Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Before explaining the embodiments of the present disclosure in detail, an application scenario related to the embodiments of the present disclosure will be described.
Fingerprint detection technology has been widely applied to the display screen unlocking and application unlocking processes of mobile terminals, wherein the in-screen fingerprint detection based on a touch display screen is a trend. The fingerprint detection in the screen is to arrange a fingerprint detection chip at the lower layer of a touch display screen of the mobile terminal, and a user can realize the fingerprint detection through the related area of the touch display screen.
The following description will be given of an example in which the fingerprint detection scheme provided by the present disclosure is applied to a display screen supporting intra-screen fingerprint detection. Referring to fig. 1, which shows a schematic diagram of a display screen of a mobile terminal supporting intra-screen fingerprint detection, the display screen 100 of the mobile terminal at least includes a touch display assembly 102, a fingerprint chip 104, a pressure sensor 106, a connection portion 108, a fingerprint Flexible Circuit board (FPC) 110 and an adhesive portion 112. Among other things, the touch display assembly 102 may include: the display panel comprises a protective glass plate, a touch component and a display panel (the display panel can be an Active-matrix Organic Light Emitting Diode (AMOLED) display panel), wherein the protective glass plate is used for protecting the display screen, the touch component is used for detecting touch operation acting on the display screen, and the display panel is used for displaying on a screen; the fingerprint chip 104 is used for fingerprint detection; the pressure sensor 106 is used for detecting touch pressure generated by touch operation; the connection portion 108 is used to connect the pressure sensor 106 and the fingerprint FPC 110; the fingerprint FPC110 is used to electrically connect the fingerprint chip 104 with the control component.
Referring to fig. 2, a flowchart of a fingerprint detection method provided in an embodiment of the present disclosure is shown, and this embodiment takes the fingerprint detection method as an example for being used in the display screen 100 of the mobile terminal shown in fig. 1. The method comprises the following steps:
in step S201, a touch operation acting on the display screen of the mobile terminal is detected.
In an alternative implementation, the touch operation is detected by a touch sensor, such as the aforementioned touch component.
In step S202, when the touch operation is applied to the fingerprint detection area of the display screen, if the pressure sensor cannot acquire the pressure value, the fingerprint chip is controlled to perform the fingerprint detection operation.
The pressure sensor is used for detecting touch pressure of touch operation, and the magnitude of the touch pressure can be represented by a pressure value.
Alternatively, the pressure value may represent a numerical value of a touch pressure generated by a touch operation acquired by the pressure sensor, or may be a parameter representing a magnitude of the touch pressure, such as a pressure level parameter.
This touch operation that the detection acted on mobile terminal's display screen, when touch operation acted on the fingerprint detection region of display screen, if can't acquire the pressure value through pressure sensor, directly carry out the fingerprint detection operation for the fingerprint detection function still can be used when pressure sensor goes wrong, thereby has increased the fault-tolerant ability of fingerprint detection flow to pressure sensor.
Referring to fig. 3, which shows a flowchart of a fingerprint detection method provided in an embodiment of the present disclosure, the embodiment takes the fingerprint detection method as an example for being used in the display screen 100 of the mobile terminal shown in fig. 1, and includes the following steps:
in step S301, a touch operation acting on the display screen of the mobile terminal is detected.
The implementation process of step S301 is referred to step S201, and is not described herein again.
In step S302, it is determined whether the touch operation is applied to the fingerprint detection area of the display screen, and if the touch operation is applied to the fingerprint detection area of the display screen, step S303 is executed. And if the touch operation acts on the area outside the fingerprint detection area of the display screen, exiting the current process.
In an optional implementation manner, whether the touch operation acts on a fingerprint detection area of the display screen may be determined by a touch driving module of the touch control assembly; the touch driving module can also be used for acquiring the position information of the touch operation acting on the touch control assembly and sending the position information to the fingerprint detection driving module or the pressure sensor driving module, and the fingerprint detection driving module or the pressure sensor driving module is used for determining whether the touch operation acts on a fingerprint detection area of the display screen.
In step S303, it is determined whether a pressure value can be obtained by the pressure sensor; if the pressure value can not be obtained through the pressure sensor, executing step S305; if the pressure value can be obtained by the pressure sensor, step S304 is executed.
During the use of the mobile terminal by the user, the following situations may occur, so that the pressure value cannot be obtained through the pressure sensor:
the first condition is as follows: the pressure sensor is damaged and insensitive, and other hardware faults occur, so that the pressure value of the touch pressure generated by the touch operation cannot be acquired through the pressure sensor.
Alternatively, a hardware failure of a pressure sensor may be registered by a parameter, e.g. a failure parameter, which may be a global variable.
