Cypress Semiconductor Corp. announced that its TrueTouch® Gen4 controllers enable the “Magic Touch” feature in the new Ascend Mate smartphone from HUAWEI, which boasts one of the world’s largest smartphone touchscreens at 6.1 inches. Magic Touch lets users accurately navigate the touchscreen even with thick gloves on, solving a persistent problem for customers in cold-weather climates. The Gen4 TrueTouch controller also enables the Ascend Mate to offer outstanding water rejection and unmatched touchscreen performance in the presence of electronic noise sources.

The Magic Touch feature is enabled with patent-pending technology from Cypress available on Gen4 that is unavailable from other suppliers. The Gen4 family delivers an array of technologies the competition cannot match. It is the world’s only controller family with built-in 10V Tx to drive the touch panel at 10V. Because 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. The Gen4 family also makes use of Cypress’s patented self plus mutual capacitance sensing technology.

TrueTouch is the only solution with the ability to execute both self-capacitance and mutual-capacitance measurements in the same device—and switch dynamically between the two in application. These capabilities enable both the Magic Touch and water rejection features on the Ascend Mate.

The HUAWEI Ascend Mate combines superior performance with a unique set of features, ensuring end customers have an optimal touchscreen user experience. Its screen-to-body ratio is 73%, one of the highest in the industry, maximizing viewing pleasure for emails, video and games. The 6.1-inch HD IPS+ LCD screen has a resolution of 1280 x 720 for unsurpassed clarity and color accuracy. The Ascend Mate is also very slim, with a thickness of just 6.5 mm at its narrowest part.

"We’re excited to team with HUAWEI on this outstanding smartphone," said John Carey, Senior Director of TrueTouch Marketing at Cypress. “The Ascend Mate showcases many of the reasons that TrueTouch is the premier touchscreen solution in the industry.”
