Please refer to FIG. 1A. FIG. 1A is a schematic structural diagram of a mobile terminal provided by an embodiment of the present application. The mobile terminal includes a processor 10, a memory 20, a signal processor 30, a communication interface 40, a touch screen 50, a speaker 60, A microphone 70, a random access memory (Random Access Memory, RAM) 80, a camera 90, a sensor 100, and the like.

The touch screen 50 includes a display screen and a touch panel (Touch Panel, TP), and the touch screen 50 includes a fingerprint collection area. The fingerprint collection area is an area in the touch screen, that is, a large area that can be pressed by multiple fingers at the same time, rather than a small area that can only be pressed by a single finger. The location where the fingerprint collection area is located may be the middle area of the touch screen, the upper part of the touch screen, the lower part of the touch screen, etc., which is not limited here.

The sensor 100 includes an under-screen fingerprint sensor, an infrared sensor, a gyroscope, and the like. The under-screen fingerprint sensor is arranged below the fingerprint collection area (as shown in Figure 1B). The under-screen fingerprint sensor can collect signals in the fingerprint collection area. The under-screen fingerprint sensor can be an optical under-screen fingerprint sensor, or a The capacitive under-screen fingerprint sensor may also be an ultrasonic under-screen fingerprint sensor, which is not limited here. When the under-screen fingerprint sensor is an optical under-screen fingerprint sensor, the signal collected by the under-screen fingerprint sensor is an optical signal.

Among them, the principle of fingerprint collection under the regional screen can be to use the light emitted by the fingerprint collection area to illuminate the finger placed on the fingerprint collection area. When the light emitted by the fingerprint collection area reaches the finger, it will be reflected, and the under-screen screen set below the fingerprint collection area will be reflected. The lower fingerprint sensor receives the reflected light signal. Due to the uneven texture of the fingerprint, the light absorption amplitude is different, so that the fingerprint image with different brightness and darkness can be obtained. Alternatively, the light signal transmitted through the finger is received by the sensor, so as to obtain fingerprint images with different brightness and darkness. The principle of fingerprint collection under the screen in the specific area is not limited here.

Among them, the TP includes two interrupt pins, one interrupt pin is connected to the processor 10, and the other interrupt pin is connected to the under-screen fingerprint sensor. The schematic diagram of the structure of the processor is shown in FIG. 1C , and the schematic diagram of the structure of the fingerprint sensor under the screen is shown in FIG. 1D . Among them, ground pin (Ground, GND), power supply voltage pin (Voltage Drain Drain, VDD), reset pin (RESET, RST), interrupt pin (Interrupt, INT), empty pin (NOT CONNECTED, NC ), system clock pin (System Clock, SCLK), SPI bus master input/slave output pin (SPI Bus Master Input/SlaveOutput, MISO), SPI bus master output/slave input pin (SPI Bus Master Output/Slave Input, MOSI), chip select signal pin (Chip Select, CS), TP interrupt pin (TP_INT), Serial Peripheral Interface (Serial Peripheral Interface, SPI), S, G, D in Figure 1D are the three MOS transistors pins. It can be seen from Figure 1C and Figure 1D that the processor and the fingerprint sensor under the screen each have a TP-INT, which is used to connect the interrupt pin of the TP.

In this embodiment of the present application, the TP is configured to send a first interrupt request to the under-screen fingerprint sensor and a second interrupt request to the processor when an event to be unlocked is detected, and the touch screen removes the The area outside the fingerprint collection area is in the off-screen state;

The off-screen fingerprint sensor is used to perform a fingerprint collection operation after receiving the first interrupt request, and to send the collected first fingerprint image to the processor 10 for a fingerprint identification operation;

The processor 10 is configured to, after receiving the second interrupt request, perform a screen wake-up operation, where the screen wake-up operation includes a delayed execution process, and the delayed execution process is used to extend the time period required for the screen wake-up operation to causing the screen wake-up operation to be completed after the fingerprint identification operation is completed;

The processor 10 is configured to perform an unlocking operation when the fingerprint recognition is successful, and control the touch screen to display a main interface after the unlocking operation is completed and the screen wake-up operation is completed.

It should be noted that the terms "first", "second", "third" and "fourth" in the description and claims of the present application and the drawings are used to distinguish different objects, rather than Used to describe a specific order. Furthermore, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

In the above-mentioned embodiment, the screen wake-up operation may further include a multimedia display processor power-on process, a screen initialization process, a frame refresh process, and a screen backlight lighting process, and the delayed execution process precedes the screen backlight lighting process.