Illustratively, the global variable that records the hardware failure of the pressure sensor is bpasshardwareheady, and in the system initialization phase, if the pressure sensor fails to initialize, the value of bpasshardwareheady is given as False, that is, bpasshardwareheady is False; if the pressure sensor initialization is successful, the value of bPresssHardwearReady is assigned to True, i.e., bPresssHardwearReady is True.
Each component in a display screen of the mobile terminal can access or modify the fault parameters; the operating system of the mobile terminal applied in the embodiment of the present disclosure may also access or modify the fault parameter, for example, in an initialization stage of the operating system, perform hardware fault detection on the pressure sensor. When the pressure sensor can not be initialized normally, setting fault parameters as hardware faults; otherwise, the failure parameter is set to no hardware failure.
Case two: communication with the pressure sensor fails, so that the pressure value of the touch pressure generated by the touch operation cannot be acquired by the pressure sensor.
For example, if the pressure sensor is hardware-failure-free and detects that a touch operation is applied to a fingerprint detection area of the display screen, but the pressure value acquired by the pressure sensor is not read within a time threshold after the touch operation is detected, it is determined that the communication with the pressure sensor has failed. The time threshold may be a preset value.
For some users, if the fingerprint detection function of the mobile terminal is unavailable when the pressure sensor is subjected to hardware failure, the pressure sensor must be maintained, the economic cost and the time cost are unnecessary, and the users can accept a certain probability of unnecessary fingerprint detection caused by directly performing fingerprint detection operation without pressure value detection. If the communication failure with the pressure sensor occurs, the fingerprint detection operation can be directly carried out without pressure value detection, so that the fault-tolerant capability of the fingerprint detection process on the pressure sensor is improved. Thus, in one possible implementation, step S303 includes:
judging whether the pressure sensor has hardware faults or not;
if the pressure sensor has a hardware failure, the pressure sensor cannot acquire a pressure value, and step S305 is executed.
Optionally, in this implementation manner, step S303 further includes:
if the pressure sensor has no hardware failure, it is determined whether communication with the pressure sensor has failed, and if communication with the pressure sensor has failed, the pressure sensor cannot acquire a pressure value, and step S305 is executed.
Accordingly, if the pressure sensor has no hardware failure and the communication with the pressure sensor is successful, it indicates that the pressure value can be acquired by the pressure sensor, and step S304 is performed.
In step S304, it is determined whether the pressure value is greater than the pressure threshold, and if the pressure value is greater than the pressure threshold, step S305 is executed. And if the pressure value is not greater than the pressure threshold value, exiting the current process.
If the false touch operation acts on the fingerprint detection area of the display screen, the pressure applied to the fingerprint detection area on the display screen by the false touch is generally not greater than the pressure threshold value. Such false touches may be filtered out by setting a pressure threshold in step S304 to reduce unnecessary fingerprint detection operations.
Alternatively, the pressure threshold is preset, and the pressure threshold may be set based on the touch operation habits of most users; or the operating system of the mobile terminal adjusts according to the touch operation habit of the user using the mobile terminal; or set by application software of the mobile terminal.
In an alternative embodiment, steps S302-S304 may be implemented by the first driving module.
When the first driving module is a touch driving module, the touch driving module obtains information of touch operation (whether the touch operation acts on a fingerprint detection area of the display screen) and obtains pressure information (whether a pressure value and/or the size of the pressure value can be obtained), and the touch driving module executes steps S302-S304 according to the obtained information to obtain a fingerprint detection instruction.
The pressure information includes whether a pressure value and/or the magnitude of the pressure value can be obtained.
For example, if the fault parameter obtained by the touch driving module is a hardware fault, the pressure information obtained by the touch sensor includes a pressure value which cannot be obtained.
In another example, if the touch driving module fails to communicate with the pressure sensor driving module, that is, the pressure value of the touch pressure generated by the touch operation cannot be obtained through the pressure sensor, the pressure information obtained by the touch sensor includes the pressure value that cannot be obtained.
In another example, if the pressure sensor driving module obtains a pressure value, the touch driving module receives the pressure value sent by the pressure sensor driving module, and the pressure information obtained by the touch driving module includes the obtained pressure value and the size of the pressure value.
When the first driving module is a pressure sensor driving module, the pressure sensor driving module obtains pressure information, the pressure sensor driving module receives information of touch operation obtained by the touch driving module, and the pressure sensor driving module executes steps S302-S304 according to the obtained information to obtain a fingerprint detection instruction.
For example, if the fault parameter obtained by the pressure sensor driving module is a hardware fault, the pressure information obtained by the pressure sensor driving module includes a pressure value which cannot be obtained.
