Embodiment Construction

[0041] 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.

[0042] 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

According to a GOA circuit and a display panel provided by the embodiment of the invention, the number of transistors electrically connected with a first node in the GOA circuit is reduced, so that the electric leakage path of the first node is reduced; and meanwhile, the GOA circuit can perform real-time compensation on the pixel circuit in the blank time, and thus the stability of the GOA circuit is further 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. However, the existing GOA circuit is complex, its allowable threshold deviation range is small, and its stability is poor. Contents of the invention [0003] Embodiments of the present application provide a GOA circuit and a display panel to solve the technical problem of poor stability of the GOA circuit in the prior art. [0004] The application provides a GOA circuit, including: [0005] ...
