S3930 Touch Controller

The Synaptics S3930 series is a next-generation touch controller designed specifically for foldable OLED and ultra-thin mobile displays. As form factors evolve and panel technologies advance, the S3930 meets the growing demand for high-performance, low-latency touch in challenging environments—where display noise, thin stack-ups, and dynamic bending are common. At the core of the S3930 are innovations that dramatically improve noise mitigation by isolating touch signals through advanced filtering. A key enabler is Synaptics’ patented multi-frequency-region parallel sensing (MFRPS), which reduces sensing bursts across large sensors using continuous-time acquisition and a digital analog front-end (dAFE). This architecture enables faster, more efficient multi-frequency decoding while lowering system cost. Combined with a compact 5.1 × 6.8 mm footprint, a powerful RISC-V™ + Hydra vector engine, and support for large OLED panels, the S3930 enables ultra-responsive, reliable touch across premium smartphones, tablets, and next-gen foldables
