First embodiment

In order to solve the problem that the power consumption of a terminal is too large and user experience is affected because a fingerprint identification module in an existing whole under-screen fingerprint identification area is always in an awake state, the present embodiment provides an under-screen fingerprint power consumption control method, as shown in fig. 3, fig. 3 is a basic flow chart of the under-screen fingerprint power consumption control method provided by the present embodiment, and the under-screen fingerprint power consumption control method includes:

s301, dividing an under-screen fingerprint identification area of the terminal into at least two sub-areas.

The terminal comprises a display screen, a fingerprint identification module, a controller, an induction sensor, an infrared emitter and an infrared receiver, wherein the fingerprint identification module is distributed below the display screen of the terminal; when the touch of finger is detected by the induction sensor, the controller controls the infrared transmitter and the infrared receiver to work, the infrared transmitter transmits light, the light is reflected by the surface of the fingerprint and received by the infrared receiver, and then the fingerprint identification is carried out. In this embodiment, the fingerprint identification is regional under the screen and is used for discerning user's fingerprint information, and fingerprint identification is regional under the screen promptly and is provided with a plurality of fingerprint identification modules. Of course, the area for identifying the fingerprint under the screen may be the entire display screen or a partial area of the touch display screen, which is not limited herein.

It should be understood that, the sub-screen fingerprint identification area is divided into at least two sub-areas, which is essentially a fingerprint identification module that divides a fingerprint identification module under the sub-screen fingerprint identification area into at least two sub-areas, and the sub-area may be divided according to an operation area of a fingerprint identification operation, for example, when the fingerprint identification operation is performed through the sub-screen fingerprint identification area within a first preset historical time period, an operation position corresponding to each fingerprint identification operation in the sub-screen fingerprint identification area is obtained, and the operation position is divided into at least two different areas according to a similarity degree, so as to obtain at least two sub-areas, where the closer the two operation positions are, the greater the similarity degree is, it should be noted that the obtained sub-area may be a regular area, such as a rectangular area, or an irregular area. Namely, when the user uses the fingerprint for unlocking or verification each time, the fingerprint identification operation can be executed, such as pressing, clicking and the like, the operation position of the fingerprint identification area under the screen in each fingerprint identification operation in the first preset historical time period is obtained and recorded, the operation positions of all the fingerprint identification operations in the first preset historical time period are counted, and the operation positions are divided into at least two different areas according to the similarity degree. For example, as shown in fig. 4, the underscreen fingerprint identification area is an area enclosed by a dashed-line frame, the pressing positions of the user in each underscreen unlocking in the latest day are 401, 402, 403, 404, and 405, respectively, the cluster analysis is performed on the 5-time pressing positions, and the underscreen fingerprint identification area is divided into three sub-areas, 406, 407, and 408, respectively.

In some embodiments, the under-screen fingerprint identification area of the terminal is divided into at least two sub-areas, which may also be divided according to a preset division rule; for example, the under-screen fingerprint identification area is divided into at least two sub-areas by taking the preset size as a unit, the under-screen fingerprint identification area can be uniformly divided into at least two sub-areas, that is, the size of each sub-area is equal, or the under-screen fingerprint identification area can be randomly divided into at least two sub-areas, that is, the size of each sub-area has no unified standard. The preset size can be a square with the side length being the preset size or a circle with the radius being the preset size; the preset size can be regular patterns such as a standard square, a standard circle and the like; for example, as shown in fig. 5, an off-screen fingerprint identification area 502 is uniformly divided into 6 sub-areas in units of a square 501 having a side length of 2 cm. As shown in fig. 6, the underscreen fingerprint identification area 601 is randomly divided into 4 sub-areas in units of standard circles having a radius of 1cm, where the sub-area 602 is a set of 3 standard circles, the sub-area 603 is a set of 5 standard circles, the sub-area 604 is a set of 6 standard circles, and the sub-area 605 is a set of 8 standard circles. Certainly, the division according to the preset division rule may also be performed by taking a lower end edge line of the terminal display screen as a reference line, dividing the under-screen fingerprint identification area into two sub-areas according to a standard line which is a preset distance from the reference line, where the preset distance may be flexibly adjusted according to the requirement of the user, and optionally, the preset distance is slightly greater than the length of a finger knuckle of the user, for example, as shown in fig. 7, the under-screen fingerprint identification area is the whole display screen, the reference line is 701, the standard line which is 3cm from the reference line is 702, and the under-screen fingerprint identification area is divided into two sub-areas according to the standard line 702, which are respectively a first sub-area 703 and a second sub-area 704. It should be noted that the preset division rule may also be that the under-screen fingerprint identification area is divided into at least four sub-areas according to a cross structure.

