Most of the existing testing methods test each item separately, and when all items are qualified, the LED module is judged to be qualified. However, in the subsequent application of LED modules, it is found that when the test results of different items of the same LED module just meet the qualified standards, the probability of failure of the LED module during application is much greater than that of other LED modules.

[0063] Embodiment 1

[0064] like Figures 1 to 5 As shown, the LED module display effect intelligent testing method of the present invention specifically includes the following steps:

[0065] S1. Divide the LED module into a number of test unit modules according to the size of the LED module to be tested, and associate each test unit module with its corresponding position on the LED module;

[0066] Step S1 is to divide the LED module to be tested into several test unit modules and associate each test unit module with its corresponding position on the LED module, so as to accurately obtain the display effect of each test unit module in subsequent tests, so as to comprehensively evaluate the overall performance of the LED module; specifically, S1 includes the following aspects:

[0067] S11, measuring the size of the LED module, including length, width and thickness, and such size information is used in the subsequent division and position association process;

[0068] S12, dividing the LED module into a number of relatively uniform test unit modules according to the size of the LED module by a uniform division method, ensuring that each test unit module has a similar size;

[0069] S13, associating each test unit module with a corresponding position on the LED module through a coordinate system, ensuring that each position on the LED module corresponds to a specific test unit module;

[0070] In this step, by measuring the size of the LED module and evenly dividing it, the similar size and uniform distribution of the test unit modules are ensured. By using the coordinate system to associate each test unit module with the corresponding position on the LED module, an accurate mapping relationship is established. In the subsequent test process, the test results of each test unit module can be accurately identified and recorded, thereby achieving an accurate evaluation of the overall performance of the LED module.

[0071] By dividing the LED module into test unit modules of similar size, standardized testing of each module can be achieved, which helps to eliminate the differences between different areas of the LED module and ensure the comparability of the test results. Standardized testing is the prerequisite for achieving a comprehensive evaluation of the overall performance of the LED module, and can fully and objectively understand the display effect of the LED module in each area;

[0072] By associating the test unit module with the position on the LED module, an efficient and accurate method is provided for subsequent testing, which can quickly locate a specific area during the test process, improve the efficiency of the test, and ensure the accuracy of the test results;

[0073] In summary, step S1 ensures the accurate association between the test unit module and the LED module, laying the foundation for the subsequent comprehensive test of the display effect of the LED module, thereby achieving a comprehensive and accurate performance evaluation.

[0074] S2. Determine LED module test items, where the LED module test items include viewing angle test, brightness test, color test, response time test, and contrast test;

[0075] In the display effect test of LED modules, the reasonable selection of test items is crucial to comprehensively evaluate the performance of LED modules; the following is a detailed explanation of each test item:

[0076] S21. Viewing angle test. This test involves the visual performance of LED modules at different viewing angles. The viewing angle test usually includes horizontal and vertical directions to ensure that the display effect of the LED module is consistent in all directions. The viewing angle test can evaluate whether the LED module can maintain a good display effect when the observer's position changes in actual use.

[0077] S22. Brightness test. Brightness is an important parameter of LED display, which is directly related to the visibility of LED module under different ambient light conditions. Through brightness test, it can ensure that LED module can still provide clear display effect under different brightness requirements;

[0078] S23, Color Testing, this project involves the performance of the LED module in displaying colors; Color testing includes the evaluation of the accuracy and saturation of different colors, as well as the performance of the LED module in displaying colorful images;

[0079] S24, response time test. Response time is the time required for the LED module to switch display content. A lower response time helps reduce blur or afterimage effects in dynamic images. The response time test can ensure that the LED module performs well when displaying dynamic content.

[0080] S25. Contrast test. Contrast is the difference between brightness and darkness in a displayed image, which directly affects the clarity of the image. Contrast test helps evaluate the difference between dark and light colors displayed by LED modules to provide images with more depth and clarity.

[0081] In this step, by covering multiple test items, the display effect of the LED module can be fully and comprehensively evaluated. The comprehensive evaluation can fully understand the performance of the LED module, rather than just focusing on a single performance indicator, making the test closer to the actual use scenario of the LED module, increasing the reliability and practicality of the test results; multi-dimensional performance evaluation can identify the advantages and disadvantages of the LED module in different aspects and provide clear improvement directions;

[0082] Through comprehensive evaluation of multiple test items, it is possible to predict problems that may occur in actual applications and identify potential failures in advance, thereby improving the quality and reliability of LED modules;

[0083] In summary, the LED module test items determined in step S2 are helpful to comprehensively evaluate the performance of LED modules from multiple perspectives.

