Abstract: A display device includes a pixel unit including first pixels connected to a data line and second pixels connected to the data line; a sensing unit overlapping the first and second pixels, the sensing unit including sensing electrodes; and a sensing controller for receiving a sensing signal from at least some of the sensing electrodes in accordance with a sensing enable signal having a sensing-on level. In a first frame period, at least two of first data voltages having different levels are applied through the data line to the first pixels and second data voltages having the same level as each other but different from the first data voltages are applied through the data line to the second pixels. In the first frame period, the sensing enable signal has a sensing-off level while the first data voltages are applied and the sensing-on level while the second data voltages are applied.

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.
