It is illustrated, includes the following steps so that the fingerprint detection method is for the display screen 100 of mobile terminal shown in Fig. 1 as an example：
In step S301, detection acts on the touch operation on the display screen of mobile terminal.
The realization process of step S301 is referring to step S201, and details are not described herein.
In step s 302, judge whether the touch operation acts on the fingerprint detection region of display screen, if the touch is grasped
The fingerprint detection region of display screen is acted on, step S303 is executed.If touch operation acts on the fingerprint detection area of display screen
Region other than domain, exits current process.
In an optional implementation manner, it can determine that the touch operation is by the touch drive module of touch control component
The no fingerprint detection region for acting on display screen；The touch operation can also be obtained by touch drive module act on the touch-control
Location information on component, and it is sent to fingerprint detection drive module or pressure sensor drive module, it is driven by fingerprint detection
Dynamic model block or pressure sensor drive module determine whether the touch operation acts on the fingerprint detection region of display screen.
In step S303, judge whether that pressure value can be obtained by pressure sensor；If can not be passed by pressure
Sensor obtains pressure value, executes step S305；If pressure value can be obtained by pressure sensor, step S304 is executed.
During user uses the mobile terminal, it may occur that following situations, so that pressure sensing can not be passed through
Device obtains pressure value：
Situation one：Pressure sensor is damaged and the hardware faults such as insensitive, so that can not be obtained by pressure sensor
Take the pressure value of touch pressure caused by the touch operation.
Optionally, the hardware fault of pressure sensor can be recorded by a parameter, for example, fault parameter, the ginseng
Number can be global variable.
Illustratively, the global variable for recording the hardware fault of pressure sensor is bPressHardwareReady, is being
