Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a terminal unlocking method according to an exemplary embodiment, where the terminal unlocking method according to the exemplary embodiment is used in a terminal device (e.g., a smartphone), as shown in fig. 1, and includes the following steps.
In step S11, in the case where the locked terminal is started, it is detected whether the fingerprint information collection area of the screen is pressed;
in step S12, in the case where it is detected that the fingerprint information collection area of the screen is pressed, controlling the screen backlight and collecting fingerprint information;
in step S13, in the case where the acquired fingerprint information reaches the unlock condition, the locked terminal is unlocked.
According to the method, the locked terminal is unlocked by controlling the screen to be backlight and collecting the fingerprint information under the condition that the locked terminal is started and the fingerprint collecting area of the screen is pressed.
In one possible implementation, the locked terminal may be the terminal device itself, for example, the terminal device in a screen-locked state; for example, for an application, a user may set an encryption operation such as a fingerprint or a gesture to the application when the application is used last time, and when the application is started again, if an unlocking condition matching information such as a fingerprint or a gesture set by the user is not detected, the application is in a locked state, and the application may be regarded as a locked terminal.
In a possible implementation manner, the fingerprint information collection area may be the whole screen or a certain area in the screen, for example, a fingerprint collection module capable of collecting fingerprint information may be disposed below the screen, and the fingerprint information collection area is set to collect the fingerprint information in the whole screen or the certain area in the screen, wherein the fingerprint collection and identification may be performed in an optical manner.
In a possible implementation manner, in a case that a locked terminal is started, whether a fingerprint information acquisition area of a screen is pressed is detected, for example, whether a terminal device or an application in the terminal device is in a locked state may be detected by detecting whether the screen at the fingerprint information acquisition area is deformed; it is also possible to detect whether the fingerprint information collection area of the screen is pressed based on the principle of a touch screen. The method for detecting whether the fingerprint information acquisition area of the screen is pressed does not limit the method.
Fig. 2 is a flowchart illustrating a terminal unlocking method according to an exemplary embodiment. As shown in fig. 2, in one possible implementation, step S12 may include:
in step S121, in the case where it is detected that the fingerprint information collection area of the screen is pressed, the screen backlight is controlled to be turned off and on at first time intervals.
For example, when it is detected that the fingerprint information collection area of the screen is pressed, the screen backlight may be controlled to be turned off and on at a first time interval, for example, the first time interval may be set to 0.1s, the screen backlight may be controlled to be turned off in the first 0.1s, the screen backlight may be controlled to be turned on in the second 0.1s, the screen backlight may be controlled to be turned off in the third 0.1s, and the screen backlight may be controlled to be turned on in the fourth 0.1s, and the above operations may be repeatedly performed, and fingerprint information may be collected during the process of controlling the screen backlight.
By controlling the closing and opening of the screen backlight, the fingerprint information can be collected based on the backlight condition of the screen, and the accuracy of the collected fingerprint information is improved.
Fig. 3 is a flowchart illustrating a terminal unlocking method according to an exemplary embodiment, and as shown in fig. 3, in a possible implementation manner, the step S12 may further include:
in step S122, in the case that the screen backlight is turned off, collecting first fingerprint information;
in step S123, when the first fingerprint information is collected for the first collection number of times, the superposed first fingerprint information is used as the fingerprint information.
For example, in the process of controlling the screen backlight to be turned off and on at a first time interval, fingerprint information may be collected and used as the first fingerprint information when the screen backlight is turned off, fingerprint information may not be collected when the screen backlight is turned on, and the superimposed first fingerprint information may be used as the fingerprint information when the first fingerprint information is collected for a first collection time (e.g., 8 to 12 times). To determine whether to unlock the locked terminal based on the fingerprint information.
In one possible implementation, the screen is a TFT display screen.