In the above embodiment, the duration required for the delayed execution process is determined based on a preset formula, and the preset formula is: T=[(T1+T2)-T3+I], where T is the delayed execution The duration required for the process, the T1 is the duration required for the fingerprint collection operation of the last fingerprint unlocking, the T2 is the duration required for the fingerprint recognition operation of the last fingerprint unlocking, and T3 is the last fingerprint unlocking The screen wake-up operation The required duration, the I is a preset threshold.

In the above embodiment, the processor 10 is further configured to control the touch screen to display a lock screen interface after the fingerprint recognition fails and the screen wake-up operation is completed, and to control the fingerprint collection area to display prompt information, the The prompt information is used to prompt to re-enter the fingerprint.

In the above-mentioned embodiment, after controlling the touch screen to display the main interface, the processor 10 is further configured to hide the software installed in the mobile terminal when it is determined that the user corresponding to the first fingerprint image is not a preset user The icon of at least one preset application.

The processor 10 is further configured to control the fingerprint collection area to display the icon of the at least one preset application when the fingerprint identification is successful and it is determined that the user corresponding to the second fingerprint image is a preset user.

In the above-mentioned embodiment, after controlling the fingerprint collection area to display the icon of the at least one preset application, the processor 10 is further configured to, after detecting an error for an area of the touch screen other than the fingerprint collection area, During the second touch operation, the icon of the at least one preset application is removed and displayed from the fingerprint collection area.

It should be noted that, for the specific implementation process of the steps executed by each module, reference may be made to the specific implementation process described in the following method, which will not be described here.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a fingerprint unlocking method provided by an embodiment of the present application, which is applied to the above-mentioned mobile terminal. The method includes:

Step 201: When detecting an event to be unlocked, the TP sends a first interrupt request to the fingerprint sensor under the screen, and sends a second interrupt request to the processor, and the display of the touch screen area other than the fingerprint collection area is turned off. screen status.

Wherein, the to-be-unlocked event is, for example, a screen unlocking event, and the to-be-unlocked event is triggered when the mobile terminal detects a third touch operation on the fingerprint collection area, and the third touch operation may be a click operation or a The pressing operation may also be a sliding operation, which is not limited here.

In the above embodiment, before the event to be unlocked is detected, the method further includes: the processor lights the fingerprint collection area to a first brightness;

After receiving the second interrupt request, the processor adjusts the brightness of the fingerprint collection area to a second brightness, where the second brightness is greater than the first brightness.

The first brightness may be the display brightness of the touch screen currently set by the mobile terminal, or may be a preset brightness, which is not limited herein.

Specifically, the second brightness is a preset brightness; or the second brightness is determined by the mobile terminal according to the ambient light brightness of the environment where the mobile terminal is currently located, such as determined according to the mapping relationship between the ambient light brightness and the brightness of the fingerprint collection area. The second brightness corresponding to the ambient light brightness; or the second brightness is determined by the mobile terminal according to the current geographic location of the mobile terminal, such as determining the second brightness corresponding to the current geographic location according to the mapping relationship between the geographic location and the brightness of the fingerprint collection area; and many more.

It can be seen that, in the embodiment of the present application, the fingerprint collection area is first lit to a lower brightness, and when the fingerprint collection area is touched, the brightness of the second area is increased, compared with the entire fingerprint collection area. The brightness is improved, and the present application only improves the brightness of the second area, which reduces power consumption. In addition, the fingerprint collection operation is performed only after the brightness of the second area is increased, which improves the quality of the collected fingerprint image.

In the above-mentioned embodiment, before the event to be unlocked is detected, the touch screen is in a screen-off state, and the method further includes:

After receiving the second interrupt request, the processor lights the fingerprint collection area to a third brightness.

The third brightness is a relatively bright brightness, which may be the same as or different from the above-mentioned second brightness, which is not limited herein.

It can be seen that, in the embodiment of the present application, the fingerprint collection area is lit only when the fingerprint collection area is touched, realizing the unlocking of the black screen, and only the fingerprint collection area is lit, which reduces power consumption.

Step 202: After receiving the first interrupt request, the under-screen fingerprint sensor performs a fingerprint collection operation, and sends the collected first fingerprint image to the processor for a fingerprint recognition operation.

Wherein, when the under-screen fingerprint sensor is an under-screen optical fingerprint sensor, the specific implementation manner of the under-screen fingerprint sensor performing the fingerprint collection operation is as follows: the under-screen fingerprint sensor collects optical signals, obtains an image, and performs image processing on the image to obtain an image. Obtain the first fingerprint image in the image.

