Description

Technical Field

[0001] The present invention relates to the technical field of test classification of display modules, and in particular to an automated testing method and equipment for display modules. Background Art

[0002] During the product production process, automated equipment is used to test display modules. When testing display modules, multiple items are often tested as add-ons, generally including focus testing and white field image quality analysis (including IR stain test, IC stain test, bright bad pixel test, optical center test, shading test, etc.). Therefore, the test item results fed back to the robot by the detection module are only good or bad products. If a display module needs to test multiple sub-items at the same time for a certain test item, there is no way to classify them, and there is no way to know the test status of each item. For example, in white field image quality analysis (including IR stain test, IC stain test, bright bad pixel test, optical center test, shading test, etc.), if any sub-test item tests as bad, the robot can only classify it as bad and cannot further subdivide it. Summary of the Invention

[0003] When testing display modules, existing automated testing equipment does not subdivide sub-test items, resulting in staff being unable to understand the specific test status of the product, reducing the efficiency of subsequent processing.

[0004] To address the above issues, an automated testing method and equipment for display modules are proposed. This method categorizes the test items for the current display module according to environmental requirements, obtains multiple test items, and determines the priority of each sub-test item. The sub-test items are then tested sequentially according to the priority, and the test results are assigned values. The current display module information is then partitioned and stored based on the assigned values. This facilitates statistical analysis of test results, identifying areas with high defect rates, and thereby improving production processes. This increases test automation and accuracy, and addresses the problem of existing automated testing equipment, which, when testing display modules, fails to segment sub-test items, resulting in staff being unable to understand the specific test results of the product, reducing the efficiency of subsequent processing.

[0005] In a first aspect, a method for automatically testing a display module includes: Step 100: Classify the items that need to be tested for the current display module according to environmental requirements, obtain multiple test items, each of which includes multiple sub-test items, and determine the priority of each sub-test item; Step 200: Test the sub-test items in order of priority, assign values ​​to the test results, and partition and store the current display module information according to the assigned values.

[0006] In conjunction with the automated testing method for a display module according to the first aspect of the present invention, in a first possible implementation, step 100 includes: Step 110: Divide the test items into dark field test items and white field test items according to the test environment requirements. The white field test items include IR stain sub-test items, IC stain sub-test items, bright bad pixel sub-test items, optical center sub-test items, and shading sub-test items. Step 120 : Sort the IR stain sub-test item, IC stain sub-test item, bright bad pixel sub-test item, optical center sub-test item, and shading sub-test item from high to low according to their priorities.

[0007] In conjunction with the automated testing method for a display module according to the first aspect of the present invention, in a second possible implementation, step 200 includes: Step 210: Test each of the sub-test items according to their priority level to obtain a sub-test result. Step 220: judge the sub-test result. If the sub-test result is good, continue to test the sub-test item of the next priority.

[0008] In conjunction with the automated testing method for a display module according to the first aspect of the present invention, in a third possible implementation, step 200 includes: Step 230: Test each of the sub-test items according to their priority level to obtain a sub-test result. Step 240: judge the sub-test result. If the sub-test result is defective, assign a value to the sub-test result to obtain a defective value.

[0009] In conjunction with the third possible implementation manner of the first aspect of the present invention, in a fourth possible implementation manner, step 240 includes: Step 241: sequentially judging the subtest results of the plurality of subtest items; Step 242: If the test results of multiple sub-test items are judged as defective, different values ​​are assigned to the multiple sub-test results judged as defective.

[0010] In conjunction with the fourth possible implementation manner of the first aspect of the present invention, in a fifth possible implementation manner, step 200 further includes: Step 250: partition the storage units according to different assigned values; Step 260: Store the current display module information in the corresponding partition according to the sub-test results.

[0011] In a second aspect, an automated testing device for a display module adopts the automated testing method for a display module described in the first aspect, comprising: The classification module is used to classify the items that need to be tested on the current display module according to the environmental requirements, obtain multiple test items, each of which includes multiple sub-test items, and determine the priority of each sub-test item. The test module is used to test the sub-test items in order according to the priority, assign values ​​to the sub-test results, and partition and store the current display module information according to the assigned values.

[0012] In conjunction with the automated testing device for display modules according to the second aspect of the present invention, in a first possible implementation, the classification module includes: The sorting unit is used to sort the IR stain sub-test item, the IC stain sub-test item, the bright bad pixel sub-test item, the optical center sub-test item, and the shading sub-test item from high to low according to their priorities.

[0013] In conjunction with the automated testing device for the display module according to the second aspect of the present invention, in a second possible implementation manner, the testing module includes: An assignment unit is used to judge the sub-test result. If the sub-test result is defective, the sub-test result is assigned a value to obtain a defective value. If the test results of multiple sub-test items are judged to be defective, different values ​​are assigned to the multiple sub-test results judged to be defective.

[0014] In conjunction with the second possible implementation of the second aspect of the present invention, in a third possible implementation, the test module further includes: The storage unit is used to partition the storage unit according to different assignments, and store the current display module information in the corresponding partition according to the sub-test results.

[0015] The automated testing method and equipment for display modules described in the present invention categorizes the items to be tested on the current display module according to environmental requirements, obtains multiple test items, determines the priority of each sub-test item, tests the sub-test items sequentially according to the priority, assigns values ​​to the test results, and partitions and stores the current display module information based on the assigned values. This facilitates statistical analysis of test results, identifying high defect rates, and thus improving production processes, increasing test automation and accuracy.
