Patent ID: 10121047

Abstract:
The present disclosure provides a fingerprint identification device, a touch panel, an input device and a fingerprint identification method. The fingerprint identification device includes a fingerprint identification module, gate lines and signal lines. The gate lines and the signal lines cross so as to define a plurality of sensing regions including a thin film transistors and a sensing electrode connected to the thin film transistors. A gate electrode of the thin film transistor is connected to the corresponding gate line, a source electrode is connected to the corresponding signal line, and a drain electrode is connected to the corresponding sensing electrode. The signal lines include signal-transmitting lines and signal-receiving lines, the sensing electrodes include transmitting electrodes and receiving electrodes. An electric field is generated between the transmitting electrode and the receiving electrode adjacent to the transmitting electrode, and a direction of the electric field is from the transmitting electrode to the receiving electrode adjacent to the transmitting electrode. The fingerprint identification module is connected to the signal-receiving lines, and determines, by detecting the intensity of the electric field when a finger is in the electric field, a fingerprint of the finger.
