In order to facilitate understanding of the embodiments of the present invention, a communication network system on which the mobile terminal of the present invention is based is described below.

Referring to fig. 2, fig. 2 is an architecture diagram of a communication Network system according to an embodiment of the present invention, where the communication Network system is an LTE system of a universal mobile telecommunications technology, and 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 IP service 204 of an operator, which are in communication connection in sequence.

The E-UTRAN202 includes eNodeB2021 and other eNodeBs 2022, among others. Among them, the eNodeB2021 may be connected with other eNodeB2022 through backhaul (e.g., X2 interface), the eNodeB2021 is connected to the EPC203, and the eNodeB2021 may provide the UE201 access to the EPC 203.

Although the LTE system is described as an example, it should be understood by those skilled in the art that the present invention is not limited to the LTE system, but may also be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems.

Based on the above hardware structure of the mobile terminal 100 and the communication network system, various embodiments of the screen state control method of the present invention are proposed.

In the present embodiment, an embodiment of a screen state control method is provided, and it should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that here.

In the embodiment of the present invention, the screen state control method is optionally applied to the mobile terminal 100.

Referring to fig. 3 and 4, the body 200 of the mobile terminal 100 includes an outer case 210 and various hardware inside the outer case 210. One side of the outer casing 210 is provided with a screen, the other side opposite to the screen is a back, and the outer casing 210 connecting the screen and the back is a side of the mobile terminal 100. Generally, the mobile terminal 100 has two long sides and two short sides.

The housing 210 is provided with a hand-held state detection area 220 for detecting whether the mobile terminal 100 is in a hand-held state. The hand-held state detection area 220 may cover the entire outer casing 210, or may be only a partial area of the outer casing 210, and the area and the position of the area may be flexibly configured according to actual needs.

In order to sense an object, a capacitive sensor 230 is disposed on the hand-held state detection area 220. The capacitive sensor 230 is electrically connected to the CPU300, and transmits the capacitance value to the CPU300 in real time, so that the CPU300 can determine whether an object touches the hand-held state detection area 220.

The body 200 is provided with an attitude sensor 400 for sensing an attitude change of the mobile terminal 100 in a hand-held state. The posture acquiring instrument 400 is electrically connected to the CPU300, and transmits a signal generated by the same to the CPU 300.

The CPU300 is electrically connected to the capacitance sensor 230 and the posture collection instrument 400, respectively, and receives signals transmitted from the capacitance sensor 230 and the posture collection instrument 400. The CPU300 may detect whether an object touches the hand-held state detection area 220 according to the signal transmitted from the capacitive sensor 230.

The working principle of the capacitive sensor 230 is: assuming that the effective projection area of a proximity object (e.g., a user's finger) in the capacitive sensor 230 is a, the capacitance value C can be expressed by the following formula:

it should be noted that, in the following description,₀and_rwhich represent the dielectric constants of vacuum and air, respectively, and d represents the distance between the approaching object and the capacitive sensor 230. As can be seen from the formula, the effective projection area a and the distance d from the object can both change the value of the capacitor C, so that the interaction state between the user and the mobile terminal 100 can be determined according to the change of the capacitor C and the difference between the capacitors, and further, whether the mobile terminal 100 is in the hand-held state can be detected. Further, the pressure value of the hand can be detected.

It should be noted that, in addition to using the capacitance sensor 230 to detect whether the mobile terminal 100 is in the hand-held state, a pressure sensor, a photosensitive sensor, etc. may also be used to detect whether the mobile terminal 100 is in the hand-held state.

Thus, the CPU300 can determine whether or not an object touches the hand-held state detection area 220 according to the magnitude and the variation trend of the capacitance value fed back by the capacitance sensor 230. Generally, when the user approaches the capacitive sensor 230, the capacitance value fed back by the capacitive sensor 230 gradually increases. Considering that grip strength of different users is different, a capacitance threshold value may be preset, and when the capacitance value detected by the capacitive sensor 230 gradually increases and exceeds the preset capacitance threshold value, it is determined that an object is in contact with the position where the capacitive sensor 230 is located.

