  • Publication number: 20210287596
    Abstract: A shift register and a display device are provided. A first control device, a second control device and an output device of the shift register all receive a first power signal and a second power signal as working power signals. The first control device controls a signal of a first node and a signal of a second node in response to a first drive signal. The second control device controls the signal of the first node in response to a second drive signal. The output device outputs a third drive signal in response to the signal of the first node or the signal of the second node, and the third drive signal is generated and outputted by utilizing the first drive signal and the second drive signal, and simplifying a circuit configuration of the shift register for generating the third drive signal.

  • Publication number: 20200135774
    Abstract: Provided are an inverter circuit structure, a gate driving circuit and a display panel. The inverter circuit structure includes a PMOS transistor and an NMOS transistor, and further includes a first active layer, a gate layer, a second active layer, a first insulating layer between the gate layer and the first active layer, and a second insulating layer between the gate layer and the second active layer. An orthographic projection of the gate on the first active layer is a first region, and a portion of the first active layer in the first region has substantially a same thickness. An orthographic projection of the gate on the second active layer is a second region, and a portion of the second active layer in the second region has substantially a same thickness.

  • Publication number: 20120227353
    Abstract: A method of construction and installation of a large-span cylindrical reticulated shell comprises: installing a mother vault on the ground by a bulk method; pushing the mother vault gradually during the installation, so as to be match with a lifting device for lifting the extension tail end of the mother vault; adjusting the height of the extension tail end to allow the extension tail end to be maintained at a ground level for ground installation construction; and after the installation of the mother vault is completed, using a high-altitude overhanging construction method to install the other reticulated vaults adjacent to the mother vault, respectively, in sequence along the axial extending direction of the mother vault until the completion of installation of the entire large-span cylindrical reticulated shell is completed.
