Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.
The embodiment of the application firstly provides a screen control method, and the screen control method is applied to electronic equipment. The execution main body of the screen control method may be the screen control device provided in the embodiment of the present application, or an electronic device integrated with the screen control device, where the screen control device may be implemented in a hardware or software manner, and the electronic device may be a device with processing capability and configured with a processor, such as a smart phone, a tablet computer, a palmtop computer, a notebook computer, or a desktop computer.
Referring to fig. 1, fig. 1 is a flowchart illustrating a screen control method according to an embodiment of the present disclosure. The screen control method is applied to the electronic device provided by the embodiment of the application, the first capacitive proximity sensor is arranged on the surface where the screen is located or on the opposite surface of the surface where the screen is located of the electronic device, as shown in fig. 1, the flow of the screen control method provided by the embodiment of the application may be as follows:
in 101, an induced capacitance value of a first capacitive proximity sensor is acquired.
Referring to fig. 2, in the embodiment of the present application, a surface (also referred to as a front surface) of a screen of an electronic device includes a display area and a non-display area. The display area is used for displaying information such as images and texts, receiving touch operation of a user and interacting with the user. The non-display area does not display information and can be used for setting some functional components, such as a camera, a microphone, a receiver and the like. As shown in the first drawing, a capacitive proximity sensor, which is denoted as a first capacitive proximity sensor, is disposed in a non-display area of a surface of the electronic device where the screen is located. In addition, the first capacitive sensor may be disposed on the opposite side (i.e., the back side) of the screen.
It should be noted that a capacitive proximity sensor includes a measuring head, which is equivalent to one plate of a capacitor, and a housing, which is grounded and equivalent to the other plate of the capacitor. Thus, when an object approaches the capacitive proximity sensor, whether the object is a conductor or not, the value of the capacitance of the capacitive proximity sensor is always caused to change due to its proximity.
In the embodiment of the application, the motion track of the electronic device, which is arranged on the first capacitive proximity sensor, is identified by using the change of the induced capacitance value of the capacitive proximity sensor caused when an external object approaches the capacitive proximity sensor.
The electronic device first obtains the induction capacitance value of the first capacitive proximity sensor, for example, the electronic device is provided with a capacitance value cache region in advance, and the electronic device can read the induction capacitance value of the first capacitive proximity sensor in real time and cache the read induction capacitance value of the first capacitive proximity sensor into the capacitance value cache region.
At 102, whether the electronic device is picked up is identified according to the inductive capacitance value of the first capacitive proximity sensor.
For example, a conversion rule of an induction capacitance value and a motion trajectory is preset in the electronic device, and after the electronic device obtains the induction capacitance value of the first capacitive proximity sensor, the electronic device further converts the induction capacitance value of the first capacitive proximity sensor into the motion trajectory of the electronic device according to the preset conversion rule of the induction capacitance value and the motion trajectory. Then, the electronic device compares the motion trajectory obtained by the conversion with a preset motion trajectory of the electronic device to be picked up, and if the similarity between the two motion trajectories reaches a preset similarity (which can be set as an empirical value according to actual needs by a person skilled in the art, for example, can be set as 80%), the electronic device determines that the electronic device is picked up, otherwise, the electronic device determines that the electronic device is not picked up.
In 103, if the electronic device is picked up and the screen is in the off-screen state, the screen is switched to the bright-screen state.
In the embodiment of the application, when the electronic device judges that the electronic device is taken up, it is assumed that a user currently has a requirement for using the electronic device, at the moment, whether the screen is in a screen off state is further identified, and if the screen is identified to be in the screen off state, the screen is switched to a screen on state for unlocking by the user. Correspondingly, the user can unlock the electronic device according to a preset unlocking mode, such as fingerprint unlocking, iris unlocking, password unlocking and the like.
As can be seen from the above, in the embodiment of the application, the electronic device may obtain the induction capacitance value of the first capacitive proximity sensor, and identify whether the electronic device is picked up by using the induction capacitance value of the first capacitive proximity sensor, when the electronic device is identified to be picked up, it indicates that a user currently has a need to use the electronic device, and if the screen is in the screen-off state at this time, the screen is switched to the screen-on state, so that the user can unlock the electronic device. Compared with the prior art, the electronic equipment has the advantages that when the user takes up the electronic equipment, the screen can be automatically lightened, the manual lightening of the screen of the user is not needed, and the usability of the electronic equipment can be improved.
