Abstract

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.
