This enables it to work even with quad high definition displays. ![]() The device also provides all types of SYNC mode (HSYNC and VSYNC) support, which enables touch sampling to be synchronized with the display SYNC signal. The device supports multi-finger glove operation and small passive stylus. The water rejection algorithm can detect water on the top of the screen and the device can still track one finger moving in the water without false touch or line breaking. The device utilizes ST proprietary hardware and firmware techniques to reduce power significantly in low power active mode and in low power idle mode, and incorporates multiple TX driving methods that can further boost the SNR and report rate.įingerTip supports advanced features thanks to multi-mode sensing technology. ![]() FingerTip provides support for curved displays through proprietary node compensation hardware.įingerTip's low-noise capacitive analog front-end provides enhanced noise suppression capabilities for various noise sources such as display, 3-phase noise and severe common mode noise introduced by battery chargers. One or two layer ITO sensors are supported using glass or PET substrates. This offers the flexibility to use FingerTip with multiple touchscreens using different ITO designs and overlay materials. The touch acquisition analog front-end has a wide dynamic range capable of coping with touchscreens of different sizes and configurations. ![]() Coupled with the internal processor, the FingerTip touchscreen controller can detect, classify and track 10 finger touches with fast a report rate and response times. FingerTip provides an optimal mix of low power, small size, low external part count and versatile features with unmatched true multi-touch performance in a single-chip touchscreen controller.įingerTip uses a dedicated capacitance-to-voltage acquisition engine to implement the touch sensing.
