Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
Fig. 1 is a schematic flowchart of a fingerprint identification method according to an embodiment of the present disclosure. The fingerprint identification method is suitable for guiding a user to unlock the fingerprint by displaying the fingerprint icon after the display screen is turned off, can be executed by a fingerprint identification device, can be realized by software and/or hardware, and can be generally integrated in electronic equipment. As shown in fig. 1, the fingerprint identification method includes:
and 110, when the display screen of the intelligent terminal is turned off, controlling the intelligent terminal to enter a screen turn-off state, wherein the screen turn-off state comprises the sleep of the display module, the closing of the fingerprint module and the opening of the touch module.
In the embodiment of the present disclosure, the display screen of the intelligent terminal may include a liquid crystal display screen or an organic light emitting diode display screen. For example, when the display screen includes a liquid crystal display screen, the display module may include a display driving unit and a backlight module, and when the display screen includes an organic light emitting diode display screen, the display module may include a display driving circuit and an organic light emitting diode. When the display module is in sleep, the display module does not receive display data and is in a low-power-consumption running state, and meanwhile, the display module can be awakened quickly when in sleep, so that the instant display of the picture is realized. In addition, the fingerprint module may include a fingerprint driving unit and a fingerprint sensor, and the fingerprint sensor may include an optical fingerprint sensor, a semiconductor fingerprint sensor, an ultrasonic fingerprint sensor, or the like; the touch module can comprise a touch chip and a touch electrode, and can realize a capacitive touch screen or a resistive touch screen, wherein the touch electrode can be embedded or hung externally.
According to the embodiment, when the display screen of the intelligent terminal is turned off, the display module of the intelligent terminal is controlled to enter the sleep state, namely when the display screen of the intelligent terminal is turned off, the displayed fingerprint icon can be turned off immediately, and the phenomenon that the intelligent terminal is power-consumptive seriously due to the fact that the displayed fingerprint icon after the screen is turned off is displayed or is turned off in a delayed mode is avoided. Meanwhile, the fingerprint module is closed to further reduce power consumption, and the touch module is opened to perform touch detection in real time, so that the display module is awakened according to touch operation of a user when the user performs fingerprint unlocking.
And 120, if the first touch operation is detected in the set area of the display screen, waking up the display module and displaying a fingerprint icon in the fingerprint identification area through the display module, wherein the set area is a partial area of the display screen and comprises the fingerprint identification area.
After the screen of the display screen is turned off, if the user lights the display screen through fingerprint unlocking, the problem that the user cannot accurately sense the fingerprint identification area exists, the user may be required to touch the display screen for multiple times to enable the fingerprint module to identify the fingerprint, and the user experience is reduced. Therefore, the scheme guides the user to perform fingerprint identification operation in a mode of displaying the fingerprint icon in the fingerprint identification area aiming at the screen turn-off condition of the display screen, so that the user can accurately determine the fingerprint identification area.
Specifically, referring to fig. 2, in the present embodiment, a setting area 100 is designed on the display screen 1, and the user touches the setting area 100 (i.e., a first touch operation) to trigger the display of the fingerprint icon. And the setting area 100 is a partial area of the display screen 1 and includes the fingerprint identification area 200, so that the touch position is considered as the user's intention to perform the fingerprint identification operation only when approaching or being located in the fingerprint identification area 200, and at this time, the display module is awakened and the fingerprint icon is displayed in the fingerprint identification area 200 through the display module. The fingerprint icon is effectively prevented from being lightened by mistakenly touching the display screen when the user does not need to unlock the fingerprint, so that the power consumption of the intelligent terminal is further reduced; meanwhile, as soon as the user touches the set area of the display screen, the intelligent terminal immediately responds to display the fingerprint icon, the response speed of the intelligent terminal is reduced, and the user experience is improved.
Fig. 2 schematically shows only one case of the setting area 100 and the fingerprint identification area 200, the fingerprint identification area 200 is specifically determined according to an actual detection range of the fingerprint module, an outer edge of the setting area 100 is arranged around an outer edge of the fingerprint identification area 200, the shape of the outer edge of the setting area 100 is not limited to a circle, and may be a regular pattern such as a triangle or a quadrangle, or other irregular patterns, and the shape of the irregular pattern is not limited by the present disclosure; meanwhile, the size of the setting area 100 is not limited in the present disclosure, as long as it is a partial area of the display screen 1 and includes the fingerprint identification area 200. Specifically, in some embodiments of the present disclosure, the minimum distance from the outer edge of the defined area 100 to the outer edge of the fingerprint identification area 200 is less than or equal to 1 centimeter. Thus, in consideration of an error in which the user perceives the fingerprint recognition area, when it is ensured that the touch operation by the user can trigger the display of the fingerprint icon, the range of the setting area 100 is narrowed, that is, the area of the other area is relatively increased, and the probability of displaying the fingerprint icon due to the erroneous touch is reduced, thereby further reducing power consumption. In addition, the fingerprint icon can be any figure, such as a fingerprint figure.
In order to further determine whether the user needs to perform fingerprint identification operation and save power consumption of the intelligent terminal, the scheme continues to detect whether the fingerprint identification area has second touch operation. And if the second touch operation is detected in the fingerprint identification area, determining that the user needs to perform the fingerprint identification operation, and opening the fingerprint module to identify the fingerprint of the user.
Particularly, when whether a first touch operation exists in the setting area is detected, if the first touch operation is detected to occur in the fingerprint identification area, the first touch operation is also determined as a second touch operation, and the fingerprint module is turned on while the display module is awakened, so that the time for the user to perform the fingerprint identification operation is reduced.
