Wacom Introduces New Capacitive Touchscreen Technology

By DE Editors

Wacom (Vancouver, WA) announced a new capacitive touchscreen technology called Reversing Ramped Field Capacitive (RRFC) touch, to be publicly unveiled at the International Society for Information Display exhibition, May 20 to 22, 2008, in Los Angeles, CA.

Wacom's patent-pending technology uses newly designed low-power circuitry and what the company describes as "revolutionary reversing ramped electro-static fields to deliver pinpoint precision and drift-free performance to touchscreen users."

The technology can be integrated into dual-input applications with Wacom's EMR pen-input technology for Tablet PC OEMs or work by itself on other platforms that require only a finger touch interface. With this newly developed technology, Wacom can provide flexibility to OEM partners seeking best-in-class interface solutions.

Wacom's RRFC touch technology uses new static field engineering for increased stability and drift-free performance. With advanced ASIC design and high resolution signal processing, RRFC touch is effectively immune to noise. It is also the only surface capacitive touch technology that can demonstrate excellent accuracy, stability, and sensitivity even when working on battery power, says the company.

Wacom touchscreens have greater transmissivity of up to 95 percent, compared to transmissivity of only 80 to 85 percent in resistive capacitive touchscreens. To date, Wacom's pen and resistive touch systems can be found on the convertible notebook computers including Lenovo, HP, Toshiba, and Gateway.
