Optionally, the mobile terminal described in this embodiment of the present application may be mobile or fixed, and if the position of the mobile terminal is fixed, the mobile terminal may also be a terminal device such as a television, a display, and the like, which is not limited in this embodiment of the present application.
Fig. 1 is a schematic structural diagram of a terminal device provided in an embodiment of the present application. The terminal device to which the present application is applied will be specifically described by taking the mobile phone shown in fig. 1 as an example.
Exemplarily, as shown in fig. 1, the electronic device 01 in the embodiment of the present application may be a mobile phone 100. Below is as follows
The mobile phone 100 is an example to specifically describe the embodiment. It should be understood that the cell phone 100 shown in fig. 1 is only one example of the electronic device 01, and that the cell phone 100 may have more or fewer components than shown in the figures, may combine two or more components, or may have a different configuration of components. The various components shown in the figures may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.
In this embodiment, the mobile phone 100 may specifically include: one or more processors 180, radio Frequency (RF) circuitry 110, memory 120, input unit 130, display unit 140 (e.g., a touch screen), one or more sensors 150, audio circuitry 160, wireless fidelity (WiFi) module 170, power system 190, and the like. These components may communicate over one or more communication buses or signal lines. Those skilled in the art will appreciate that the handset configuration shown in fig. 1 is by way of example only and not by way of limitation, that the hardware configuration shown in fig. 1 constitutes a limitation of the handset 100, and that the handset 100 may include more or fewer components than shown, or some components may be combined, or a different arrangement of components may be used.
The various components of the handset 100 are described in detail below with reference to fig. 1.
The processor 180 is a control center of the mobile phone, connects various parts of the entire mobile phone using various interfaces and lines, and performs various functions of the mobile phone 100 and processes data by running or executing an application program stored in the memory 120 and calling data and instructions stored in the memory 320, thereby performing overall monitoring of the mobile phone. Alternatively, processor 180 may include one or more processing units; processor 180 may also integrate an application processor and a modem processor; preferably, the processor 180 may integrate an application processor and a modem processor, wherein the application processor mainly processes an operating system, a user interface, an application program, and the like, and the modem processor mainly processes wireless communication. It will be appreciated that the modem processor described above may not be integrated into the processor 180. For example, the processor 180 may be an kylin 980 chip manufactured by Huanshi technologies, inc. In this embodiment, the processor 180 may include a detection unit for detecting a change in a potential difference between corresponding touch sensitive areas.
Also, the processor 180 may be implemented as an element of another processing unit, and perform the same or similar functions as the processing unit.
In some other embodiments of the present application, the processor 180 may further include an AI chip. The learning and processing capabilities of the AI chip include image understanding capabilities, natural language understanding capabilities, voice recognition capabilities, and the like. The AI chip may enable the handset 100 to have better performance, longer endurance, and better security and privacy. For example, if the mobile phone 100 processes data through the cloud, the result is returned after the data is uploaded, which is very inefficient under the prior art. If the local end of the mobile phone 100 has a strong AI learning capability, the mobile phone 100 does not need to upload data to the cloud, and the data is processed directly at the local end, so that the processing efficiency can be improved, and the security and privacy of the data can be improved.
In the embodiment of the present application, the control unit is equivalent to the processor 180 of the mobile phone, and executes the method for controlling the opening and closing of the screen in the embodiment of the present application.
The RF circuit 110 may be used for receiving and transmitting signals during the transmission and reception of information or a call. In particular, the RF circuit 110 may receive downlink information or downlink data of the base station and then process the downlink information or downlink data for the processor 180; in addition, data related to uplink of the mobile phone is sent to the base station. Typically, the RF circuitry includes, but is not limited to, an antenna, one or more amplifiers, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry 110 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to global system for mobile communication (GSM), general Packet Radio Service (GPRS), code Division Multiple Access (CDMA), wideband Code Division Multiple Access (WCDMA), long Term Evolution (LTE), email, short Message Service (SMS), and the like.
The memory 120 may be used to store applications and data, and the processor 180 executes various functions and data processing of the mobile phone 100 by operating the applications and data stored in the memory 120. The memory 120 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, application programs (such as a sound playing function, an image playing function, etc.) required by one or more functions, and the like; the storage data area may store data (e.g., audio data, a phonebook, etc.) created according to the use of the cellular phone, etc. Further, memory 120 may include high speed random access memory, and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other volatile solid state storage devices, among others. The memory 120 may also store various operating systems such as an IOS operating system, an android operating system, and the like.
