SHIFT REGISTER UNIT AND DRIVING METHOD, ROW SCANNING DRIVE CIRCUIT, AND DISPLAY DEVICE

摘要

A shift register unit and driving method, row scanning drive circuit, and display device, wherein the shift register unit comprises an input terminal (IN), a reset terminal (RESET) and an output terminal (OUT), and further comprises: an input unit (11) connected to the input terminal (IN) and a first node (PU) and configured to pull up the power level at the first node (PU) when the input terminal (IN) is at an effective power level; an output unit (12) connected to the first node (PU) and the output terminal (OUT) and configured to pull up the power level at the output terminal (OUT) on the basis of a first clock signal (CK) when the first node (PU) is at a high power level; a reset unit (13) connected to the reset terminal (RESET) and the first node (PU), and configured to pull down the power level at the first node (PU) when the reset terminal (RESET) is at an effective power level; and a first pull-down unit (14) connected to the output terminal (OUT) and comprising a control terminal and configured to pull down a power level at the output terminal (OUT) when the control terminal is at an effective power level. The invention can resolve the problem of a floating connection state of a row scanning drive circuit affecting output stability.
