but also pushes up the system cost. In addition, the configuration process of the MIPI bridge chip is complicated, and the configuration standards of different manufacturers are different, which brings additional challenges to equipment maintenance and upgrades.

[0034] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0035] Embodiment 1

[0036] Reference Figure 1 As shown, the present invention provides a universal screen-pointing method, including but not limited to the following steps:

[0037] S1. PC sends screen parameters, Python scripts and control instructions;

[0038] S2, the signal board receives the point screen parameters, Python script and control instructions, executes the corresponding function in the Python script according to the control instructions, parses the point screen parameters, obtains the first parameter, and sends a completion instruction;

[0039] S3, PC receives the completion command and sends a power-on command to the signal board;

[0040] S4, the signal board executes the power-on function in the Python script according to the power-on instruction; the power-on function obtains the second parameter according to the first parameter and the preset timing parameter;

[0041] S5. The power board receives the second parameter to control the power-on timing and sends a confirmation signal. After receiving the confirmation signal, the signal board sends an interface control instruction according to the interface parameters of the display module to be detected, and sends the picture in the point screen parameters to the display module to be detected.

[0042] The embodiment of the present invention provides a universal screen-pointing method, in which a power-on function in a Python script is executed by a signal board according to a power-on instruction, and the function uses a first parameter and a preset timing parameter to calculate a second parameter. This step ensures the precise control of the power-on timing, which is beneficial to protecting the display module to be detected and ensuring the stability of the display effect. The use of Python scripts makes the embodiment of the present invention highly flexible and programmable, allowing the Python script to be adjusted according to different display modules and application scenarios to achieve customized control logic. At the same time, since the control logic is mainly implemented in the script, system maintenance and upgrades become simple, and only the script needs to be updated. This design also has good scalability and can easily adapt to more types of display modules to be detected or more complex screen-pointing processes without large-scale modifications to the existing system. Therefore, the screen-pointing method provided in the embodiment of the present invention not only improves the data transmission rate, but also enriches the interface types and optimizes the structure and configuration, effectively reducing the complexity of maintenance and troubleshooting.

[0043] Specifically, the RK3588 chip has excellent performance in display interface. It is equipped with two MIPI DSI (Display Serial Interface, DSI for short, the interface specification between processor and peripheral defined by the MIPI Alliance) controllers and two independent transmission channels. This design enables RK3588 to support up to two MIPI outputs, providing users with flexible display connection options. In terms of transmission mode, RK3588 demonstrates its compatibility and advancement. It supports both MIPIDPHY and MIPI CPHY modes. MIPI DPHY provides a guarantee for high-speed data transmission with its transmission rate of up to 4.5Gbps. MIPI CPHY, with its low power consumption and high efficiency, is suitable for occasions that require energy saving. In addition, the DP interface of RK3588 also performs well, supporting a transmission rate of up to 8.1Gbps / lane, and can achieve a refresh rate of 30Hz at 8K resolution. Such performance indicators not only meet the current market demand for high-resolution display, but also leave room for possible future advances in display technology. Therefore, the embodiment of the present invention adopts the RK3588 chip as the core processor of the signal board.

[0044] Furthermore, the main components of the signal board also include an embedded multimedia card (EMMC), a double data rate memory (DDR), and a power management chip. For the connection method of the RK3588 chip and other components, please refer to Figure 2Specifically, the RK3588 chip obtains power supply through the power management chip, connects to the DDR memory to achieve data transmission, connects to the EMMC memory to store and read data, and communicates and controls external devices through the peripheral interface.

[0045] Specifically, refer to Figure 3 In this embodiment, the PC is the host computer, which establishes a connection with the signal board through the TCP / IP or HTTP protocol. It mainly exchanges data with the network communication module in the RK3588 chip. The network communication module is responsible for receiving and sending network data, and passing these data to the thread pool processing module in the RK3588 chip. For the thread pool processing module, it manages multiple threads to improve processing efficiency and system response speed. This module contains the following four main threads:

[0046] (1) Python script processing thread: This thread is dedicated to executing Python scripts, which can contain automated tasks or specific business logic processing, providing flexibility and scalability for the system.

[0047] (2) General command processing thread: This thread is responsible for processing regular commands, which may come from user input through the interface or requests from other modules within the system, ensuring that user instructions and internal system communications are responded to in a timely manner.

[0048] (3) Non-business command processing thread: This thread is used to process commands that are not related to business logic, such as system configuration, status query, or other system-level operations, to ensure system stability and maintainability.

[0049] (4) Internal module communication thread: This thread is responsible for coordinating the communication between modules within the system, ensuring that data and commands are transmitted correctly between modules and maintaining the overall coordination and consistency of the system.

[0050] The data and commands processed by the above thread pool processing module will eventually be sent to the underlying driver module. The underlying driver module is built into the RK3588 chip and is a bridge for the interaction between the system and the hardware. It is responsible for converting software-level commands into signals that the hardware can understand, thereby controlling the hardware device to perform the corresponding operations. In addition, the underlying driver module provides a rich variety of interface types to adapt to different hardware devices and communication requirements. These interfaces include the Serial Peripheral Interface (SPI), which is a high-speed, full-duplex, synchronous communication bus commonly used for communication between microcontrollers and peripheral devices. At the same time, it also supports the USB (Universal Serial Bus) interface, which is a widely used interface for connecting various external devices such as storage devices, input devices, etc. Through these interfaces, the underlying driver module can flexibly interact with various hardware devices, ensuring the scalability and compatibility of the system. This design not only improves the stability and reliability of the system, but also facilitates the future development and upgrade of the system.

[0051] In order to fully and clearly demonstrate the method described in the present invention, the specific steps of the universal screen-pointing method provided by the present invention are as follows:

[0052] Step 1: Send parameters and scripts. The host computer prepares all the parameters required for screen point display, including screen specifications, timing requirements, voltage settings, etc., as well as the required image files and Python scripts for controlling the screen point display process. The host computer packages these parameters, images, and Python scripts through a predefined communication protocol and sends them to the signal board. These parameters and scripts are packaged and sent to the signal board through a predefined communication protocol, laying the foundation for the automation and accuracy of the screen point display process.

[0053] Step 2: Initialization script execution. The host computer sends an initialization command to the signal board. After receiving the command, the signal board starts the Python script processing thread. The initialization function in the Python script is executed, which is responsible for parsing all parameters sent by the host computer. According to the parsed voltage parameters, the Python script calls the underlying driver through the internal communication thread, communicates with the FPGA through the SPI or USB interface, and transmits the voltage setting parameters.

[0054] Step 3: Power-on process control. After the host computer completes initialization, it sends a power-on command to the signal board, and the signal board executes the power-on function in the Python script. The power-on function communicates with the FPGA to control the power-on timing according to the previously parsed parameters and timing requirements. At the same time, according to the screen interface parameters, the display interface is controlled through the internal module communication thread and the underlying driver, and the control command is sent to the display module. The image content is loaded into the video memory so that the required image can be correctly displayed on the display module.

[0055] Step 4: Subsequent command processing. After power-on is completed, the host computer can send other commands, such as OTP (one-time programming) process, etc. The universal point screen method based on RK3588 integrates various processes and control parameters into Python scripts to meet the needs of complex processes. This method reduces the frequency of program updates and improves the flexibility and maintainability of the system.

[0056] Step 5: Error handling and logging. Integrate error handling mechanisms in Python scripts to ensure that clear error messages are given and appropriate recovery measures are taken when communication fails or parameter errors occur. The script should record detailed operation logs to facilitate troubleshooting and performance monitoring.

[0057] Through the above steps 1 to 5, the universal screen point method provided by the embodiment of the present invention not only improves the overall detection speed, but also achieves compatibility with the DPHY and CPHY interfaces of MIPIDSI, thereby achieving remarkable results in reducing costs and power consumption.

[0058] Furthermore, the built-in video hard decoding function of the RK3588 chip gives the dot-screen device powerful video playback capabilities, which gives it a clear advantage when competing with dot-screen devices that can only display static images.

[0059] Specifically, the display subsystem of the RK3588 chip consists of multiple key components and interfaces to realize the processing and output of video signals. Figure 4As shown. The core of the system is the Central Processing Unit (CPU), which is responsible for executing program instructions and processing data. Working in conjunction with the CPU are the Graphics Processing Unit (GPU), Resizer and Graphics Accelerator (RGA) and Video Processing Unit (VPU), which are responsible for advanced processing tasks of graphics and video respectively. The double data rate memory in the figure serves as the main storage medium, providing the CPU and other components with necessary data and program storage. These components are interconnected through a bus (BUS) to ensure that data and instructions can be transmitted quickly. The Video Output Port (VOP) is the last stop in video signal processing, which distributes the processed signal to different output channels, namely VP0, VP1 and VP2. These output channels are connected to various display interfaces through connectors, including High-Definition Multimedia Interface (HDMI), Embedded DisplayPort or DisplayPort (eDP / DP), Mobile Industry Processor Interface-Display Serial Interface (MIPI DSI), and interfaces that support RGB, BT1120 and 656 standards. These interfaces enable the system to be connected to a variety of display devices, such as TVs and display panels. In addition, the system also supports Low Voltage Differential Signaling (LVDS), which is a technology for high-speed data transmission, particularly suitable for connecting displays. The entire system is designed to efficiently process video signals and output them to various display devices to meet the needs of different users. Therefore, the point screen device manufactured by the general point screen method based on the RK3588 chip design in this embodiment has a video playback function.

