Additionally, the display apparatus 100 may enlarge a selected sub-screen to a whole screen, based on the identification value of the key received from the remote controller 200. Hereinafter, this embodiment of the present disclosure is described in more detail with reference to drawings.
Referring to
The display apparatus 100 may divide a whole screen into the plurality of the sub-screens, based on a user input. The number and arrangement of the sub-screens obtained by the dividing may be selected by a user.
Additionally, the display apparatus 100 may display an image on each sub-screen. For example, the display apparatus 100 may receive broadcasting data from various broadcasting channels, and output the broadcasting data to each sub-screen. Additionally, the display apparatus 100 may execute one application on one sub-screen. For example, the display apparatus 100 may execute a web browser application on one sub-screen.
In operation S220, the display apparatus 100 may display a first indicator indicating the first point 118, located at a boundary between the plurality of the sub-screens, on the screen.
If the display apparatus 100 enters a screen-editing mode for changing a display area of the plurality of the images, the display apparatus 100 may display a user interface for changing the display area of the plurality of the images.
If the display apparatus 100 receives identification information of a key (e.g., screen-editing mode key 210) for entering the screen-editing mode from the remote controller 200, the display apparatus 100 may enter the screen-editing mode. If the display apparatus 100 receives a user input of selecting a screen-editing menu displayed on a screen, the display apparatus 100 may also enter the screen-editing mode.
If the display apparatus 100 enters the screen-editing mode, the display apparatus 100 may determine the first point 118, according to a state where a screen is divided at a point of time when the display apparatus 100 enters the screen-editing mode. In the display apparatus 100, a method of determining the first point 118 according to a state where a screen is divided may be preset. For example, if the whole screen is divided into 4 sub-screens, the first point 118 may be a point at which boundaries of the 4 sub-screens cross each other. If the whole screen is divided into 2 sub-screens, the first point 118 may be a center point of a boundary at which two sub-screens contact each other. The first point 118 may also be located at a crossing point at which boundaries of the plurality of the sub-screens cross each other, a center point of a boundary at which a plurality of sub-screens contact each other, or a corner of a sub-screen, but a location of the first point 118 is not limited thereto.
As the first point 118 is selected, the display apparatus 100 may display the first indicator on a location of the first point 118. A shape of the first indicator may be preset for the display apparatus 100. For example, the first indicator indicating the first point 118 may be a figure in the shape of a point. Additionally, the first indicator may be a preset number or one of respective identification values of keys on the remote controller 200, but is not limited thereto.
In operation S230, the display apparatus 100 may display second indicators on the plurality of the second points 110, 112, 114, 116, 120, 122, 124, and 126, which are different from the first point 118.
The plurality of the second points 110, 112, 114, 116, 120, 122, 124, and 126 may refer to points to which the first point 118 is to be moved based on a user selection.
If the display apparatus 100 enters the screen-editing mode, the display apparatus 100 may determine the plurality of the second points 110, 112, 114, 116, 120, 122, 124, and 126, according to a state where a screen is divided at a point of time when the display apparatus 100 enters the screen-editing mode. In the display apparatus 100, a method of determining the plurality of the second points 110, 112, 114, 116, 120, 122, 124, and 126 according to a state where the screen is divided may be preset. For example, the plurality of the second points 110, 112, 114, 116, 120, 122, 124, and 126 may be a center point of each sub-screen or a center point of boundaries at which 2 sub-screens contact each other.
The display apparatus 100 may display the second indicators at a location of the plurality of the determined second points 110, 112, 114, 116, 120, 122, 124, and 126. In this case, the display apparatus 100 may display the second indicators to be distinguished from the first indicator. The second indicators may be figures in the form of a point. Alternatively, the second indicators may be preset numbers that are different from each other or an identification value of keys on the remote controller 200 which are different from each other. In this case, the second indicators may be displayed in a same array as an array of keys on the remote controller 200.
In operation S240, the display apparatus 100 may receive an input of selecting one of the second indicators.
For example, if the second indicators are formed of a plurality of numbers which are different from each other, the display apparatus 100 may receive an input of selecting one of the plurality of the numbers.
In operation S250, based on the received input, the display apparatus 100 may move a boundary at which the first point 118 is located, so that the first point 118 is located at a second point corresponding to the selected second indicator.
The display apparatus 100 may determine a type of the received input. The type of the received input may refer to a method of pushing a key, which is performed by a user.
For example, the type of the input may include a click, a double click, or a long click, but is not limited thereto. Additionally, the type of the input may vary according to characteristics of the remote controller 200.
If the type of the received input is a first input, for example, a click, the display apparatus 100 may move a boundary of a sub-screen, at which the first point 118 is located, to pass a second point at which the selected second indicator is located. As the boundary of the sub-screen at which the first point 118 is located is moved, the first point 118 may be moved to the second point.
Additionally, the display apparatus 100 may adjust a size of an image displayed on the sub-screen, based on the moved boundary of the sub-screen. For example, the display apparatus 100 may change a size of an image displayed on a sub-screen, according to a rate at which the size of the sub-screen is changed. Additionally, for example, if an image is displayed on a whole sub-screen, the display apparatus 100 may adjust a size of the image so that a boundary of the image matches a boundary of the sub-screen.
Additionally, as the first point is moved, the display apparatus 100 may move the plurality of the second points so that the first point 118 is located at a center of the plurality of the second points. Additionally, the display apparatus 100 may display the second indicators on the plurality of the second points.
If a type of the received input is a second input, for example, a double click, the display apparatus 100 may determine whether a second point corresponding to the second indicator selected by a user are located at the boundary of the plurality of the sub-screens.
If the second point corresponding to the second indicator selected by a user is located at the boundary of the plurality of the sub-screens, the display apparatus 100 may exchange images on sub-screens, which are differentiated from each other according to the boundary at which the second point is located, with each other.
Additionally, if the second point corresponding to the second indicator selected by the user is not located at the boundary of the plurality of the sub-screens, the display apparatus 100 may enlarge the sub-screen, on which the second point is located, to a whole screen of the display apparatus 100. For example, if the second point corresponding to the second indicator selected by the user is located on one of the plurality of the sub-screens, the sub-screen on which the second point is located may be enlarged to the whole screen of the display apparatus 100. Additionally, the display apparatus 100 may receive an input corresponding to the first indicator. As the display apparatus 100 receives an input corresponding to the first indicator, the display apparatus 100 may determine a type of the received input.
If a type of the received input is determined as a first input, the display apparatus 100 may deactivate the screen-editing mode. As the screen-editing mode is deactivated, the display apparatus 100 may delete the first indicator and the second indicators which are displayed on the screen.
If a type of the received input is determined as a second input, the display apparatus 100 may adjust a size of the plurality of the sub-screens so that each size of the plurality of the sub-screens is identical to each other.
