Apple is researching an ambient light sensor that could be embedded underneath an iPhone display, a development that could aid in removing or reducing the screen notch.
Current Apple smartphones, such as the iPhone 11, contain an ambient light monitor in their notch or top bezel. But a new patent application details a way that Apple could embed a light sensor underneath a display, likely bringing it one step closer to nixing the notch altogether.
In its patent application, Apple notes that light sensor placement can be challenging. "If care is not taken, an ambient light sensor may consume more space in an electronic device than desired. In some arrangements, there may be challenges associated with operating an ambient light sensor accurately due to potential interference from other components.
For example, an ambient light sensor installed underneath display pixels would pick up additional light information from the pixels themselves, throwing off the reading. But Apple notes that an array of pixels installed over an ambient light sensor could be controlled while the sensor was gathering measurements.
"For example, the control circuitry may modulate the brightness of image frames being displayed by the array of pixels. In an illustrative arrangement, image frame brightness levels are modulated in a repeating sequence. During the repeating sequence, the image frame brightness levels may, for example, be repeatedly changed between multiple different levels," the patent reads.
