[0037] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0038] The display control method provided in the embodiment of the present disclosure is applied to the display scene of the electronic device display screen. The display control method involved in the embodiment of the present disclosure is mainly applied to the display control scene of the electronic device with a display screen. For example, it is applied to the scene of the display of the flat panel display screen.

[0039] The display control method in the related technology is implemented based on the smart eye sensing system when the electronic device display screen displays, which is strongly dependent on the neural network. There is a situation of mis-locking when the cover is not closed; in addition, the screen response time is long, the user experience is poor, and it cannot cover the scene where there are stationary objects within 0.7m-0.9m behind the screen, such as the scene where there is a chair.

[0040] Moreover, in most cases, the display of the electronic device screen is based on the touch sensing function to light up the screen so that the user can proceed to the next step of unlocking and using it. The operation is cumbersome and the user experience is poor.

[0041] In view of this, the present disclosure provides a display control method, which is based on the detectable range of the distance sensor of the electronic device and the condition that the screen display control is performed based on the distance to turn on or lock the screen. The screen display of the electronic device is more accurately controlled based on the distance detected for the first time between the user and the electronic device, and the user's intention to turn on or lock the screen of the electronic device is quickly and accurately identified, thereby improving the accuracy of the screen display control.

[0042] Figure 1 FIG. 1 is a flow chart of a display control method according to an exemplary embodiment. Figure 1As shown, the display control method is used in an electronic device and includes the following steps.

[0043] In step S11 , the distance between the user and the electronic device is detected based on a distance sensor of the electronic device.

[0044] In the embodiment of the present disclosure, the screen is turned on when a user approaches and is locked when the user leaves, depending on the distance between the user and the electronic device.

[0045] The distance sensor of the electronic device involved in the present disclosure detects the distance between the user and the electronic device, which can be understood as the optimal distance value between the user and the electronic device that can be detected by the electronic device with good performance.

[0046] In step S12, in response to determining that the screen control condition is met based on the detected distance, a first distance value between the user and the electronic device detected for the first time under the screen control condition is determined, wherein the screen control condition includes the user being away from the electronic device or the user being close to the electronic device.

[0047] In the embodiment of the present disclosure, a first distance value between the user and the electronic device is determined according to the detected distance that satisfies the screen control condition.

[0048] The screen control condition involved in the present disclosure can be understood as the screen control range in which the distance sensor of the electronic device detects that the user has entered the detectable range, that is, the screen control range in which the distance sensor can report the current user distance, and the state of the user in the current range satisfies the reporting state. The first distance value can be understood as the first data recorded by the distance sensor of the electronic device when it detects that the user has entered the detectable range.

[0049] In step S13, screen display control is performed based on the screen control condition and the first distance value.

[0050] In the embodiment of the present disclosure, display control is performed to light up the screen when a person comes and lock the screen when a person leaves based on the screen control condition and the first distance value detected by the distance sensor of the electronic device.

[0051] Among them, screen display control can be understood as the display control of the electronic device display screen to light up when a user approaches and lock the screen when the user leaves after the distance sensor of the electronic device detects the distance between the user and the electronic device.

[0052] In the disclosed embodiment, the distance between the user and the electronic device is detected by a distance sensor of the electronic device, and on the basis of determining whether the user currently meets the screen control conditions of the electronic device, operations of lighting the screen when the user approaches and locking the screen when the user leaves are performed according to the distance between the user and the electronic device. The response time of the electronic device is shortened and the screen can be controlled without the user performing touch operations.

[0053] Figure 2 FIG. 1 is a flow chart of a method for controlling a display screen to be bright according to an exemplary embodiment. Figure 2 As shown, the following steps are included:

[0054] In step S21, in response to the screen control condition that the user is close to the electronic device and the screen of the electronic device is in a locked state, a second distance value detected in real time by the distance sensor is determined, and a real-time distance threshold is determined based on the first distance value and / or the second distance value. The real-time distance threshold is the maximum distance value at which the electronic device can identify the user.

[0055] In the embodiment of the present disclosure, a screen lighting control operation is performed on the electronic device display according to the screen control conditions.

[0056] The second distance value can be understood as the distance value between the user and the electronic device detected in real time by the distance sensor when the user approaches the electronic device again. The distance threshold can be understood as the maximum distance value based on which the distance detector determines whether the user is currently operating the electronic device to turn on or lock the screen when the user approaches the electronic device.

