Description

Technical Field

[0001] The present invention relates to the field of mobile terminal technology, and in particular to a terminal screen-off control method, device, mobile terminal and readable storage medium. Background Art

[0002] In order to save energy consumption of mobile terminals, when the screen of a mobile terminal is on, if there is no screen operation within a preset time, the screen of the mobile terminal will generally be turned off automatically. However, in some cases, for example, when a user needs to show the display content of a page, such as a document or a picture, to other people, if the viewing time is long and no screen operation is performed, the mobile terminal will automatically turn off the screen; at this time, if other people want to light up the screen of the mobile terminal again, the mobile terminal user needs to unlock it again. This process is very cumbersome and affects the efficiency of the use of the mobile terminal. In order to avoid the automatic screen turning off of the mobile terminal due to the long viewing time for others, you can set the system to extend the screen turning off time before showing the mobile terminal to others. However, the setting process is very cumbersome and directly affects the efficiency of the use of the mobile terminal.

[0017] The identity verification information includes facial image information and / or iris information.

[0018] Optionally, if the displayed content is not a preset type of content, the step of adjusting the target screen-off time to the sum of the current time and a first preset duration includes:

[0019] If the displayed content is not a preset type of content, obtaining the continuous screen-on time duration of the mobile terminal in a state where there is no screen operation;

[0020] Detecting whether the continuous screen-on duration is less than a second preset duration;

[0021] If the continuous screen-on time is less than the second preset time, the target screen-off time is adjusted to the sum of the current time and the first preset time.

[0022] Optionally, after the step of detecting whether the duration of the continuous screen-on time is less than a second preset time, the step further includes:

[0023] If the continuous screen-on time is greater than or equal to the second preset time, the mobile terminal is controlled to be in an unlocked screen-off state;

[0024] Detecting whether there is a preset screen-on operation within a third preset time period when the mobile terminal is in an unlocked screen-off state;

[0025] If it is detected that the mobile terminal is in an unlocked and screen-off state within a third preset time period and there is a preset screen-on operation, the screen of the mobile terminal is turned on.

[0026] Optionally, after the step of detecting whether there is a preset screen-on operation within a third preset time period when the mobile terminal is in an unlocked screen-off state, the step further includes:

When the terminal screen off control program is executed by a processor, the steps of the terminal screen off control method as described above are implemented.

[0038] A terminal screen-off control method proposed in an embodiment of the present invention detects whether the mobile terminal is in use before the mobile terminal automatically turns off the screen, and determines whether to turn off the screen based on whether the mobile terminal is in use. Thus, when the user is using the mobile terminal, the mobile terminal can automatically extend the screen-off time even if there is no screen operation for a long period of time. This avoids the problem that the mobile terminal automatically turns off the screen when there is no screen operation and affects the user's use of the mobile terminal. During the use of the mobile terminal, when there is no screen operation for a long period of time, the mobile terminal will not automatically turn off the screen, and there is no need to execute the process of unlocking the mobile terminal after turning off the screen, thereby improving the use efficiency of the mobile terminal.

For example, the terminal described in the present invention may include mobile terminals such as mobile phones, tablet computers, laptop computers, PDAs, portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers.

[0048] The following description will be made by taking a mobile terminal as an example, and those skilled in the art will appreciate that, in addition to components specifically used for mobile purposes, the configuration according to the embodiments of the present invention can also be applied to fixed-type terminals.

[0049] See also Figure 1 , which is a schematic diagram of the hardware structure of a mobile terminal for implementing various embodiments of the present invention, the mobile terminal 100 may include: RF (Radio Frequency, radio frequency) unit 101, WiFi module 102, audio output unit 103, A / V (audio / video) input unit 104, sensor 105, display unit 106, user input unit 107, interface unit 108, memory 109, processor 110, and power supply 111 and other components. Those skilled in the art can understand that Figure 1 The structure of the mobile terminal shown in the figure does not constitute a limitation on the mobile terminal. The mobile terminal may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0050] Combine the following Figure 1 The following is a detailed introduction to the various components of the mobile terminal:

[0051] The radio frequency unit 101 can be used for receiving and sending signals during information transmission or communication. Specifically, after receiving the downlink information of the base station, it is sent to the processor 110 for processing; in addition, the uplink data is sent to the base station. Generally, the radio frequency unit 101 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, etc. In addition, the radio frequency unit 101 can also communicate with the network and other devices through wireless communication. The above-mentioned wireless communication can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution) and TDD-LTE (Time Division Duplexing-Long Term Evolution), etc.

