PCAP Touch Screens

Projected capacitive touch built for the field — multi-touch, gloved-hand operation, and pristine optical clarity in environments that destroy consumer-grade panels.

How PCAP Works

Projected capacitive (PCAP) touch sensing uses a precise grid of conductive electrodes — typically patterned ITO or metal mesh — laminated between glass layers. When a finger or capacitive stylus approaches the surface, it disturbs the electrostatic field at each grid intersection. A controller measures those tiny capacitance changes thousands of times per second to pinpoint touch location with sub-millimeter accuracy.

Why It Matters in the Field

Unlike resistive touch, PCAP requires no mechanical deflection — meaning no moving parts to wear out, no flex layer to puncture, and no calibration drift over thousands of hours of use. The sensor lives behind a thick layer of chemically strengthened cover glass, so the user-facing surface is essentially unbreakable under normal field abuse.

Multi-Touch and Gesture Support

PCAP natively supports 10+ simultaneous touch points, enabling pinch-zoom, rotate, and complex gesture control on modern HMI software. For operators transitioning from consumer tablets to industrial equipment, the interaction model feels immediately familiar.

Engineered for Gloves, Water, and Sunlight

Mildex tunes its PCAP controllers and sensor stacks for the specific conditions each customer faces. Thick winter gloves, surgical gloves, rain on the cover glass, salt spray, EMI from nearby radios — each environment demands a different sensitivity profile and noise-rejection strategy. Off-the-shelf PCAP modules fail here. Tuned modules don't.