Then, the CPU300 detects whether the mobile terminal 100 is in a hand-held state according to the position touched by the object sensed by the capacitive sensor 230. For example, when a user holds the mobile terminal 100 with one hand, it is common that four fingers contact one long side of the mobile terminal 100 and a palm contacts the other long side of the mobile terminal 100. If the position touched by the object sensed by the capacitive sensor 230 includes two long sides of the mobile terminal 100, it may be determined that the mobile terminal 100 is currently in a hand-held state.

After determining that the mobile terminal 100 is currently in the hand-held state, the CPU300 generates an angle between the mobile terminal 100 and the horizontal direction according to the signal transmitted by the gesture acquirer 400, and further, the CPU300 determines an angle change direction of the mobile terminal 100 according to the signal transmitted by the gesture acquirer 400, thereby detecting a gesture change of the mobile terminal 100. Herein, the angle between the body 200 and the horizontal direction may be understood as a value of an inclination angle of the body 200 of the mobile terminal 100 with respect to the horizontal direction, and the direction of the change of the angle of the mobile terminal 100 may be understood as an inclination direction of the body 200 of the mobile terminal 100 with respect to the horizontal direction, which represents the change of the direction of the body 200.

The gesture acquirer 400 may be a gyroscope, a gravity sensor, or other devices for detecting the angle change of the mobile terminal 100 from the horizontal direction. The gyroscope operates on the principle that the rotating shaft of the object rotates at a high speed, and tends to the vertical direction under the action of an external force for changing the direction of the rotating shaft, and when the rotating object tilts transversely, gravity acts in the direction for increasing the tilt, and the rotating shaft moves in the vertical direction, so that the motion (motion of the camera) for shaking the head is generated, and the CPU300 can calculate the tilt direction and the tilt angle of the mobile terminal 100 relative to the horizontal direction according to the signal generated by the rotation of the gyroscope.

When detecting the change in the angle of the mobile terminal 100 from the horizontal direction using the gravity sensor, the acceleration due to gravity is measured by the gravity sensor and a signal is transmitted to the CPU300, and the CPU300 calculates the tilt direction (angle change direction) and tilt angle (angle of the mobile terminal 100 from the horizontal direction) of the mobile terminal 100 from the acceleration measured by the gravity sensor.

Here, the horizontal direction may be understood as a reference direction that is set as a reference vector value set by the CPU300 for reference, the reference vector value being a vector value designated by the mobile terminal 100 in a preset azimuth coordinate system or a vector value of an initial position of the mobile terminal 100 to be acquired from a sensor. The preset orientation coordinate system comprises one or more of a plane coordinate system, a terrestrial coordinate system and a geographic coordinate system. The initial position of the mobile terminal 100 may be a position when the mobile terminal 100 enters the current operation mode, or a position of the mobile terminal 100 before a preset time interval, or a position after the CPU300 executes the control instruction last time, and may be flexibly configured or selected according to actual needs.

The CPU300 periodically detects an angle between the body 200 and the horizontal direction according to a preset frequency, or monitors an angle between the body 200 and the horizontal direction in real time. The CPU300 controls the mobile terminal 100 when an angle between the body 200 and the horizontal direction satisfies a preset control condition. Specifically, the CPU300 searches the control condition library for a control condition that is satisfied by an angle of the mobile terminal 100 with respect to the horizontal direction, determines a control instruction corresponding to the control condition, and after determining the control instruction, the CPU300 executes the control instruction to correspondingly control the mobile terminal 100.

In one embodiment, the predetermined control conditions include, but are not limited to, a predetermined direction, and a range of angular values. When it is required to be described, the preset control condition may be configured by the CPU300, or may be set by the user, or the use habit of the user may be collected to perform optimization adjustment on the range of the direction and the angle value in the control condition.

