Description

Method and device for correcting approaching state, mobile terminal and storage medium

Technical Field

The present application relates to the field of mobile terminal technologies, and in particular, to a method and an apparatus for correcting a proximity state, a mobile terminal, and a storage medium.

Background

Mobile terminals, such as mobile phones, have become one of the most common consumer electronics products in people's daily life. With the development of science and technology, a full screen is gradually popularized, and the front face of the mobile terminal has almost no space for arranging a near infrared Sensor, so that an electromagnetic wave Absorption Ratio (SAR Specific, Absorption Ratio Sensor) Sensor is adopted to replace the near infrared Sensor. The SAR sensor is placed near an antenna area of the mobile phone, and changes of peripheral capacitance are sensed through the antenna, so that whether a human body approaches the mobile terminal or not is determined. However, when the mobile terminal is placed on a desktop or on the legs of a person, the SAR sensor may detect the capacitance change, which may cause a misjudgment that a human body is close to the mobile terminal, and may cause inconvenience to the user in using the mobile terminal.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The display screen generally plays a role in a mobile terminal such as a mobile phone or a tablet computer to display contents such as text, pictures, icons or videos. With the development of touch technologies, more and more display screens arranged on mobile terminals are touch display screens, and when a user is detected to perform touch operations such as dragging, clicking, double clicking, sliding and the like on the touch display screen under the condition of arranging the touch display screens, the touch operation of the user can be responded.

With the increasing requirements of users on the definition and the fineness of displayed contents, more mobile terminals adopt touch display screens with larger sizes to achieve the display effect of a full screen. However, in the process of setting a touch display screen with a large size, it is found that there is no space for setting the near infrared sensor on the front surface of the mobile terminal.

Therefore, an electromagnetic wave absorption ratio (SAR) sensor may be used instead of the near infrared sensor, and disposed near an antenna region inside the mobile terminal. The SAR sensor can sense whether the peripheral capacitance changes through the antenna, and further determine whether a human body approaches the mobile terminal, so that the function of the near-infrared sensor in the mobile terminal can be realized.

However, the inventor finds that after the SAR sensor is used to replace the near infrared sensor, when the mobile terminal is placed on a desktop, or the mobile terminal is placed on a leg of a person, or the surface of the mobile terminal is stained with liquid, etc., the SAR sensor may also detect the capacitance change, which may cause misjudgment that a human body is close to the mobile terminal under these conditions, thereby causing inconvenience to the user using the mobile terminal.

In view of the above problems, the inventors have studied for a long time and proposed a method and an apparatus for correcting an approaching state, a mobile terminal, and a storage medium according to embodiments of the present application, in which when a capacitance change value detected by an SAR sensor is greater than a preset change value in a preset posture of the mobile terminal, the approaching state of the mobile terminal is corrected from a first state to a second state, so that it is not determined that the approaching state of the mobile terminal is the first state in which a human body approaches. Embodiments in the present application will be described in detail below with reference to the accompanying drawings.

In an embodiment, please refer to fig. 1, and fig. 1 is a schematic flowchart illustrating a method for correcting a proximity state according to an embodiment of the present disclosure. According to the method for correcting the approaching state, when the mobile terminal is in the preset posture and the capacitance change value detected by the SAR sensor is larger than the preset change value, the approaching state of the mobile terminal is corrected from the first state to the second state, so that the approaching state of the mobile terminal is not judged to be the first state in which a human body approaches by mistake. In a specific embodiment, the correction method of the proximity state is applied to the correction apparatus 200 of the proximity state as shown in fig. 4 and a mobile terminal configured with the correction 200 of the proximity state. The following will describe a specific process of this embodiment by taking a mobile terminal as an example, and it is understood that the mobile terminal applied in this embodiment may be a smart phone, a tablet computer, a wearable electronic device, and the like, which is not limited specifically herein. As will be explained in detail with respect to the flow shown in fig. 1, the above-mentioned approach state correction method may specifically include the steps of:

step S110: and monitoring the posture of the mobile terminal.

In the using process of the mobile terminal, the probability that the SAR sensor is interfered is high, for example, the SAR sensor is influenced by sweat, for example, the mobile terminal is placed on a leg, for example, the mobile terminal is placed on a table top made of metal materials, and due to capacitance interference, the SAR sensor can detect the change of capacitance, and the SAR sensor can be judged to be a human body approaching the mobile terminal by mistake. However, if the current posture of the mobile terminal is in some special postures, the user is substantially impossible to approach the mobile terminal, and thus the approach state misjudged by the mobile terminal can be corrected by while in these special states.

In the embodiment of the application, the gesture of the mobile terminal can be monitored to obtain the gesture of the mobile terminal in real time, and whether the gesture of the mobile terminal is a preset gesture is judged, so that whether the approaching state of the mobile terminal needs to be corrected or not is determined in the following.

Furthermore, the gesture of the mobile terminal can be acquired in real time through an acceleration sensor of the mobile terminal. The acceleration sensor detects the X, Y, Z axis acceleration of the acceleration sensor of the mobile terminal, so that the attitude of the mobile terminal can be obtained, that is, the included angle between the X, Y, Z axis of the acceleration sensor (corresponding to the mobile terminal) and each plane in space is obtained.

Of course, the specific manner of monitoring the gesture of the mobile terminal is not limited in the embodiment of the present application, and other manners may also be used, for example, by providing a gesture sensor to the mobile terminal, the gesture of the mobile terminal is detected.

Step S120: when the gesture of the mobile terminal is a preset gesture, whether a capacitance change value detected by an electromagnetic wave absorption ratio (SAR) sensor of the mobile terminal is larger than a preset change value or not is judged, and the preset change value is used for judging that the approaching state of the mobile terminal is a first state when the capacitance change value detected by the SAR sensor is larger than the preset change value.

In the embodiment of the application, when the gesture of the mobile terminal is monitored to be the preset gesture that a human body cannot approach the mobile terminal, the approaching state of the mobile terminal, which is judged when the capacitance change value detected by the SAR sensor is larger than the preset change value, can be corrected.

As an embodiment, the preset posture may be a horizontal posture. It can be understood that, when the mobile terminal is in the horizontal posture, for example, the mobile terminal is placed on a table top made of a metal material, or is prevented from being placed on a thigh of a human body, and both the mobile terminal and the mobile terminal are in the horizontal posture, at this time, interference is caused to the capacitance detected by the SAR sensor, so that the SAR sensor detects the capacitance change, and it is determined that a human body is close to the mobile terminal. At this time, the user is not really close to the mobile terminal, and therefore, the proximity state of the mobile terminal needs to be corrected.

Furthermore, when the gesture of the mobile terminal is detected to be the preset gesture, the capacitance change value detected by the SAR sensor needs to be judged, and only when the capacitance change value detected by the SAR sensor is larger than the preset change value, the approaching state of the mobile terminal needs to be corrected.

It can be understood that, when the gesture of the mobile terminal is the preset gesture, the capacitance change value detected by the SAR sensor is not greater than the preset change value, and it is not determined that a human body approaches the mobile terminal at this time, that is, the determined approach state of the mobile terminal is the correct approach gesture, and the approach state does not need to be corrected. And when the gesture of the mobile terminal is the preset gesture and the capacitance change value detected by the SAR sensor is larger than the preset change value, the judged approach state is the misjudged approach state, and the approach state needs to be corrected.

The preset change value is used as a condition for judging the approaching state of the mobile terminal, and when the capacitance change value detected by the SAR sensor is larger than the preset change value, the approaching state of the mobile terminal is judged to be a first state, and the first state indicates that a human body approaches the mobile terminal. And when the capacitance change value detected by the SAR sensor is not greater than the preset change value, judging that the approaching state of the mobile terminal is a second state, wherein the second state represents that no human body approaches the mobile terminal.

For example, when the capacitance change value detected by the SAR sensor is greater than 50pf, it is considered that a human body approaches the mobile terminal, and relevant processing, such as screen-off and other processing, is performed on a first state in which the human body approaches the mobile terminal; when the capacitance change value detected by the SAR sensor is not more than 50pf, it is considered that no human body approaches the mobile terminal, and the current state of the mobile terminal is maintained. Of course, the above numerical values of the preset variation values are only examples, and do not limit the preset variation values in the embodiments of the present application.

Step S130: and if the value is larger than the preset change value, correcting the approaching state of the mobile terminal from the first state to a second state.

