[0029] Since the upper surface of the lower substrate is provided with a traceability code, when a customer returns a defective product, the TFT module can be removed and the traceability code on the lower substrate can be checked, thereby realizing batch tracking, tracing back to the manufacturing situation at that time, and then eliminating defects in a targeted manner, thereby eradicating defective products and improving product competitiveness. And since the traceability code is formed by the ITO trace, it can be integrally formed with the ITO pattern, thereby reducing manufacturing costs.

[0030] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

And since the traceability code 21 is formed by an ITO wiring, it can be integrally formed with the ITO pattern, thereby reducing the manufacturing cost.

[0032] Furthermore, the traceability code 21 is printed with the date, version information and batch record, so that the production date, version information and batch record can be traced.
