As the foldable device market rapidly grows, Synaptics has expanded its technology leadership in the rapidly expanding foldable market by introducing a new, ultra-small, high-performance touch controller.

Synaptics announced on the 15th that it has announced a new touch controller S3930 series.

Designed to address the technological challenges of the foldable device market, this ultra-compact, high-performance product boasts significantly improved responsiveness, energy efficiency, and accuracy.

The foldable display market is rapidly expanding, growing at an average annual rate of 42%.

On the other hand, high parasitic capacitance, display noise, and short sensing time are pointed out as problems for ultra-thin OLED panels. As displays become thinner, touch detection performance may deteriorate.

“The S3930 series addresses these challenges with advanced sensing and filtering technologies,” said Sam Toba, director of product marketing at Synaptics. “It will provide customers with a smoother, faster touch experience and will contribute to future device designs.”

The core technology of the S3930 series is ‘Multi-Frequency-Region Parallel Sensing (MFRPS)’.

This reduces the number of sensing bursts in large touch sensors and enables efficient multi-frequency decoding by utilizing the continuous sensing function.

This effectively reduces noise while improving touch accuracy and response speed.

Additionally, the S3930 is equipped with a high-performance processor to process complex algorithms more effectively.

It combines Si-Five's latest E7 MCU core with Synaptics' proprietary Hydra vector processor for enhanced noise reduction and anti-touch capabilities.

In particular, the Hydra vector processor is designed to improve the computational speed of machine learning algorithms.

The S3930 series supports LTPO and polarizer-less structures while implementing an ultra-thin bezel.

With a size of just 5.1×6.8mm, the device can be made thinner and lighter, and it maintains consistent touch performance even in dynamic environments where it is folded or unfolded.

The space-saving design also allows hardware developers to consider a variety of factors, such as installing larger batteries.