The input unit 130 may be used to receive input numeric or character information and generate key signals related to user settings and function control of the cellular phone 100. Specifically, the input unit 130 may include a touch panel 131 and other input devices 132. The touch panel 131, also referred to as a touch display screen, may collect a touch operation performed by a user on or near the touch panel 131 (for example, an operation performed by the user on the touch panel 131 or near the touch panel 131 using any suitable object or accessory such as a finger or a stylus), drive a corresponding connection device according to a preset program, or transmit collected touch information to another device such as the processor 180. Among them, a touch event of the user near the touch panel 131 may be called a hover touch; hover touch may refer to a user not needing to directly touch the touch pad in order to select, move, or drag a target (e.g., an application icon, etc.), but only needing to be located near the cell phone 100 in order to perform a desired function. In the context of a hover touch application, the terms "touch," "contact," and the like do not imply a contact that is used to directly contact the touch display screen, but rather a contact that is near or in proximity thereto. The touch panel 131 capable of floating touch control may be implemented by using a capacitive type, an infrared light sensing type, an ultrasonic wave type, or the like. Alternatively, the touch panel 131 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 180, and receives and executes commands sent from the processor 180. In addition, the touch panel 131 may be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave.
The input unit 130 may include other input devices 132 in addition to the touch panel 131. In particular, other input devices 132 include various peripheral interfaces for providing various interfaces to external input/output devices (e.g., keyboard, mouse, external display, external memory, SIM card, etc.). The peripheral interfaces may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like. For example, a mouse via a usb interface, and a Subscriber Identity Module (SIM) card provided by a telecommunications carrier via metal contacts on a card slot of the SIM card. The peripheral interfaces may be used to couple the aforementioned external input/output peripherals to the processor 180 and the memory 103.
The display unit 140 may be used to display information input by a user or information provided to the user and various menus of the mobile phone. The display unit 140 may include a display panel 141, which may also be referred to as a display or a display screen, and optionally, the display panel 141 may be configured in the form of a Liquid Crystal Display (LCD), an organic light-emitting diode (OLED), or the like. Further, the touch panel 131 can cover the display panel 141, and when the touch panel 131 detects a touch operation on or near the touch panel 131, the touch operation is transmitted to the processor 180 to determine the type of the touch event, and then the processor 180 provides a corresponding visual output on the display panel 141 according to the type of the touch event.
The position of the visual output external display panel 141 that can be recognized by the human eye may be referred to as a "display region" to be described later. Although the touch panel 131 and the display panel 141 are shown as two separate components in fig. 1 to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 131 and the display panel 141 may be integrated to implement the input and output functions of the mobile phone. The touch panel 131 may be overlaid on the display unit 140, and when the touch panel 131 detects a touch event thereon or nearby, the touch event is transmitted to the processor 180 to determine the type of the touch event, and then the processor 180 may provide a corresponding visual output on the display unit 140 according to the type of the touch event. Although in fig. 1 the touch panel 131 and the display unit 140 are implemented as two separate components to implement the input and output functions of the mobile phone 100, in some embodiments, the touch panel 131 and the display unit 140 may be integrated to implement the input and output functions of the mobile phone 100. It is understood that the touch panel 131 is formed by stacking multiple layers of materials, only the touch-sensitive surface (layer) and the display screen (layer) are shown in this embodiment, and the description of the other layers is omitted in this embodiment. In addition, in some other embodiments of the present application, the touch panel 131 may be covered on the display unit 140, and the size of the touch panel 131 is larger than that of the display panel 141, so that the display panel 141 is completely covered under the touch panel 131, or the touch panel 131 may be configured on the front of the mobile phone 100 in a full-panel manner, that is, the touch of the user on the front of the mobile phone 100 can be sensed by the mobile phone, so that the full-touch experience on the front of the mobile phone can be achieved. In other embodiments, the touch panel 131 may be disposed on the front surface of the mobile phone 100 in a full panel manner, and the display panel 141 may be disposed on the front surface of the mobile phone 100 in a full panel manner, so that a bezel-free structure can be implemented on the front surface of the mobile phone. In some other embodiments of the present application, the touch panel 131 may further include a series of pressure sensor arrays, which may enable the cell phone to sense the pressure applied to the touch panel 131 by the touch event.
The handset 100 may also include bluetooth means for enabling data exchange between the handset 100 and other short-range electronic devices, such as cell phones, smart watches, etc. The bluetooth device in the embodiment of the present application may be an integrated circuit or a bluetooth chip.
