[0002] With the development of microdisplay technology, microdisplays are widely used in fields such as virtual reality, augmented reality, portable devices and military equipment. Traditional microdisplays usually use LCD (liquid crystal display) or LED (light-emitting diode) technology, but these technologies have certain limitations in terms of brightness, power consumption, contrast and response time. For example, LCD displays rely on backlight sources, resulting in low contrast and high power consumption; while LED displays have higher brightness and contrast, but are still not ideal in terms of response time and power consumption.

[0003] In recent years, silicon-based OLED (organic light-emitting diode) display technology has gradually become a research hotspot and application direction in the field of micro-displays due to its advantages such as self-luminescence, high contrast, wide viewing angle, fast response time and low power consumption. Silicon-based OLED displays can emit light directly without backlight, greatly reducing power consumption and providing better display effects. However, the existing silicon-based OLED display detection and control technology is still imperfect, especially in terms of efficient and accurate control and detection methods.

[0004] Currently, there is a lack of image generators (PGs) on the market that can efficiently control silicon-based OLED microdisplays. Especially when performing complex operations such as image display, brightness adjustment, timing control, and aging testing, existing solutions are difficult to meet users' needs for display effects and detection accuracy. In addition, existing detection systems often do not have flexible communication methods and stable power management modules, and cannot provide a stable and reliable detection environment. Therefore, there is an urgent need for a detection system that integrates video signal control, stable power management, and multi-protocol communication to achieve efficient detection and control of microdisplays, thereby overcoming the limitations of existing technologies. Summary of the invention

[0005] One object of the present application is to provide a microdisplay detection system, method, device and medium, at least to solve the technical problems of microdisplay detection.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] First embodiment

[0030] The first embodiment of the present application relates to a micro display detection system. Figure 1 As shown, the system may include:

[0031] The video signal image generation (PG) module is used to generate a video signal and transmit it to the micro display. This module can generate image signals of different resolutions, grayscale levels and colors through a preset image processing algorithm to adapt to different types of micro displays. The generated image signal is transmitted to the micro display through the control interface module for display to ensure the display effect and quality of the image.

[0032] The host computer module communicates with the video signal generating module through the MQTT protocol to control the operation of the video signal generating module. The interface of the host computer module allows the user to set parameters such as the dot screen configuration, initialization code and timing file of the display. The user can monitor the operating status of the video signal generating module through this module and adjust the configuration according to actual needs. Through the MQTT protocol, the host computer module can quickly and efficiently transmit control instructions to ensure timely system response.

[0033] A control interface module is used to connect the video signal source and the video signal generating module, as well as the video signal generating module and the micro display, to coordinate the transmission and processing of the video signal. The module supports IIC and MIPI communication protocols, and can automatically switch the communication mode according to the requirements of different displays to ensure the accurate transmission and processing of the video signal. The control interface module can also coordinate the transmission order and format conversion of the video signal, so that the video signal can be transmitted to the micro display in the optimal form.

[0034] The power management module is used to provide and manage system power. The module can monitor the voltage and current of each channel in real time and perform power management according to the set upper and lower limits. If it is detected that the voltage or current exceeds the set range, the power management module will automatically power off to protect the device. In addition, the power management module supports power timing control to ensure that the power supply and switching sequence of the system in different working modes are reasonable.

[0035] When in use, the user first inputs the relevant configuration parameters through the host computer module, and downloads these configurations to the video signal image generation module through the MQTT protocol. Then, the control interface module is responsible for receiving the signal from the video signal source and transmitting it to the video signal image generation module for processing. The processed signal is transmitted to the micro display through the control interface module for display. The power management module monitors the power status of the system in real time during the whole process to ensure the safe and stable operation of the system. The user can also view the working status of the micro display in real time through the host computer module, and adjust the relevant configuration according to the detection results to optimize the display effect.

[0036] It is not difficult to find that compared with the related technology, the solution provided in the embodiment of the present application realizes efficient and accurate detection and control of the micro display, has the advantages of high communication efficiency, flexible operation, safety and stability, and is suitable for various types of micro display detection scenarios.

[0037] Second embodiment

[0038] The second embodiment of the present application relates to a micro display detection system. The second embodiment is an improvement on the first embodiment, and the specific improvements are:

[0039] like Figure 2 As shown, the video signal image generator (i.e., the video signal image generating module) includes a power interface, an RGB interface, a MIPI interface, and an HDMI interface, through which the point-to-screen, control, and monitoring operations of the micro display are realized.

[0040] Power interface (POWER-OUT): The power interface provides stable output and has voltage and current monitoring functions. The host computer software can monitor the power supply in real time and automatically cut off the power to protect the equipment.

[0041] RGB interface: connect the RGB dot screen channel of the micro display through this interface to realize dot screen operation. Users can control PG to generate RGB format image signals through the host computer module and pass them to the display for display.

