Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
The following describes a power saving control method and device for an off-screen fingerprint, and an electronic device according to an embodiment of the present application with reference to the drawings.
Fig. 1 is a flowchart of a power saving control method of an off-screen fingerprint according to an embodiment of the present application.
As shown in fig. 1, the power saving control method for the off-screen fingerprint includes:
s101, controlling the display screen to be turned off and entering a standby state.
At present, the fingerprint technology under the screen cancels the physical fingerprint identification key, and if a user wants to unlock the screen, the user needs to light the fingerprint identification area of the screen first, for example, a circular fingerprint pattern is displayed at a position lower than the screen, and the fingerprint pattern corresponds to the fingerprint identification area. The fingerprint identification area is lighted up, and a user can perform fingerprint verification by clicking the area with a finger. However, the mechanism for lighting the fingerprint identification area is mainly to light the fingerprint identification area by detecting the shake generated by the electronic device through the acceleration sensor. The mechanism is easy to generate false triggering, for example, when a user walks or runs, no matter the user holds the electronic equipment or places the electronic equipment in a bag, the electronic equipment can shake, and therefore a fingerprint identification area is automatically lightened. In fact, in this scenario, the user does not have a need to unlock the screen. The fingerprint identification area is frequently lighted up, increasing the power consumption of the mobile phone. Therefore, the power saving control method for the fingerprint under the screen can prevent false triggering and save power consumption.
In one embodiment of the present application, the display screen may be controlled to go off and enter a standby state. That is, when the user does not use the electronic device, the user can control the display screen to be turned off by triggering the switch button of the electronic device, and simultaneously enter the standby state. Of course, it may also be that when a period of time elapses and the electronic device does not receive any operation, the electronic device automatically controls the display screen to be turned off and enters the standby state.
And S102, controlling the fingerprint identification area of the display screen to be lightened in a standby state.
After entering the standby state, the fingerprint identification area of the display screen can be controlled to be lightened, namely, although the display screen is extinguished, the fingerprint identification area in the display screen is lightened.
S103, judging whether the direction faced by the display screen is upward or not.
After the fingerprint identification area of the display screen is controlled to be lightened, whether the direction faced by the display screen is upward or not can be judged, namely, whether the direction faced by the front face of the display screen is upward or not can be judged.
Particularly, the included angle between the inclination angle of the display screen and the horizontal plane can be acquired through the acceleration sensor, then the included angle is compared with a preset angle, and whether the included angle is smaller than the preset angle or not is judged. If the included angle is smaller than the preset angle, the direction faced by the display screen can be determined to be upward; and if the included angle is larger than the preset angle, determining that the direction faced by the display screen is not upward. As shown in fig. 2, the display screen may be completely horizontally upward, i.e. the angle between the inclination angle of the display screen and the horizontal plane is 0 degrees. When the display screen is inclined, the display screen can be respectively inclined towards four directions, namely left and right inclination and up and down inclination. If the preset angle is 45 degrees, if the included angle is smaller than 45 degrees, the display screen faces upward, otherwise, the display screen faces other directions.
And S104, if the direction faced by the display screen is upward, further judging whether the display screen shakes within a preset time period.
If the display screen faces upwards, the next judging step can be carried out, namely whether the display screen shakes within a preset time period. For example, within 5 seconds, the acceleration sensor detects whether the display screen shakes.
S105, if the display screen shakes, keeping the fingerprint identification area on.
Under the condition that the direction faced by the display screen is upward, if the display screen shakes within a preset time period, the user still needs to use the electronic equipment, and the fingerprint identification area can be kept on for the user to trigger and unlock the screen fingerprint.
S106, if the display screen does not shake, controlling the fingerprint identification area to be extinguished.
And if the shaking of the display screen is not detected within the preset time period, the fact that the user does not have the requirement of continuously using the electronic equipment can be determined, the fingerprint identification area can be controlled to be turned off, and the complete screen turning-off is realized.
In another embodiment of the present application, as shown in fig. 3, the power saving control method for the off-screen fingerprint may further include:
s107, if the direction faced by the display screen is not upward, controlling the fingerprint identification area to be extinguished.
When a user uses an electronic device, the display screen is in an upward state in most cases. That is to say, the embodiment of the application determines the requirement of the user for using the electronic device by determining whether the direction faced by the display screen is upward. If the display screen is not upward, the requirement that the current user does not use the electronic equipment is indicated, and then the fingerprint identification area can be directly controlled to be turned off, so that the power consumption is saved.
The power saving control method of the fingerprint under the screen of the embodiment of the application, extinguish through controlling the display screen, enter the standby state, and in the standby state, the fingerprint identification area of the control display screen is lightened, judge whether the direction that the display screen faces is upwards again, if the direction that the display screen faces is upwards, further judge whether in the preset time period, whether the display screen shakes, if the display screen shakes, keep the fingerprint identification area to lighten, can intelligently judge whether the user has the demand of using the electronic equipment, and then control the fingerprint identification area to lighten or extinguish, prevent the condition of generating false triggering, and save the power consumption.
In another embodiment of the present application, as shown in fig. 4, the power saving control method for the off-screen fingerprint may further include:
and S108, judging whether the display screen is shielded or not before judging whether the direction faced by the display screen is upward or not.
In order to further improve the efficiency of preventing false triggering, whether the display screen is shielded or not can be judged before judging whether the direction faced by the display screen is upward or not. Wherein, whether the display screen is sheltered from can be detected through infrared sensor.
And S109, if the display screen is blocked, controlling the fingerprint identification area to be extinguished.
If the display screen is shielded, the electronic equipment is possibly placed in the bag, and the fingerprint identification area is directly controlled to be turned off without responding to subsequent judgment logic, so that the power consumption is further saved.
If the display screen is not blocked, the process goes to step S103, i.e. it is determined whether the direction faced by the display screen is upward.
In yet another embodiment of the present application, as shown in fig. 5, the power saving control method for the off-screen fingerprint may further include:
s501, after the display screen is controlled to be turned off and enters a standby state, whether the display screen turns on a screen turn-off clock or not is judged.
The screen-off clock function is a function which can still display time in the interface after screen-off in a standby state.
And S502, if the screen-off clock is started on the display screen, controlling the fingerprint identification area to be constantly on.
In a standby state, if the screen-off clock is started on the display screen, time can be displayed in the interface after the screen is turned off, and meanwhile, the fingerprint identification area is kept normally bright. The fingerprint identification area can be displayed simultaneously while the service of displaying time is provided for the user, and the user can conveniently unlock the screen fingerprint.
And if the screen-off clock is not started on the display screen, jumping to step S102, and controlling the fingerprint identification area to be lightened.
