The first housing 12 and the second housing 14 are relatively far away from each other, and the driving member 50 can drive the flexible display 30 to unfold, so that more flexible display 30 is exposed out of the accommodating space 16.

Because carry out password input and password verification through the flexible operation to flexible display screen, what more is the flexible operation to flexible display screen among the whole password verification process, compare in the correlation technique, manual input digit password or drawing the figure password in touch display screen, the password verification operation that this application embodiment provided can play the effect of covering to the password to terminal password that is caused by other users peeping when having avoided the input password reveals, and then has improved the data security at terminal.

Referring to fig. 6, a flowchart illustrating a password authentication method according to an exemplary embodiment of the present application is shown. The embodiment is described by taking the method as an example applied to the terminal shown in fig. 1 to 5, and the method includes:

step 601, responding to the password input requirement, receiving n times of telescopic operation of the flexible display screen, wherein n is a positive integer.

The flexible display screen comprises a flexible display screen body, a first shell and a second shell, wherein the flexible display screen body comprises a flexible display screen body, the first shell and the second shell are arranged in the flexible display screen body, the stretching operation and the contraction operation are at least one of stretching operation and contracting operation, under the stretching operation, the first shell and the second shell move relatively to increase an exposed display area of the flexible display screen, and under the contracting operation, the first shell and the second shell move relatively to reduce the exposed display area of the flexible display screen.

In an illustrative example, as shown in fig. 7, the stretching operation on the flexible display 702 may be: the first housing 701 is kept at a constant position and the second housing 703 is slid in the direction indicated by the arrow 704, or the second housing 703 is kept at a constant position and the first housing 701 is slid in the direction indicated by the arrow 705; or the first housing 701 is slid in the direction indicated by the arrow 705 while the second housing 703 is slid in the direction indicated by the arrow 704; the retracting operation of the flexible display 702 may be: the first housing 701 remains in place and the second housing 703 slides in the direction indicated by arrow 705; or the second housing 703 remains in place, the first housing 701 slides in the direction indicated by arrow 704; or the first housing 701 is slid in the direction indicated by the arrow 704 while the second housing 703 is slid in the direction indicated by the arrow 705. The embodiment of the present application does not limit the stretching operation received by the terminal.

Aiming at the scene that the password input requirement exists in the terminal, the terminal needs to input a starting password when being started, or the terminal needs to input a screen-up password when being screen-up; or a password is required to be input when a certain application program interface is opened (entered); or a login password is required to be input when a certain application program is logged in; or a check password is required to be input when certain types of privacy information are checked; or a payment password needs to be input when online payment is carried out, and the like.

In a possible implementation manner, when the terminal has a password input requirement, for example, a user needs to check an album and needs to manually input the album to check a password, the user can perform telescopic operation on the flexible display screen, and correspondingly, the terminal can receive the telescopic operation on the flexible display screen and perform subsequent steps of password input, password verification and the like according to the telescopic operation.

Step 602, determining an input password corresponding to n times of telescopic operations according to the size of the exposed display area of the flexible display screen under the telescopic operations.

And n is the digit of the preset password of the terminal, for example, if the user sets the bright screen password of the terminal as a six-digit password, the corresponding n is 6, and the corresponding user needs to perform the telescopic operation for at least 6 times to verify the password.

Because the terminal can change the size of the exposed display area of the flexible display screen through the relative movement of the first shell and the second shell, wherein the size of the exposed display area is variable, the variable corresponds to different input numerical values, that is, the sizes of different exposed display areas are converted into corresponding password numerical values, therefore, in a possible implementation mode, a user can perform n different telescopic operations on the flexible display screen, correspondingly, the terminal converts the sizes of the exposed display areas corresponding to the n telescopic operations into corresponding input numerical values respectively, and determines the n input numerical values as input passwords, that is, password verification can be realized through the telescopic operations on the flexible display screen.

In a possible implementation manner, the size of the exposed area may be represented by a length of a screen edge of the flexible display screen with a length change under a telescopic operation, for example, the size of the exposed area (screen edge length) of the flexible display screen under a first telescopic operation is 5 cm.

