Under Display Touch ID
Touch ID under the display has been rumored for several years, even before the iPhone X launch. Hopes were high that the technology would debut in the iPhone 12, but it never came to fruition. According to a prolific Apple leaker @L0vetodream, Apple is continuing to work on this technology.
In July of this year, two patent applications detailed ways of dealing with fingerprint reading through a display matrix. These hint Apple is refining this technology. The latest prediction by TF Securities and well-known Apple analyst Ming-Chi Kuo says that Apple may be looking at the iPhone 13 now for this screen-wide Touch ID tech.
