Referring to Fig. 1, Fig. 1 is the flow chart of fingerprint detection method provided in an embodiment of the present invention, as shown in figure 1, including with Lower step：
Step 101, the illumination intensity value for detecting mobile terminal local environment.
In a step 101, mobile terminal can detect the illumination intensity value of mobile terminal local environment, you can outer to detect The illumination intensity value of boundary's environment.Mobile terminal in the embodiment of the present invention, including at least flexible screen, soft shell, mainboard and Battery.Wherein, battery is flexible.Mainboard can use liquid metal, and flexible polymer of arranging in pairs or groups.Soft shell and master Plate can include marmem (SMA, Shape Memory Alloy) silk.
Mobile terminal can pass through photosensitive identifier or the illumination intensity value of camera calibration external environment.Need what is illustrated It is, when the illumination intensity value of external environment is more than default first threshold, for example, when the illumination intensity value of external environment is more than During 3000 lux, strong light environment can be considered as；When the illumination intensity value of external environment is less than default Second Threshold, for example, When the illumination intensity value of external environment is less than 1000 lux, dark situation can be considered as；When the illumination intensity value of external environment More than default Second Threshold and it is less than default first threshold, i.e., when the illumination intensity value of external environment is more than 1000 luxs And when being less than 3000 lux, home can be considered as.
After the illumination intensity value for detecting external environment, it can be determined that it is pre- whether the illumination intensity value of external environment meets If condition.Such as, it can be determined that whether the illumination intensity value of external environment is more than default first threshold, you can to judge the external world Whether the illumination intensity value of environment is more than 3000 luxs；Or, it can be determined that whether the illumination intensity value of external environment is less than Default Second Threshold, you can to judge whether the illumination intensity value of external environment is less than 1000 luxs.
If the illumination intensity value of external environment is more than default first threshold, i.e., if the illumination intensity value of external environment More than 3000 luxs, namely when to judge surrounding environment be strong light environment, it may be determined that the illumination intensity value of external environment is expired Sufficient preparatory condition.
Or if the illumination intensity value of external environment is less than default Second Threshold, i.e., if the illumination of external environment Intensity level is less than 1000 luxs, namely when to judge surrounding environment be dark situation, it may be determined that the intensity of illumination of external environment Value meets preparatory condition.
If step 102, detecting that the illumination intensity value meets preparatory condition, flexible screen is controlled towards the fingerprint sensing The direction of device is bent, to block fingerprint sensor.
In a step 102, if the central processing unit (CPU, Central Processing Unit) of mobile terminal judges The illumination intensity value for going out external environment meets preparatory condition, then can send a control signal to controller.Controller according to Internally circuit sends an electric signal to the control signal received again, and internal circuit is according to the electric signal received to flexible screen Shape-memory alloy wire in the screen of upper bending area applies current signal.Effect of the shape-memory alloy wire in current signal Lower to be heated, after the temperature value of shape-memory alloy wire reaches phase transition temperature value, shape-memory alloy wire will deform, I.e. shape-memory alloy wire can be bent towards the direction of fingerprint sensor, namely the screen of bending area can be towards finger in flexible screen The direction of line sensor is bent.After the completion of shape-memory alloy wire deformation, the screen of bending area can be bent in flexible screen To the top of fingerprint sensor, fingerprint sensor is sheltered from.
