Before explaining the embodiments of the present disclosure in detail, an application scenario of the embodiments of the present disclosure will be described.

Currently, fingerprint recognition technology has been widely used in mobile terminals. The fingerprint identification technology can be mainly divided into three types, namely key-type fingerprint identification, glass inner layer fingerprint identification and in-screen fingerprint identification, the key-type fingerprint identification mainly means that a fingerprint identification chip is arranged on a rear panel of the mobile terminal or a Home key of the mobile terminal, the glass inner layer fingerprint identification means that the fingerprint identification chip is arranged on a lower layer of a glass panel of the mobile terminal, and the in-screen fingerprint identification means that the fingerprint identification chip is arranged in a display screen of the mobile terminal. When the fingerprint identification technology in the screen is adopted, the fingerprint icon can be displayed in the area of the display screen provided with the fingerprint identification chip, so that a user can conveniently touch the fingerprint icon in the area to start the fingerprint unlocking function. The method for displaying the fingerprint icon in the screen provided by the embodiment of the disclosure can be used in the application scene, namely, the fingerprint icon is displayed in the area of the display screen provided with the fingerprint identification chip.

In the related art, when the mobile terminal is in a screen-off state, a fingerprint icon is displayed in an area where the fingerprint identification chip is arranged in the mobile terminal in a normally bright mode, and thus, the area is continuously in a screen-on state for a long time, so that serious afterimage and screen burning problems can occur to an OLED display screen.

Next, a method for displaying an on-screen fingerprint icon according to an embodiment of the present disclosure will be described.

Fig. 1 is a flowchart illustrating a method for displaying an on-screen fingerprint icon, which may be used in a mobile terminal, as shown in fig. 1, according to an exemplary embodiment, and includes the following steps.

All the above optional technical solutions can be combined arbitrarily to form optional embodiments of the present disclosure, and the embodiments of the present disclosure are not described in detail again.

In the embodiment of the present disclosure, various sensors may be provided in the mobile terminal, for example, an acceleration sensor, a gravity sensor, a touch sensor, an optical sensor, and the like may be provided, and the mobile terminal may determine a current state of the mobile terminal using different sensors, thereby deciding whether to display a fingerprint icon according to the detected state. An implementation manner in which the mobile terminal detects a current motion state of the mobile terminal using an acceleration sensor and/or a gravity sensor, thereby displaying a fingerprint icon according to the current motion state will be described with reference to fig. 2.

Fig. 2 is a diagram illustrating a method for displaying an on-screen fingerprint icon, which may be applied to a mobile terminal, according to an exemplary embodiment, and as shown in fig. 2, the method includes the steps of:

in step 201, a current motion state of the mobile terminal is detected by an acceleration sensor and/or a gravity sensor provided in the mobile terminal.

In the embodiment of the disclosure, the mobile terminal may detect the current motion state of the mobile terminal through the acceleration collected by the acceleration sensor. The mobile terminal can receive a first acceleration acquired by the acceleration sensor at the current moment, and when the first acceleration is received, the mobile terminal can acquire a second acceleration acquired last time before the current moment; and if the difference value between the first acceleration and the second acceleration is smaller than a first preset value, determining that the current state of the mobile terminal is a static state. If the difference between the first acceleration and the second acceleration is greater than a second preset value, it may be determined that the current state of the mobile terminal is a violent motion state.

