Display apparatus capable of image scanning and driving method thereof

A display apparatus capable of image scanning, the apparatus comprising a contact sensor, wherein the contact sensor comprises:

• a pixel electrode forming a contact capacitance by contact with a contact means;
• a reset transistor including a first electrode connected to a node where the contact capacitance is formed, and a second electrode connected to a first terminal supplying a first signal to the node;
• and
• an amplifying transistor including a third electrode connected to the node, and a fourth electrode connected to a second terminal supplying a second signal,
• wherein a passivation layer is formed between the pixel electrode, and the reset transistor and the amplifying transistor,
• wherein the pixel electrode is connected to the first electrode of the reset transistor or the third electrode of the amplifying transistor through a contactor formed through an end of the passivation layer,
• wherein the amplifying transistor generates a current varying depending on a voltage charged in the contact capacitance.
