Touch panel design improves linearity, increases touch input area

fujitsu5wireSunnyvale, Calif. — Fujitsu Components America Inc. has added a new line of RoHS-compliant, 5-wire resistive touch panels to its product offering. The panels feature a new design construction that improves linearity and allows OEMs to maximize the active touch input area especially in large-size and wide-aspect ratio displays.

The film-glass touch panels use a proprietary detection method that enables narrow frame borders in large touch panels (e.g.: 9mm for 15-inch size) with an edge-area linearity performance of +/- 2 percent. This allows more of the active display area to be used for touch input functionality, said Fujitsu. Target applications include POS systems and kiosks for the retail, restaurant and hospitality markets.

Other panel specifications include a minimum operating life of 35 million touches, 80 to 85% transmissivity, an operating environment of -20°C to +60°C degrees, and 20% to 90% relative humidity. A USB controller, cables and driver software are also available.

Fujitsu’s initial 5-wire release is a 15-inch panel for 4:3 displays, which complements the company’s existing 4-wire and 7-wire resistive touch panel lines.

Availability: Summer 2009.
