The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

A terminal device, also called a User Equipment (UE), is a device providing voice and/or data connectivity to a User, for example, a handheld device with a wireless connection function, a vehicle-mounted device, and so on. Common terminals include, for example: the mobile phone includes a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), and a wearable device such as a smart watch, a smart bracelet, a pedometer, and the like.

The embodiments of the present invention will be described below with reference to the drawings.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a terminal device 100 according to an embodiment of the present invention, which includes an application processor AP110, an optical fingerprint module 130, and a touch display screen 120, where the touch display screen 120 includes a preset area, the optical fingerprint module 130 is disposed below the preset area,

the AP110 is configured to adjust a focal length of the optical fingerprint module from a first focal length to a second focal length; or, adjusting the optical fingerprint module from a first position to a second position;

the AP110 is further configured to control a light-emitting unit of the preset area to emit light, where the light emitted by the light-emitting unit is used for illuminating a fingerprint of the user;

the optical fingerprint module 130 is configured to collect a fingerprint of a user irradiated by the light emitted by the light emitting unit.

In an example, the touch display screen 120 is one of an LCD display screen, an OLED display screen, and an LED display screen.

In an example, the size of the preset area is not limited to the maximum size of the entire touch display screen, the minimum size of the preset area is the size of a fingerprint that enables a user to enter a sufficient area, and the like.

In an example, the preset area may be disposed at a lower left corner of the touch display screen, a lower right corner of the touch display screen, an upper right corner of the touch display screen, and the like, which is not limited in the present invention.

In an example, the shape of the predetermined area may be circular, square, oval, diamond, etc., and the present invention is not limited thereto.

In an example, the number of the preset areas may be 1 or more, and the present invention is not limited thereto.

In an example, the AP110 is specifically configured to:

when the AP110 detects that the fingerprint of the user, which is acquired last time, does not satisfy the preset condition, adjusting the focal length of the optical fingerprint module 130 from the first focal length to the second focal length; alternatively, the optical fingerprint module 130 is adjusted from a first position to a second position.

Wherein, optical fingerprint module 130 acquires user's fingerprint each time and all corresponds an acquisition time, and the fingerprint of the user who acquires last time refers to the fingerprint of the user who acquires from optical fingerprint module 130 the latest time of present system. For example, the fingerprint of the user that optical fingerprint module 130 acquireed has fingerprint 1, fingerprint 2 and fingerprint 3, and the acquisition time that fingerprint 1 corresponds is time 1, and the acquisition time that fingerprint 2 corresponds is time 2, and the acquisition time that fingerprint 3 corresponds is time 3, and if time 1 and current system time are the closest, then the fingerprint of the last user that acquires of the aforesaid is fingerprint 1.

In an example, when the definition of the fingerprint of the user acquired last time is greater than or equal to a preset definition, determining that the fingerprint of the user acquired last time meets a preset condition; and when the definition of the fingerprint of the user acquired last time is smaller than the preset definition, determining that the fingerprint of the user acquired last time does not meet the preset condition. The preset definition may be user-defined, or may be user-defined by the AP110, and so on.

For example, when there is greasy dirt or drop on the screen, may influence the definition of the user's that optics fingerprint module 130 obtained fingerprint, this kind of condition accessible reduces the focus of optics fingerprint module 130 (i.e. adjust the focus of optics fingerprint module 130 to the second focus from first focus, the second focus is less than first focus), or closes the distance of optics fingerprint module 130 to user's fingerprint (i.e. adjust optics fingerprint module 130 to the second position from the first position, the distance of optics fingerprint module to user's fingerprint is greater than the distance of optics fingerprint module to user's fingerprint when optics fingerprint module is in the first position), so that optics fingerprint module 130 obtains more clearly.

In an example, the AP110 is specifically configured to:

when the AP110 detects that the distance from the optical fingerprint module 130 to the fingerprint of the user changes, adjusting the focal length of the optical fingerprint module 130 from a first focal length to a second focal length; alternatively, the optical fingerprint module 130 is adjusted from a first position to a second position.

In an example, the setting interface of the terminal device includes a display setting, the display setting includes a film sticking setting, and when the content of the film sticking setting currently read by the AP110 is different from the content of the film sticking setting read last time, it is determined that the distance from the optical fingerprint module 130 to the fingerprint of the user changes.

The content of the film sticking setting read by the AP110 each time corresponds to a reading time, and the last reading of the content of the film sticking setting means that the AP110 reads the content of the film sticking setting at the time closest to the current system time. For example, the AP110 reads the contents set in the sticker includes content 1, content 2, and content 3, the reading time corresponding to the content 1 is time 1, the reading time corresponding to the content 2 is time 2, the reading time corresponding to the content 3 is time 3, and if the time 1 is closest to the current system time, the content set in the sticker that is read last time is content 1.

Further, the reading of the content of the film sticking setting by the AP110 is reading the content of a control button in the film sticking setting.

Specifically, as shown in fig. 2, fig. 2 is a schematic interface diagram provided in an embodiment of the present invention. The user can set whether the touch display screen of the terminal device has the film or not in advance through setting the film setting in the display interface in the interface, for example, the user sets whether the touch display screen has the film or not through the control button in the film setting, specifically, if the content of the control button is yes, it indicates that the touch display screen has the film, and if the content of the control button is no, it indicates that the touch display screen does not have the film. The subsequent AP110 may directly read the content of the control button disposed on the touch screen to determine whether the touch screen is pasted with the touch screen.

For example, suppose that the AP110 last read the content of the control button in the film sticking setting as no, and the AP110 currently reads the content of the control button in the film sticking setting as yes. That is, the touch display screen is in a state from no film to a state with a film. The fingerprint information collected by the optical fingerprint module 130 is to ensure that the optical fingerprint module 130 can focus on the touch display screen 120. When the touch display screen 120 is additionally provided with the adhesive film, the distance from the optical fingerprint module 130 to the fingerprint of the user is increased by the adhesive film, and the distance from the optical fingerprint module 130 to the fingerprint of the user is increased. As shown in fig. 3, when touch display screen 120 does not have the pad pasting, optics fingerprint module 130 is focus 1 department at the focus, can clearly gather the fingerprint of hugging closely the user on touch display screen 120, if touch display screen 120 increases the pad pasting, because optics fingerprint module 130 increases to user's fingerprint distance, if the position of optics fingerprint module 130 is unchangeable, optics fingerprint module 130 wants to gather the focus that clear user's fingerprint needs increase optics fingerprint module 130 (for example focus 2 in fig. 3, focus 2 is greater than focus 1).

The focal length 1 corresponding to no film on the touch display screen 120 and the focal length 2 corresponding to the film on the touch display screen 120 are preset. The focal length of the optical fingerprint module 130 corresponding to the film attached to the touch display screen 120 is focal length 2, and the focal length of the optical fingerprint module 130 corresponding to the film attached to the touch display screen 120 is focal length 1.

Further, the number of the focal length 1 may be 1, or may be multiple, and the present invention is not limited thereto. The number of focal lengths 2 may be 1 or more, and the present invention is not limited thereto.

Wherein, the focus of optics fingerprint module 130 can gather clear user's fingerprint when being focus 2 when pasting the pad pasting on the touch-control display screen 120, can gather clear user's fingerprint when the focus of optics fingerprint module 130 is focus 1 when not pasting the pad pasting on the touch-control display screen 120.

For another example, assume that the AP110 last read the content of the control button in the film sticking setting as no, and the AP110 currently reads the content of the control button in the film sticking setting as yes. That is, the touch display screen is in a state from no film to a state with a film. The fingerprint information collected by the optical fingerprint module 130 is to ensure that the optical fingerprint module 130 can focus on the touch display screen 120. When the touch display screen 120 is additionally provided with the adhesive film, the distance from the optical fingerprint module 130 to the fingerprint of the user is increased by the adhesive film, and the distance from the optical fingerprint module 130 to the fingerprint of the user is increased. As shown in fig. 4, when the touch display screen 120 has no adhesive film, the distance from the optical fingerprint module 130 to the fingerprint of the user is 1 distance, so that the fingerprint of the user tightly attached to the touch display screen 120 can be clearly collected. If touch-sensitive display screen 120 increases the pad pasting, because optics fingerprint module 130 increases to user's fingerprint distance, if the focus of optics fingerprint module 130 is unchangeable, optics fingerprint module 130 wants to gather clear user's fingerprint and need reduce the distance of optics fingerprint module 130 to user's fingerprint (for example remove the direction that is close to touch-sensitive display screen 120 with optics fingerprint module in fig. 4, the distance of removal equals the thickness of pad pasting, the thickness of pad pasting is become equal to apart from 2-apart from 1 promptly).

In one example, the terminal device further comprises a light source built in the optical fingerprint module,

the AP is also used for controlling the light source to emit light at a first moment;

the AP is also used for determining the current distance between the optical fingerprint module and the fingerprint of the user according to the first moment and the second moment when the optical fingerprint module receives the light reflected by the adhesive film at the second moment, and determining that the distance between the optical fingerprint module and the fingerprint of the user is changed when the current distance between the optical fingerprint module and the fingerprint of the user is not equal to the latest distance between the optical fingerprint module and the fingerprint of the user.

Wherein, AP110 measures every time the distance of optics fingerprint module 130 to user's fingerprint all corresponds a measuring time, the most recent distance of optics fingerprint module 130 to user's fingerprint refers to the nearest AP110 of current system time and measures the distance that obtains optics fingerprint module 130 to user's fingerprint. For example, the AP110 measures the distance from the optical fingerprint module 130 to the fingerprint of the user, where the distance is 1, 2 and 3, the measurement time corresponding to the distance 1 is time 1, the measurement time corresponding to the distance 2 is time 2, and the measurement time corresponding to the distance 3 is time 3, and if the time 1 is closest to the current system time, the distance from the optical fingerprint module 130 to the fingerprint of the user is distance 1 for the last time.

Specifically, the light source is controlled to emit light at the first time, a part of the emitted light is transmitted to enter the adhesive film after passing through the touch display screen 120, another part of the emitted light is reflected by the touch display screen 120 to enter the optical fingerprint module 130, a part of the light transmitted to enter the adhesive film through the touch display screen 120 is transmitted to enter the air, and another part of the light is reflected to enter the surface of the touch display screen 120 and then is transmitted to enter the optical fingerprint module 130. Because the light that the touch display screen 120 reflects and gets into optical fingerprint module 130 is different with the energy of the light that the pad pasting reflects and gets into optical fingerprint module 130, optical fingerprint module 130 accessible energy size judgement is the light that the pad pasting sent or the light that the touch display screen 120 reflected.

When gathering the fingerprint, need the user to hug closely pad pasting or touch-control display screen 120 with user's fingerprint, consequently optics fingerprint module 130 is the distance of optics fingerprint module 130 to the pad pasting to user's fingerprint. Since the speed of light is known, the current distance from the optical fingerprint module 130 to the film is equal to (second time-first time) the speed of light, and then divided by 2. Since the distance from the optical fingerprint module 130 to the fingerprint of the user is known last time, if the difference between the two distances is different, it represents that the distance from the optical fingerprint module 130 to the fingerprint of the user changes, and vice versa.

When the light source emits light, the touch display screen 120 does not emit light, and thus, whether the distance from the optical fingerprint module 130 to the fingerprint of the user is determined or not is determined by the light source arranged in the optical fingerprint module 130, so that the power consumption of the touch display screen 120 is reduced, and the service life of the touch display screen 120 is prolonged.

In an example, the terminal device further includes a motor 150, the motor 150 is connected to the optical fingerprint module 130, and the AP110 is specifically configured to: the optical fingerprint module is adjusted from a first position to a second position by the motor 150.

Specifically, the motor 150 is connected to the AP110, and the AP110 can adjust the optical fingerprint module 130 from a first position to a second position by controlling the motor 150, wherein the abscissa of the first position is the same as the abscissa of the second position, and the ordinate of the first position is different from the ordinate of the second position.

In an example, when detecting a fingerprint acquisition instruction, the AP110 detects whether a fingerprint of a user acquired last time meets a preset condition; or, whether the distance that detects optics fingerprint module to user's fingerprint changes. The fingerprint collection instruction is sent by the touch display screen 120 to the AP110 when the touch display screen 120 detects a touch operation of a user on the touch display screen 120; alternatively, the fingerprint collection instruction is sent by the fingerprint payment application to the AP110 when the fingerprint payment application detects a certain fingerprint payment, and the like, and the present invention is not limited thereto.

In one example, the second focal length and the second position are each determined by at least one of the following parameters: 1) the fingerprint of the user obtained last time; 2) the distance from the optical fingerprint module to the fingerprint of the user is obtained currently; 3) the current ambient brightness.

For example, the second focal length is determined by the current ambient brightness. Wherein, every ambient light scope corresponds the focus of an optics fingerprint module 130, and when arbitrary ambient light that includes in the ambient light scope I all is greater than arbitrary ambient light that includes in the ambient light scope J, the focus I of the optics fingerprint module 130 that the ambient light scope I corresponds is greater than the focus J of the optics fingerprint module 130 that the ambient light scope J corresponds, and AP110 can confirm the second focus according to the ambient light scope that present ambient brightness falls into. Because the aperture value is 1/the aperture is the diameter of the focus of optics fingerprint module/the bore of optics fingerprint module. It can be seen that the aperture value is inversely proportional to the aperture, and the larger the aperture, the darker the environment, and the smaller the aperture, the brighter the environment. Therefore, the brighter the ambient light, the larger the focal length of the optical fingerprint module is required.

For another example, the second focal length is a fingerprint of the user that was last acquired. Wherein, every definition scope corresponds the focus of an optics fingerprint module, and when the arbitrary definition that includes in definition scope I all was less than the arbitrary definition that includes in definition scope J, the focus I of the optics fingerprint module that definition scope I corresponds is less than the focus J of the optics fingerprint module that definition scope J corresponds, and AP110 can confirm the second focus according to the definition scope that the definition of the user's that acquires the most recent fingerprint falls into. If the definition of the fingerprint of the user acquired last time is low, the fingerprint of the user can be properly amplified (i.e., the focal length of the optical fingerprint module 130 is properly adjusted to be small) to obtain a clearer fingerprint of the user.

For another example, the second focal length is a distance from the current optical fingerprint module to a fingerprint of a user. Wherein, every distance range corresponds the focus of an optics fingerprint module, when the arbitrary distance that includes in distance range I all is greater than the arbitrary distance that includes in distance range J, the focus I of the optics fingerprint module that distance range I corresponds is greater than the focus J of the optics fingerprint module that distance range J corresponds, AP110 can be according to current the second focus is confirmed to the distance range that the distance of optics fingerprint module to user's fingerprint falls into. It is thus clear that when the distance of optics fingerprint module 130 and user's fingerprint changes, AP110 need adjust the focus of optics fingerprint module 130 to guarantee that optics fingerprint module 130 can focus on user's fingerprint.

For another example, the second location is determined by a current ambient brightness. Wherein, the position of an optical fingerprint module 130 is corresponded to every ambient light scope, and when arbitrary ambient light that includes in ambient light scope I all is greater than arbitrary ambient light that includes in ambient light scope J, the distance that position I of the optical fingerprint module 130 that ambient light scope I corresponds is greater than the distance that position J of the optical fingerprint module 130 that ambient light scope J corresponds reaches touch display screen 120 to touch display screen 120, and AP110 can confirm the second focus according to the ambient light scope that present ambient brightness falls into.

For another example, the second location is a fingerprint of the user that was last acquired. Wherein, the position of an optical fingerprint module 130 is corresponded to every definition scope, when the arbitrary definition that includes in definition scope I all is less than the arbitrary definition that includes in definition scope J, the position I of the optical fingerprint module 130 that definition scope I corresponds is less than the distance of the position J of the optical fingerprint module 130 that definition scope J corresponds to the distance of touch display screen 120 to touch display screen 120, AP110 can confirm the second position according to the definition scope that the definition of the user's that acquires the most recent fingerprint falls into. If the definition of the fingerprint of the user acquired last time is low, the fingerprint of the user can be properly amplified (i.e., the focal length of the optical fingerprint module 130 is properly adjusted to be small) to obtain a clearer fingerprint of the user.

For another example, the second location is a distance from the current optical fingerprint module to a fingerprint of a user. Wherein, the position of an optical fingerprint module 130 is corresponded to every distance range, when the arbitrary distance that includes in distance range I all is greater than the arbitrary distance that includes in distance range J, the distance that position I of the optical fingerprint module 130 that distance range I corresponds is less than the distance that position J of the optical fingerprint module 130 that distance range J corresponds to touch display screen 120's distance, AP110 can be according to present the distance range that the distance of optical fingerprint module to user's fingerprint falls into obtains corresponding second focus. It can be seen that, when the distance of optics fingerprint module 130 and user's fingerprint changes, AP110 need adjust the position of optics fingerprint module 130 to guarantee that optics fingerprint module 130 can focus on user's fingerprint.

In an example, the preset region includes N sub-regions, where N is an integer greater than 1, and the AP210 is specifically configured to:

and controlling the light-emitting units of M sub-regions in the N sub-regions to emit light, wherein the horizontal projection of the fingerprint of the user is positioned in the M sub-regions, and M is a positive integer.

Further, the sizes of the N sub-regions are the same, or the sizes of at least two sub-regions in the N sub-regions are different.

Further, the shapes of the N sub-regions are the same, or the shapes of at least two sub-regions among the N sub-regions are different.

For example, as shown in fig. 5, fig. 5 is another interface schematic diagram provided in the embodiment of the present invention. As shown in fig. 5, the size and shape of N sub-regions included in the preset region are the same, and the preset region includes: subregion A to subregion L. Suppose that the horizontal projection of the fingerprint of the user falls into the sub-area B, the sub-area C, the sub-area F and the sub-area G, and at this time, the optical fingerprint module can obtain a clearer fingerprint only by lightening the sub-area B, the sub-area C, the sub-area F and the sub-area G in the preset area. Therefore, on the premise of obtaining a clearer fingerprint, the power consumption of the terminal equipment is further reduced.

Further, the brightness of the light emitted by the light emitting units of the M sub-regions is a first brightness, the current application is fingerprint payment, the current displayed interface of the touch display screen is a payment interface, and the AP210 is further configured to control the light emitting units of the regions of the touch display screen other than the M sub-regions to emit light with a second brightness, where the second brightness is smaller than the first brightness.

Further, the second brightness is the display brightness currently set by the terminal device. For example, as shown in fig. 2, the display brightness currently set by the terminal device 200 is the display brightness of the touch display screen 220 set by the user through the brightness setting item included in the setting interface when displaying the content.

For example, as shown in fig. 6, fig. 6 is another interface schematic diagram provided in the embodiment of the present invention. As shown in fig. 6, the size and shape of N sub-regions included in the preset region are the same, and the preset region includes: subregion A to subregion L. Assume that the user's fingerprint horizontal projection falls within sub-region B, sub-region C, sub-region F, and sub-region G. Because the current application is fingerprint payment, the fingerprint grade required by fingerprint payment is large, and the currently displayed interface is a payment interface, in order to normally display the payment interface and acquire clear fingerprints, the scheme AP210 controls the sub-area B, the sub-area C, the sub-area F and the sub-area G in the preset area to emit light with the first brightness, and controls the area of the touch display screen 220 except for the 4 sub-areas to emit light with the second brightness.

Referring to fig. 7, fig. 7 is a schematic flowchart of a fingerprint acquisition method according to an embodiment of the present invention, which is applied to a terminal device and includes an application processor AP, an optical fingerprint module, and a touch display screen, where the touch display screen includes a preset area, and the optical fingerprint module is disposed below the preset area, and includes the following steps:

s701, the terminal equipment adjusts the focal length of the optical fingerprint module from a first focal length to a second focal length; or, adjusting the optical fingerprint module from a first position to a second position.

S702, the terminal equipment controls the light-emitting units in the preset area to emit light, and the light emitted by the light-emitting units is used for irradiating the fingerprints of the user.

S703, the terminal device collects the fingerprint of the user irradiated by the light emitted by the light emitting unit.

In one example, the touch display screen is one of an LCD display screen, an OLED display screen, and an LED display screen.

In one example, the terminal device adjusts the focal length of the optical fingerprint module from a first focal length to a second focal length; or, the specific implementation manner that the terminal device adjusts the optical fingerprint module from the first position to the second position is as follows: when detecting that the fingerprint of the user acquired last time does not meet the preset condition, the terminal equipment adjusts the focal length of the optical fingerprint module from the first focal length to the second focal length; or the terminal equipment adjusts the optical fingerprint module from a first position to a second position.

Wherein, the fingerprint that the optics fingerprint module acquireed the user every time all corresponds an acquisition time, and the fingerprint of the user that the most recent acquisition refers to the fingerprint of the user that the optics fingerprint module of a time nearest acquireed apart from current system time. For example, the fingerprint of the user that the optics fingerprint module acquireed has fingerprint 1, fingerprint 2 and fingerprint 3, and the acquisition time that fingerprint 1 corresponds is time 1, and the acquisition time that fingerprint 2 corresponds is time 2, and the acquisition time that fingerprint 3 corresponds is time 3, and if time 1 and current system time are the closest, then the fingerprint of the last user that acquires of aforesaid is fingerprint 1.

In an example, when the definition of the fingerprint of the user acquired last time is greater than or equal to a preset definition, determining that the fingerprint of the user acquired last time meets a preset condition; and when the definition of the fingerprint of the user acquired last time is smaller than the preset definition, determining that the fingerprint of the user acquired last time does not meet the preset condition. The preset definition may be user-defined, or may be user-defined by the terminal device, and so on.

For example, when having greasy dirt or drop on the screen, can influence the definition of the user's that the optics fingerprint module was obtained fingerprint, this kind of condition accessible reduces the focus of optics fingerprint module (just be with the focus of optics fingerprint module from first focus adjustment for the second focus, the second focus is less than first focus), or with the distance of optics fingerprint module to user's fingerprint close (just adjust the second position with optics fingerprint module from the first position, the distance of optics fingerprint module to user's fingerprint is greater than the distance of optics fingerprint module to user's fingerprint when optics fingerprint module is in the second position) to make the optics fingerprint module obtain more clear.

In one example, the terminal device adjusts the focal length of the optical fingerprint module from a first focal length to a second focal length; or, the specific implementation manner that the terminal device adjusts the optical fingerprint module from the first position to the second position is as follows: when detecting that the distance from the optical fingerprint module to the fingerprint of the user is changed, the terminal equipment adjusts the focal length of the optical fingerprint module from a first focal length to a second focal length; or, adjusting the optical fingerprint module from a first position to a second position.

In an example, the setting interface of the terminal device includes a display setting, the display setting includes a film sticking setting, and when the content of the film sticking setting read currently by the terminal device is different from the content of the film sticking setting read last time, it is determined that the distance from the optical fingerprint module to the fingerprint of the user changes.

The content of the film sticking setting read by the terminal equipment every time corresponds to a reading time, and the last reading of the content of the film sticking setting refers to the reading of the content of the film sticking setting by the terminal equipment at the time closest to the current system time. For example, the content set by the terminal device to read the film includes content 1, content 2, and content 3, the reading time corresponding to content 1 is time 1, the reading time corresponding to content 2 is time 2, the reading time corresponding to content 3 is time 3, and if time 1 is closest to the current system time, the content set by the last reading of the film is content 1.

Further, the terminal device reading the content of the film sticking setting is reading the content of a control button in the film sticking setting.

Specifically, as shown in fig. 2, a user may set in advance whether a film is on a touch display screen of the terminal device by setting a film setting in a display interface in the interface, for example, the user may set whether a film is on the touch display screen by using a control button in the film setting, specifically, if the content of the control button is yes, it indicates that a film is on the touch display screen, and if the content of the control button is no, it indicates that a film is not on the touch display screen. The subsequent terminal equipment can directly read the content of the control button arranged on the film pasting to determine whether the film pasting is pasted on the touch display screen.

For example, if the terminal device reads the content of the control button in the film pasting setting for the last time, and the content of the control button in the film pasting setting for the current terminal device is yes. That is, the touch display screen is in a state from no film to a state with a film. The collection fingerprint information of the optical fingerprint module is to ensure that the optical fingerprint module can focus on the touch display screen. When the touch display screen increases the pad pasting, the pad pasting has increased the distance between optics fingerprint module to user's fingerprint, and optics fingerprint module can increase apart from user's fingerprint distance. As shown in fig. 3, when the touch display screen does not have the pad pasting, optics fingerprint module is focus 1 department at the focus, can clearly gather the fingerprint of hugging closely the user on the touch display screen, if the touch display screen increases the pad pasting, because optics fingerprint module increases to user's fingerprint distance, if the position of optics fingerprint module is unchangeable, optics fingerprint module wants to gather the focus that clear user's fingerprint needs increase optics fingerprint module (for example focus 2 in fig. 3, focus 2 is greater than focus 1).

The focal length 1 corresponding to the fact that no film is attached to the touch display screen and the focal length 2 corresponding to the fact that a film is attached to the touch display screen are preset. The focus that shows as long as paste the optics fingerprint module that has the pad pasting to correspond on the touch display screen is focus 2, in addition, as long as paste the focus that has the optics fingerprint module that does not correspond on the touch display screen and be focus 1.

Wherein, the focus of optical fingerprint module can gather clear user's fingerprint when being focus 2 when pasting the pad pasting on the touch-control display screen, can gather clear user's fingerprint when the focus of optical fingerprint module is focus 1 when not pasting on the touch-control display screen when having the pad pasting.

For another example, suppose that the terminal device reads the content of the control button in the film pasting setting last time to be no, and the terminal device reads the content of the control button in the film pasting setting currently to be yes. That is, the touch display screen is in a state from no film to a state with a film. The collection fingerprint information of the optical fingerprint module is to ensure that the optical fingerprint module can focus on the touch display screen. When the touch display screen increases the pad pasting, the pad pasting has increased the distance between optics fingerprint module to user's fingerprint, and optics fingerprint module can increase apart from user's fingerprint distance. As shown in fig. 4, when the touch display screen does not have the pad pasting, the distance of optics fingerprint module to user's fingerprint is distance 1 department, can clearly gather the fingerprint of hugging closely the user on the touch display screen. If during touch-control display screen increases the pad pasting, because optics fingerprint module increases to user's fingerprint distance, if the focus of optics fingerprint module is unchangeable, optics fingerprint module wants to gather clear user's fingerprint and need reduce the distance of optics fingerprint module to user's fingerprint (for example remove the direction that is close to touch-control display screen with optics fingerprint module in figure 4, the distance of removal equals the thickness of pad pasting, the distance 2-apart from 1 the thickness of pad pasting promptly for the pad pasting).

In an example, the terminal device further includes a light source built in the optical fingerprint module, and the method further includes:

the terminal equipment controls the light source to emit light at a first moment;

when the optical fingerprint module receives the light reflected by the film at the second moment, the terminal equipment determines the current distance from the optical fingerprint module to the fingerprint of the user according to the first moment and the second moment, and when the current distance from the optical fingerprint module to the fingerprint of the user is not equal to the distance from the optical fingerprint module to the fingerprint of the user for the latest time, the distance from the optical fingerprint module to the fingerprint of the user is determined to be changed.

Wherein, terminal equipment measures at every turn the distance of optics fingerprint module to user's fingerprint all corresponds a measuring time, once recently the distance of optics fingerprint module to user's fingerprint refers to the distance that the nearest terminal equipment of current system time measured and obtains the distance of optics fingerprint module to user's fingerprint. For example, terminal equipment measures the distance that optical fingerprint module has 1, distance 2 and distance 3 to the fingerprint of user, and the measuring time that distance 1 corresponds is time 1, and the measuring time that distance 2 corresponds is time 2, and the measuring time that distance 3 corresponds is time 3, and if time 1 and current system time are closest, then above-mentioned last time the distance of optical fingerprint module to user's fingerprint is distance 1.

Specifically, the light source is controlled to emit light at a first moment, a part of the emitted light is transmitted to enter the film after passing through the touch display screen, the other part of the emitted light is reflected by the touch display screen to enter the optical fingerprint module, one part of the light transmitted by the touch display screen to enter the film is transmitted to enter the air, and the other part of the light is reflected to enter the surface of the touch display screen and then is transmitted to enter the optical fingerprint module. Because the light that the touch-control display screen reflection got into optical fingerprint module is different with the energy of the light that the pad pasting reflection got into optical fingerprint module, and optical fingerprint module accessible energy size is judged whether the light that the pad pasting sent or the light that the touch-control display screen reflected.

When gathering the fingerprint, need the user to hug closely pad pasting or touch-control display screen with user's fingerprint, consequently the distance of optics fingerprint module to user's fingerprint equals the distance of optics fingerprint module to pad pasting. Since the speed of the light is known, the current distance from the optical fingerprint module to the adhesive film is equal to (second time-first time) the speed of the light, and then divided by 2. Since the distance from the optical fingerprint module to the fingerprint of the user is known last time, if the difference between the distance from the optical fingerprint module to the fingerprint of the user is different, the distance from the optical fingerprint module to the fingerprint of the user is represented to be changed, and vice versa.

When the light source emits light, the touch display screen does not emit light, and therefore the light source built in the optical fingerprint module is adopted to determine whether the distance from the optical fingerprint module to the fingerprint of the user is in use, power consumption of the touch display screen is reduced, and the service life of the touch display screen is prolonged.

In an example, the terminal device further includes a motor, the motor is connected to the optical fingerprint module, and the specific implementation manner of adjusting the optical fingerprint module from the first position to the second position is as follows: the terminal equipment adjusts the optical fingerprint module from a first position to a second position through the motor.

Specifically, the motor is connected with the AP, and terminal equipment can make the optical fingerprint module adjust to the second position from first position through AP control motor, and the abscissa of first position and second position is the same, and the ordinate of first position and second position is different.

In an example, when detecting a fingerprint acquisition instruction, the terminal device detects whether a fingerprint of a user acquired last time meets a preset condition; or, whether the distance that detects optics fingerprint module to user's fingerprint changes. The fingerprint acquisition instruction is sent to the AP by the touch display screen when the touch display screen detects the touch operation of a user on the touch display screen; alternatively, the fingerprint collection instruction is sent by the fingerprint payment application to the AP when the fingerprint payment application detects that the fingerprint payment is determined, and the like, and the present invention is not limited.

For example, the second focal length is determined by the current ambient brightness. Wherein, every ambient light scope corresponds the focus of an optical fingerprint module, and when arbitrary ambient light that includes in ambient light scope I all is greater than arbitrary ambient light that includes in ambient light scope J, the focus I of the optical fingerprint module that ambient light scope I corresponds is greater than the focus J of the optical fingerprint module that ambient light scope J corresponds, and terminal equipment can confirm the second focus according to the ambient light scope that current environment luminance falls into. Because the aperture value is 1/the aperture is the diameter of the focus of optics fingerprint module/the bore of optics fingerprint module. It can be seen that the aperture value is inversely proportional to the aperture, and the larger the aperture, the darker the environment, and the smaller the aperture, the brighter the environment. Therefore, the brighter the ambient light, the larger the focal length of the optical fingerprint module is required.

For another example, the second focal length is a fingerprint of the user that was last acquired. Wherein, every definition scope corresponds the focus of an optical fingerprint module, and when the arbitrary definition that includes in definition scope I all was less than the arbitrary definition that includes in definition scope J, the focus I of the optical fingerprint module that definition scope I corresponds was less than the focus J of the optical fingerprint module that definition scope J corresponds, and terminal equipment can confirm the second focus according to the definition scope that the definition of the user's that acquires the most recent fingerprint falls into. If the definition of the fingerprint of the user who acquires last time is lower, can be with the appropriate local enlargeing of carrying on of user's fingerprint (being about to the focus of optics fingerprint module suitably adjusts for a short time) to obtain clearer user's fingerprint.

For another example, the second focal length is a distance from the current optical fingerprint module to a fingerprint of a user. Wherein, every distance range corresponds the focus of an optics fingerprint module, when the arbitrary distance that includes in distance range I all is greater than the arbitrary distance that includes in distance range J, the focus I of the optics fingerprint module that distance range I corresponds is greater than the focus J of the optics fingerprint module that distance range J corresponds, and terminal equipment can be according to current the second focus is confirmed to the distance range that the distance of optics fingerprint module to user's fingerprint falls into. It can be seen that, when the distance of optics fingerprint model 130 and user's fingerprint changes, AP110 need adjust the focus of optics fingerprint module to guarantee that optics fingerprint module can focus on user's fingerprint.

For another example, the second location is determined by a current ambient brightness. Wherein, every ambient light scope corresponds the position of an optical fingerprint module, and when arbitrary ambient light that includes in ambient light scope I all is greater than arbitrary ambient light that includes in ambient light scope J, the position I of the optical fingerprint module that ambient light scope I corresponds is greater than the distance that position J of the optical fingerprint module that ambient light scope J corresponds reaches the touch display screen to the distance of touch display screen, and terminal equipment can confirm the second focus according to the ambient light scope that current ambient brightness falls into.

For another example, the second location is a fingerprint of the user that was last acquired. Wherein, every definition scope corresponds the position of an optical fingerprint module, when the arbitrary definition that includes in definition scope I all is less than the arbitrary definition that includes in definition scope J, the position I of the optical fingerprint module that definition scope I corresponds is less than the distance of the position J of the optical fingerprint module that definition scope J corresponds to the distance of touch display screen to the touch display screen, and terminal equipment can confirm the second position according to the definition scope that the definition of the user's that reachs most recently fingerprint falls into. If the definition of the fingerprint of the user who acquires last time is lower, can be with the appropriate local enlargeing of carrying on of user's fingerprint (being about to the focus of optics fingerprint module suitably adjusts for a short time) to obtain clearer user's fingerprint.

For another example, the second location is a distance from the current optical fingerprint module to a fingerprint of a user. Wherein, the position of an optical fingerprint module of every distance range correspondence, when the arbitrary distance that includes in distance range I all is greater than the arbitrary distance that includes in distance range J, the position I of the optical fingerprint module that distance range I corresponds is less than the distance that the position J of the optical fingerprint module that distance range J corresponds to the distance of touch display screen, and terminal equipment can be according to present the distance range that the distance of optical fingerprint module to user's fingerprint falls into obtains corresponding second focus. It is thus clear that, when the distance of optics fingerprint module and user's fingerprint changes, terminal equipment need adjust the position of optics fingerprint module to guarantee that optics fingerprint module can focus on user's fingerprint.

In an example, the preset region includes N sub-regions, where N is an integer greater than 1, and the specific implementation manner of controlling the light emitting unit of the preset region to emit light includes: and the terminal equipment controls the light-emitting units of M sub-areas in the N sub-areas to emit light, the horizontal projection of the fingerprint of the user is positioned in the M sub-areas, and M is a positive integer.

For example, as shown in fig. 5, the size and shape of N sub-regions included in the preset region are the same, and the preset region includes: subregion A to subregion L. Suppose that the horizontal projection of the fingerprint of the user falls into the sub-area B, the sub-area C, the sub-area F and the sub-area G, and at this time, the optical fingerprint module can obtain a clearer fingerprint only by lightening the sub-area B, the sub-area C, the sub-area F and the sub-area G in the preset area. Therefore, on the premise of obtaining a clearer fingerprint, the power consumption of the terminal equipment is further reduced.

Further, the brightness of the light emitted by the light emitting units of the M sub-regions is a first brightness, the current application is fingerprint payment, and the interface currently displayed on the touch display screen is a payment interface, and the method further includes: and controlling the light emitting units of the areas except the M sub-areas in the touch display screen to emit light with second brightness, wherein the second brightness is smaller than the first brightness.

Further, the second brightness is the display brightness currently set by the terminal device. For example, as shown in fig. 2, the display brightness currently set by the terminal device is the display brightness of the touch display screen, which is set by the user through the brightness setting item included in the setting interface, when displaying the content.

For example, as shown in fig. 6, the size and shape of N sub-regions included in the preset region are the same, and the preset region includes: subregion A to subregion L. Assume that the user's fingerprint horizontal projection falls within sub-region B, sub-region C, sub-region F, and sub-region G. Because the current application is fingerprint payment, the fingerprint grade required by the fingerprint payment is larger, and the interface displayed currently is a payment interface, in order to normally display the payment interface and acquire clear fingerprints, the terminal equipment controls the subarea B, the subarea C, the subarea F and the subarea G in the preset area to emit light with first brightness, and controls the area of the touch display screen except the 4 subareas to emit light with second brightness.

when at the second moment optical fingerprint module received the warp the light of pad pasting reflection, according to first moment with the second is constantly confirmed the distance of optical fingerprint module to user's fingerprint, works as optical fingerprint module is not equal to the most recent to the present distance of user's fingerprint when the distance of optical fingerprint module to user's fingerprint, then confirms optical fingerprint module changes to the distance of user's fingerprint.