[0057] In step S22, if it is continuously detected that the second distance value is smaller than the difference between the distance threshold and the preset value within the first set time period, the electronic device is controlled to change from the locked screen state to the bright screen state.

[0058] In the embodiment of the present disclosure, when the user is within the distance range detectable by the distance detector and the user's state meets the conditions required for the screen to turn on, the electronic device is controlled to change from a locked screen state to a turned-on screen state.

[0059] The first set duration can be understood as the duration of the user's stay in the screen-on range detected by the distance detector, that is, the duration of time the electronic device can determine that the user intends to turn on the screen. The preset value can be understood as a fixed value, which refers to the distance detection range value of the user's approaching the screen within a certain distance range.

[0060] In the disclosed embodiment, the distance detector detects the distance between the user and the electronic device, and then directly turns on the screen of the electronic device, which is convenient to operate and improves the user experience.

[0061] In the embodiment of the present disclosure, a real-time distance threshold is further determined based on the acquired first distance value and second distance value, wherein the method for determining the real-time distance threshold includes the following: if the first distance value is greater than a predefined maximum distance threshold, the maximum distance threshold is determined as the real-time distance threshold; or

[0062] If the first distance value is less than a predefined maximum distance threshold, determining the first distance value as a real-time distance threshold; or

[0063] If the first distance value is less than the predefined maximum distance threshold, and the second distance value is greater than the first distance value and less than the predefined maximum distance threshold, determining the second distance value as the real-time distance threshold;

[0064] If the first distance value is less than a predefined maximum distance threshold, and the second distance value is greater than the first distance value and greater than the predefined maximum distance threshold, the maximum distance threshold is determined as the real-time distance threshold.

[0065] Among them, the predefined maximum distance threshold can be understood as the maximum fixed distance value set by the electronic device when the distance sensor has not yet detected the distance between the user and the electronic device, that is, the fixed distance value set manually to enable the screen-on when someone comes and the screen-lock when someone leaves operations.

[0066] In the disclosed embodiment, a real-time distance threshold is determined based on the first distance value and / or the second distance value to ensure that the distance threshold is updated in real time when the user performs the "come and light up the screen" operation, so that subsequent users can continue to perform the "come and light up the screen" operation.

[0067] In an embodiment of the present disclosure, after the user lights up the screen when a person approaches based on the distance detected by the distance sensor and further completes an operation on the electronic device, when the user intends to lock the screen, a screen lock method is provided. For example, the distance sensor is used to detect the distance between the user and the electronic device again, and the screen lock function is implemented according to the detected distance between the user and the electronic device.

[0068] Figure 3 FIG. 1 is a flow chart of a method for displaying and locking a screen according to an exemplary embodiment. Figure 3 As shown, the following steps are included:

[0069] In step S31, in response to the screen control condition that the user is away from the electronic device and the screen of the electronic device is in a bright screen state, a second distance value detected in real time by the distance sensor is determined.

[0070] In the embodiment of the present disclosure, when the electronic display screen is in a bright screen state, if the user is away from the electronic device, the distance between the user and the electronic device in the current state is determined.

[0071] Among them, the screen control condition that the user is away from the electronic device can be understood as that the distance sensor detects that the user has the intention to lock the screen, that is, the user is away from the electronic device.

[0072] In step S32, if the second distance value is continuously detected to be greater than the predefined maximum distance threshold within the second set time period and no operation on the electronic device is detected, the electronic device is controlled to switch from the screen-on state to the screen-locked state.

[0073] In the disclosed embodiment, when the user is within the distance range detectable by the distance detector and the user's state meets the conditions required for screen lock, the electronic device is controlled to change from the screen-on state to the screen-lock state.

[0074] The second set duration can be understood as the duration of the user's stay in the lock screen range detected by the distance detector, that is, the duration during which the electronic device can determine that the user intends to lock the screen. When the distance detector detects that the user's distance is greater than the maximum fixed distance value set by the electronic device when the distance sensor has not yet detected the distance between the user and the electronic device within the duration, and the user has not operated the electronic device within this duration, the electronic device is controlled to change from the screen-on state to the screen-locked state.

[0075] In the embodiment of the present disclosure, the electronic device obtains the distance between the user and the electronic device detected by the distance sensor and the user has not operated the electronic device within a set time period, and locks the screen of the electronic device, thereby avoiding the situation where the screen is accidentally locked due to the user temporarily leaving.

