a display unit configured to be combined with the main body to pivot to be opened and closed and to comprise a touch panel and a display panel; a sensor configured to sense opened and closed states of the display unit with respect to the main body; and a controller configured to, when the display unit is changed from the opened state to the closed state, stop an operation of the touch panel and then stop an operation of the display panel after stopping the operation of the touch panel. ### Claim 2 (depends on 1) The electronic apparatus of claim 1, wherein the sensor senses the opened and closed states of the display unit with respect to the main body by sensing magnetism of a magnet of the display unit. ### Claim 3 (depends on 1) The electronic apparatus of claim 1, wherein the sensor senses the opened and closed states of the display unit with respect to the main body by sensing a relative angle of a hinge that connects the main body and the display unit to each other. ### Claim 4 (depends on 1) The electronic apparatus of claim 1, wherein if the display unit is changed from the opened state to the closed state, the controller stops the operation of the touch panel and stops the operation of the display panel after the closed state is maintained for a predefined time. ### Claim 5 (depends on 1) The electronic apparatus of claim 1, wherein the controller stops the operation of the display panel and informs a basic input output system (BIOS) of the electronic apparatus that the operation of the display unit has been stopped, to enter a sleep mode. ### Claim 6 (depends on 1) The electronic apparatus of claim 1, wherein if the display unit is changed from the closed state to the opened state, the controller resumes the operations of the touch panel and the display panel. ### Claim 7 (depends on 1) The electronic apparatus of claim 1, wherein the controller stops the operation of the touch panel by generating a control signal to block an input of the touch panel or blocking power of the touch panel. ### Claim 8 (depends on 1) The electronic apparatus of claim 1, wherein the controller stops the operation of the display panel by generating a control signal to block an input of a signal output to the display panel or to block power of the display panel. ### Claim 9 (depends on 1) The electronic apparatus of claim 1, wherein the controller is realized as a microcomputer circuit. ### Claim 10 A method of controlling an electronic apparatus comprising a main body and a display unit configured to be combined with the main body to pivot to be opened and closed and to have a touch panel and a display panel, the method comprising: sensing opened and closed states of the display unit with respect to the main body; when the display unit is changed from the opened state to the closed state, stopping an operation of the touch panel; and after stopping the operation of the touch panel, stopping an operation of the display panel. ### Claim 11 (depends on 10) The method of claim 10, wherein a magnetism of a magnet of the display unit is sensed to sense the opened and closed states of the display unit with respect to the main body. ### Claim 12 (depends on 10) The method of claim 10, wherein a relative angle between the main body and the display unit is sensed to sense the opened and closed states of the display unit with respect to the main body. ### Claim 13 (depends on 10) The method of claim 10, wherein after a predefined time elapses from a time when the display unit is changed from the opened state to the closed state, the operation of the display panel is stopped. ### Claim 14 (depends on 10) The method of claim 10, further comprising: stopping the operation of the display panel and informing a BIOS that the operation of the display panel has been stopped, to enter a sleep mode. ### Claim 15 (depends on 10) The method of claim 10, further comprising: when the display unit is changed from the closed state to the opened state, resuming the operations of the touch panel and the display panel. ### Claim 16 (depends on 10) The method of claim 10, wherein a control signal to block an input of the touch panel is generated or power of the touch panel is blocked to stop the operation of the touch panel. ### Claim 17 (depends on 10) The method of claim 10, wherein a control signal to block an input of a signal output to the display panel is generated or power of the display panel is blocked to stop the operation of the display panel. ### Claim 18 (depends on 10) A non-transitory computer-readable recording medium to contain computer-readable codes as a program to execute the method of claim 10. ### Claim 19 An electronic apparatus comprising: a main body; a display unit combined with the main body, and having a touch panel and a display panel; and a controller configured to differently control operations of the touch panel and the display panel of the display unit according to a state of the display unit with respect to the main body. ### Claim 20 (depends on 19) The electronic apparatus of claim 19, further comprising: a sensor disposed to detect the state of the display unit with respect to the main body, wherein the sensor detects at least one of an angle between the display unit and the main body, a distance between a portion of the display unit and a portion of the main body, and a state of a hinge connecting the display unit and the main body to each other, as the state of the display unit. ### Claim 21 (depends on 19) The electronic apparatus of claim 19, further comprising: a sensor disposed to detect the state of the display unit with respect to the main body, wherein the sensor and the controller are disposed at the main body. ### Claim 22 An electronic apparatus comprising: a main body; a display unit movable with respect to the main body, and having a panel with an input function and a display function; and a controller configured to differently control the input function of the panel and the display function of the panel of the display unit according to a state of the display unit with respect to the main body. ### Claim 23 (depends on 22) The electronic apparatus of claim 22, wherein the controller deactivates the input function of the panel and maintains the display function within a period of time when the state of the display unit is detected. ### Claim 24 (depends on 22) The electronic apparatus of claim 22, wherein the controller deactivates the display function and maintains the deactivation of the input function of the panel after a period of time after the state of the display unit is detected. ### Claim 25 (depends on 22) The electronic apparatus of claim 22, wherein the input function and the display function are simultaneously activated when the electronic apparatus is turned on, and the input function and the display function are differently deactivated according to the state of the display unit.