In one embodiment, "identifying whether the electronic device is picked up according to the sensing capacitance value of the first capacitive proximity sensor" includes:
and if the inductive capacitance value of the first capacitive proximity sensor is continuously increased in a first time length and is continuously unchanged in a second time length adjacent to the first time length, judging that the electronic equipment is picked up.
In the embodiment of the application, when the electronic device identifies whether the electronic device is picked up according to the induction capacitance value of the first capacitive proximity sensor, the obtained induction capacitance value of the first capacitive proximity sensor is firstly analyzed, and the change trend information of the induction capacitance value of the first capacitive proximity sensor in a preset first time period is obtained through analysis. The first time length can be set according to the time length of a sample collected in advance from the time when the user holds the electronic equipment to the time when the user holds the electronic equipment, and the time length of a habit of the user from the time when the user holds the electronic equipment to the time when the user holds the electronic equipment can be reflected.
For example, referring to fig. 3, a sample time length for a user to perform "stretch and hold an electronic device to an electronic device" for multiple times may be collected, an average sample time length of the sample time lengths is calculated, and a preset correction time length is added to the average sample time length to obtain a time length sum value as a first time length, where the preset correction time length may be set by a person skilled in the art according to actual needs, and the preset correction time length is not specifically limited in this embodiment of the present application, for example, set to 1 second.
Similarly, in the embodiment of the application, according to the setting mode of the first time length, the second time length is correspondingly set according to the pre-collected sample time length from the time when the user takes the electronic equipment to the time when the user moves to the use position, and the habit time length from the time when the user takes the electronic equipment to the time when the user moves to the use position can be reflected.
In the embodiment of the application, after the electronic device obtains the change trend information of the induction capacitance value of the first capacitive proximity sensor within the preset first time period by analysis, whether the induction capacitance value of the first capacitive proximity sensor continuously increases within the first time period is identified according to the change trend information, and if yes, it is determined that an action that a user stretches to reach the electronic device (that is, the induction capacitance value of the first capacitive proximity sensor continuously increases in the process that the palm of the user approaches the electronic device).
Then, the electronic device further analyzes the change trend information of the induction capacitance value of the first capacitive proximity sensor in a second time period adjacent to the first time period according to the acquired induction capacitance value of the first capacitive proximity sensor, and identifies whether the induction capacitance value of the first capacitive proximity sensor continuously increases in the second time period according to the change trend information, if so, it is determined that the user moves from taking the electronic device to the use position (that is, after the user takes the electronic device with the palm, the induction capacitance value of the first capacitive proximity sensor is kept at the maximum value).
Referring to fig. 4, when it is determined that there is an operation of the user reaching to the handling recognition and a continuous operation of the user moving from the handling to the use position, the electronic device determines that the electronic device is picked up by the user.
In one embodiment, the electronic device further includes a second capacitive proximity sensor disposed in the first non-display area, and the electronic device is determined to be picked up if the sensing capacitance of the first capacitive proximity sensor is continuously increased within a first time period and is continuously unchanged within a second time period adjacent to the first time period, including:
(1) if the inductive capacitance value of the first capacitive proximity sensor is continuously increased within a first time length and is continuously unchanged within a second time length adjacent to the first time length, judging whether the inductive capacitance value of the second capacitive proximity sensor is continuously increased within the second time length;
(2) and if the inductive capacitance value of the second capacitive proximity sensor continuously increases within the second time period, determining that the electronic equipment is picked up.
Referring to fig. 5, in the embodiment of the present application, a non-display area of a surface where a screen of an electronic device is located is divided into two areas, which are a first non-display area located above a display area and a second non-display area located below the display area. The first non-display area is provided with a telephone receiver, a camera and the like, and the second non-display area is provided with a microphone, a Home key and the like. In the embodiment of the present application, the first capacitive proximity sensor is disposed in the second non-display region, and in addition, the first capacitive proximity sensor may be disposed in a target region (not shown in fig. 5) opposite to the second non-display region in the opposite surface of the screen.
In the embodiment of the application, in order to more accurately judge whether the electronic device is picked up, the judgment is assisted by the second capacitive proximity sensor arranged in the second non-display area.
When the electronic equipment analyzes that the induction capacitance value of the first capacitive proximity sensor continuously increases in a first time length and continuously does not change in a second time length adjacent to the first time length, the electronic equipment does not immediately judge that the electronic equipment is taken up, but further acquires the induction capacitance value of the second capacitive proximity sensor, analyzes the acquired induction capacitance value of the second capacitive proximity sensor, and analyzes to acquire the change trend information of the induction capacitance value of the second capacitive proximity sensor in the second time length.