In an illustrative example, as shown in fig. 7, when the first housing 701 of the terminal is kept still and the second housing 703 moves in the direction indicated by the arrow 705, the terminal acquires the size of the exposed area of the flexible display screen after the shrinking operation, that is, the length corresponding to the screen edge 706, and determines the input password corresponding to the shrinking operation according to the length of the screen edge 706.

Optionally, a fixed reference value is preset in the terminal at a plurality of specific telescopic positions, for example, if the flexible display screen is in a fully expanded state, that is, the exposed display area of the flexible display screen is the largest, the corresponding reference value is 9, and when the exposed display area corresponding to the flexible display screen is the largest after the telescopic operation, the corresponding input password is 9.

Optionally, if the preset password is a password with n bits having the same numerical value, for example, the preset password is 6 "1", the terminal allows the user to perform single expansion operation, and correspondingly, the terminal receives the single expansion operation on the flexible display screen, so that the input password can be determined according to the size of the exposed display area of the flexible display screen corresponding to the expansion operation, and subsequent password verification operation is performed without repeated expansion operation by the user.

Step 603, performing password authentication on the input password according to the preset password.

The preset password is a preset password before password authentication operation of a user, namely the basis for password authentication.

In a possible implementation manner, after the terminal receives n times of stretching operations, input numerical values corresponding to the n times of stretching operations are determined according to the sizes of the exposed display areas corresponding to the n times of stretching operations respectively, and the n input numerical values are determined as input passwords, that is, the input passwords and preset passwords are compared and verified, and when the verification passes, subsequent operations are performed.

In an illustrative example, please refer to fig. 8, which illustrates an interface diagram of a password authentication process according to an exemplary embodiment of the present application. If the password input scene is an online payment scene, after the terminal enters the payment interface 801, the user clicks the payment control 802 on the payment interface 801, correspondingly, the terminal receives a click operation on the payment control 802, a payment confirmation window 803 is displayed on the upper layer of the payment interface 801, the payment confirmation window 803 is used for prompting the user to input a payment password, at this time, the user does not need to manually input a numerical value in a password input frame 805, the flexible display 804 can be subjected to n times of telescopic operation, correspondingly, the terminal receives the telescopic operation on the flexible display 804, determines the input password and matches the payment password preset by the user, if the matching is successful, the verification is passed, and the payment operation is completed, at this time, the terminal jumps to the payment completion interface 806 from the payment interface 801, the payment completion interface 806 displays prompting information of 'payment completion' and corresponding payment information, used for prompting the user that the online payment is completed.

To sum up, in this application embodiment, when there is the password input demand in the terminal, because the first casing and the second casing of the terminal that has flexible display screen can change the size that exposes the display area of flexible display screen through relative motion, consequently, the terminal can be through receiving flexible display screen's n times flexible operation to obtain flexible display screen's under the flexible operation size that exposes the display area, confirm the input password that n times flexible operation corresponds, thereby carry out password authentication to this input password according to predetermineeing the password. Because carry out password input and password verification through the flexible operation to flexible display screen, what more is the flexible operation to flexible display screen among the whole password verification process, compare in the correlation technique, manual input digit password or drawing the figure password in touch display screen, the password verification operation that this application embodiment provided can play the effect of covering to the password to terminal password that is caused by other users peeping when having avoided the input password reveals, and then has improved the data security at terminal.

In another possible application scenario, the method for password verification through the telescopic operation of the flexible display screen in the embodiment of the application is also suitable for the password setting scenario, namely, the password setting is performed through receiving the telescopic operation of the flexible display screen, so that the password setting process can be prevented from being visible by other users, and the confidentiality of the terminal password is further improved.

In an illustrative example, on the basis of fig. 6, as shown in fig. 9, a flowchart of a password authentication method shown in another illustrative embodiment of the present application is shown, and this embodiment is described by taking as an example that the method is applied to the terminals shown in fig. 1 to 5, where the method includes:

step 901, responding to the password setting requirement, receiving n times of telescopic operation of the flexible display screen, wherein n is a positive integer.

The method and the device for setting the password are used for solving the problem that the password setting requirement exists, and the method and the device for setting the password setting requirement correspond to the scene with the password verification requirement in the previous text, for example, the payment password needs to be set in the payment scene, the privacy checking password needs to be set in the privacy checking scene, the login password needs to be set in the application login scene, the startup password needs to be set in the terminal startup scene, and the like.

In a possible implementation manner, when the terminal is in a scene with a password setting requirement, for example, when the terminal is used for setting a payment password for an online payment application, a user can perform a stretching operation on the flexible display screen, and accordingly, the terminal can receive the stretching operation on the flexible display screen and perform a subsequent password setting step according to the stretching operation.

Optionally, n is related to the number of digits of the set password, for example, if the payment password corresponds to six digits, the corresponding n is 6.

And 902, determining a password to be set corresponding to n times of telescopic operation according to the size of the exposed display area of the flexible display screen under the telescopic operation.

The process of determining the password to be set according to the scaling operation may refer to an implementation of determining the input password according to the scaling operation, which is not described herein in detail in this embodiment.

In a possible implementation manner, a user performs corresponding telescopic operation according to a password required to be set, and correspondingly, the terminal receives n times of telescopic operation and determines the corresponding password to be set according to the size of the exposed display area of the flexible display screen corresponding to the n times of telescopic operation.

Step 903, displaying a password setting confirmation window, wherein a password to be set is displayed in the password setting confirmation window, and the password setting confirmation window is used for prompting whether the password to be set is determined to be a preset password.

In order to avoid the situation that the password setting is wrong due to the telescopic operation error, in a possible implementation manner, after the password to be set is determined by the terminal, the password to be set needs to be displayed so that the user can confirm the password.

Optionally, the terminal may display the password to be set through the password setting confirmation window, and prompt the user whether to determine the password to be set as the preset password.

In an illustrative example, please refer to fig. 10, which illustrates an interface diagram of a password setup process according to an exemplary embodiment of the present application. In the password setting interface 1001, after the terminal confirms the password to be set according to n times of telescoping operation, a password setting confirmation window 1002 is displayed on the upper layer of the password setting interface 1001, and a prompt message "whether xxxxxx is set as the preset password" is displayed in the password setting confirmation window 1002, and a confirmation control 1003 and a return control 1004 are displayed.

And step 904, in response to receiving the confirmation operation of the password setting confirmation window, determining the password to be set as the preset password.

In a possible implementation manner, when a user clicks a confirmation control in a password setting confirmation window, correspondingly, when the terminal receives a confirmation operation on the password setting confirmation window, the password to be set is determined as a preset password; on the contrary, if the user clicks the return control of the password setting confirmation window, it indicates that the password to be set is wrong, and the password setting operation needs to be performed again, and correspondingly, the terminal returns to the previous level interface (namely, the password setting interface) after receiving the return operation of the password setting confirmation window.

In an exemplary example, after the user clicks the confirmation control 1003, and correspondingly, the terminal receives a click operation on the confirmation control 1003, the password to be set is determined as the preset password, and a password setting success prompt message is displayed so as to prompt the user that the password setting is completed, and if the user clicks the return control 1004, and correspondingly, the terminal receives a click operation on the return control 1004, the terminal returns to a previous-level interface, namely, the password setting interface 1001.

Optionally, when the terminal determines that the preset password is the password with the same numerical value, in order to facilitate subsequent password authentication operations by the user, the user does not need to repeatedly perform stretching operations.

In an exemplary example, after the user clicks the confirmation control 1003, and accordingly, the terminal receives a click operation on the confirmation control 1003, and determines that the preset password is the same value, an authentication mode confirmation window 1005 is displayed on the upper layer of the password setting interface 1001, and a prompt message "whether password authentication is performed through a single expansion operation" and a "yes" control 1006 and a "no" control 1007 are displayed in the authentication mode confirmation window 1005, and when the user clicks the "yes" control 1006, and accordingly, the terminal receives a click operation on the "yes" control 1006, and then subsequently performs a password authentication operation, when the terminal receives a single expansion operation, password authentication can be performed according to an input password corresponding to the single expansion operation, and when the user clicks the "no" control 1007, and accordingly, the terminal receives a click operation on the "no" control 1007, and when the password verification operation is subsequently carried out, the terminal can carry out the password verification on the input password according to the digit of the preset password and after n times of telescopic operation corresponding to the digit is received.

Step 905, responding to the password input requirement, and receiving n times of telescopic operation of the flexible display screen.

And 906, determining the input password corresponding to the n times of telescopic operation according to the size of the exposed display area of the flexible display screen under the telescopic operation.

And 907, performing password authentication on the input password according to the preset password.

The embodiments of step 905 to step 907 refer to the above embodiments, and this embodiment is not described herein again.

In this embodiment, the password setting mode that this embodiment shows is gone on before password authentication operation, and then the user is when carrying out password setting and password authentication, all goes on through the flexible operation to flexible display screen, can play the effect of sheltering from to the password in password setting and password authentication link homoenergetic, can further improve the data security at terminal.

Since the numeric code generally corresponds to a numerical range of 0 to 9 and is a positive integer, and the size of the exposed display area of the flexible display screen can be any numerical value, developers need to define in advance a conversion relationship between the size of the exposed display area of the flexible display screen and a numerical value of an input code, for example, an input code is determined according to the edge length of the exposed display area, or a corresponding relationship between the edge length and the input numerical value is defined.

Referring to fig. 11, a flowchart of a password authentication method according to another exemplary embodiment of the present application is shown, where the present embodiment takes the method applied to the terminal shown in fig. 1 to 5 as an example to explain, the method includes:

step 1101, responding to the password input requirement, receiving n times of telescopic operation on the flexible display screen, wherein n is a positive integer.

Step 601 may be referred to in the implementation manner of step 1101, and this embodiment is not described herein again.

Step 1102, obtaining a target edge length of the exposed display area after the mth telescopic operation, where the target edge length is a length of a screen edge in a relative movement direction of the shell, and m is a positive integer less than or equal to n.

Since there is generally one screen edge length that remains unchanged and the other screen edge length that changes with the stretching operation when the first housing and the second housing of the flexible display screen perform the relative motion, for example, when the user performs the stretching operation on the flexible display screen, the screen edge length becomes longer with the action time of the stretching operation, and when the user performs the shrinking operation on the flexible display screen, the screen edge length becomes shorter with the action time of the shrinking operation, in one possible embodiment, the screen edge whose length changes with the stretching operation is defined as the target edge, that is, the screen edge whose target edge is located in the relative motion direction of the housings, and the input value is determined according to the target edge length.

In a possible implementation manner, after the terminal receives the mth telescopic operation on the flexible display screen, the flexible display screen is located at the stop position of the current telescopic operation, that is, the target edge length of the exposed display area after the mth telescopic operation can be obtained, and is used for subsequently converting the target edge length into the mth input numerical value.

Step 1103, determining the mth input value according to the target edge length.

In a possible implementation manner, after the terminal determines the mth telescopic operation, when the target edge length corresponding to the exposed display area of the flexible display screen is determined, the input value corresponding to the mth telescopic operation may be determined according to a conversion relationship between the target edge length and the input value.

In order to facilitate the conversion between the target edge length and the input value, in one possible embodiment, the developer sets a reference edge length corresponding to a reference value, i.e. a password value, in advance for the flexible display screen, for example, the reference edge length corresponding to the reference value "3" is 10.5cm, and defines a unit length representing a distance between adjacent reference values for quantifying the telescopic distance.

In an illustrative example, on the basis of fig. 11, as shown in fig. 12, step 1103 may include step 1103A and step 1103B.

Step 1103A, determining a telescopic distance according to the target edge length and a reference edge length, where the reference edge length is a length of a screen edge in a relative movement direction of the shell when a reference value is input.

The corresponding relationship between the reference value and the reference edge length may be preset by a developer, for example, when the flexible display screen is defined to be completely unfolded, the reference value corresponding to the bottom position of the screen (that is, when the target edge length of the flexible display screen is the maximum) is 0, or the reference value corresponding to the bottom position of the screen is defined to be 9, or when the flexible display screen is in a non-telescopic state, the reference value corresponding to the bottom position of the screen (when the target edge length of the flexible display screen is the minimum) is 0, which is not limited in this embodiment.

In an exemplary example, the correspondence between the reference edge length and the reference value may be as shown in table one:

watch 1

As shown in table one, if the minimum reference edge length is 6cm, it indicates that the flexible display screen does not completely shrink, and there is a minimum exposed display area, and the length of the target edge corresponding to the minimum exposed display area is 6 cm.

Alternatively, the minimum reference edge length may be 0cm, indicating that the flexible display screen may be fully collapsed.

In a possible implementation manner, before the terminal receives n times of telescopic operations, the reference edge length is determined, that is, before the terminal receives the first telescopic operation, the reference edge length corresponding to the exposed display area of the flexible display screen is recorded, and after the terminal receives the mth telescopic operation, the total telescopic distance after the mth telescopic operation relative to the total telescopic distance before the telescopic operation is not performed can be determined by obtaining the target edge length corresponding to the currently exposed display area and making a difference with the reference edge length recorded in advance.

In an illustrative example, as shown in fig. 13, an interface diagram of a reference edge length, a target edge length, and a telescopic distance relationship is shown in an illustrative embodiment of the present application. As shown in fig. 13, before the flexible display screen 1301 does not receive the stretching operation, the reference edge length corresponding to the flexible display screen 1301 is the length corresponding to the screen edge 1302, and when the terminal receives the stretching operation on the flexible display screen 1301, that is, the stretching operation is performed on the flexible display screen 1301 along the direction indicated by the arrow 1303, the length corresponding to the screen edge 1302 after the stretching operation is the target edge length, and the difference value between the target edge length and the reference edge length is the stretching distance corresponding to the stretching operation this time.

In an exemplary example, if the reference edge length is 6cm and the corresponding target edge length after the mth scaling operation is 9cm, the corresponding scaling distance is 3 cm.

And 1103B, determining an mth input numerical value according to the telescopic distance, the unit length and the reference numerical value, wherein the unit length is the telescopic length corresponding to the unit numerical value.

Since the scaling distance corresponds to the actual scaling size, in order to quantify the scaling distance and thus convert the scaling distance into a corresponding input value, in one possible embodiment, the developer defines a unit length in advance, which can realize the conversion between the scaling distance and the input value.

In an exemplary embodiment, the unit length may be a length between adjacent reference values, as shown in table one, i.e., 1.5 cm.

In a possible implementation manner, after the terminal determines the telescopic distance, the telescopic distance may be quantized according to the unit length, and the telescopic distance is converted into an increase/decrease value on the reference value, so that an input value corresponding to the mth telescopic operation may be determined according to the reference value and the increase/decrease value, for example, if the mth telescopic operation is a stretching operation, the input value corresponding to the telescopic distance is subtracted from the reference value, which is the mth input value corresponding to the mth telescopic operation.

In an illustrative example, the correspondence between the input value, the telescopic distance, the unit length, and the reference value may be expressed as:

N＝N₀±|H₁-H₀|/d

wherein N is an input value, H₁Is the target edge length, H₀To refer to the edge length, H₁-H₀For the telescopic distance, d is the unit length, N₀For reference, the choice of the # sign depends on whether it is a stretching operation or a shrinking operation.

Illustratively, if the stretching distance is 3cm, the unit length is 1.5cm, and the reference value is 9, the corresponding value of the stretching distance is 2, and the stretching operation is performed, and as can be seen from table one, the symbol corresponding to the stretching operation should be minus, and the corresponding input value of the stretching operation is 7.

In step 1104, the first-order input value to the nth-order input value are determined as the input password.

In a possible implementation mode, the terminal determines a bit input value every time the terminal receives the expansion operation, records the bit input value in real time, and determines the first bit input value to the nth bit input value as the input password after the expansion operation times reaches the number of bits of the preset password, namely the nth bit input value is determined.

And 1105, performing password authentication on the input password according to the preset password.

Step 603 may be referred to in the implementation manner of step 1105, which is not described herein again.

In this embodiment, the unit length and the corresponding relationship between the input reference value and the reference edge length are defined, so that after the scaling operation is received, the target edge length corresponding to the scaling operation is converted into the input value, and password verification according to the scaling operation is achieved.

In order to facilitate that a user can intuitively stretch the flexible display screen to the screen position corresponding to the password, in a possible application scenario, the terminal can display virtual coordinates on the screen edge of the shell in the relative movement direction according to the reference edge length and the unit length, wherein the virtual coordinates are used for indicating the stretching position corresponding to each numerical value (namely, the password numerical value or the reference numerical value).

Optionally, the coordinate value range of the virtual coordinate corresponds to the password setting range, for example, the coordinate value range is 0-9.

Optionally, the corresponding relationship between the virtual coordinate value and the telescopic position is predefined by a developer, for example, when the flexible display screen is completely unfolded, the telescopic position at the bottom end of the screen is defined as the coordinate origin.

In an illustrative example, please refer to fig. 14, which illustrates a schematic diagram of a password authentication process according to an illustrative embodiment of the present application. As shown in fig. 14, a virtual coordinate 1402 is displayed on the flexible display 1401, the flexible display 1401 has a minimum exposed display area 1406 (an area where a scaling operation cannot be performed), and the length of a screen edge corresponding to the minimum exposed display area 1406 is a reference edge length corresponding to a virtual coordinate value "9"; the length difference between adjacent virtual coordinate values corresponds to a unit length, and the reference edge length is the length of the screen edge corresponding to any virtual coordinate value; when the screen edge 1404 of the flexible display 1401 is contracted in the direction indicated by the arrow 1405, the corresponding target edge length is the length corresponding to the screen edge 1403; the user can perform the stretching operation of the flexible display screen according to the virtual coordinate value, for example, the user performs the stretching operation on the screen edge 1404 along the direction indicated by the arrow 1405, the virtual coordinate value "0" is stretched to the virtual coordinate value "3", and accordingly, the terminal receives the stretching operation on the flexible display screen 1401, that is, the target edge length corresponding to the stretching operation is obtained to determine that the input value is "3".

In this embodiment, through showing virtual coordinate at flexible display screen edge for instruct the flexible position that each password numerical value corresponds, the user of being convenient for carries out the telescopic operation according to virtual coordinate, has improved the accuracy of telescopic operation, thereby has reduced the probability of maloperation.

Because the telescoping operation has a faulty operation, for example, the interval between two telescoping operations is short, the terminal access method identifies whether the telescoping operation is used for inputting a password, or when adjacent passwords are the same value, the corresponding telescoping position is the same position, after the first telescoping operation is performed, if the second telescoping operation is required to correspond to the current telescoping position, the middle telescoping operation at least needs to be performed once, and then the same value can be input.

In an illustrative example, step 1103 may be replaced with step 1501 and step 1502 as shown in fig. 15 on the basis of fig. 11.

Step 1501, obtaining the stay time of the flexible display screen after the mth telescopic operation.

In a possible implementation manner, after the terminal receives the mth telescopic operation, timing is started, so that the stay time of the flexible display screen after the mth telescopic operation is obtained, and the stay time is used for subsequently judging whether the mth telescopic operation is an effective operation, for example, the stay time is 3 s.

Step 1502, in response to the fact that the staying time length is larger than the preset time length threshold, determining an mth input numerical value according to the target edge length.

The preset duration threshold is preset by a developer, for example, the preset duration threshold is 2 s.

In a possible implementation manner, when the terminal obtains that the stay time of the flexible display screen at the telescopic position after the mth telescopic operation is performed is greater than a preset time threshold, for example, the stay time is 5s and is greater than the preset time threshold by 2s, it is determined that the mth telescopic operation is an effective telescopic operation, and then a subsequent step of determining the mth input value according to the target edge length can be performed.

In this embodiment, a preset duration threshold is preset to determine whether the telescopic operation is an effective telescopic operation, and when the stay duration of the flexible display screen at the telescopic position after the mth telescopic operation is greater than the preset duration threshold, it is determined that the telescopic operation is effective, and then an input numerical value can be determined according to the target edge length corresponding to the telescopic operation, otherwise, it is determined that the telescopic operation is invalid, and no input numerical value confirmation operation is performed. By setting the preset time threshold, the influence of invalid telescopic operation on the password verification process can be avoided as much as possible, and the accuracy of password input is improved.

It should be noted that, the validity of the scaling operation is determined by setting the preset duration threshold, and the password setting process in the above embodiment is also applicable.

Because the stretching operation is performed manually, there may be a case where the input value determined according to the target edge length is a decimal, that is, after the corresponding stretching operation, the stretching position corresponding to the flexible display screen is between two adjacent virtual coordinate values.

In an illustrative example, on the basis of fig. 12, as shown in fig. 16, step 1103B may be replaced with step 1601 and step 1602.

Step 1601, determining a candidate input value corresponding to the telescopic operation according to the telescopic distance, the unit length and the reference value.

For the implementation of determining the candidate input value, reference may be made to the above embodiments, which are not described herein again.

In step 1602, a rounding operation is performed on the candidate input value to obtain an mth input value.

The algorithm corresponding to the rounding operation may be preset by a developer, for example, rounding operation, rounding-up operation, rounding-down operation, and the like.

In a possible implementation manner, after the candidate input value is determined, rounding operation needs to be performed on the candidate input value to obtain an input value, which is used for ensuring that the input value is a positive integer.

In an illustrative example, if the candidate input value is 5.1, a rounding operation is performed, corresponding to the input value being 5, if the candidate input value is 5.8, a rounding operation is performed, corresponding to the input value being 6, if the candidate input value is 5, the value is unchanged after the rounding operation, corresponding to the input value being 5.

In this embodiment, rounding operation is performed on the obtained candidate input numerical value so as to ensure that the finally determined input numerical value is a positive integer, and the finally determined input numerical value conforms to the password setting specification, and meanwhile, correction on the telescopic operation can be realized, so that the error in the telescopic operation is avoided, and the password input is mistaken.

In another possible implementation manner, since the terminal of the flexible display screen can automatically extend and retract, the mechanical rotating shaft can be controlled to directly correct the extending and retracting position of the flexible display screen after the extending and retracting operation, so as to directly obtain the target edge length which can be quantized to an integer, and thus the finally obtained input value is also an integer.

In an exemplary example, the implementation of the autonomous correction of the target edge length corresponding to the scaling operation may refer to the following steps:

the method comprises the steps of firstly, obtaining the current edge length corresponding to the mth telescopic operation, wherein m is a positive integer less than or equal to n.

In a possible implementation manner, after the terminal receives the mth telescopic operation, the current edge length corresponding to the mth telescopic operation, that is, the length of the screen edge in the relative movement direction of the housing corresponding to the exposed display area of the flexible display screen, is first obtained.

And secondly, determining the length of the adjacent reference edge corresponding to the current edge length, wherein the length of the adjacent reference edge is the length of the screen edge corresponding to the adjacent input reference value, and the input value corresponding to the current edge length is positioned between the adjacent reference values.

For the way of determining the adjacent reference edge length corresponding to the current edge length, in a possible real-time way, an input value corresponding to the current edge length may be determined first, if the input value is an integer, the adjacent reference edge length does not need to be determined, and if the input value is a decimal, the adjacent reference value corresponding to the input value is determined, so as to determine the adjacent reference edge length corresponding to the adjacent reference value.

In an exemplary case, taking the correspondence relationship between the reference value and the reference edge length as an example shown in table one, when the terminal determines that the current screen edge length is 14cm, the corresponding input value is 3.67, the input value is located between the

adjacent reference values

3 and 4, and the corresponding adjacent reference edge lengths are 13.5cm and 15 cm.

And thirdly, generating a correction instruction according to the minimum difference value between the length of the adjacent edge and the length of the current edge.

In a possible implementation manner, after the terminal determines the adjacent reference edge length, the terminal may generate a corresponding correction instruction by calculating a minimum difference between the adjacent reference edge length and the current edge length, where the correction instruction at least includes a target edge length, and the target edge length is a length of a screen edge corresponding to the minimum difference between the adjacent edge length and the current edge length.

In an exemplary example, if the adjacent reference edge lengths are 13.5cm and 15cm, and the current edge length is 14cm, the corresponding difference values are 0.5cm and 1cm, respectively, and it can be seen that the difference value between the current edge length and the reference edge length 13.5 is the smallest, 13.5cm is determined as the target edge length, and a correction instruction is generated according to the target edge length.

And fourthly, sending a correction instruction to a screen mechanical assembly corresponding to the flexible display screen, wherein the screen mechanical assembly is used for automatically stretching the flexible display screen to the position of the adjacent reference edge length according to the correction instruction.

Wherein, the mechanical part that screen mechanical component instruction control flexible display screen goes on stretching out and drawing back, for example: a driver, a drive structure, etc.

In a possible implementation manner, after the terminal generates the correction instruction, the terminal sends the correction instruction to the screen mechanical assembly, and accordingly, after the screen mechanical assembly receives the correction instruction, the screen mechanical assembly drives the flexible display screen to automatically stretch and contract to the target edge length according to the target edge length indicated in the correction instruction.

In this embodiment, after the terminal obtains the current edge length corresponding to the mth expansion operation, the terminal determines the target edge length according to the relationship between the adjacent reference edge length and the current edge length, and generates a correction instruction according to the target edge length, so that the screen mechanical assembly expands and contracts the flexible display screen to the target edge length according to the correction instruction, and thus the input value determined according to the target edge length conforms to the password value specification (i.e., a positive integer), and the accuracy of the password verification operation is improved.

In one possible embodiment, since the unit length directly affects the input numerical value, in order to further improve the security of the terminal data, if the terminal allows the user to set the unit length by himself, the input numerical values corresponding to the same scaling operation are different, and the security of the password can be further improved.

In an exemplary example, on the basis of fig. 9, as shown in fig. 17, step 901 further includes step 1701 and step 1702.

Step 1701, a length setting operation is received, wherein the length setting operation is used for setting the expansion length corresponding to the unit value.

In a possible implementation manner, a user can set the telescopic length corresponding to the unit value according to the requirement, and correspondingly, the terminal receives the length setting operation.

Step 1702, in response to the target length indicated by the length setting operation being less than the unit length threshold, setting the target length as the unit length, the unit length threshold being determined according to the upper limit of the telescopic length of the flexible display screen.

Since the flexible display screen has an upper expansion limit and the password value has a certain password value range of 0-9, it is necessary to ensure that the set unit value at least divides the flexible display screen into 0-9 values when performing the length setting operation, and therefore, in order to ensure that the unit length set by the user is valid, in one possible embodiment, the terminal is provided with a unit length threshold which is an upper limit set for the unit length and is determined by the upper limit of the expansion length of the flexible display screen, for example, the upper limit of the expansion length of the flexible display screen is 13.5cm, and the corresponding upper limit of the unit length is 1.5 cm.

In a possible implementation manner, after the terminal receives the length setting operation, the terminal obtains a target length corresponding to the length setting operation, compares the target length with a preset unit length threshold, and if the target length is less than or equal to the unit length threshold, for example, the target length is 1cm and is less than the preset unit length threshold by 1.5cm, it indicates that the length setting operation is valid, and determines the target length as a unit length for a subsequent password setting or password verification process.

In this embodiment, by setting the unit length threshold, when a length setting operation is received, whether the length setting operation is valid or not is determined by determining a relationship between a target length corresponding to the length setting operation and the unit length threshold, so as to avoid an invalid length setting operation or an influence on subsequent password setting by the length setting operation that does not conform to the flexible upper limit of the flexible display screen.

It should be noted that, the length setting operation in this embodiment may also be applied before the password verification operation, and the corresponding scaling operations of the same preset password are different, which is not limited in this embodiment of the present application.

Referring to fig. 18, a flowchart of a password authentication method according to another exemplary embodiment of the present application is shown, where the method includes:

step 1801, in response to the password input requirement, receiving n times of telescopic operations on the flexible display screen, where n is a positive integer.

And step 1802, judging whether the stay time of the flexible display screen after the mth telescopic operation is longer than a preset time threshold value.

And if the stay time is longer than the preset time threshold, entering a step 1803, otherwise, entering a step 1806.

Step 1803, determining an mth input numerical value according to the target edge length of the exposed display area after the mth expansion operation, where m is a positive integer less than or equal to n.

And 1804, determining as an input password according to the first input numerical value and the nth input numerical value.

Step 1805, performing password authentication on the input password according to the preset password.

And step 1806, ending.
