Smartphones powered by STMicroelectronics touchscreen controller

Semiconductor company STMicroelectronics has revealed that its FingerTip touchscreen controller (TSC) is powering all three of the latest Xiaomi Mi8 smartphone models — Standard, SE and Explorer.

The FingerTip touch controllers for both small and large screens provide an optimal mix of ultralow power, small size and low external part count. The ST-proprietary low-noise capacitive analog front-end ensures low intrinsic noise, providing the high sensitivity required in AMOLED displays. The innovative node compensation hardware provides consistent touch performance throughout the display panel, including curved and trench areas.

FingerTip’s main processor implements a powerful 32-bit ARM Cortex-M3 core that is capable of providing a high level of overall touch performance in noise rejection and response time and can detect, classify and track as many as 10 finger touches at once.

“ST’s industry-proven FingerTip touch-screen controller technology enables advanced multitouch UI on many devices with a single-chip solution, with high and uniform sensitivity on all panels, including curved screen areas and new AMOLED displays, making it perfectly suited for the latest smartphone designs,” said Giuseppe Noviello, Application Specific Product BU Director, Analog Custom Product Division, STMicroelectronics.
