Embodiment Construction

[0041] 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.

[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. ...

Abstract

According to the GOA circuit and the display panel provided by the embodiment of the invention, a reset module is arranged in each stage of GOA unit, so that each stage of GOA unit can output high potential before a frame is ended such that gates of all display areas are opened, and charges of all pixels of the display regions are discharged completely; then, each stage of GOA unit outputs a low potential, and all gates in the display area are set to be low potentials; that is to say, the embodiment of the invention can improve the capacity of electric black sweeping and normal black sweepingunder an abnormal condition; and the stage transmission stability of the GOA circuit of the high-resolution display panel 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] Gate Driver On Array, referred to as GOA, is a technology that utilizes the existing thin-film transistor liquid crystal display array process to fabricate the line scan drive signal circuit on the array substrate to realize the drive mode of scanning line by line. [0003] As the resolution of the display panel becomes higher and the number of scanning lines increases, the probability of stage transmission errors also increases. At the same time, abnormal power failures may occur during customer operations. If there is no The functions of power-off, black-sweeping and reset often cause residual charge and cause abnormal display. Therefore, the cascading stability of the GOA circuit of the high-resolution display panel is poor. Contents of the invention [0004] The purpose of the embodiments of the p...
