When the electronic device 100 is idle for a certain period of time or is operated to enter the screen lock state, the processing module 120 generates a protection interface to cover and lock the original use interface displayed by the touch screen 110.

Please refer to FIG. 2, which is a flowchart of a first embodiment of the method for unlocking the screen of the present invention. It should be noted that although the electronic device 100 shown in FIG. 1 is taken as an example to illustrate the method for unlocking the screen of the present invention, the present invention is not limited to the application of the electronic device 100, and any other electronic device having a similar structure is also The method of the invention can be applied. As shown in FIG. 2, the method for unlocking the screen of the present invention includes steps S201 to S204. The various steps of the method are described in detail below.

Step S201: displaying a complex pattern in the protection interface A1.

Please refer to FIG. 3(a), FIG. 3(b), FIG. 3(c) and FIG. 3(d) together. 3(a) is a schematic diagram showing the original use interface A0 in the normal use state; FIG. 3(b) is a schematic view showing the electronic interface 100 displaying the protection interface A1 in the screen locked state; FIG. 3(c) is an application. The screen unlocking method of the present invention displays a schematic diagram of the complex pattern 10 in the protection interface A1; and FIG. 3(d) is a schematic diagram of forming the combined pattern 20 in the protection interface A1 by applying the screen locking method of the present invention.

As shown in FIG. 3( a ), the electronic device 100 is displayed on the touch screen 110 in the normal use state to display the currently used operating system or the original application interface A0 of the executed application (for example, a system desktop or an application). Interface, etc., for the user to respond to touch operations.

As shown in FIG. 3(b), when the electronic device 100 enters the screen lock state, the processing module generates a protection interface A1 and displays it through the touch screen 110 to cover and lock the original use in FIG. 3(a). The interface A0 prevents the touch screen 110 from being unintentionally touched. The protection interface A1 uses a picture, a transparent or non-transparent background interface to cover the original interface.

As shown in FIG. 3(c), after the electronic device 100 enters the screen lock state, when the user performs touch input on the touch screen 110, that is, the touch screen 110 receives the touch signal, the touch screen 110 is touched at this time. A plurality of patterns 10 are displayed on the protection interface A1, and each pattern 10 is a geometric shape, such as a polygon or a circle. The number and shape (or/or size) of the patterns 10 are set according to the application. Or displayed in random numbers, but the invention is not limited thereto. The plurality of patterns 10 displayed on the protection interface A1 will at least include the necessary pattern for unlocking.

Step S202: Receive at least one touch operation to combine at least two of the plurality of patterns 10 into a combined pattern.

As shown in FIG. 3(c), in a state where the protection interface A1 displays the plural pattern 10, the user can perform any touch operation on the patterns 10. After receiving the at least one touch operation input by the user, the touch screen 110 determines that the corresponding command is executed by the processing module to perform operations such as moving or rotating the protection interface A1 for the patterns 10, or These patterns 10 perform operations such as zooming in or out. Therefore, the user can move or rotate any of the patterns 10 by the touch operation to combine with the other pattern 10, so that at least two of the plurality of patterns 10 can be combined into a combined pattern 20 of any form, as shown in FIG. (d) is shown. The processing module is based on the combined pattern 20 as a screen to be compared. In an embodiment of the present invention, the user can delete or discard the redundant pattern in the protection interface A1 by using a touch operation, such as clicking a pattern and sliding toward the edge of the touch screen 110, but not This embodiment is limited.

In addition, in this embodiment, step S202a may be further included after step S202: receiving a rotation operation to rotate the combined pattern.

After the complex pattern is combined to form a combined pattern, the touch screen 110 can still be rotated for the combined pattern by the rotation operation input by the user. Since the combined pattern will have different appearances or changes in the relative position of the constituent patterns after rotation, it will affect the subsequent comparison results, and the design can provide more diverse combinations of pattern changes.

Step S203: Determine whether the combined pattern conforms to the unlock pattern stored in the database.

After the touch operation of the step S202 or the step S202 is performed, the user selects the button A12 on the protection interface A1 or inputs the corresponding determination command, or the touch screen 110 detects that the touch point has disappeared. The processing module 120 starts to obtain related information according to the combined pattern completed on the current protection interface A1, and compares with the unlock pattern stored in the database in advance to determine whether the two match.

Please refer to Figure 4(a) and Figure 4(b) together. 4(a) is a schematic view showing the first embodiment of the method for unlocking the screen of the present invention, wherein the combination pattern 20 conforms to the unlock pattern 30; and FIG. 4(b) is a first embodiment of the method for releasing the screen lock according to the present invention. The combined pattern 20a does not conform to the schematic of the unlock pattern 30.

As shown in FIG. 4(a), in the embodiment, the processing module extracts its shape code according to the currently completed combination pattern 20, and compares it with the external pattern of the unlock pattern 30, and combines the pattern 20 and unlocks. The outer shape of the pattern 30 is shown by a thick line as depicted in the figure; when the shape codes are identical, the combination pattern 20 corresponds to the unlock pattern 30, and the step S204 is continued. Conversely, as shown in FIG. 4(b), if the processing module determines that the combined pattern 20a and the unlock pattern 30 are different from each other, the combined pattern 20a is determined to be invalid, and the screen lock state is continuously maintained. When the foregoing determination combination pattern 20a does not match the unlock pattern 30, the touch screen 110 or the electronic device 100 itself may send a prompt message (such as image or sound, etc.), return to step S202, and reset the patterns for the user. Re-operation, but the invention is not limited thereto.

