Abstract: A touch display apparatus integrated fingerprint sensor includes a plurality of pixels arranged in a display area, a plurality of touch sensor electrodes arranged in a touch sensor area overlapping with the display area, a plurality of fingerprint sensor electrodes arranged in a fingerprint sensor area which is spaced apart from the touch sensor area and overlaps with the display area, and a plurality of fingerprint lines overlapping with a plurality of touch sensor electrodes which is located in an area adjacent to the fingerprint sensor area and associated with driving of the plurality of fingerprint sensor electrodes. The plurality of fingerprint lines may include a fingerprint guard line surrounding the fingerprint sensor area, and a fingerprint electrostatic line surrounding the fingerprint sensor area. The fingerprint guard line and fingerprint electrostatic line increase sensor reliability by shielding the plurality of fingerprint sensor electrodes from external signals and electrostatic discharge.

Abstract: A touch sensor includes a plurality of touch driving electrodes arranged in each of a plurality of touch driving columns in a column direction, and a plurality of touch sensing electrodes arranged in each of a plurality of touch sensing columns in the column direction, the plurality of touch driving columns and the plurality of touch sensing columns being alternately arranged in a row direction. In each of the plurality of touch driving columns, two or more odd-numbered touch driving electrodes among the plurality of touch driving electrodes are substantially simultaneously driven during a first touch group driving period. In each of the plurality of touch driving columns, two or more even-numbered touch driving electrodes among the plurality of touch driving electrodes are substantially simultaneously driven during a second touch group driving period that is different from the first touch group driving period.
