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.