Referring to fig. 5, the screen status control method includes:

in step S10, when the mobile terminal 100 is in the black screen state, an angle of the mobile terminal 100 with respect to a horizontal direction is detected, and whether the mobile terminal 100 is in a hand-held state is detected by a sensor.

In this embodiment, at least one sensor is disposed on each of the left and right sides of the mobile terminal 100, and the mobile terminal 100 detects whether it is in a hand-held state through the sensor. One sensor may be provided on each of the left and right sides of the mobile terminal 100, or a plurality of sensors may be provided. Specifically, referring to fig. 6, fig. 7a, fig. 7b and fig. 7c, fig. 6 is a schematic diagram illustrating that one sensor is respectively disposed on the left and right sides of the mobile terminal 100 in an embodiment of the present invention, fig. 7a is a schematic diagram illustrating that a plurality of sensors are respectively disposed on the left and right sides of the mobile terminal 100 in an embodiment of the present invention, fig. 7b is a right side view of the front of the mobile terminal in fig. 7a in the present invention, and fig. 7c is a left side view of the front of the mobile terminal in fig. 7. In fig. 6, S1 denotes a sensor on the right side of the mobile terminal 100, and S2 denotes a sensor on the left side of the mobile terminal 100; in fig. 7a, 7b and 7c, a plurality of sensors are provided at positions of S1 and S2 in fig. 6, so that S1 is (S10 … S1n) and S2 is (S20 … S2 m). In fig. 7a, 7b and 7c, S1 denotes a sensor array on the right side of the mobile terminal 100, and S10 … S1n denotes a plurality of sensors provided on the right side of the mobile terminal 100; s2 denotes a sensor array on the left side of the mobile terminal 100, and S20 … S2m denotes a plurality of sensors provided on the left side of the mobile terminal 100. In the present embodiment, the sensors used are capacitive sensors.

When the mobile terminal 100 is in the black screen state, the mobile terminal 100 detects its angle with the horizontal direction and detects whether it is in the hand-held state by a sensor. It should be noted that, in the embodiment of the present invention, the mobile terminal 100 may first detect the angle between the mobile terminal 100 and the horizontal direction, and then detect whether the mobile terminal 100 is in the hand-held state through the sensor when the angle between the mobile terminal 100 and the horizontal direction satisfies a certain condition, for example, when the angle between the mobile terminal 100 and the horizontal direction is greater than a certain set angle, the mobile terminal 100 considers that the current user may want to light the screen, and then detects whether the mobile terminal is in the hand-held state. Or, it is detected whether the mobile terminal is in a hand-held state, and when the hand-held state is detected, the mobile terminal 100 detects an angle with the horizontal direction.

Further, referring to fig. 8, the step of detecting whether the mobile terminal 100 is in a hand-held state by a sensor includes:

in step S11, a first detection value corresponding to the left sensor of the mobile terminal 100 is obtained, and a second detection value corresponding to the right sensor of the mobile terminal 100 is obtained.

In step S12, when both the first detection value and the second detection value are greater than the preset detection value, it is confirmed that the mobile terminal 100 is in a hand-held state.

In step S13, when the first detection value is less than or equal to the preset detection value and/or the second detection value is less than or equal to the preset detection value, it is determined that the mobile terminal 100 is in a non-hand-held state.

The specific process of the mobile terminal 100 detecting whether the mobile terminal is in the hand-held state through the sensor is as follows: the mobile terminal 100 acquires a first detection value corresponding to the left sensor through the left sensor, and acquires a second detection value corresponding to the right sensor through the right sensor. When the first detection value and the second detection value are acquired, the mobile terminal 100 determines whether both the first detection value and the second detection value are greater than a preset detection value to determine whether the mobile terminal is currently in a hand-held state.

When both the first detection value and the second detection value are greater than the preset detection value, the mobile terminal 100 confirms that it is currently in a hand-held state; when the first detection value is less than or equal to the preset detection value and/or the second detection value is less than or equal to the preset detection value, the mobile terminal 100 confirms that it is currently in a non-hand-held state. It should be noted that the preset detection value may be set according to specific situations, and the preset detection value differs according to the sensor used by the mobile terminal 100 and differs according to the calculation unit used by the sensor.