Generally, when the mobile terminal is in a severe motion state, there will be a large difference between the acceleration measured by the acceleration sensor at the present moment and the acceleration measured at the last moment. For example, when a user runs with the mobile terminal, there will be a large difference in the acceleration measured by the acceleration sensor at different times. When the mobile terminal is in a stationary state, the acceleration will be kept at a fixed value, that is, the accelerations measured by the acceleration sensor at the current time and the last time will be equal. Further, in consideration of the measurement deviation of the acceleration sensor, even if the accelerations measured at the present time and the previous time are not completely equal, the difference between the two accelerations does not differ too much. Based on this, after the mobile terminal receives the first acceleration, the mobile terminal can acquire a second acceleration acquired by the acceleration sensor at the latest time at the current moment, the first acceleration and the second acceleration are compared, if the difference between the first acceleration and the second acceleration is smaller than a first preset difference, it is indicated that the change of the acceleration of the mobile terminal is small, and at this time, the mobile terminal can be determined to be in a static state. If the difference value between the first acceleration and the second acceleration is larger than a second preset value, the acceleration of the mobile terminal is greatly changed, and at this time, it can be determined that the mobile terminal is in a violent motion state. And if the difference between the first acceleration and the second acceleration is neither less than the first preset value nor greater than the second preset value, it indicates that the mobile terminal is currently moving, but does not belong to a violent movement, that is, in this case, the current state of the mobile terminal is neither a static state nor a violent movement state.

The first preset value may refer to a maximum deviation that may exist in accelerations acquired at two moments before and after the mobile terminal is in a stationary state, and the second preset value may be a minimum difference value, determined through experiments, of the accelerations of the user at the two moments before and after the user holds the mobile terminal to swing the arm during the running process. Of course, the second preset value may also be a minimum difference value of the accelerations of the front and rear time points measured by tests in other severe motion scenes, which is not specifically limited in the embodiment of the present disclosure.

Optionally, in this embodiment of the present disclosure, when the mobile terminal detects the current motion state through the acceleration sensor, after receiving the first acceleration, the mobile terminal may obtain a plurality of second accelerations within a preset time period, and then, the mobile terminal may draw a time variation curve of the plurality of second accelerations and the first angular velocity, so as to determine the current motion state of the mobile terminal according to the time variation curve. Wherein the preset time period is from a certain time before the current time to the current time.

If the plotted change curve is a horizontal straight line, it indicates that the acceleration of the mobile terminal is always a fixed value in the preset time period, and at this time, the mobile terminal may be considered to be in a stationary state. If the obtained change curve fluctuates up and down and the mean value of the difference values between adjacent wave crests and wave troughs is larger than a second preset value, the mobile terminal can be considered to be in a violent motion state.

It should be noted that, in the embodiment of the present disclosure, the mobile terminal may detect the current motion state of the mobile terminal not only through the acceleration sensor, but also through the gravity sensor.

When the mobile terminal detects the current motion state by adopting the gravity sensor, the mobile terminal can receive the gravity components in three directions of a coordinate system established by the mobile terminal and collected by the gravity sensor, then the mobile terminal can obtain the gravity components in three directions collected last time before the current sampling moment, and compare the gravity components in the same direction, if the difference between the gravity components in the same direction is less than a third preset value, the mobile terminal can be determined to be in a static state at present. If any one of the differences between the gravity components in the same direction is greater than a fourth preset value, it may be determined that the mobile terminal is currently in a severe motion state.

Optionally, in a possible case, in order to more accurately determine the current motion state of the mobile terminal, the mobile terminal may also detect the current motion state of the mobile terminal by combining the acceleration sensor and the gravity sensor. For example, if the difference between the first acceleration and the second acceleration is smaller than a first preset difference, and the difference between the two gravity components in each direction is smaller than a third preset value, it may be said that the mobile terminal is currently in a motion state. If the difference between the first acceleration and the second acceleration is greater than a second preset difference, and the difference between two gravity components in any one of the three directions is greater than a fourth preset value, it may be determined that the mobile terminal is currently in a violent motion state.

In step 202, the state of the fingerprint icon is determined based on the current motion state of the mobile terminal.

After determining the current motion state of the mobile terminal, the state of the fingerprint icon may be determined according to the motion state. That is, the mobile terminal may decide whether to display the fingerprint icon in the display screen according to the current motion state.

When the mobile terminal is in a static state, the mobile terminal may be currently placed on a desktop or placed in another place, and at this time, the user may not need to start the fingerprint unlocking function, so that the mobile terminal may not display the fingerprint icon on the display screen, that is, the mobile terminal may determine the state of the fingerprint icon as a non-display state.