[0076] In the embodiment of the present disclosure, after controlling the electronic device to switch from the screen-on state to the screen-locked state, it also includes: in response to detecting a screen-on operation on the electronic device and detecting that the second distance value is less than the difference between the distance threshold and the preset value, controlling the electronic device to change from the screen-locked state to the screen-on state.

[0077] Among them, detecting that the second distance is less than the difference between the distance threshold and the preset value can be understood as the user automatically turning off the power button or the user not operating the electronic device for a certain period of time, or the electronic device mistakenly identifying it as an object. In this case, to control the electronic device to change from the locked screen state to the bright screen state, the user needs to approach the electronic device at a distance smaller than the second distance detected at this time, and after the electronic device changes from the locked screen state to the bright screen state, if the user leaves, the distance value stored in the electronic device will be updated again.

[0078] In the disclosed embodiment, based on the detected second distance value being less than the difference between the distance threshold and the preset value, the electronic device is controlled to change from a locked screen state to a bright screen state, thereby avoiding the situation where the screen is mistakenly lit when the user is still at the current location after the screen is locked.

[0079] In the embodiment of the present disclosure, before the distance sensor of the electronic device detects the distance between the user and the electronic device, it also includes: determining that the posture of the electronic device meets a preset posture, and the preset posture is used to represent that the electronic device is in a state of being used by the user.

[0080] The posture of the electronic device can be understood as the static state or motion state reported by the absolute motion detection sensor on the electronic device, and the four-element component value reported by the game rotation vector sensor of the electronic device. The preset posture can be understood as the angle of the electronic device with the desktop that can be detected by the user, which is determined from the four-element component value reported by the game rotation vector sensor of the electronic device.

[0081] In the disclosed embodiment, when the posture of the electronic device meets the preset posture, the distance between the user and the electronic device is detected to avoid the screen being on for a long time and reduce power consumption.

[0082] Figure 4 FIG. 1 is a flowchart of an algorithm for approaching a bright screen according to an exemplary embodiment. Figure 4 As shown, the following steps are included:

[0083] In step S41, the monitor lights up the screen.

[0084] In an exemplary embodiment of the present disclosure, a user turns on the "light up screen when approaching" switch in the settings, and in the locked screen state, listens for someone to light up the screen.

[0085] In step S42, the second distance value is acquired in real time.

[0086] In an exemplary embodiment of the present disclosure, after the algorithm stores the first recorded data, the distance that the user subsequently reaches is recorded as the second distance value of the user.

[0087] In step S43, the first distance value is greater than a predefined maximum distance threshold.

[0088] In an exemplary embodiment of the present disclosure, the algorithm records the first data as the largest data, records the first data as the first distance value, and compares the first distance value with a predefined maximum distance threshold to determine whether the first distance value needs to be updated.

[0089] In step S44, the first distance value is updated, and the maximum first distance value is a predefined maximum distance threshold.

[0090] In an exemplary embodiment of the present disclosure, the first distance value is the first data recorded by the algorithm as the maximum distance value. If the data is greater than a predefined maximum distance threshold, it is recorded as the predefined maximum distance threshold.

[0091] In step S45, the first distance value is greater than the second distance value.

[0092] In an exemplary embodiment of the present disclosure, the relationship between the first distance value and the second distance value is compared, and it is determined whether the first distance value is greater than the second distance value.

[0093] In step S46, the second distance value is smaller than the difference between the first distance value and the preset value, and the duration is longer than the first set time period.

[0094] In an exemplary embodiment of the present disclosure, the relationship between the current second distance value and the difference between the first distance value and the preset value is determined. The duration being longer than the first set duration can be understood as the time required for the electronic device to confirm whether the user has the intention to turn on the screen in the current state.

[0095] In step S47, the human arrival event is reported.

[0096] In an exemplary embodiment of the present disclosure, when the state of the user meets the state condition for the electronic device to detect the presence of a person, the presence of a person is reported, so that the screen lights up.

[0097] In an exemplary embodiment of the present disclosure, a user turns on the "light up screen when approaching" switch in the settings, and in the locked screen state, enters the detection range of the distance sensor, and the screen lights up. Specifically, after the user enters the detection range of the distance sensor, if it is detected that the user is in a distance range of the difference between a first distance value and a preset value for a first set time period, the user's need to use the screen is responded to.

