Abstract

An apparatus and method for automatically controlling screens displayed on two display units installed in a mobile terminal are provided, in which, an event is identified, if an event occurs, and on and off states of the display units are controlled, if the event is identified as a control operation of the display units corresponding to a user'"'"'s key input. If the event is identified as a control operation of the display units corresponding to an operation of a sensor, the display units are automatically controlled corresponding to rotation of the mobile terminal.

Claims

1. A mobile information device comprising:

a body;

a first display on a first surface of the body;

a second display on a second surface opposite of the first surface;

an input portion;

a sensor configured to sense a movement of the body; and

a processor configured to control at least one of the first display and the second display based on the sensed movement such that an operation state of the at least one of the first display and the second display is changed;

wherein the operation state comprises on/off states of the first and/or second display based on the sensed movement.

2. A mobile information device comprising:

a body;

a first display on a first surface of the body;

a second display on a second surface opposite of the first surface;

an input portion;

a sensor configured to sense a movement of the body; and

a processor configured to control at least one of the first display and the second display based on the sensed movement such that an operation state of the at least one of the first display and the second display is changed and the second display has functionality different from that of the first display based on the sensed movement.
