In a technical patent approved by Apple, the screen's technical details to detect light are shown. This technology patent may help Apple integrate the Touch ID fingerprint sensor and Face ID facial recognition sensor into the bottom of the screen, thereby eliminating the notch area in the current iPhone models.
In the technical patent titled "Sensing system for detecting light received by the luminescent layer of electronic device display screens," in short, Apple plans to embed a light detection sensor under the display screen, which can be used for Face ID and Touch ID.
The company shared two potential implementation details of the technology. In the first case, the light sensor behind the display screen can combine images of objects touching the screen. This hints at the return of Touch ID. Also, the Apple patent mentions the use of ambient light sensors for operation. The second embodiment will use photodiodes or solar cell arrays to assemble the pixels of the image. The system will also accumulate electrical signals from photodiodes to sense the intensity and color of light. The second implementation method points to Face ID, which may appear in future iPhone iterations.
It should be noted that Apple has applied for many patents, and not all patents may be commercially available. However, the patent does let people see the company's future prospects and the potential introduction of the technology.