In the embodiment of the application, when the capacitance change value detected by the SAR sensor is judged to be greater than the preset change value, the approaching state of the mobile terminal is judged to be the first state, that is, the state that a human body approaches the mobile terminal is judged. The current gesture of the mobile terminal is a preset gesture, that is, a human body does not really approach the mobile terminal, so that the currently determined approaching state of the mobile terminal is wrong. Therefore, it is necessary to correct the proximity state of the mobile terminal, specifically, correct the proximity state of the mobile terminal from the first state to the second state, that is, correct the proximity state of the mobile terminal from a state in which a human body approaches the mobile terminal to a state in which an unmanned body approaches the mobile terminal, so that the screen state of the mobile terminal, etc., is a state when the unmanned body approaches the mobile terminal, thereby ensuring normal use of the mobile terminal by the user.

In the embodiment of the application, when the capacitance change value detected by the SAR sensor is judged to be not greater than the preset change value, the approaching state of the mobile terminal is judged to be the second state, namely the state that no human body approaches the mobile terminal, and the judged approaching state of the mobile terminal is accurate, so that the approaching state of the mobile terminal does not need to be corrected.

According to the correction method of the approaching state, by monitoring the gesture of the mobile terminal, when the gesture of the mobile terminal is the preset gesture, whether the capacitance change value detected by the SAR sensor is larger than the preset change value or not is judged, and if the capacitance change value is larger than the preset change value, the first state that a human body approaches the mobile terminal is judged to be wrong, so that the approaching state of the mobile terminal is corrected from the first state to the second state that the human body approaches the mobile terminal. Therefore, when the capacitance change value detected by the SAR sensor is larger than the preset change value under the condition that the mobile terminal is in the preset posture, the approach state of the mobile terminal cannot be judged to be the first state that a human body approaches, and the normal use of the mobile terminal by a user can be ensured.

In an embodiment, please refer to fig. 2, and fig. 2 is a schematic flowchart illustrating a method for correcting a proximity state according to an embodiment of the present disclosure. As will be described in detail with respect to the flow shown in fig. 2, the method for correcting the approaching state may specifically include the following steps:

step S210: and monitoring the posture of the mobile terminal.

Step S220: and judging whether the included angle between the mobile terminal and the horizontal plane is smaller than a preset angle or not based on the posture of the mobile terminal.

In the embodiment of the application, whether an included angle between the mobile terminal and a horizontal plane is smaller than a preset angle or not can be judged according to the monitored posture of the mobile terminal, so that whether the mobile terminal is in a state that a user is unlikely to approach the mobile terminal or not is judged.

It will be appreciated that the user is less likely to approach the mobile terminal when the mobile terminal is in a horizontal position or when the mobile terminal is at a small angle to the horizontal. Therefore, whether the included angles between the X axis and the horizontal plane of the mobile terminal and the included angles between the Y axis of the mobile terminal and the horizontal plane are smaller than the preset angle or not is judged, and when the included angles between the mobile terminal and the horizontal plane are smaller than the preset angle or not, whether the mobile terminal is in a state that a user is unlikely to approach the mobile terminal or not is indicated, so that the approach state of the mobile terminal, which is judged when the capacitance change value detected by the SAR sensor is larger than the preset change value, can be corrected to be the first state.

In the embodiment of the present application, the preset angle may be 20 ° to 40 °. As an optional implementation manner, the preset angle may be 30 °, that is, when the included angle between the mobile terminal and the horizontal plane is less than 30 °, it is required to correct that the determined approach state of the mobile terminal is the first state when the capacitance change value detected by the SAR sensor is greater than the preset change value. Of course, the above preset angle is only an example, and does not constitute a limitation on the preset angle in the embodiment of the present application.

Step S230: and if the capacitance change value is smaller than the preset angle, judging whether the capacitance change value detected by the SAR sensor of the mobile terminal is larger than a preset change value.

And when the included angle between the mobile terminal and the horizontal plane is judged to be smaller than the preset angle, judging whether the capacitance change value detected by the SAR sensor of the mobile terminal is larger than the preset change value or not so as to determine whether the approaching state of the mobile terminal needs to be corrected or not.

When the included angle between the mobile terminal and the horizontal plane is judged to be not smaller than the preset angle, the judged approach state of the mobile terminal is the first state without correcting the capacitance change value detected by the SAR sensor to be larger than the preset change value, and the approach state judged by the mobile terminal according to the capacitance change value detected by the SAR sensor can be used as the real approach state.