[0052] WiFi is a short-range wireless transmission technology. Mobile terminals can help users send and receive emails, browse web pages, and access streaming media through WiFi module 102. It provides users with wireless broadband Internet access. Figure 1 The WiFi module 102 is shown, but it is understandable that it is not an essential component of the mobile terminal and can be omitted as needed without changing the essence of the invention.

[0053] The audio output unit 103 can convert the audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, etc. Moreover, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (for example, a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, etc.

[0054] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processor (GPU) 1041 and a microphone 1042, and the graphics processor 1041 processes the image data of a static picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The processed image frame can be displayed on the display unit 106. The image frame processed by the graphics processor 1041 can be stored in the memory 109 (or other storage medium) or sent via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) via the microphone 1042 in a telephone call mode, a recording mode, a voice recognition mode, and other operating modes, and can process such sound into audio data. The processed audio (voice) data can be converted into a format output that can be sent to a mobile communication base station via the radio frequency unit 101 in the case of a telephone call mode. The microphone 1042 can implement various types of noise elimination (or suppression) algorithms to eliminate (or suppress) noise or interference generated in the process of receiving and sending audio signals.

[0055] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor includes an ambient light sensor and a proximity sensor, wherein the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can also be configured on the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0056] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0057] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile terminal. Specifically, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 1071 or near the touch panel 1071 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute the command sent by the processor 110. In addition, the touch panel 1071 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch panel 1071, the user input unit 107 may also include other input devices 1072. Specifically, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, a function key (such as a volume control key, a switch key, etc.), a trackball, a mouse, a joystick, etc., which are not specifically limited here.

[0058] Furthermore, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of the touch event. Then, the processor 110 provides a corresponding visual output on the display panel 1061 according to the type of the touch event. Figure 1 In the figure, the touch panel 1071 and the display panel 1061 are used as two independent components to implement the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to implement the input and output functions of the mobile terminal, which is not limited here.

[0059] The interface unit 108 serves as an interface through which at least one external device can be connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, etc. The interface unit 108 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal 100 and an external device.

[0060] The memory 109 can be used to store software programs and various data. The memory 109 can be a computer storage medium, and the memory 109 stores the terminal screen off control program of the present invention. The memory 109 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, phone book, etc.), etc. In addition, the memory 109 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0061] The processor 110 is the control center of the mobile terminal, and uses various interfaces and lines to connect various parts of the entire mobile terminal. By running or executing software programs and / or modules stored in the memory 109, and calling data stored in the memory 109, the processor 110 performs various functions of the mobile terminal and processes data, thereby monitoring the mobile terminal as a whole. For example, the processor 110 executes the terminal screen off control program in the memory 109 to implement the steps of each embodiment of the terminal screen off control method of the present invention.

[0062] The processor 110 may include one or more processing units; optionally, the processor 110 may integrate an application processor and a modem processor, wherein the application processor mainly processes an operating system, a user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the modem processor may not be integrated into the processor 110.

[0063] The mobile terminal 100 may further include a power supply 111 (such as a battery) for supplying power to various components. Optionally, the power supply 111 may be logically connected to the processor 110 via a power management system, thereby implementing functions such as managing charging, discharging, and power consumption management through the power management system.

[0064] although Figure 1 Not shown, the mobile terminal 100 may further include a Bluetooth module, etc., which will not be described in detail here.

[0065] To facilitate understanding of the embodiments of the present invention, the communication network system on which the mobile terminal of the present invention is based is described below.

[0066] See also Figure 2 , Figure 2A communication network system architecture diagram is provided for an embodiment of the present invention. The communication network system is an LTE system of universal mobile communication technology. The LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203 and an operator's IP service 204, which are sequentially connected for communication.

[0067] Specifically, UE201 may be the above-mentioned terminal 100, which will not be described in detail here.

[0068] E-UTRAN 202 includes eNodeB 2021 and other eNodeBs 2022 , etc. Among them, eNodeB 2021 can be connected to other eNodeBs 2022 through a backhaul (eg, an X2 interface), and eNodeB 2021 is connected to EPC 203 , and eNodeB 2021 can provide UE 201 with access to EPC 203 .

