Formula, this is apart from detection pattern for detecting the distance between screen and object.
Wherein, talking state includes: to connect/make a phone call, voice-over-net call or play voice messaging etc., the embodiment of the present disclosure
To this without specifically limiting.
In the embodiment of the present disclosure, since terminal can carry out fingerprint detection, optical finger print by optical fingerprint sensor
The reflected light signal of different light intensity can be converted to electric signal, since distance can be with base when receiving reflected light by sensor
It is calculated in the propagation of light or the decaying of light intensity, therefore, terminal can be carried out based on optical signal apart from detection.
Wherein, generally, terminal is that is to say in fingerprint detection mode, can automatic root when there is finger to press screen
Fingerprint detection is carried out according to the electric signal of optical fingerprint sensor, and then refers to no longer progress fingerprint detection apart from detection pattern, and
It is that the electric signal based on optical fingerprint sensor is carried out apart from detection.Wherein, handoff procedure includes: when terminal is on call
When, terminal generates switching command, by fingerprint detection pattern switching extremely apart from detection pattern, to come between detection object and screen
Distance.
In step 302, terminal is detected between screen and user under detection pattern by optical fingerprint sensor
Distance.
In actual scene, the electric signal that terminal can be sent under detection pattern according to optical fingerprint sensor, meter
The distance between screen and user are calculated, the method for the calculating distance has following two:
(1) declining between the light intensity for the reflected light that terminal is received according to optical fingerprint sensor and the light intensity for emitting light
Subtract, calculates the distance between screen and user.
Light can generate the decaying of different situations due to the difference for the distance propagated in the medium, and light intensity is caused to become
Change, so terminal can be according to declining between the light intensity for the reflected light that optical fingerprint sensor receives and the light intensity of transmitting light
Subtract, come calculate screen between user at a distance from.
In the embodiment of the present disclosure, when the user approaches the screen, the OLED light issued can be reflected into optical finger print and passed by user
On the photoinduction array of sensor, after the reflected light of photoinduction array received to different light intensity, the optical signal received is converted to
Then electric signal is sent to terminal by electric signal, terminal by fingerprint detection pattern switching to after detection pattern, can basis
Difference between the light intensity for the reflected light that the electric signal received is reflected and the known light intensity for emitting light calculates screen and uses
Distance between family.It is, of course, also possible to a variety of factors for influencing light intensity of comprehensive analysis, which includes: use
Family is to the absorptivity of light, reflectivity, the attenuation of the basic value of reflective light intensity or light intensity in different media etc., the disclosure
Embodiment is to this without specifically limiting.
Wherein, when the basic value of reflective light intensity is that screen is blocked by black object, received by optical fingerprint sensor
The light intensity of reflected light.In order to achieve the purpose that accurately to calculate distance between screen and user by reflective light intensity, in the life of terminal
During production, technical staff can also carry out bottom to the optical fingerprint sensor in terminal and make an uproar detection, determine the base of reflective light intensity
Plinth value, the carry out bottom are made an uproar the process of detection are as follows: are blocked optical fingerprint sensor using black object, obtained optical finger print at this time and pass
Sensor receives the light intensity of reflected light, and the light intensity of reflected light at this time is determined as to the basic value of reflective light intensity.Wherein black object
It can be the black object of the other materials such as black rubber object, countermeasure of the embodiment of the present invention is without specifically limiting.
(2) terminal is according between the launch time of transmitting light and the receiving time of the received reflected light of optical fingerprint sensor
Time difference and light spread speed, calculate the distance between screen and user.
Since screen is different at a distance from user, the transmission range that will lead to light changes, reflected light the light velocity not
In the case where change, distance will affect the time that optical fingerprint sensor receives reflected light, so terminal can be according to transmitting light
Launch time and optical fingerprint sensor receive reflected light receiving time time difference, come calculate between screen and user away from
From.
In the embodiment of the present disclosure, terminal by fingerprint detection pattern switching to after detection pattern, when terminal receives light
Feel array send electric signal when, according to the receiving time for the electric signal for receiving reflected light and transmitting light launch time etc.,
Calculate screen between user at a distance from, it is, of course, also possible to the factor of a variety of influence times of comprehensive analysis, a variety of influence times
Factor includes: the spread speed etc. of reflected light in different media, and the embodiment of the present disclosure is to this without specifically limiting.
