Abstract: An electronic device and a system including the same are disclosed. The electronic device according to one embodiment of the present disclosure comprises a display; a memory that stores a usage history; a user input interface that transmits signals corresponding to user inputs; and a controller, wherein the controller checks the user account corresponding to a voice signal when the voice signal is received through the user input interface, determines whether the usage history for the user account is stored in the memory, outputs a preset first recommended query through the display when the user account does not exist or the usage history for the user account does not exists in the memory, and outputs a second recommended query corresponding to the usage history for the user account through the display when the usage history for the user account is stored in the memory.

Abstract: One embodiment of the present disclosure provides a display device comprising: a display including a display area for outputting content; a memory for storing at least one piece of data; a motor for controlling a partial area of the display area so as to be exposed; and a control unit for controlling the display, the memory, and the motor. The control unit: in a state in which only the partial area of the display area is exposed, outputs the content on a first area of the partial area; in a state in which the content is output on the first area, receives a first control signal; and outputs an OSD menu on at least one of the first area and a second area of the partial area.