This embodiment, under the condition that the fingerprint information collection area that detects the screen is pressed, be shaded through control screen and close and open with time interval, and be shaded under the condition of closing at the screen, gather first fingerprint information, avoided because be shaded to fingerprint information collection's influence, improved the accuracy of the fingerprint information who gathers. In addition, the screen backlight is controlled to be turned off and on at the first time interval, in other words, if the first time interval can be controlled to be short, since the human eye is limited by the resolution, the user may not be able to perceive the change of brightness of the screen of the terminal device in a short time. Moreover, if the screen is a TFT display screen, the fingerprint information in the screen can be collected and identified, in other words, the fingerprint collecting area can be contained in the screen, and on one hand, a user can collect the fingerprint information in the using process; on the other hand, the area of the screen can be increased.
Fig. 4 is a flowchart illustrating a terminal unlocking method according to an exemplary embodiment, and as shown in fig. 4, in one possible implementation, step S13 may include:
in step S131, in the case where the matching degree of the collected fingerprint information and the unlocking information is greater than or equal to the first threshold, it is determined that the collected fingerprint information reaches the unlocking condition.
For example, the matching degree between the fingerprint information collected in step S12 and the unlocking information may be compared, and in the case that the matching degree between the collected fingerprint information and the unlocking information is greater than or equal to a first threshold (e.g., 50% -80%), it may be determined that the collected fingerprint information reaches the unlocking condition, so as to unlock the locked terminal.
In a possible implementation manner, in a case that the matching degree of the acquired fingerprint information and the unlocking information is smaller than the first threshold, it is determined that the acquired fingerprint information cannot reach the unlocking condition, and the step returns to step S11 to judge whether the acquired fingerprint information can reach the unlocking condition again.
The acquired fingerprint information is matched with the unlocking information, and the acquired fingerprint information is determined to reach the unlocking condition under the condition that the matching degree is greater than or equal to the first threshold value, so that the locked terminal can be unlocked more quickly.
In an application scene, taking a locked terminal as an example, when a user starts an application, the user can press a finger on a fingerprint information acquisition area of a screen, when the terminal device detects that the fingerprint information acquisition area of the screen is pressed, the terminal device can control the backlight of the screen to be turned off and on at a first time interval, when the screen is turned off, first fingerprint information is acquired, when the acquired first fingerprint information reaches a first acquisition frequency, the overlapped first fingerprint information is used as fingerprint information, and the fingerprint information is matched with unlocking information. If the matching degree of the fingerprint information and the fingerprint information is larger than or equal to a first threshold value, determining that the acquired fingerprint information meets an unlocking condition, and unlocking the application; if the matching degree of the two is less than the first threshold, it is determined that the acquired fingerprint information cannot reach the unlocking condition, in which case the steps S11-S13 may be re-executed. The method can also be applied to the situation that the locked terminal is the terminal equipment, and the screen of the terminal equipment can be lightened firstly, and then the terminal equipment is unlocked according to the steps.
In another application scenario, taking a locked terminal as an example of a terminal device, when the backlight of a screen is off, a user may press a finger on a fingerprint information acquisition area of the screen, when the terminal device detects that the fingerprint information acquisition area of the screen is pressed, the backlight of the screen may be controlled to be continuously turned off and fingerprint information is acquired, and when the matching degree of the acquired fingerprint information and unlocking information is greater than or equal to a first threshold, it is determined that the acquired fingerprint information reaches an unlocking condition, and the terminal device is unlocked.
The embodiment can unlock the terminal device and also unlock the application, and the type of the screen is not limited by the AMOLED display screen or the TFT display screen because the fingerprint information is collected by controlling the backlight of the screen, and the accuracy of collecting the fingerprint information can be improved under the condition of adopting the TFT display screen, so that the convenience of user operation is enhanced, and the user experience is improved. In addition, if the first time interval is set below the resolution of human eyes, the human eyes cannot perceive the turning-off and turning-on of the backlight, and the user experience cannot be affected.
