Is a setting for adjusting the volume level of the screen, and the screen state setting 110 is for selecting whether to output the display unit 22 when a TV-on operation occurs by setting the power state 106 to on. This item is for

The reason why the user uses the anti-theft function is to prevent theft, such as when the user is away from the house for a long time or falls asleep and cannot know the intrusion from the outside. In order to execute the on / off operation of the TV power supply, since there is no need for the output of the display unit 22 during the day, the screen state 110 may be set to save energy.

When the user sets a condition for executing the anti-theft function desired by the user mode, the controller 34 sets the time 104, the power 106, the volume 108, and the screen set by the user. 110, the setting information is stored in the storage unit 32.

Thus, when the user turns on the anti-theft function, the controller 34 controls the operation to be performed at the corresponding time based on the setting information stored in the storage unit 32.

That is, all 15 kinds of conditions set by the user are set. Therefore, the controller 34 extracts information of the first condition (Index0) to the fifteenth condition (Index14) based on the information stored in the storage unit 32, checks the information that matches the current time, and Control the operation to be done in time.

In the control method of the image display device having the anti-theft function according to the present invention configured as described above, the method for setting information of the anti-theft function desired by the user first determines whether the user inputs a power-on command (S202).

Subsequently, the determination result (S202), when the user inputs a power-on command to display the received image (S204).

In operation S206, it is determined whether the user wants to set a user mode for using the anti-theft function.

Subsequently, if the user wants to set a user mode, the determination result (S206) displays a screen for setting a condition desired by the user (S208).

The user sets a desired time, power on / off state, volume, and screen state through the displayed screen (S210).

Next, it is determined whether the user has completed the user mode setting (S212).

As a result of the determination (S212), if the user mode setting is completed, the information set by the user is stored (S214).

When the user inputs the power off command, the process ends. Otherwise, the process returns to the step S204 (S216).

In addition, the determination result (S206), if the user does not want to set the user mode enters to the step (S216).

In the control method of the image display device having the anti-theft function according to the embodiment of the present invention set as described above, in the control method of the image display device having the storage unit 32, first enters every minute to check the current time (S202).

That is, the anti-theft setting conditions of the image display device having an anti-theft function according to an embodiment of the present invention has a total of 15 setting conditions, and among these, the first setting condition is specified. The first setting condition is Index0.

Then, the set value corresponding to the condition (the set value corresponding to the Index th condition) is extracted (S208). That is, time, power state, volume, and screen state information set by the Index-th user are extracted based on the information stored in the storage unit 32.

Subsequently, it is determined whether or not the time condition of the extracted set value coincides with the current time (S210).

When the time condition of the extracted setting value and the current time coincide with the determination result (S210), the volume, power state, and power state corresponding to the setting value are applied (S212).

Then, the process proceeds to the next set value (S214). That is, the next index of the index previously performed by the user is designated. In other words, do Index + 1.

Subsequently, it is determined whether the corresponding Index is smaller than the Max index (S216). That is, the condition for setting the anti-theft function by the user according to an embodiment of the present invention includes a total of 15 conditions. Therefore, it is determined whether it is smaller than the current index and the max index (Index14).

If the current index is smaller than the max index (S216), the process returns to the step S208.

In addition, if the current index is greater than the max index (S216), the process returns to the step S202.

 In addition, the determination result (S204) if the user does not turn on the anti-theft function is terminated.
