Embodiment Construction

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0037] The transistors used in all the embodiments of this application may be thin film transistors or field effect transistors or other devices with the same characteristics. Since the source and drain electrodes of the transistors used here are symmetrical, their sources and drains can be interchanged. of. In the embodiments of the present application, in order to distinguish the two electrodes of the transistor except the gate electrode, o...

Abstract

In the GOA circuit and the display panel provided by the present application, by adding an eighth transistor and a ninth transistor to the pull-down maintaining module, the first node can be pulled down to a lower potential through the eighth transistor and the ninth transistor, thereby improving the performance of the GOA circuit. stability.

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] Integrated gate driver circuit technology (Gate Driver on Array, GOA) integrates the gate driver circuit on the array substrate of the display panel, so that the gate driver integrated circuit part can be omitted, so as to reduce the product cost in terms of material cost and manufacturing process. cost. [0003] The existing GOA circuit needs to maintain the low level of the horizontal scanning signal for a period of time after outputting the horizontal scanning signal of the GOA unit of the current stage. However, since the transistor works for a long time, the electrical property of the transistor is easily damaged, so that the GOA circuit cannot work normally. SUMMARY OF THE INVENTION [0004] The embodiments of the present application provide a GOA circuit and a display panel, which can solve the...
