Cypress Semiconductor Corp. today announced that HUAWEI has selected its TrueTouch® controllers to drive the touchscreens in four HUAWEI smartphones. Two of the models leverage a TrueTouch Gen4 controller to deliver accurate navigation of the touchscreen even with thick gloves on, preventing users from having to remove their gloves in cold-weather climates.
Gen 4 also delivers best-in-class touchscreen performance in the presence of electronic noise from after-market chargers and displays that can render touchscreens inoperable – a major problem plaguing the industry. Huawei selected Cypress based on the strong design support offered by the TrueTouch team in China, as well as for TrueTouch’s industry-leading performance and features.
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 Shuo Zhang, vice president of worldwide mobile sales at Cypress. “Demand for smartphones in China is quickly growing, and the strong design support from our dedicated team there has helped to quickly grow TrueTouch wins with a broad range of emerging handset makers. We are honored to be the key touchscreen controller provider to HUAWEI.”
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.
Touch Leadership
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.
