Abstract: A method for changing a play mode for a three-dimensional (3D) image includes receiving state information regarding shutter glasses from the shutter glasses; generating a graphic user interface (GUI) corresponding to the state information; and displaying the GUI corresponding to the state information, wherein the changing a play mode is performed according to a user input to change the play mode received through the GUI.

Abstract: A play mode changing method, a display mode changing method, and a display apparatus and a three-dimensional (3D) image providing system using the same are provided. The method for changing a play mode includes: receiving state information regarding shutter glasses from the shutter glasses; and based on the received state information, performing one of changing the play mode and displaying a message for changing the play mode.

Abstract: A three-dimensional (3D) image providing method and a display apparatus using the same are provided. According to the 3D image providing method, if a particular manipulation is input from a user in the two-dimensional (2D) mode, whether an input image is a 2D image or a 3D image is detected. If the input image is the 3D image, the display mode is changed to the 3D mode and the 3D image is displayed. If the input image is the 2D image, the input 2D image is converted to a 3D image and the converted 3D image is displayed by changing the display mode to the 3D mode. Thus, regardless of whether the input image is the 2D image or the 3D image, users can execute the 3D mode using the single manipulation.

Abstract: A display apparatus includes a display configured to display a thumbnail image that indicates a corresponding content group; a user interface configured to receive a user command; and a controller configured to control the display to successively display thumbnails that represent a plurality of pieces of content belonging to the corresponding content group, when a graphical user interface (GUI) is positioned on the thumbnail image.

Abstract: A method of setting a function and a display apparatus applying the same are provided. The method of setting a function of the display apparatus includes displaying a set item list, which includes one or more set items, on a screen of the display apparatus; and in response to a set item on the set item list being selected, providing a menu for accessing one or more other set items associated with the selected set item.

Abstract: A method of providing a three-dimensional (3D) image and a 3D display apparatus applying the same are provided. If a predetermined instruction is input in 2D mode, display mode is changed to 3D mode. A predetermined format is applied to an incoming image, and the resultant image is displayed in 3D mode. If the predetermined instruction is input again in 3D mode, another format is applied to the incoming image and the resultant image is displayed. As a result, a viewer can conveniently select a 3D image format of the incoming image.

Abstract: A play mode changing method, a display mode changing method, and a display apparatus and a three-dimensional (3D) image providing system using the same are provided. The method for changing a play mode includes: receiving state information regarding shutter glasses from the shutter glasses; and based on the received state information, performing one of changing the play mode and displaying a message for changing the play mode.

Abstract: A graphical user interface (GUI) providing method, a display apparatus and a three-dimensional (3D) image providing system using the same are provided. The GUI providing method includes: generating a first GUI for changing settings for a 3D image and a second GUI for changing an environment; and outputting the first GUI and the second GUI. Thus, the settings for the 3D image can be changed more easily and conveniently.

Abstract: An apparatus and method which display a three dimensional (3D) video signal, the apparatus comprising: a receiver which receives a video signal; a video signal processor which processes the received video signal; a display unit which displays thereon the processed video signal; and a controller which, in response to the received video signal being a 3D video signal, controls the video signal processor to convert the received 3D video signal into a two dimensional (2D) video signal, and displays the 2D video signal on the display unit.

Abstract: A method for providing program information and a display apparatus using the same are provided. A method for providing program information includes extracting program information based on a finish time of a program, and generating and displaying a program information screen based on the extracted program information. Accordingly, since program information which the user actually needs is selectively provided, the user may view a program information screen with greater view stability.

Abstract: Provided are a method and display apparatus for providing a graphical user interface (GUI), the method includes: receiving program information; dividing the program information into a first main group having a first set of items of program information, and a second main group having a second set of items of program information, wherein the dividing is performed according to a property, and each of the first and second main groups corresponds to a unique value of the property; if a number of items in the first main group together with a number of items in the second main group is less than or equal to a maximum number, grouping the first set of items and the second set of items together into a sub-group; and displaying the GUI including at least one item of program information from the sub-group.