S302, selecting corresponding wake-up modes from the wake-up mode library for each sub-area respectively for configuration.

It should be noted that, in this embodiment, the wake mode library includes at least two different wake modes, and the wake time intervals corresponding to the different wake modes are different. For example, the wake-up mode includes a first wake-up mode and a second wake-up mode, where a wake-up time interval of the first wake-up mode is equal to zero, that is, the first wake-up mode is a long wake-up mode, that is, the fingerprint identification module is always in the wake-up mode; the wake-up time interval of the second wake-up mode is greater than zero, and according to the difference of the wake-up time intervals, the second wake-up mode further includes a third wake-up mode, a fourth wake-up mode … …, an nth wake-up mode, and the like, where the wake-up time intervals of the third wake-up mode and the fourth wake-up mode … … are different from each other, where specific values of the wake-up time intervals may be flexibly adjusted according to actual use conditions, for example, the wake-up time interval of the third wake-up mode is 5s, the wake-up time interval of the fourth wake-up mode is 8s, and the wake-up time interval of the fifth wake-up mode is 11s … ….

In this embodiment, when the fingerprint identification area under the screen is divided into at least two sub-areas, the selection modes of the wake-up modes of the fingerprint identification modules in the sub-areas are different according to the different dividing modes. When the fingerprint identification area under the screen is divided according to the operation area of the fingerprint identification operation, selecting a corresponding wake-up mode from the wake-up mode library for each sub-area to configure, wherein the configuration comprises acquiring the operation frequency of each sub-area in a second preset historical time period, and acquiring the operation times of a user for unlocking or verifying the fingerprint of each sub-area in the second preset historical time period when the fingerprint identification operation is performed through the fingerprint identification area under the screen, wherein the second preset historical time period can be the same as or different from the first preset historical time period; and matching the operation frequency with a preset operation frequency and awakening mode corresponding relation table in the awakening mode library, selecting the awakening mode corresponding to the operation frequency, and configuring according to the selected awakening mode. It can be understood that the wake-up mode library further includes a table of correspondence between preset operating frequencies and wake-up modes, where the correspondence between the preset operating frequencies and the wake-up modes may be that one operating frequency corresponds to one wake-up mode; or one operation frequency range section corresponds to one awakening mode, and the specific corresponding relation can be flexibly adjusted according to actual requirements. As shown in table 1, table 1 is a table of correspondence between a preset operating frequency range segment and an awake mode provided in this embodiment. For example, in the last week, the operation frequency of acquiring the sub-region 407 in fig. 4 is 20 times, the operation frequency of the sub-region 408 in fig. 4 is 12 times, and the operation frequency of the sub-region 406 in fig. 4 is 4 times, each time the user uses the fingerprint under the screen to unlock; that is, the operation frequency of the sub-area 407 is 5/9, the operation frequency of the sub-area 408 is 4/9, and the operation frequency of the sub-area 406 is 1/9, and as shown in table 1, the first wake-up mode is selected to configure the fingerprint identification module of the sub-area 407, the third wake-up mode is selected to configure the fingerprint identification module of the sub-area 408, and the fourth wake-up mode is selected to configure the fingerprint identification module of the sub-area 406.

In some embodiments, when the under-screen fingerprint identification area is divided into at least two sub-areas according to a preset division rule, each sub-area corresponds to one piece of position information; and matching the position information of each sub-area with a preset position information and awakening mode corresponding relation table in the awakening mode library, selecting the awakening mode corresponding to the position information of each sub-area, and configuring according to the selected awakening mode. It can be understood that the wake-up mode library further includes a table of correspondence between the preset position information and the wake-up mode, where the correspondence between the preset position information and the wake-up mode is that one position information corresponds to one wake-up mode, and the specific correspondence can be flexibly adjusted according to actual needs. As shown in table 2, table 2 is a table of a corresponding relationship between the preset location information and the wake-up mode provided in this embodiment.

TABLE 2

Presetting position information	Wake-up mode
		Common position of user	First wake-up mode (wake-up time interval of 0)
User-undefined position	Third wake-up mode (wake-up time interval 4s)
		Location not commonly used by user	Fifth wake-up mode (wake-up time interval of 8s)

For example, as shown in fig. 6, the sub-area 605 is a common unlock position of the user, the sub-area 604 is an infrequently used unlock position of the user, the sub-areas 603 and 602 are infrequently used unlock positions of the user, and as shown in table 2, the first wake-up mode is selected to configure the fingerprint identification module of the sub-area 605, the third wake-up mode is selected to configure the fingerprint identification module of the sub-area 604, and the fifth wake-up mode is selected to configure the fingerprint identification modules of the sub-areas 603 and 602.

