Abstract
According to an embodiment, the present invention provides a display apparatus capable of image scanning and a driving method thereof.According to an embodiment, the present invention provides a display apparatus capable of image scanning, including a plurality of contact sensors, each of them being arranged so as not to overlap a unit color pixel of a color filter layer and including only one sensing transistor generating a leakage current corresponding to the strength of light reflected from an outside object, a scan line applied with a selective signal selecting at least a part of the contact sensors among the plurality of contact sensors, and a readout line receiving an output signal corresponding to the amount of electric charge charged in a parasitic capacitance of the sensing transistor by the leakage current from a contact sensor applied with the selective signal.
