Abstract: An array substrate is provided. The array substrate includes a substrate, a light-shielding layer, and an active layer. The light-shielding layer is disposed on the substrate, and the active layer is disposed on the light-shielding layer. Wherein, an orthographic projection of the active layer on the substrate is positioned within an orthographic projection of the light-shielding layer on the substrate. The present disclosure prevents the active layer from forming ramps and then breaking by allowing the orthographic projection of the active layer on the substrate to be positioned within the orthographic projection of the light-shielding layer on the substrate, thereby ensuring performances of the array substrate.

Abstract: A thin film transistor and a display panel are provided. A first dimension of a first transmission portion electrically connected to a source heavily-doped portion is different from a second dimension of a second transmission portion electrically connected to a drain heavily-doped portion, so that an intensity of an electric field of carriers transmitted by the transmission portion corresponding to the larger one of the first dimension or the second dimension is smaller when the thin film transistor is turned on, thereby reducing the bombardment effect of the carriers on a source or a drain and improving the stability of thin film transistor.

A first driving signal can be output through a first output node, and at the same time, a second driving signal with a same phase as the first driving signal can be output through a second output node, and a gate driving sub-module and an in-phase output sub-module share the first output node and a pull-down node, which simplifies a circuit topology of the gate driving circuit.

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.

Abstract: A display panel and a gate driving circuit are provided. The gate driving circuit utilizes the pull-down control module to periodically pull up and pull down the voltage level of the second node. The voltage level of the second node is periodically a high voltage level. This effectively reduces the time duration when the second node corresponds to the high voltage level. After the TFTs electrically connected to the second node are forward biased, the TFTs could have sufficient recovery time. This solution effectively improves the bias condition of the TFTs in the pull-down control module and thus makes the circuit more stable and raises the reliability of the circuit.
