In a single-chip touchscreen controller, FingerTip offers the ideal balance of low power, small size, low external part count, diverse capabilities, and unrivalled real multi-touch capability.Touch sensing is implemented by FingerTip using a specialised capacitance-to-voltage acquisition engine.
The FingerTip touchscreen controller can detect, categorise, and track 10 finger touches with a quick report rate and reaction time when combined with the inbuilt processor.
The Global Fingertip touchscreen controller market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Due to the multi-mode sensing technology, ST’s FingerTip enables additional sophisticated functions including glove, thick cover, water, unique gestures, grip rejection, proximity detection, force sensing, and quick report rate for gaming applications.
The main processor of FingerTip uses a potent 32-bit ARM Cortex M3 core, which can detect, classify, and monitor up to ten simultaneous finger touches while also offering a high level of overall touch performance in noise rejection and response speed.
Both synchronous and asynchronous display operations are supported by ST’s FingerTip FTG2-SLP controller. As the refresh rate fluctuates, OEMs are able to maintain fluid user interactions thanks to this. The controller is particularly perfect for smartphones with flexible AMOLED displays since they embed the touch-sensitive panel right onto the OLED emitter layer for a remarkably tiny profile.
To ensure flawless touch detection, the chip’s analogue front end (AFE) makes use of a differential architecture and several scanning techniques. High signal-to-noise ratio is provided by the internal design, which also guarantees very low intrinsic noise. Even when operating at the fastest refresh rate permitted by the display, the 480Hz report rate catches each touch event.
