Claim 0:
1. An apparatus for sensing a stylus, comprising:
a stylus sensor that is disposed on a display area of a display device that drives a plurality of pixels according to a vertical synchronization signal and a horizontal synchronization signal, and includes a plurality of first electrodes configured to sense a stylus input in a first direction when the stylus is on the stylus sensor and a plurality of second electrode configured to sense a stylus input in a second direction when the stylus is on the stylus sensor; and
a driver/receiver configured to apply a driving signal to at least one of the plurality of first electrodes and the plurality of second electrodes during a first section
in synchronizing with at least one synchronization signal of the horizontal synchronization signal and the vertical synchronization signal, and receive a detection signal from at least one of the plurality of first electrodes and the plurality of second electrodes during a second section after the first section in synchronizing with at least one synchronization signal of the horizontal synchronization signal and the vertical synchronization signal.
