These problems not only affect the display effect of the LED large screen, but may also pose a threat to the visual health of viewers.

[0003] Currently, when LED screen display effects malfunction, the common practice is to divide the LED screen into multiple areas and check each area and parameter one by one. This often makes it difficult to find abnormal data, takes a long time, and relies heavily on the professional knowledge and experience of maintenance personnel, resulting in low maintenance efficiency.

[0033] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0034] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0035] To address the aforementioned technical problems, this disclosure provides a method for controlling a display screen. This will be described in detail through one or more of the following embodiments.

[0036] The display screen control method provided in this disclosure is applicable to LED large screen control scenarios. This method can be executed by a display screen control device, which can be implemented in software and / or hardware and can be integrated into an electronic device. The electronic device can include, but is not limited to, mobile terminals such as smartphones, laptops, digital radio receivers, personal digital assistants (PDAs), tablet PCs, portable multimedia players (PMPs), in-vehicle terminals (e.g., in-vehicle navigation terminals), wearable devices, etc., as well as fixed terminals such as digital televisions, desktop computers, smart home devices, etc.

[0037] Figure 1 This is a flowchart illustrating a display screen control method provided in an embodiment of the present disclosure. The method is applied to a control device, which is connected to both a host computer and a display screen, and is capable of interacting with both. It can be understood that the host computer controls the display screen through the control device, specifically including the following... Figure 1 The following steps are shown:

[0038] S101: Receive the setting command sent by the host computer, and in response to the setting command, generate origin information according to the first configuration parameters on the display screen.

[0039] Among them, the origin information is used to characterize the configuration parameters that the display screen has when it is displaying normally.

[0040] Understandably, users can send setting commands to the control device via a host computer. These setting commands instruct the control device to generate origin information. The control device responds to these commands, acquiring the first configuration parameters of the display screen. These parameters include size, resolution, brightness, contrast ratio, pixel pitch, refresh rate, color gamut, and input / output interfaces. The first configuration parameters can also be configuration parameters related to the receiving card, including input / output interfaces, maximum control area, maximum number of control pixels, performance parameters, and communication protocol. Subsequently, the first configuration parameters are either directly saved as origin information or pre-processed before generating origin information. For example, pre-processing could involve fine-tuning the first configuration parameters based on the screen's appearance, such as adjusting the resolution from 1920x1080 to 3840x2160. Other specific methods for generating origin information from configuration parameters are not limited and can be set according to user needs.

[0041] Understandably, the display screen has a normal display effect under the first configuration parameters. The normal display effect can be defined by the user according to the control requirements of the display screen. For example, the normal display effect refers to the best display effect or the best screen effect. Here, the screen effect refers to the quality and visual experience of the images or videos presented by the display screen. The screen effect is affected by factors such as resolution, refresh rate, brightness, contrast, and viewing angle. The above configuration parameters can be specific parameters for configuring each factor that affects the screen effect.

[0042] S102, Receive control commands sent by the host computer.

[0043] Among them, the control commands are generated by the host computer when the display effect on the screen is different from the normal display effect.

[0044] Understandably, based on the above S102, after the control device completes the setting of the origin information, it can send a response message to the host computer indicating that the setting is complete. Subsequently, during the host computer's monitoring of the display screen's effect, if it finds that the display screen's effect has changed compared to the normal display effect, that is, the display effect is different from the normal display effect, which is a display abnormality, such as blurry images or ghosting, then a control command is generated and sent to the control device. The control command refers to the control command issued by the user in response to the abnormal screen effect.

[0045] S103. In response to control commands, adjust the display effect of the display screen based on the origin information.

[0046] Understandably, based on the above S103, the control device responds to the control command and performs corresponding control on the display screen based on the origin information, such as restoring the origin information to restore the display screen to normal display effect, and / or comparing the origin information to understand the abnormal parameters that cause the display abnormality. This will be explained in detail in the following embodiments.

[0047] The control commands include comparison commands. In response to these control commands, the display effect of the screen is adjusted based on the origin information. This can be achieved through the following steps:

[0048] In response to a comparison command, the second configuration parameters of the display screen are obtained; the second configuration parameters and the origin information are compared to generate a comparison result; wherein the comparison result includes at least one abnormal parameter that causes the display effect to differ from the normal display effect.

[0049] The specific implementation process for comparing origin information is understandable and is as follows: First, the second configuration parameter of the display screen is obtained. The first acquisition time of the first configuration parameter and the second acquisition time of the second configuration parameter are different, and the second acquisition time is after the first acquisition time. Then, the origin information and the second configuration parameter are compared to identify at least one abnormal parameter. For example, if the resolution setting in the origin information is a first value, and the resolution setting in the second configuration parameter is a second value, and the second value is significantly greater than the first value, then the resolution is considered an abnormal parameter. An abnormal parameter refers to the configuration parameter that causes the abnormal display effect. Users can then quickly understand the abnormal parameters causing the display effect change based on the comparison results for further maintenance. That is, each comparison can compare all parameters involved in the origin information and the second configuration parameter. Compared to comparing each region and parameter individually, this method can efficiently and quickly locate abnormal parameters, reducing maintenance time. Furthermore, since there are significant differences in the parameters, users can adjust them themselves, making maintenance more flexible. Alternatively, multiple parameters can be selected from all parameters for comparison according to the comparison requirements.