For example, referring to fig. 4, during the process of moving the user from the electronic device to the use position, the sensing capacitance value of the second capacitive proximity sensor continuously increases due to the approach of the user's face. Based on this, if the sensing capacitance value of the first capacitive proximity sensor continuously increases in a first time period and continuously does not change in a second time period adjacent to the first time period, and the sensing capacitance value of the second capacitive proximity sensor continuously increases in the second time period, the electronic device determines that the electronic device is picked up.
In one embodiment, before "determining that the electronic device is taken up", the method further includes:
(1) if the induction capacitance value of the second capacitive proximity sensor continuously increases within a second time period, acquiring the maximum induction capacitance value of the first capacitive proximity sensor and acquiring the maximum induction capacitance value of the second capacitive proximity sensor;
(2) and if the maximum induction capacitance value of the first capacitive proximity sensor reaches a first preset threshold value and the maximum induction capacitance value of the second capacitive proximity sensor reaches a second preset threshold value, judging that the electronic equipment is picked up.
It should be noted that when the types of objects approaching the capacitive proximity sensor are different, even if the approaching distances of different objects are the same, the values of the induced capacitances generated by the capacitive proximity sensor are different, and therefore, in the embodiment of the present application, the living body detection is further performed by using the first capacitive proximity sensor and the second capacitive proximity sensor provided in the electronic device, so as to improve the accuracy of determining whether the electronic device is picked up.
When the electronic equipment analyzes that the induction capacitance value of the first capacitive proximity sensor continuously increases in a first time length and continuously does not change in a second time length adjacent to the first time length, and the induction capacitance value of the second capacitive proximity sensor continuously increases in the second time length, the electronic equipment does not immediately judge that the electronic equipment is taken up, but further acquires the maximum induction capacitance value of the first capacitive proximity sensor and acquires the maximum induction capacitance value of the second capacitive proximity sensor.
Then, the electronic device compares the acquired maximum sensing capacitance value of the first capacitive proximity sensor with a first preset threshold value, and compares the acquired maximum sensing capacitance value of the second capacitive proximity sensor with a second preset threshold value, wherein the first preset threshold value can be set according to the sensing capacitance value of the first capacitive proximity sensor when a user who is acquired in advance holds the electronic device, and the second preset threshold value can be set according to the sensing capacitance value of the second capacitive proximity sensor when the user who is acquired in advance holds the electronic device at a use position.
For example, the electronic device may collect a sample induction capacitance value of the first capacitive proximity sensor when the user holds the electronic device for a plurality of times, calculate an average sample induction capacitance value of the plurality of sample induction capacitance values, and set the sample induction capacitance value as a first preset threshold value.
For another example, the electronic device may collect sample sensing capacitance values of the second capacitive proximity sensor when the user holds the electronic device for multiple times at the use position, calculate an average sample sensing capacitance value of the sample sensing capacitance values, and set the sample sensing capacitance value as the second preset threshold.
It will be appreciated by those skilled in the art that when the first and second capacitive proximity sensors are the same type of capacitive proximity sensor, the first preset threshold will be set greater than the second preset threshold.
As described above, when the maximum sensing capacitance value of the first capacitive proximity sensor reaches the first preset threshold and the maximum sensing capacitance value of the second capacitive proximity sensor reaches the second preset threshold, it indicates that the user currently holds the electronic device and the electronic device is in the use position, and the electronic device determines that the electronic device is taken up.
In one embodiment, "if the electronic device is picked up and the screen is in the off-screen state, the screen is switched to the on-screen state", including:
(1) if the electronic equipment is picked up and the screen is in a screen-off state, acquiring the sight line position of the user;
(2) and if the sight line position of the user is positioned in the display area of the screen, switching the screen to a bright screen state.
In the embodiment of the application, in order to avoid the situation that the electronic equipment is meaningless bright screen due to the fact that a user carelessly picks up the electronic equipment, when the screen is switched to the bright screen state, if the electronic equipment is picked up and the screen is in the screen off state, the electronic equipment firstly acquires the sight position of the user to judge whether the user has the requirement for using the electronic equipment according to the sight position of the user, when the sight position of the user is located in the display area of the screen, the electronic equipment judges that the user has the requirement for using the electronic equipment, and at the moment, the screen is switched to the bright screen state.
