Apple working on ‘enhanced’ under-display Touch ID system

A newly-published patent application has claimed that Apple is working on underdisplay fingerprint scanning technology with the aim to bring Touch ID back to the iphone. As per Patently Apple, the patent was filed in the US Patent and Trademark Office, and is titled “Under-display fingerprint sensing based on off-axis angular light” and explains how an underdisplay fingerprint scanner can be made more accurate and reliable. Apple describes its technology as an “enhanced under-display fingerprint sensing” system that uses “off-axis angular light” to read fingerprints more effectively without increasing the size of the components. This method can improve the contrast of fingerprint impressions and maintain the compactness of the entire sensing system. Apple iphone 13 models expected to be launched later this year would “likely” feature a fingerprint scanner embedded under the display for authentication, in addition to Face ID.
