SI provides comprehensive semiconductor solutions for laptops, covering 3D sensing, optical sensing, imaging, audio, and haptic applications. The front-facing system integrates a 3D iToF image sensor to enable facial recognition and 3D sensing, while ambient light, proximity, and multi-function optical sensors support automatic screen brightness adjustment and proximity sensing. Multispectral and single-point dToF sensors further enhance imaging performance. A smart audio amplifier and audio codec deliver high-quality audio for video conferencing, media playback, and other audio applications, while a haptic linear motor enables precise tactile feedback through the touchpad.
