Synaptics Unveils Next-Generation Touch Controller Engineered for Foldable OLED Displays

Core Insights - Synaptics has launched the S3930 series touch controllers designed for foldable OLED mobile device displays, addressing the unique technical challenges of this rapidly growing market, which is expanding at a 42% CAGR [1][2]. Technology Innovations - The S3930 series incorporates innovations to mitigate challenges such as high background capacitance and extreme display noise, enhancing touch responsiveness and accuracy [2][3]. - Key technology includes multi-frequency-region parallel sensing (MFRPS), which reduces the sensing bursts needed for large touch sensors, making the sensing process more efficient and cost-effective [3]. Processor and Performance - The S3930 features an upgraded processor, the E7 MCU core from Si-Five, and Synaptics' Hydra vector co-processor, enabling effective handling of complex algorithms for noise removal and mistouch mitigation [4]. - The Hydra vector co-processor is specifically designed to accelerate machine learning algorithms that require extensive matrix arithmetic [4]. Design and Optimization - The design of the S3930 supports larger OLED panels, including LTPO and polarizer-less options, while allowing for ultra-narrow bezels, contributing to thinner and lighter devices [5]. - The S3930 has a compact footprint of 5.1 × 6.8 mm, providing more space for additional features like larger batteries in device designs [5]. Availability and Market Impact - The S3930 series is currently in the sampling phase, with mass production expected to begin in July 2025, and multiple OEMs and LCMs are evaluating it for next-generation devices [6].
