AI Technical Summary
Ambient light sensors on mobile devices require a specific field of view, limiting the display area and affecting user experience by preventing parts of the screen from being used for display, and the placement of optical proximity sensors and front-facing cameras reduces the screen-to-body ratio.
Replace ambient light sensors with optical proximity sensors and position them similarly to ambient light sensors under the display screen, using optical signals to avoid interference and enable display in the sensor area, allowing both types of sensors to be co-located.
Maintains display effectiveness by enabling the sensor area to show pictures, preserving the screen-to-body ratio, and improving user experience by minimizing visual impact from sensor operations.