In addition, the handset 100 may also include at least one sensor 150, such as a fingerprint sensor, motion sensor, light sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display of the touch panel 131 according to the brightness of ambient light, and a proximity sensor that turns off the power of the display when the mobile phone 100 is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the acceleration in each direction (generally three axes), detect the gravity when stationary, and can be used for applications of recognizing the gesture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer gesture calibration), vibration recognition related functions (such as pedometer and tapping), and the like.
In some embodiments of the present application, the sensor 150 may also include a fingerprint sensor. For example, the fingerprint sensor may be disposed on the back side of the cellular phone 100 (e.g., below the rear camera), or the fingerprint sensor may be disposed on the front side of the cellular phone 100 (e.g., below the touch panel 131). In addition, the fingerprint recognition function may be implemented by configuring a fingerprint sensor in the touch panel 131, that is, the fingerprint sensor may be integrated with the touch panel 131 to implement the fingerprint recognition function of the mobile phone 100. In this case, the fingerprint sensor may be disposed in the touch panel 131, may be a part of the touch panel 131, or may be otherwise disposed in the touch panel 131. In addition, the fingerprint sensor may be implemented as a full panel fingerprint sensor, and thus, the touch panel 131 may be regarded as a panel that can perform fingerprint collection at any position. The fingerprint sensor may send the captured fingerprint to the processor 180 for processing (e.g., fingerprint verification, etc.) of the fingerprint by the processor 180. The fingerprint sensor in embodiments of the present application may employ any type of sensing technology including, but not limited to, optical, capacitive, piezoelectric, or ultrasonic sensing technologies, among others.
In the embodiment of the present application, the fingerprint sensor listed above may be used as the element for obtaining fingerprint data, but the present invention is not limited thereto, and other sensors capable of obtaining fingerprint data fall within the scope of the present application.
The light sensor may include an ambient light sensor for adjusting the brightness of the display panel 141 according to the brightness of ambient light, and a proximity sensor for turning off the display panel 141 and/or the backlight when the mobile phone is moved to the ear.
In addition, in the embodiment of the present application, as the sensor 150, other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor may be further configured, which are not described herein again.
Audio circuitry 160, speaker 161, and microphone 162 may provide an audio interface between the user and the handset. The audio circuit 160 may transmit the electrical signal converted from the received audio data to the speaker 161, and convert the electrical signal into a sound signal for output by the speaker 161; on the other hand, the microphone 162 converts the collected sound signal into an electrical signal, which is received by the audio circuit 160 and converted into audio data, which is then processed by the audio data output processor 180 and then transmitted to, for example, another cellular phone via the RF circuit 110, or the audio data is output to the memory 120 for further processing.
The wifi device 170 is used for providing network access for the mobile phone 100 according to wifi related standard protocols, the mobile phone 100 can be accessed to a wifi access point through the wifi device 170, and therefore the mobile phone helps a user to receive and send e-mails, browse webpages, access streaming media and the like, and wireless broadband internet access is provided for the user. In some other embodiments, the wifi device 170 may also be a wifi wireless access point, which may provide wifi network access to other electronic devices.
A positioning device 101 for providing a geographical location for the handset 100.

In some other embodiments, the positioning device 101 may also be a wifi access point based positioning technology. Since each WIFI access point has a globally unique MAC address, the mobile phone 100 can scan and collect broadcast signals of surrounding WIFI access points when the WIFI is turned on, and thus can acquire the MAC address broadcasted by the WIFI access point; the mobile phone 100 sends the data (such as the MAC address) capable of indicating the wifi access point to the location server through the wireless communication network, the location server retrieves the geographic location of each wifi access point, and calculates the geographic location of the mobile phone 100 and sends the geographic location of the mobile phone 100 to the positioning device 101 of the mobile phone 100 according to the strength of the wifi broadcast signal.

Although fig. 1 shows the WiFi module 170, it is understood that it does not belong to the essential constitution of the handset 100, and may be omitted entirely as needed within the scope of not changing the essence of the application.
It is understood that the mobile phone 100 may further include a power system 190 (such as a battery and a power management chip) for supplying power to each component, and the battery may be logically connected to the processor 180 through the power management chip, so as to implement functions of managing charging, discharging, and power consumption through the power system 190.

For ease of understanding, some descriptions of concepts related to the embodiments of the present application are given by way of illustration and reference.