[0098] In an exemplary embodiment of the present disclosure, since the distance sensor needs to accurately detect the distance between the electronic device and the user and reduce the loss caused by the electronic device keeping the screen on for a long time, a detection condition that can effectively detect the distance between the user and the electronic device is set for the electronic device. For example, the condition is set to a fixed posture of the electronic device. The fixed posture can be a predetermined posture of the electronic device. When the electronic device is in the predetermined posture, the distance value detected by the distance sensor can be obtained.

[0099] In an exemplary embodiment of the present disclosure, it is determined whether the distance sensor is in a state where the distance between the user and the electronic device can be detected, and the screen lock function is implemented according to the state of the distance sensor.

[0100] Figure 5 FIG. 1 is a flowchart of an algorithm for entering and leaving the lock screen according to an exemplary embodiment. Figure 5 As shown, the following steps are included:

[0101] In step S51, the function of locking the screen when a person leaves is enabled.

[0102] In an exemplary embodiment of the present disclosure, starting the algorithm means that the user turns on a switch that allows the user to approach the bright screen and leave the locked screen.

[0103] In step S52, the posture of the electronic device is acquired.

[0104] In an exemplary embodiment of the present disclosure, the angle between the electronic device and the desktop is obtained based on the stationary or moving state reported by the absolute motion detection sensor of the electronic device and the four-element component values ​​reported by the game rotation vector sensor of the electronic device.

[0105] In step S53, the electronic device is in a stationary state.

[0106] In an exemplary embodiment of the present disclosure, the static posture can be understood as a condition in which the electronic device is stably placed when the electronic device is placed at the above angle state within the range where the electronic device can detect the user.

[0107] In step S54, the electronic device maintains a static posture for a predefined time.

[0108] In an exemplary embodiment of the present disclosure, it is determined that the electronic device remains in a static state for a predefined time, such as 2 seconds. It can be understood that when the electronic device is accidentally moved by the user or other circumstances may cause the electronic device to shake slightly, in order to prevent the electronic device from being unable to identify the distance between the user and the electronic device, it is determined that the electronic device remains static for a certain period of time under the above circumstances, and the electronic device is considered to be in a static state.

[0109] In step S55, the distance value detected by the distance sensor is acquired.

[0110] In an exemplary embodiment of the present disclosure, when the electronic device is in the above angle state, it is considered that the distance between the user and the electronic device can be detected by the distance sensor.

[0111] In step S56, the screen is locked when the person leaves.

[0112] In an exemplary embodiment of the present disclosure, the screen lock operation is performed according to the current algorithm logic.

[0113] In step S57, the tilt angle between the electronic device and the desktop is greater than a preset angle.

[0114] In an exemplary embodiment of the present disclosure, the preset angle can be understood as the angle at which the electronic device is located to be able to detect the angle condition between the user and the electronic device, for example, the angle when the electronic device is in a horizontal position with a positive support angle of 90-135 degrees with the desktop.

[0115] In step S58, the duration is greater than or equal to a predefined time.

[0116] In an exemplary embodiment of the present disclosure, the electronic device is at a current preset angle and determines whether the duration is greater than or equal to a predefined time, for example, 2S.

[0117] In an exemplary embodiment of the present disclosure, when determining whether the duration of use of the electronic device satisfies the condition, it is avoided that the user temporarily places the electronic device and causes the electronic device to be damaged due to the sensing of the distance sensor.

[0118] In step S59, no reporting is performed.

[0119] In an exemplary embodiment of the present disclosure, when the electronic device is in a non-stationary state or has an inclination angle greater than a preset angle with respect to the horizontal desktop and continues for a predefined time, the current distance will not be reported.

[0120] In step S60, the screen lock function is terminated.

[0121] In an exemplary embodiment of the present disclosure, when the electronic device completes each logic operation in the current algorithm flow, the algorithm ends.

[0122] In an exemplary embodiment of the present disclosure, the posture of the electronic device is directly acquired, and after the distance between the user and the electronic device is acquired, it is determined again whether the current electronic device is in a stationary state, and an operation of detecting the distance between the user and the electronic device is performed.

[0123] Figure 6 FIG. 1 is a flowchart of an algorithm for entering a near-bright screen according to an exemplary embodiment. Figure 6 As shown, the following steps are included:

[0124] In step S61, the screen lighting function is enabled.

