Abstract
A display apparatus capable of image scanning and a driving method thereof are provided. A display apparatus capable of image scanning includes a plurality of contact sensors each of which includes an N-type transistor, a P-type transistor connected to a gate electrode of the N-type transistor, and a sensing capacitor, the plurality of contact sensors being arranged so as not to cover a unit color pixel area of a color filter layer; a first scan line to which a selective signal is periodically applied, the first scan line being connected to a source electrode of the N-type transistor; a second scan line to which a selective signal is applied followed by the first scan line, the second scan line being connected to the gate electrode and source electrode of the P-type transistor; and a readout line connected to the drain electrode of the N-type transistor.
