Touch Panel Module Anti-EMI Layer Integration

Solution Overview

Problem

Traditional touch panels face challenges with increased thickness and complex manufacturing processes due to the need for an additional anti-electromagnetic interference layer, which complicates their integration with other electronic components.

Innovation Solution

The anti-interference conductive layer is directly formed on an adhesive layer within the touch panel module, eliminating the need for a separate substrate and simplifying the manufacturing process, while maintaining anti-electromagnetic interference functionality.

AI summary

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.
