• industrial touch screen monitor
• projected capacitive touch

Why an industrial touch screen monitor registers ghost taps near drives and chargers, and how capacitive controllers use hop scanning to reject that noise.

• noise immunity

VFD switching noise pushes an industrial capacitive touch screen from smooth input to cursor jitter. Tuning, grounding and layout bring the taps back.
