Capacitive Touch Panels
Projected capacitive (PCAP) touch panels on glass or film, with no moving parts and no gaskets to leak. Multi-touch, glove and wet-touch modes, LED backlight and an optional printed graphic layer — engineered as one sealed unit for your product.
A capacitive touch panel senses your finger through changes in an electric field, using a grid of electrodes behind a glass or film surface. Because there is no membrane to flex and no opening to seal, the entire front of your product can be one flat, sealed, wipe-clean surface.
A transparent electrode grid creates a small electric field across the panel. Your finger disturbs that field when it touches the surface; the controller reads the change at each intersection and reports an exact X/Y position. Firmware maps those positions to buttons, sliders or gestures.
Rectangular, circular, curved or edge-to-edge panels from 2" to 24"+ diagonal.
Printed legends, logos and icons beneath the touch surface — flat, protected and sealed.
LED backlight behind legends and buttons for readability in dark environments.
Boosted sensitivity for gloves up to 5 mm and water-rejection algorithms for wet panels.
I2C, USB or UART controllers with custom sensitivity, debounce and gesture tuning.
Bonded cover glass or film to display for better clarity, durability and sunlight readability.
Adhesive tape, snap-fit frames or metal brackets to drop into your enclosure.
Shielded constructions and ESD hardening for noisy industrial environments.
