    摘要: A display material and method and device thereof are provided. The display material is first formed by evenly mixing appropriate weight ratios of DFLCs, incurable nanoparticles, curable nanoparticles, and a photoinitiator. Next, the evenly mixed mixture is disposed between two parallel conducting transparent substrates, wherein an electrical field is conducted thereto and the DFLCs therein aligned to the direction of the applied electrical field. Concurrently, under the applied electrical field, some curable nanoparticles within the evenly mixed mixture, form short nano chains, initiating the photo initiator. The frame structure of short nano chains stabilize both the clear and scattering states, thereby the bistable characteristic was improved and the contrast ratio was enhanced as applied to bistable displays.

    摘要: A method for making broadband cholesteric liquid crystals with improved bandwidth. The method includes the main steps of: (a) preparing a polymerization mixture containing first and second chiral liquid crystals, wherein the first chiral liquid crystal possesses a cholesteric liquid crystal phase and the second chiral liquid crystal possesses a helix-inversion characteristic, and at least one of the first or second chiral liquid crystals contains a polymerizable functional group; and (b) subjecting the polymerization mixture to a polymerization reaction, wherein the polymerization reaction is conducted such that the first chiral liquid crystal will go through a helix-inversion phenomenon. In a preferred embodiment, the second chiral liquid crystal has a temperature-dependent helicity which exhibits a helix inversion characteristic at a helix inversion temperature.

    摘要: To form a brightness enhancement film of cholesteric liquid crystal, a photopolymerizable liquid crystal is first formed on a first substrate. A second substrate then is formed on the liquid crystal substance to form a sandwich structure. The sandwich structure is subsequently submitted to a lamination process that generates shear stress thereon. Finally, an energetic irradiation including UV irradiation is performed to solidify the layer of liquid crystal into a liquid crystal polymer film. The second substrate then is selectively removed. The above steps are repeated until a desired reflected wavelength range of the liquid crystal film is obtained.