[0084] S3. According to the determined LED module test items, each test unit module is tested one by one to obtain a project test result information set corresponding to the test unit module; the project test result information set includes a viewing angle test result, a brightness test result, a color test result, a response time test result, and a contrast test result;

[0085] In the intelligent test method for LED module display effect, the S3 stage is to test each test unit module one by one to obtain the relevant project test result information set, to ensure that the performance of each small area LED module in each test is accurately evaluated, so as to build a comprehensive LED module display effect three-dimensional feature matrix; the execution method of each LED module test project includes:

[0086] S31, performing a viewing angle test, performing a viewing angle test on each test unit module, observing the LED module at different angles, and recording the visual effects of the LED module in different directions;

[0087] S32, perform brightness test, use a photometer to perform brightness test on each test unit module, and ensure that the brightness of each small area of ​​the LED module meets the requirements;

[0088] S33, performing a color test, using a spectroradiometer to measure the accuracy and saturation of the color displayed by the LED module on each test unit module;

[0089] S34, performing a response time test, using an oscilloscope to perform a response time test on each test unit module to ensure that the LED module responds quickly when switching display content;

[0090] S35, performing a contrast test, using an image quality analyzer to test the difference between dark and light colors displayed by the LED module on each test unit module;

[0091] S36. Record the result information of each test one by one to form a project test result information set, which includes the specific test results of each test unit module in terms of viewing angle, brightness, color, response time and contrast.

[0092] In this step, by testing each test unit module one by one, it is ensured that the performance of each small area of ​​the LED module is comprehensively and accurately evaluated, which helps to find potential problems and optimization space; dividing the LED module into test unit modules allows for more detailed testing of each small area, and detailed area evaluation helps to detect local performance problems and improve the sensitivity of detection;

[0093] By obtaining the specific test result information set of each test unit module, the performance problem of the specific area can be traced back, and the root cause of the problem can be accurately located, providing substantial data support for improving and optimizing the production process of LED modules; one-by-one testing ensures that each small area is fully and detailed tested, which can improve the overall quality of the LED module and reduce product defects caused by local performance problems;

[0094] In summary, the S3 step enables comprehensive performance assessment, problem solving, improved quality and customer satisfaction, and better presentation of results through data visualization.

[0095] S4, aligning the project test result information set with the position of the test unit module to obtain a three-dimensional feature matrix of the LED module display effect;

[0096] In step S4, the generation of the three-dimensional feature matrix of the display effect of the LED module is the core step. By integrating and spatially correlating the project test result information, the relationship between the various test results of the LED module and their corresponding positions in the LED module is comprehensively analyzed;

[0097] The test results obtained by each test unit module are matched with its position in the actual LED module to obtain a three-dimensional characteristic matrix of the LED module display effect, in which the test results of the same items of different test unit modules are located in the same plane, and the positions of the test results correspond to the positions of the test unit modules in the actual LED module; the test results of different items of the same test unit module are located in the same vertical column;

[0098] like Figure 2 As shown, Vn represents the viewing angle test result of the nth test unit module, Bn represents the brightness test result of the nth test unit module, Coln represents the color test result of the nth test unit module, Rn represents the response time test result of the nth test unit module, and Conn represents the contrast test result of the nth test unit module.

[0099] In this step, by corresponding the test results of each test unit module to the position in the actual LED module, the various test data of the LED module can be presented in a comprehensive matrix. This structured arrangement makes the understanding and comparison of the data more intuitive;

[0100] By matching the test results with the actual module positions, the test results of different areas of the LED module can be clearly displayed in the matrix, providing spatial information for subsequent analysis; the problematic areas or unit modules can be quickly located in the matrix, which helps to quickly identify faulty and low-performance areas;

[0101] By integrating the test results, the overall performance of the LED module can be comprehensively evaluated, rather than limited to the analysis of a single test result. The overall performance of the LED module can be comprehensively evaluated to find the correlation and influencing factors between different test items. After identifying the problem areas, targeted improvements and optimizations can be made to improve the overall quality and performance of the LED module.

[0102] In summary, the three-dimensional characteristic matrix of LED module display effect generated in step S4 provides a visual and comprehensive data basis for comprehensive performance evaluation, helping the test team to fully understand the test results of the LED module, and quickly identify, locate and improve problems in practical applications, thereby improving the overall quality and performance of the LED module.

[0103] S5, inputting the LED module display effect three-dimensional feature matrix into a pre-built LED module display effect evaluation model to obtain LED module display effect evaluation parameters;

[0104] The LED module display effect evaluation model construction method comprises:

[0105] S51. Collect historical LED module test data, including the results of various test items and performance in actual applications; the data includes various LED module types, sizes and manufacturers to ensure that the model has good generalization ability;

[0106] S52. Clean and preprocess the collected data, including removing outliers, standardizing data, and processing missing values;

[0107] S53. Select a deep learning model based on the complexity of the problem and the characteristics of the data;

[0108] S54. Design the model architecture, including the number of network layers, the number of nodes in each layer, and the choice of activation function;

[0109] S55, dividing the data into a training set and a test set;

[0110] S56. Use the divided training set to train the model. During the training process, the model gradually adjusts parameters through back propagation and optimization algorithms so that the model can get a better fit on the training data.

[0111] S57. Test the model on the validation set and adjust the model’s hyperparameters based on the performance.

[0112] S58. Integrate the trained model into the LED module testing process to ensure the correct preprocessing of input data and the interpretability of output results.

