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.

Abstract: The present application discloses a gate driving circuit and a display panel. The gate driving circuit comprises a plurality of cascaded gate driving modules. 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 thin-film transistor (TFT) having a vertical structure and an electronic device are provided. The TFT having the vertical structure includes an insulating substrate and an active layer disposed on the insulating substrate. The active layer includes a first conductive part, an active section, and a second conductive part which are stacked. An orthographic projection of the first conductive part on the insulating substrate partly overlaps an orthographic projection of the second conductive part on the insulating substrate. Therefore, contamination ions may be prevented from entering the active section from the insulating substrate during manufacturing processes of the TFT. Thus, reliability of performance of the TFT may be improved.
