According to the different material of the thin film, Indium Tin Oxide (ITO) thin film, antimony oxide (ATO) thin film, cadmium oxide (CTO) thin film, etc. may be included, and the specific material type of the thin film electrode is not limited in this embodiment.
In the structure of fig. 1, 103 is a main board of the mobile terminal, 104 is a rear cover of the mobile terminal, 105 is a battery, and 106 is a main upper board and a screen module of the mobile terminal.
In the embodiment of the invention, the two film electrodes are oppositely arranged in the mobile terminal, so that the two film electrodes form a three-dimensional capacitance detection structure in the mobile terminal. After the electrode pin is configured for the film electrode and connected to the ADC port of the analog-to-digital converter, the voltage change on the film electrode can be detected, and whether foreign matters enter the mobile terminal or not can be determined through the voltage change.
In an embodiment of the present invention, the thin film electrode may include two thin film electrodes, i.e., a first thin film electrode and a second thin film electrode. When the first film electrode is arranged on the inner wall of the rear cover of the mobile terminal, the second film electrode can be arranged on the inner wall of the display module of the mobile terminal; on the contrary, when the first thin film electrode is disposed on the inner wall of the display module of the mobile terminal, the second thin film electrode may be disposed on the inner wall of the rear cover of the mobile terminal, which is not limited in this embodiment.
As shown in fig. 1, the first thin film electrode 101 may be provided on an inner wall of the rear cover 104 of the mobile terminal. If the mobile terminal is a mobile phone, the first film electrode and the rear cover of the mobile phone battery can be attached together.
Fig. 2 is a schematic diagram of another foreign object detection structure according to an embodiment of the present invention.

Specifically, if a voltage difference is generated, a foreign object can be considered to enter the capacitance detection structure, and the specific position of the foreign object inside the mobile terminal can be determined by acquiring the position of the electrode generating the voltage difference and then according to the position of the electrode.
In the embodiment of the invention, a calculation formula C ═ S/4 pi kd according to the capacitance is shown, wherein the dielectric constant of the medium is shown, S is the facing area of the capacitor plates, d is the distance between the capacitor plates, and k is the constant of the electrostatic force. Because S, d and k are fixed, when the capacitance of the thin film electrode changes, the capacitance of the thin film electrode also changes, according to C ═ Q/U, the capacitance Q on the thin film electrode is fixed, the voltage changes due to the capacitance change, so that a voltage difference is generated, and the voltage difference is converted into a digital signal through an ADC port of the electrode pin.

In the embodiment of the invention, when the earphone or the USB device is inserted, the capacitance of the film electrode is changed. However, the insertion of the headset and USB device can create hardware interrupts. At the moment, the mobile terminal can judge that no foreign matter enters the mobile terminal through hardware interruption, so that prompt information cannot be displayed, and error prompt of a user is avoided.
It should be noted that when the foreign object covers the outside of the mobile terminal or the user holds the surface of the mobile terminal, the dielectric constant of the thin film electrode inside the mobile terminal does not change, at this time, the voltage signal detected through the ADC port does not change, and the mobile terminal does not display the identifier of the foreign object entering on the screen.
In the embodiment of the invention, the foreign matter detection structure is configured in the mobile terminal, and the foreign matter detection structure can comprise at least two electrodes arranged on opposite surfaces of the inner wall of the mobile terminal, electrode pins connected with the electrodes and an ADC port connected with the electrode pins, so that the electrodes can form a capacitance detection structure in the mobile terminal, and whether foreign matters enter the mobile terminal or not can be determined by detecting the voltage difference on the electrodes, thereby solving the problem that a user cannot find the foreign matters entering the mobile terminal in time in the use process of the mobile terminal in the prior art.