In another example, if the pressure sensor driving module does not read a pressure value within a time threshold after the touch operation is detected, the pressure information obtained by the pressure sensor driving module includes a pressure value that cannot be obtained.
In another example, if the pressure sensor driving module obtains the pressure value, the pressure information obtained by the pressure sensor driving module includes the available pressure value and the size of the pressure value.
When the first driver module is a customized fingerprint detection driver module, such as a fingerselect driver module, the customized fingerprint detection driver module receives the information of the touch operation obtained by the touch driver module and receives the pressure information, and the customized fingerprint detection driver module executes the steps S302-S304 according to the obtained information to obtain the instruction of fingerprint detection.
The obtaining manner of the pressure value information is similar to that when the first driving module is a touch driving module, and is not described herein again.
Optionally, the pressure information includes one or more of the following information:
in step S305, the fingerprint chip is controlled to perform a fingerprint detection operation.
In an optional implementation manner, the instruction for fingerprint detection is sent to the fingerprint chip, and the fingerprint chip performs a fingerprint detection operation according to the instruction for fingerprint detection. Illustratively, an instruction for fingerprint detection is sent to the fingerprint chip; the fingerprint chip obtains characteristic information of a fingerprint through a sensor (e.g., an optical sensor, a capacitive sensor, an inductive sensor, etc.).
In a possible implementation manner, whether fingerprint detection can be performed when the pressure value cannot be acquired can be controlled through an operating system or application software of the mobile terminal, so that greater flexibility of use is provided for a user. For this reason, step S303 may be preceded by:
detecting information about whether fingerprint detection is possible or not when a pressure value cannot be obtained by a pressure sensor;
if the pressure value can not be obtained by the pressure sensor, fingerprint detection can be performed, and steps S303-S305 are executed.
If fingerprint detection is not possible when the pressure value cannot be obtained by the pressure sensor, steps S304-S305 are executed.
Optionally, the method of this embodiment may further include: information is set as to whether fingerprint detection is possible or not when a pressure value cannot be acquired by the pressure sensor. For example, an option may be added to a setting menu of the mobile terminal, and when the option is selected or turned on, it indicates that fingerprint detection can be performed when a pressure value cannot be obtained through the pressure sensor. On the contrary, when the option is not selected or closed, the fingerprint detection cannot be performed when the pressure sensor cannot acquire the pressure value.
This touch operation that the detection acted on mobile terminal's display screen, when touch operation acted on the fingerprint detection region of display screen, if can't acquire the pressure value through pressure sensor, directly carry out the fingerprint detection operation for the fingerprint detection function still can be used when pressure sensor goes wrong, thereby has increased the fault-tolerant ability of fingerprint detection flow to pressure sensor.
Referring to fig. 4, which shows a flowchart of a fingerprint detection method provided in an embodiment of the present disclosure, the embodiment takes the fingerprint detection method as an example for being used in the display screen 100 of the mobile terminal shown in fig. 1, and includes the following steps:
in step S401, a touch operation acting on the display screen of the mobile terminal is detected.
The implementation process of step S401 is referred to step S301, and is not described herein again.
In step S402, it is determined whether the touch operation is applied to the fingerprint detection area of the display screen, and if the touch operation is applied to the fingerprint detection area of the display screen, step S403 is executed.
The implementation process of step S402 is referred to step S302, and is not described herein again.
In step S403, whether the pressure sensor has a hardware failure is determined, and if the pressure sensor has a hardware failure, step S405 is executed; if the pressure sensor has no hardware fault, step S404 is executed.
In step S404, it is determined whether communication with the pressure sensor has failed, and if communication with the pressure sensor has failed, step S405 is executed; no communication with the pressure sensor fails, a pressure value is acquired and step S406 is performed.
In step S405, the pressure value is set to a preset value, and step S406 is performed.
Optionally, the preset value is a value greater than the pressure threshold.
In step S406, it is determined whether the pressure value is greater than the pressure threshold, and if the pressure value is greater than the pressure threshold, step S407 is executed. And if the pressure value is not greater than the pressure threshold value, the fingerprint detection process is exited.
The implementation process of step S406 is referred to step S304, and will not be described herein.
In this embodiment, the steps S401 to S402 may be implemented by a touch driving module. The steps S403-S405 may be implemented by a pressure sensor driving module. The steps S406 to S407 may be implemented by the touch driving module or the customized fingerprint detection driving module based on the pressure value transmitted by the pressure sensor driving module.
In step S407, the fingerprint chip is controlled to perform a fingerprint detection operation.
The implementation process of step S407 is referred to step S305, and is not described herein again.
