ZTE, a leading global provider of telecommunications equipment, network
solutions and mobile devices, has selected a TrueTouch capacitive
touchscreen controller from Cypress Semiconductor for its flagship nubia Z7
Max smartphone.
The phone uses the TrueTouch TMA568 controller to implement an easy-wake
gesture feature that enables the user to wake the phone's screen from
sleep-mode by simply double tapping on the screen with a finger.
The nubia Z7 Max includes a 5.5-inch full HD touchscreen with robust water
tolerance driven by the TMA568 controller. The controller brings the
market's most accurate gloved finger tracking to the phone and the ability
to automatically switch between glove and finger tracking without requiring
the user to change the phone's settings. Additionally, TrueTouch controllers
deliver the world's highest immunity to electrical noise from chargers and
displays, delivering reliable touch input in real-world environments where
competing solutions experience false and missed touches, says the company.
"We have a long-standing relationship with Cypress and continue to be
impressed with the company's technical leadership in touchscreen
technology," said Ni Fei, CEO of the nubia brand. "We continually strive to
provide our customers with world-class features, and TrueTouch controllers
enable us to offer the unique features that enhance the user experience and
differentiate our nubia line."
"We are proud that nubia has chosen TrueTouch to bring reliable touchscreen
performance and differentiating features to another world-class nubia
smartphone," added Joe Montalbo, vice president of the TrueTouch Business
Unit, Cypress. "Our easy-wake gesture feature is another strong example of
how TrueTouch provides innovative ways to improve the user experience, which
fits in well with the feature-rich nubia Z7 Max." TrueTouch solutions also
drive the touchscreens of the nubia X6, Z5S, Z5S Mini and Z5 phones.
Electronic noise from displays and after-market chargers can disrupt a
touchscreen's ability to operate properly. Cypress's Charger Armor feature
delivers unprecedented 40V peak-to-peak (Vpp) charger noise immunity
measured from 1 to 500kHz with an ultra-thin 0.5mm cover lens and a
finger-size up to 22mm-the most stringent specifications used to measure any
touchscreen controller. No competing controllers deliver noise immunity over
15Vpp under these conditions.
With Cypress's patented DualSense technology to execute both
self-capacitance and mutual-capacitance measurements in the same device,
TrueTouch controllers offer the industry's best waterproofing for seamless
performance in real-world conditions, including the presence of rain,
condensation, or sweat. By combining this powerful architecture with an
industry leading 32-bit ARM Cortex M-Core processor that is known for
high-efficiency MIPS/mW, TrueTouch controllers boast 120Hz refresh rates and
low power consumption. The controllers drive the touchscreen at 10V and at
high frequency with narrow-band, single-pass scanning and advanced hardware
DSP filtering, says the company.