[0042] MIPI interface: MIPI interface is used to connect micro displays that support MIPI protocol and is responsible for high-speed transmission of video signals. Through this interface, the display can be controlled in timing and the screen can be switched to ensure synchronization and stability of the display effect.

[0043] HDMI interface: HDMI interface is used to transmit high-definition digital video signals. It can input the signal of external video source into PG, and then transmit it to micro display for display through control interface module. This interface supports multiple resolutions and image formats to meet different display requirements.

[0044] The video signal image generator includes timing management function, image switching and screen control function, life test function and monitoring function. The video signal image generator can control the working timing of the micro display by writing, modifying and deleting the timing file. The user can edit the timing file through the host computer module and download it to the PG to ensure that the display is displayed and operated according to the predetermined timing.

[0045] The video signal image generator supports image switching operations. Users can switch between different display modes through the host computer module and select the appropriate image signal to output to the micro display to meet the test requirements of different scenarios.

[0046] The system also has a micro display life test function. Users can set the test plan of continuous display and different brightness changes through the host computer module. The PG will automatically perform the life test and record the display's current, voltage and other data through sensors to help users analyze the performance and durability of the display.

[0047] PG is equipped with current and voltage sensors, which can monitor the working current and voltage of the micro display in real time and transmit the data to the host computer module for display. Users can adjust the power supply parameters or debug the display according to the monitoring data to ensure the stable operation of the system.

[0048] When in use, the user sets various parameters of PG through the host computer software interface, such as selecting RGB or MIPI interface, and adjusting the dot screen configuration and timing file according to the needs of the display. After the configuration is completed, the video signal image generator will generate the corresponding video signal and transmit it to the micro display. At the same time, the system monitors the current and voltage in real time and records the life test data. The user can adjust the system settings at any time through the host computer module to optimize the display effect.

[0049] like Figure 3As shown, in order to meet the needs of users and improve user satisfaction, each window of the host computer module uses third-party controls. You can choose to view the various functions of the software from the left. In the main interface, you can use the control to select the IP address of the PG to be connected to communicate with the PG's lower computer through MQTT communication.

[0050] The host computer module interface includes a screen window for manual operation or script running, and real-time monitoring of the voltage and current conditions of each channel. Users can perform manual operations or run preset scripts through this window. Manual operation includes directly controlling the operating status of the micro display through the user interface, while script running can achieve batch or automatic operation. This function is particularly suitable for use in the initialization and daily operation test of the micro display. In the screen window, the host computer provides real-time monitoring of the voltage and current conditions of each channel.

[0051] Select the previously saved point screen configuration and initialization code, and click Download Configuration to import it into PG through MQTT. Figure 4 As shown, after downloading the configuration, you can turn on the screen. You can transmit signals through RGB. After clicking the screen, you can modify the displayed image through the buttons in the middle. This function is realized by sending instructions to control the pictures saved in PG in advance. After lighting the screen, you can monitor the voltage and current values ​​of each pin used by the current screen through the voltage and current monitoring control on the left to understand the current status of the display.

[0052] like Figure 5 As shown, click the manual operation in the upper left corner to enter the PG manual interface, where users can set the voltage of each pin, including VDD, VCC10, OTP, VSP, VSN, VSP2 and other voltage channels, and can monitor the voltage and current of these channels in real time. Through the "Set" button, users can directly adjust the target voltage to achieve precise power management.

[0053] The interface also provides the function of adjusting the current magnification. Users can switch the current magnification according to different detection requirements, and use it to detect large and small currents in different states. This can meet the testing requirements of the micro display in different working modes and ensure the normal operation of the system under various current conditions.

[0054] In the voltage and current setting interface, the system sets the maximum and minimum values ​​of voltage and current to ensure that the system can still operate safely under extreme conditions. When it is detected that the current or voltage exceeds the set range, the system will automatically issue a warning message to prompt the user to check and adjust.

[0055] The channel operation window is used to perform system control operations related to the PG. Users can use this window to restart the PG, restart the PG application, and perform LED flashing tests. This window also allows users to adjust the RGB information and grayscale level of the PG output display to test the display effect of the micro display in different colors and grayscales.

[0056] The picture switching display window allows users to select the pictures to be displayed on the micro display and switch them. This function supports multiple picture formats and can display the pictures selected by users in real time, making it convenient for users to test the display effects of different images on the display. In addition, it also supports operations such as image rotation and flipping to meet different display requirements.

[0057] Screen control window, through which users can turn on or off the screen, select the corresponding PG device, configure the screen and load the initialization code, download the configuration file and update the timing settings. This function provides a flexible and convenient control method for the initial setting and subsequent testing of the micro display.