[0069] EPC203 may include MME (Mobility Management Entity) 2031, HSS (Home Subscriber Server) 2032, other MMEs 2033, SGW (Serving Gate Way) 2034, PGW (PDN Gate Way) 2035 and PCRF (Policy and Charging Rules Function) 2036, etc. Among them, MME2031 is a control node that processes signaling between UE201 and EPC203, and provides bearer and connection management. HSS2032 is used to provide some registers to manage functions such as home location register (not shown in the figure), and save some user-specific information such as service features and data rates. All user data can be sent through SGW2034, PGW2035 can provide IP address allocation and other functions for UE 201, PCRF2036 is the policy and charging control policy decision point for service data flow and IP bearer resources, which selects and provides available policy and charging control decisions for the policy and charging execution function unit (not shown in the figure).

[0070] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem) or other IP services.

[0071] Although the above introduction takes the LTE system as an example, those skilled in the art should know that the present invention is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA and future new network systems, etc., which are not limited here.

[0072] Based on the above mobile terminal hardware structure and communication network system, various embodiments of the method of the present invention are proposed.

[0073] Reference Figure 3 In the first embodiment of the terminal screen off control method of the present invention, the terminal screen off control method includes:

[0074] Step S10, when it is detected that the mobile terminal is in the screen-on state, obtaining the time interval between the target screen-off time of the mobile terminal and the current time;

[0075] In the embodiment of the present invention, the mobile terminal is used as the execution subject. In order to save energy consumption of the mobile terminal, when the screen of the mobile terminal is on, if there is no screen operation within a preset time, the screen of the mobile terminal is generally turned off automatically.

[0076] Reference Figure 4 , Figure 4 The figure is a schematic diagram of a scene in which a document is being displayed on a mobile terminal screen. In some cases, for example, when a mobile terminal user shows a document or picture on a mobile terminal to others for viewing, if others view the document or picture for a long time and there is no screen operation within a preset time, the mobile terminal automatically turns off the screen, which will affect others' viewing of the document or picture; if others want to light up the mobile terminal screen, the mobile terminal user needs to unlock it again, which is very cumbersome and affects the efficiency of using the mobile terminal. For another example, when a user is viewing a document or picture, although there is no screen operation within a preset time, the user is still using the mobile terminal. If the mobile terminal automatically turns off the screen, it will affect the user's use of the mobile terminal. Although the user can re-unlock and light up the mobile terminal screen to continue using the terminal, the re-unlocking operation is cumbersome and will affect the efficiency of using the mobile terminal. The present invention provides a terminal screen-off control method, so that a mobile terminal can determine whether to turn off the screen according to whether the user is using the mobile terminal, so that when the user is using the mobile terminal, even if there is no screen operation for a long period of time, the mobile terminal can automatically extend the screen-off time.

[0077] Mobile terminals generally set an automatic screen-off duration. After the mobile terminal turns on the screen, if there is no screen operation on the mobile terminal within the automatic screen-off duration, the mobile terminal will automatically turn off the screen and lock it. In this embodiment, when it is detected that the mobile terminal is in the screen-on state, the target screen-off time of the mobile terminal is determined according to the automatic screen-off time of the mobile terminal and the screen operation of the mobile terminal, and the current time is obtained. Then, the difference between the current time and the target screen-off time of the mobile terminal is calculated as the time interval between the target screen-off time of the mobile terminal and the current time. Among them, the target screen-off time refers to the time point when the mobile terminal automatically turns off the screen and locks. The current time refers to the time point of the mobile terminal at the current moment. The time interval refers to the interval between the target screen-off time of the mobile terminal and the current time, which is obtained by the difference between the current time and the target screen-off time of the mobile terminal.

[0078] For ease of understanding, a specific example is used for illustration. For example, the automatic screen off time of the mobile terminal is 5 minutes, the preset time threshold is 1 minute, the mobile terminal detects a screen operation at 12:00, and no screen operation is detected until the current time 12:04, then the target screen off time is 12:05, and the time interval is 1 minute.

