  • Publication number: 20240126124
    Abstract: Liquid crystal display panels are provided. In the display panel, a first polarization direction of a first polarizer is perpendicular to a second polarization direction of a second polarizer; each pixel unit includes a pixel electrode including a trunk electrode, the trunk electrode includes a first and a second trunk electrodes disposed along a first direction and a second direction, respectively; an angle between the first direction and the first polarization direction is different from a right angle; the trunk electrode defines an area where the pixel unit is located as four domains, each domain is provided with branch electrodes; the branch electrodes in adjacent domains arranged in a row direction form a first angle and a second angle with the first polarization direction respectively, the first angle ranges from 0 to 30 degrees, and the second angle ranges from 60 degrees to 90 degrees.

  • Patent number: 11634879
    Abstract: A tower packer for packing cement slurry of a jacket is disposed between a steel pile and an inner sleeve. It includes a supporting ring, sealing rings and a limiting ring. The supporting ring and the limiting ring are respectively installed on an outer surface of the inner sleeve in the steel pile. A plurality of sealing rings stacked from top to bottom along the sleeving direction of the inner sleeve are arranged between the supporting ring and the limiting ring. Each sealing ring is hermetically and slidably connected along a radial direction. The sealing ring at the bottom is always supported by the supporting ring. The sealing ring at the top abuts a lower surface of the limiting ring. When the inner sleeve is sleeved into the steel pile, the outer surface of the sealing ring with maximum outer diameter hermetically abuts the inner surface of the steel pile.
