Abstract:
A touch panel, a driving method thereof, and a display device are disclosed. The touch panel includes a touch detection structure and a fingerprint identification structure; the touch panel includes a first electrode, a circuit structure, and a piezoelectric layer which are stacked. The first electrode includes a plurality of first sub-electrode strips arranged in a first direction and extending in a second direction, and the circuit structure includes a plurality of circuit sub-structures arranged in an array in the first direction and the second direction, each of the circuit sub-structures includes a detection electrode; in the first direction, an orthographic projection of each of the first sub-electrode strips on a main surface of the piezoelectric layer covers orthographic projections of detection electrodes of at least two circuit sub-structures on the main surface of the piezoelectric layer.
