At least one pair of first electrodes 112 for providing an electric field to the conductive thin film 111 under the control of the applied first voltage signal; the second electrode 113 is used for collecting a second voltage signal at a corresponding position when a user touches the conductive film 111; and the detection module is connected with the plurality of second electrodes 113 and is used for detecting the touch position of the user on the conductive film 111 according to the second voltage signals collected by the plurality of second electrodes 113.
Referring to fig. 2, a schematic diagram of voltage distribution at various places on the conductive film when a user does not touch the conductive film according to an embodiment of the present invention is shown, and fig. 3 is a schematic diagram of voltage distribution at various places on the conductive film when a user touches the conductive film according to an embodiment of the present invention.
As shown in fig. 2, four first electrodes 112 are disposed around the conductive film 111, two first electrodes 112 facing each other form a pair of first electrodes, for example, two first electrodes 112 on the left and right sides form a pair of first electrodes, and two first electrodes 112 on the upper and lower sides form another pair of first electrodes.
If the first voltage signal is applied to the two first electrodes 112 on the upper and lower sides, the first voltage signal is not applied to the two first electrodes 112 on the left and right sides, the voltage value of the first voltage signal applied to the second electrode 112 on the upper side is 0V, and the voltage value of the first voltage signal applied to the second electrode 112 on the lower side is 7V, an electric field is formed on the conductive film 111 between the two first electrodes 112 on the upper and lower sides, and when the conductive film 111 is not touched by a user, the voltage value of the conductive film 111 is 5.1Vpp at the positions of the two first electrodes 112 on the left and right sides, the voltage value of the conductive film 111 is 2.3Vpp at the positions of the upper left and right corners of the conductive film 111, and the voltage value of the conductive film 111 is 1.7Vpp at the position of the first electrode 112 on the upper side.
When the finger F of the user touches the conductive film 111, since the human body acts as a conductor, a small amount of current at the touch position is conducted to the ground GND by the human body, so that the voltage value at the touch position is lowered.
As shown in fig. 3, the position touched by the finger F of the user is close to the upper first electrode 112 on the upper side and the upper right corner of the conductive film 111, and therefore, the voltage values of the conductive film 111 at these two positions decrease, the voltage value of the conductive film 111 decreases to 0.9Vpp at the position of the first electrode 112 on the upper side, and the voltage value of the conductive film 111 decreases to 1.2Vpp at the position of the upper right corner of the conductive film 111.
Referring to fig. 4, a schematic diagram of an electric field distribution on a conductive film of an embodiment of the present invention is shown.
When the first voltage signal is applied to the two first electrodes 112 on the upper and lower sides and the first voltage signal is also applied to the two first electrodes 112 on the left and right sides, an electric field as shown in fig. 4 is formed on the conductive film 111, when the finger F of the user touches the conductive film 111, the voltage value at the touched position is lowered, and the touched position of the user is determined by detecting the position where the voltage value is lowered.
It should be noted that fig. 2 to 4 only show the case that four first electrodes 112 are disposed around the conductive film 111, and it is understood that the number of the first electrodes 112 disposed around the conductive film 111 according to the embodiment of the present invention is not limited thereto, and may be an even number greater than or equal to 2, and of course, other numbers of the first electrodes 112 may be disposed, such as 4 pairs of the first electrodes 112; in addition, the position of the first electrode 112 is not limited to that shown in fig. 2 to 4.
In the embodiment of the present invention, since the voltage value at the touch position is decreased when the finger of the user touches the conductive film 111, the second voltage signals at various positions on the conductive film 111 need to be collected to determine the position of the decreased voltage value, and therefore, a plurality of second electrodes 113 need to be disposed on the side of the designated area 11 away from the conductive film 111.
Each second electrode 113 is connected with the conductive film 111 at the corresponding position through a wire, when a finger of a user moves in a formed electric field, a voltage value of the conductive film 111 at the touch position is changed, second voltage signals at the corresponding position are collected through the plurality of second electrodes 113, the plurality of second electrodes 113 are all connected with the detection module, the detection module performs signal processing on the second voltage signals collected by the plurality of second electrodes 113, the touch position of the user on the conductive film 111 is detected, and therefore gesture recognition and motion tracking are achieved.
When the number of the second electrodes 113 provided in the mobile terminal is greater, the more the second voltage signals are collected, the more accurate the detected touch position of the user is.
In one embodiment of the invention, the detection module comprises a control chip; and the control chip is used for acquiring voltage values of the second voltage signals acquired by the plurality of second electrodes 113 and determining the touch position of the user on the conductive film 111 according to the voltage values.
In another embodiment of the present invention, the detection module includes an electrode receiver and a control chip; the electrode receiver is respectively connected with the second electrodes 113 and the control chip, and is used for reading voltage values of the second voltage signals acquired by the second electrodes 113 and sending the voltage values to the control chip; and the control chip is used for determining the touch position of the user on the conductive film 111 according to the voltage value sent by the electrode receiver.
The second voltage signal acquired by the second electrode 113 is an analog signal, and the second voltage signal needs to be converted into a digital signal to obtain a voltage value of the second voltage signal, preset voltage values of the plurality of second electrodes 113 are stored in the mobile terminal, where the preset voltage values are voltage values of third voltage signals at corresponding positions acquired by the plurality of second electrodes 113 when the user does not touch the conductive film 111, and the touch position of the user on the conductive film 111 is determined according to a difference value between the voltage values of the plurality of second voltage signals and the corresponding preset voltage values.
The second voltage signal can be directly converted into a digital signal through the control chip, and a functional unit for converting an analog signal into the digital signal is integrated in the control chip; the second voltage signal can be converted into a Digital signal through a separate electrode receiver, the electrode receiver can be an ADC (Analog-to-Digital Converter), and in this case, a functional unit for converting an Analog signal into a Digital signal does not need to be integrated inside the control chip.

Certainly, the conductive film 111 may also be manufactured on the planar area of the mobile terminal by using a nano conductive material, and the existing ITO is replaced by at least one pair of the first electrodes 112 and the plurality of second electrodes 113 around the conductive film 111 to realize a touch function.

When the mobile phone is put on a horizontal position for self-shooting, one hand of a user needs to hold the mobile phone, if touch operation can be only carried out in a display area, when an image acquired by the camera needs to be amplified, the other hand needs to be used for sliding from the middle to the outside, and when the image acquired by the camera needs to be amplified, the other hand needs to be used for sliding from the outside to the inside; however, when the back cover of the mobile phone can also realize the touch function, when a user holds the mobile phone with one hand, two fingers of the hand can slide on the back cover to realize the enlargement and reduction of the image, the operation can be finished without using two hands, and the operation of the user is simplified.

It should be noted that one or more second electrodes may be designated, and when one second electrode is designated, it indicates that the user performs single-point touch on the conductive film 111, and when a plurality of second electrodes are designated, it indicates that the user performs multi-point touch on the conductive film 111.
