Abstract: 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.

Abstract: A display device includes a display panel including data lines, gate lines, and pixels connected to the data lines and the gate lines, a data driver configured to drive the data lines, a plurality of gate drivers, each configured to drive a corresponding portion of the gate lines, and a plurality of feedback lines connected to one of the data lines at a plurality of measurement positions corresponding to the plurality of gate drivers. The data driver applies a test voltage to the data line, receives the test voltage as a plurality of feedback voltages through the plurality of feedback lines, and determines gate shift amounts at the plurality of measurement positions corresponding to the plurality of gate drivers based on the plurality of feedback voltages. The gate drivers apply gate signals to the gate lines that are shifted by the determined gate shift amounts.