In step 303, it is default to judge whether the distance between screen and user are greater than according to the distance detected for terminal
Distance threshold, if it is, continuing distance detection, if not, executing step 304.
Wherein, pre-determined distance threshold value can according to screen during talking process between user at a distance from, the basis of reflective light intensity
The ethnic group in region locating for the temperature or terminal in region locating for value, terminal etc. determines.In actual scene, controlled to reach according to distance
The purpose of screen processed, technical staff can calculate the minimum range between screen and user, and at end in the production process of terminal
Calculated minimum range is set as pre-determined distance threshold value on end.
When the distance between screen and user are greater than pre-determined distance threshold value, it may be considered that user is not close to screen,
Also false triggering would not be caused, therefore, screen go out and shield control, but continues distance detection, Zhi Daotong
After speech phase, fingerprint detection mode is switched back into apart from detection pattern by current.
In step 304, when terminal detects the distance between screen and user no more than pre-determined distance threshold value, detection
Close to the area of the object of screen.
In actual scene, when terminal is on call, when user wants to operate the function button on screen,
If because terminal detect screen between user at a distance from no more than pre-determined distance threshold value, to control screen closing, then can lead
Applying family can not be to the carry out normal operating of function button on screen.Such as user wants by finger etc., in operation display
Function button, the embodiment of the present disclosure is to this without concrete restriction.Under talking state, when the finger of user is close to screen, eventually
If end according to the finger of calculated user between screen at a distance from, determine that the distance between screen and the finger of user are not more than
When pre-determined distance threshold value, control screen goes out screen, then the control screen that will lead to end-error goes out screen.So terminal in order to prevent
Error control occurs, it, can also be according to inspection when terminal determines the distance between screen and user no more than pre-determined distance threshold value
The area of the object close to screen measured goes out screen to determine whether needing to control screen, to facilitate user's energy under talking state
Normal operating is enough carried out to terminal by finger.
When there is object proximity screen, after the light that OLED is issued is got on object, the light sensation battle array on optical fingerprint sensor
Column can receive the reflected light that object is reflected back, and the area of object proximity screen is bigger, receives reflected light on light sensation array
The quantity of light sensation original part will be more, so terminal can be according to the light sensation original part for receiving reflected light on optical fingerprint sensor
Quantity, area, the basic value of light sensation original part for receiving reflected light of light sensation original part etc., calculate close to the face of the object of screen
Product.
Wherein, when the basic value for receiving the light sensation original part of reflected light is that screen is blocked by black object, optical finger print is passed
The quantity of the light sensation original part of reflected light received by sensor, the basic value for receiving the light sensation original part of reflected light can make an uproar inspection the bottom of at
It is obtained during survey.
In step 305, it is default to judge whether the area close to the object of screen is greater than according to the area detected for terminal
Area threshold, if so, 306 are thened follow the steps, if not, continuing area detecting.
Wherein, preset area threshold value can according to user in communication process close to screen area, receive reflected light
The ethnic group in region locating for the temperature or terminal in region locating for the basic value of light sensation original part, terminal etc. determines.In actual scene, in order to
Achieve the purpose that control screen according to area, technical staff can calculate the object close to screen in the production process of terminal
Maximum area, and calculated maximum area is set as preset area threshold value at the terminal.
When detect close to the object of screen area be less than pre-determined distance threshold value when, even if between screen and user away from
From being not more than pre-determined distance threshold value, it is also assumed that user wants to carry out normal operating to terminal under talking state, it therefore, can be with
Screen go out and shield control, but continue area detecting, after talking state, by current area detecting
Pattern switching refers to line detection pattern.
Within step 306, when terminal detect the area close to the object of screen be greater than preset area threshold value and screen with
When the distance between user is not more than pre-determined distance threshold value, control screen goes out screen.
The screen control method provided in the embodiment of the present invention is controlled for OLED screen curtain.Above-mentioned control screen
The mode of screen of going out can be realized by mode electric under terminal control OLED.In fact, terminal stops to lead after powering to OLED
OLED is caused no longer to emit beam, so that screen is in black state, no longer display is appointed again while keeping normal talking state
What function button, to go out screen by controlling screen come the false triggering for preventing user to function button.
The method that the embodiment of the present disclosure provides, by when terminal is on call, using optical fingerprint sensor come
Detect screen between user at a distance from, when the user approaches the screen, the screen that goes out can be carried out to screen, to avoid to screen mistake touch
