Problems solved by technology

[0002] Generally speaking, the processing method of touch panels adopts a layer-by-layer lamination process, which may easily cause inaccurate lamination alignment, increase the thickness and weight of the touch panel, and reduce the light transmittance and touch sensitivity of touch products. degree, it is difficult to greatly improve product quality
When processing the sensing layer, a large amount of transparent conductive material needs to be etched away to form the corresponding sensing line pattern, resulting in a large amount of etching waste liquid and serious environmental pollution; moreover, the color difference of the touch panel is large, and the etching traces are obvious
