Cypress adds 100th capacitive touchscreen patent to IP portfolio

SAN JOSE, USA: Cypress Semiconductor Corp. announced the US Patent Office has issued Cypress its one hundredth patent related to its TrueTouch capacitive touchscreen controllers.

The patent, numbered 8,610,443, relates to attenuator circuits that contribute to the TrueTouch Gen5 family's unmatched immunity to electrical noise from chargers and displays, which can render touchscreens for smartphones, superphones, tablets, e-readers and other portable devices unusable. Cypress is continuing to expand its intellectual property (IP) portfolio at the industry's highest rate with more than 200 patents pending, protecting the competitive advantage of its TrueTouch offerings and their differentiating features.

In addition to patents related to noise immunity, Cypress's patented DualSense technology allows TrueTouch solutions to execute both self-capacitance and mutual-capacitance measurements in the same device. This enables the Gen5 family to offer the industry's best waterproofing for seamless performance in real-world conditions, including the presence of rain, condensation or sweat. Cypress also holds patents related to panel construction, mutual capacitance sensing, scanning methods, setting baselines, and tracking and identification of fingers, styluses and other objects.

Cypress is demonstrating its TrueTouch portfolio in customer meetings at the Consumer Electronics Show in Las Vegas, Nevada from January 7-10, 2014.
