According to an exemplary embodiment of the present disclosure, as shown in fig. 1, an electronic device is provided in this embodiment, where a display screen of the electronic device is foldable, and the electronic device may be, for example, a smart phone, a tablet computer, an electronic reader, a wearable device, and so on. The electronic device comprises a first folding screen 1 and a second folding screen 2 which are connected in a folding way, the size of a display area of the electronic device can be adjusted according to the folding angles of the first folding screen 1 and the second folding screen 2, for example, when the folding angles of the first folding screen 1 and the second folding screen 2 are 0 degree, the function of single-screen display of the first folding screen 1 or the second folding screen 2 can be started; when the folding angle of the first folding screen 1 and the second folding screen 2 is 180 degrees, the function of double-screen display of the first folding screen 1 and the second folding screen 2 can be started. When in use, a user can reasonably adjust the folding angles of the first folding screen 1 and the second folding screen 2 according to the display requirement of the user on the screen so as to adjust the size of the display area. Therefore, it is necessary to detect the folding angles of the first folding screen 1 and the second folding screen 2 to determine whether the electronic apparatus turns on the single-screen display function or the double-screen display function.
The electronic device of the present embodiment further includes a first capacitive plate 11 and a second capacitive plate 21, as shown in fig. 1, the first capacitive plate 11 is disposed on the first folding screen 1, and the second capacitive plate 21 is disposed on the second folding screen 2. When a constant voltage is applied to the first capacitive plate 11 and the second capacitive plate 21, a constant electric field is generated between the first capacitive plate 11 and the second capacitive plate 21, and the electric field strength does not change with time, and the magnitude of the electric field strength is not easily disturbed by the outside. In the present embodiment, the manner of applying the constant voltage between the first capacitive plate 11 and the second capacitive plate 21 is not limited. In an example, referring to fig. 1, the first and second capacitive plates 11 and 21 are supplied with power by providing independent power supply units 22 such that a constant voltage is generated between the first and second capacitive plates 11 and 21. In another example (this example is not shown in the figures) the first capacitive plate 11 is powered by the first folding screen 1 and the second folding screen 2 powers the second capacitive plate 21 such that a constant voltage is generated between the first capacitive plate 11 and the second capacitive plate 21.
The electronic device further includes an electric field detection unit 12, as shown in fig. 1, the electric field detection unit 12 is disposed on the first capacitive plate 11 and located between the first capacitive plate 11 and the second capacitive plate 21, the electric field detection unit 12 detects an electric field intensity between the first capacitive plate 11 and the second capacitive plate 21, and the electric field detection unit 12 outputs an electric signal corresponding to the electric field intensity, where the electric signal may be a current signal or a voltage signal. The structure of the battery detection unit 12 is not limited in this embodiment, and the electric field detection unit 12 may be, for example, a MEMS electric field sensor, which is small in size, light in weight, and low in power consumption. The present embodiment is not limited to the arrangement position of the electric field detection unit 12 on the first capacitive plate 11, for example, the electric field detection unit 12 is arranged at the center position of the first capacitive plate 11 so that electric field intensity detection can be performed better.
The electronic device further includes a signal determining unit 13, as shown in fig. 1, the signal determining unit 13 being electrically connected to the electric field detecting unit 12, the signal determining unit 13 receiving the electric signal output from the electric field detecting unit 12 and determining the magnitude of the received electric signal. When the electric field strength detecting unit 12 outputs a current signal, the signal determining unit 13 is a current signal determining unit, and determines the magnitude of the current signal; when the electric field strength detecting unit 12 outputs a voltage signal, the signal determining unit 13 is a voltage signal determining unit, and determines the magnitude of the voltage signal. The present embodiment is not limited to the setting position of the signal determining unit 13, for example, the signal determining unit 13 is set on the first folding screen 1 and is located on the side of the first capacitive plate 11 away from the second capacitive plate 21, so as to reduce the wiring length, shorten the propagation path of the electric signal output by the electric field detecting unit 12, and improve the angle detecting efficiency.
The electronic device further comprises an angle determining unit (not shown in the figures) which is in signal connection with the signal determining unit 13. The signal connection between the angle determining unit and the signal determining unit may be an electrical connection or a communication connection. The angle determining unit is pre-stored with a constant voltage value U between the first capacitor plate and the second capacitor plate, a mapping relation between the intensity of an electric field and the intensity of an electric signal, and a mapping relation between the distance d between the first capacitor plate and the second capacitor plate and the folding angle. The angle determining unit receives the magnitude of the electric signal sent by the signal determining unit 13, and then determines the magnitude of the electric field strength E corresponding to the electric signal according to a pre-stored mapping relationship between the magnitude of the electric field strength and the magnitude of the electric signal. The distance d between the first capacitive plate 11 and the second capacitive plate 21 can be determined by combining a pre-stored constant voltage value U between the first capacitive plate and the second capacitive plate and combining the formula e=u/d. When the first folding screen 1 and the second folding screen 2 are at different folding angles, the distances d between the first capacitive plate 11 and the second capacitive plate 21 are different, and the folding angles of the first folding screen 1 and the second folding screen 2 can be determined according to the mapping relationship between the distances d and the folding angles stored in the angle determining unit in advance.

Since the magnitude of the electric field strength between the first capacitive plate 11 and the second capacitive plate 21 is related to the distance d between the first capacitive plate 11 and the second capacitive plate 21, the larger the distance d between the first capacitive plate 11 and the second capacitive plate 21 is, the smaller the electric field strength is, the less easily detected, and therefore, in order to ensure the accuracy of the detection of the electric field strength between the first capacitive plate 11 and the second capacitive plate 21, by disposing both the first capacitive plate 11 and the second capacitive plate 21 close to the folded edge 3, the electric field strength between the first capacitive plate 11 and the second capacitive plate 21 is always at the magnitude of the electric field strength easily detected, regardless of the unfolded state or the folded state.
