  • Publication number: 20210319763
    Abstract: A gate driver on array (GOA) circuit and a display panel are provided. At least one reverse unit of a nth-stage GOA unit of the GOA circuit is a first reverse unit, which includes three reverse transistors. During an operation stage, when a potential of a first node is low, an input terminal of a maintenance unit is at a high potential, and when the first node is at a high potential, the input terminal of the maintenance unit is at a low potential. Only three transistors are used to achieve that a potential of the first node is opposite to a potential of a signal at the input terminal of the maintenance unit, which saves space.
