ZTE, the world's leading provider of telecommunications equipment, network solutions and mobile devices, has selected Cypress Semiconductor's TrueTouch capacitive touch screen controller for its customer's flagship nubia Z7 Max smartphone.
The phone uses a TrueTouch TMA568 controller to implement a gesture function that is easy to wake up. This feature allows users to wake up their screen from sleep mode simply by double-tapping the screen with their fingers.
The nubia Z7 Max contains a 5.5-inch full HD touch screen with powerful waterproof functions driven by the TMA568 controller. The controller brings the most accurate gloved finger tracking function to the mobile phone, and has the ability to automatically switch between glove and finger tracking without requiring the user to change the settings of the mobile phone. In addition, the TrueTouch controller has the world's highest immunity to electrical noise generated by chargers and displays, providing reliable touch input in real environments where competing solutions suffer from errors and missed touches.
Ni Fei, CEO of the nubia brand, said: "We have a long-term relationship with Cypress and continue to be impressed by the company's technology leadership in touch screen technology." We continue to strive to provide customers with world-class features The TrueTouch controller allows us to provide unique features that enhance the user experience and differentiate our nubia series. "
Joe Montalbo, vice president of Cypress's TrueTouch business unit, added:" We are proud that nubia chose TrueTouch to bring reliable touchscreen performance and differentiated functionality to another world-class nubia smartphone. "Our easy-to-wake gesture feature is another powerful example of how TrueTouch provides innovative ways to improve the user experience, and it fits perfectly with the feature-rich nubia Z7 Max." The TrueTouch solution can also drive the touch screen of nubia X6, Z5S, Z5S Mini and Z5 mobile phones.
The electronic noise generated by the display and the after-sales charger will destroy the normal operation capability of the touch screen. Cypress's Charger Armor function provides unprecedented 40V peak-to-peak (Vpp) charger noise immunity, measuring range from 1 to 500kHz, with ultra-thin 0.5mm cover mirror and a maximum finger size of 22mm-for measurement The controller with the strictest specifications of any touch screen. Under these conditions, there is no competing controller that can provide more than 15Vpp immunity.
With Cypress's patented DualSense technology, self-capacitance and mutual-capacitance measurements can be performed on the same device, and the TrueTouch controller provides the industry's best waterproof performance to meet actual conditions including rain, condensation, or sweat To achieve seamless performance. By combining this powerful architecture with the industry-leading 32-bit ARM Cortex M-core processor known for its efficient MIPS / mW, the TrueTouch controller has a 120Hz refresh rate and low power consumption. The company said that these controllers drive the touch screen at a high frequency of 10V through narrow-band, single-scan and advanced hardware DSP filtering.