Further, when it is determined that the mobile terminal 100 is in the hand-held state, the mobile terminal 100 may also determine whether the left-hand-held state or the right-hand-held state is currently in accordance with a magnitude between the first detection value and the second detection value. If the capacitive sensors are disposed on the left and right sides of the mobile terminal 100, the first and second detection values may have different sizes due to different effective projection areas a on the left and right sides of the mobile terminal 100 in the left-hand holding state and the right-hand holding state. When the first detection value is greater than the second detection value, it indicates that the mobile terminal 100 is currently in a left-handed holding state; when the second detection value is greater than the first detection value, it indicates that the mobile terminal 100 is currently in a right-hand grip state.

In step S20, when the angle is within the preset angle range and the mobile terminal 100 is in the hand-held state, the mobile terminal 100 is controlled to enter the bright screen state from the black screen state.

When the angle between the mobile terminal 100 and the horizontal direction is within the preset angle range and the mobile terminal 100 is in the hand-held state, the mobile terminal 100 enters the bright screen state from the black screen state. In this embodiment, the numerical value of the preset angle range is not limited, and may be set to 20 ° to 70 °, or 28 ° to 65 °, for example, and specifically may be set according to habits of different users in holding the mobile terminal 100. Specifically, referring to fig. 9 and 10, fig. 9 is a schematic diagram of a user holding the mobile terminal 100, and fig. 10 is a schematic diagram of an angle change of the mobile terminal 100 from a horizontal direction. In fig. 10, (α, β) indicates a preset angle range, α indicates a preset angle range lower limit value, and β indicates a preset angle range upper limit value.

Further, when the angle of the mobile terminal 100 to the horizontal direction is not within the preset angle range and/or the mobile terminal 100 is not in the hand-held state, the mobile terminal 100 continues to be in the black screen state.

Further, step S20 includes:

step a, when the angle is in the preset angle range, calculating the duration time of the angle in the preset angle range.

And b, when the duration is greater than or equal to the preset time and the mobile terminal 100 is in the hand-held state, controlling the mobile terminal 100 to enter the bright screen state from the black screen state.

Further, when the mobile terminal 100 determines that its angle to the horizontal direction is within the preset angle range, the mobile terminal 100 calculates a duration time of the angle within the preset range and determines whether the duration time is greater than or equal to the preset time. When the duration is greater than or equal to the preset time and the mobile terminal 100 is in the hand-held state, the mobile terminal 100 enters the bright screen state from the black screen state; when the duration is less than the preset time, the mobile terminal 100 continues to be in the black screen state. In the present embodiment, the preset time may be set to 3 seconds, 4 seconds, 5 seconds, or the like.

By judging the duration time of the angle between the mobile terminal 100 and the horizontal direction within the preset angle range, the situation that the mobile terminal 100 enters the bright screen state from the black screen state when the user shakes the mobile terminal 100 is avoided, and the accuracy rate of the mobile terminal 100 entering the bright screen state from the black screen state according to the user needs is improved.

Further, when the mobile terminal 100 detects that the angle between the mobile terminal 100 and the horizontal direction is in the process of being held by the hand, and then detects that the angle between the mobile terminal 100 and the horizontal direction starts to change, it is determined whether the change time before the angle between the mobile terminal 100 and the horizontal direction enters the preset range angle from zero is greater than the preset time length. When the preset angle range is represented by (α, β), determining whether the change time is greater than the preset time period may be understood as determining whether a duration T of the angle between the mobile terminal 100 and the horizontal direction within the range of (0, α) is greater than the preset time period T. When T > T and the detected angle is within the preset angle range, the mobile terminal 100 starts the sensor, and detects whether the mobile terminal is currently in a hand-held state through the sensor, so as to improve the accuracy of entering a bright screen state from a black screen state of the mobile terminal 100 according to the user requirement. When T is less than or equal to T, the mobile terminal 100 does not start the sensor. The preset time period can be set according to specific needs, such as 2 seconds, 3 seconds, and the like.

