Capacitive Touch Cover-Glass Thickness Calculator
Capacitive (PCAP/CTP) touch controllers struggle as cover-glass thickness grows. This tool estimates the maximum cover-glass thickness your touch layer can reliably sense, and flags when you need a bridge-ITO or metal-mesh solution.
Cover-glass setup
Pick the touch architecture and your target thickness.
FAQ
Why does thickness limit touch?
Mutual-capacitance coupling between the finger and the sensor decays with distance. Standard ITO sensors reliably sense through ~1.0 mm glass; beyond that signal-to-noise drops and false touches rise.
Can I use a thick cover with gloves?
Glove and wet-finger operation needs lower coupling thresholds and often a metal-mesh or DITO sensor, plus firmware tuning. Plan for ≤0.7 mm effective sensing for gloved use.
When do I need the cover-glass thickness calculator?
Use it when specifying a projective-capacitive (PCAP) touch display, especially for outdoor, industrial, or gloved-use designs. It balances impact resistance and IK rating against touch sensitivity so the glass survives drops yet still senses reliably.
We design cover glass, sensor, and bonding for your application.