[0050] The control commands include recovery commands. In response to these commands, the display effect of the screen is adjusted based on the origin information. This can be achieved through the following steps:

[0051] In response to the recovery command, the origin information is parsed to obtain the third configuration parameter; the display screen is configured according to the third configuration parameter to restore the display screen to its normal display effect.

[0052] Understandably, the specific process for restoring the origin information is as follows: The origin information is parsed to determine the third configuration parameter. The third configuration parameter and the first configuration parameter may have slight differences due to different parsing methods, but the display effect provided to the user is normal or optimal. If the origin information is directly saved from the first configuration parameter, then the first and third configuration parameters are completely identical. Subsequently, the third configuration parameter is set as the display screen's configuration parameter to restore the changed screen effect to the original information's screen effect. Alternatively, if only the configuration parameter is saved from the origin information, the origin information is directly set as the display screen's configuration parameter, i.e., the configuration parameter is restored to the origin information.

[0053] For example, Figure 2 This disclosure provides a control timing diagram for a display screen, specifically a timing diagram illustrating the interaction between a host computer, a control device, and the display screen. Figure 2 As shown, the first sequence is as follows: the host computer sends a control command to the control device (hereinafter referred to as the device) to set the origin information, and the device saves the configuration parameters of the display screen as the origin information; the second sequence is as follows: when the screen effect changes, the host computer sends a control command to the device to compare the origin information, and the device compares the configuration parameters of the display screen with the origin information and returns the comparison result to the host computer; the third sequence is as follows: when the screen effect changes, the host computer sends a control command to the device to restore the origin information, and after parsing the origin information, the device sends a command to the display screen to restore the screen effect to the screen effect of the origin information.

[0054] The display control method provided in this disclosure facilitates subsequent data recovery by storing the origin information of the device. It also supports comparing the display's configuration parameters with the origin information and displaying the comparison results. This helps users troubleshoot problems and locate abnormal parameters when screen effects change. Furthermore, the display's configuration parameters can be restored to the origin information to help users quickly recover parameters when screen effects change, ensuring a smooth viewing experience. By setting, comparing, and restoring origin information, users can easily manage their display.

[0055] Based on the above embodiments, Figure 3 This is a schematic flowchart of another display control method provided in this embodiment of the disclosure, illustrating the diagnostic interaction process between the host computer and the control device, specifically including, as follows: Figure 3 The following steps are shown:

[0056] S301: Receive diagnostic commands sent by the host computer.

[0057] Understandably, the host computer can also send diagnostic commands to the control device. These commands instruct the user to perform self-tests or full-link tests. Self-tests refer to the device automatically checking its hardware status to help the user troubleshoot problems. Full-link tests refer to the testing of the entire chain, including the control device, photoelectric converter, and receiver card, to help the user eliminate communication problems throughout the chain.

[0058] S302. In response to a diagnostic command, obtain the current status of the device corresponding to the diagnostic command.

[0059] Understandably, based on the above S301, the diagnostic command includes the device to be diagnosed, and the control device responds to the diagnostic command by obtaining the current status of the device to be diagnosed. The diagnostic command also includes multiple commands for detecting different aspects, and the control device performs corresponding diagnostics for each command, as detailed in the following embodiments.

[0060] The diagnostic commands include device self-test commands. In response to these commands, the current status of the device to be diagnosed is obtained, which can be achieved through the following steps:

[0061] In response to a device self-test command, the hardware status of the control device is obtained; the current status includes the hardware status, and the control device is the device to be diagnosed.

[0062] In one embodiment, the diagnostic command is a self-test command. In response to the self-test command, the control device obtains the hardware status, which refers to the working status of the various components included in the control device, including but not limited to the power module and signal processing unit.

[0063] The diagnostic command is a monitoring command received by the receiving card. The receiving card connects the control device and the display screen, and in response to the diagnostic command, obtains the current status of the device to be diagnosed. This can be achieved through the following steps:

[0064] In response to a monitoring command from the receiving card, the system acquires the communication data of the receiving card; and determines the communication status of the receiving card based on the communication data. The current status includes the communication status, and the receiving card is the device to be diagnosed.

[0065] The communication data includes signal interruption data of the receiving card during communication, signal quality data of the receiving card during communication, and / or communication error data of the receiving card within a set time period. The communication error data is used to monitor the cumulative error of the receiving card.

[0066] In another embodiment, the diagnostic command is a monitoring command for the receiving card, used to monitor the number of signal interruptions and the signal quality of the receiving card. The control device responds to this monitoring command by acquiring the communication data of the receiving card. This communication data includes the number of signal interruptions, the signal quality, and the cumulative bit error rate. The number of signal interruptions refers to the number of times the receiving card's signal is interrupted during communication; the signal quality refers to the quality of signal transmission during communication; and the cumulative bit error rate refers to the number of communication errors within a set time period, typically used to measure the reliability of a communication link or system. Subsequently, the communication status of the receiving card is determined based on the communication data. If the number of signal interruptions exceeds a set interruption threshold, the receiving card is determined to be in a communication abnormal state.