[0079] Step S20, when it is detected that the time interval is less than or equal to the preset time threshold, detecting whether the mobile terminal is in use;

[0080] Specifically, detect whether the time interval is less than or equal to a preset time threshold. If the time interval is detected to be less than or equal to the preset time threshold, detect whether the mobile terminal is in use. Specifically, one implementation is to detect whether there is a face image within a preset range in front of the mobile terminal screen through the camera of the mobile terminal. If a face image is detected within the preset range in front of the mobile terminal screen, it is determined that the mobile terminal is in use; if it is detected that there is no face image within the preset range in front of the mobile terminal screen, it is determined that the mobile terminal is not in use. One implementation is to detect whether there is iris information within the preset range in front of the mobile terminal screen. If iris information is detected within the preset range in front of the mobile terminal screen, it is determined that the mobile terminal is in use; if it is detected that there is no iris information within the preset range in front of the mobile terminal screen, it is determined that the mobile terminal is not in use.

[0081] If the detected time interval is greater than the preset time threshold, the mobile terminal does not detect whether the mobile terminal is in use. The preset time threshold refers to the time threshold used to determine whether to detect whether the mobile terminal is in use. The preset time threshold can be set according to specific needs. In the embodiment of the present invention, there is no restriction on the value of the preset time threshold. The use state refers to the state in which the mobile terminal is in a state where the screen is on and viewed by the user, that is, when the screen of the mobile terminal is on, the user is staring at the screen of the mobile terminal.

[0082] Step S30: If the mobile terminal is in use, the target screen-off time is adjusted to the sum of the current time and the first preset duration, and the mobile terminal is controlled to turn off the screen according to the adjusted target screen-off time.

[0083] If the mobile terminal is in use, at this time, it is necessary to extend the screen-off time of the mobile terminal to prevent the mobile terminal from automatically turning off the screen and affecting the user's use of the mobile terminal. Specifically, the sum of the current time and the first preset duration is calculated to obtain the screen-off time, and the target screen-off time of the mobile terminal is adjusted to the screen-off time. When it is detected that the current time is the adjusted target screen-off time, that is, when it is detected that the current time is the screen-off time, the mobile terminal is controlled to turn off the screen. Among them, the first preset duration can be set according to specific needs, and the specific duration value of the first preset duration is not limited in the embodiment of the present invention.

[0084] If the mobile terminal is not in use, the target screen-off time is not adjusted; and if no screen operation is detected until the target screen-off time, the mobile terminal automatically turns off the screen.

[0085] In the present embodiment, before the mobile terminal automatically turns off the screen, it detects whether the mobile terminal is in use and determines whether to turn off the screen based on whether the mobile terminal is in use. Thus, when the user is using the mobile terminal, the mobile terminal can automatically extend the screen-off time even if there is no screen operation for a long period of time. This avoids the problem that when there is no screen operation on the mobile terminal, the screen of the mobile terminal is automatically turned off, thus affecting the user's use of the mobile terminal. During the use of the mobile terminal, when there is no screen operation on the mobile terminal for a long period of time, the mobile terminal will not automatically turn off the screen, and there is no need to execute the process of unlocking the mobile terminal after turning off the screen, thereby improving the use efficiency of the mobile terminal.

[0086] Optionally, based on the above first embodiment, a second embodiment of the terminal screen off control method of the present invention is proposed, wherein if the displayed content is not a preset type of content, the step of adjusting the target screen off time to the sum of the current time and the first preset duration includes:

[0087] Step A1, if the mobile terminal is in use, detecting whether the user of the mobile terminal is a preset object;

[0088] Furthermore, in the present embodiment, in order to avoid the situation where the mobile terminal is used by someone other than the mobile terminal user, automatically extending the screen-off time would cause the personal privacy of the mobile terminal user to be leaked, if it is detected that the mobile terminal is used by someone other than the mobile terminal user, the screen-off time of the mobile terminal will be automatically extended only when the content displayed on the mobile terminal is a preset type of content.

[0089] Specifically, if the mobile terminal is in use, first, it is detected whether the user of the mobile terminal is a preset object. One implementation method is to obtain the facial information of the user of the mobile terminal and the facial information of the preset object, and compare the facial information of the user of the mobile terminal with the facial information of the preset object to determine whether the facial information of the user of the mobile terminal matches the facial information of the preset object. If the facial information of the user of the mobile terminal matches the facial information of the preset object, it is determined that the user of the mobile terminal is the preset object; if the facial information of the user of the mobile terminal does not match the facial information of the preset object, it is determined that the user of the mobile terminal is not the preset object.