Illustratively, if a hardware fault of the pressure sensor is recorded by using a global variable bPressHardwareReady, a variable FD is used for indicating whether to control a fingerprint chip to perform fingerprint detection; when detecting the touch operation acting on a fingerprint detection area of a display screen, firstly judging the value of bPressHardwareReady; if the value of bPresssHardwareReady is True, continuously acquiring a pressure value; if the pressure value cannot be acquired through the pressure sensor (possibly because the communication with the pressure sensor fails), the fingerprint detection process is quitted; if the pressure value can be obtained through the pressure sensor, judging whether the pressure value is larger than a pressure threshold value; and if the pressure value is greater than the pressure threshold value, assigning the FD as True, and sending the FD value to the fingerprint detection driving module.
In a possible implementation manner, whether fingerprint detection can be performed when the pressure value cannot be acquired can be controlled through an operating system or application software of the mobile terminal, so that greater flexibility of use is provided for a user. For this reason, step S403 may be preceded by:
detecting information about whether fingerprint detection is possible or not when a pressure value cannot be obtained by a pressure sensor;
if the pressure value cannot be obtained by the pressure sensor, fingerprint detection is enabled, and steps S403 to S407 are performed.
If fingerprint detection is not possible when the pressure value cannot be acquired by the pressure sensor, steps S406 to S407 are performed.
Optionally, the method of this embodiment may further include: information is set as to whether fingerprint detection is possible or not when a pressure value cannot be acquired by the pressure sensor. For example, an option may be added to a setting menu of the mobile terminal, and when the option is selected or turned on, it indicates that fingerprint detection can be performed when a pressure value cannot be obtained through the pressure sensor. On the contrary, when the option is not selected or closed, the fingerprint detection cannot be performed when the pressure sensor cannot acquire the pressure value.
This touch operation that the detection acted on mobile terminal's display screen, when touch operation acted on the fingerprint detection region of display screen, if can't acquire the pressure value through pressure sensor, directly carry out the fingerprint detection operation for the fingerprint detection function still can be used when pressure sensor goes wrong, thereby has increased the fault-tolerant ability of fingerprint detection flow to pressure sensor.
In addition, when the pressure value can not be obtained through the pressure sensor, the operation of updating the pressure value into the preset value is carried out, the judgment process of fingerprint detection operation is further simplified, and the fault tolerance and the stability of the fingerprint detection process are improved.
Referring to fig. 5, a block diagram of a fingerprint detection apparatus 500 provided by an embodiment of the present disclosure is shown, where the apparatus 500 includes a touch detection module 510 and a fingerprint detection module 520.
The touch detection module 510 is configured to detect a touch operation acting on a display screen of the mobile terminal.
The fingerprint detection module 520 is configured to control the fingerprint chip to perform a fingerprint detection operation if a pressure value cannot be obtained through the pressure sensor when a touch operation is applied to a fingerprint detection area of the display screen.
The pressure sensor is used for detecting touch pressure of touch operation.
This touch operation that the detection acted on mobile terminal's display screen, when touch operation acted on the fingerprint detection region of display screen, if can't acquire the pressure value through pressure sensor, directly carry out the fingerprint detection operation for the fingerprint detection function still can be used when pressure sensor goes wrong, thereby has increased the fault-tolerant ability of fingerprint detection flow to pressure sensor.
In a possible implementation manner, the fingerprint detection module 520 is configured to control the fingerprint chip to perform a fingerprint detection operation if a hardware failure occurs in the pressure sensor when a touch operation is performed on a fingerprint detection area of the display screen.
Optionally, the fingerprint detection module 520 is further configured to, when the touch operation is applied to the fingerprint detection area of the display screen and the pressure sensor has no hardware fault, control the fingerprint chip to perform the fingerprint detection operation if the communication with the pressure sensor fails.
Optionally, the fingerprint detection module 520 is further configured to control the fingerprint chip to perform a fingerprint detection operation if the touch operation is applied to a fingerprint detection area of the display screen and the pressure sensor obtains a pressure value and the pressure value is greater than a pressure threshold.
In another alternative embodiment, the fingerprint detection module 520 is configured to, when a touch operation is performed on a fingerprint detection area of the display screen, set a pressure value to a preset value if the pressure value cannot be obtained by the pressure sensor; and if the pressure value is greater than the pressure threshold value, controlling the fingerprint chip to perform fingerprint detection operation.
When the pressure value can not be obtained through the pressure sensor, the operation of updating the pressure value into the preset value is carried out, the judgment process of fingerprint detection operation is further simplified, and the fault tolerance and the stability of the fingerprint detection process are improved.
