From Forbes: Picked up by PatentlyApple, Apple has just won a patent which explains how its existing optical fingerprint reader technology (already used in the new 16-inch MacBook Pro) can tweaked to operate under a display. In fact, Apple is pretty blunt about this writing in the patent:
“An optical image sensor is carried by the housing under the display. The optical image sensor senses biometric image data associated with a user, such as, for example, data representative of a biometric image of the fingerprint patterns of the user’s finger. The controller may perform an authentication function by matching the acquired biometric image data to the stored biometric template data stored in the memory.”
Apple also illustrates the patent using a smartphone form factor.
