Wherein, the touch screen 120 includes a touch screen and a display screen, the touch screen includes a touch screen MCU, and the touch screen MCU is in a state of always awake, and can be used to detect a user's touch operation.

Wherein, the first area may be any preset area of the touch screen 120, and the preset area may be located on the upper left side (as shown in FIG. 1B ), the upper side, the lower side, or the left side of the touch screen 120.

The AP110 is also used to release the lock screen interface.

It can be seen that in the embodiment of the present invention, the fingerprint identification area of the fingerprint identification device of the mobile terminal is located in the first area of the touch display screen, and the touch display screen of the mobile terminal detects the user's first touch on the first area. During operation, the first operation and the second operation are executed in parallel. The first operation is to notify the fingerprint identification device to collect the user's fingerprint data, and the second operation is to notify the AP to light up the entire touch screen, and the AP lights up the entire touch screen.

It can be seen that only when the touch screen of the mobile terminal detects the first touch operation on the first area, it notifies the AP to light up the entire touch screen, and at the same time notifies the fingerprint identification device to collect fingerprint data. The feature makes the user's touch operation on the area other than the first area not trigger the operation of lighting up the whole screen and the notification operation at the same time, which can avoid the occurrence of misoperation and improve the stability of fingerprint unlocking of mobile terminals. In addition, fingerprint The MCU of the identification device can cooperate with the AP to process the fingerprint data identification process in the unlocking control process, avoiding the time-consuming and inefficient situation of AP processing all operations, which is conducive to improving the processing efficiency of the mobile terminal in the unlocking control process. In addition, due to the parallel bright screen operation And the fingerprint data collection operation shortens the time-consuming process of fingerprint unlocking, helps to improve the speed of unlocking when the screen is off, and further helps to improve the accuracy and intelligence of mobile terminal fingerprint unlocking.

In a possible example, the touch display screen 120 is further configured to simultaneously wake up the AP 110 , the fingerprint recognition device 130 and the fingerprint The identification device MCU150, the indicator light 160 is located in the first area, and the second area is an area of the touch display screen 120 other than the first area; wherein, the mobile terminal 100 is off screen state, the touch screen of the touch display screen 120 is in a wake-up state.

The fingerprint identification device MCU 150 is used to light the indicator light 160 located in the first area of the touch display screen 120 , and the lighted indicator light 160 is used to guide the user to perform a fingerprint entry operation.

Wherein, the fingerprint entry operation is a first touch operation on the first area.

Wherein, the first area is smaller than the second area.

Wherein, the indicator light may be arranged below the first area of the touch display screen, and the indicator light may be, for example, an LED.

It can be seen that in this example, when the touch screen of the mobile terminal detects the user's second touch operation on the second area, it first wakes up the AP, the fingerprint recognition device, and the fingerprint recognition device MCU, and notifies The MCU of the fingerprint identification device lights up the indicator light, and the indicator light is located in the first area; secondly, the MCU of the fingerprint identification device lights up the indicator light, and the indicator light is used to promptly remind the user of the location of the fingerprint identification device for fingerprinting. data entry, and since the second area is an area other than the first area in the touch screen, that is to say, the mobile terminal provides a fingerprint unlocking initialization process (the fingerprint unlocking initialization process specifically refers to waking up the AP, fingerprint identification device and the fingerprint identification device MCU, and by lighting the indicator light located in the first area), the AP, the fingerprint identification device and the fingerprint identification device MCU are continuously woken up without power consumption in the off-screen state, and because the first area is smaller than the second area, the user can conveniently touch the second area, thereby triggering the fingerprint unlocking initialization process of the mobile terminal in the off-screen state, which is conducive to improving the convenience and power management efficiency of the fingerprint unlocking initialization process of the mobile terminal.

In addition, since the operations of waking up the AP, the fingerprint recognition device and the MCU of the fingerprint recognition device are performed synchronously, it saves time compared to the serial process, which is beneficial to further improve the speed of fingerprint unlocking of the mobile terminal. In addition, when the fingerprint matching is successful, the Lighting the indicator light located in the first area instead of partially lighting the first area of the touch screen avoids excessive consumption of the luminescent material of the touch screen in the first area, improves the balance of the touch screen, and prolongs the life of the touch screen. The service life of the touch display screen, in turn, is conducive to improving the accuracy and intelligence of fingerprint unlocking of mobile terminals.

In a possible example, the touch screen 120 includes a touch screen and a display screen, the touch screen and the display screen are stacked, and the display screen is disposed on a lower side of the touch screen. The fingerprint identification device 130 includes a fingerprint sensor, wherein the fingerprint sensor includes at least one of the following: an optical fingerprint sensor, a capacitive fingerprint sensor, and an ultrasonic fingerprint sensor.

When the fingerprint sensor is a capacitive fingerprint sensor and the touch screen in the touch screen is capacitive, the specific form of combining the fingerprint identification device with the touch screen can be, for example: the fingerprint The identification device is integrated into the touch screen of the touch screen, specifically, the first inductive capacitor array of the fingerprint identification device can be embedded in the second inductive capacitor array of the touch screen, and the first The sensing capacitors in a sensing capacitor array are uniformly distributed in the first area.

