Description

Technical Field

[0001] This invention relates to the field of display module production traceability technology, and in particular to a display module production traceability method and system. Background Technology

[0002] TFT display modules are widely used in the display market, such as smart bracelets, smartwatches, smart home devices, and e-cigarettes. With the advancement of technology, more and more consumer products such as smartwatches and bracelets are becoming increasingly popular. TFT display modules have their own price advantage, which gives them a large share of the consumer smartwatch market.

[0003] As smartwatches are shipped in increasing numbers, many defective products have also emerged. These defective TFT display modules cause a lot of inconvenience for both customers and factories, requiring significant manpower, materials, and time to process and analyze them. This limits the further expansion of TFT display modules in the consumer electronics market.

[0004] To meet market demand and reduce costs, it is necessary to continuously optimize TFT display module solutions, systematically collect and analyze the proportion and types of defective TFT display modules, and fully trace the production data of shipped TFT display modules. This will enable the production end to effectively control and reduce the generation of defective products, and reduce the investment of customers and factories in handling defective products in the market, thereby promoting the further development of TFT screen display modules.

[0054] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are all within the scope of protection of this invention.

[0055] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0058] The purpose of this application is to propose a method and system for tracing the production of display modules, so as to solve the problem that there are too many defective TFT display modules in existing consumer products, and that analysis and processing require too much manpower and resources.

[0059] Firstly, a method for tracing the production of display modules, such as... Figure 1 , Figure 1 A flowchart of an embodiment of a display module production traceability method according to this application; including:

[0060] S100: Obtain the first ID and corresponding information file of each display module 503 under test using the production time, production part number and production line, and burn the first ID into the first driver module 5031 of the display module 503 under test to obtain the second ID.

[0061] In a preferred embodiment, such as Figure 2 , Figure 2 yes Figure 1 A flowchart of a specific implementation of S100; S100 includes: S110, representing the production line number and time in sequence with corresponding hexadecimal numbers and setting them sequentially in the data sequence; S120, arranging the production material number after the time number to obtain the first ID.

[0062] In this embodiment, the central control module 501 generates a first ID for each display module 503 to be tested. The first ID is a coding sequence consisting of the generation time, the generated material number, and the production line.

[0063] In this embodiment, the central control module 501 can be a central control center composed of a computer cluster or a single computer.

[0064] like Figure 8 , Figure 8 This is a comparison diagram of each data digit of the ID sequence in this application with hexadecimal numbers. The production time includes year, month, and day. The year is represented by the last digit, and the month and day are represented by their corresponding hexadecimal numbers in sequence. The production line is also represented by its corresponding hexadecimal data in sequence. The material number can be composed of a four-digit code and set after the ID.

[0065] As shown above, the data sequence format structure of the first ID is as shown in Table 1:

[0066] Table 1. First ID Data Sequence Format Structure

[0067] First Second place Third place Fourth place Fifth to eighth Production line Year moon day Material Number

[0068] In practice, the first ID consists of 8 hexadecimal digits. For example, the first digit indicates the production line, the second digit is the last digit of the production year, the third digit is the production month, the fourth digit is the production date, and the fifth, sixth, seventh, and eighth digits represent the sample part number. For example, the second sample produced on June 25, 2024, on line 8 would have the ID 846S0002.

[0069] In a preferred embodiment, such as Figure 3 , Figure 3 yes Figure 2 A flowchart of a specific implementation method following S120; after S120, S100 further includes:

[0070] S130, The first ID is burned into the first driver module 5031 of the display module under test 503; S140, The first ID is distributed to the second driver module 502 of the traceability system.

[0071] In this embodiment, the first driving module 5031 can be the driving IC of the display module 503 under test, used to drive the display screen of the display module 503 under test to light up. The second driving module 502 is used to drive and control the first driving module 5031, test the driving IC, and return the test data and corresponding ID to the central control module 501.

[0072] In practice, the central control module 501 burns the first ID into the first driver module 5031 through the second driver module 502, and at the same time distributes the first ID to the second driver module 502. Before the formal test, the second driver module 502 determines whether the first driver module 5031 is abnormal by comparing the first ID, that is, whether the driver IC of the display module 503 under test is normal.

[0073] S200: Read back the second ID and compare it with the first ID. If they do not match, generate the first abnormal sub-ID and save the abnormal information in the first abnormal sub-ID. The test of the current display module 503 is terminated.

[0074] In a preferred embodiment, such as Figure 4 , Figure 4 yes Figure 1 A flowchart of a specific implementation of S200 is shown below; S200 includes: S210, reading back the second ID using the second driving module 502; S220, comparing the second ID with the first ID using the second driving module 502, and if they do not match, returning the comparison result and the corresponding first ID to the central control module 501 of the traceability system; S230, generating a first abnormal sub-ID corresponding to the first ID based on the comparison result, and storing the abnormal content in the first abnormal sub-ID.

[0075] In this embodiment, before driving the display module 503 under test to light up, the driver IC of the display module 503 under test, namely the first driver module 5031, is tested. Specifically, the second driver module 502 reads the second ID from the first driver module 5031 and compares it with the first ID obtained from the distribution. If they match, the driver IC of the display module 503 under test is normal. If they do not match, the display module 503 under test is determined to be defective. The second driver module 502 needs to return the comparison result and its corresponding first ID to the central control module 501. The central control module 501 then generates a first abnormal sub-ID based on the first ID and saves the abnormal information of the test into the first abnormal sub-ID for traceability, statistics and analysis.

[0076] S300. If the second ID is consistent with the first ID, the driver will turn on the display module 503 under test, display multiple test screens in sequence to perform the test, and save the test process and each test result in the corresponding information file.

[0077] In a preferred embodiment, such as Figure 5 , Figure 5 yes Figure 1 A flowchart of a specific implementation of S300; S300 includes: S310, the first driving module 5031 lights up the display module 503 under test according to the instruction of the second driving module 502 and displays the test screen; S320, if the current test screen is normal, the next test screen is displayed.

[0078] In this embodiment, the second driving module 502 provides initialization code to the first driving module 5031 and controls the first driving module 5031 to drive the test screen of the display. When the test screen is working normally, the test continues and the test results are returned to the central control module 501 through the second driving module 502.

[0079] In a preferred embodiment, such as Figure 6 , Figure 6 yes Figure 5 A flowchart of a specific implementation method following S320; following S320, S300 further includes:

[0080] S330. The second drive module 502 controls the first drive module 5031 to drive the display module under test 503 to display the specified test screen; S340. The test module 504 acquires the CIE data and power consumption information of the specified test screen and transmits it to the central control module 501 of the traceability system; S350. The central control module 501 saves the CIE data and power consumption information in the information file of the corresponding first ID.

[0081] In this embodiment, the test screen can be white. The CS410 probe of the test unit of the test module 504 will measure the CIE data when the screen is white and record the power consumption at this time. The data will be sent back to the host computer to generate the corresponding ID file and recorded.

[0082] In a preferred embodiment, such as Figure 7 , Figure 7 yes Figure 5 The flowchart of another specific implementation after S320; after S320, S300 also includes: S360, if the current test screen is abnormal, the first ID and abnormal information content of the display module 503 under test are returned to the central control module 501 through the second drive module 502; S370, the central control module 501 generates a second abnormal sub-ID corresponding to the first ID, and saves the abnormal information content in the second abnormal sub-ID.

[0083] When a test screen is abnormal, the operator can select the NG key through the operation button of the first drive module 5031. At this time, the second drive module 502 will return the test result to the central control module 501. The central control module 501 generates a second abnormal sub-ID based on the test result. The operator can input a simple text description of the abnormality of the test screen through the second drive module 502 and save it to the second abnormal sub-ID.

[0084] S400: Based on the first ID, read the information file corresponding to the first ID to trace the display module. By burning a corresponding ID to each display module and saving the test process and test information to the corresponding ID, when a display module malfunctions, an malfunction sub-ID is generated to save the malfunction content. Based on the ID, the test process and test results of the display module product can be traced. Not only can the display module be quickly traced based on the ID to understand the test process, but also defective products can be systematically and scientifically statistically analyzed using big data. This provides an important data foundation for the subsequent production of display modules, solving the problem of too many defective TFT display modules in existing consumer products, which requires too much manpower and resources for analysis and processing.

[0087] The display module under test 503 includes a first drive module 5031;

[0088] The central control module 501 is communicatively connected to the first drive module 5031, the second drive module 502, and the test module 504 respectively. The first drive module 5031 is also communicatively connected to the second drive module 502 and the test module 504.

[0089] The central control module 501 is used to obtain the first ID and corresponding information file of each display module 503 under test using the production time, production part number, and production line number. It then burns the first ID into the first driver module 5031 of the display module 503 under test, obtains the second ID, saves the returned test results to the corresponding information file, determines whether to generate a first abnormal sub-ID and a second abnormal sub-ID based on the test results, and saves the abnormal information to the first abnormal sub-ID and the second abnormal sub-ID respectively.

[0090] The first driving module 5031 is used to drive the display module under test 503 according to the instructions of the second driving module 502, and to provide its own first ID to the test module 504;

[0091] The second drive module 502 is used to control the first drive module 5031, and read back the first ID from the first drive module 5031. It compares the first ID with the second ID. If they are inconsistent, it returns the corresponding first ID and the test result to the central control module 501.

[0092] The test module 504 is used to test multiple test screens displayed, and to test the CIE data and power consumption data of the specified test screens, and return the results to the central control module 501.

[0093] In conjunction with the display module production traceability system of the second aspect of the present invention, in a first possible embodiment, the central control module 501 includes:

[0094] The acquisition unit is used to sort the production line number and time according to the hexadecimal number order and set them in the ID sequence, placing the production material number after the time sequence to obtain the first ID.

[0096] The determination unit is used to compare the second ID with the first ID. If they are inconsistent, it is determined that the first driving module 5031 of the display module 503 under test is abnormal and the display module 503 under test is a defective product.

[0097] Compared with the prior art, the embodiments of this application have the following main technical effects: by burning a corresponding ID to each display module and saving the test process and test information to the corresponding ID, when an abnormality occurs in the display module, an abnormal sub-ID corresponding to the ID is generated to save the abnormal content. Based on the ID, the test process and test results of the display module product can be traced. Not only can the display module be quickly traced based on the ID to understand the test process of the display module, but also defective products can be systematically and scientifically statistically analyzed using big data, providing an important data foundation for the subsequent production of display modules. This solves the problem of too many defective TFT display modules in existing consumer products, which requires too much manpower and resources for analysis and processing.
