For convenience of description, the above-mentioned devices are collectively referred to as a mobile terminal. The following describes embodiments of the present invention in detail.
Referring to fig. 1A, fig. 1A is a schematic structural diagram of a mobile terminal 100 according to an embodiment of the present invention, where the mobile terminal 100 includes: an Application Processor (AP) 110, a touch display screen 120, a fingerprint recognition device 130, and a fingerprint recognition device Micro Control Unit (MCU) 150, wherein the fingerprint recognition device 130 is coupled to the touch display screen 120, the fingerprint recognition device 150 is coupled to the fingerprint recognition device 130, a fingerprint recognition area of the fingerprint recognition device 130 is located in a preset area of the touch display screen 120, wherein the AP110 is connected to the touch display screen 120 and the fingerprint recognition device 130 through a bus 160,
the touch display screen 120 is configured to execute a first operation and a second operation in parallel when detecting a touch operation of a user on the preset area, where the first operation is to notify the fingerprint identification device 130 to collect fingerprint data of the user, and the second operation is to notify the AP110 to transparentize the screen locking interface, so as to light up the entire touch display screen 120.
The touch display 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 normal wake-up state and can be used to detect a touch operation of a user.
The preset area may be any one of the preset areas of the touch display screen 120, and the preset area may be located on the left upper side (as shown in fig. 1B), the upper side, the lower side, the left side, and the right side of the touch display screen 120.
And the AP110 is used for transparentizing the screen locking interface, lightening the whole touch display screen and displaying the transparent screen locking interface on the touch display screen.
The fingerprint identification device 130 is configured to collect fingerprint data and send the fingerprint data to the fingerprint identification device MCU 150.
And the fingerprint identification device MCU150 is used for matching the fingerprint data with fingerprint template data preset in the mobile terminal and removing the transparent screen locking interface when the matching is successful.
It can be seen that, in the embodiment of the present invention, a fingerprint identification area of a fingerprint identification device of a mobile terminal is located in a preset area of a touch display screen, when a touch display screen of the mobile terminal detects a touch operation of a user on the preset area, a first operation and a second operation are executed in parallel, the first operation is to notify the fingerprint identification device to collect fingerprint data of the user, the second operation is to notify an AP to transparently lock a screen interface, light up the entire touch display screen, transparently process the lock screen interface by the AP, light up the entire touch display screen, display the transparent lock screen interface on the touch display screen, the fingerprint identification device collects fingerprint data and sends the fingerprint data to a fingerprint identification device MCU, the fingerprint identification device MCU matches the fingerprint data with fingerprint template data preset at the mobile terminal, and releases the transparent lock screen interface when the matching is successful. Therefore, the touch control display screen of the mobile terminal informs the AP of the transparent screen locking interface and lights the whole touch control display screen only when detecting the touch control operation aiming at the preset area, and simultaneously informs the fingerprint identification device to collect the fingerprint data, the non-full screen characteristic of the preset area ensures that the touch control operation aiming at the area except the preset area by a user can not simultaneously trigger the lighting of the whole screen and the notification operation, thereby avoiding the occurrence of misoperation and improving the stability of the fingerprint unlocking of the mobile terminal, in addition, the fingerprint identification device MCU can be cooperated with the AP to process the fingerprint data identification processing in the unlocking control process, avoiding the condition that the AP processes all operations with long time and low efficiency, being beneficial to improving the processing efficiency of the mobile terminal to execute the unlocking control process, in addition, due to the parallel screen lighting operation and the fingerprint data collection operation, the time consumption of the fingerprint unlocking process is shortened, the screen-off unlocking speed is favorably improved, and the accuracy and the intelligence of fingerprint unlocking of the mobile terminal are favorably improved.
In one possible example, the touch display screen 120 wakes up the AP110, the fingerprint recognition device 130, and the fingerprint recognition device MCU150 when detecting a touch operation of a user on the preset area.
The mobile terminal 100 is in a screen-off state, and the touch screen of the touch display screen 120 is in an awake state.
And the fingerprint inputting operation is a touch operation aiming at the preset area.
Wherein the preset area is smaller than the second area.
It can be seen that, in this example, when the touch display screen of the mobile terminal detects the touch operation of the user on the preset area, the AP, the fingerprint identification device and the fingerprint identification device MCU are firstly awakened, that is, the mobile terminal provides a trigger mechanism for a fingerprint unlocking initialization process (specifically, the fingerprint unlocking initialization process refers to awakening the AP, the fingerprint identification device and the fingerprint identification device MCU), and the fingerprint unlocking initialization process of the mobile terminal in the screen-off state is triggered without consuming electric power and is beneficial to improving convenience and power management efficiency of the fingerprint unlocking initialization process of the mobile terminal. In addition, due to the fact that the AP, the fingerprint identification device and the fingerprint identification device MCU are awakened to be synchronously executed, time consumption is further saved compared with a serial process, the speed of fingerprint unlocking of the mobile terminal is favorably improved, and further the accuracy and the intelligence of fingerprint unlocking of the mobile terminal are favorably improved.
In one possible example, the touch display 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 the lower side of the touch screen. The fingerprint recognition device 130 includes a fingerprint Sensor, wherein the fingerprint Sensor includes at least one of: optical fingerprint sensors, capacitive fingerprint sensors, and ultrasonic fingerprint sensors, etc.
When the fingerprint Sensor is a capacitive fingerprint Sensor and the touch screen in the touch display screen is a capacitive touch screen, the fingerprint identification device may be combined to the touch display screen in a specific representation form, for example: the fingerprint identification device is integrated into a touch screen of the touch display screen, specifically, a first sensing capacitor array of the fingerprint identification device can be embedded into a second sensing capacitor array of the touch screen, and sensing capacitors in the first sensing capacitor array are uniformly distributed in the preset area.
When the fingerprint Sensor is an optical fingerprint Sensor, the specific representation form of the fingerprint identification device combined to the touch display screen may be, for example: the fingerprint identification device is integrated into the touch control display screen, the fingerprint identification device of the mobile terminal collects user fingerprint data based on a pinhole imaging principle, the spacing layer between the touch screen and the display screen of the touch display screen is provided with a first small hole array layer in a first preset area, when the driving circuit layer of the display screen is printed, an evenly distributed small hole array is formed in a second preset area, the driving circuit layer is uniformly distributed with small hole arrays as a second small hole array layer, and the light holes in the first small hole array layer are in one-to-one correspondence with the light holes in the second small hole array layer, the optical fingerprint Sensor comprises a charge coupler CCD array layer, the CCD array layer is used for detecting light penetrating through the first small hole array layer and the second small hole array layer, and the first preset area and the second preset area correspond to the preset area.
When the fingerprint Sensor is an ultrasonic fingerprint Sensor, the specific representation form of the fingerprint identification device combined to the touch display screen may be, for example: the touch-control display screen predetermines regional below and is provided with the vacuum detection cavity, a plurality of ultrasonic sensor of evenly having arranged in the vacuum detection cavity, ultrasonic sensor include ultrasonic signal transmitter and ultrasonic signal receiver, and ultrasonic signal transmitter is used for launching specific frequency's signal and surveys user's fingerprint, and ultrasonic signal receiver is used for receiving the echo signal that reflects back. The working principle of the ultrasonic sensor is that the ultrasonic wave has the capacity of penetrating through materials, and echoes with different sizes are generated along with different materials (when the ultrasonic wave reaches the surfaces of different materials, the ultrasonic wave is absorbed, penetrated and reflected to different degrees), so that the positions of ridges and valleys of a fingerprint surface of a user can be distinguished.
The Display screen may be a Thin Film Transistor-liquid crystal Display (TFT-LCD), a Light Emitting Diode (LED) Display screen, an Organic Light-Emitting Diode (OLED) Display screen, or the like.
In one possible example, as shown in fig. 2, the mobile terminal 100 further includes a memory 140, where the memory 140 stores an Android system and a lock screen application, and the Android system includes a fingerprint Service, a Power Management Service (PMS); the AP110 and the fingerprint recognition device MCU150 are connected to the memory 140 through the bus 160.
In the aspect of lighting the entire touch display screen 120, the AP110 is specifically configured to: the AP110 calls the PMS to light up the entire touch display screen 120;
in the aspect of matching the fingerprint data with fingerprint template data preset in the mobile terminal, the fingerprint identification device MCU150 is specifically configured to: the fingerprint identification device 150 calls the FingerprintService to match the fingerprint data with fingerprint template data preset in the mobile terminal;
in the aspect of releasing the transparent lock screen interface, the fingerprint identification device MCU150 is specifically configured to: and the fingerprint identification device MCU150 calls the screen locking application to remove the transparent screen locking interface when the matching is successful.
As can be seen, in this example, since the FingerService has the authority to directly query the fingerprint template database of the Android system, when the FingerService matches the fingerprint data with the fingerprint template data, an additional authentication process is not required, which is beneficial to improving the convenience of fingerprint data comparison and improving the matching efficiency of the fingerprint data. In addition, since FingerService and PMS of the mobile terminal do not interfere with each other when performing respective operations in parallel, when other system parameters of the mobile terminal are relatively stable, fingerprint data are matched through FingerService, and the processing time t1 of the process of releasing the transparent lock screen interface through the lock screen application is relatively fixed when matching is successful, and similarly, the processing time t2 of the PMS for lighting the whole touch display screen is also relatively fixed, so that the user interface presentation result of the fingerprint unlocking process of the mobile terminal is relatively stable to a certain extent, and thus the execution stability of the fingerprint unlocking process of the mobile terminal is improved.
In one possible example, the fingerprinting device MCU150 is also used to wake up the PMS after it has been woken up.
It can be seen that, in this example, the time period during which the fingerprint identification device 130 collects the fingerprint data and the AP110 transparentizes the screen locking interface is the reference time period, the fingerprint identification device MCU150 wakes up the PMS by using the idle processing capability in the reference time period, so that the AP110 does not need to spend extra time to wake up the PMS again before lighting up the touch display screen, and the fingerprint identification device MCU150 can wait to receive the fingerprint data sent by the fingerprint identification device 130 after waking up the PMS, thereby saving the processing time of the lighting operation, being beneficial to improving the screen lighting speed, and further realizing the acceleration of unlocking in the visual effect.
In one possible example, the touch operation for the preset area is the following operations: performing touch operation on the preset area, wherein the touch time length is greater than a preset time length threshold value;
or, performing touch operation on the preset area, wherein the touch area is larger than a preset area threshold.
In this example, as the touch operation is an operation of touching the preset area and the touch duration is greater than the preset duration threshold, it can be seen that the touch operation is not a conventional touch operation such as single click, so that the user can be prevented from touching the preset area by mistake to trigger the fingerprint data acquisition operation to a certain extent,
or, since the touch operation is an operation in which the touch is performed on the preset area and the touch area is larger than the preset area threshold, it is obvious that the touch operation is not an accidental touch or other accidental operation, so that the user can be prevented from triggering the fingerprint data acquisition operation by mistakenly touching the preset area to a certain extent,
the above-mentioned two kinds of touch mode to predetermineeing the region guarantee that the user points the fingerprint face and stably contacts predetermineeing the region for fingerprint identification device can accurately gather fingerprint data, is favorable to improving the degree of accuracy of fingerprint unblock.
Referring to fig. 3, fig. 3 is a schematic flow chart of an unlocking control method according to an embodiment of the present invention, which is applied to a mobile terminal including an application processor AP, a touch display screen, a fingerprint identification device coupled to the touch display screen, and a fingerprint identification device MCU coupled to the fingerprint identification device, where a fingerprint identification area of the fingerprint identification device is located in a preset area of the touch display screen, and as shown in the drawing, the unlocking control method includes:
s301, the mobile terminal controls the touch display screen to execute a first operation and a second operation in parallel when the touch operation of the user for the preset area is detected, the first operation is used for notifying the fingerprint identification device to collect fingerprint data of the user, and the second operation is used for notifying the AP transparentization screen locking interface to light the whole touch display screen.
S302, the mobile terminal controls the AP transparent screen locking interface, lights the whole touch display screen, and displays the transparent screen locking interface on the touch display screen.
S302, the mobile terminal controls the fingerprint identification device to collect fingerprint data and sends the fingerprint data to the fingerprint identification device MCU.
S304, the mobile terminal matches the fingerprint data with fingerprint template data preset in the mobile terminal through the fingerprint identification device MCU, and releases the transparent screen locking interface when the matching is successful.
It can be seen that, in the embodiment of the present invention, a fingerprint identification area of a fingerprint identification device of a mobile terminal is located in a preset area of a touch display screen, when a touch display screen of the mobile terminal detects a touch operation of a user on the preset area, a first operation and a second operation are executed in parallel, the first operation is to notify the fingerprint identification device to collect fingerprint data of the user, the second operation is to notify an AP to transparently lock a screen interface, light up the entire touch display screen, transparently process the lock screen interface by the AP, light up the entire touch display screen, display the transparent lock screen interface on the touch display screen, the fingerprint identification device collects fingerprint data and sends the fingerprint data to a fingerprint identification device MCU, the fingerprint identification device MCU matches the fingerprint data with fingerprint template data preset at the mobile terminal, and releases the transparent lock screen interface when the matching is successful. Therefore, the touch control display screen of the mobile terminal informs the AP of the transparent screen locking interface and lights the whole touch control display screen only when detecting the touch control operation aiming at the preset area, and simultaneously informs the fingerprint identification device to collect the fingerprint data, the non-full screen characteristic of the preset area ensures that the touch control operation aiming at the area except the preset area by a user can not simultaneously trigger the lighting of the whole screen and the notification operation, thereby avoiding the occurrence of misoperation and improving the stability of the fingerprint unlocking of the mobile terminal, in addition, the fingerprint identification device MCU can be cooperated with the AP to process the fingerprint data identification processing in the unlocking control process, avoiding the condition that the AP processes all operations with long time and low efficiency, being beneficial to improving the processing efficiency of the mobile terminal to execute the unlocking control process, in addition, due to the parallel screen lighting operation and the fingerprint data collection operation, the time consumption of the fingerprint unlocking process is shortened, the screen-off unlocking speed is favorably improved, and the accuracy and the intelligence of fingerprint unlocking of the mobile terminal are favorably improved.

The mobile terminal removes the transparent screen locking interface through the fingerprint identification device MCU, including: and the mobile terminal calls the screen locking application to remove the transparent screen locking interface when the matching is successful through the fingerprint identification device MCU.
As can be seen, in this example, since the FingerService has the authority to directly query the fingerprint template database of the Android system, when the FingerService matches the fingerprint data with the fingerprint template data, an additional authentication process is not required, which is beneficial to improving the convenience of fingerprint data comparison and improving the matching efficiency of the fingerprint data. In addition, since FingerService and PMS of the mobile terminal do not interfere with each other when performing respective operations in parallel, when other system parameters of the mobile terminal are relatively stable, fingerprint data are matched through FingerService, and the processing time t1 of the process of releasing the transparent lock screen interface through the lock screen application is relatively fixed when matching is successful, and similarly, the processing time t2 of the PMS for lighting the whole touch display screen is also relatively fixed, so that the user interface presentation result of the fingerprint unlocking process of the mobile terminal is relatively stable to a certain extent, and thus the execution stability of the fingerprint unlocking process of the mobile terminal is improved.

It can be seen that, in this example, the time period during which the fingerprint identification device 130 collects the fingerprint data and the AP110 transparentizes the screen locking interface is the reference time period, the fingerprint identification device MCU150 wakes up the PMS by using the idle processing capability in the reference time period, so that the AP110 does not need to spend extra time to wake up the PMS again before lighting up the touch display screen, and the fingerprint identification device MCU150 can wait to receive the fingerprint data sent by the fingerprint identification device 130 after waking up the PMS, thereby saving the processing time of the lighting operation, being beneficial to improving the screen lighting speed, and further realizing the acceleration of unlocking in the visual effect.
In one possible example, the touch operation for the preset area is the following operations: performing touch operation on the preset area, wherein the touch time length is greater than a preset time length threshold value;
or, performing touch operation on the preset area, wherein the touch area is larger than a preset area threshold.
In this example, as the touch operation is an operation of touching the preset area and the touch duration is greater than the preset duration threshold, it can be seen that the touch operation is not a conventional touch operation such as single click, so that the user can be prevented from touching the preset area by mistake to trigger the fingerprint data acquisition operation to a certain extent,
or, since the touch operation is an operation in which the touch is performed on the preset area and the touch area is larger than the preset area threshold, it is obvious that the touch operation is not an accidental touch or other accidental operation, so that the user can be prevented from triggering the fingerprint data acquisition operation by mistakenly touching the preset area to a certain extent,
the above-mentioned two kinds of touch mode to predetermineeing the region guarantee that the user points the fingerprint face and stably contacts predetermineeing the region for fingerprint identification device can accurately gather fingerprint data, is favorable to improving the degree of accuracy of fingerprint unblock.
