Abstract

The embodiment of the invention discloses a screen state control method, a device, storage medium and a mobile terminal. The method comprises the following steps: determining a rate of a characteristic curve of a proximity sensor to an ideal curve in each set interval under the high light environment; acquiring an intensity value of a corresponding receiving end signal when a transmitting end of the proximity sensor is in each of the turn-on state or the turn-off state, and respectively compensating the intensity value according to the rate; determining a corrected approximation of the proximity sensor according to the compensated intensity value, and controlling the screen to be in the screen-extinguishing state or the screen-brightening state according to a comparison result of the corrected approximation and a set threshold. By adopting above mentioned technical scheme, the control method disclosed by the embodiment of the invention can effectively prevent the situation that the screen is unextinguished when the human face or the human ear closes 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...
