Grounding Touch Controller

Grounding Touch Controller

Why is Grounding the Controller Important? 

Proper grounding is essential to protect the touch sensor from electromagnetic interference (EMI) and ensure stable performance.

How to Ground the Touch Controller

To ground the system:

  • Connect the ground cable from the touch controller to a metal part of the LCD chassis (the rear metal frame behind the sensor).

  • This connection discharges electrical noise and prevents EMI from affecting touch performance.

⚠️ Important: Grounding is mandatory and should never be skipped.

Ground Connector Location

The ground wire connector is located next to the USB port on the touch controller.
