Cypress TrueTouch Controllers Provide Industry-Leading 1-mm Resistive Stylus Replacement Support For Capacitive Touchscreens

The traditional benefit of resistive touchscreens until now has been superior stylus support. Many Asian languages require enhanced character recognition for reliable text input, and therefore resistive technology continues to be used despite its poor durability and display quality. Cypress’s new TrueTouch controllers deliver a true “Resistive Stylus Replacement” (RSR) solution that matches the size and performance of resistive stylus implementations while providing the additional benefits of the capacitive touch solution. No other touch suppliers are currently able to provide this functionality, which enables lower cost feature phones as well as smart phones in Asia to shift to superior capacitive touchscreens from resistive technology.

“Cypress is unique in our ability to dynamically switch between self-capacitive and mutual-capacitive sensing methods,” said Dhwani Vyas, vice president of the User Interface Business Unit at Cypress. “This advantage allows us to be the only touchscreen controller supplier that can deliver Resistive Stylus Replacement, and positions us to introduce new, unique features going forward that our customers can use to differentiate their end products, especially for the Asian market. The touchscreen revolution is just getting started, and Cypress technology such as RSR will help to drive it forward.”

The new families provides all the traditional benefits of Cypress’s TrueTouch technology, including very high signal-to-noise ratio of more than 80:1 RMS, low power consumption (less that 1.3 mA low-power state current), best-in-class water rejection and wet-finger tracking, and more. In addition, they provide highly accurate stylus tracking accuracy better than 0.7 mm, along with 120Hz refresh rates for full handwriting recognition.
