Cypress Semiconductor has announced that Huawei has selected its TrueTouch capacitive touchscreen solution for its next-gen MediaPad X2 tablet PC. The PC utilises the TrueTouch TMA568 controller’s gloved finger tracking, robust water tolerance and easy-wake gestures for its sleek 7” touchscreen display. Users can make calls, surf the web, play games, take pictures and use other key features even if they are wearing thick gloves or the screen is wet. In addition, the easy-wake gestures feature enables users to perform a double-tap gesture to quickly activate the device from sleep mode.

The MediaPad X2 is claimed to be the industry’s thinnest tablet with a 7” display at just 7.18mm thick, enabled in part by the TrueTouch solution’s capability to support ultra-thin stackup layers in the touchscreen. The PC’s high-resolution display delivers a crisp and dynamic visual experience, along with a flawless response to touch commands. The controller enables outstanding tracking of fingers in gloves of various materials and thicknesses, and automatically switches between glove and finger tracking without requiring the user to switch settings. TrueTouch employs the industry’s highest tolerance to water and immunity to electronic noise from aftermarket chargers and displays, enabling accurate touch input for the MediaPad X2 in environments where competing solutions experience false and missed touches.

The controller features Cypress’s patented DualSense technology that executes both self-capacitance and mutual-capacitance measurements in the same device. The result is the industry’s best water rejection and wet finger tracking for seamless performance in real-world conditions, including the presence of rain, condensation or sweat. Additionally, DualSense technology delivers immunity to charger noise of up to 35Vpp from 1-500kHz, with a 0.5mm cover lens and a 9mm-wide finger.

“We are pleased to follow up the selection of our TrueTouch solution for the MediaPad X1 with this win for Huawei’s impressive MediaPad X2,” said Joe Montalbo, Vice President of the TrueTouch Business Unit, Cypress. “This design win is one of many with Huawei, and underscores our ability to provide touchscreen features and reliability that enable our customers to differentiate their products.”