In the embodiment, by respectively providing at least one sensor on the left side and the right side of the mobile terminal 100, when the mobile terminal 100 is in the black screen state, the angle between the mobile terminal 100 and the horizontal direction is detected, and whether the mobile terminal 100 is in the hand-held state is detected by the sensor; when the angle is within the preset angle range and the mobile terminal 100 is in the hand-held state, the mobile terminal 100 is controlled to enter the bright screen state from the black screen state. The mobile terminal 100 is controlled to enter the bright screen state from the black screen state under the conditions that the mobile terminal 100 is not unlocked and the screen locking function key of the mobile terminal 100 is not triggered; in addition, in the invention, the mobile terminal 100 is controlled to enter the bright screen state from the black screen state only when the angle and the hand holding state are required to be met, so that the misoperation rate of controlling the mobile terminal 100 to enter the bright screen state from the black screen state is reduced.

Further, a second embodiment of the screen status control method of the present invention is proposed based on the first embodiment. The second embodiment of the screen state control method is different from the first embodiment of the screen state control method in that the screen state control method further includes:

step c, when detecting that the angle between the mobile terminal 100 in the bright screen state and the horizontal direction is not within the preset angle range, controlling the mobile terminal 100 to enter a black screen state from the bright screen state;

and/or step d, when the mobile terminal 100 is detected to be in the non-hand-held state, controlling the mobile terminal 100 to enter the black screen state from the bright screen state.

When the mobile terminal 100 in the bright screen state detects that the angle between the mobile terminal 100 and the horizontal direction is not within the preset angle range, the mobile terminal 100 enters a black screen state from the bright screen state; when the mobile terminal 100 in the bright screen state detects that the angle between the mobile terminal 100 and the horizontal direction is within the preset angle range, but the mobile terminal is currently in the non-hand-held state, entering a black screen state from the bright screen state; when the mobile terminal 100 in the bright screen state detects that the angle between the mobile terminal 100 and the horizontal direction is not within the preset angle range and is currently in the non-hand-held state, the mobile terminal enters the black screen state from the bright screen state.

By controlling the mobile terminal 100 to enter the black screen state from the bright screen state when the angle between the mobile terminal 100 in the bright screen state and the horizontal direction is not within the preset angle range and/or the mobile terminal 100 is in the non-handheld state, the situation that the mobile terminal 100 is still in the bright screen state all the time when the user does not need to light the screen of the mobile terminal 100 is avoided, the electric quantity of the mobile terminal 100 is saved, and the intelligence of the mobile terminal 100 is improved.

Further, the screen state control method further includes:

and e, when detecting that the mobile terminal 100 is in a non-hand-held state, judging whether the running application program exists in the foreground of the mobile terminal 100.

And f, if the foreground of the mobile terminal 100 does not have the running application program, controlling the mobile terminal 100 to enter a black screen state from a bright screen state.

Further, the screen state control method further includes:

and g, if the application program running in the foreground of the mobile terminal 100 exists, controlling the mobile terminal 100 to be in a bright screen state.

Further, when the mobile terminal 100 in the bright screen state detects that it is currently in the non-handheld state through the sensor, the mobile terminal 100 determines whether there is an application running in the foreground. When the application program running in the foreground of the mobile terminal 100 exists, the mobile terminal 100 maintains a bright screen state; when the running application does not exist in the foreground of the mobile terminal 100, the mobile terminal 100 enters a black screen state from a bright screen state.

For example, when the mobile terminal 100 in the bright screen state detects that it is currently in the non-handheld state through the sensor and the foreground thereof is playing the video through the player, the mobile terminal 100 maintains the bright screen state.

