Proximity sensor control method and apparatus, storage medium and mobile terminal

Abstract

Embodiments of the invention disclose a proximity sensor control method and apparatus, a storage medium and a mobile terminal. The method comprises the steps of outputting driving signals of a preset time sequence and a duty ratio to a transmitting end and a receiving end of a proximity sensor, controlling the transmitting end to periodically enter a sleep mode, a disable mode and an enable mode, and controlling the receiving end to periodically enter the sleep mode and a sampling mode; in a sampling interval of the receiving end corresponding to the disable mode, controlling an analog-digital converter in the receiving end to store a first input signal; and in a sampling interval of the receiving end corresponding to the enable mode, controlling the analog-digital converter to remove the first input signal from a received second input signal and output a first intensity value corresponding to the second input signal after the removal processing. By adopting the technical scheme, the problem that a screen is not turned off when a person is close to the screen under strong light can be avoided; and meanwhile, the problem of screen flashing in a lamp box environment can be avoided and a normal screen turn-on and turn-off function is realized.

Description

technical field [0001] Embodiments of the present invention relate to mobile terminal technologies, and in particular, to a method, device, storage medium and mobile terminal for controlling a proximity sensor. Background technique [0002] With the continuous development of smart phones in the direction of thinner and lighter, the volume of mobile phone components also needs to be smaller and smaller. To meet this requirement, 3-in-1 sensors incorporating a proximity sensor, an ambient light sensor, and an infrared (IR) emitting light-emitting diode (LED) are widely used in smartphones. [0003] At present, a smart phone monitors the intensity of ambient light through an ambient light sensor (ALS) to automatically adjust the brightness of a liquid crystal display (LCD) backlight, or to control the lighting of button lights on and off. Proximity sensor (Proximity sensor, PS) and infrared emitting LED, wherein, the infrared emitting LED is used as the transmitting end of the...

Problems solved by technology

Therefore, in a strong light environment, the proximity value will become smaller. At this time, even if the smartphone is close to the face, it is still impossible to control the screen from turning off.

For another example, in the light box environment, the measured proximity value fluctuates due to the infrared interference of the fluorescent lamp, so that the mobile terminal cannot accurately control the lighting or extinguishing of the screen according to the actual distance between the face or the human ear and the screen.
