ZTE's nubia Phones Use Cypress TrueTouch Gen4 Touchscreen Controllers

ZTE may not be as popular a name as Samsung or Apple in North America, but sales of its devices in China and other areas of the world have certainly propelled the company to a strong position in the global smartphone market. The company largely produces Android devices — although it has released a Firefox OS device or two in the past — so naturally its latest flagship series of smartphones also sports the Google-made OS.

The premium nubia Z5S and nubia Z5S Mini were introduced late last year as an answer to high-end devices from HTC and Samsung. As such, they feature the kind of top-of-the-line specs and features one would expect — such as Qualcomm’s latest Snapdragon chips, HD display resolution and 13-megapixel cameras. Recently, it was revealed that ZTE had selected Cypress Semiconductor’s TrueTouch Gen4 capacitive touchscreen controllers for the nubia Z5S and Z5S Mini as well.

In particular, the devices use the Gen4 TMA463 controller to deliver superior finger tracking and sensitivity on their multitouch displays. The controller also enables an easy-wake gesture for both phones, allowing users to activate them from sleep mode with a customized gesture, such as a double tap.

Cypress’ TrueTouch Gen4 offers best-in-class immunity to electrical noise from sources like after-market chargers and displays, while also enabling a high degree of water tolerance. This allows for accurate touch input and finger tracking in environments that typically cause touchscreens to experience false and missed touches.

"Cypress's TrueTouch solution gave us the touchscreen performance and differentiating features we wanted for the launch of our nubia brand with the original Z5 smartphone," said Ni Fei, general manager for the nubia brand at ZTE, in a statement. "With the Gen4 controller, the Z5S and Z5S Mini meet our same high standards for touchscreen performance, and integrate improvements such as the easy-wake gesture for an even better user experience."
