Array substrate gate driving circuit, display panel and display device

Abstract

The invention discloses an array substrate gate driving circuit, a display panel and a display device. The driving circuit comprises a first transistor and a second transistor, wherein a control electrode of the first transistor is connected with a first pull-down node, a first electrode of the first transistor is connected with a second grid signal output terminal, and a second electrode of the first transistor is connected with a second clock signal terminal; a control electrode of the second transistor is connected with a second pull-down node, a first electrode of the second transistor is connected with a first grid signal output terminal, and a second electrode of the second transistor is connected with a first clock signal terminal; the first transistor is used for outputting a second clock signal to the second grid signal output terminal so as to enable the second grid signal output terminal to keep high-level signals at a non-selected output stage; the second transistor is used for outputting a first clock signal to the first grid signal output terminal so as to enable the first grid signal output terminal to keep high-level signals at a non-selected output stage. Thus, the problem that high-level signal fluctuation occurs at the non-selected output stages is effectively avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate gate drive circuit, a display panel and a display device. Background technique [0002] In some display panels, a strikethrough line in each row of GOA (Gate driver On Array, array substrate row driving technology) will be kept in a high state, so that the TFT (Thin Film Transistor, thin film transistor) in the corresponding pixel unit ) tube applies a forward voltage, but because the GOA is in a floating state when outputting a high-level signal, the floating state will be fluctuated by other voltage changes, so it is impossible to accurately predict the forward voltage applied to the TFT tube, and thus cannot achieve The effect of TFT tube compensation. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the first object of the prese...
