Abstract

The invention provides a shift register unit and a scanning circuit, which is used for solving a technical problem of poor reset ability of the shift register unit in the prior art. The shift registerunit comprises a node control circuit, a scanning control circuit, a single-stage reset circuit, a discharge control circuit, a signal output circuit and a global reset circuit, wherein the node control circuit is mutually electrically connected with the scanning control circuit through a node N2a, the node control circuit is mutually electrically connected with the single-stage reset circuit, the discharge control circuit and the signal output circuit through a node N1, and the node control circuit is mutually electrically connected with the signal output circuit through a node N2b.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register unit and a scanning circuit. Background technique [0002] At present, when a liquid crystal display (Liquid Crystal Display, LCD) is displayed, the gate lines in the LCD are generally scanned line by line through a gate drive circuit, and the thin-film transistor (Thin-film transistor, TFT) is controlled to open to input the display voltage to the pixel electrode. , so that through the electric field between the pixel electrode and the common electrode, the deflection of the liquid crystal molecules is controlled to realize the display function. A general gate drive circuit is composed of multiple shift register units cascaded. [0003] However, the existing shift register unit usually has poor reset capability when the device is turned on or off, which affects the display effect of the display panel and poor user experience. Contents of the invention [00...
