The terminal has a fingerprint detection function. The fingerprint identification module can be a fingerprint identification chip, and the touch screen module can be a touch screen chip. The terminal can be a mobile phone, a tablet, a wearable electronic device and the like with the structure and the functions.
The Android system architecture is divided into four layers, an Android application layer, an Android application framework layer, an Android system operation layer and a Linux kernel layer are respectively arranged from high to low, the combination of the Android application layer, the Android application framework layer and the Android system operation layer can be called the Android layer, and the Android layer carries out information transmission with the Linux kernel layer through a Driver driving layer. When the Android system is installed on the terminal, the touch screen module corresponds to the Linux kernel layer, and the processor corresponds to the Android layer.
Fig. 1 shows a flowchart of a fingerprint detection method according to an exemplary embodiment, and the fingerprint detection method shown in fig. 1 includes the following steps:
in step 101, in response to the fingerprint detection function of the terminal being turned on, the touch screen module is controlled to continuously obtain touch position information in a fingerprint detection area on the touch screen, and after obtaining a piece of touch position information each time, it is determined whether the currently obtained touch position information meets a preset condition.
After determining that the fingerprint detection function is started, the processor can send related information to the touch screen module, the touch screen module continuously acquires touch position information in a fingerprint detection area on the touch screen based on the related information, and determines whether the currently acquired touch position information meets a preset condition after acquiring one piece of touch position information each time. The touch screen module can acquire touch position information in the fingerprint detection area at intervals according to a preset time interval.
For example, after determining that the fingerprint detection function is turned on, the processor sends a specific character such as the number 1 to the touch screen module, and after the touch screen module identifies the specific character, the processor determines that the fingerprint detection function is turned on and starts to continuously acquire the touch position information in the fingerprint detection area on the touch screen.
The processor determines whether the fingerprint detection function is turned on at various times, for example, after the processor determines that a touch operation exists on the touch screen, after the terminal is started, after a specific instruction is received, and the like.
After the touch screen module acquires touch position information every time, whether the currently acquired touch position information meets a preset condition is determined. In one embodiment, the touch position information may include coordinates of a plurality of touch positions, in which case, the touch screen module may determine a touch area based on the coordinates of the plurality of touch positions, determine whether the touch area is greater than or equal to a preset value, determine that the touch position information satisfies a preset condition if the touch area is greater than or equal to the preset value, and determine that the touch position information does not satisfy the preset condition if the touch area is less than the preset value.
In step 102, a corresponding instruction sent by the touch screen module after determining that the currently acquired touch position information meets a preset condition is received.
The corresponding instruction can indicate that the current touch operation is effective touch operation, and fingerprint identification can be further carried out. In one embodiment, the touch screen module sends a corresponding instruction to the processor after determining that the touch area is greater than or equal to the preset value.
In one embodiment, the touch screen module is provided with at least a first register and a second register, the first register is only used when the fingerprint function is started, the first register stores register values used when the fingerprint function is started, the second register is used when the fingerprint function is closed, the second register stores register values used when the fingerprint function is closed, the touch screen module directly obtains required register values from the first register when the fingerprint function is started, and directly obtains required register values from the second register when the fingerprint function is closed.
In this case, step 102 may be implemented by: and receiving a corresponding instruction which is sent by the touch screen module and carries a first register value, wherein the first register value is a register value obtained from a first register after the touch screen module determines that the touch position information meets the preset condition. And after the processor identifies the first register, the processor controls the fingerprint identification module to perform fingerprint detection. The first register value may indicate that the current touch operation is a valid touch operation, and fingerprint identification may be further performed.
After the processor determines that the fingerprint detection function is closed, the processor may control the touch screen module to obtain touch operation information on the touch screen, and obtain a second register value corresponding to the touch operation information from the second register, where the touch screen module reports the second register value to the processor, that is, the processor receives the second register value reported by the touch screen module. Through the process, the control of the terminal by the common touch operation can be realized. The touch operation information may include one or more of touch position coordinates, touch pressure, and the like.
For example, after determining that the fingerprint detection function is turned on, the processor may send a specific character, such as a number 1, to the touch screen module, and after identifying 1, the touch screen module determines that the fingerprint detection function is turned on, and starts to continuously acquire touch position information in a fingerprint detection area on the touch screen, and if the touch position information meets a preset condition, acquires a first register value from a first register, and reports the first register value to the processor.
