Title:
PROXIMITY-DETECTION METHOD FOR ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/174341
Kind Code:
A1
Abstract:
A proximity-detection method is applied to an electronic device. The electronic device may include a display screen(40) and an infrared-light proximity sensor (50)covered by the display screen (40) and configured to detect whether an object (70) is proximity to the electronic device, the display screen (40) has a capability of allowing infrared lights to pass through. The proximity-detection method may include setting an operation timing of the display screen (40) as a target timing when the infrared-light proximity sensor (50) is enabled, wherein the target timing comprises a target duration and the display screen (40) is controlled to emit no lights during the target timing, controlling the infrared-light proximity sensor (50) to emit the infrared lights during the target duration, and performing proximity detection based on the infrared lights. A non-transitory computer readable medium and an electronic device are also provided.
