The related application information may include information about other applications related to the selected application. Thus, the user can select the relevant application information tab (view related APP) on the displayed preview information to check the application list associated with the selected application.

Here, when the relevant application information tab is selected, the controller 170 may display a list of related applications in the same format as new preview information.

In addition, when any one of the displayed applications is selected, the controller 170 may display the preview information of the corresponding application again. Accordingly, a plurality of preview information may be displayed on one screen, and the user may easily grasp the preview information on the related application without searching for the application separately.

9 is a flowchart illustrating a method of operating an image display device according to another exemplary embodiment.

Referring to FIG. 9, the image display apparatus 100 displays icons for an application as described above, and one of them is selected by the user (S200).

In addition, the controller 170 of the image display apparatus 100 checks the position of the pointer 400 located around the selected icon (S210). The pointer 400 may move according to a control signal input through the communication unit 160 by the remote controller 200.

Thereafter, the controller 170 determines a position to display the preview information on the basis of the confirmed position of the pointer 400 and the position of the selected icon (S230), and displays the preview information on the determined position (S230).

Here, the preview information may be displayed at various locations for user convenience. For example, the preview information may be displayed at a position spaced apart from the pointer 400 by a predetermined distance or more, thereby providing an intuitive interface to the user. In addition, the controller 170 may determine the location of the pointer 400 to calculate a direction in which the pointer 400 approaches the application icon, and display preview information at a location corresponding thereto. In this case, the preview information may be flexibly displayed as the user moves the pointer 400.

Meanwhile, after the preview information is displayed, the controller 170 determines whether there is a movement of the pointer 400 again (S240). If the pointer 400 does not move or the movement is maintained within a predetermined distance, the controller 170 determines that there is no movement, and continuously displays the preview information.

 Then, when the movement of the pointer 400 is confirmed, the controller 170 determines whether the application selection is released (S250). The controller 170 may determine whether the application selection is released by determining whether the application is moved more than a predetermined distance from the corresponding application icon (S250). When the application selection is released, the controller 170 ends the display of the preview information. When the selection is maintained or when it is determined that another application is selected, the controller 170 returns to step S210 again and repeats the above-described process.

FIG. 11A illustrates first preview information of a first application selected according to a pointer.

Subsequently, FIG. 11B shows that the second preview information for the second application is displayed as the pointer moves around the second application icon. Here, the controller 170 may determine whether to display the preview information based on the time when the pointer is located. Therefore, when the pointer is over other application icons positioned in the middle within a predetermined time, the second preview information of the second application icon finally arrived. Only display is possible.

11 (c) and 11 (d) show that the first preview information, which has been deselected, is removed from the display using the fade out effect. This may provide a user with a more visually natural deselection effect of the preview information.