Step 203: After receiving the second interrupt request, the processor performs a screen wake-up operation, and the screen wake-up operation includes a delayed execution process, and the delayed execution process is used to extend the time required for the screen wake-up operation to The screen wake-up operation is completed after the fingerprint identification operation is completed.

Step 204: When the fingerprint recognition is successful, the processor performs an unlocking operation, and after the unlocking operation is completed and the screen wake-up operation is completed, the processor controls the touch screen to display a main interface.

Specifically, the current process of fingerprint unlocking under the screen is usually as follows: when the TP detects a screen unlocking event, the TP sends an interrupt request to the processor; after the processor receives the interrupt request, the processor executes the screen wake-up operation, and at the same time the processor Send an interrupt request to the under-screen fingerprint sensor; after receiving the interrupt request, the under-screen fingerprint sensor performs a fingerprint collection operation, and then sends the collected fingerprint image to the processor, and the processor performs a fingerprint identification operation. Since the time required for the screen wake-up operation is originally shorter than the time required for fingerprint collection + fingerprint recognition + fingerprint unlocking, the start time of fingerprint collection in the prior art is earlier than the start time of screen wake-up, thus making the fingerprint unlocking complete. There is a sufficient time difference between the moment and the moment when the screen wakes up, and there is no screen splash problem.

In this application, since the TP has two pins, when the TP detects an event to be unlocked, the TP will send an interrupt request to the fingerprint sensor and the processor under the screen at the same time, so that the start time of the fingerprint collection is the same as the screen wake-up time. The starting time is almost the same, which shortens the time difference between the time when the fingerprint is unlocked and the time when the screen wakes up, causing the screen to flicker.

In this case, a delayed execution process is added to the screen wake-up operation to extend the time required for the screen wake-up operation, so that the screen wake-up operation is completed after the fingerprint recognition operation is completed, avoiding the increase of the unlocking speed. Splash screen problem. At the same time, because an additional interrupt pin connected to the fingerprint sensor under the screen is added on the TP, when it is detected that the finger touches the fingerprint collection area, the TP directly informs the fingerprint sensor under the screen to perform the fingerprint collection operation, which improves the unlocking speed.

In the above embodiment, the screen wake-up operation further includes a multimedia display processor power-on process, a screen initialization process, a frame refresh process, and a screen backlight lighting process, and the delayed execution process precedes the screen backlight lighting process.

Specifically, the current flow of the screen wake-up operation is usually: first perform the power-on process, after the power-on process is completed, perform the screen initialization process, after the screen initialization process is completed, perform the frame refresh process After the frame refresh process is completed, execute the The process of lighting the screen backlight, after the process of lighting the screen backlight is completed, the touch screen is lit.

In the embodiment of the present application, a delay execution process is additionally added to the existing screen wake-up operation process, and the delayed execution process is before the screen backlighting process, for example, the delayed execution process is in the frame brushing process and the screen lighting process. Between the backlight process, or between the screen initialization process and the frame refresh process, or between the power-on process and the screen initialization process, etc.

In the above embodiment, the duration required for the delayed execution process is determined based on a preset formula, and the preset formula is: T=[(T1+T2)-T3+I], where T is the delayed execution The duration required for the process, the T1 is the duration required for the fingerprint collection operation of the last fingerprint unlocking, the T2 is the duration required for the fingerprint recognition operation of the last fingerprint unlocking, and T3 is the last fingerprint unlocking The screen wake-up operation The required duration, the I is a preset threshold.

The preset threshold is, for example, 0, 5ms, 10ms, 18ms, 40ms, 50ms or other values.

Among them, the last time refers to the time closest to the current system time. For example, the last fingerprint unlock refers to the fingerprint unlock closest to the current system time. For example, the mobile terminal records the unlock time of 3 fingerprint unlocks. Fingerprint unlock 1 corresponds to unlock time 1, fingerprint unlock 2 corresponds to unlock time 2, and fingerprint unlock corresponds to unlock time 2. 3 corresponds to unlock time 3, and unlock time 3 is the closest to the current system time, so the last fingerprint unlock is fingerprint unlock 3.

For example, assuming that T1=100ms, T2=265ms, T3=260ms, and I=10ms, the time required to delay the execution process is equal to (100ms+265ms)-(260ms)+(10ms)=115ms.

In the above-mentioned embodiment, the duration required for the delayed execution process is preset, and the preset value is obtained by the inspector based on the inspection data.

In the above embodiment, the method further includes:

After the fingerprint recognition fails and the screen wake-up operation is completed, the processor controls the touch screen to display a lock screen interface, and controls the fingerprint collection area to display prompt information, where the prompt information is used to prompt to re-enter the fingerprint .