A HALL (HALL) sensor is a device fabricated according to the HALL effect of a semiconductor, which is one of the magnetoelectric effects. The hall effect is essentially the deflection of moving charged particles in a magnetic field by the action of lorentz forces, which for semiconductors results in an accumulation of positive and negative charges in the direction of the vertical current and magnetic field, thus forming an additional lateral electric field.
At present, in the existing flip phone, a hall device is widely used to determine the open or closed state of the phone. The specific working principle is that under the action of a magnetic field, a magnetic field signal is utilized to control a circuit switching device, and the on-off action is directly generated. The Hall sensor is an electronic element, the external form of the Hall sensor is very similar to that of a triode, the Hall sensor specifically comprises a Hall element, an amplifier, a Schmitt circuit and a collector open-circuit output triode, when a magnetic field acts on the Hall element, a tiny Hall voltage is generated, the triode is conducted to output a low level after being amplified by the amplifier and the Schmitt circuit, and when the magnetic field does not act (namely after a flip cover is opened), the triode is cut off and output a high level. When the flip of the mobile phone is opened, no magnetic field force acts, the output of the triode is high level, and when the flip of the mobile phone is closed, the magnetic field force acts to generate tiny voltage and output low level.
In practical applications, whether the hall sensor is turned on or not is completely controlled by a hall high level signal output by a Central Processing Unit (CPU) of the mobile phone, and a power supply is from a battery. When the flip cover is closed, under the action of a magnetic field, hall voltage is generated, and after the Hall voltage is conducted through the triode, a low level is output from a pin of the Hall sensor. If the call is after the call, the call is taken as an on-hook signal to be sent to the CPU to be on-hook.
The terminal judges the opening or closing state of the folding mobile phone by using the Hall device, but the Hall device occupies a larger space and has higher cost, so that the space optimization and the cost optimization of the terminal are not facilitated; moreover, the hall device needs a magnet mounted on the flip to generate a magnetic field, which may cause interference problems to the radio frequency of the antenna. This application provides a new detection scheme to future collapsible screen terminal equipment, replaces hall device to realize carrying out space optimization, improvement user experience to terminal equipment opening or closed state's detection, when reduce cost.
It should be understood that the detection method provided by the present application is applied to a folding screen terminal device configured with a capacitive screen, and the present application will be described in detail by taking a mobile phone as an example.
First, a brief description will be given of the capacitive screen. The capacitive screen is a composite glass screen (plastic screen) which works by means of current induction, the induction layer of the touch screen is made of transparent conductive materials to realize mutual induction capacitance or ground induction capacitance, and the touch position and the touch mode are judged according to the capacitance variation when a finger touches the touch screen. The conductive material is usually Indium Tin Oxide (ITO) or nano silver, and is attached to a substrate (glass, PET, PI, or the like). The capacitive screen can increase the number of electrodes of the capacitor to realize multi-point touch.
Specifically, the screen of the terminal is partitioned, interactive capacitor modules are arranged in each partitioned area, and each group of capacitor modules work independently or work in combination with surrounding capacitor modules, so that the capacitive screen can independently detect the touch condition of each area, and after processing, multi-point touch is simply realized. When a user touches the capacitive screen, a coupling capacitor is formed between the finger of the user and the working surface of the capacitive screen due to a human body electric field, and when the finger clicks the capacitive screen, the finger can absorb a small amount of current (for example, a few microamperes) from a contact of the capacitive screen, so that the voltage drop of electrodes arranged at four corners of the capacitive screen is caused, and the position coordinate of a touch point is analyzed. Fig. 2 is a schematic diagram of a touch-sensitive area of an exemplary mobile phone configuration provided in the present application, such as the mobile phone 201 shown in fig. 2, in which a foldable terminal is divided into two folding areas along a folding axis 203, an upper half 202 of the foldable mobile phone is referred to as a "first area", and a lower half 204 of the foldable mobile phone is referred to as a "second area". In addition, a plurality of touch sensing points 205 may be configured for the terminal, and an area where the touch sensing points are located is referred to as a "touch sensing area", "touch area", or "sensing area" in this application, for example, a first touch sensing area and a second touch sensing area. In the description of the embodiments of the present application, the potential difference between corresponding touch sensing areas of the capacitive screen will be described by taking the potential difference between a set of corresponding touch sensing points as an example. It should be understood that one touch sensing area may also include a plurality of touch sensing points, which is not limited in this application.
