Patent information that can be connected to display-embedded Touch ID
The patent published by the USPTO on November 3, 2020, local time, is entitled “Shortwave Infrared Optical Imaging in Electronic Device Display” and describes how to perform fingerprint recognition through the display.
In fingerprint recognition by this method, an optical imaging system is mounted under the display, then short-wave infrared rays are emitted toward the display, and the reflected light corresponding to the unevenness of the finger in contact with the display is read to recognize the fingerprint. ..
Since infrared rays are invisible to the human eye, AppleInsider evaluates it as a rational system without feeling dazzling with the irradiation light even during fingerprint recognition using this method.
The system applied by Apple is planned to provide a minute light guide path between the pixels of the display so that infrared light and reflected light emitted from the optical imaging sensor placed under the display can pass through.
Is it unlikely that it will be installed soon?
Due to the effects of the new coronavirus infection, there are more opportunities to wear masks on a daily basis, so Touch ID is easier to use than Face ID, but this patent is still in the development stage. , It has been pointed out that it is unlikely that it will be installed in the 2021 model iPhone 13, so even if a display-embedded Touch ID appears, it will take time.
