Embodiment Construction

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this 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.

[0035] 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. ...

Abstract

The embodiment of the invention provides a GOA circuit and a display panel. Suppression electrodes are correspondingly disposed at a tenth transistor and an eleventh transistor, and the suppression electrodes are electrically connected with a reset signal, and the threshold voltage excursion of the tenth transistor and the eleventh transistor is suppressed by the reset signal during a reset period, thereby improving the display quality of the display panel.

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] GOA (full name in English: Gate Driver on Array, full name in Chinese: integrated gate drive circuit) technology integrates the gate drive circuit on the array substrate of the display panel, so that the part of the gate drive integrated circuit can be saved to save material cost and The production process reduces the product cost in two aspects. [0003] The transistors in the existing GOA circuit have a threshold voltage shift problem, which leads to poor quality of the display panel. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide a GOA circuit and a display panel, which can solve the technical problem that the transistors in the GOA circuit have shifted threshold voltages, resulting in poor quality of the display panel. [0005] An embodim...
