It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the invention by showing examples of the invention.

Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.

Based on the technical problems, the embodiment of the invention provides a fingerprint module control method and electronic equipment, which can improve the efficiency of under-screen fingerprint unlocking. The following detailed description refers to the accompanying drawings.

Fig. 1 is a flow chart illustrating a fingerprint module control method according to an embodiment of the present invention. As shown in fig. 1, the fingerprint module control method provided by the embodiment of the invention is applied to an electronic device, the electronic device comprises at least two screens and a fingerprint module positioned below the screens, and the method comprises steps 110 to 140.

Step 110, obtaining the angle variation of the included angle between every two adjacent screens in at least two screens and the current position of the fingerprint module.

Step 120, determining the moving direction of the fingerprint module and the moving distance of the fingerprint module based on the angle variation of each included angle.

And 130, determining the target position of the fingerprint module based on the moving direction, the moving distance and the current position.

Step 140, controlling the fingerprint module to move from the current position to the target position based on the moving direction.

The specific implementation of each of steps 110-140 is described in detail below.

A specific implementation of step 110 will first be described. In some embodiments, the electronic device has a folding screen that can be folded into at least two screens, i.e., the electronic device includes at least two screens. When the included angle between every two adjacent screens of the folding screen of the electronic device is 180 degrees, the whole folding screen of the electronic device is in an unfolding state.

When the included angle between any two adjacent screens in the folding screen of the electronic device is not equal to 180 degrees, the whole folding screen is in a folding state. When the included angles between the screens of the electronic equipment are different values, the folding screens representing the electronic equipment are in different folding states.

When the folding screen of the electronic device is switched between an unfolded state and a folded state, or the folding screen of the electronic device is switched between different folded states, the included angle between at least one pair of adjacent screens in the electronic screen is changed.

And acquiring the angle variation of the included angle between every two adjacent screens in the at least two screens in the process of changing the included angle between any two adjacent screens of the electronic equipment. Because the folding screen can be buckled into two at least screens, in order to be convenient for the user to carry out fingerprint unblock under the screen, consequently need consider the angle variation of the contained angle between every two adjacent screens, remove fingerprint module to suitable position.

It should be noted that, for any one of the screens in the electronic device, the screen has a first surface and a second surface that are disposed opposite to each other. Wherein the first surface is a display surface. It should be noted that the fingerprint module is located at the second surface side of the screen, i.e. below the screen.

The included angle between every two adjacent screens can be the included angle between the first surfaces of the two adjacent screens or the included angle between the second surfaces of the two screens. The included angle between the first surfaces of the two screens or the included angle between the second surfaces of the two screens is 0-180 degrees. That is, the angle between two adjacent screens is less than or equal to 180 degrees.

In the process of changing the included angle between any two adjacent screens of the electronic equipment, in order to improve the moving instantaneity of the mobile module, the angle change amount of the included angle between every two adjacent screens can be obtained according to a preset time interval.

The specific implementation of step 120 is described in detail below.

In some embodiments, the folding screen of the electronic device may be folded into two screens, a first screen and a second screen, i.e., the electronic device includes the first screen and the second screen.

In some embodiments, the folding screen of the electronic device may be folded into three screens, namely a third screen, a fourth screen, and a fifth screen, the fourth screen being connected between the third screen and the fifth screen.

The specific implementation of step 120 is slightly different in the case of different numbers of screens comprised by the electronic device. The following is a detailed description of the two cases.

First case: the electronic device includes a first screen and a second screen.

It should be noted that, the first screen and the second screen each include a first surface and a second surface opposite to each other, and the first surface is a display surface. That is, the first screen includes a first surface of the first screen and a second surface of the first screen that are disposed opposite to each other. The second screen includes a first surface of the second screen and a second surface of the second screen disposed opposite each other.

In the first case, step 120 comprises: in the process that a first included angle between the second surface of the first screen and the second surface of the second screen is changed within a first preset angle range, if the first angle change amount of the first included angle is a negative value, determining that the moving direction is a first direction; if the first angle variation is a positive value, determining that the moving direction is a second direction; wherein the first direction and the second direction are opposite; the moving distance is determined based on the first angle change amount and the width of the first screen or the width of the second screen.

In some embodiments of the present invention, the first preset angle range may be 0 to 180 degrees, or may be set to other angle ranges according to the folding requirement, which is not limited herein. The first preset angle range is 0 degrees to 180 degrees.

It should be noted that, the first angle between the second surface of the first screen and the second surface of the second screen varies between 0 degrees and 180 degrees, including: the first angle is smaller and larger, and the first angle is smaller and larger.

