Hereinafter, with reference to FIG. 1 to FIG. 12, a process of setting a screen lock function by the terminal device 100 according to an embodiment of the present invention and a process of releasing the screen lock state by the user in such a screen lock state will be described in detail Let's take a look.

First, the process of setting the screen lock function by the user of the terminal device 100 will be described.

The user of the terminal device 100 operates the predetermined button or the like to use the screen lock function according to the embodiment of the present invention. Then, the controller 170 senses this and controls the display unit 141 of the output unit 140. The display unit 141 displays the screen lock detail setting menu under the control of the controller 170 (S201, S203) .

Then, the user can select a desired menu from the screen lock detailed setting menu. If the selection of the screen lock detailed setting menu by the user is sensed by the sensing unit 142, the controller 170 stores the selected screen lock detailed setting value (S201, S203).

Here, the user of the terminal device 100 can select the shape of the screen lock icon, the security level, the unlocking difficulty, the icon rearrangement period, the icon rearrangement motion, and the icon arrangement method (S205).

For example, the shape of the screen lock icon can be selected from a symbol icon, a picture icon, and the like, and it is possible to select the shape of the icon included in the lock screen. The security level and unlocking difficulty can be adjusted by selecting the number or size of the icons included in the lock screen. This is because the unlocking difficulty increases as the number of icons included in the lock screen increases. Also, it is possible to adjust the unlocking degree of difficulty by selecting whether to apply the touch order of the icons. The icon rearrangement period is to set the screen refresh period to change the position of the icon or replace the icon. Icon rearrangement motion is to set which motion the user will take when rearranging the icon. In addition, the icon arrangement method sets whether the icons are arranged in a row in the vertical and horizontal directions or randomly and freely.

Next, the control unit 170 stores the selected screen lock detailed setting value when the screen lock detailed setting menu is selected (S207), and displays the lock screen, which can input and register the unlock information based on the stored screen lock detailed setting value A setting window is displayed (S209). Here, the lock screen setting window includes a symbol icon or a picture icon according to the screen lock detailed setting value stored in step S207, and the number and size of the icons included are determined according to the security level and the unlocking difficulty.

As such, when a lock screen setting window including a symbol icon or a photo icon is displayed, the user touches at least one of the icons to input the unlock information to be used by the user. If it is determined in step 205 that the touch sequence of the icons is selected as the screen lock detailed setting value, the plurality of icons must be touched in the correct order in accordance with the order to be used in the touch operation.

Then, the touch operation of the lock screen setting window is sensed by the sensing unit 142, and the controller 170 stores the corresponding display area information in which the touch operation is sensed, as the unlock information (S211, S213). Here, the lock screen setting window includes a plurality of icons, and the user can touch and manipulate at least one of the plurality of icons to store the unlock information. Steps S209 and S213 can be adopted as the unlocking information only when the detected display area information is repeatedly performed at least two times or more. Also, when a plurality of unlocking modes are operated, a plurality of unlocking information corresponding thereto can be stored.

In addition, if a plurality of unlocking modes are operated, the unlocking information should also be input correspondingly. For example, if it is desired to operate a plurality of unlocking modes by changing the number of icons to be touched, steps S209 to S213 may be repeatedly performed by changing the number of icons to be touched.

Thereafter, the display unit 141 displays the user authentication setting window (S215), the sensing unit 142 senses the touch operation on the user authentication setting window (S217), and the control unit 170 displays the user authentication Information is stored (S219). Here, the user authentication information is received in case of forgetting the unlock information to be inputted through the touch operation in step S211, and can be used to authenticate whether the user is a normal user at the time of initializing the unlock information.

The process of setting the screen lock function by the user of the terminal device 100 has been described. Now, the process of releasing the screen lock state of the terminal device 100 by the user with the screen lock function being set will be described.

In the screen locked state, the display unit 141 displays a lock screen including a plurality of icons. Here, the shape and number of the icons displayed on the lock screen are determined by the screen lock detailed setting values stored in step S207 (S301). For example, a lock screen including a symbol icon may be displayed as shown in FIG. 7A, and a lock screen including a picture icon may be displayed as shown in FIGS. 8A, 9A, and 10A.

If the user touches the lock screen, the sensing unit 142 senses the touch operation (S303), and the controller 170 loads the stored unlock information in operation S303 (S305).

Next, the controller 170 selectively maintains or releases the screen lock state according to a result of comparison between the display area information in which the touch operation is detected and the preset lock release information. 3 illustrates a case where a plurality of unlocking modes are operated.

