Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The triggering key 03 is illustratively a physical key disposed below the fingerprint recognition sensor 01. And the fingerprint identification sensor 01 and the trigger button 03 can be both arranged below the glass cover plate (not shown in fig. 1), when the button IC04 detects that the trigger button 03 receives a preset pressing operation, the button IC04 generates a trigger signal and sends the trigger signal to the processor 05, the processor 05 sends a wake-up instruction to the fingerprint identification IC02, the fingerprint identification IC02 wakes up the fingerprint identification sensor 01, and judges whether the fingerprint acquired by the fingerprint identification sensor 01 is the same as a target fingerprint stored on the fingerprint identification IC02, so as to identify the fingerprint.
The fingerprint recognition sensor 01 is normally in a sleep state due to the high power consumption of the fingerprint recognition sensor 01. When the trigger key 03 receives the preset pressing operation, the fingerprint identification sensor 01 can be awakened, but when the trigger key 03 is touched by mistake, the fingerprint identification sensor 01 can be awakened, and the energy waste is easily generated. For example, when the mobile phone is placed in a bag carried by a user, the external connection shakes and collides with other objects in the user bag, so that the fingerprint identification sensor 01 is mistakenly awakened.

The touch unit 16 and the fingerprint recognition sensor 14 are located on the same plane, and the distance between the touch unit and the fingerprint recognition sensor is smaller than a preset threshold value.
The touch unit 16 is a touch display screen or a capacitive touch sensor separately provided on the peripheral side of the fingerprint recognition sensor 14.
As a possible implementation, as shown in fig. 2B, the touch unit 16 is a touch display screen 16a of the terminal. The distance between the lower edge of the touch display screen 16a and the upper edge of the fingerprint identification sensor 14 is less than a preset threshold s.
As another possible implementation, as shown in fig. 2C, the touch unit 16 is a capacitive touch sensor 16b separately provided on the terminal. The capacitive touch sensor 16b is disposed between the fingerprint sensor 14 and the display screen 20, and a distance between a lower edge of the capacitive touch sensor 16b and an upper edge of the fingerprint sensor 14 is smaller than a preset threshold s.
Wherein the key IC12 is configured to generate a first trigger signal when the trigger key 15 is triggered, the triggering being that a physical key is pressed or a capacitive key is touched. The processor 10 is configured to send a first wake-up instruction to the touch IC13 according to the first trigger signal. The touch IC13 is configured to wake up the touch unit 16 when receiving the first wake-up command, and detect whether the touch signal collected by the touch unit 16 meets a preset condition. The processor 10 is further configured to send a second wake-up instruction to the fingerprinting IC11 if the touch signal meets a preset condition. The fingerprint IC11 is configured to wake up the fingerprint sensor 14 according to a second wake-up instruction.
In summary, in the terminal provided in this embodiment, when the trigger button is triggered, the touch unit is awakened through the touch IC, and it is detected whether the touch signal acquired by the touch unit meets the preset condition; if the touch signal meets the preset condition, awakening the fingerprint identification sensor through the fingerprint identification IC; the problem of power consumption waste caused by mistaken awakening of the fingerprint identification sensor when the trigger key is mistakenly triggered is solved; the fingerprint identification sensor can be triggered and awakened only when the finger of the user is placed at the correct position of the fingerprint identification sensor, and the effect of high power consumption cannot be caused.
Fig. 3 is a flowchart illustrating a fingerprint sensor wake-up method according to an exemplary embodiment, where the fingerprint sensor wake-up method provided by this embodiment may be applied to a terminal as shown in any one of fig. 2A to 2C, and the fingerprint sensor wake-up method may include the following steps.
In step 301, a first trigger signal sent by the key IC is received, where the first trigger signal is generated by the key IC when the trigger key is triggered.
In step 302, a first wake-up command is sent to the touch IC according to the first trigger signal.
In step 303, the touch unit is waken up by the touch IC, and it is detected whether the touch signal acquired by the touch unit meets a preset condition.
In step 304, if the touch signal meets the predetermined condition, a second wake-up command is sent to the fingerprint identification IC.
In step 305, the fingerprint sensor is awakened by the fingerprint IC.
