    Abstract: Provided are a display panel, a detection method thereof and a display device. A scan driving circuit, signal pins and a first gating circuit are disposed in the display panel. Signal pins include a detection signal pin and an enable signal pin. The scan driving circuit includes scan drive units disposed in a cascade manner. The first gating circuit includes a first switch unit and a second switch unit. An input terminal of the first switch unit is electrically connected to a scan signal detection terminal of an Nth-stage scan drive unit. An input terminal of the second switch unit is electrically connected to a scan signal detection terminal of a first-stage scan drive unit. An output terminal of the first switch unit and an output terminal of the second switch unit are both electrically connected to the detection signal pin. The first switch unit is configured to turn on in a forward scan detection stage and turn off in a backward scan detection stage. The second switch unit is configured to turn on in the backward scan detection stage and turn off in the backward scan detection stage.

    Abstract: A shift register, a driving circuit and a display device are provided. The shift register comprises an output circuit, a node control circuit, and a first node charging circuit. The output circuit provides a signal at a first clock signal terminal or a signal at a first reference voltage terminal to a gate signal output terminal under a control of a signal at a first node or a control of a signal at a second node. The node control circuit controls levels of the signal at the first node and at the second node to be opposite. The first node charging circuit includes a first control terminal, and provides a signal at a first fixed voltage terminal to the first node under a control of a signal at the first control terminal during a charging period of the first node in a non-scanning period.
