Abstract
A proximity-detection method, a non-transitory computer readable medium and an electronic device are disclosed. The proximity-detection method is applied to the electronic device. The electronic device may include a display screen and an infrared-light proximity sensor covered by the display screen and configured to detect whether an object is proximity to the electronic device, the display screen has a capability of allowing infrared lights to pass through. The proximity-detection method may include setting an operation timing of the display screen as a target timing when the infrared-light proximity sensor is enabled, wherein the target timing comprises a target duration and the display screen is controlled to emit no lights during the target timing; controlling the infrared-light proximity sensor to emit the infrared lights during the target duration; and performing proximity detection based on the infrared lights.