When the mobile terminal is in a violent motion state, the user may be in a violent motion state, at this time, on one hand, the user may not need to start the fingerprint unlocking function, and on the other hand, the user may not conveniently perform the fingerprint unlocking, so that, in this case, the mobile terminal may not display the fingerprint icon in the display screen, that is, the state of the fingerprint icon is determined as a non-display state.

When the current state of the mobile terminal is neither a static state nor a violent motion state, because the user is convenient to perform the fingerprint unlocking operation at the moment, and in this case, the possibility that the user needs to start the fingerprint unlocking function is also higher than the possibility of performing the fingerprint unlocking in the static state or the violent motion state, the mobile terminal can display the fingerprint icon on the display screen, that is, the mobile terminal can determine the state of the fingerprint icon as the display state.

It should be noted that, in the embodiment of the present disclosure, the non-display state of the fingerprint icon may refer to that the mobile terminal does not display the fingerprint icon in the display screen in the rest screen state, that is, if the mobile terminal is currently in the standby rest screen state, when it is determined that the state of the fingerprint icon is the non-display state, the mobile terminal may keep the entire display screen in the rest screen state. Similarly, the display state of the fingerprint icon may mean that the rest areas are in a screen-off state when the mobile terminal is in a standby screen-off state, and the fingerprint icon is displayed in the area provided with the fingerprint identification chip. That is, if the mobile terminal is currently in a standby screen-off state, when it is determined that the state of the fingerprint icon is the display state, the mobile terminal may light up an area of the display screen where the fingerprint identification chip is disposed and display the fingerprint icon in the area, and other areas of the display screen are still in the screen-off state.

Further, when the state of the fingerprint icon is determined to be a non-display state, that is, the mobile terminal does not display the fingerprint icon in the screen state, if the user needs to start the fingerprint unlocking function at this time, the user can trigger the mobile terminal to display the fingerprint icon by touching the display screen, that is, after the state of the fingerprint icon is determined to be the non-display state, the mobile terminal can detect whether a touch signal is received or not by the display screen, and if the touch signal is received, the fingerprint icon can be displayed in an area in which the fingerprint identification chip is arranged in the display screen.

In the embodiment of the disclosure, the mobile terminal may detect the current motion state of the mobile terminal through the acceleration sensor and/or the gravity sensor, and determine the state of the fingerprint icon according to the current motion state of the mobile terminal, so that the mobile terminal may display the fingerprint icon when the possibility that a user needs to start an unlocking fingerprint function is high, and may not display the fingerprint icon when the other possibilities are low, thereby satisfying the requirement of convenience of user fingerprint unlocking, and at the same time, effectively reducing the display time of the mobile terminal for displaying the fingerprint icon in the standby process, saving the system power consumption, and effectively improving the problems of display screen afterimage and screen burn caused by displaying the fingerprint icon for a long time.

The above embodiment describes a specific implementation process of detecting the current motion state of the mobile terminal through the acceleration sensor and/or the gravity sensor and determining the state of the fingerprint icon according to the current motion state of the mobile terminal, and next, a specific implementation process of detecting whether the mobile terminal is in a handheld state by using the touch sensor and determining whether to display the fingerprint icon according to the detected current state will be described with reference to fig. 3.

FIG. 3 is a flow chart illustrating a method of displaying an on-screen fingerprint icon in accordance with an exemplary embodiment. The method can be applied to a mobile terminal, as shown in fig. 3, and comprises the following steps:

in step 301, it is detected whether the current state of the mobile terminal is a handheld state through a touch sensor provided in the mobile terminal.

In the embodiments of the present disclosure, the touch sensor may be disposed at a designated position of a side bezel of the mobile terminal. The touch sensor may be a pressure type touch sensor, or may be a capacitance or resistance type touch sensor, wherein the designated position may be determined according to a position that a finger may touch when the user holds the mobile terminal. When a user touches a designated location, a touch sensor located at the designated location may generate a corresponding touch signal.

