Abstract
A touch display device, a display panel, a touch-sensing method, a touch-sensing circuit, and a driving circuit, are discussed, which can detect a signal utilizing a pixel electrode and can remove a noise component that may be generated at the time of touch position sensing or fingerprint sensing while sensing a touch position or a fingerprint based on the detected signal, thereby improving sensing performance.