[0090] One implementation is to obtain iris information of a user of the mobile terminal and iris information of a preset object, and compare the iris information of the user of the mobile terminal with the iris information of the preset object to determine whether the iris information of the user of the mobile terminal matches the iris information of the preset object. If the iris information of the user of the mobile terminal matches the iris information of the preset object, it is determined that the user of the mobile terminal is the preset object; if the iris information of the user of the mobile terminal does not match the iris information of the preset object, it is determined that the user of the mobile terminal is not the preset object. There can be many specific implementations for detecting whether the user of the mobile terminal is the preset object, which will not be listed one by one here.

[0091] The preset object refers to a user who has the right to use the mobile terminal, for example, the mobile terminal user himself, and the number of preset objects can be set according to specific needs. The user object refers to a user who is using the mobile terminal, which can be the mobile terminal user himself or not.

[0092] Optionally, the step of detecting whether the object to be used is a preset object includes:

[0093] Obtaining identity authentication information of the user object, and detecting whether the identity authentication information is preset information;

[0094] If the identity verification information is preset information, determining that the user object is a preset object;

[0095] If the identity verification information is not the preset information, determining that the user object is not the preset object;

[0096] The identity verification information at least includes facial image information and / or iris information.

[0097] Specifically, one implementation method is to obtain verification information (identity verification information of the user object) that can be used to detect the identity of the user object, such as obtaining only the face information of the user object or only the iris information of the user object, and obtaining preset information corresponding to the identity verification information type, and compare the identity verification information of the user object with the preset information to detect whether the identity verification information of the user object is consistent with the preset information. If the identity verification information of the user object is consistent with the preset information, it is determined that the identity verification information of the user object is the preset information and the user object is the preset object; if the identity verification information of the user object is inconsistent with the preset information, it is determined that the identity verification information of the user object is not the preset information and the user object is not the preset object.

[0098] One implementation method is to obtain multiple verification information (identity verification information of the user) that can be used to detect the identity of the user, such as simultaneously obtaining the face information and iris information of the user, and obtaining each preset information corresponding to each verification information type, and comparing each verification information with the preset information corresponding to the type, to detect whether each verification information is consistent with the preset information corresponding to the type. If each verification information is consistent with the preset information corresponding to the type, it is determined that the identity verification information of the user is the preset information, and the user is the preset object; if one verification information is inconsistent with the preset information corresponding to the type, it is determined that the identity verification information of the user is not the preset information, and the user is not the preset object.

[0099] Among them, identity verification information refers to verification information used to identify the identity of the user, specifically verification information used to identify whether the user is the preset object, such as facial image information, iris information, etc. Preset information refers to verification information of the identity of the user who has the right to use the mobile terminal, such as facial image information, iris information, etc. The type of information contained in the identity verification information and the type of information contained in the preset information should be consistent. For example, if the preset information is facial image information, the identity verification information should include facial image information; if the preset information is iris information, the identity verification information should include iris information; if the preset information is facial image information and iris information, the identity verification information should include at least one of facial image information or iris information.

[0100] In this embodiment, by obtaining the identity authentication information and preset information of the user object, and comparing the identity authentication information of the user object with the preset information, if the identity authentication information of the user object does not match the preset information, it is determined that the user object is not the preset object, thereby accurately judging whether the user object is the preset object, and providing accurate data for subsequent judgment whether to detect whether the displayed content of the current page of the mobile terminal is the preset type of content.

[0101] Step A2: if the user object is not a preset object, detecting whether the displayed content of the current page of the mobile terminal is a preset type of content;

[0102] If the user is not the preset object, it proves that the user is not the mobile terminal user himself. In order to avoid the privacy leakage of the mobile terminal user himself, it is necessary to determine whether to extend the screen off time of the mobile terminal based on whether the displayed content of the current page of the mobile terminal is private content. Specifically, when it is detected that the user is not the preset object, first, the displayed content of the current page of the mobile terminal is obtained, and then it is detected whether the displayed content of the current page of the mobile terminal is a preset type of content. Among them, the preset type of content refers to the content that is private information for the mobile terminal user himself, and the preset type of content can be set by the mobile terminal user himself according to specific needs.

