Gen4 TrueTouch Controller Enables Industry’s Best Tracking of Gloved
Fingers; Strong Customer Design Support Driving Broad Smartphone
The HUAWEI Ascend G700, A199 and Ascend G610 smartphones each use a Gen4 controller, while a Gen3 controller drives the Ascend G526 touchscreen. The Gen4 family utilizes Cypress’s patented DualSense™ technology to execute both self-capacitance and mutual-capacitance measurements in the same device, and switch dynamically between the two in application. This ability enables glove tracking, stylus support, face detection to avoid unintended touches when on a call, and TrueTouch’s unrivaled water rejection capability.
"We’re pleased to have HUAWEI select TrueTouch to augment their reputation for delivering high-quality smartphones with innovative features," said
Gen 4 delivers an array of technologies that competing solutions cannot match. It is the world’s only controller family with built-in 10V Tx to drive the touch panel at 10V. Because Signal to Noise Ratio (SNR) is directly proportional to the voltage at which the panel is driven, this feature allows Cypress to sense smaller signals than the competitors in the presence of high noise sources.
Cypress’s touch-sensing portfolio is the industry’s broadest and most well adopted, encompassing TrueTouch, CapSense®, and TrackPad solutions. The company’s IP portfolio is unmatched, including true, single-layer sensor solutions for dramatically reduced touchscreen costs and self and mutual capacitance sensing on the same chip that enables advanced features such as waterproofing, proximity sensing, support for 1-mm stylus, and hover.
Cypress’s TrueTouch technology provides the industry’s best noise immunity, highest SNR, fastest refresh rates, lowest power consumption, and world’s best accuracy and linearity. The flexible TrueTouch solution allows customers to rapidly develop leading-edge solutions without having to buy turnkey modules. They have a choice of using touch sensors (glass or film) and LCDs from preferred partners, and can develop innovative mechanical designs ranging from flat to curved surfaces of varying thickness. In addition, TrueTouch devices offer Cypress’s legendary noise immunity with patented capacitive sensing technology that enables flawless operation in noisy RF and LCD environments.
