Gate drive circuit

Abstract

The invention provides a gate driving circuit. The gate drive circuit comprises shift temporary storage circuits which are coupled in series, wherein the shift temporary storage circuit of the Nth stage comprises a direction selection circuit, a voltage regulation circuit, a pull-down circuit and an output stage circuit. The direction selection circuit generates a first driving signal on the first driving end. The voltage adjusting circuit pulls up the second driving signal according to the first scanning direction signal or the second scanning direction signal. The pull-down circuit pulls down the second driving signal according to the first scanning direction signal or the second scanning direction signal based on the pre-stage gate driving signal and the post-stage gate driving signal. The output stage circuit generates an Nth-stage gate driving signal according to the first driving signal and the second driving signal.

Description

technical field [0001] The present invention relates to a gate driving circuit, and in particular to a gate driving circuit of a display device. Background technique [0002] With the advancement of electronic technology, automotive panels have become more and more widely used in recent years, and the issues of safety assessment and reliability of display panels have also attracted more and more attention from consumers. [0003] However, in the technology of the display panel, the pull-down circuit in the existing shift register circuit often has a race condition, which causes a large current in the leakage path of the pull-down circuit. In this case, the driving end of the shift register circuit that intends to perform the charging operation will be affected by the competition phenomenon, resulting in an unexpected situation, which seriously affects the reliability of the entire circuit.