In the embodiment, when the display screen of the intelligent terminal is turned off, the display module is controlled to enter a sleep state, the fingerprint module is turned off, and the touch module is turned on to detect touch operation, so that only touch detection is performed when the intelligent terminal is turned off, and the power consumption of the intelligent terminal is reduced; after the intelligent terminal is turned off, if a first touch operation is detected in a partial area of the display screen, which comprises a fingerprint identification area, the display module is awakened and the fingerprint icon is displayed in the fingerprint identification area through the display module, so that the fingerprint icon is displayed only when a user touches the fingerprint identification area and an area near the fingerprint identification area, the fingerprint icon is effectively prevented from being lightened due to mistaken touch of the display screen when the user does not need fingerprint unlocking, and the power consumption of the intelligent terminal is further reduced; meanwhile, as soon as the user touches a set area of the display screen, the intelligent terminal immediately responds to display the fingerprint icon, so that the response speed of the intelligent terminal is reduced, and the user experience is improved; in addition, after the fingerprint icon is displayed, the user can be guided to accurately determine the fingerprint identification area, and at the moment, if the second touch operation is detected in the fingerprint identification area, the fingerprint module is opened, so that the fingerprint module is opened after the user touches the fingerprint identification area, and the power consumption of the intelligent terminal is further reduced.
Fig. 3 is a schematic flowchart of another fingerprint identification method according to an embodiment of the present disclosure. Based on the above embodiments, the present embodiment optimizes the above embodiments. Optionally, the method further includes: and if the first touch operation in the set area is not detected, keeping the screen-off state. Therefore, the display module is ensured to be awakened only when the first touch operation is detected in the set area, and redundant power consumption is avoided. Further, this embodiment further includes: after the fingerprint icon is displayed, if a second touch operation in the fingerprint identification area is not detected within a set time, the intelligent terminal is controlled to enter a screen-off state. Therefore, the first touch operation can be judged to be mistaken touch, the displayed fingerprint icon is turned off, the intelligent terminal returns to the screen turn-off state, and power consumption of the intelligent terminal is reduced.
Correspondingly, based on the above technical solution, in a specific embodiment of the present disclosure, as shown in fig. 3, the fingerprint identification method includes:
and step 210, controlling the intelligent terminal to enter a screen-off state when the display screen of the intelligent terminal is turned off.
If yes, go to step 230; otherwise, step 260 is performed.
When the first touch operation is not detected in the set area of the display screen, even if the touch operation is detected in other areas, the user is considered not to have the intention of fingerprint identification operation, and the possibility that the user touches the display screen by mistake is eliminated.
And step 230, waking up the display module and displaying the fingerprint icon in the fingerprint identification area through the display module.
And step 240, after the fingerprint icon is displayed, whether a second touch operation in the fingerprint identification area is detected within a set time is determined.
If yes, go to step 250; otherwise, step 270 is performed.
The setting time can be set by itself, the setting time can be 2 seconds by combining the reaction time of a user when the user looks up the fingerprint icon, namely, after the first touch operation, the display screen displays the fingerprint icon, when the display duration of the fingerprint icon reaches 2 seconds, the second touch operation is not detected, the display of the fingerprint icon is closed, the intelligent terminal is controlled to enter a screen-off state, and the power consumption of the intelligent terminal is further reduced.
In some embodiments of the present disclosure, the first touch operation and the second touch operation are the same continuous touch operation. Namely, from the first touch operation to the second touch operation, the user finger does not leave the display screen, namely, the first touch operation and the second touch operation constitute a sliding operation. From this, when the user touched the peripheral region (peripheral region is located the set area) of fingerprint identification area (peripheral region when detecting that the set area has first touch operation promptly), intelligent terminal awakens up display module, show the fingerprint icon through display module, at this moment, the user only need with the finger slide to the fingerprint icon (be the fingerprint identification area), can make intelligent terminal open the fingerprint module and carry out fingerprint identification, and need not that the user lifts up and just can demonstrate the fingerprint icon after pointing, so that the user need touch the fingerprint icon once more and carry out fingerprint identification, thereby user experience has been promoted.
And step 260, keeping the screen-off state.
And 270, controlling the intelligent terminal to enter a screen-off state.
In addition, in some embodiments of the present disclosure, the fingerprint identification method may further include:
and if the intelligent terminal is determined to be placed in a pocket or a bag based on the sensor of the intelligent terminal, controlling the display module to enter a sleep state or closing the touch module. From this, this embodiment of the disclosure combines the scheme of fingerprint icon demonstration, a technical scheme that pocket was prevented mistake and is touched is provided, put in pocket or package after putting out the screen when intelligent terminal's display screen promptly, through control display module entering sleep state or close touch module, even material such as user's clothing or user finger touch the settlement region of display screen, can not show the fingerprint icon yet, and then when reducing intelligent terminal power consumptive, avoid intelligent terminal's display screen to be lighted because of mistake is touched, further reduce subsequent maloperation.
In this scenario, the sensor may include an infrared distance sensor and/or a photoelectric proximity sensor, and for example, the sensor based on the smart terminal determines that the smart terminal is placed in a pocket or a bag, including:
acquiring data acquired by an infrared distance sensor and/or a photoelectric proximity sensor;
and if the data is smaller than the set value, determining that the intelligent terminal is placed in a pocket or a bag.
In the above scheme, the data acquired by the infrared distance sensor and/or the photoelectric proximity sensor includes distance data, and when the distance data is judged to be smaller than a set value, it can be determined that the infrared distance sensor and/or the photoelectric proximity sensor is shielded, that is, the intelligent terminal is placed in a small space, so that it is determined that the intelligent terminal is placed in a pocket or a bag.
