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.

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.
