Apple is working on an ambient light sensor that can be embedded under the iPhone display, a development that could help eliminate or reduce the area of the bangs. Current apple smartphones, such as the iPhone 11, include an ambient light display in its bangs or top border. But a new patent application details a way in which Apple can embed a light sensor under the display, possibly one step closer to completely eliminating bangs. < / P > < p > in its patent application, apple pointed out that the location of light sensors could be challenging and that if not careful, ambient light sensors could take up more space than expected in electronic devices. In some arrangements, accurate operation of ambient light sensors may be challenging due to potential interference from other components. For example, the ambient light sensor installed below the display pixel will receive additional light information from the pixel itself, thus unable to read accurately. But Apple points out that the pixel array mounted above the ambient light sensor can be controlled as the sensor collects measurements. For example, the control circuit may modulate the brightness of the image frame displayed by the pixel array. In an illustrative arrangement, the image frame luminance level is modulated in a repeated sequence. In the repeated sequence, the brightness level of the image frame may be changed repeatedly among a plurality of different levels, for example. By modulating the brightness of a particular image frame, the stray light intensity from the display itself can be modulated. The system can then detect which stray light is modulated, remove their contribution to ambient light measurement and produce more accurate readings. As a result, the ambient light sensor under the display can play a better role, such as automatically changing the brightness of the display screen or adjusting the color temperature. Apple points out that the system can also be used for other purposes, such as adjusting compensation for display degradation (such as dead pixels) measured by sensors. The patent application was first filed in March 2019 and granted on September 17, 2020, listing Po Chieh hung, prashanth s. holenarsipur and serhan o. isikman as inventors. All three have been involved in Apple patents in the past, including patents related to the color sampling Apple pencil model; optical sensors; and an adjustable Apple watch strap. < / P > < p > there are rumors that apple is working to eliminate or reduce the bangs on its flagship smartphones by using sensors and cameras under the display. However, there is no definite timetable for when all this will come true. Global Tech
