Abstract
The present invention provides a fingerprint identification panel and the fingerprint identification circuit thereof, which comprise a gate driving circuit, a source driving circuit, and a detection circuit. The gate driving circuit is coupled to a plurality of gate lines, outputs a plurality of gate signals to the plurality of gate lines, and controls a state transition of the plurality of gate signals. The source driving circuit is coupled to a plurality of source lines. The detection circuit is coupled to the plurality of source lines or to a portion of the plurality of source lines. The detection circuit detects the levels of the plurality of signals on the coupled source lines when the state of the gate signal is changed and generates a plurality of detection signals.
