Problems solved by technology

The inventors of the present application found in the process of implementing the application that due to the structural characteristics of the dam, a depression with a large step difference will be formed between the inner dam and the outer dam. When connecting wire 06, short circuit between touch wires 06 is often caused due to insufficient exposure of the photoresist in the recess, such as Figure 1b S, which affects the realization of the touch display function of the product, and the yield rate is low
