Abstract
In a display apparatus, one frame includes a first sub-frame in which a previous image is held and a second sub-frame in which a present image is displayed. A plurality of sensors recognizes an object disposed on a display panel and sequentially outputs sensing signals in response to scan signals. Sensing signals are divided into a first sensing signal read out during a first sub-frame and a second sensing signal read out during a second sub-frame, and a control circuit generates a noise free signal using the first and second sensing signals. Thus, a coordinate value indicating the position of the object may be generated based on the noise free signal, thereby preventing mis-operation or malfunction caused by the noise.