In summary, in the fingerprint identification sensor wake-up method provided in this embodiment, when the trigger button is triggered, the touch unit is woken up by the touch IC, and it is detected whether the touch signal acquired by the touch unit meets the preset condition; if the touch signal meets the preset condition, awakening the fingerprint identification sensor through the fingerprint identification IC; the problem of power consumption waste caused by mistaken awakening of the fingerprint identification sensor when the trigger key is mistakenly triggered is solved; the fingerprint identification sensor can be triggered and awakened only when the finger of the user is placed at the correct position of the fingerprint identification sensor, and the effect of high power consumption cannot be caused.
Fig. 4 is a flowchart illustrating a fingerprint sensor wake-up method according to an exemplary embodiment, where the fingerprint sensor wake-up method provided by this embodiment may be applied to a terminal as shown in any one of fig. 2A to 2C, and the fingerprint sensor wake-up method may include the following steps.
In step 401, a first trigger signal sent by the key IC is received, where the first trigger signal is generated by the key IC when the trigger key is triggered.
When the terminal is in a dormant state, the touch unit and the fingerprint identification sensor are both in the dormant state.
Taking the example that the terminal unlocking screen needs to be subjected to fingerprint identification, when the user wakes up the terminal, the user needs to place a finger above the fingerprint identification sensor and press the finger. The fingerprint identification sensor can drive the trigger button of pressing the below. When the trigger key is pressed, the key IC generates a first trigger signal and sends the first trigger signal to the processor.
In step 402, a first wake-up command is sent to the touch IC according to a first trigger signal.
The processor sends a first wake-up instruction to the touch IC after receiving the first trigger signal.
In step 403, the touch unit is woken up by the touch IC.
After receiving the first wake-up command, the touch IC wakes up the touch unit from the sleep state to the working state.
In step 404, it is detected whether the touch signal meets the signal condition when the finger is normally placed on the fingerprint sensor through the touch IC.
And the touch unit reports the touch signal to the touch IC after acquiring the touch signal. The touch IC detects whether the touch signal meets the signal condition when the finger is normally placed on the fingerprint identification sensor.
As can be seen from fig. 5, since the distance between the touch unit and the fingerprint sensor is small, when a finger is normally placed on the fingerprint sensor, a portion of the finger beyond the fingerprint sensor generates a touch signal on the touch unit.
The signal condition met by the touch signal comprises at least one of the following three conditions:
first, the coverage area of the touch signal belongs to a preset area adjacent to the fingerprint identification sensor, that is, the touch signal generated far away from the fingerprint identification sensor in the touch unit is an abnormal signal.
Second, the coverage area of the touch signal does not exceed a preset area, which may be an empirical value of half the area of the fingertip. The touch signal with too large coverage area is an abnormal signal.
Thirdly, the signal intensity of the touch signal reaches a preset threshold. The touch signal generated during the short touch operation is an abnormal signal.
When the touch signal meets the signal condition, the touch IC feeds back a first signal to the processor, and then step 405 is performed; when the touch signal does not meet the signal condition or no touch signal is detected, the touch IC feeds back a second signal to the processor, and step 407 is entered.
In step 405, if the touch signal meets the preset condition, a second wake-up command is sent to the fingerprint identification IC.
And when the processor receives a first signal sent by the touch IC, a second awakening instruction is sent to the fingerprint identification IC.
In step 406, the fingerprint sensor is awakened by the fingerprint IC.
And after receiving the second awakening instruction, the fingerprint identification IC awakens the fingerprint identification sensor.
In step 407, if the touch signal does not meet the preset condition, the fingerprint sensor is prohibited from being woken up.
And when the processor receives the second signal sent by the touch IC, no signal is sent to the fingerprint identification IC.
In summary, in the fingerprint identification sensor wake-up method provided in this embodiment, when the trigger button is triggered, the touch unit is woken up by the touch IC, and it is detected whether the touch signal acquired by the touch unit meets the preset condition; if the touch signal meets the preset condition, awakening the fingerprint identification sensor through the fingerprint identification IC; the problem of power consumption waste caused by mistaken awakening of the fingerprint identification sensor when the trigger key is mistakenly triggered is solved; the fingerprint identification sensor can be triggered and awakened only when the finger of the user is placed at the correct position of the fingerprint identification sensor, and the effect of high power consumption cannot be caused.