Please refer to FIG. 5(a), FIG. 5(b), FIG. 5(c) and FIG. 5(d) together. Figure 5 (a) is a schematic view showing the second embodiment of the method for unlocking the screen of the present invention, wherein the combination pattern is in accordance with the unlock pattern; Figure 5 (b), Figure 5 (c) and Figure 5 (d) are applied to the present invention. The second embodiment of the method for unlocking the screen determines that the combined pattern does not conform to the schematic of the unlock pattern.

As shown in FIG. 5( a ), in the embodiment, the protection interface A1 is divided into a plurality of blocks of the same size and regularly arranged in a plurality of longitudinal and lateral straight lines, and the sizes of the patterns to be combined are at least correspondingly occupied. 1 block. A code is defined for each of the different shapes of the pattern, and the block position occupied by the pattern is represented by its corresponding code. For example, in this embodiment, the protection interface A1 is divided into 8×6 blocks, and the code of the square pattern is assumed to be 0, the code of the rectangular pattern is 1, and the code of the circular pattern is 2; in the combination pattern 20b The position of the block occupying the square pattern of one block size is represented by code 0, and the position of each block occupying the rectangular pattern of three block sizes is represented by code 1, and is circular in the size of one block. The block position of the pattern is indicated by code 2.

Thereafter, the processing module 120 sequentially scans all the complex blocks in a row-by-row or column-by-column manner, so that the code sequence corresponding to the combined pattern 20b can be obtained. Taking the progressive (portrait) scan as an example, after scanning from left to right in the direction of the arrow in FIG. 5(a), the obtained code sequence is 0-111-2, and the code sequence and the unlock pattern are obtained at this time. The corresponding unlocking code sequences (for example, shown in parentheses in the figure) are compared with each other. After confirming that both are 0-111-2, it can be determined that the combined pattern 20b conforms to the unlocking pattern, and the step S204 is continued.

Conversely, as shown in FIG. 5(b), if the circular pattern in the combined pattern 20c is replaced by a square pattern, the code sequence is converted to 0-111-0, which is different from the unlocking code sequence 0-11 of the unlock pattern. -2, so the processing module will judge that the combined pattern 20c does not match the code sequence of the unlock pattern and continues to maintain the screen lock state. As shown in FIG. 5(c), when the circular pattern in the combined pattern 20d is resized, although the right side of the combined pattern 20d is a circular pattern, the code sequence is converted to 0-11-22-22-22. It is also different from the unlock code sequence 0-111-2 of the unlock pattern, so the processing module still judges that the combined pattern 20d does not match the code sequence of the unlock pattern, and continues to maintain the screen lock state. It should be noted that the interface division mode, the pattern code definition manner, or the scanning mode used in the embodiment is only one of the implementation manners, and the system is changed according to the device or the program design, and the present invention does not limit.

In addition, as shown in FIG. 5(d), when the combined pattern 20e is subjected to the rotating operation, the relative positions of the patterns constituting the combined pattern 20e also change, which will affect the unlocking comparison result. After the combination pattern 20e is rotated by 90 degrees, the code sequence corresponding to the combination pattern 20e is changed to 12-1-01, which is different from the unlock code sequence 0-111-2 of the unlock pattern, so the processing module judges The combined pattern 20e does not match the code sequence of the unlock pattern and continues to remain in the screen lock state.

Step S204: Remove the protection interface A1 to release the screen lock state.

When the processing module 120 determines that the combination pattern and the unlock pattern match each other, the condition for releasing the screen lock is reached. Therefore, the processing module 120 is removed from the protection interface A1 displayed on the touch screen 110, and the original interface A0 is displayed. That is, returning to the state shown in FIG. 3(a) to release the screen lock state for the user to use normally.

By the method for unlocking the screen of the present invention, the pattern unlocking method is used to achieve the screen unlocking effect, which can provide higher security and bring different operating feelings to the user.

Please refer to FIG. 7( a ) which is a schematic diagram showing the setting interface A2 of the electronic device 100 .

As shown in FIG. 7(a), when the processing module 120 receives the command input by the user, the application program executes the command to generate a setting interface A2, and displays the setting interface A2 through the touch screen 110. . The setting interface A2 is used for the user to set the unlocking pattern. In the embodiment, the setting interface A2 includes the setting pattern tool column A21, so that the user can select each setting pattern required to form the unlocking pattern, but the present invention does not Limited.

Step S206: Display a plurality of setting patterns constituting the unlock pattern in the setting interface A2.

Please refer to FIG. 7(b), which is a schematic diagram of displaying a complex setting pattern by setting interface A2.

As shown in FIG. 7(b), the user selects each setting pattern to be combined by setting the setting tool row A21 of the interface A2, and the processing module corresponds to the display interface A2 having the required number and shape. The plural setting pattern 40. Each of the setting patterns 40 is also a geometric shape such as a polygon or a circle.

Step S207: Receive at least one touch operation to combine the plurality of setting patterns as the unlocking pattern.

Please refer to FIG. 7(c), which is a schematic diagram of setting a pattern by using the setting interface A2 to unlock the pattern.

As shown in FIG. 7(c), at least one touch operation of the user is received by the touch screen 110, and the processing module executes corresponding commands to select, move or rotate the setting patterns, and the settings can be adjusted. The size of the pattern allows the complex setting pattern to be combined into the desired unlock pattern 30a in any form.

Step S208: storing the unlock pattern in the database and leaving the setting interface A2.

As shown in FIG. 7(c), after the combination of the unlock pattern 30a is completed in the foregoing step, after the storage determination is performed by setting the interface A2 (for example, the user presses the button A22 on the setting interface A2 or inputs the corresponding storage instruction). The processing module stores the comparison pattern of the unlock pattern 30a in the database as the screen unlocking standard, and is used to compare with the combined pattern input by the user in the subsequent steps.