Step S240: and if the capacitance change value is larger than the preset change value, adjusting the capacitance change value detected by the SAR sensor to a target value, wherein the target value is smaller than the preset change value.

In the embodiment of the application, when it is determined that the capacitance change value detected by the SAR sensor is greater than the preset change value, the currently determined proximity state of the mobile terminal is a first state in which a human body approaches the mobile terminal, the proximity state of the mobile terminal needs to be corrected, and the proximity state of the mobile terminal is corrected from the first state to a second state in which no human body approaches the mobile terminal.

As in the previous embodiment, when it is determined that the capacitance variation value detected by the SAR sensor is not greater than the preset variation value, it is determined that the proximity state of the mobile terminal is the second state, that is, the state in which no human body is in proximity to the mobile terminal, and if it is determined that the proximity state of the mobile terminal is accurate, the proximity state of the mobile terminal does not need to be corrected.

Furthermore, the approaching state of the mobile terminal is corrected from the first state to a second state in which no human body approaches the mobile terminal, and the approaching state of the mobile terminal can be judged to be the second state in which no human body approaches by adjusting the capacitance change value detected by the SAR sensor to a target value smaller than a preset change value.

The capacitance change value detected by the SAR sensor is adjusted to a target value smaller than a preset change value, and the capacitance change value buffered in the memory is adjusted to the target value smaller than the preset change value after the capacitance change value detected by the SAR sensor is output to the processor, so that when the processor judges whether the capacitance change value detected by the SAR sensor is smaller than the preset change value, the target value and the preset change value are compared to compare the target value smaller than the preset change value, and the approach state of the mobile terminal is judged to be a second state without human body approach. Of course, the capacitance change value detected by the SAR sensor may be adjusted to a target value smaller than the preset change value, or the capacitance change value detected by the SAR sensor may be cleared, so that the capacitance change value output by the SAR sensor to the processor is 0, and the above purpose of determining that the approaching state of the mobile terminal is the second state in which no human body approaches may also be achieved.

Step S250: and adjusting the approaching state of the mobile terminal from the first state to a second state according to the target value.

It can be understood that when the capacitance change value detected by the SAR sensor is greater than a preset change value, it is determined that the proximity state of the mobile terminal is the first state; and when the capacitance change value detected by the SAR sensor is not greater than the preset change value, judging that the approaching state of the mobile terminal is a second state. After the capacitance change value detected by the SAR sensor is adjusted to be a target value smaller than the preset change value, the approach state of the mobile terminal can be automatically judged to be the second state according to the fact that the capacitance change value detected by the SAR sensor is the target, and therefore the approach state of the mobile terminal can be adjusted to be the second state from the previous first state, the screen state of the mobile terminal is enabled to be the state when no human body approaches the mobile terminal, and the normal use of the mobile terminal by a user is guaranteed.

Step S260: and when the gesture of the mobile terminal is a preset gesture, if the SAR sensor detects that the capacitance change value is larger than the preset change value again, the approaching state of the mobile terminal is adjusted from the second state to the first state.

In the embodiment of the present application, a situation that the user really approaches the mobile terminal when the posture of the mobile terminal is still the preset posture after the approach state of the mobile terminal is corrected from the first state to the second state under the preset posture is also considered.

For example, in the case where the mobile terminal is placed on a table top or a thigh made of metal. The capacitance change value detected by the SAR sensor is larger than a preset change value, after the judged approaching state is adjusted from the first state to the second state, the user may be under the condition that the mobile terminal is still placed on a desktop or a thigh made of a metal material, the face is close to the mobile terminal, and the like, the SAR sensor can detect a new capacitance change value larger than the preset change value again and output the new capacitance change value to the processor, and at the moment, the processor can judge that the approaching state of the mobile terminal is the first state according to the condition that the current capacitance change value is larger than the preset change value, so that the approaching state of the mobile terminal is adjusted from the second state that no human body approaches the mobile terminal to the first state that a human body approaches the mobile terminal, and the user can use the mobile terminal under the condition that the user approaches the mobile terminal.