[0103] If the user object is a preset object, it proves that the user object is the mobile terminal user himself, and the mobile terminal user himself is using the mobile terminal, and the target screen-off time of the mobile terminal is adjusted to the sum of the current time and the first preset duration.

[0104] Step A3: If the displayed content is not a preset type of content, the target screen off time is adjusted to the sum of the current time and the first preset duration.

[0105] If it is detected that the display content of the current page of the mobile terminal is not the preset type of content, it proves that the display content of the current page of the mobile terminal is not private content, and the mobile terminal is in use. At this time, it is necessary to extend the screen-off time of the mobile terminal; specifically, calculate the sum of the current time and the first preset duration to obtain the screen-off time, and adjust the target screen-off time of the mobile terminal to the screen-off time.

[0106] If it is detected that the display content of the current page of the mobile terminal is a preset type of content, it proves that the display content of the current page of the mobile terminal is private content, and the mobile terminal is in use. At this time, the target screen-off time is not adjusted, and the mobile terminal automatically turns off the screen at the target screen-off time to avoid the mobile terminal being in the screen-on state for a long time, which may easily lead to the leakage of the mobile terminal user's personal information.

[0107] In this embodiment, when the object being used is not a preset object, it is detected whether the display content of the current page of the mobile terminal is a preset type of content to determine whether the target screen-off time needs to be extended. If the display content of the current page of the mobile terminal is not a preset type of content, that is, the display content of the current page of the terminal is not private content, the target screen-off time is adjusted to be extended, thereby avoiding the problem that the mobile terminal is in the screen-on state for a long time, which may easily lead to the leakage of the mobile terminal user's personal information.

[0108] Optionally, based on the above second embodiment, a third embodiment of the terminal screen off control method of the present invention is proposed, and step A3 includes:

[0109] Step B1, if the displayed content is not a preset type of content, obtaining the continuous screen-on time duration of the mobile terminal in a state where there is no screen operation;

[0110] In order to avoid the detection of the mobile terminal being in use all the time, which results in the infinite adjustment of the target screen-off time (i.e., the infinite extension of the screen-off time) and causes excessive mobile terminal loss, in this embodiment, the continuous screen-on time of the mobile terminal in the state of no screen operation is detected to determine whether to adjust the target screen-off time (i.e., extend the screen-off time). If it is detected that the continuous screen-on time of the mobile terminal in the state of no screen operation exceeds the preset time, the screen-off time is not extended; if it is detected that the continuous screen-on time of the mobile terminal in the state of no screen operation does not exceed the preset time, the screen-off time is extended. Specifically, if it is detected that the display content of the current page of the terminal is not the preset type of content, it proves that the display content of the current page of the mobile terminal is not private content, and the mobile terminal is in use. At this time, it is necessary to extend the screen-off time of the mobile terminal; first, the continuous screen-on time of the mobile terminal in the state of no screen operation is obtained. The continuous screen-on time refers to the screen-on time from the last time the mobile terminal detects the screen operation until the current time point.

[0111] Step B2, detecting whether the duration of the continuous screen on is less than a second preset duration;

[0112] Specifically, the second preset duration is obtained, the duration of the continuous screen on when the mobile terminal does not have a screen operation is detected, and it is determined whether the duration of the continuous screen on when the mobile terminal does not have a screen operation is less than the second preset duration. The second preset duration refers to a specific continuous screen on duration used to determine whether to adjust the target screen off time. If the continuous screen on duration is less than the second preset duration, the target screen off time is adjusted; if the continuous screen on duration is greater than or equal to the second preset duration, the target screen off time is not adjusted; the second preset duration can be set according to specific needs, and there is no restriction on the value of the second preset duration in the embodiment of the present invention.

[0113] Step B3, if the continuous screen-on time is less than the second preset time, the target screen-off time is adjusted to the sum of the current time and the first preset time.

[0114] If it is detected that the continuous screen-on time is less than the second preset time, it proves that the continuous screen-on time of the mobile terminal in the non-screen operation state is not too long. At this time, it is necessary to extend the screen-off time of the mobile terminal; specifically, calculate the sum of the current time and the first preset time to obtain the screen-off time, and adjust the target screen-off time of the mobile terminal to the screen-off time.

