In step S12, when determining the position coordinates of one touch signal and the touch duration, the determination of the position coordinates is before the touch duration determination. Specifically, first, it is determined whether the position coordinate is consistent with the preset value (the preset value is the position coordinate corresponding to the unlocked position), and if not, the step of prompting the error is entered: prompting the user to input an error and returning to step S11 to perform the unlocking operation again. Optionally, after prompting the user to input an error, the user is further prompted to wait for a few seconds (for example, 15 seconds) to input the error three times (for example, 15 seconds) before re-opening the operation. If the location coordinates are consistent with the preset value, then the judgment is made. Whether the touch duration of the touch signal is consistent with the preset value (here, the preset value is the touch duration of the unlocked position when the corresponding unlocked position is set), and optionally, the touch screen is in the process of the user touching an unlocked position. The time that has been touched is dynamically displayed near the unlocked position to prompt the user for the touched time of the unlocked position.

Step S22: determining whether the receiving order of the touch signals is consistent with the preset order of receiving the touch signals, and if they are consistent, performing the subsequent steps.

In step S22, the unlocking sequence of the plurality of unlocking positions is preset, and if the touch signal is not received in the preset order, that is, the user does not touch the unlocking position in the preset order, the first embodiment of the screen unlocking method of the present invention is entered. Similar steps to prompt the error, and returning to step S21 to restart the unlocking, if the user touches the unlocked position in the preset order, the user continues to perform the touch action until the order of receiving is inconsistent, then enters the step of prompting the error, and returns In step S21, the unlocking is restarted. If the user clicks on all the unlocked positions to prove that the receiving order is the same, the process proceeds to step S23. In other embodiments, when judging the receiving order, the user may wait for the user to click all the unlocked positions to complete the touch sequence after the touch is completed. If the order of the touches is the same, the process proceeds to step S23. Then enter the step of prompting the error, and return to step S21 to restart the unlocking.

Step S23: sequentially determining whether the position coordinate of each touch signal and the touch duration are consistent with the preset value, and if they are consistent, unlocking the touch screen.

In step S23, the execution process is similar to step S12 of the first embodiment of the screen unlocking method of the present invention, and details are not described herein.

Please refer to FIG. 3. FIG. 3 is a flowchart of a third embodiment of the screen unlocking method of the present invention. The screen unlocking method of this embodiment adds the following steps on the basis of the first embodiment (before step S11):

Step S31: Display a touch point prompt on the touch screen at a position corresponding to the value of the preset position coordinates.

In step S31, the position corresponding to the value of the preset position coordinate is the unlocked position set by the user, and the touch prompt is used to prompt the user to set the unlocked position in advance. This step can satisfy those that do not want the unlocking method to be too complicated. User requirements that lead to forgetting.

Step S41: Display a touch point prompt on the touch screen at a position corresponding to the value of the preset position coordinates.

In step S41, the touch point prompt is displayed to be sequentially displayed, that is, the user displays the second touch point prompt after tapping the previous touch point prompt, and the touch point prompt is displayed in the order of being unlocked in advance. The unlocking order of the positions is the same, and the user can be prompted to unlock the order of the positions, and meet the user requirements that do not want the unlocking method to be too complicated to forget. Of course, in other embodiments, the display touch point prompt may also display the preset unlock position directly on the touch screen without displaying in order to increase the security of the unlock.

Step S42: The user touches the point prompt to generate a corresponding touch signal.

Please refer to FIG. 5. FIG. 5 is a schematic structural diagram of a fifth embodiment of the screen unlocking method of the present invention. In this embodiment, the screen unlocking method includes:

Step S51: Simultaneously receiving at least one touch signal from the touch screen, each touch signal corresponding to the user's touch action on a position on the touch screen.

In step S51, the touch screen is divided into a plurality of positions arranged in a matrix, and the user presets a single position or a plurality of positions as the unlocked position while receiving at least one touch signal from the touch screen, each touch signal and a position on the touch screen of the user. The touch action is one-to-one correspondence, that is, the user simultaneously touches a plurality of unlocked positions and generates corresponding touch signals, and the maximum number of positions that the user can set is consistent with the maximum number of touch points supported by the touch screen.

Step S52: determining whether the position coordinate and the touch duration of each touch signal are consistent with the preset value, and if they are consistent, unlocking the touch screen.

In step S52, when determining the position coordinates of one touch signal and the touch duration, the determination of the position coordinates is before the touch duration determination. Specifically, first, it is determined whether the position coordinate is consistent with the preset value. If not, the step of prompting the error is entered: prompting the user to input an error and returning to step S51 to perform the unlocking operation again, optionally, prompting the user to input the error and prompting the user to If you enter three errors, wait for a few seconds (for example, 15 seconds) before you can re-unlock. If you determine that the position coordinates are consistent with the preset values, then determine whether the touch duration of the touch signal is consistent with the preset value. In the process of the user touching an unlocked position, the touch screen dynamically displays the touched time near the unlocked position to prompt the user for the touched time of the unlocked position. In order to facilitate the user's operation, in the embodiment, the touch durations of the plurality of unlocked positions set in advance are set to be equal. Of course, in other embodiments, in order to improve security, the touch durations of the plurality of unlocked positions may be set to be equal. .

Please refer to FIG. 6. FIG. 6 is a schematic structural diagram of a sixth embodiment of the screen unlocking method of the present invention. The screen unlocking method of this embodiment adds the following steps on the basis of the fifth embodiment (before step S51):

In step S61, the position corresponding to the value of the preset position coordinate is the unlocked position, the touch point prompt is displayed all on the touch screen at one time, and the touch prompt is used to prompt the user to click the touch point prompt, the step may be Meet the needs of users who don't want to unlock too complexly to forget.

Step S62: The user touches the point prompt to generate a corresponding touch signal.

In step S62, the user simultaneously touches a plurality of touch point prompts with a plurality of fingers.

Please refer to FIG. 7. FIG. 7 is a flow chart of a preferred embodiment of the on-screen locking method of the present invention. In this embodiment, the on-screen locking method includes:

Step S71: Receive at least one touch signal from the touch screen, and each touch signal has a one-to-one correspondence with a user's tap action on a position on the touch screen.

In step S71, the user enters the on-screen lock interface, and the interface prompts the user to touch the touch screen to set the unlock position. It is worth noting that, in order to further ensure security, the unlocking mode is too obvious or single. In this embodiment, multiple unlocking positions are preferred. For discrete settings, the degree of dispersion has a specific rule that only one unlocking position can be set in an area containing multiple locations. For details, please refer to FIG. 8. FIG. 8 is a schematic diagram showing the setting of an unlocking position in the on-screen locking method of the present invention. For example, if the user needs to set three unlocking positions D1, D2, and D3, the plurality of non-overlapping A, B, and C areas included on the touch screen are randomly prompted, and the user is prompted to set one of the unlocking positions D1 in the A area. The unlock position D2 is set in the B area, and the unlock position D3 is set in the C area. Each unlocked position corresponds to the touch duration of the user at the time of setting.

Step S72: Analyze the position coordinates and the touch duration of each touch signal, and save them as preset values.

In this embodiment, before step S71, the method further includes setting the unlock type as sequential unlocking or simultaneous touch unlocking.

The first embodiment corresponding to the screen unlocking method of the present invention or the second embodiment of the screen unlocking method of the present invention is sequentially unlocked, and the sequential unlocking includes two types: one is to lock the screen in order to perform the screen unlocking including the sequential judgment. In the method, the chronological order in which the user sets each unlocking position is pre-stored (ie, the order of receiving the touch signals, that is, the order in which the user touches the position on the touch screen), and the other is the order in which the user unlocks the position when unlocking. However, the order judging step is not included, that is, the user does not judge whether the touch order of the unlock position is correct when unlocking. In this embodiment, in order to improve security, when the unlock type is set to sequential unlocking, the touch durations of the respective unlocked positions are set to be different.

Simultaneously, the touch unlocking corresponds to the fifth embodiment of the screen unlocking method of the present invention. Preferably, in the embodiment, if the user sets the unlocking type to simultaneous unlocking, the touch durations of the plurality of unlocked positions are set to be equal to facilitate the user. Operation, of course, in other embodiments, in order to improve security, the touch durations of the plurality of unlocked positions may also be set to be unequal. Optionally, during a process in which the user touches an unlocked position, the touch screen dynamically displays the touched time near the unlocked position to prompt the user for the touched time of the unlocked position.

In this embodiment, on the one hand, the degree of dispersion of the plurality of unlocking positions is large, and on the other hand, when the order is unlocked, the touch time of each point is different, and the judgment of setting the touch order of the unlocked position is also provided, and the combination of the three makes the screen safe after the lock. Sexually high, if you are not concentrating on the voyeuristic screen, it is difficult for others to remember the unlocking process. Users can flexibly set security according to their needs. For example, choose whether to set the touch order judgment, select the touch duration of each unlock position to be equal or unequal, select the number of touch points, etc., from low to high security. The requirements are met by the user's settings.

Please refer to FIG. 9. FIG. 9 is a schematic structural diagram of a module of a preferred embodiment of the mobile terminal of the present invention. In the implementation of the present invention, the mobile terminal includes: a display module 91, a touch sensing module 92, an analysis comparison module 93, and an unlock execution module 94.

The touch sensing module 92 is configured to receive a touch action of the user at at least one location on the touch screen and generate a corresponding number of touch signals according to the touch action.

The parsing and contrasting module 93 is configured to receive and parse the coordinate position and the touch duration included in each touch signal and compare the preset values with the preset value. Preferably, the parsing and comparing module 93 is further configured to compare whether the receiving sequence of the touch signal is determined. Consistent with the preset.

The unlocking execution module 94 is configured to unlock the touch screen when the parsing comparison module determines the coordinate position and the touch duration included in each touch signal and agrees with the preset value.

The display module 91 is configured to display a touch point prompt on a position corresponding to the value of the preset position coordinates on the touch screen. Preferably, the display module 91 is further configured to prompt the user for the touched time of the unlocked position, for prompting the user to unlock successfully after the unlocking execution module 94 is unlocked, and also for prompting the user to unlock the position that can be set, as shown in FIG. 8 As shown, it is not described here.

Different from the prior art, the present invention can improve the security of the screen unlocking of the mobile terminal by setting the discrete position as the unlocking position and judging the length of the touch when the user touches the unlocked position.
