Abstract: A door assembly is used for a refrigerator and a home appliance. The door assembly includes a door body, and a lighting panel coupled to a front surface of the door body. The lighting panel includes a panel frame with a coupling space, and a lighting device is installed to the panel frame. A light guide panel is arranged in the coupling space. A front panel is arranged on a front surface of the lighting panel in parallel to the light guide panel. A diffusion panel is arranged between the front panel and the light guide panel. Therefore, a user can change a color of a door surface by the lighting device without replacing a door panel, and the diffusion panel diffuses light once to make the light uniform.

Abstract: A DTV and a method of displaying content using the same are provided. The DTV includes: a plurality of display units physically isolated from each other; and a control unit configured to, if a predetermined first event has occurred, move a content displayed on the first display unit among the plurality of display units and display the content on the second display unit among the plurality of display units, wherein the control unit is configured to control the display of the content such that the movement process of the content is visually recognized.

Abstract: A mobile terminal and method of reducing power consumption in the mobile terminal are provided. The method includes displaying an operation screen in the first display module, determining a remaining battery power of the mobile terminal, and disabling the first display module and displaying the operation screen in the second display module in response to determining that the remaining battery power is less than a reference battery power.

Abstract: A DTV and a method of displaying content using the same are provided. a DTV includes: a plurality of first and second display units physically isolated from each other; a communication unit configured to communicate with an external remote control; and a control unit configured to move a content between the first and second display units in response to a motion of the remote control sensed by a signal received from the remote control through the communication unit.

Abstract: A mobile terminal and a method of controlling the operation of the mobile terminal are provided. The method includes displaying a screen image including one or more objects on a first display unit, and if one of the objects is touched and then dragged, displaying the touched-and-dragged object on the second display unit. Therefore, it is possible to continuously display an object even in the event of a power cut by quickly moving the object from the first display unit to the second display unit.

Abstract: Provided is a method of controlling the operation of a mobile terminal equipped with first and second display modules provided on first and second surfaces, respectively, of a main body of the mobile terminal. The method includes choosing an operation menu; displaying a first image corresponding to the chosen operation menu on a first display module; and displaying a second image corresponding to the chosen operation menu on a second display module. Therefore, it is possible to effectively control the operation of the mobile terminal using the first and second display modules.
