VIENNA—Apple supplier AMS has developed a light and infrared proximity sensor that can sit behind a smartphone’s screen, reducing the area required for such sensors and so allowing for a larger display, AMS said on Jan. 7.
AMS provides Apple with optical sensors for 3D facial recognition features on its newest iPhones. Its shares slid by a fifth on Jan. 3 after Apple issued a sales warning, though they have since recovered most of that.