[0115] If it is detected that the continuous screen-on time is greater than or equal to the second preset time, it proves that the continuous screen-on time of the mobile terminal when there is no screen operation is too long. At this time, if the screen-off time is further extended, it will cause excessive damage to the mobile terminal. Therefore, when the continuous screen-on time is greater than or equal to the second preset time, the screen-off time of the mobile terminal will not be extended, that is, the target screen-off time will not be adjusted.

[0116] In this embodiment, whether to adjust the target screen-off time (i.e., extend the screen-off time) is determined by detecting the continuous screen-on time when the mobile terminal has no screen operation. The target screen-off time is adjusted only when it is detected that the continuous screen-on time is less than a second preset time. This avoids detecting that the mobile terminal is in use for a long time, which results in an infinite loop of adjusting the target screen-off time (i.e., extending the screen-off time) and causing excessive mobile terminal loss.

[0117] Optionally, based on the third embodiment above, a fourth embodiment of the terminal screen off control method of the present invention is proposed, and after step B2, the following further includes:

[0118] Step C1, if the continuous screen-on time is greater than or equal to a second preset time, controlling the mobile terminal to be in an unlocked screen-off state;

[0119] If the continuous screen-on time is greater than or equal to the second preset time, it proves that the continuous screen-on time of the mobile terminal in the state of no screen operation is too long. At this time, if the screen-off time is continued to be extended, it will cause excessive mobile terminal loss. Therefore, when the continuous screen-on time is greater than or equal to the second preset time, the screen-off time of the mobile terminal will not be extended, that is, the target screen-off time will not be adjusted. And the mobile terminal is controlled to enter the unlocked screen-off state, so that when the user obtains the operation of lighting up the mobile terminal screen again, there is no need to execute the process of unlocking the mobile terminal, thereby improving the use efficiency of the mobile terminal. If the continuous screen-on time is less than the second preset time, the target screen-off time of the mobile terminal is adjusted. Among them, the unlocked screen-off state means that the mobile terminal is in the screen-off state, but the mobile terminal is in the unlocked state. If the screen-on operation of the mobile terminal is detected in the unlocked screen-off state, the mobile terminal will enter the interface just before the screen is turned off.

[0120] Step C2, detecting whether there is a preset screen-on operation within a third preset time period when the mobile terminal is in an unlocked screen-off state;

[0121] Specifically, the third preset duration is obtained, the duration of the mobile terminal being in the unlocked screen-off state is detected, and it is determined whether there is a preset screen-on operation for lighting up the mobile terminal screen during the period when the duration of the mobile terminal being in the unlocked screen-off state is less than or equal to the third preset duration. The preset screen-on operation refers to the operation of lighting up the mobile terminal screen, and the preset screen-on operation can be implemented in a variety of ways, such as clicking the mobile terminal screen, clicking the power button of the mobile terminal, etc.; the specific implementation method of the preset screen-on operation can be set according to specific needs. In this embodiment, the specific implementation method of the preset screen-on operation is not limited.

[0122] Step C3: If it is detected that the mobile terminal is in an unlocked screen-off state within a third preset time period and there is a preset screen-on operation, the screen of the mobile terminal is turned on.

[0123] If it is detected that the mobile terminal is in an unlocked screen-off state for a duration less than or equal to a third preset duration, and there is a preset screen-on operation to light up the screen of the mobile terminal, it is proved that the user still needs to continue to use the mobile terminal, and the screen of the mobile terminal needs to be lit. Specifically, if it is detected that the mobile terminal is in an unlocked screen-off state for a third preset duration, and there is a preset screen-on operation, the screen of the mobile terminal is lit, and the mobile terminal is controlled to enter the interface just before the screen is turned off.

[0124] If it is detected that the mobile terminal is in an unlocked and screen-off state for a period that is less than or equal to a third preset period, and there is no preset screen-lighting operation to light up the screen of the mobile terminal, that is, the mobile terminal is in the unlocked and screen-off state for the third preset period, and there is no preset screen-lighting operation, then the mobile terminal is locked to prevent the mobile terminal from being in the unlocked and screen-off state all the time, which causes energy consumption of the mobile terminal and makes the mobile terminal information easily leaked.