It should be understood that only two pairs of touch sensing points are shown in fig. 2, touch sensing point 1 and touch sensing point 3 being sensing areas disposed on the first area 202, and touch sensing point 2 and touch sensing point 4 being sensing areas disposed on the second area 204. The touch sensing point 1 and the touch sensing point 2 are a pair of touch sensing areas of the mobile phone 201 corresponding to each other, and when the mobile phone 201 is folded, that is, the projection of the touch sensing point 1 on the second area 204 overlaps with the touch sensing point 2, in other words, when the screen is folded and closed, the touch sensing point 1 and the touch sensing point 2 are overlapped. Similarly, the touch sensing point 3 and the touch sensing point 4 are also a pair of mutually sensing touch sensing areas. In addition, the touch sensing points 205 can be understood as a conductor, similar to the ITO described above, capable of receiving charging and discharging of the mobile phone, and the capacitance value between each pair of touch sensing points can change with the charging and discharging of the mobile phone or the change of the distance.
It should also be understood that a capacitance value between touch-sensitive points can be understood as a potential difference between two touch-sensitive points. In particular, in circuitries, at a certain potential difference (1U), the capacity of a capacitor to store charge, called capacitance, is marked C. Adopting an international unit system, wherein the unit of the capacitor is Farad (farad), and is called the method for short; labeled as F. The symbol of the capacitor is C, and the capacitor C can be obtained according to the following formula (1) under vacuum conditions.
C＝εS/d＝εS/4πkd＝Q/U (1)
Where ε is an electrical constant, S is the area of one face of the capacitor plate, d is the distance between the electrodes, and k is the constant of the electrostatic force. As can be seen from the above equation (1), the capacitance and the distance d between the electrodes are inversely proportional, increasing with the distance between the electrodes. It should be understood that, in the embodiment of the present application, as the distance between the touch sensing points changes, the mobile phone may determine whether to turn on or turn off the screen by detecting a change in capacitance values between the touch sensing points; in other words, the mobile phone can determine whether to light or extinguish the screen by detecting the change in the potential difference between the touch-sensitive points.
It should be understood that the light-up screen or the light-off screen may include a plurality of possible application scenarios, and fig. 3 is a schematic diagram of several possible light-up screens provided by the embodiments of the present application. For example, in the schematic diagram shown in FIG. 3-a, the lighted-up screen may be from a locked state where the screen is extinguished to an unlocked page; or the schematic diagram shown in fig. 3-b, the lighted-up screen may be from a lock screen state of the extinguished screen to a lock screen state of the lighted-up screen; or, if the mobile phone is in the unlocked state, the lighting screen can be directly switched from the off screen locking state to the home page state of the mobile phone. The screen can be extinguished according to different scenes, for example, in the process of opening the mobile phone to closing the mobile phone, the mobile phone can be extinguished and locked, or only extinguished and unlocked, and the user can wake up the screen through touch and other operations without speaking to unlock the mobile phone until the mobile phone is completely folded and closed and then enters the locked state. This is not a limitation of the present application.
In addition, it should be understood that, in the present application, the distribution of the touch sensing points is correspondingly arranged in the first area 202 and the second area 204, but specifically in each area, the distribution of the touch sensing points is not limited to the point-like distribution, the strip-like distribution or the distribution in other shapes.
In a specific implementation process, the terminal may determine a current open/close state of the terminal, for example, a folding or closing process, by testing a change in capacitance values between the multiple groups of touch sensing points. Or, the terminal may determine the current on-off state of the terminal according to the change rule of the common capacitance values among the multiple groups of touch sensing points, for example, by setting three groups of touch sensing points, where a capacitance value between the touch sensing point 1 and the touch sensing point 2 is 0.8V, a capacitance value between the touch sensing point 3 and the touch sensing point 4 is 0.9V, and a capacitance value between the touch sensing point 5 and the touch sensing point 6 is 1.0V; in the state 2, the capacitance between the touch sensing point 1 and the touch sensing point 2 is 0.4V, the capacitance between the touch sensing point 3 and the touch sensing point 4 is 0.45V, and the capacitance between the touch sensing point 5 and the touch sensing point 6 is 0.5V. In the process that the terminal judges that the state is from the state 1 to the state 2, the change rule of the three continuous groups of touch induction points is consistent with the preset rule, and the state of the terminal can also be judged. It should be understood that the present application is not limited to the arrangement rule of the above-listed sets of touch sensing points, and for example, the touch sensing points may be in a dot shape, a stripe shape, or a bar shape, and the number of the sets of touch sensing points is also not limited. In a possible implementation manner, a distance between the first touch sensing area and the first axis is greater than or equal to a third threshold, and a distance between the second touch sensing area and the first axis is greater than or equal to the third threshold. The third threshold value is set here, and the sensitivity of the change in the potential difference between a group of touch-sensitive points can be ensured. The touch sensing points can be configured to be farther from the folding axis, because as the folding angle decreases, if the touch sensing points are closer to the folding axis, two touch sensing points will be in an infinite proximity state, which is not favorable for measuring the potential difference.