At this time, the control unit 170 determines any one of the plurality of unlocking modes selected according to the comparison result between the display area information in which the touch operation is detected and the predetermined unlocking information. That is, it is determined whether the unlock information corresponding to the unlock mode 1 is input or the unlock information corresponding to the unlock mode 2 is input (S307, S309, S311). If it is determined in step 205 that the touch sequence of the icon is applied as the screen lock detailed setting value, the touch order of the icons that can be extracted from the display area information in which the touch operation is detected is the order of the icons It can be determined that the unlocking information has been input correctly only if it matches the touch sequence.

Then, the control unit 170 controls the display unit 141 according to the determination result of the unlocking mode, and the display unit 141 displays any unlocking mode corresponding to the unlocking mode determined in the predetermined plurality of unlocking screens The screen is displayed or the screen lock state is maintained (S313, S315, S317). For example, in the unlock mode 1, an initial screen of the unlock screen 1 as shown in FIG. 10B can be displayed. In the unlock mode 2, an initial screen of the unlock screen 2 as shown in FIG. 10C can be displayed. 10B and 10C, it can be seen that the number or arrangement of application program icons 703 is different. That is, the user can select the unlock mode and immediately use the initial screen displayed with the frequently used application icon 703.

In addition, the control unit 170 extracts the number of touch-operated icons from the plurality of icons from the display area information in which the touch operation is detected by the sensing unit 142, and selects a plurality of unlocking modes The unlocking mode may be determined.

Here, if the start application selection information is stored in the screen lock detailed setting value stored and set in step S207, if the screen lock state is released in step S313 or step S315, since the predetermined start application program is automatically executed, ), The execution screen of the application program can be displayed.

On the other hand, the release of the screen lock state of the terminal device 100 may be automatically performed by the terminal device 100 in addition to the manual operation by the user. That is, the terminal device 100 automatically releases the screen lock state within a specific area.

To this end, in a state in which the display unit 141 displays a lock screen, the short range communication unit 112 of the communication unit 110 searches for an access point supporting connection to the communication network, and transmits the identification information of the searched access point to the control unit 170 (S501, S503).

Then, the controller 170 selectively maintains or cancels the screen lock state according to the comparison result between the identification information of the searched access point and the predetermined unlocking identification information (S505, S507, S509). In this way, the identification information of the access point for automatically releasing the screen locking state can be set through step 207. When the terminal device 100 connects to the predetermined access point, the control section 170 automatically releases the screen locking state can do.

Next, a process for updating the screen according to the screen lock detailed setting value set in step S207 will be described.

The display unit 141 displays a lock screen including a plurality of icons, and the control unit 170 determines whether or not the screen update condition preset by the screen lock detailed setting value stored in step S207 is satisfied (S401, S403 ). For example, the screen update condition may be at least one of a predetermined period, a failure count of a release attempt for a predetermined motion detection or a screen lock state, and the like.

Here, when the predetermined screen update condition is satisfied, the controller 170 controls the display unit 141 to randomly change the display position of the icon in the lock screen, or change some icons among the plurality of icons to different icons, (S405). For example, when the predetermined period has elapsed in the initial screen in which the icon of FIG. 7A is fixedly arranged, the display position of the icon may be randomly changed as shown in FIG. 7B. Alternatively, when a predetermined period has elapsed in the initial screen in which the icon of FIG. 8A is freely arranged, some of the plurality of icons may be changed to another icon as shown in FIG. 8B. Here, in the case of the icon included in the unlock information stored in step S213, only the display position is changed without disappearing from the screen. 7B, when the number of unsuccessful attempts to release the screen lock state exceeds the preset reference number as in step S317, the display position of the icon may be changed again at random as shown in FIG. 7C.

In addition, the terminal device 100 may change the icon array mode according to the user's selection while displaying the lock screen according to the screen lock detailed setting value set in step S207.

The display unit 141 displays a lock screen including a plurality of icons according to the screen lock detailed setting value set in step S207 (S601). Here, the icons are arranged freely or fixedly in the lock screen according to the preset screen lock detailed setting values. For example, when the current setting state is a free arrangement, a fixed arrangement selection button 705 arranged as illustrated in FIG. 11A and capable of changing to a fixed arrangement is displayed together. When the current setting state is a fixed arrangement, a free arrangement selection button 707 arranged as illustrated in FIG. 11B and capable of being changed into a free arrangement is displayed together.

In this state of the lock screen, the sensing unit 142 senses the selection information of the arrangement mode for the icon, and provides the sensed information to the controller 170. For example, a touch operation to the fixed array selection button 705 of FIG. 11A or the free array selection button 707 of FIG. 11B is sensed (S603).

Then, the control unit 170 changes the icon arrangement mode in the lock screen according to the detected icon arrangement mode selection information (S605), controls the display unit 141 to display the updated lock screen, 141) displays an update lock screen in which the icon arrangement method is changed (S607).
