METHOD AND APPARATUS FOR DETECTING AMBIENT LIGHT UNDER DISPLAY SCREEN, AND ELECTRONIC DEVICE

The present application provides a method, apparatus, and electronic device for detecting ambient light under a display screen, which could reduce the influence of a light leak from a screen on detection of the ambient light. The method includes: generating (110) an interval identification signal for screen light of the display screen according to a dimming period of the display screen, the interval identification signal being used to identify the screen light that is within a specific time interval in the dimming period; performing (120) data collection according to a sampling signal; reading (130) data of a target sampling period from data of a plurality of sampling periods of the sampling signal according to the interval identification signal, the target sampling period being a sampling period in which sampling time overlaps with the specific time interval in time; and detecting (140) the ambient light according to the data of the target sampling period.