The mobile terminal can detect a touch signal through the touch sensor, and if the touch signal is detected, the current state of the mobile terminal can be determined to be a handheld state, that is, the mobile terminal is currently held by a user; if the touch signal is not detected, it may be determined that the current state of the mobile terminal is not a handheld state, that is, the user is not currently holding the mobile terminal.

Optionally, in this embodiment of the present disclosure, in order to avoid that the signal detected by the touch sensor is generated by a user's false touch, when the mobile terminal detects the touch signal, the duration of the touch signal may be further determined, if the duration of the touch signal is greater than a preset duration, the current state of the mobile terminal may be determined to be the handheld state, and if the duration of the touch signal is not greater than the preset duration, the current state of the mobile terminal may be considered not to be the handheld state.

In step 302, when the current state of the mobile terminal is the handheld state, the state of the fingerprint icon is determined to be the display state.

When the current state of the mobile terminal is the handheld state, it indicates that the possibility that the user needs to start the fingerprint unlocking function is high at present, and at this time, the mobile terminal may display the fingerprint icon in the area where the fingerprint identification chip is disposed in the display screen, that is, the mobile terminal may determine the state of the fingerprint icon as the display state.

It should be noted that, in the embodiment of the present disclosure, the display state may refer to that the remaining area is in a screen saver state when the mobile terminal is in a standby screen saver state, and the fingerprint icon is displayed in the area where the fingerprint identification chip is disposed. That is, when the mobile terminal is in a standby screen-saving state and the current state of the mobile terminal is determined to be a display state, the area provided with the fingerprint identification chip is lightened, the fingerprint icon is displayed in the area, and other areas of the display screen are still in a screen-saving state.

In step 303, when the current state of the mobile terminal is not the handheld state, the state of the fingerprint icon is determined to be a non-display state.

Considering that a user generally holds the mobile terminal when needing to unlock the fingerprint, when the current state of the mobile terminal is not the held state, it is indicated that the possibility that the user needs to start the fingerprint unlocking function currently is low, and at this time, the mobile terminal may not need to display the fingerprint icon on the display screen, that is, the mobile terminal may determine the state of the fingerprint icon as the non-display state.

It should be noted that the non-display state of the fingerprint icon may refer to that the mobile terminal does not display the fingerprint icon in the display screen in the rest screen state, that is, if the mobile terminal is currently in the standby rest screen state, when it is determined that the state of the fingerprint icon is the non-display state, the mobile terminal may keep the entire display screen in the rest screen state.

In the embodiment of the disclosure, the mobile terminal may detect whether the mobile terminal is in a handheld state through the touch sensor, and if the mobile terminal is in the handheld state, the state of the fingerprint icon is determined to be a display state, otherwise, the state of the fingerprint icon is determined to be a non-display state. Because the possibility that the user carries out fingerprint unlocking in the handheld state of the mobile terminal is far greater than the possibility that the mobile terminal is not in the handheld state, the mobile terminal determines whether to display a fingerprint icon by judging whether the mobile terminal is in the handheld state, the fingerprint icon can be displayed under the condition that the possibility that the user needs to start an unlocking fingerprint function is high, the fingerprint icon is not displayed under the condition that the other possibilities are low, the requirement of convenience of fingerprint unlocking of the user is met, meanwhile, the display time of the mobile terminal for displaying the fingerprint icon in the standby process can be effectively reduced, the system power consumption is saved, and the problems of display screen residual image and screen burn caused by long-time display of the fingerprint icon can be effectively solved.