[0125] In this embodiment, when the continuous screen-on time is greater than or equal to the second preset time, that is, when the continuous screen-on time of the mobile terminal in the state of no screen operation is too long, the screen-off time of the mobile terminal is not extended, and the mobile terminal is controlled to be in an unlocked screen-off state to avoid excessive mobile terminal loss caused by further extending the screen-off time. In addition, by controlling the mobile terminal to be in an unlocked screen-off state, when the user obtains the operation of lighting up the mobile terminal screen again, the mobile terminal can be controlled to enter the interface just before the mobile terminal screen is turned off without performing the process of unlocking the mobile terminal, thereby improving the use efficiency of the mobile terminal.

[0126] Optionally, step C2 further includes:

[0127] If it is detected that the mobile terminal is in an unlocked and screen-off state for a third preset time period and there is no preset screen-on operation, the mobile terminal is locked.

[0128] If it is detected that the mobile terminal is in an unlocked, screen-off state for a period less than or equal to a third preset period, and there is no preset screen-on operation to light up the screen of the mobile terminal, the mobile terminal is locked to prevent the mobile terminal from being in an unlocked, screen-off state all the time, which causes energy consumption of the mobile terminal and makes the mobile terminal information easily leaked.

[0129] If it is detected that the mobile terminal is in an unlocked screen-off state within a third preset time period and there is a preset screen-on operation, the mobile terminal screen is lit and the mobile terminal is controlled to enter the interface of the mobile terminal just before the screen was turned off.

[0130] Optionally, based on the third embodiment above, a fifth embodiment of the terminal screen off control method of the present invention is proposed, wherein after the step of detecting whether the user object is a preset object, the step further includes:

[0131] Step D1, if the user object is not a preset object, detecting whether there is a page switching operation in the mobile terminal;

[0132] If the user is not the preset user, it means that the user who is not authorized to use the mobile terminal is using the mobile terminal, and there is a risk of information leakage on the mobile terminal. At this time, the mobile terminal is detected to see if there is a page switching operation. The page switching operation refers to the operation of switching the current display page of the mobile terminal, for example, switching from document reading mode to chat software.

[0133] If the user object is a preset object, it proves that the user who has the use authority of the mobile terminal is using the mobile terminal, and there is no risk of information leakage on the mobile terminal. At this time, it is not detected whether there is a page switching operation on the mobile terminal.

[0134] Step D2, if the mobile terminal performs the page switching operation, detecting whether the page content displayed after the mobile terminal performs the page switching operation is private content;

[0135] If there is a page switching operation on the mobile terminal, and the user who is using the mobile terminal is not a user with permission to use the mobile terminal, it proves that the risk of information leakage on the mobile terminal is further increased. At this time, the page content of the page displayed after the mobile terminal performs the page switching operation is obtained, and it is determined whether the page content of the page displayed after the mobile terminal performs the page switching operation is private content. Among them, private content refers to content that will cause losses to the mobile terminal user if it is leaked; or content that the mobile terminal user does not want to be viewed by others; private content can be set according to specific needs, and the type of private content is not limited in this embodiment.

[0136] If there is no page switching operation on the mobile terminal, the risk of information leakage on the mobile terminal is not further increased, and there is no need to further obtain and determine the page content of the page displayed after the mobile terminal performs the page switching operation.

[0137] Step D3: If the page content is private content, control the mobile terminal to enter a screen-off and locked state.

[0138] If it is detected that the page content of the displayed page after the mobile terminal performs a page switching operation is private content, the mobile terminal is controlled to enter a screen-off lock state to avoid the risk of information leakage of the mobile terminal. If it is detected that the page content of the displayed page after the mobile terminal performs a page switching operation is not private content, the automatic screen-off time of the mobile terminal can be further shortened.

[0139] For ease of understanding, a specific embodiment is used for illustration. Referring to and 5, Figure 5 A schematic diagram of a scenario in which the display state of a mobile terminal screen changes before and after a page switching operation is obtained. For example, the page content currently displayed by the mobile terminal is a preset type of content. When a page switching operation is obtained, it is detected whether the page content displayed after the mobile terminal performs the page switching operation is private content. At this time, the mobile terminal is controlled to enter a screen-off locked state, that is, the mobile terminal enters a screen-off state, and the mobile terminal is locked, and it needs to be unlocked again to enter the mobile terminal display page.

[0140] In this embodiment, if the user object is not a preset object and the display content of the mobile terminal is switched to private content, the risk of information leakage of the mobile terminal is avoided by controlling the mobile terminal to enter a screen-off locked state.