When the mobile terminal 100 in the bright screen state is in the non-hand-held state, whether an application program running in the foreground of the mobile terminal 100 exists is further detected, and if the application program running in the foreground exists, the mobile terminal 100 is controlled to be in the bright screen state continuously, so that the situation that the mobile terminal 100 automatically enters the black screen state from the bright screen state when a user places the mobile terminal 100 on a desk, or watches videos in a specific place, or browses webpages and the like is avoided.

Further, a third embodiment of the screen status control method of the present invention is proposed based on the first embodiment.

The third embodiment of the screen state control method is different from the first embodiment of the screen state control method in that, referring to fig. 11, the screen state control method further includes:

in step S30, when it is detected that the angle of the mobile terminal 100 in the bright screen state to the horizontal direction is increasing, the mobile terminal 100 is unlocked.

The mobile terminal 100 in the bright screen state detects its angle with the horizontal direction in real time. When the mobile terminal 100 in the bright screen state detects that the angle between the mobile terminal 100 and the horizontal direction is increasing, the mobile terminal 100 enters an unlocking state from the bright screen state, and an unlocking operation is performed to unlock the mobile terminal 100.

In the embodiment, when it is detected that the angle between the mobile terminal 100 in the bright screen state and the horizontal direction is increased, it is considered that the user wants to view the content of the mobile terminal 100, or manipulate the mobile terminal 100, and the like, at this time, the mobile terminal 100 is unlocked, and at this time, the user does not need to unlock the mobile terminal 100 by fingerprint unlocking or manually inputting an unlocking password, so that the unlocking process of unlocking the mobile terminal 100 is simplified.

Further, a fourth embodiment of the screen status control method of the present invention is proposed based on the first, second, or third embodiment. The fourth embodiment of the screen status control method is different from the first, second and third embodiments of the screen status control method in that a rear sensor is provided at the rear of the mobile terminal 100, and referring to fig. 12, step S20 includes:

step S21, when the angle is within the preset angle range and the mobile terminal 100 is in a hand-held state, obtaining a third detection value corresponding to the back sensor;

in step S22, when the third detection value is not zero, the mobile terminal 100 is controlled to enter the bright screen state from the black screen state.

The rear surface of the mobile terminal 100 is provided with at least one rear surface sensor. When a back sensor is provided on the back of the mobile terminal 100, the back sensor may be provided in the middle of the back of the mobile terminal 100 in order to detect a user holding operation. It is to be understood that the position of the rear sensor at the rear of the mobile terminal 100 is not limited to the present embodiment. In the present invention, it is preferable that two sensors are provided on the rear surface of the mobile terminal 100. Specifically, referring to fig. 6 or 7a, one sensor S3 is disposed above the rear surface of the mobile terminal 100, and the other sensor S0 is disposed below the rear surface of the mobile terminal 100.

When the mobile terminal 100 in the black screen state detects that the angle between the mobile terminal 100 and the horizontal direction is within the preset angle range and the mobile terminal is currently in the hand-held state, the mobile terminal 100 acquires a third detection value corresponding to the back sensor and determines whether the third detection value is zero. When the third detection value is not zero, the mobile terminal 100 enters a bright screen state from a black screen state; when the third detection value is zero, the mobile terminal 100 maintains the black screen state.

Further, it may be set that the mobile terminal 100 enters the bright screen state from the black screen state only when the third detection value is greater than a certain fixed value; when the third detection value is less than or equal to the fixed value, the mobile terminal 100 continues to be in the black screen state.

In this embodiment, by setting the back sensor on the back of the mobile terminal 100, by detecting the third detection value corresponding to the back sensor, when the third detection value meets the condition, the mobile terminal 100 enters the bright screen state from the black screen state, the angle between the mobile terminal 100 and the horizontal direction is within the preset angle range, and under the condition that the detection values corresponding to the sensors on the left and right sides of the mobile terminal 100 meet the condition, whether to control the mobile terminal 100 to enter the bright screen state from the black screen state is further determined according to the third detection value corresponding to the back sensor of the mobile terminal 100, so that the accuracy of the mobile terminal 100 entering the bright screen state from the black screen state according to the user needs is improved.