It should be noted that, in the embodiment of the present disclosure, the mobile terminal may simultaneously combine the acceleration sensor, the gravity sensor and the touch sensor to detect the current state of the mobile terminal. That is, in practical applications, the display method shown in fig. 2 and the display method shown in fig. 3 may be combined to determine whether to display the fingerprint icon. For example, when the mobile terminal detects that the mobile terminal is not in a static state or a violent motion state at present, the mobile terminal can also detect whether the mobile terminal is in a handheld state at present, and if the mobile terminal is in the handheld state at present, the fingerprint icon is displayed. Or, when detecting that the mobile terminal is currently in the handheld state, the mobile terminal may further detect whether the mobile terminal is currently in a violent motion state, and if the mobile terminal is currently in the violent motion state, the fingerprint icon is not displayed. The above are only examples of several combinations given by the embodiment of the present disclosure, and in practical applications, the two manners may be flexibly fused to determine the time when the fingerprint icon needs to be displayed more accurately, so that the display time of the fingerprint icon is reduced, and the display time of the fingerprint icon is more suitable for the user's requirement.

The above embodiment describes a specific implementation process of detecting whether the mobile terminal is in a handheld state by using the touch sensor, and then determining whether to display the fingerprint icon according to the detected current state. Next, a specific implementation of detecting a current state of the mobile terminal using a distance sensor and/or an optical sensor and determining a state of a fingerprint icon according to the detected state will be described with reference to fig. 4.

FIG. 4 is a flowchart illustrating a method of displaying an on-screen fingerprint icon in accordance with an exemplary embodiment. The method can be applied to a mobile terminal, as shown in fig. 4, and comprises the following steps:

in step 401, the current state of the mobile terminal is detected by a distance sensor and/or an optical sensor.

In the embodiment of the present disclosure, a distance sensor and/or an optical sensor may also be provided in the mobile terminal. Through the distance sensor and/or the optical sensor, the mobile terminal can detect whether the mobile terminal is in a shielded state currently.

When the mobile terminal detects the current state by adopting the distance sensor, the mobile terminal can detect the distance between the mobile terminal and the shielding object at the current moment by the distance sensor, and when the distance between the mobile terminal and the shielding object is smaller than the preset distance, the current state of the mobile terminal can be determined to be the shielded state.

Generally, the distance sensor is disposed on a front panel of the mobile terminal and near a top of the mobile terminal, and the distance sensor generally corresponds to an effective detection distance, that is, when a distance between an object and the mobile terminal reaches the effective detection distance, the distance sensor can detect the object, and at this time, the object is called a shelter. Based on this, the mobile terminal can detect whether a shelter exists before the front panel of the mobile terminal through the distance sensor at the current moment, if the shelter exists, the distance sensor can detect the distance between the mobile terminal and the shelter and report the detected distance to the mobile terminal, and the mobile terminal can compare the distance reported by the distance sensor with the preset distance. If the distance detected by the distance sensor is smaller than the preset distance, it indicates that the mobile terminal is shielded by the current shielding object, and at this time, the mobile terminal can determine that the current state is the shielded state. Wherein the preset distance may be smaller than an effective detection distance of the distance sensor.

Further, when the distance between the mobile terminal and the distance sensor is not less than the preset distance, it indicates that the mobile terminal is not blocked by the blocking object at the current time, and at this time, the mobile terminal may further obtain the state of the mobile terminal determined last time before the current time, so as to determine whether the mobile terminal has just been switched from the blocked state to the current non-blocked state. If the acquired state of the mobile terminal determined last time is the blocked state, it may be stated that the blocking object before the mobile terminal is removed at the current time, that is, the mobile terminal is currently in the blocked release state.

Optionally, in the embodiment of the present disclosure, when an optical sensor is disposed in the mobile terminal, the mobile terminal may further detect the current state through the optical sensor.

Generally, when a mobile terminal is shielded, the ambient light level detected by the mobile terminal through an optical sensor will be less than the ambient light level detected when the mobile terminal is not shielded. Based on this, the mobile terminal may detect the current ambient light brightness through the optical sensor, and when the detected brightness is less than the preset brightness, it may be determined that the current state of the mobile terminal is the blocked state. Otherwise, it may be determined that the mobile terminal is currently in a non-occluded state. The preset brightness may be different according to the current time. For example, the preset brightness will be different when the current time is day and the current time is night. And, the preset brightness may be a minimum average brightness when the mobile terminal is not occluded, which is determined through experiments in different scenes.

