Resistive multi-input panels


Fujitsu Components America, Inc., has begun marketing its Windows® 7 logo-certified, resistive multi-input panels in North America. Already in production in Japan since August 2009, the new multi-input panels' increased functionality promises to expand touch capability into many new applications and markets, including harsh environments.

Using Fujitsu's proprietary technology, the resistive multi-input panels can process single-tap and multi-touch input from nearly any object using varying pressure - e.g., a heavy-glove finger, credit card edge, standard pens, a light finger touch, etc. This capability results in accurate, stylus-handwriting input and enables two-finger manipulation, including pinch, push, rotate and scroll functionality.

Both finger and stylus action can be performed simultaneously, with the panels supporting up to 32 simultaneous touch points. Initial target applications include netbooks and mobile medical and industrial devices. Compared to capacitive touch panels, Fujitsu's resistive multi-input panels are lightweight, durable, and offer excellent performance in a variety of operating environments. They feature low power consumption, high resolution, high accuracy, low EMI, and register finger or stylus input even when wet.

Although inherently capable of scaling up to larger dimensions, Fujitsu will first offer the custom panels in 5.6- to 12.1-inch sizes. Controller boards, ICs and drivers are readily available to facilitate panel integration.