[0058] Register operation window, users can read and write PG registers through this window. This function can be used to adjust the internal parameters of PG to optimize the working state of the micro display or perform specific functional tests.

[0059] In the video playback window, users can select and play video files to test the video playback function of the micro display. By selecting the video path, users can import the test video into the system and use the playback function to view the video playback effect on the micro display in real time. This function is suitable for comprehensive evaluation of the dynamic picture performance of the micro display.

[0060] like Figure 6As shown in the figure, configure the point screen parameters in the host computer module. First, fill in the configuration name at 1, click Save at 2, and a new configuration can be generated at 3. This interface currently displays the drive signal. After modifying the parameters on the right, click Compile Timing to generate a new timing file and save it to the file directory. When this configuration is selected, click Update TIMMING to download this timing to PG. More PG parameters can be viewed at the position indicated by 4. Users can set parameters related to the drive signal in the parameter adjustment area on the right, such as MIPI LINES, horizontal / vertical synchronization signals, etc. After the adjustment is completed, the user clicks the "Compile Timing" button, and the system will generate a new timing file based on the modified parameters and save it to the file directory. When a new configuration needs to be applied, the user can select the corresponding configuration and click the "Update TIMMING" button. The system will download the new timing file to PG through the communication interface, complete the timing update of PG, and enable the new drive signal and display parameters to act on the micro display.

[0061] like Figure 7 As shown in the figure, users can set the power-on voltage of each channel through the host computer module, and can set the upper and lower limits of voltage and current. The system will monitor the voltage and current of each channel in real time. When it is detected that the voltage or current exceeds the set upper and lower limits, the PG device will automatically perform a forced power-off operation to protect the safety of the device and the display.

[0062] like Figure 8 As shown in the figure, in the power sequence interface, users can set the power-on and power-off time sequence for each channel and its pins. For example, users can accurately adjust the time interval between power-on or power-off of each power supply to ensure that the micro display is safely started or shut down in the preset sequence, avoiding system failures caused by incorrect power-on sequence.

[0063] like Fig. 9 As shown in the figure, this module allows users to configure the register values ​​required to light up the screen. In this interface, users can choose different register writing methods, such as: MIPI format to IIC writing, IIC format direct writing and MIPI format direct writing. In addition, users can also choose the communication method from PG to the screen according to specific needs, including IIC and MIPI communication modes. For IIC mode, users need to set parameters such as line number, address, data format, read and write delay, and can also configure the corresponding voltage value for the communication channel to ensure the stability and accuracy of communication.

[0064] like Fig.10As shown in the figure, the interface allows the user to select the image to be displayed from the graphics library and add the selected image to the image list below. When the corresponding configuration is loaded, the user can load the image to the micro display through the PG for display. During this process, the user can preview and switch the display content through the host computer to ensure accurate presentation of the image.

[0065] like Fig.11 As shown in the figure, this function supports the configuration and monitoring of aging test. In the aging test interface, users can set the aging test rhythm. During the test, the system will monitor and record the changes in register values ​​in real time. Through this function, users can detect the stability and performance of the micro display under long-term working conditions to ensure that the device meets the design life requirements.

[0066] like Fig.12 As shown in the figure, the device management module allows users to manage the connected PG devices. Users can replace the lower-level screen program and screen timing of the connected PG, and support simultaneous connection of multiple PG devices. This function facilitates users to achieve efficient management and control of multiple devices in complex test or production environments.

[0067] like Fig.13 As shown in the figure, the software setting interface is used to manage the connection with the server. Users can set the server address and connection parameters in this interface to ensure smooth communication between the host computer module and the remote server. In addition, users can also configure related software parameters to meet actual usage requirements.

[0068] Through the power management module, users can accurately set the power-on voltage of each channel and monitor the actual voltage and current values. Once the voltage or current is detected to exceed the preset upper and lower limits, the system will automatically force power off to prevent equipment damage caused by power anomalies. Compared with the traditional manual monitoring of power status, this system improves the automation of power management and ensures the safety and stability of equipment operation.

[0069] By setting the power-on and power-off sequence of each channel and pin, this system allows users to accurately adjust the power-on sequence of different devices, thereby avoiding abnormal operation or damage of the device due to incorrect power-on sequence. Especially in complex devices with multiple channels and multiple pins, accurate control of the power-on sequence is crucial to the stable operation of the device. Compared with the manual adjustment of the power-on sequence, this system greatly improves the flexibility and accuracy of the timing configuration.

[0070] This system supports multiple communication methods, including common communication protocols such as MIPI and IIC. Users can choose the corresponding communication method according to the needs of different devices. In addition, this system also provides a variety of register write modes, which is convenient for users to flexibly choose in different scenarios and improve the compatibility and adaptability of the system. Especially for the driving requirements of different screen types, this system makes the initialization of the screen more efficient and convenient through customizable register value configuration.

