The U.S. Patent and Trademark ****** today granted Apple a patent that describes a display capable of reading a user's fingerprint without a dedicated Touch ID (https://www.macrumors.com/roundup/touch-id/) sensor (via AppleInsider (http://appleinsider.com/articles/17/02/14/apple-patents-screen-tech-capable-of-reading-fingerprints-without-dedicated-sensor)). The patent is interesting given current rumors swirling around the iPhone 8 (https://www.macrumors.com/roundup/iphone-8/), which is expected to do away with the home button and integrate Touch ID directly into the display, but perhaps more **teworthy is the patent IP's re-assignment from LuxVue, a little-k**wn company acquired by Apple in 2014 (https://www.macrumors.com/2014/05/02/apple-acquires-luxvue/) that developed low-power microLED-based displays.

Titled "Interactive display panel with IR diodes (http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=2288&f=G&l=50&d=PTXT&s1=(1%2F1.CCLS.+AND+20170214.PD.)&p=46&OS=ccl/1/1+and+isd/2/14/2017&RS=(CCL/1/1+AND+ISD/20170214))", the patent details a touch display that uses specifically microLED-sensing tech**logy, rather than the traditional active matrix hardware utilized by most consumer smartphones and tablets.
The tech**logy replaces larger capacitive sensors with smaller infrared light emitters and sensors, which sit alongside the RGB LED display substrate or on a microchip mounted to the substrate. These "interactive pixel" formations can then be calibrated to perform any number of functions, including ambient light sensing, proximity detection, and **tably complex touch detection, which works by bouncing infrared light off a user's finger and back to the sensing diodes.
In the latter operation, specific rows ? or a whole portion of the display ? scan for a user's finger, which generates a proximate positioning bitmap to inform the system of the target's location and immediate surround. Bitmaps can include data like the intensity of incoming light, enabling a deeper analysis of the object and its surface curvature ? dark and bright spots corresponding to the ridges and grooves of a fingerprint, for example.

The patent describes a couple of embodiments for the tech**logy, including a microLED display with a higher density of interactive pixels in certain areas of the screen, such as where a virtual home button may be located. Alternatively, said pixels may ramify throughout the display in sufficient number as to make fingerprint identification on any portion of the screen a possibility.
Apple has explored other systems (https://www.macrumors.com/2016/10/04/new-apple-patent-touch-id/) for enhancing display fingerprint recognition in the past (https://www.macrumors.com/2013/11/25/apples-plans-to-enhance-touch-id-with-trackpad-capabilities-and-display-integration-revealed/). As with all patents though, the standard qualification applies: Apple may deem the LuxVue invention surplus to its upcoming product requirements. However, on its own, the system goes to show that reliable fingerprint identification does **t necessarily rest on Touch ID alone. With rumors suggesting Apple may incorporate iris scanning (https://www.macrumors.com/2017/02/10/iphone-8-iris-scanner-digitimes-rumor/) into the iPhone 8, the security implications of dropping Touch ID's focused capacitive drive ring altogether may **t be so great after all.
