The method includes the following steps:

Step S11: In response to the lighting of the screen, a disconnection instruction is sent to the switch control device, so that the switch control device disconnects the power supply of the infrared transmitter.

The lighting of the screen, that is, the bright screen of the screen, means that the screen is in the bright screen state, the disconnect command is sent to the switch control device, and the switch control device is in the disconnected state. At this time, the infrared transmitter does not work.

In the embodiment of the present invention, a proximity sensor is provided in the mobile terminal. In addition to an infrared transmitter, the proximity sensor also includes an infrared receiver. The infrared receiver is used to receive reflected infrared light for proximity detection. Specifically, the beam axis of the infrared transmitter and the axis of the infrared receiver are on the same plane and form an angle to intersect at an intersection point. When the object approaches the intersection point, the beam line of the infrared transmitter can be emitted to the infrared receiver. So as to achieve the effect of proximity detection. Wherein, the infrared transmitter is arranged at a preset position under the screen of the mobile terminal, for example, it can be arranged at an edge position under the screen. When the mobile terminal is provided with a black screen gesture, the infrared transmitter is in a continuous working state when the mobile terminal is off the screen, so that the mobile terminal can automatically detect whether it is in a pocket and avoid touching the black screen gesture in the pocket by mistake. The switch control device is connected to the communication port of the mobile terminal processor, and the communication port includes a GPIO port.
