Obviously, Apple is also working hard, hoping to remove the bangs on the iPhone. After all, it really affects beauty. In a patent application named “Sensing System for Detecting Light Received by the Light-emitting Layer of Electronic Device Display Screens” published on March 4, Apple listed a system that embeds the light detection layer into the display stack.
The light sensors related to the light-sensing system can be distributed around or inside the active display area of the display screen. The patent gives two direct examples, claiming that the light sensor can combine the object image of the touch screen, which can be used for the Touch ID in the screen based on the optical imaging system.

The patent also believes that the iPhone’s ambient light sensor can also be included. More specifically, the system itself can include photodiodes or solar cell arrays integrated between pixel areas or around the light-emitting display.
The system can use electrical signals from photodiodes or solar cells to sensing colors or the intensity of light incident on the display stack. Most of the description of this patent focuses on the ambient light sensor.
Even if it is only used for the ambient light sensor, the system can also be used to reduce the size of the bangs of future iPhone models, because the light sensor is currently embedded in the bangs.
However, in light of rumors that Apple is seeking to minimize bangs or re-introduce Touch ID on future phones, the patent application is likely to be part of an increasing number of technologies that may achieve this goal. There has been a lot of news before that Apple is building a mobile phone with under-screen fingerprints.