Case a: the first angle is reduced from large.

If the first included angle is reduced from 0 degrees to 180 degrees, the first screen and the second screen are folded slowly. As an example, as shown in fig. 2, if the first angle is reduced from 180 degrees to 120 degrees, the first screen and the second screen change from an unfolded state to a folded state, and the first angle change amount of the first angle is a negative value, the direction of the fingerprint module is determined as the first direction.

As one example, the first direction is a direction perpendicular to an intersection line of the first screen and the second screen (i.e., a folding line shown in fig. 2), and the first direction is directed from the intersection line to an edge line of the first screen or the second screen parallel to the intersection line. The dash-dot line with the arrow in fig. 2 shows the first direction.

As an example, referring to fig. 3, assuming that the first included angle is 180 degrees, the under-screen fingerprint module is at a middle position of the entire folding screen in the horizontal direction. If the first angle is reduced from 180 degrees to 120 degrees, the fingerprint module is moved from the position of fig. 3 to the position of fig. 4 in the first direction shown in fig. 4.

Under the condition A, the representative user wants to use the folding screen in the folding state, so that the fingerprint module is moved to the first screen or the second screen, the user operation is facilitated, and the fingerprint unlocking efficiency under the screen is improved.

B case: the first angle is small and large.

If the first included angle is changed from 0 degrees to 180 degrees from large to small, the first screen and the second screen in the folded state are unfolded slowly. As an example, as shown in fig. 5, if the first angle is reduced from 120 degrees to 180 degrees, the first screen and the second screen are changed from the folded state to the unfolded state, and the first angle change amount is a positive value, the direction of the fingerprint module is determined as a second direction opposite to the first direction.

As an example, referring to fig. 5, the second direction is a direction perpendicular to an intersection line of the first screen and the second screen (i.e., the folding line indicated in fig. 2), and the second direction is directed from an edge line of the second screen to the intersection line. The dashed-dotted line with the arrow in fig. 5 shows the second direction.

As an example, referring to fig. 5, if the first included angle increases from 120 degrees to 180 degrees, the fingerprint module moves from the position in fig. 4 to the central position of the entire folding screen in the horizontal direction along the second direction.

It should be noted that, whether the fingerprint module is moved to the first screen or the second screen may be predefined, and the first direction and the second direction may be determined.

Under the B condition, the representative user wants to use the folding screen in the unfolded state, so that the fingerprint module is moved to the middle of the whole folding screen, the user operation is facilitated, and the fingerprint unlocking efficiency under the screen is improved.

In some examples, in case a and case B, the moving distance may be determined based on the first angle change amount and the width of the first screen or the width of the second screen.

In some embodiments, if the fingerprint module is moved to the first screen in the process of reducing the first included angle is predefined, the moving distance is determined according to the first angle variation and the width of the first screen.

In some embodiments, if the fingerprint module is moved to the second screen in the process of reducing the first angle is predefined, the moving distance is determined according to the first angle variation and the width of the second screen.

In some embodiments, the width of the first screen may be equal to the width of the second screen, on the basis of which the moving distance a may be calculated using the following expression:

a＝|Δθ1*b1/360| (1)

wherein Δθ1 is a first angle variation, and b1 is a width of the first screen.

In some embodiments, if the fingerprint module is moved to the first screen in the process of reducing the first included angle is predefined, b1 in the formula (1) is the width of the first screen. If the fingerprint module is moved to the second screen in the process of reducing the first included angle is predefined, b1 in the formula (1) is the width of the second screen.

As can be seen from the formula (1), if the first angle is reduced from 180 degrees to 0 degrees, see fig. 6a-6b, the fingerprint module moves from the middle position of the width of the folding screen to the middle position of the width of the first screen, i.e. the total distance the fingerprint module moves is b1/2.

It should be noted that, the fingerprint module does not have to be moved to the middle position of the first screen, but may be moved to other positions convenient for the user to operate, and the parameters in the formula (1) may be modified accordingly.

It should be noted that if the screen of the electronic device is in the folding process, that is, if the included angle between any two adjacent screens in the electronic device is in the changing process, the fingerprint module does not move if the electronic device is out of the screen, the unlocking position on the display interface of the electronic device should be the same as the position of the fingerprint module, so that the user can unlock the fingerprint module displayed on the interface, thereby saving energy consumption.

It should be noted that, if the included angle between the first surface of the first screen and the first surface of the second screen is changed between 0 degrees and 180 degrees, it represents that the user wants to close the screen of the electronic device and does not want to operate on the screen of the electronic device, and the fingerprint module under the screen is not moved.

Second case: the electronic device includes a third screen, a fourth screen, and a fifth screen.

Each of the third screen, the fourth screen and the fifth screen comprises a first surface and a second surface which are opposite, and the first surface is a display surface. That is, the third screen includes a first surface of the third screen and a second surface of the third screen; the fourth screen comprises a first surface of the fourth screen and a second surface of the fourth screen; the fifth screen includes a first surface of the fifth screen and a second surface of the fifth screen.

In the second case, since the electronic device includes 3 screens, if the user changes the folded state of the screen of the electronic device, there are the following C case and D case, and thus step 120 includes step 1201, step 1202, and step 1203.

Step 1201, in the process that the second included angle between the first surface of the third screen and the first surface of the fourth screen is changed within the second preset angle range, and the third included angle between the second surface of the fourth screen and the second surface of the fifth screen is changed within the third preset angle range, determining that the moving direction is the third direction if both the second included angle before the change and the second included angle after the change are greater than or equal to the first preset angle under the condition that the second angle change amount of the second included angle is negative; and if the second included angle before the change and the second included angle after the change are smaller than the first preset angle, determining that the moving direction is the fourth direction.

As an example, the second preset angle range may be 0 to 180 degrees, and the third preset angle range may be 0 to 180 degrees. For example, the first preset angle may be 90 degrees.

Case C: the second angle variation of the second included angle is a negative value, and the third included angle varies between 0 degrees and 180 degrees.

Referring to fig. 7, if the second included angle is reduced from 180 degrees to 120 degrees, that is, the second included angle before the change and the second included angle after the change are both greater than or equal to 90 degrees, the moving direction of the fingerprint module is the third direction. As one example, the third direction is a direction perpendicular to the intersection line of the third screen and the fourth screen (i.e., the first folding line in fig. 7), and the third direction is directed from the first folding line to the intersection line of the fourth screen and the fifth screen (i.e., the second folding line in fig. 7).

Because the second included angle before the change and the second included angle after the change are both greater than or equal to 90 degrees, the third screen does not completely shade the fourth screen, and the fingerprint module moves on the fourth screen, so that the unlocking operation of a user is facilitated.

If the second included angle is reduced from 70 degrees to 60 degrees, namely the second included angle before the change and the second included angle after the change are smaller than 90 degrees, the moving direction is the fourth direction. As one example, the fourth direction is a direction perpendicular to the second folding line, and the fourth direction is directed from the second folding line to an edge line of the fifth screen.

Because the second included angle before the change and the second included angle after the change are smaller than 90 degrees, the third screen slowly shields the fourth screen, and the fingerprint module can be moved to the first surface of the fifth screen, so that the unlocking operation of a user is facilitated.

Step 1202, determining that the moving direction is a fifth direction if the second included angle before the change and the second included angle after the change are smaller than the first preset angle under the condition that the second angle change is a positive value; and if the second included angle before the change and the second included angle after the change are larger than or equal to the first preset angle, determining that the moving direction is the sixth direction.

D case: the second angle variation is positive, and the third included angle varies between 0 degrees and 180 degrees.

If the second included angle is increased from 60 degrees to 70 degrees, that is, the second included angle before the change and the second included angle after the change are smaller than 90 degrees, the moving direction of the fingerprint module is a fifth direction opposite to the fourth direction. As one example, the fifth direction is a direction perpendicular to the second fold line, and the fifth direction is directed from an edge line of the fifth screen to the second fold line.

If the second included angle is increased from 120 degrees to 180 degrees, that is, the second included angle before the change and the second included angle after the change are both greater than or equal to 90 degrees, the moving direction of the fingerprint module is a sixth direction opposite to the third direction. The sixth direction is a direction perpendicular to the first folding line in fig. 7, and is directed from the second folding line to the first folding line.

In case C or D, step 120 includes step 1203. Step 1203, determining a moving distance based on the second angle change amount and the width of the fourth screen and/or the width of the fifth screen.

In some embodiments, the widths of the fourth screen and the fifth screen may be equal, on the basis of which the moving distance a may be calculated using the following expression:

a＝|Δθ2*b2/360| (2)

where Δθ2 is the second angle change amount, and b2 is the width of the fourth screen.

It is assumed that when the entire folding screen is in an unfolded state, that is, the included angle between the third screen and the fourth screen is 180 degrees, the included angle between the fourth screen and the fifth screen is also 180 degrees, and the fingerprint module is located in the middle position of the width of the fourth screen, see fig. 8.

As can be seen from the formula (2), if the second included angle is reduced from 180 degrees to 90 degrees and the included angle between the fourth screen and the fifth screen is 180 degrees, referring to fig. 9, the fingerprint module moves from the middle position of the width of the fourth screen to the intersection position of the fourth screen and the fifth screen along the third direction.

If the second angle is reduced from 90 degrees to 0 degrees, the third screen obscures the fourth screen, and referring to fig. 10, the fingerprint module moves from the intersection position of the fourth screen and the fifth screen to the middle position of the width of the fifth screen along the fourth direction.

It should be noted that, the fingerprint module is not necessarily moved to the middle position of the fifth screen, but may be moved to other positions convenient for the user to operate, and the parameters in the formula (2) may be modified accordingly.

Similarly, if the second included angle increases from 0 degrees to 90 degrees, the fingerprint module moves from the middle position of the width of the fifth screen to the intersection position of the fourth screen and the fifth screen along the fifth direction. Similarly, if the second included angle increases from 90 degrees to 180 degrees, the fingerprint module moves from the intersection position of the fourth screen and the fifth screen to the width middle position of the fourth screen.

In some embodiments, in the second case, since the electronic device includes 3 screens, if the user changes the folding state of the screens of the electronic device, there are also E-case, F-case, G-case, and H-case, so step 120 further includes steps 1204 to 1208.

In step 1204, in the process that the second included angle changes within the second preset angle range, and the fourth included angle between the first surface of the fourth screen and the first surface of the fifth screen changes within the fourth preset angle range, the moving direction is determined to be the sixth direction when the second angle change amount is a positive value and the third angle change amount of the fourth included angle is a negative value.

As an example, the fourth preset angle range may be 0 degrees to 180 degrees.

Case E: the second angle change is positive and the third angle change of the fourth angle is negative.

Referring to fig. 11, if the second included angle increases from 120 degrees to 180 degrees and the fourth included angle decreases from 180 degrees to 120 degrees, the moving direction of the fingerprint module is the sixth direction.

Because the second included angle gradually increases, the fourth included angle gradually decreases, namely the fifth screen gradually shields the first surface of the fourth screen, and the first surface of the third screen gradually appears, the fingerprint module is moved along the sixth direction, so that the user can unlock conveniently.

In step 1205, in the process that the second included angle changes within the second preset angle range, and the fourth included angle between the first surface of the fourth screen and the first surface of the fifth screen changes within the fourth preset angle range, the moving direction is determined to be the third direction when the second angle change amount is negative and the third angle change amount is positive.

In case F, the second angle change amount is a negative value and the third angle change amount is a positive value.

Referring to fig. 11, if the fourth included angle increases from 120 degrees to 180 degrees and the second included angle decreases from 180 degrees to 120 degrees, the moving direction of the fingerprint module is the third direction.

Because the fourth included angle gradually increases, the second included angle gradually decreases, namely the third screen gradually shields the first surface of the fourth screen, and the first surface of the fifth screen gradually appears, the fingerprint module is moved along the third direction, so that the user can unlock conveniently.

In step 1206, in the process that the second included angle changes within the second preset angle range, and the fourth included angle between the first surface of the fourth screen and the first surface of the fifth screen changes within the fourth preset angle range, if the absolute value of the second angle change is smaller than the absolute value of the third angle change, the moving direction is determined to be the sixth direction, and if the absolute value of the second angle change is larger than the absolute value of the third angle change, the moving direction is determined to be the third direction, under the condition that both the second angle change and the third angle change are negative.

In case G, the second angle change amount is a negative value and the third angle change amount is a negative value.

In the case of G, since the second angle variation is negative and the third angle variation is negative, both the third screen and the fifth screen are slowly blocking the first surface of the fourth screen. In order to facilitate unlocking, the sum of the changed second included angle and the changed fourth included angle needs to be limited to be larger than a preset angle threshold value. For example, the preset angle threshold is 240 degrees.

If only the second angle variation is considered to be negative, the moving direction of the fingerprint module should be the third direction, and if only the third angle variation is considered to be negative, the moving direction of the fingerprint module should be the sixth direction, so that the moving trend of the fingerprint module needs to be determined by determining the magnitude between the absolute value of the second angle variation and the absolute value of the third angle variation.

And if the absolute value of the second angle change amount is smaller than the absolute value of the third angle change amount, determining the moving direction as the sixth direction, and if the absolute value of the second angle change amount is larger than the absolute value of the third angle change amount, determining the moving direction as the third direction.

In step 1207, in the process that the second included angle changes within the second preset angle range, and the fourth included angle between the first surface of the fourth screen and the first surface of the fifth screen changes within the fourth preset angle range, if the absolute value of the second angle change is smaller than the absolute value of the third angle change, the moving direction is determined to be the third direction, and if the absolute value of the second angle change is larger than the absolute value of the third angle change, the moving direction is determined to be the sixth direction.

In case H, the second angle change amount is a positive value and the third angle change amount is a positive value.

If only the second angle variation is considered to be positive, the moving direction of the fingerprint module is determined to be the sixth direction, and if only the third angle variation is considered to be positive, the moving direction of the fingerprint module is determined to be the third direction, so that the moving trend of the fingerprint module needs to be determined by judging the magnitude between the absolute value of the second angle variation and the absolute value of the third angle variation.

And if the absolute value of the second angle change amount is smaller than the absolute value of the third angle change amount, determining the moving direction as the third direction, and if the absolute value of the second angle change amount is larger than the absolute value of the third angle change amount, determining the moving direction as the sixth direction.

Step 120 further includes step 1208 of determining a movement distance based on the second angle change, the third angle change, the width of the fourth screen, and/or the width of the fifth screen on an E-case, F-case, G-case, or H-case basis. Wherein the sum of the changed second included angle and the changed fourth included angle is larger than a preset angle threshold.

a＝|(Δθ2–Δθ3)b2/180| (3)

Where Δθ2 is the second angle change amount, Δθ3 is the third angle change amount, and b2 is the width of the fourth screen.

It is assumed that when the whole folding screen is in an unfolded state, that is, an included angle between the third screen and the fourth screen is 180 degrees, an included angle between the fourth screen and the fifth screen is also 180 degrees, and the fingerprint module is located at a width middle position of the fourth screen.

As can be seen from the formula (3), if the second angle is reduced from 180 degrees to 170 degrees, the fourth angle is reduced from 180 degrees to 160 degrees, and the fingerprint module moves b2/18 from the middle position of the width of the fourth screen to the position a on the fourth screen along the sixth direction.

If the second included angle is continuously reduced from 170 degrees to 160 degrees and the fourth included angle is increased from 160 degrees to 180 degrees, the fingerprint module moves B2/6 from the position A to the position B on the fourth screen along the third direction.

If the fourth included angle is reduced from 180 degrees to 160 degrees and the second included angle is continuously increased from 160 degrees to 170 degrees, the fingerprint module moves B2/6 from the position B to the position A on the fourth screen along the sixth direction.

It should be noted that, in step 130, after the current position, the moving direction and the moving distance of the fingerprint module are determined, the final position, i.e. the target position, where the fingerprint module needs to be moved may be determined.

In step 140, after the target position of the fingerprint module is obtained, the fingerprint module is controlled to move to the target position based on the moving direction.

In some embodiments of the present invention, the method for controlling a fingerprint module provided in the embodiment of the present invention further includes: acquiring the angle change rate of each included angle; and determining the moving speed of the fingerprint module based on the angle change speed. On this basis, step 140 includes: and controlling the fingerprint module to move from the current position to the target position based on the moving direction and the moving speed.

In some embodiments, in the first case, the moving speed of the fingerprint module is determined according to the changing speed of the first included angle. As an example, the movement rate of the fingerprint module is positively correlated with the angular change rate of the first included angle. That is, when the user changes the first angle rapidly, the fingerprint module moves rapidly. Otherwise, when the user slowly changes the first included angle, the fingerprint module slowly moves along with the first included angle.

In other embodiments, in the second case, in the case of C and the case of D, the movement rate of the fingerprint module is determined according to the change rate of the second angle. As an example, the movement rate of the fingerprint module is positively correlated with the angular change rate of the second included angle.

And under the conditions of E, F, G or H, determining the moving speed of the fingerprint module according to the changing speed of the second included angle and/or the changing speed of the fourth included angle. As an example, the movement rate of the fingerprint module is positively correlated with the angular change rate of the second included angle or the angular change rate of the fourth included angle. In other embodiments, the movement rate of the fingerprint module may be determined with the greater of the angular rate of change of the second included angle and the angular rate of change of the fourth included angle.

The moving speed of the fingerprint module is determined according to the change speed of the included angle, so that the requirements of users can be considered, and the good experience of the users is improved.

If the electronic device includes more than three electronic screens, the control method of the fingerprint module is similar to the control method of the two cases, and the purpose is to move the fingerprint module to the screen convenient for the user to operate and see, which is not described herein.
