A display apparatus including a display panel, a touch panel, a data driver, a common voltage noise predictor and a touch position detector. The display panel includes a plurality of data lines and a plurality of pixels. The pixels are electrically connected to the data lines, respectively. The touch panel is configured to output a first touch signal based on a touch event. The data driver is configured to output a data voltage to the data line based on a data signal. The common voltage noise predictor is configured to output a common voltage noise compensating signal based on the data signal. The touch position detector is configured to detect a touch position based on the common voltage noise compensating signal and the first touch signal.