The processor can send another specific character such as a number 2 to the touch screen module after determining that the fingerprint detection function is closed, and the touch screen module identifies 2 and then determines that the fingerprint detection function is closed, acquires touch operation information on the touch screen, acquires a second register value corresponding to the touch operation information from the second register, and reports the second register value to the processor.
If only one register is installed on the touch screen module, when the use state of the fingerprint detection function is switched, the register value in the register needs to be converted, and the register value used in the switched use state is obtained. Compared with the mode that only one register is installed on the touch screen module, the plurality of registers are installed on the touch screen module, the operation of changing the register value in the register when the using state of the fingerprint detection function is switched is omitted, the data processing amount is reduced, the touch screen module can rapidly acquire the required register value from the specific register, the fingerprint detection efficiency is improved, and the power consumption of the terminal is reduced.
When only one register is installed on the touch screen module, and the touch screen module uses the method in the related technology to continuously report the touch position information to the processor, the reported touch position information is located in the message queue, when the fingerprint is switched to the use state of the function, the touch screen module is easy to have the situation of misreading the data in the message queue based on the setting of the system layer, so that the fingerprint unlocking failure, the reading interrupt signal delay and the like are caused, and the interrupt signal can be understood as the touch position information which meets the preset condition and is reported by the touch screen module.
When the plurality of registers are installed on the touch screen module and the touch screen module acquires the first register value from the first register and reports the first register value to the processor after determining that the currently acquired touch position information meets the preset condition, the occurrence of misreading of data in the message queue by the touch screen module in the scheme is avoided, and the accuracy and the efficiency of fingerprint unlocking are improved.
The touch screen module can send the touch position information meeting the preset condition to the processor together for the processor to use.
In step 103, the fingerprint identification module is controlled to perform fingerprint identification based on the corresponding instruction.
And after the processor receives the corresponding instruction, the fingerprint identification module is controlled to identify the acquired fingerprint information. Specifically, the collected fingerprint information may be matched with fingerprint information entered in advance, and if the matching is passed, it is determined that the fingerprint detection is passed, and if the matching is not passed, it is determined that the fingerprint detection is not passed.
In one embodiment, the corresponding instruction carries a first register value, and the processor controls the fingerprint identification module to identify the collected fingerprint information after identifying the first register value.
In one embodiment, the terminal further has a screen turning display function, and the screen turning display function is that after the terminal is locked, under the condition that the screen is not lightened, the screen always displays information such as time, date, electric quantity and the like.
After the terminal is in the lock screen state and the fingerprint detection function is started, information displayed on the information screen is displayed in the fingerprint detection area. For example, an icon displayed on a message screen may be displayed within the fingerprint detection area.
In the realization, be in lock screen state and fingerprint detection function at the terminal and open the back, the user can remove the position of the information of message screen display, can remove the information of message screen display and show to the fingerprint detection region in, at this moment the treater removes to the fingerprint detection region in based on user's operation orbit information of message screen display, later closes the facula display in the fingerprint detection region to the information display of message screen display is in the fingerprint detection region.
For example, the screen displays a clock icon when the user turns on the screen, and after the terminal receives the operation that the user moves the clock icon into the fingerprint detection area, the terminal closes the light spot display in the fingerprint detection area and displays the clock icon in the fingerprint detection area.
Compare in the information that shows the facula and the display of message screen in different screen areas, the user can remove the position of the information that the display of message screen shows in this embodiment, the facula that the treater is through closing in the fingerprint detection area shows, and the information display that will show the display of message screen shows is in the fingerprint detection area, the display area has been reduced, the terminal consumption is further reduced, the user has the self-defined authority of information display position when showing the display of message screen simultaneously, user's use experience has been improved, the information that shows the display of message screen has the function that suggests the fingerprint detection area in addition, be convenient for the user through looking over the information that the display of message screen shows, know the position in fingerprint detection area.
According to the terminal, after the fingerprint detection function is determined to be started, the touch screen module is controlled to continuously acquire the touch position information in the fingerprint detection area on the touch screen, and after the touch position information is acquired every time, whether the currently acquired touch position information meets the preset condition is determined, the touch screen module sends the corresponding instruction to the processor after the currently acquired touch position information meets the preset condition is determined, the processor controls the fingerprint identification module to perform fingerprint identification based on the corresponding instruction, fingerprint detection is achieved, and therefore the operation that the touch screen module continuously reports the touch position information to the processor in the related technology is omitted, the power consumption of the touch screen module is reduced, and the power consumption of the terminal is reduced.