[0125] In an exemplary embodiment of the present disclosure, starting the algorithm means that the user turns on a switch that sets the screen to light up when approaching and to turn off when leaving.

[0126] The specific implementation of step S62 has been specifically described in step S52 and will not be repeated here.

[0127] In step S63, the distance value detected by the distance sensor is acquired.

[0128] In an exemplary embodiment of the present disclosure, when the electronic device is in the above angle state, it is considered that the distance between the user and the electronic device can be detected by the distance sensor.

[0129] In step S64, the electronic device is in a non-stationary posture.

[0130] In an exemplary embodiment of the present disclosure, a non-stationary posture may be understood as a situation where the electronic device is placed unstably, for example, the electronic device is shaking, such as being continuously held in the hand of a user.

[0131] In step S65 , the duration is greater than or equal to a predefined time.

[0132] In an exemplary embodiment of the present disclosure, it is further determined whether the electronic device is placed unstably within a predefined time, such as 2S, for example, the electronic device is shaking, such as being held in the hand of the user for a long time, rather than the time based on the situation where the user accidentally touches it within a short period of time.

[0133] In step S66, the electronic device is in a stationary state.

[0134] In an exemplary embodiment of the present disclosure, the stationary state may be understood as a stationary state of the electronic device within a range where the electronic device can detect a user.

[0135] In step S67, the duration is equal to the predefined time.

[0136] In an exemplary embodiment of the present disclosure, it is determined that the electronic device remains stationary for a predefined time, such as 2 seconds. This can be understood as when the electronic device is accidentally moved by the user or other situations may cause the electronic device to shake slightly. In order to prevent the electronic device from being unable to identify the distance between the user and the electronic device, it is determined that the electronic device remains stationary for 2 seconds under the above situation, and the electronic device is considered to be in a stationary state.

[0137] The specific implementation of step S68 has been described in detail in step S59 and will not be repeated here.

[0138] In step S69, the screen lighting function is terminated.

[0139] In an exemplary embodiment of the present disclosure, when the electronic device completes each logic operation in the current algorithm flow, the algorithm ends.

[0140] In an exemplary embodiment of the present disclosure, when entering the proximity to bright screen algorithm, it is no longer necessary to judge the angle state of the electronic device, and the proximity to bright screen algorithm is reported in real time.

[0141] In one implementation, the display of the electronic device is controlled according to the functions of lighting the screen when approaching and locking the screen when leaving, which solves the problem of manually operating the screen and the power button in the use scenario of people coming and going, and improves the interaction between the user and the electronic device. The screen lock function automatically locks the screen after recognizing that the user has left, which improves the privacy of the user, avoids the screen being on for a long time, and reduces power consumption.

[0142] The display control method provided by the embodiment of the present disclosure identifies the distance between the user and the electronic device within the detectable range of the distance sensor of the electronic device. The display of the electronic device is operated more conveniently according to the distance between the user and the electronic device, and the user's intention to light up or lock the screen of the electronic device is quickly and accurately identified, and the electronic screen display is controlled according to the user's intention to the electronic device, thereby expanding the scope of use scenarios. When the distance sensor detects a scene with a stationary object within the recognition range, such as a chair, the screen lock caused by misjudging the user's intention to lock the screen is avoided, and the user is ensured to unlock and further use the electronic device without touching it, freeing the user's hands. Moreover, in the embodiment of the present disclosure, when the state of the electronic device meets the conditions for user use, such as when the posture of the electronic device meets the preset posture, the distance sensor is enabled for distance monitoring, which can reduce the power consumption of screen display control based on distance.

[0143] Based on the same concept, an embodiment of the present disclosure also provides a display control device.

[0144] It is understandable that the display control device provided by the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function in order to realize the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.

[0154] In one embodiment, the control unit 103 controls the electronic device to switch from the screen-on state to the screen-locked state in the following manner: in response to the screen control condition that the user actively turns off the electronic device or locks the screen due to a timeout, or the screen is mistakenly identified as being locked by an object, the electronic device is controlled to switch from the screen-on state to the screen-locked state.

[0155] In one implementation, the control unit 103 detects the distance between the user and the electronic device based on the distance sensor of the electronic device in the following manner: determining that the posture of the electronic device meets a preset posture, where the preset posture is used to represent that the electronic device is in a state of being used by the user.
