Abstract

A touch panel module includes a substrate, a sensor layer disposed on the substrate, a first glue layer disposed on the sensor layer and an anti-electromagnetic interference layer disposed on the first glue layer. The touch panel module with anti-electromagnetic interference can be formed independently, and may be combined with other electronic device to form a touch device, thereby reducing the thickness of the touch device and simplifying the process steps.
