Apple is working on an ambient light sensor that can be embedded under the iPhone display to help eliminate or reduce screen bangs.
Current Apple smartphones, such as the iPhone 11, include an ambient light sensor in their bangs or top bezel. But a new patent application from Apple details a method to embed a light sensor under the display, making it one step closer to eliminating bangs completely.
In its patent application, Apple pointed out that the location of the light sensor may be challenging . For example, an ambient light sensor installed under the display pixels will receive additional light information from the pixels themselves, which can interfere with readings. But Apple pointed out that the pixel array installed above the ambient light sensor can be controlled while the sensor collects measurements.
By modulating the brightness of a particular image frame, the intensity of stray light from the display itself can be modulated . The system can then detect which stray light is modulated, remove their influence on the ambient light measurement, and produce more accurate readings.
In this way, the ambient light sensor under the display screen can play its role better, such as automatically changing the brightness of the display screen or adjusting the color temperature.
Apple pointed out that the system can also be used for other purposes, such as adjusting and compensating for display degradation (such as dead pixels) measured by the sensor.
Naijatechnews learned that the patent application was first filed in March 2019 and was authorized on September 17, 2020. Po-Chieh Hung, Prashanth S. Holenarsipur and Serhan O. Isikman are the inventors. All three of them have worked in the past. Participated in Apple patents.
There are rumors that Apple is working to eliminate or reduce bangs on flagship smartphones by using sensors and cameras under the display. However, there is no definite timetable when this will be achieved.
