Flexing the Future of Foldable OLEDs
Flexing the Future of Foldable OLEDs
As foldable devices gradually enter the mainstream market, display and touch technologies are facing increasing demands for tighter integration and lower power consumption. From flexible materials to ultra-narrow bezel designs, every advancement plays a pivotal role in shaping the next wave of user experience. Particularly when screens are no longer fixed in form, stable and high-performance touch response becomes the key to product differentiation. Combining IoT and AI with Human Interface technologies, Synaptics Inc. recently introduced its groundbreaking S3930 series of touch controllers—an innovative solution specifically designed for foldable displays.
Foldable OLED Unlocks Versatile Application Opportunities
These new screens are large, thin, and flexible, which makes them tricky to work with. The S3930 helps make sure they stay responsive, accurate to the touch, and battery efficient. The S3930 is made for the next wave of foldable phones, which has become a rapidly growing market.
Foldable OLED panels have brought us numerous benefits. They let users carry a larger screen in compact form without a rigid backlight like an LCD, and due to their flexible nature, they are significantly more durable, especially when combined with protective polymers instead of glass. The lack of a backlight or filter also helps reduce the thickness and number of parts, which aids in energy efficiency and superior visual quality, as OLEDs only light up individual pixels when needed.
Of course, with these benefits, OLEDs present multiple challenges as well, such as too much electrical interference, an abundance of background static, and not enough time to pick up touch signals. And these problems only get worse as screens get thinner. The new S3930 chip helps fix these issues by improving how the screen senses touch and filters out noise. This means smoother, more accurate touch for users — and it helps stay ready for the next generation of devices.
Smart Noise Suppression Expands Use Cases and Ensures High-Precision Touch
The S3930 chip has smart technology that helps reduce “noise” — the kind of interference that can interfere with how your screen detects touch. It uses a special method (developed and patented by Synaptics) that makes touch detection more accurate and less power-hungry, especially on big foldable screens.
The S3930 also has a powerful new processor to run complex software that prevents false touches and improves performance. This includes a high-speed main chip and a special helper chip that boosts AI functions, helping your device respond quickly and accurately, even when handling multiple tasks simultaneously.
Compact Packaging Design Inspires the Future of Device Innovation
The S3930 is built to work with the newest types of OLED screens, including ones that bend and don’t need extra layers. It features the smallest 5.1 × 6.8 mm footprint package—about the size of a grain of rice—so it fits easily into thin, lightweight devices. Even when the screen is folding or flexing, it still keeps touch working smoothly. Because it takes up so little space, designers can use the extra room for things like bigger batteries or other features.
