A display apparatus includes a display panel, a plurality of sensors, a read-out circuit, and a control circuit. The display panel includes a plurality of pixels receiving a data signal having a polarity reversed with respect to a common voltage to display an image. The sensors sense light to output sensing signals. The sensors may be integrated into the display panel. The read-out circuit is charged with the sensing signals generating charged signals in response to a sampling signal generated during a period in which the common voltage has a predetermined reference voltage level. The control circuit calculates a position on the display panel from the charged signals received signals from the read-out circuit.

Display apparatus

A data driver includes data lines, data voltage output parts that output data voltages to the data lines, and a data voltage sharing part connected to the data lines. The data voltage sharing part connects output terminals of two or more of the data voltage output parts to each other to charge-share the data voltages therebetween.