It can be seen that, in this embodiment of the present application, the fingerprint collection area is used to display prompt information, which improves the usage rate of the fingerprint collection area.

In the above embodiment, after the processor controls the touch screen to display the main interface, the method further includes:

When it is determined that the user corresponding to the first fingerprint image is not a preset user, the processor hides an icon of at least one preset application installed in the mobile terminal.

The preset user is a pre-set user with a relatively high priority, for example, the owner of the mobile terminal or the like. The security priority of the preset application is greater than or equal to the preset priority, and/or the usage frequency of the preset application is greater than or equal to the preset frequency, and the preset application includes Alipay, WeChat, QQ, Contacts, Taobao, etc.

It can be seen that, in the embodiment of the present application, the icon of at least one preset application is hidden when it is not the preset user to unlock and enter the main interface, so as to avoid the problem of information leakage.

Further, after the processor hides the icon of at least one preset application installed in the mobile terminal, the method further includes:

When detecting a first touch operation on the fingerprint collection area, the TP sends a third interrupt request to the under-screen fingerprint sensor;

After receiving the third interrupt request, the off-screen fingerprint sensor performs a fingerprint collection operation, and sends the collected second fingerprint image to the processor for a fingerprint identification operation;

When the fingerprint identification is successful and it is determined that the user corresponding to the second fingerprint image is a preset user, the processor controls the fingerprint collection area to display an icon of the at least one preset application.

The first touch operation may be a click operation, a pressing operation, or a sliding operation, which is not limited herein.

It should be noted that, in this embodiment, the processor controls the fingerprint collection area to display the icon of the at least one preset application only to perform an icon display operation, rather than performing an unhiding operation.

It can be seen that in the embodiment of the present application, after hiding the icon of at least one preset application, the preset user can trigger the display of the icon of the at least one preset application through the fingerprint collection area, which improves the display of the hidden application. Convenience of icons.

Further, after the processor controls the fingerprint collection area to display the icon of the at least one preset application, the method further includes:

The second touch operation may be a click operation, a pressing operation, or a sliding operation, which is not limited herein.

It should be noted that, in this embodiment, after the processor removes and displays the icon of the at least one preset application from the fingerprint collection area, the icon of the at least one preset application is still in a hidden state.

It can be seen that, in the embodiment of the present application, after the hidden application icon is displayed, the user can touch an area other than the fingerprint collection area to trigger the removal and display of the icon of the at least one preset application, which improves the mobile phone usage. In addition to the convenience of showing hidden application icons.

Further, after the processor controls the fingerprint collection area to display the icon of the at least one preset application, the method further includes:

When detecting a fourth touch operation on one of the icons of the at least one preset application, the processor unhides the one of the icons.

The fourth touch operation includes at least one of the following: an operation of dragging one of the icons out of the fingerprint collection area; an operation of long pressing one of the icons; dragging the one of the icons on the fingerprint The operation of sliding the collection area, and the sliding track is the preset track.

It should be noted that, in this embodiment, after the processor unhides the one of the icons, the one of the icons is no longer in the hidden state, and the user can find the one of the icons through the main interface.

It can be seen that, in the embodiment of the present application, after the hidden application icons are displayed, if the user performs a specific touch operation on one of the icons, it will trigger to unhide the one of the icons. the convenience of the app icon.

In the above embodiment, after the processor controls the touch screen to display the main interface, the method further includes:

When it is determined that the user corresponding to the first fingerprint image is the preset user, the processor controls the fingerprint collection area to display an icon of the at least one preset application.

It can be seen that, in the embodiment of the present application, the icon of at least one preset application is displayed only when the preset user unlocks and enters the main interface, which avoids the problem of information leakage. In addition, since the unlocking operation is performed by touching the fingerprint collection area, the icon of the at least one preset application is displayed through the fingerprint collection area, and there is no need for the user to search for the icon of the at least one application in the main interface, and the activation of the at least one application is improved. efficiency.

Further, after the processor controls the fingerprint collection area to display the icon of the at least one preset application, the method further includes:

When detecting a fifth touch operation on the area of the touch screen other than the fingerprint collection area, the processor moves the icon of the at least one preset application from the fingerprint collection area to the area other than the fingerprint collection area. The area outside the fingerprint collection area is displayed.

The fifth touch operation may be a click operation, a pressing operation, or a sliding operation, which is not limited herein.

It should be noted that, in this embodiment, since the icon of the at least one preset application is not hidden before the icon of the at least one preset application is displayed in the fingerprint collection area, it is During the fifth touch operation in the area other than the fingerprint collection area, the processor directly moves the icon of the at least one preset application from the fingerprint collection area to the area other than the fingerprint collection area for display.
