Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts Example, shall fall within the protection scope of the present invention.
Referring to Fig. 1, Fig. 1 be the flow chart of fingerprint detection method provided in an embodiment of the present invention, as shown in Figure 1, include with Lower step:
Step 101, the illumination intensity value for detecting mobile terminal local environment.
In a step 101, mobile terminal can detecte the illumination intensity value of mobile terminal local environment, it can detection is outer The illumination intensity value of boundary's environment.Mobile terminal in the embodiment of the present invention, include at least flexible screen, soft shell, mainboard and Battery.Wherein, battery is flexible.Liquid metal can be used in mainboard, and flexible polymer of arranging in pairs or groups.Soft shell and master Plate may include marmem (SMA, Shape Memory Alloy) silk.
Mobile terminal can pass through photosensitive identifier or the illumination intensity value of phase machine testing external environment.It needs to illustrate It is, when the illumination intensity value of external environment is greater than preset first threshold, for example, the illumination intensity value when external environment is greater than When 3000 lux, strong light environment can be considered as；When external environment illumination intensity value be less than preset 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 Greater than preset second threshold and it is less than preset first threshold, i.e., when the illumination intensity value of external environment is greater than 1000 luxs And when less than 3000 lux, normal environment 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 greater than preset first threshold, it can judgement is extraneous Whether the illumination intensity value of environment is greater than 3000 luxs；Or, it can be determined that whether the illumination intensity value of external environment is less than Preset second threshold, it can judge the illumination intensity value of external environment whether less than 1000 luxs.
If the illumination intensity value of external environment is greater than preset first threshold, i.e., if the illumination intensity value of external environment Greater than 3000 luxs, namely when judging that ambient enviroment is strong light environment, it can determine that the illumination intensity value of external environment is full Sufficient preset condition.
Alternatively, if the illumination intensity value of external environment is less than preset second threshold, i.e., if the illumination of external environment Intensity value less than 1000 luxs, namely judge ambient enviroment be dark situation when, can determine the intensity of illumination of external environment Value meets preset condition.
If step 102 detects that the illumination intensity value meets preset 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 of external environment meets preset condition out, 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 based on the received electrical signal to flexible screen Shape-memory alloy wire in the screen in upper bending region applies current signal.Effect of the shape-memory alloy wire in current signal Under can be heated, after the temperature value of shape-memory alloy wire reaches phase transition temperature value, shape-memory alloy wire will be deformed, I.e. shape-memory alloy wire can be bent towards the direction of fingerprint sensor namely flexible screen on be bent region screen can be towards finger The direction of line sensor is bent.After the completion of shape-memory alloy wire deformation, the screen that region is bent in flexible screen can be bent To the top of fingerprint sensor, fingerprint sensor is sheltered from.

Step 103, the control fingerprint sensor carry out fingerprint detection.
In step 103, the time needed for shape-memory alloy wire completes deformation process can repeatedly be measured, it can more Secondary measurement shape-memory alloy wire from start to be deformed to terminate deformation needed for the time.One is determined according to the result repeatedly measured The standard transformations time, and save the standard transformations time.For example, N milliseconds can be set by the standard transformations time.
Mobile terminal can wait N milliseconds after CPU sends control signal to controller.After N milliseconds, i.e., it is believed that Shape-memory alloy wire deforms successfully, next can carry out fingerprint detection using fingerprint sensor.Namely after N milliseconds, No matter whether shape-memory alloy wire deforms success, may be by fingerprint sensor and carries out fingerprint detection.
If shape-memory alloy wire deforms successfully, the screen that region is bent in flexible screen can be bent to fingerprint sensor Top shelters from fingerprint sensor.If mobile terminal, which is in, at this time puts out screen state, screen can be first lighted, then carry out fingerprint Detection.After lighting screen, screen area locating for fingerprint sensor can emit optical signals, and screen locating for fingerprint sensor The brightness for the optical signal that field emission goes out is much larger than the brightness in other regions of screen.
Bending region in flexible screen and it will form an accommodating space between screen, finger can be protruded into the appearance by user In between emptying, and then finger is pressed on fingerprint sensor.The optical signal that screen area locating for fingerprint sensor is launched encounters The finger of user can reflect back, and mobile terminal can be carried out fingerprint recognition according to reflected optical signal.
It, can since the bending region in flexible screen is located at the top of fingerprint sensor when ambient enviroment is dark situation To shelter from the very high optical signal of brightness that screen area locating for fingerprint sensor is emitted, the very high light letter of brightness is avoided Number the eyes of user are emitted directly toward, and then can prevent the very high optical signal of brightness from causing to stimulate to the eyes of user.
It should be noted that the optical signal that screen area locating for fingerprint sensor emits is generally monochromatic optical signal, It may be secondary color optical signal.Sunlight is then polychromatic light.If mobile terminal is non-deformable, and ambient enviroment is the strong ring of light Border, for example, the longer light of sunlight medium wavelength can penetrate the finger of user, at this time fingerprint sensor under sunlight Extra light will be received, and then will affect the acquisition of finger lines, it is final to influence fingerprint recognition success rate.The present invention is implemented Mobile terminal in example can deform, and the screen that region is bent in flexible screen is located at the top of fingerprint sensor, can block Firmly fingerprint sensor.It therefore can be to avoid sunlight to the direct irradiation of the finger by the user on fingerprint sensor, significantly The sunlight leaked into fingerprint sensor is reduced, that is, substantially reduces the light emitted to screen area locating for fingerprint sensor The interference of signal improves fingerprint recognition success rate.
In the embodiment of the present invention, it is outer that above-mentioned mobile terminal can be any flexibility for having built-in shape-memory alloy wire Shell, the mainboard of built-in shape-memory alloy wire, fingerprint sensor and flexible screen mobile terminal.Such as: mobile phone, tablet computer (Tablet Personal Computer), laptop computer (Laptop Computer), personal digital assistant (personal Digital assistant, abbreviation PDA), mobile Internet access device (Mobile Internet Device, MID) or wearable Equipment (Wearable Device) etc..

