Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0031] The transistors used in all embodiments of this application can be thin film transistors or field effect transistors or other devices with the same characteristics. Since the source and drain of the transistors used here are symmetrical, their source and drain can be interchanged. of. In the embodiment of the present application, in order to distinguish the two poles of the transistor except the gate, one pole is called the source, and the other pole is called the drain. According to th...

Abstract

The embodiment of the invention provides a GOA circuit and a display panel. The GOA circuit comprises an input module, an output module, an output control module and an inverter module. the phase inverter module is of a Darlington structure, so that the stable high potential of a fifth node can be maintained, and the high potential output of an enable signal during a light emitting period can be maintained; the potential of the first low-level signal is smaller than that of the second low-level signal, so that it is ensured that the level transmission signal, the first scanning signal and the second scanning signal do not oscillate, and the electric leakage phenomenon of the first node can be prevented; therefore, the stability of the GOA circuit can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a GOA circuit and a display panel. Background technique [0002] Array substrate gate drive technology (Gate Driver Array, referred to as GOA), is to integrate the gate drive circuit on the array substrate of the display panel to realize the driving method of progressive scanning, so that the gate drive circuit part can be saved, and it has the advantages of The advantages of reducing production cost and realizing narrow bezel design of the panel are used for various displays. [0003] Among them, the GOA circuit not only needs to output the scan signal, but also needs to output the enable signal, so it is necessary to set up multiple GOA circuits. In order to reduce the production cost and realize the narrow border design of the panel, the existing panel manufacturers set up a GOA circuit that can output the scan signal and the enable signal at the same time, but the...
