The present disclosure provides a shift register unit, a gate driver circuit, and a display device, belonging to the field of display technology, which can solve the problem of unstable threshold voltage and current leakage of thin film transistors in existing shift register units. The shift register unit in the present disclosure includes: an input subcircuit, an output subcircuit, a pull-down control subcircuit, a pull-down subcircuit, a first noise reduction subcircuit, a first auxiliary control subcircuit, and a second auxiliary control subcircuit. The first auxiliary control subcircuit is configured to write the third reference level signal to the pull-down control node when the pull-down node is the first reference level signal, and control the pull-down subcircuit to be closed to control the first noise reduction subcircuit to be open.

The present invention provides a detection device for a cassette comprising at least one supporting unit, each supporting unit comprising a plurality of supporting brackets which constitute a supporting plane, wherein the detection device comprises a sensing mechanism for detecting whether position of each of the supporting brackets in each supporting unit is within a predetermined range. In the present invention, through detecting positions of the supporting brackets in the cassette, and then judging whether the positions of the supporting brackets in each supporting unit are in a preset range, a supporting unit in which there is one or more bracket supporting brackets whose positions are not in the preset range can be maintained in time, and therefore, damage to the glass substrate due to large error in positions of the supporting brackets can be prevented.
