Abstract

The invention provides a proximity detection method and a mobile terminal. The mobile terminal comprises a dust screen. The method comprises the steps of acquiring a target capacitance value of the dust screen; determining a target difference value between the target capacitance value and a reference capacitance value, wherein the reference capacitance value is a capacitance value of the dust screen under a condition in which no object is proximate to the dust screen; and according to a comparison result between the target difference value and a preset threshold value, determining whether an object is proximate to the mobile terminal or not. In this way, the target capacitance value of the dust screen can be acquired, and thus the target difference value between the target capacitance value and the reference capacitance value can be determined; whether the object is proximate to the mobile terminal or not can be determined according to the comparison result between the target difference value and the preset threshold value; and the proximity detection is performed by using the dust screen, so an extra front space of the mobile terminal does not need to be occupied, i.e., a screen-to-body ratio of the mobile terminal is not limited.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an approach detection method and a mobile terminal. Background technique [0002] The mobile terminal can implement the proximity detection function through the infrared proximity sensor. For example, when answering a call, when the infrared proximity sensor in the mobile terminal detects that a human face is close to the screen, the screen can be automatically blacked out. Misoperation can be avoided. [0003] In the prior art, an infrared proximity sensor is disposed on the front of a mobile terminal. Outside the display area of ​​the screen of the mobile terminal, a certain space is required to place the infrared proximity sensor, which limits the screen-to-body ratio of the mobile terminal. Therefore, in the prior art, the infrared proximity sensor will result in a smaller screen-to-body ratio of the mobile terminal. Contents of the invention [0004] Embodiments...
