Abstract
An electronic device and a method for correcting an input coordinate of the electronic device are provided. The electronic device includes a pen input device configured to support an electromagnetic induction function and an electrostatic pen function; a touch screen including a digitizer pad, an electrostatic capacitive touch panel disposed above the digitizer pad, a digitizer pad controller configured to detect a recognition coordinate calculated from electromagnetic induction from the digitizer pad, and a touch panel controller configured to detect an input coordinate in relation to a change of an electrostatic capacitance from the touch panel; and a processor configured to generate inclination information of the pen input device and coordinate correction based on a write pressure of the pen input device, the recognition coordinate information provided by the digitizer pad controller, and the input coordinate information provided by the electrostatic capacitive touch panel controller.