According to the correction method for the approaching state, the included angle between the mobile terminal and the horizontal plane is smaller than the preset included angle, and when the capacitance change value detected by the SAR sensor is larger than the preset change value, the approaching state of the mobile terminal is corrected from the first state to the second state, so that the situation that the capacitance change value detected by the SAR sensor is larger than the preset change value under the condition that the mobile terminal is in the preset posture is achieved, the approaching state of the mobile terminal cannot be judged to be the first state that a human body approaches by mistake, and normal use of the mobile terminal by a user can be guaranteed. In addition, when the gesture of the subsequent mobile terminal is still the preset gesture and the user approaches the mobile terminal, the approach state is adjusted to be the first state, so that the user can use the mobile terminal conveniently under the condition of approaching the mobile terminal.

In an embodiment, please refer to fig. 3, and fig. 3 is a flowchart illustrating a method for correcting a proximity state according to an embodiment of the present disclosure. As will be described in detail with respect to the flow shown in fig. 3, the method for correcting the approaching state may specifically include the following steps:

step S310: and monitoring the posture of the mobile terminal.

Step S320: when the gesture of the mobile terminal is a preset gesture, whether a capacitance change value detected by an electromagnetic wave absorption ratio (SAR) sensor of the mobile terminal is larger than a preset change value or not is judged, and the preset change value is used for judging that the approaching state of the mobile terminal is a first state when the capacitance change value detected by the SAR sensor is larger than the preset change value.

Step S330: if the value is larger than the preset change value, the SAR sensor is turned off or the data detected by the SAR sensor is not responded, so that the approaching state of the mobile terminal is corrected from the first state to the second state.

Further, the approach state of the mobile terminal is corrected from the first state to a second state in which no human body approaches the mobile terminal, and the approach state of the mobile terminal can be adjusted to the second state in which no human body approaches by turning off the SAR sensor or not responding to the data detected by the SAR sensor.

It can be understood that, when the SAR sensor is turned off or no response is made to the data detected by the SAR sensor, the processor does not determine that the proximity state of the mobile terminal is the first state in which a human body is approaching according to the capacitance change value detected by the SAR sensor and larger than the preset change value, that is, the proximity state of the mobile terminal is the second state in which no human body is approaching at present, so that the screen state and the like of the mobile terminal are the states when no human body is approaching the mobile terminal, thereby ensuring the normal use of the mobile terminal by the user.

In this embodiment of the application, if the SAR sensor is turned off in the above method, after step S330, the method for correcting the proximity state may further include: and when the gesture of the mobile terminal is other gestures except the preset gesture, starting the SAR sensor. It can be understood that, for normal determination of the subsequent approach state, the SAR sensor may be turned back on when the gesture of the mobile terminal is another gesture in which the user may approach the mobile terminal, so as to ensure normal determination of the first state in which the human body approaches.

The method for correcting the approaching state comprises the steps of monitoring the posture of the mobile terminal, judging whether a capacitance change value detected by the SAR sensor is larger than a preset change value or not when the posture of the mobile terminal is the preset posture, and if the capacitance change value is larger than the preset change value, closing the SAR sensor or not responding data detected by the SAR sensor, so that the approaching state of the current mobile terminal is a second state that an unmanned body approaches the mobile terminal.

In one embodiment, referring to fig. 4, fig. 4 is a block diagram of a correction apparatus 400 for a proximity status according to an embodiment of the present disclosure. As will be explained below with respect to the block diagram shown in fig. 4, the approaching state correction apparatus 400 includes: an attitude monitoring module 410, a capacitance determination module 420, and a state correction module 430. The gesture monitoring module 410 is configured to monitor a gesture of the mobile terminal; the capacitance determining module 420 is configured to determine whether a capacitance change value detected by an SAR sensor of the mobile terminal is greater than a preset change value when the gesture of the mobile terminal is a preset gesture, where the preset change value is used to determine that the approaching state of the mobile terminal is a first state when the capacitance change value detected by the SAR sensor is greater than the preset change value; the state correcting module 430 is configured to correct the proximity state of the mobile terminal from the first state to a second state if the proximity state is greater than the preset variation value.

In this embodiment, the preset gesture may be a horizontal gesture.

In this embodiment, the capacitance determining module 420 may be specifically configured to: judging whether an included angle between the mobile terminal and a horizontal plane is smaller than a preset angle or not based on the posture of the mobile terminal; and if the capacitance change value is smaller than the preset angle, judging whether the capacitance change value detected by the SAR sensor of the mobile terminal is larger than a preset change value.

In the embodiment of the present application, please refer to fig. 5, the state correction module 430 may include a variation value adjustment unit 431 and a state adjustment unit 432. The change value adjusting unit 431 is configured to adjust the capacitance change value detected by the SAR sensor to a target value if the capacitance change value is greater than the preset change value, where the target value is smaller than the preset change value; the state adjusting unit 432 is configured to adjust the proximity state of the mobile terminal from the first state to a second state according to the target value.

In this embodiment of the present application, the state correction module 430 may be specifically configured to: if the capacitance value is larger than the preset capacitance value, the SAR sensor is turned off or the data detected by the SAR sensor is not responded, so that the approaching state of the mobile terminal is corrected from the first state to the second state.

Further, the approaching state correction apparatus 400 may further include an opening control module. The starting control module is used for starting the SAR sensor when the gesture of the mobile terminal is other gestures except the preset gesture.

In the embodiment of the present application, the approaching state correction apparatus 400 may further include a state adjustment module. The state adjusting module is used for adjusting the approaching state of the mobile terminal from the second state to the first state when the attitude of the mobile terminal is a preset attitude and if the SAR sensor detects that the capacitance change value is larger than the preset change value again.

In an embodiment, referring to fig. 6, based on the above method and apparatus for calibrating a proximity state, the present application further provides a mobile terminal 100 capable of performing the method for calibrating a proximity state. The mobile terminal 100 includes one or more processors 102 (only one shown), memory 104, and a SAR sensor coupled to each other. The number of the SAR sensors can be set according to needs. The memory 104 stores a program corresponding to the method for correcting the proximity state provided in the above embodiment, and the processor 102 may execute the program stored in the memory 104.

To sum up, compared with the prior art, the method and the device for correcting the approaching state, the mobile terminal and the storage medium provided by the application judge whether a capacitance change value detected by an electromagnetic wave absorption ratio (SAR) sensor of the mobile terminal is greater than a preset change value or not by monitoring the posture of the mobile terminal when the posture of the mobile terminal is the preset posture, wherein the preset change value is used for judging that the approaching state of the mobile terminal is a first state when the capacitance change value detected by the SAR sensor is greater than the preset change value, and finally, if the capacitance change value is greater than the preset change value, the approaching state of the mobile terminal is corrected from the first state to a second state. Therefore, when the capacitance change value detected by the SAR sensor is larger than the preset change value under a certain posture of the mobile terminal, the approach state of the mobile terminal cannot be judged to be the first state that a human body approaches.

It should be noted that, in the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.

The mobile terminal 100 includes one or more (only one shown) processors 102, memory 104, wireless module 106, audio circuitry 110, sensors 114, input module 118, and power module 132. It will be understood by those of ordinary skill in the art that the present application is not limited to the structure of the mobile terminal 100. For example, the mobile terminal 100 may also include more or fewer components than shown, or have a different configuration than shown.

Those skilled in the art will appreciate that all other components are peripheral devices with respect to the processor 102, and the processor 102 is coupled to the peripheral devices through a plurality of peripheral interfaces 124. The peripheral interface 124 may be implemented based on the following criteria: universal Asynchronous Receiver/Transmitter (UART), General Purpose Input/Output (GPIO), Serial Peripheral Interface (SPI), and Inter-Integrated Circuit (I2C), but the present invention is not limited to these standards. In some examples, the peripheral interface 124 may comprise only a bus; in other examples, the peripheral interface 124 may also include other elements, such as one or more controllers, for example, a display controller for interfacing with the display panel 111 or a memory controller for interfacing with a memory. These controllers may also be separate from the peripheral interface 124 and integrated within the processor 102 or a corresponding peripheral.

