Projected Capacitive (PCAP)

Touch Technology

Projected Capacitive (PCAP) touch screens offer the user friendly multi-touch experience, associated with smartphones and tablets, operating with very light touch through a highly durable glass surface.

A D Metro’s projected capacitive touch screen kits provide a high quality Glass on Glass sensor construction bundled with a discrete controller board, for commercial applications.

A D Metro’s PCAP innovations include a patented group controller, where a common controller serves a range of screen sizes to simplify design and reduce inventory costs. The controller offers USB-HID compatibility with major operating systems, simplified product development and accelerated time to market.

ARGON PCAP Controller

A D Metro’s industry leading ARGON PCAP controller senses and adapts, at the press of a button, to the connected (off-the-shelf) PCAP sensor size, format, and cover glass as well as the characteristics of detected touches and your system’s unique background noise environment.

Standard PCAP Controller

A D Metro’s standard Projected Capacitance (PCAP) controllers along with A D Metro’s wide range of PCAP sensors deliver a high-quality, multi-touch solution suitable for a wide range of applications.

How do Projected Capacitive Touch Screens Work?

Projected capacitive touch screen sensors use two perpendicular layers of conductive coatings that form vertical and horizontal patterned tracks behind a glass top layer. When a finger is placed on the glass screen it changes the mutual capacitance between the horizontal and vertical patterned tracks. The controller scans each cell of the horizontal and vertical grid with a high frequency signal, identifying any changes in mutual capacitance between adjacent cells as touch locations.

Resistive

A D Metro’s resistive touch products include two styles of sensors. Choose either our conventional, standard resistive sensors or our patented ULTRA armored resistive sensors. ULTRA sensors are proven in the most physically demanding touch applications.

Infrared Optical

An infrared touch screen application is composed of a frame outfitted with LEDs and photodetectors. The frame has an optical bezel or protective cover that enables LEDs to emit infrared beams, invisible to the naked eye.

Surface Acoustic Wave (SAW)

A D Metro offers a complete line of Surface Acoustic Wave (SAW) touch screens kits, consisting of touch screen and controller. SAW offers an excellent alternative for many touch applications requiring a light touch, excellent optical characteristics and a very durable surface.
