Huawei has designed TrueTouch Gen4 capacitive touchscreen controllers from Cypress Semiconductor) into five of its newest smartphones. These controllers drive the touchscreen interface on Huawei’s economical new Honor 3X and 3C smartphones, as well as on its Ascend G716, G730, and G740 smartphone models.
Huawei is one of the world’s fastest-growing smartphone manufacturers, and is currently ranked in the No. 3 position in terms of worldwide unit sales last year with year-over-year growth up 67.5%, according to estimates from the market research firm IDC.
Gen4 delivers best-in-class immunity to electrical noise from sources such as after-market chargers and displays, and it enables leading water tolerance. This combination provides accurate touch input and finger tracking in environments where competing solutions experience false and missed touches. The TrueTouch portfolio’s features are backed by more than 100 capacitive touch sensing patents.
Commenting Shuo Zhang, vice president of worldwide mobile sales at Cypress said, “Cypress TrueTouch offers unmatched signal-to-noise ratio performance, enabling a superior user interface experience. It also delivers features such as hover, proximity sensing, stylus support, waterproofing, and charger noise mitigation that significantly enhance the user experience and preserve battery life.”
TrueTouch Gen4 controllers deliver an array of technologies. The Gen4 employs 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, passive stylus support, and face detection features, as well as TrueTouch’s water rejection capability.
