Abstract

See full text

A shift register is provided, which includes a blanking input circuit, a blanking control circuit, a blanking pull-down circuit, id='REI-00001' date='20250204' andid='REI-00001' a shift register circuitid='REI-00002' date='20250204' , and a twenty-ninth transistorid='REI-00002' . The blanking input circuit may provide a blanking input signal to a first control node id='REI-00003' date='20250204' according to a second clock signal.id='REI-00003' id='REI-00004' date='20250204' and comprise a first transistor id='REI-00004' The blanking control circuit may id='REI-00005' date='20250204' provide a first clock signal to a second control node and maintain a voltage difference between the first control node and the second control node, according to a voltage of the first control node.id='REI-00005' id='REI-00006' date='20250204' comprise a second transistor. id='REI-00006' The blanking pull-down circuit may provide a voltage of the second control node to a pull-down node according to id='REI-00007' date='20250204' theid='REI-00007' id='REI-00008' date='20250204' a id='REI-00008' first clock signal id='REI-00009' date='20250204' and comprise a third transistor and a third leakage-preventative transistorid='REI-00009' . The shift register circuit may provide a shift signal via a shift signal output terminal and a first drive signal via a first drive signal output terminal according to a voltage of the pull-down node.
