The patent details a potential future device that will make use of a bandpass filter. This filter will help isolate which wavelengths of light hit the selfie camera and the Face ID sensor under the phone’s display. So if you’re taking a selfie the filter will let in wavelengths along the visible spectrum for optimal results. And if you need to unlock your phone using Face ID the filter will allow infrared light to pass through instead.