[0113] In this step, by collecting and cleaning a large amount of historical LED module test data, we ensure that the model's training data is of high quality and can accurately reflect the actual LED display effect. The use of deep learning models can better capture the complex characteristics of LED display effects and improve the accuracy and reliability of evaluation. The diversity and generalization of data ensure that the model has good generalization ability and can adapt to the display effect evaluation of various LED module types, sizes and manufacturers, rather than just being applicable to specific types of modules. The division of training sets and validation sets and the tuning of the model help avoid overfitting and ensure that the model can make more accurate predictions for unseen data.

[0114] Integrating trained models into the LED module testing process can automate the evaluation process, accelerate the evaluation process, and provide timely results; through the trained model, more informed decisions can be made based on actual data, thereby improving the design, manufacturing and application of LED modules and improving the overall quality;

[0115] In summary, this step can improve the accuracy, generalization ability and efficiency of LED module display effect evaluation, making the evaluation process more scientific and reliable, thereby providing better support and guarantee for the development and application of LED display technology.

[0116] S6, obtaining the power consumption of the LED module during the test time, and performing weighted calculation on the LED module display effect evaluation parameter and the LED module power consumption to obtain an LED module performance evaluation index;

[0117] Before testing the LED module, connect the LED module to the power consumption measuring device, measure and record the power consumption of the LED module during the test time through the power consumption measuring device, and obtain the power consumption of the LED module during the test time;

[0118] The method for obtaining the LED module performance evaluation index includes:

[0119] S61. Assign weights to different test items and power consumption according to actual application requirements and the use environment of the LED module;

[0120] S62, normalizing the parameters to ensure that the LED module display effect evaluation parameters and power consumption data are on the same scale;

[0121] S63 , performing weighted summation on the normalized LED module display effect evaluation parameters and power consumption data according to weights to obtain an LED module performance evaluation index.

[0122] In this step, by weighting the display effect evaluation parameters and power consumption of the LED module, a comprehensive performance evaluation index can be obtained. The index not only takes into account the display quality of the LED module, but also integrates its power consumption during the test time, making the evaluation more comprehensive and realistic.

[0123] Personalized weight allocation ensures that the evaluation index is more in line with the requirements of specific applications, so that the performance of LED modules in actual applications can be evaluated more accurately; the parameters are normalized to ensure that the LED module display effect evaluation parameters and power consumption data are on the same scale, which can avoid unfair trade-offs caused by the absolute value of the parameters, so that each parameter can contribute equally in the evaluation; by taking multiple factors into account, including display effect, power consumption, etc., the evaluation index is more comprehensive, allowing users to fully understand the performance of LED modules;

[0124] In summary, step S6 can provide a comprehensive LED module performance evaluation method, taking into account multiple factors, making the evaluation more objective, comprehensive and in line with actual application needs.

[0125] S7, comparing the LED module performance evaluation index with a preset threshold value, if the LED module performance evaluation index is lower than the preset threshold value, the LED module is determined to be unqualified; if the LED module performance evaluation index is not lower than the preset threshold value, the LED module is determined to be qualified;

[0126] The factors affecting the setting of the preset threshold include:

[0127] S71. Consider product specifications and requirements. LED modules are used for specific applications, and each application has different performance requirements. Product specifications and requirements directly affect the setting of preset thresholds, ensuring that the LED modules can meet the requirements in specific applications.

[0128] S72. Consider industry standards. The industry will have some standards and specifications that define the performance parameters and quality standards of LED products. The setting of preset thresholds should refer to industry standards and specifications to ensure that the LED modules meet the quality requirements recognized by the industry.

[0129] S73. Considering the user experience requirements, the LED module is designed to provide a good user experience. The setting of the preset threshold needs to consider the user's expectations for brightness, color accuracy, etc. to meet the user experience requirements;

[0130] S74, considering environmental factors. The setting of the preset threshold value will be affected by the use of the LED module under different environmental conditions. Therefore, the preset threshold value needs to take these environmental factors into consideration.

[0131] S75. Considering technical feasibility and manufacturing costs, setting too strict a threshold will lead to increased production costs, while setting too loose a threshold will sacrifice product quality.

[0132] In this step, by setting a preset threshold, the performance evaluation index of the LED module needs to meet specific standards, which can ensure that the LED product meets specific industry standards and specifications and guarantees product quality and reliability;

[0133] The setting of preset thresholds allows LED modules to be optimized according to the needs of specific applications, ensuring their performance in specific environments; the setting of preset thresholds can ensure that the brightness, color accuracy and other aspects of LED products meet user expectations and provide a better user experience; the setting of preset thresholds can ensure that LED products can provide consistent performance in various environments, thereby enhancing the reliability and stability of the product; the setting of preset thresholds can reduce manufacturing costs while ensuring product quality, and produce high-quality LED modules within a reasonable cost range; through the setting of preset thresholds, manufacturers can optimize production processes, adjust production parameters to meet specific performance requirements, improve production efficiency and ensure product consistency;

[0134] In summary, the steps of evaluating LED module performance and comparing it with preset thresholds can ensure that LED products meet specific requirements and standards, improve product quality, meet user needs, and effectively control manufacturing costs and production efficiency.
