Description

[0001] The present application relates to the technical field of factory information tracing, and particularly relates to a display module factory information tracing method and system. BACKGROUND
[0002] Nowadays, mobile terminal customers will require module factories to leave module production information on the module, including but not limited to production manufacturer, production date, product line body, batch, main material (IC and glass) manufacturer and the like. Customers can identify the relevant production information of different modules, which is convenient for after-sales analysis and also facilitates the module factory to read and trace analysis. The general method is to print a code on the backlight or print a two-dimensional code on the FPC (or print the two-dimensional code into a label and attach it to the FPC).
[0003] For example, a product anti-counterfeiting method disclosed in Chinese patent application CN 104933569 A obtains product information of a product to be shipped, a special label recognition area is provided on the product to be shipped, the label recognition area is provided with visible scale lines in a square grid pattern; the product information is input into a product verification website to generate a first verification code and a first two-dimensional scanning code including a product verification website link, and the first two-dimensional scanning code and the first verification code are associated with the product to be shipped, and the first verification code is saved in the product verification website; a second verification code and a second two-dimensional scanning code including a product verification website link are generated according to the generated first two-dimensional scanning code and the first verification code, and the second verification code and the second two-dimensional scanning code are associated with the product to be shipped, and the second verification code is saved in the product verification website.
