  • Publication number: 20190361272
    Abstract: A liquid crystal display is configured such that a composite layer thereof is transparent to incident light in one voltage condition (e.g., in the absence of an applied voltage) and scatters incident light out of the display in another voltage condition (e.g., when a voltage is applied). The liquid crystal display does not need polarizers or color filters.

  • Patent number: 10397782
    Abstract: Examples relate to a method and a device for wireless access authentication. The method is applied to an intelligent gateway which is previously associated with account information of a user. The intelligent gateway may receive an access authentication packet comprising an authentication identification indicating a terminal device; the intelligent gateway may construct an identity verification packet comprising an authentication identification indicating the terminal device and an association account identification indicating an account registered on the intelligent gateway; the intelligent gateway may send the identity verification packet to a cloud server; the intelligent gateway may permit a terminal device corresponding to authentication identification carried in a verification success packet returned by the cloud server to pass the access authentication.

  • Publication number: 20170269401
    Abstract: A display panel and a manufacturing method thereof are provided. Each pixel of the display panel includes a transmission region and a reflection region, and the display panel includes a first polarizer, a first base substrate, a first alignment layer, a liquid crystal layer, a second alignment layer, a second base substrate, and a second polarizer. A reflection layer is provided between the second alignment layer and the second polarizer in the reflection region. The liquid crystal layer in the reflection region includes nematic liquid crystal and a polymer network. The liquid crystal layer in the transmission region includes a liquid crystal mixture including the nematic liquid crystal and polymerizable monomers. The polymer network in reflection region is formed by polymerizing the polymerizable monomers in the liquid crystal mixture.

  • Publication number: 20160363794
    Abstract: This invention discloses a liquid crystal display (LCD) device and a method of manufacturing the same. The LCD device comprises a first substrate and a second substrate opposing each other, and a nematic liquid crystal layer disposed therebetween and comprising a nematic liquid crystal and a polymer network. The polymer network is formed by irradiation polymerization of a functional monomer in a nematic liquid crystal mixture. The polymer network can reduce the scattering phenomena caused by the refractive index mismatch between liquid crystal and polymer in the prior LCD devices and significantly reduce the dark-state light leakage, so that the contrast is improved. Moreover, since there is no polymer projection disposed on the alignment layer according to the invention, the dark-state light leakage caused by polymer projections is avoided and thus the contrast is further improved.
