  • Publication number: 20240021765
    Abstract: In an array substrate of the present invention, only two insulating layers are arranged on a planarization layer. Compared with conventional techniques that require at least four insulating layers arranged on the planarization layer, a number of the insulating layers arranged on the planarization layer is reduced. Therefore, a number of photomasks is reduced in a manufacturing process of the array substrate, and the manufacturing process is simplified. The present invention also provides a manufacturing method of the array substrate, and a display panel.

  • Publication number: 20240005829
    Abstract: A gate driving circuit and a display panel are disclosed. A pull-up control module and a pull-down module of each stage gate driving unit are connected to a first node. A thin film transistor in the pull-up control module and/or pull-down module that is connected to the first node is an oxide thin film transistor, such that a leakage current of the first node is reduced due to the advantage of the small off-state leakage current of the oxide thin film transistor. Therefore, the voltage level of the first node can remain stable during a pull-up stage and a touch suspension stage.
