Zusammenfassung: | The invention discloses a fingerprint identification circuit, a driving method, a touch panel and a display device, relates to the technical field of display, and is used for solving the problem of low fingerprint identification sensitivity. The fingerprint identification circuit comprises a pressure-sensitive device, a reset module, a detection module and a reading module. When the reset module is in the enabled state, a reset signal provided by the reset signal end of the reset module can be written into the detection end so that the detection end can be reset, and then when the detection module is in the enabled state and if the pressure-sensitive device receives the pressure of a finger, the detection module can obtain an analog fingerprint signal generated by the pressure-sensitive device, and the analog fingerprint signal is transmitted to the detection end, so that the reading module performs fingerprint identification based on the analog fingerprint signal.
