         5 . The electronic device according to  claim 4 , wherein when the predefined function is locked, the controller is further operable to:
 perform the predefined function according to a stored input, and   display the predefined function on the display module, if the predefined character is entered as a first character of the password and then deleted, and if the correct password is entered.   
     
     
         6 . The electronic device according to  claim 1 , wherein:
 the input module is located on the display module;   the input module comprises a touch receiving module operable to receive a touch operation; and   the predefined function is associated with a predefined icon displayed on the display module.   
     
     
         7 . The electronic device according to  claim 6 , wherein when the predefined function is locked, the controller is further operable to:
 perform the predefined function according to the input, if a period-of-time when the touch receiving module on the display receives a touch on the predefined icon is within a predefined period-of-time, and if the correct password is entered; and   move the predefined icon if the period-of-time exceeds the predefined period-of-time, and if the correct password is entered.   
     
     
         8 . A method for operating an electronic device, comprising:
 receiving an input for performing a predefined function associated with the input;   receiving a password;   deactivating a lock function to unlock the predefined function, if the input is received and if the password is correct; and   displaying the predefined function on a display module, if the input is received and if the password is correct.   
     
     
         9 . The method according to  claim 8 , further comprising storing the input. 
     
     
         10 . The method according to  claim 8 , further comprising performing the predefined function. 
     
     
         11 . The method according to  claim 8 , wherein the predefined function is associated with a predefined character displayed on a key. 
     
     
         12 . The method according to  claim 11 , further comprising when the predefined function is locked:
 performing the predefined function according to a stored input, and   displaying the predefined function on the display module, if the predefined character is entered as a first character of the password and then deleted, and if the correct password is entered.   
     
     
         13 . The method according to  claim 8 , wherein the predefined function is associated with a predefined icon displayed on the display module. 
     
     
         14 . The method according to  claim 13 , further comprising when the predefined function is locked:
 performing the predefined function according to the input, if a period-of-time when a touch receiving module on the display module receives a touch on the predefined icon is within a predefined period-of-time, and if the correct password is entered; and   moving the icon if the period-of-time exceeds the predefined period-of-time, and if the correct password is entered.   
     
     
         15 . A non-transitory computer readable storage medium comprising computer-executable instructions for operating a mobile electronic device, the computer-executable instructions comprising:
 receiving an input for performing a predefined function associated with the input;   receiving a password;   deactivating a lock function to unlock the predefined function, if the input is received and if the password is correct; and   displaying the predefined function on a display module, if the input is received and if the password is correct.   
     
     
         16 . The non-transitory computer readable storage medium of  claim 15  further comprising computer-executable instructions comprising storing the input. 
     
     
         17 . The non-transitory computer readable storage medium of  claim 15  further comprising computer-executable instructions comprising performing the predefined function. 
     
     
         18 . The non-transitory computer readable storage medium of  claim 15  further comprising computer-executable instructions comprising when the predefined function is locked:
 performing the predefined function according to a stored input, and 
 displaying the predefined function on the display module, if a predefined character is entered as a first character of the password and then deleted, and if the correct password is entered. 
 
     
     
         19 . The non-transitory computer readable storage medium of  claim 15  wherein the predefined function is associated with a predefined icon displayed on the display module. 
     
     
         20 . The non-transitory computer readable storage medium of  claim 19  further comprising computer-executable instructions comprising when the predefined function is locked:
