Abstract
A touch display panel includes touch detection electrodes and fingerprint recognition electrodes that share a common electrode layer. The pixel electrodes function as a drive pixel layer to induce capacitive coupling with respect to the fingerprint recognition electrodes, based on which operations of displaying, touch detection, and fingerprint recognition are carried out in a time sharing manner. The touch display panel requires no integration of separately made fingerprint recognition device and a touch display panel, and fingerprint detection can be realized with an existing layered structure of the touch display panel to thereby effectively save the manufacturing cost of the touch display device and achieve an effect of integrating a fingerprint recognition device and a touch display panel. A touch display device that includes the touch display panel is also provided.