How to acquire the gaze position of the user can be realized by selecting an appropriate eye tracking algorithm according to actual needs by those skilled in the art, which is not particularly limited in the embodiment of the present application.
In an embodiment, "if the electronic device is picked up and the screen is in the off-screen state, then switching the screen to the on-screen state" further includes:
if the current state is a call state and the induction capacitance value of the second capacitive proximity sensor is within the preset capacitance value interval, the screen is switched to a screen extinguishing state.
It is easy to understand that the conversation is the high frequency scene of electronic equipment, and the user can be pressed close to the face with electronic equipment usually when the conversation, in order to avoid the conversation to be hung up by the mistake, in this application embodiment, electronic equipment detects the conversation state, and when being in the conversation state, whether the inductive capacitance value of further discernment second capacitanc proximity sensor is located and predetermines the capacitance value interval, then judges that electronic equipment is close to the user face this moment, switches the screen to the state of turning off the screen promptly.
The preset capacitance interval can be set according to the induction capacitance of the second capacitive proximity sensor during the user call period collected in advance. For example, the minimum sensing capacitance value and the maximum sensing capacitance value of the second capacitive proximity sensor during a call of the user may be obtained, and a capacitance value interval formed by the minimum sensing capacitance value and the maximum sensing capacitance value may be used as a preset capacitance value interval for determining whether the electronic device is close to the face of the user.
In an embodiment, "if the electronic device is picked up and the screen is in the off-screen state, then switching the screen to the on-screen state" further includes:
(1) identifying whether the electronic equipment is put down according to the induction capacitance value of the first capacitive proximity sensor;
(2) if the electronic equipment is put down and the screen is in a bright screen state, the screen is switched to a screen-off state.
In order to further improve the usability of the electronic equipment, the screen is automatically turned off when the electronic equipment is recognized to be put down in the embodiment of the application.
The electronic equipment can convert the inductive capacitance value of the first capacitive proximity sensor into the motion track of the electronic equipment according to a preset conversion rule of the inductive capacitance value and the motion track. Then, the electronic device compares the motion trajectory obtained by conversion with a preset motion trajectory of the electronic device being dropped, and if the similarity between the two motion trajectories reaches a preset similarity (which can be set as an empirical value according to actual needs by a person skilled in the art, for example, can be set as 80%), the electronic device determines that the electronic device is dropped, otherwise, the electronic device determines that the electronic device is not dropped.
When the screen is judged to be put down, the fact that the user does not have the requirement for using the electronic equipment temporarily is indicated, whether the screen is in a bright screen state or not is further identified, and if the screen is identified to be in the bright screen state, the screen is switched to an off screen state.
In one embodiment, "whether the electronic device is put down is identified according to the sensing capacitance value of the first capacitive proximity sensor", further comprising:
and if the value of the induction capacitance of the first capacitive proximity sensor is continuously unchanged in a third time period and is continuously reduced in a fourth time period adjacent to the third time period, determining that the electronic equipment is put down.
Referring to the manner in which the electronic device identifies whether the electronic device is picked up according to the sensing value of the first capacitive proximity sensor, in this embodiment of the application, the electronic device may also identify whether the electronic device is put down according to the sensing capacitance value of the first capacitive proximity sensor.
In the embodiment of the application, when the electronic device identifies whether the electronic device is put down according to the sensing capacitance value of the first capacitive proximity sensor, the obtained sensing capacitance value of the first capacitive proximity sensor is firstly analyzed, and the variation trend information of the sensing capacitance value of the first capacitive proximity sensor in a preset third time period is obtained through analysis. The third time length can be set according to the time length of a sample acquired in advance when the user holds the electronic equipment and puts down the electronic equipment, and the habitual time length of the user putting down the electronic equipment from the use position can be reflected.
Similarly, in the embodiment of the application, according to the setting mode of the third time length, the fourth time length is correspondingly set according to the time length of the sample collected in advance from the electronic device being put down to the palm being taken away by the user, and the habit time length of the user taking away from the palm after the electronic device is put down can be reflected.
In the embodiment of the application, after the electronic device obtains the variation trend information of the sensing capacitance value of the first capacitive proximity sensor within the preset third time period by analysis, whether the sensing capacitance value of the first capacitive proximity sensor is continuously unchanged within the third time period is identified according to the variation trend information, and if yes, it is determined that there is an action of the user to put down the electronic device from the use position.