For example, in configuring a plurality of sets of touch sensing points, it is preferable to configure the touch sensing points at upper and lower edge positions of the capacitive screen, such as touch sensing points 1, 2, 3, and 4 shown in fig. 2-a. Under the condition, the distance between the touch sensing point and the folding shaft is larger, so that the sensitivity of potential difference change is facilitated, and the detection of the potential difference by the mobile phone is facilitated.
Fig. 4 is a schematic flowchart of a method for controlling opening and closing of a screen according to an embodiment of the present application. It will be appreciated that the method may be applied to an electronic device having a foldable capacitive screen that is foldable about a first axis, the foldable capacitive screen comprising a first portion in which a first touch sensitive area is provided and a second portion in which a second touch sensitive area is provided on either side of the first axis, the electronic device being capable of applying a first electrical potential to the first touch sensitive area and a second electrical potential to the second touch sensitive area. The method includes steps S401-S406, each of which is described in detail below.
S401, start. The mobile phone is in an operating state, and can be charged and discharged regularly, for example.
S402, the control unit of the mobile phone controls the power supply module to apply a first electric potential to the first touch sensing area, and can apply a second electric potential to the second touch sensing area. Namely, charging and discharging are carried out on touch sensing points arranged in the mobile phone capacitive screen, and electric potential is applied to a corresponding pair of touch sensing points.
S403, detecting the potential difference between the first touch sensing area and the second touch sensing area by a detection device.
S404, the control device judges the range of the potential difference between the first touch sensing area and the second touch sensing area, and lights or lights out the foldable capacitive screen according to the range of the potential difference between the first touch sensing area and the second touch sensing area.
S405, when the foldable capacitive screen is in an off state and the potential difference is smaller than or equal to a preset first threshold value, the control device lights the foldable capacitive screen.
S406, when the foldable capacitive screen is in a lighting state and the potential difference is larger than or equal to a preset second threshold value, the control device extinguishes the foldable capacitive screen.
It should be understood that the potential difference between the first touch-sensitive area and the second touch-sensitive area varies in different states of the mobile phone, and the following detailed description will be made with specific reference to the process of the mobile phone from being folded closed to being opened, and from being opened to being folded closed.

As shown in fig. 5, the process of gradually opening the mobile phone from the folded state may include three cases, that is, the angle between the first region 202 and the second region 204 shown in fig. 5 (a) is less than 90 °, the angle between the first region 202 and the second region 204 shown in fig. 5 (b) is 90 °, and the angle between the first region 202 and the second region 204 shown in fig. 5 (c) is greater than 90 °. In addition, the black solid points in fig. 5 indicate the touch sensing points of the present application, and the distance between a pair of touch sensing points is d, it should be understood that d may be the distance of a straight line between the geometric centers of two touch sensing points.
Optionally, the mobile phone performs regular charging and discharging on the capacitive screen through chip control. Optionally, the mobile phone charges and discharges the capacitive screen regularly according to a sine wave curve, for example, the frequency f =90KHz. This is not a limitation of the present application.
For regular charging and discharging controlled by a mobile phone chip, charges can be respectively accumulated in the areas of the two touch induction points, for example, after the first area 202 is charged by the mobile phone, a large amount of positive charges are accumulated, and after the second area 204 is charged by the mobile phone, a large amount of negative charges are accumulated, so that a potential difference is formed between the positive charges and the negative charges, that is, an induction electric field is formed between the areas where the two touch induction points are located, which is similar to an electric field between parallel plates. Fig. 6 is a schematic diagram of an electric field between touch sensing points according to an embodiment of the present disclosure. As shown in fig. 6, when the mobile phone is opened from the folded state to an angle α (α <90 °), a corresponding distance between the two touch sensitive areas is d, a potential difference between the two touch sensitive areas is U, and an electric field strength is E, the following formula (2) is satisfied between d, U, and E:
