Claim Text:
1. A display device comprising: a display unit for displaying visual information to a user on an overall screen region, and being configured to bend with respect to a bending portion between screen regions of the overall screen region that display the visual information; a pressure sensor at a location corresponding to the bending portion, and being configured to sense a first pressure applied to the bending portion when the display unit is bent with respect to the bending portion; and a control unit for controlling the visual information provided through the display unit based on sensing information transferred from the pressure sensor, wherein when the display is bent such that a size of a first screen region at a side of the bending portion is different from that of a second screen region at an other side of the bending portion, the pressure sensor is configured to generate a first sensing signal corresponding to a bending angle of the display, the control unit is configured to receive the first sensing signal, to match the first sensing signal with data stored in a database of the control unit, and to transmit a first control signal to the display unit, and the display unit is configured to display different kinds of the visual information on the first screen region and the second screen region based on the first control signal, wherein when the display is unbent with respect to the bending portion, the pressure sensor is configured to generate a second sensing signal different from the first sensing signal and corresponding to the display being unbent, the control unit is configured to receive the second sensing signal, to match the second sensing signal with the data stored in the database of the control unit, and to transmit a second control signal to the display unit, and the display unit is configured to select visual information from the different kinds of the visual information displayed on the first and second screen regions based on the second control signal and to display the selected visual information on the overall screen region, and wherein when the display unit is bent with respect to the bending portion so that a first screen region and a second screen region among the screen regions of the display unit are substantially parallel to and not coplanar with each other, the pressure sensor is configured to generate a third signal different from the first and second sensing signals, the control unit is configured to receive the third signal, to match the third signal with the data stored in the database of the control unit, and to transmit a third control signal to the display unit, and the display unit is configured to turn off and to switch the display device to a lock mode based on the third control signal, wherein the pressure sensor comprises a capacitive-based pressure sensor.