Then, the electronic device further analyzes the obtained sensing capacitance value of the first capacitive proximity sensor to obtain variation trend information of the sensing capacitance value of the first capacitive proximity sensor in a fourth time period adjacent to the third time period, and identifies whether the sensing capacitance value of the second capacitive proximity sensor is continuously reduced in the fourth time period according to the variation trend information, if so, it is determined that the palm holding action of the user exists.
Referring to fig. 6, the electronic apparatus determines that the user has dropped the electronic apparatus when determining that there is an operation of the user to drop the electronic apparatus from the use position and that the user has continuously taken the palm off.
In one embodiment, as shown in fig. 5, when the electronic device is provided with a first capacitive proximity sensor and a second capacitive proximity sensor, "if the value of the capacitance of the first capacitive proximity sensor is continuously constant for a third time period and is continuously decreased for a fourth time period adjacent to the third time period, it is determined that the electronic device is down" includes:
(1) if the induction capacitance value of the first capacitive proximity sensor is continuously unchanged in the third time length and is continuously reduced in the fourth time length adjacent to the third time length, judging whether the induction capacitance value of the second capacitive proximity sensor is continuously reduced in the third time length;
(2) and if the value of the induction capacitance of the first capacitive proximity sensor is continuously reduced within the third time period, determining that the electronic equipment is put down.
In the embodiment of the application, in order to judge whether the electronic device is put down more accurately, the second capacitive proximity sensor arranged in the second non-display area is used for assisting in judging.
When the electronic equipment analyzes that the induction capacitance value of the first capacitive proximity sensor is continuously unchanged in the third time period and continuously becomes smaller in the fourth time period adjacent to the third time period, the electronic equipment does not immediately judge that the electronic equipment is put down, but further acquires the induction capacitance value of the second capacitive proximity sensor, analyzes the acquired induction capacitance value of the second capacitive proximity sensor, and analyzes to acquire the change trend information of the induction capacitance value of the second capacitive proximity sensor in the third time period.
For example, referring to fig. 7, during the process of the user lowering the electronic device from the usage position, the sensing capacitance value of the second capacitive proximity sensor is continuously decreased due to the face of the user. Based on this, if the value of the sensing capacitance of the first capacitive proximity sensor is continuously unchanged for a third time period and is continuously decreased for a fourth time period adjacent to the third time period, and the value of the sensing capacitance of the second capacitive proximity sensor is continuously decreased for the third time period, the electronic device determines that the electronic device is put down.
Referring to fig. 8 and 5 together, fig. 8 is another schematic flow chart of a screen control method provided in an embodiment of the present application, where the screen of the electronic device includes a display area and a non-display area, the non-display area includes a first non-display area and a second non-display area, the first non-display area and the second non-display area are located at two ends of the display area respectively, the first non-display area is provided with a second capacitive proximity sensor, and the second non-display area is provided with a first capacitive proximity sensor, where the flow chart of the screen control method may include:
in 201, the electronic device obtains an induced capacitance value of a first capacitive proximity sensor and obtains an induced capacitance value of a second capacitive proximity sensor.
Referring to fig. 5, in the embodiment of the present application, a non-display area of a surface where a screen of an electronic device is located is divided into two areas, which are a first non-display area located above a display area and a second non-display area located below the display area. The first non-display area is provided with a telephone receiver, a camera and the like, and the second non-display area is provided with a microphone, a Home key and the like. In order to accurately judge whether the electronic device is picked up or put down, in the embodiment of the application, the sensing capacitance values of the first capacitive proximity sensor and the second capacitive proximity sensor are integrated to judge.
The electronic device may read the sensing capacitance value of the first capacitive proximity sensor in real time, and cache the read sensing capacitance value of the first capacitive proximity sensor in the capacitance buffer area, and read the sensing capacitance value of the second capacitive proximity sensor in real time, and cache the read sensing capacitance value of the second capacitive proximity sensor in the capacitance buffer area.
At 202, the electronic device identifies whether it is picked up based on the sensed capacitance value of the first capacitive proximity sensor and the sensed capacitance value of the second capacitive proximity sensor.
The electronic equipment analyzes the acquired induction capacitance value of the first capacitive proximity sensor to obtain the change trend information of the induction capacitance value of the first capacitive proximity sensor within a preset first time period.
After the electronic device obtains the change trend information of the induction capacitance value of the first capacitive proximity sensor in the preset first time period through analysis, whether the induction capacitance value of the first capacitive proximity sensor continuously increases in the first time period is identified according to the change trend information, and if yes, it is determined that there is a possibility that a user stretches his hand to take the electronic device.
Then, the electronic device further analyzes the obtained change trend information of the induction capacitance value of the first capacitive proximity sensor in a second time period adjacent to the first time period according to the obtained induction capacitance value of the first capacitive proximity sensor, and identifies whether the induction capacitance value of the first capacitive proximity sensor continuously increases in the second time period according to the change trend information, if so, it is determined that an action of moving the user from the electronic device to the use position may exist.
In addition, when the electronic equipment analyzes that the inductive capacitance value of the first capacitive proximity sensor is continuously increased in a first time length and is continuously unchanged in a second time length adjacent to the first time length, the obtained inductive capacitance value of the second capacitive proximity sensor is analyzed, and the change trend information of the inductive capacitance value of the second capacitive proximity sensor in the second time length is obtained through analysis.
For example, referring to fig. 4, during the process of moving the user from the electronic device to the use position, the sensing capacitance value of the second capacitive proximity sensor continuously increases due to the approach of the user's face. Based on this, if the sensing capacitance value of the first capacitive proximity sensor continuously increases in a first time period and continuously does not change in a second time period adjacent to the first time period, and the sensing capacitance value of the second capacitive proximity sensor continuously increases in the second time period, the electronic device determines that the electronic device is picked up.
In 203, if it is recognized that the electronic device is picked up and the screen is in the screen-off state, the electronic device switches the screen to the screen-on state.
In the embodiment of the application, when the electronic device judges that the electronic device is taken up, it is assumed that a user currently has a requirement for using the electronic device, at the moment, whether the screen is in a screen off state is further identified, and if the screen is identified to be in the screen off state, the screen is switched to a screen on state for unlocking by the user. Correspondingly, the user can unlock the electronic device according to a preset unlocking mode, such as fingerprint unlocking, iris unlocking, password unlocking and the like.
At 204, the electronic device identifies whether it is dropped based on the sensed capacitance value of the first capacitive proximity sensor and the sensed capacitance value of the second capacitive proximity sensor.
The electronic equipment analyzes the acquired induction capacitance value of the first capacitive proximity sensor to obtain the variation trend information of the induction capacitance value of the first capacitive proximity sensor within a preset third time period.
After the variation trend information of the sensing capacitance value of the first capacitive proximity sensor in the preset third time period is obtained through analysis, the electronic device identifies whether the sensing capacitance value of the first capacitive proximity sensor is continuously unchanged in the third time period according to the variation trend information, and if yes, it is determined that an action of putting down the electronic device from the use position by the user may exist.
Then, the electronic device further analyzes the obtained sensing capacitance value of the first capacitive proximity sensor to obtain variation trend information of the sensing capacitance value of the first capacitive proximity sensor in a fourth time period adjacent to the third time period, and identifies whether the sensing capacitance value of the second capacitive proximity sensor is continuously reduced in the fourth time period according to the variation trend information, if so, it is determined that the palm holding action of the user may exist.
In addition, when the electronic device analyzes that the induction capacitance value of the first capacitive proximity sensor is continuously unchanged in the third time period and continuously decreases in the fourth time period adjacent to the third time period, the electronic device further analyzes the acquired induction capacitance value of the second capacitive proximity sensor to obtain the change trend information of the induction capacitance value of the second capacitive proximity sensor in the third time period.
For example, referring to fig. 7, during the process of the user lowering the electronic device from the usage position, the sensing capacitance value of the second capacitive proximity sensor is continuously decreased due to the face of the user. Based on this, if the value of the sensing capacitance of the first capacitive proximity sensor is continuously unchanged for a third time period and is continuously decreased for a fourth time period adjacent to the third time period, and the value of the sensing capacitance of the second capacitive proximity sensor is continuously decreased for the third time period, the electronic device determines that the electronic device is put down.
In 205, if the electronic device recognizes that the electronic device is dropped and the screen is in the bright screen state, the electronic device switches the screen to the off screen state.
When the screen is judged to be put down, the fact that the user does not have the requirement for using the electronic equipment temporarily is indicated, whether the screen is in a bright screen state or not is further identified, and if the screen is identified to be in the bright screen state, the screen is switched to an off screen state.
