Abstract

The invention discloses a GOA circuit and a display panel. A thirteenth transistor can be added into a pull-down maintenance module, so that the voltage difference between a source electrode and a drain electrode of an eleventh transistor is reduced; in addition, a twentieth transistor can be additionally arranged in the pull-down maintenance module, so that the voltage difference between a grid electrode and a source electrode of a nineteenth transistor is reduced, the electric leakage of a first node is inhibited, and the high-temperature limit of the first node is improved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to the technical field of mobile equipment, and 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] Since the existing products all need to pass the product reliability test, and the product reliability test takes a long time, and the high temperature needs to be maintained during the product reliability test. However, in the high temperature condition of the GOA circuit, some transistors will have serious leakage phenomenon, which will cause serious leakage phenomenon of the GO...
