The embodiment of the invention discloses a screen state control method, device, storage medium and mobile terminal. The method includes: in a strong light environment, determining the ratio of the proximity sensor characteristic curve to the ideal curve in each set interval; obtaining the strength value of the receiving end signal corresponding to the proximity sensor transmitter being in the on state and the off state, and according to the ratio The intensity values are respectively compensated; the corrected proximity value of the proximity sensor is determined according to the compensated intensity value, and the screen is turned off or on according to a comparison result of the corrected proximity value and a set threshold. The embodiment of the present invention adopts the above-mentioned technical solution, which can effectively prevent the situation that the screen does not turn off when a human face or ear is close to the screen.
Description
technical field [0001] Embodiments of the present invention relate to mobile terminal technology, and in particular to a screen state control method, device, storage medium and mobile terminal. 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 proximity sensor...