Optionally, in order to more accurately determine the current state of the mobile terminal, the mobile terminal may further employ a distance sensor and an optical sensor to determine whether the mobile terminal is currently in an occluded state. For example, if the distance between the shielding object detected by the distance sensor and the mobile terminal is less than the preset distance, and the current ambient light brightness detected by the optical sensor is less than the preset brightness, the mobile terminal may determine that the mobile terminal is currently in the shielded state. If the distance between the shelter detected by the distance sensor and the mobile terminal is not less than the preset distance, or the current ambient light brightness detected by the optical sensor is not less than the preset brightness, the mobile terminal can determine that the mobile terminal is in a non-sheltered state. The above are only examples of several combinations given by the embodiments of the present disclosure, and in practical applications, the two sensors may be flexibly fused to determine the current state of the mobile terminal more accurately, so as to provide a more accurate basis for determining the state of the fingerprint icon.

In step 402, the state of the fingerprint icon is determined based on the current state of the mobile terminal.

When the mobile terminal determines that the current state is the blocked state, the mobile terminal may be currently in a user call state, or placed in a user pocket or bag, or the mobile terminal may be held in the hand of the user with the front panel facing the palm of the user, or may be in other blocked scenes. Under the above scenario, the possibility that the user needs to perform fingerprint unlocking is often low, and based on this, the mobile terminal may determine the state of the fingerprint icon as a non-display state, that is, under the condition that the mobile terminal is waiting for screen saving, the whole display screen of the mobile terminal may be kept in a screen saving state.

Further, when the mobile terminal determines that the current state is the shielding release state, considering that in a daily use scene, the mobile terminal is switched from the shielded state to the shielding release state, that is, the time when the user removes the shielding object before the mobile terminal, at this time, the possibility that the user needs to perform fingerprint unlocking is high, therefore, the mobile terminal may set the state of the fingerprint icon to the display state, that is, the mobile terminal may light up the area of the display screen where the fingerprint identification chip is disposed and display the fingerprint icon in the area, while the other areas of the display screen are still in the screen-saving state.

In the embodiment of the disclosure, the mobile terminal may detect whether the current state of the mobile terminal is a blocked state through the distance sensor and the optical sensor, when the current state of the mobile terminal is the blocked state, the mobile terminal may determine the state of the fingerprint icon as a non-display state, when the current state of the mobile terminal is not the blocked state, the mobile terminal may further determine whether the current state is a blockage-released state, and if the current state is the blockage-released state, the state of the fingerprint icon may be determined as a display state. Because the mobile terminal has low possibility of fingerprint unlocking by a user in a shielded state and has high possibility of fingerprint unlocking in a shielding release state, namely shielding release moment, accordingly, the mobile terminal can determine whether to display the fingerprint icon by determining whether the mobile terminal is in an occluded state and in an occlusion release state, and thus, it can be ensured that the fingerprint icon is displayed in case the user has a high probability of needing to activate the unlock fingerprint function, and is not displayed in case the remaining probability is low, the method has the advantages that the requirement of convenience for unlocking the fingerprint of the user is met, meanwhile, the display time of the fingerprint icon displayed by the mobile terminal in the standby process can be effectively reduced, the system power consumption is saved, and the problems of display screen image retention and screen burning caused by long-time display of the fingerprint icon can be effectively solved.

It should be noted that, in the embodiment of the present disclosure, the mobile terminal may simultaneously combine an acceleration sensor, a gravity sensor, a touch sensor, a distance sensor, and an optical sensor to detect the current state of the mobile terminal. That is, in practical applications, the display methods shown in fig. 2, 3 and 4 may be combined to determine whether to display the fingerprint icon more accurately. The specific combination mode may be flexibly combined according to different needs of different scenarios, and the embodiment of the present disclosure is not specifically limited herein.
