  • Patent number: 11989499
    Abstract: Embodiments of the present application provide a method and an apparatus for adjusting metal wiring density. By detecting metal wiring density in each of metal density detection windows in a target layout, a region in which the metal wiring density is greater than a preset density threshold can be quickly positioned in the target layout, thereby improving the layout correction efficiency; then a power fill mesh in a target metal density detection window in which the metal wiring density is greater than the preset density threshold is cropped multiple times, until the metal wiring density in each of the metal density detection windows is less than or equal to the preset density threshold, such that sufficient power fill meshes are retained in the target layout while the metal wiring density of the target layout is less than or equal to the preset density threshold.

  • Publication number: 20240127732
    Abstract: A shift-register unit, a grid driving circuit and a displaying device, which relates to the technical field of displaying. In the present disclosure, the oxide-semiconductor layers of the oxide thin-film transistors may be delimited into regions according to the total channel widths and the channel lengths required by the oxide thin-film transistors in the shift-register unit, wherein the sum of the widths of the independent semiconductor branches obtained by the delimitation is equal to the required total channel width. Accordingly, one oxide thin-film transistor can realize the required total channel width by using the one or more semiconductor branches, to ensure the normal operation of the oxide thin-film transistor, whereby the oxide-semiconductor layers of the different oxide thin-film transistors can be configured differently, to realize the purpose of reducing the border frame of the displaying device.
