Abstract: In an electronic device, touch coordinates, which are not pixel shift calibrated, are not transmitted from an application processor to a timing controller. Instead, pixel shift data are supplied to a touch position calculating unit disposed in a driving circuit or the application processor, and the touch position calculating unit generates pixel shift calibrated touch coordinates by reflecting the pixel shift data when calculating a touch position based on detection signals from a touch sensor. Accordingly, it is not necessary to transmit touch coordinates, which are not pixel shift calibrated, from the application processor to the timing controller, thereby decreasing a delay and power consumption due to frequency transception.