[0071] Users can select images through the host computer interface and load them into the display for real-time preview and switching. Compared with the traditional method of changing the display content by hardware operation, this system provides a more intuitive and convenient operation interface, allowing users to easily switch the display of images, saving operation time and improving operation efficiency.

[0072] The aging test supports real-time monitoring of the beat setting and register values, and can detect the performance changes of the microdisplay during long-term operation. By recording and monitoring the register values ​​in real time, users can discover possible hardware failures or performance degradation in advance to ensure that the device meets the expected life requirements. Compared with traditional manual aging tests, this system provides a more accurate and traceable test process, greatly improving the test reliability of the equipment.

[0073] Supports simultaneous connection and management of multiple PG devices. Users can centrally control and operate multiple PG devices on the host computer interface, simplifying the difficulty of device management during large-scale testing or production. Through the device management module, users can simultaneously replace the lower-machine point screen programs and timing files of multiple PGs, thereby improving the efficiency of production testing and the convenience of equipment operation and maintenance.

[0074] Through software settings, flexible connection with remote servers is achieved, supporting users to customize server parameters and ensure that the host computer module can exchange real-time data with the server. This function facilitates users to ensure the stability and efficiency of device control and data transmission in complex network environments, and improves the scalability and adaptability of the system.

[0075] It is not difficult to find that in the embodiment of the present application, through the integration of multiple functions such as power management, communication configuration, image display, aging test and equipment management, not only the safety and efficiency of equipment operation are improved, but also the user's operating experience is greatly improved. Compared with the traditional decentralized management method, this system realizes comprehensive and automated control of the micro-display system, and has significant advantages in accuracy, flexibility and efficiency.

[0076] Third embodiment

[0077] The third embodiment of the present application relates to a micro display detection method, which is applied to the above system, such as Fig.14As shown, the method includes:

[0078] S101, establishing communication with the video signal image generation module through the host computer module, and using the MQTT protocol to transmit control instructions and data;

[0079] S102, the host computer module downloads the point screen configuration, initialization code and timing file of the micro display to the video signal image generation module through the MQTT protocol;

[0080] S103, connecting the video signal source, the video signal image generation module and the micro display through the control interface module to realize the transmission and processing of the video signal;

[0081] S104, sending instructions to the video signal image generation module through the host computer module to control the micro display to perform display test operations, including screen dot, image display, screen switching and parameter adjustment.

[0082] The host computer module completes the communication with the video signal image generation module through MQTT, including:

[0083] The establishment of the MQTT client, the host computer connects to the lower computer through the MQTT protocol. The MQTT client of the host computer connects to the MQTT server through the specified IP address and port number, and after a successful connection, subscribes to the relevant topic to receive feedback information from the lower computer.

[0084]

[0085]

[0086] Send and receive commands. When the host computer successfully connects to the MQTT server, it can send commands to the subordinate computers by publishing messages. For example, the screen can be turned on by publishing the "PanelOn" command.

[0087]

[0088] After issuing instructions, the upper computer receives feedback information from the lower computer by subscribing to specific topics.

[0089] The lower computer will perform corresponding operations according to the instructions and feed back the execution results to the upper computer.

[0090]

[0091]

[0092] Execution and feedback of screen click instructions. When the upper computer sends a screen click instruction, the lower computer receives the instruction and executes the relevant operation. After the operation succeeds or fails, the lower computer feeds back the corresponding status to the upper computer through MQTT, including the following statuses:

[0093] Success: The display lights up normally, and the host computer receives the feedback message "Panel opened successfully".

[0094] Failure: The display screen fails to light up, and the host computer receives the feedback message "Panel opening failed".

[0095] Timeout: The lower computer fails to respond within the specified time, the upper computer processes the timeout and feedbacks the message "Open Timeout".

[0096]

[0097]

[0098] MQTT disconnection and reconnection

[0099] If the connection between the MQTT client and the server is disconnected, the host computer will automatically perform a disconnection process and try to reconnect. This function ensures that the system can resume communication in the event of network anomalies.

[0100]

[0101] It can realize reliable communication between the upper computer and the lower computer based on the MQTT protocol, and realize the control and monitoring of the display screen. Compared with traditional communication methods, the MQTT protocol has the following advantages: lightweight protocol, suitable for resource-constrained devices, low communication overhead; high real-time performance, able to quickly transmit instructions and receive feedback, suitable for scenarios with requirements on response time; support message confirmation mechanism to ensure accurate transmission and execution of instructions.

[0102] It is not difficult to find that in the embodiments of the present application, the method is flexible in detection and easy to expand, and more functional modules can be added according to needs, such as power management, aging test, etc., which is suitable for the management and control of various micro display devices.

[0103] The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the scope of protection of this patent.