It should be noted that, in some embodiments, when the fingerprint identification area under the screen is divided into at least two sub-areas according to the preset division rule, each sub-area has an actual usage probability, and the actual usage frequency of each sub-area may be matched with the preset actual usage frequency and wake-up pattern correspondence table in the wake-up pattern library, an wake-up pattern corresponding to the actual usage frequency is selected, and configuration is performed according to the selected wake-up pattern. The wake-up database may further include a table of correspondence between preset actual usage frequency and wake-up mode, where the correspondence between the preset actual usage frequency and the wake-up mode may be that one actual usage frequency corresponds to one wake-up mode; or one actually used frequency range segment corresponds to one awakening mode, and the specific corresponding relation can be flexibly adjusted according to actual requirements. As shown in table 3, table 3 is a table of correspondence between the preset actual usage frequency and the wake-up mode provided in this embodiment.

TABLE 3

Frequency of actual use	Wake-up mode
		Maximum frequency of use	First wake-up mode (wake-up time interval of 0)
Lowest frequency of use	Fourth wake-up mode (wake-up time interval 9s)

For example, as shown in fig. 7, the first sub-area 703 is an area with the highest probability of use in the actual use process of the user, and the second sub-area 704 is an area with the lowest probability of actual use, according to the table 3, the fingerprint identification module of the first sub-area 703 is configured with a first wake-up mode, and the fingerprint identification module of the second sub-area 704 is configured with a second wake-up mode.

And S303, performing awakening control on the fingerprint identification modules in the sub-areas according to the awakening modes configured for the sub-areas.

It should be understood that, after the fingerprint identification module in each sub-area is awakened and controlled according to the awakening mode configured for each sub-area, the fingerprint identification area under the screen includes at least two different awakening modes, and compared to the prior art in which the fingerprint identification area under the whole screen is used as a unit, the fingerprint identification area under the whole screen is always in an awakening state. Because the awakening modes corresponding to the fingerprint identification modules in the sub-regions are possibly different, when a user carries out fingerprint unlocking at present, the pressing positions of the fingerprint identification modules can intersect with the sub-regions, when a certain sub-region is in an awakening state at present and detects a part of fingerprint information, and when the current terminal is still in an un-unlocked state, the fingerprint identification modules can awaken the adjacent region of the certain sub-region quickly at the moment to obtain complete fingerprint information. That is, after performing wake-up control on the fingerprint identification modules in each sub-area according to the wake-up mode configured for each sub-area, when a certain sub-area detects partial fingerprint information, the terminal fingerprint identification fails, and there is a sub-area in which the fingerprint identification module is in a dormant state in the adjacent sub-area of the sub-area, wake-up the fingerprint identification module in the dormant state in the sub-area according to a preset wake-up policy, where the preset wake-up policy includes wake-up controlling the fingerprint identification modules in the dormant state in all the adjacent sub-areas of the sub-area, for example, as shown in fig. 8, it is assumed that 801 is a sub-area that detects

partial fingerprint information

805, and 801 includes sub-areas 802, 803, 804, and 806, where the fingerprint identification modules of

sub-areas

803 and 806 are in the dormant state, and sub-areas 802 and 804 are in the wake-area, the fingerprint identification module controlling sub-area 803 and sub-area 806 is woken up. The preset awakening strategy can also determine the target sub-area corresponding to the sub-screen fingerprint identification area of the residual fingerprint information according to the fingerprint direction of the part of the fingerprint information collected by the sub-area, and awaken the fingerprint identification module controlling the target sub-area when the fingerprint identification module of the target sub-area is in the dormant state. For example, as shown in fig. 8, it is assumed that the sub-area 801 detects partial fingerprint information 805, the fingerprint direction of the acquired partial fingerprint information 805 is the up-down direction, the target sub-area 802 corresponding to the remaining fingerprint information is determined, and when the target sub-area 802 is in the sleep state, the fingerprint identification module controlling the target sub-area 802 is awakened.

It can be understood that, at the fingerprint identification in-process, when inductive sensor detected the touch of finger, the work of infrared emitter and infrared receiver was just controlled to the controller, was waking up the fingerprint identification module according to the mode of waking up promptly when controlling, and it can only wake up the inductive sensor of fingerprint identification module.
