  • Publication number: 20190204648
    Abstract: The present disclosure provides a display panel, a preparation method thereof, and a liquid crystal display. The display panel includes a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer between the first substrate and the second substrate, and a polymerizable monomer arranged in the liquid crystal layer; wherein a plurality of polymer walls are arranged in the liquid crystal layer; the polymer wall contacts to the first substrate and the second substrate, and a polymerization direction of the polymerizable monomer in the polymer wall is substantially perpendicular to a thickness direction of the polymer wall. By arranging a plurality of polymer walls to limit the flow of the liquid crystal in a liquid crystal layer, improve an edge roughness of a polymer wall, so as to improve light leakage from an edge of pixels and improve a display effect.

  • Patent number: 10222670
    Abstract: Provided are a liquid crystal display device and a manufacture method thereof. The liquid crystal display device is a blue phase liquid crystal display device. The alignment layer is not required. The liquid crystal composition forming the liquid crystal layer comprises liquid crystal material, quantum dots material mixed in the liquid crystal material, polymeric monomer and chiral material; the polymeric monomer is polymerized to form a polymer network under a blue phase temperature range as forming the liquid crystal layer, which can stabilize the blue phase liquid crystal, and thus to expand the blue phase temperature range. The grain size of the quantum dots material in the liquid crystal composition is in the nano scale, which can expand the blue phase liquid crystal temperature range. Namely, the blue phase temperature range of the liquid crystal material has already been expanded before the polymeric monomer is polymerized.

  • Publication number: 20180203266
    Abstract: The invention provides a liquid crystal medium mixture including a liquid crystal material, an antioxidant and at least one kind of polymerizable monomer capable of undergoing polymerization reaction under ultraviolet light irradiation. Under an ultraviolet light irradiation, the antioxidant would make the polymerizable monomer be slowly polymerized to form a homogeneous polymer network in the liquid crystal material and thereby make the liquid crystal material have a fast-response speed when a voltage is applied thereto. The invention further provides a liquid crystal display panel.
