4 is a flowchart illustrating a method of controlling an image display apparatus according to an exemplary embodiment of the present invention.

A method of controlling an image display apparatus according to an exemplary embodiment of the present invention includes displaying a first object on a display including information related to the executed function when a predetermined function is executed based on a user command S420); Displaying the second object on the display when the first object is displayed (S430); And changing a display state of the second object if the command related to the second object is not received for a predetermined time (S450).

The object includes various kinds of widgets displayed on the display 170 so as to be able to input commands to the image display apparatus 100 or display information related to the image display apparatus 100. [ The widget can be displayed as an OSD (On Screen Display).

The object includes an image or text representing information about the image displayed on the image display apparatus 100 or the image display apparatus 100, such as the sound output (volume) level of the image display apparatus 100, the channel information, do. The object may be displayed in the image display apparatus 100 or may be implemented in a different form (e.g., moving picture) according to the type of information to be displayed, and the object of the present embodiment does not limit the scope of the present invention.

In this embodiment, the object may be a widget. A widget is a graphical user interface (GUI) element that allows a user to directly change or execute specific data. For example, the widget may be one of a volume control button, a channel control button, a menu, an icon, a navigation tab, a scroll bar, a progress bar, a text box, and a window displayed on the display 170 of the image display apparatus 100. The type of the widget implemented in the image display apparatus 100 may be changed in accordance with the specific specification of the GUI that can be implemented or implemented in the image display apparatus 100 and the widget of the present embodiment does not limit the scope of rights of the present invention No.

In the case of a computer or a mobile communication terminal, there is no idle state or idle state in which a user does not execute any application, so that even if the object is displayed on the screen, the usability of the device is not greatly affected. Further, the object can be executed without inconvenience of the user. However, in the case of the video display device, the video is displayed in the idle state unless it is a special case such as a menu input screen. Therefore, in the case of a video display device in which a user has to provide information on an object and an image displayed on the idea that the user desires to view the information immediately, it is required that the display of the object does not interfere with the viewing of the video by the user. Here, the image may be a still image and a moving image.

Therefore, the control method of the video display device according to the present invention displays the object when the predetermined function is executed based on the user's command, and changes the display state of the object. When the user uses a predetermined function of the video display device, the concentration of the user's video is dispersed due to the execution of the function, so that the object frequently used by the user is displayed so that viewing of the video is not disturbed. Thereafter, the display state such as the transparency and the size of the displayed object is changed so that the viewing of the image of the user is not disturbed due to the object.

The predetermined function may be at least one of channel switching, volume control, and a reservation function for executing a reserved command at a specific time. When the user switches the channel or adjusts the volume, the first object for displaying the changed channel or the volume is displayed, and in this case, the second object is automatically displayed automatically. When switching a channel, the first object is a channel banner that includes not only the changed channel but also a broadcast name, a channel number, a program name, a start time, a current program progress bar, an end time, a category, .

Also, when the input mode is switched to the external input device, information informing the input mode may be similarly displayed.

In addition, when a function that the user desires to execute at a specific time is executed, such as a scheduled recording and a notification function, a first object including a message informing execution is displayed, and in this case, the second object can be automatically displayed have.

In the second object display state changing step S450, the controller 180 may gradually change the display state of the second object displayed on the display 170 to correspond to the passage of time.

For example, the transparency of the second object can be gradually increased. The transparency is gradually increased over time from the initial object transparency value in the step of displaying the second object on the display (S430), thereby preventing the object from obscuring the video.

It is also possible to gradually increase the transparency until the transparency reaches the predetermined value, to keep the predetermined value, or to gradually decrease the transparency when it reaches the predetermined value after gradually increasing the transparency to the predetermined value. In this case, the predetermined value may be a maximum value of transparency. In other words, the object may be displayed in a completely transparent state.

In another embodiment, the size of the second object may be gradually reduced, the size may gradually decrease until the size reaches a predetermined size, or the size may gradually decrease and then gradually increase. By progressively reducing the size of the object over time, the area in which the object is displayed on the display is reduced, thereby hiding the screen less. Also in this case, the predetermined size may be a state where the size is zero, and the object disappears.

In addition, the second object display state changing step S450 may change the display state of the object when a predetermined time elapses after the object is displayed. That is, instead of linearly changing the display state of the object, it is possible to discontinuously change the display state of the object when a predetermined time has elapsed after setting a predetermined time as a reference.

For example, in the second object display state change step S450, the controller 180 may change the size or shape of the object when the predetermined time has elapsed, and may cause the object to disappear. Further, it is possible to change the display state of the object every time a predetermined time elapses by setting a predetermined time as a reference.

The size of the object is reduced when the set time passes, thereby reducing the area in which the object is displayed on the display. Alternatively, the object may be changed to an icon or an icon representing the function of the object selected by the user.