[0067] The diagnostic commands include screen detection commands. In response to these commands, the current status of the device to be diagnosed is obtained, which can be achieved through the following steps:

[0068] In response to a screen detection command, the status of each light-emitting device in the display screen is obtained; the current status includes the status of the light beads, and the display screen is the device to be diagnosed.

[0069] In another embodiment, the diagnostic command is a screen detection command for the display screen. The control device responds to this command by acquiring the status of the LEDs in each light-emitting device on the display screen. The light-emitting device can be an LED, and the LED status refers to the working condition of each individual LED in the LED display screen, including its brightness, color, and whether it is working properly. Subsequently, based on the LED status, LED frame errors can be diagnosed, that is, whether each LED is functioning correctly or faulty.

[0070] Understandably, the control device does not limit the execution sequence of the aforementioned screen detection commands, monitoring commands, self-test commands, comparison commands, and recovery commands, and users can set them according to their needs.

[0071] S303. Perform fault diagnosis based on the current status and generate a diagnostic report; the diagnostic report shall include at least the diagnostic details and corresponding maintenance recommendations.

[0072] Understandably, based on the above S302, fault diagnosis is performed according to the current status to determine the cause of the fault and the corresponding maintenance measures. A diagnostic report is generated and fed back to the host computer. The diagnostic report can be generated as a PDF file and can be exported to help users quickly maintain the equipment. The specific fault diagnosis method is not limited.

[0073] For example, see Figure 2The timing diagram shown represents the fourth possible timing sequence: The host computer sends a diagnostic command to the device. The device, based on the diagnostic command, obtains the status of the device to be diagnosed and returns the diagnostic results to the host computer. The diagnostic results may include receiver card failure or hardware failure, etc. One possible scenario is that after receiving the diagnostic results, the host computer generates a diagnostic report based on the results. The diagnostic report should at least include diagnostic details and maintenance recommendations. Another possible scenario is that the device directly generates a diagnostic report and returns it to the host computer.

[0074] Understandably, the control device can also feed back the monitoring data from the receiving card to the host computer, which can then perform subsequent fault analysis.

[0075] The display control method provided in this disclosure detects the hardware status of the device through self-testing, which can help troubleshoot device operation problems. Secondly, it can also diagnose the entire communication chain between the control device, photoelectric converter, and receiver card, including receiver card signal interruption coefficient and receiver card signal quality detection, which can help troubleshoot communication problems throughout the chain. Furthermore, the generated diagnostic report includes not only the cause of the fault but also effective maintenance recommendations, enabling users to quickly maintain the device.

[0076] Based on the above embodiments, Figure 4 This is a schematic diagram of a control system for a display screen provided in an embodiment of the present disclosure. The control system includes a host computer, a display screen, and a control device. The host computer includes a diagnostic control module and an information control module. The control device includes a photoelectric converter and a receiver card. The control device also includes a device diagnostic module and an information management module. The control device (controller) is used for device self-testing, origin information management, and data acquisition from the receiver card. The photoelectric converter is used to convert between electrical signals and optical signals. The receiver card is used to receive and decode the electrical signals converted by the photoelectric converter and suitable for the LED screen, and distribute the decoded electrical signals to the connected LED modules.

[0077] The information control module is used to send setting instructions and / or control instructions to the information management module; wherein, the control instructions are generated by the host computer when the display effect on the screen is different from the normal display effect;

[0078] The information management module is used to generate origin information based on the first configuration parameters of the display screen in response to a setting command; wherein, the origin information is used to characterize the configuration parameters that the display screen has when it is displaying normally; and / or, the information management module is also used to adjust the display effect of the display screen based on the origin information in response to a control command;

[0079] The diagnostic control module is used to send diagnostic commands to the device diagnostic module;

[0080] The equipment diagnostic module is used to respond to diagnostic commands, obtain the current status of the equipment to be diagnosed, perform fault diagnosis based on the current status, and generate a diagnostic report. The diagnostic report includes at least diagnostic details and corresponding maintenance recommendations.

[0081] Understandably, the signal control module in the host computer is used to send control commands for setting, comparing, and restoring origin information to the information management module in the control device. The diagnostic control module in the host computer is used to send control commands for device self-test, LED frame errors, cumulative bit errors, receiver card signal interruption counts, and receiver card signal quality to the device diagnostic module in the control device. Simultaneously, the diagnostic control module is also used to receive diagnostic results returned by the control device. For detailed implementation instructions, please refer to the above embodiments, which will not be repeated here.

[0082] Optionally, the control device also includes a receiver card data acquisition module, which is connected to the photoelectric converter. The photoelectric converter is also connected to the receiver card for data acquisition. The control device, the photoelectric converter, and the receiver card form a full-link communication system.
