Abstract: A mobile terminal and a method for input control of the mobile terminal are provided. The method comprises: when detecting that the module terminal is in a coordinate control state, inputting a latitudinal position of a target point on a display screen; inputting a longitudinal position of the target point on the display screen; a main control module of the mobile terminal determining the latitudinal and longitudinal position of target point on the display screen according to a latitudinal analog voltage of a display screen latitudinal coordinate controller and a longitudinal analog voltage of a display screen longitudinal coordinate controller, and displaying the target point position on the display screen; the main control module executing a selection operation of an area corresponding to the target point position on the display screen after receiving a triggering indication of the target point position of the display screen.

Abstract: The present document discloses a mobile terminal and a method for input control of the mobile terminal. The method includes: inputting a horizontal position of a target point on a display screen; inputting a longitudinal position of the target point on the display screen; when detecting that the mobile terminal is in a coordinate key control state, a main control apparatus of the mobile terminal determining a target point position of the target point on the display screen according to a horizontal analog voltage of a display screen horizontal coordinate controller and a longitudinal analog voltage of a display screen longitudinal coordinate controller, and displaying the target point position on the display screen; the main control apparatus, after receiving a triggering indication of the target point position of the display screen, executing a selection operation of an area corresponding to the target point position on the display screen.
