Description

Technical Field

[0001] The present invention relates to the technical field of display modules, and in particular to an intelligent production method for Incell display modules that integrates optical testing and cross-validation. Background Art

[0002] The following significant technical defects currently exist in the production process of Incell display modules:

[0003] 1. Separation of processes leads to low efficiency: Touch (TP) testing, display testing, display firmware burning, and optical testing are performed at independent workstations, resulting in low equipment utilization and high efficiency losses due to repeated positioning. In addition, the touch and display testing processes lack a cross-verification mechanism, resulting in a missed defective product rate (either missed touch testing or missed display testing) exceeding the quality control warning value, seriously affecting product quality.

[0004] 2. Serious data silos: An effective database linking optical parameters (such as flicker and color gamut) with firmware burn data has yet to be established, and test data storage is relatively fragmented. This necessitates data retrieval and analysis across multiple systems for quality traceability, increasing both difficulty and time. Summary of the Invention

[0005] The purpose of this application is to provide an intelligent production method for Incell display modules that integrates optical testing and cross-validation, which is used to solve technical problems such as process separation, missed detection, and data islands in traditional production processes.

[0006] To achieve the above application objectives, the technical solutions adopted in this application are as follows:

[0007] The present invention provides an intelligent production method for InCell display modules that integrates optical testing and cross-validation, including:

[0008] (1) The optical probe and the burner perform optical parameter testing and firmware burning simultaneously;

[0009] (2) Add display ID verification during the touch test phase and TP firmware register verification during the display test phase;

[0010] (3) Establishing a composite database, which includes optical parameter data, burned firmware version, and verification log, wherein the verification log includes the first verification data of the touch test phase and the second verification data of the display test phase;

[0011] (4) The entire process of "optical testing and firmware burning - cross-verification - unified data archiving" is completed through a single power-on, and a dynamic interlocking mechanism is introduced between processes. If any link is abnormal, the process will be terminated immediately to ensure product quality.

If the ID value does not match the expected value, it is determined that the display phase test has failed. During the display test phase, the register data in the TP firmware is read and compared with the preset data to verify whether the TP has been tested.

[0015] Optionally, when an abnormality occurs in any process of optical parameter testing, firmware burning, touch testing and display testing, the system sends a warning signal and immediately stops the entire production process to prevent the production of unqualified products.

[0016] Optionally, a specific method for verifying the TP test execution status in the display test phase includes:

[0017] During the touch test phase, an additional data burning step is added to burn the preset data into the flash memory of the TP firmware or the designated vacant register;

[0018] In the display test phase, the register data in the TP firmware is read and compared with the preset data to verify whether the touch test phase has been correctly executed.

[0020] Use an optical probe to test the brightness of each screen of the Incell display module and record the brightness value of each screen;