It, can be according to fingerprint identification region after getting position and the area of the fingerprint identification region of fingerprint sensor Position and area determine the adjusting parameter of flexible screen.Wherein, adjusting parameter may include bending region and bending angle.This is curved Bent angle is the angle being bent between the screen and horizontal plane in region in flexible screen.
As shown in figure 4, for the schematic diagram before flexible screen deformation.Small rectangular area in Fig. 4 is fingerprint identification region 41.
It as fig. 5 a and fig. 5b, is the deformed schematic diagram of flexible screen.In fig. 5, since fingerprint sensor is positioned at soft The lower section of property screen, therefore can be using the horizontal rectangular region of the close fingerprint sensor of flexible screen as above-mentioned bending region.? In Fig. 5 A, the small rectangular area of dashed line form is fingerprint identification region 51, and flexible screen carries out curved area towards fingerprint sensor Domain is bending region 52.
Alternatively, in figure 5B, it can also be using the lower left corner region of the close fingerprint sensor of flexible screen as above-mentioned bending Region.As shown in Figure 5 B, the small rectangular area of dashed line form is fingerprint identification region 53, and flexible screen is carried out towards fingerprint sensor Curved Delta Region is bending region 54.
It should be noted that in the embodiment of the present invention, to region and bending angle is bent with no restriction, as long as buckled zone After domain is bent according to above-mentioned bending angle, fingerprint sensor can be sheltered from.Above embodiment is only a kind of citing Explanation.
Optionally, it is described detection mobile terminal local environment illumination intensity value the step of before, the method is also wrapped It includes: detecting the touch control operation in the flexible screen of mobile terminal；Detect touch-control area of the touch control operation in the flexible screen With the touch-control time of the touch control operation；If detecting, the touch-control area is greater than preset third threshold value, and when the touch-control Between be greater than preset 4th threshold value, then execute it is described detection mobile terminal local environment illumination intensity value the step of.
Put out screen state when mobile terminal is in, fingerprint sensor region can be glimmer state, therefore can to Family prompts the specific touch location on screen.It is possible, firstly, to detect the touch control operation in the flexible screen of mobile terminal, it can inspection Survey the touch operation to the glimmer region on screen.

Optionally, the flexible screen includes shape-memory alloy wire；It is described according to the bending angle, control in flexible screen The direction of screen towards the fingerprint sensor in the bending region is bent, comprising: according to the bending angle, determines electricity Flow the current value of signal；Shape-memory alloy wire in the screen in bending described in flexible screen region is applied described in having The current signal of current value, so that the screen in the bending region is according to the bending angle in the flexible screen, towards the finger The direction of line sensor is bent.
Flexible screen may include shape-memory alloy wire.If the CPU of mobile terminal judges that the illumination of external environment is strong Angle value meets preset condition, then can send a control signal to controller.Controller according to the control signal received again Internally circuit send an electric signal, internal circuit based on the received electrical signal in flexible screen be bent region screen in Shape-memory alloy wire apply current signal.For example, can determine the current value of current signal according to above-mentioned bending angle. Next, the electric current with above-mentioned current value can be applied to the shape-memory alloy wire being bent in the screen in region in flexible screen Signal.Shape-memory alloy wire can be heated under the action of current signal, when the temperature value of shape-memory alloy wire reaches phase After alternating temperature angle value, shape-memory alloy wire will be deformed, i.e., shape-memory alloy wire can be carried out towards the direction of fingerprint sensor The screen that region is bent in bending namely flexible screen can be bent according to bending angle towards the direction of fingerprint sensor.Shape After the completion of memorial alloy deformation of filament, the screen that region is bent in flexible screen can be bent to the top of fingerprint sensor, shelter from finger Line sensor.
Step 207, the control fingerprint sensor carry out fingerprint detection.
In step 207, if shape-memory alloy wire deforms successfully, in flexible screen be bent region screen can be bent to The top of fingerprint sensor, shelters from fingerprint sensor.If mobile terminal, which is in, at this time puts out screen state, screen can be first lighted Curtain, then carry out fingerprint detection.After lighting screen, screen area locating for fingerprint sensor can emit optical signals, and fingerprint The brightness for the optical signal that screen area locating for sensor is launched is much larger than the brightness in other regions of screen.
Bending region in flexible screen and it will form an accommodating space between screen, finger can be protruded into the appearance by user In between emptying, and then finger is pressed on fingerprint sensor.The optical signal that screen area locating for fingerprint sensor is launched encounters The finger of user can reflect back, and mobile terminal can be carried out fingerprint recognition according to reflected optical signal.