The memory 104 may be used to store software programs and modules, and the processor 102 executes various functional applications and data processing by executing the software programs and modules stored in the memory 104. The memory 104 may include high speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid state memory. In some examples, the memory 104 may further include memory remotely located from the processor 102, which may be connected to the mobile terminal 100 or the first screen 130 over a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The wireless module 106 is configured to receive and transmit electromagnetic waves, and achieve interconversion between the electromagnetic waves and electrical signals, so as to communicate with a communication network or other devices. The wireless module 106 may include various existing circuit elements for performing these functions, such as an antenna, a radio frequency transceiver, a digital signal processor, an encryption/decryption chip, a Subscriber Identity Module (SIM) card, memory, and so forth. The wireless module 106 may communicate with various networks, such as the internet, an intranet, a wireless network, or with other devices via a wireless network. The wireless network may comprise a cellular telephone network, a wireless local area network, or a metropolitan area network. The Wireless network may use various Communication standards, protocols, and technologies, including, but not limited to, Global System for Mobile Communication (GSM), Enhanced Mobile Communication (Enhanced Data GSM Environment, EDGE), wideband Code division multiple Access (W-CDMA), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Wireless Fidelity (WiFi) (e.g., Institute of Electrical and Electronics Engineers (IEEE) standard IEEE 802.10A, IEEE802.11 b, IEEE802.1 g, and/or IEEE802.11 n), Voice over internet protocol (VoIP), world wide mail Access (Microwave for Wireless Communication), Wi-11 Wireless Access (wimax), and any other suitable protocol for instant messaging, and may even include those protocols that have not yet been developed.

The camera 121 is used to capture images and pass them to the process 102 for processing. The camera 121 is driven by a motor (not shown in the figure) to extend or retract to be hidden in the terminal body. The motor executes an action of driving the camera 121 to extend or retract in response to a control instruction sent by the processor.

The audio circuit 110, the speaker 101, the sound jack 103, and the microphone 105 collectively provide an audio interface between a user and the mobile terminal 100 or the first screen 130. Specifically, the audio circuit 110 receives sound data from the processor 102, converts the sound data into an electrical signal, and transmits the electrical signal to the speaker 101. The speaker 101 converts an electric signal into a sound wave audible to the human ear. The audio circuitry 110 also receives electrical signals from the microphone 105, converts the electrical signals to sound data, and transmits the sound data to the processor 102 for further processing. Audio data may be retrieved from the memory 104 or through the wireless module 106. In addition, audio data may also be stored in the memory 104 or transmitted via the wireless module 106.

The sensor 114 is disposed within the mobile terminal 100 or within the first screen 130, examples of the sensor 114 include, but are not limited to: light sensor 114F, operational sensors, pressure sensor 114G, SAR sensor 114H, infrared heat sensors, distance sensors, gravitational acceleration sensors, and other sensors.

Among them, the pressure sensor 114G may detect a pressure generated by pressing on the mobile terminal 100. That is, the pressure sensor 114G detects pressure generated by contact or pressing between the user and the mobile terminal, for example, contact or pressing between the user's ear and the mobile terminal. Accordingly, the pressure sensor 114G may be used to determine whether contact or pressing has occurred between the user and the mobile terminal 100, as well as the magnitude of the pressure.

Referring to fig. 7 again, in the embodiment shown in fig. 7, the light sensor 114F and the pressure sensor 114G are disposed adjacent to the display panel 111. The light sensor 114F may turn off the display output by the processor 102 when an object is near the first screen 130, for example, when the mobile terminal 100 moves to the ear. The SAR sensor 114H detects a change in the peripheral capacitance, thereby determining whether a human body approaches the mobile terminal 100.

As one of the motion sensors, the gravity acceleration sensor can detect the magnitude of acceleration in various directions (generally three axes), detect the magnitude and direction of gravity when stationary, and can be used for applications (such as horizontal and vertical screen switching, related games, magnetometer attitude calibration), vibration recognition related functions (such as pedometer, tapping) and the like for recognizing the attitude of the mobile terminal 100. In addition, the mobile terminal 100 may also be configured with other sensors such as a gyroscope, a barometer, a hygrometer and a thermometer, which are not described herein,

Optionally, the touch screen 109 may include 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 detection device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 102, and can receive and execute commands sent by the processor 102. In addition, the touch detection function of the touch screen 109 may be implemented by using resistive, capacitive, infrared, and surface acoustic wave types. In addition to the touch screen 109, in other variations, the input module 118 may include other input devices, such as keys. The keys may include, for example, character keys for inputting characters, and control keys for triggering control functions. Examples of such control keys include a "back to home" key, a power on/off key, and the like.

The first screen 130 is used to display information input by a user, information provided to the user, and various graphic user interfaces of the mobile terminal 100, which may be composed of graphics, text, icons, numbers, videos, and any combination thereof, and in one example, the touch screen 109 may be disposed on the display panel 111 so as to be integrated with the display panel 111.