When the fingerprint sensor is an optical fingerprint sensor, the specific form of combining the fingerprint identification device with the touch display screen may be, for example: the fingerprint identification device is integrated into the touch display screen, and the mobile terminal The fingerprint identification device collects user fingerprint data based on the principle of pinhole imaging, and the spacer layer between the touch screen and the display screen of the touch display screen is provided with a first pinhole array layer in a first preset area, and the The driving circuit layer of the display screen forms a uniformly distributed small hole array in the second predetermined area during printing, and the uniformly distributed small hole array on the driving circuit layer serves as the second small hole array layer, and the first small hole array The light transmission holes in the layer correspond to the light transmission holes in the second small hole array layer, and the optical fingerprint Sensor includes a charge-coupled device CCD array layer, and the CCD array layer is used to detect light passing through the first small hole array layer. For the light in the hole array layer and the second small hole array layer, the first preset area and the second preset area both correspond to the first area.

The working principle of the ultrasonic sensor is to use the ability of ultrasonic waves to penetrate materials, and produce echoes of different sizes with different materials (when ultrasonic waves reach the surface of different materials, they are absorbed, penetrated and reflected in different degrees), and can distinguish user fingerprints The location of the ridges and valleys of the surface.

The display screen may be a thin film transistor liquid crystal display (Thin Film Transistor-Liquid Crystal Display, TFT-LCD), a light emitting diode (Light Emitting Diode, LED) display screen, an organic light emitting diode (Organic Light-Emitting Diode, OLED) display screen, etc. .

In a possible example, as shown in FIG. 2, the mobile terminal 100 further includes a memory 140, the memory 140 stores an Android system, and the Android system includes a fingerprint service FingerprintService, a power management service (Power Management Service, PMS); wherein, the AP110 and the fingerprint identification device MCU150 are connected to the memory 140 through the bus 170 .

In terms of matching the fingerprint data with the fingerprint template data preset in the mobile terminal, the fingerprint recognition device MCU150 is specifically used for: the fingerprint recognition device MCU150 invokes the FingerprintService to convert the fingerprint data Matching with the fingerprint template data preset in the mobile terminal.

In this possible example, the AP 110 is also used to wake up the PMS before turning on the entire touch screen 120 .

It can be seen that in this example, since the AP of the mobile terminal wakes up the PMS before lighting the touch display screen, due to the early wake-up, the subsequent lighting operation can light the entire touch display screen through the PMS without waking up the PMS again, thus The operation time required to wake up the PMS is saved. It is beneficial to improve the speed for the user to unlock the fingerprint on the bright screen.

In a possible example, when the touch screen 120 detects the user's first touch operation on the first area, it notifies the fingerprint identification device MCU 150 to turn off the indicator light 160; the mobile terminal The indicator light 160 is turned off by the fingerprint identification device MCU 150 .

Therefore, the touch screen can notify the MCU of the fingerprint identification device to turn off the indicator light, and the mobile terminal can turn off the indicator light through the MCU of the fingerprint identification device.

In a possible example, the second touch operation on the second area is the following operation: performing N consecutive touch operations on the second area within a preset duration range, where N is greater than 1 an integer; or, performing touch sliding on the second area, and the distance of the touch sliding is greater than the preset distance threshold; or, performing touch sliding on the second area, and the touch sliding graphic matches the preset graphic operation; or, perform an operation of pressing on the second area with a pressing force greater than a preset force threshold.

It can be seen that the first 2. The touch operation is not a conventional touch operation such as a single click, so that to a certain extent, the unnecessary power consumption of the mobile terminal caused by the frequent touch of the touch screen by the user to wake up the AP, the fingerprint recognition device and the fingerprint recognition device MCU can be avoided. , which is beneficial to reduce power consumption and improve the power usage efficiency of the mobile terminal.

In a possible example, the first touch operation on the first area is the following operation: touch on the first area and the touch duration is longer than a preset duration threshold.

It can be seen that in this example, since the first touch operation is an operation of touching the first area and the touch duration is longer than the preset duration threshold, it can be seen that the first touch operation is not a conventional touch operation such as a single click In this way, to a certain extent, it is possible to prevent the user from accidentally touching the first area to trigger the fingerprint data collection operation, and ensure that the fingerprint surface of the user's finger touches the first area stably, so that the fingerprint identification device can accurately collect fingerprint data, which is conducive to improving the accuracy of fingerprint unlocking.

It can be seen that only when the touch screen of the mobile terminal detects the first touch operation on the first area, it notifies the AP to light up the entire touch screen, and at the same time notifies the fingerprint identification device to collect fingerprint data. The feature makes the user's touch operation on the area other than the first area not trigger the operation of lighting up the whole screen and the notification operation at the same time, which can avoid the occurrence of misoperation and improve the stability of fingerprint unlocking of mobile terminals. In addition, fingerprint The MCU of the identification device can cooperate with the AP to process the fingerprint data identification process in the unlocking control process, avoiding the time-consuming and inefficient situation of AP processing all operations, which is conducive to improving the processing efficiency of the mobile terminal in the unlocking control process. In addition, due to the parallel bright screen operation And the fingerprint data collection operation shortens the time-consuming process of fingerprint unlocking, helps to improve the speed of unlocking when the screen is off, and further helps to improve the accuracy and intelligence of mobile terminal fingerprint unlocking.