[0060] Embodiment 2

[0061] Based on the same inventive concept, this embodiment provides a universal screen dot device based on the RK3588 chip, and its principle of solving the problem is similar to the universal screen dot method based on the RK3588 chip provided in Example 1, and the repeated parts will not be repeated.

[0062] Reference Figure 5 As shown, this embodiment provides a universal point screen device based on the RK3588 chip, including:

[0063] PC, used to send screen parameters, Python scripts and control instructions;

[0064] The signal board is connected to the PC; the signal board includes an RK3588 chip, which is used to execute the corresponding function in the Python script, parse the point screen parameters, obtain the first parameter, and send a completion instruction;

[0065] The power board, including the FPGA chip, is connected to the RK3588 chip;

[0066] Crimp the transfer board to connect with the power board and signal board.

[0067] In this embodiment, the universal point screen device provided is centered on its signal board, which integrates a high-performance RK3588 chip. This chip is specifically responsible for processing signals received from the PC end, ensuring the accuracy and real-time nature of the signal. The PC communicates with other components in the system through the signal board, sending necessary control instructions and data to achieve precise control of the displayed content. As the energy supply center of the device, the power board has a built-in FPGA, which enables the power board to not only manage power but also perform complex signal conversion tasks. By crimping the transfer board, the power board and the signal board achieve a stable and reliable connection. This design ensures the continuous transmission of power and signals, providing a basis for the stable operation of the system.

[0068] Specifically, the crimping transfer board integrates a variety of key signals, including multi-channel voltages, MIPI (Mobile Industry Processor Interface) and DP and other point screen signals, which are essential for the high-performance operation of the display module. Among them, the multi-channel voltages are stored in the multi-channel voltage storage unit of the crimping transfer board. In addition, the signal storage unit in the crimping transfer board also supports control signals such as GPIO (general purpose input and output), I2C (integrated circuit bus), SPI (serial peripheral interface), etc. These signals act together on the display module to be tested, ensuring that the display module to be tested can receive and correctly process the instructions from the signal board.

[0069] Specifically, the display module to be tested is the final output part of the device. It is connected to the power board and signal board through wires to form a complete signal and power transmission link. This design not only realizes the effective transmission of power and data, but also ensures that the display module to be tested can present images and video content with high quality.

[0070] The above design focuses on achieving efficient signal processing and stable power supply, the combination of which provides a solid foundation for high-quality display output. Through this modular and flexible design, the universal point screen device of this embodiment can adapt to diverse display needs and application scenarios, and can provide excellent performance and reliability whether in commercial display, education or home entertainment.

[0071] In actual application scenarios, display module manufacturers must conduct detailed tests on their products during the quality control process to ensure that each display module can meet the established performance standards. The universal point screen device provided by the embodiment of the present invention, relying on the powerful processing capability of the RK3588 chip, provides a set of accurate and efficient solutions for the testing of display modules. The following are the specific working steps of the device in actual application:

[0072] First, the signal board communicates with the PC: The main task of the signal board is to establish a connection with the PC, receive and parse the key parameters required for display module testing. These parameters include voltage, data and control signals, which are transmitted to the RK3588 chip to generate specific data and voltage that meet the display module test specifications. Among them, the PC, as the control center, is responsible for sending instructions and parameters to the signal board to ensure the accurate execution of the test process.

[0073] Secondly, the control function of the power board: the power board has a built-in FPGA chip that communicates with RK3588 to achieve precise control of power timing and voltage. This step is crucial for simulating the power requirements of the display module under actual working conditions.

[0074] Finally, the signal and power transmission: the power signal provided by the power board and the point screen signal data and control signal generated by the signal board are introduced through the crimping adapter and finally connected to the display module through the wire. This step ensures that the display module can receive the correct voltage and data signal for subsequent testing and display.

[0075] This embodiment uses the communication between the signal board and the PC as a starting point to achieve accurate reception and analysis of key parameters required for display module testing, including voltage, data and control signals, which are transmitted to the RK3588 chip to generate specific data and voltage that meet the test specifications. Such an integrated method not only improves the accuracy and efficiency of the test, but also enhances the automation of the test process. The communication between the FPGA chip built into the power board and the RK3588 further ensures the precise control of the power timing and voltage size, which is crucial for simulating the power requirements of the display module under actual working conditions, thereby improving the reliability of the test. Finally, the power signal and the point screen signal data and control signal generated by the signal board are introduced through the crimping transfer plate and connected to the display module, ensuring that the display module can receive the correct voltage and data signals for subsequent testing and display. This design brings multiple benefits such as precise control, efficient testing, power management, system integration, flexibility, stability, scalability, easy maintenance, cost-effectiveness, and data and power integration, improving the overall performance and reliability of the display module test while reducing costs and maintenance difficulties.
