    Abstract: A display device is disclosed. The display device includes a display and a diffractive optical element (DOE). The display is used to show an image. When a user looks at the image within a first viewing angle range, he can see a first observed image, and when he looks at the image within a second viewing angle range, he can see a second observed image. The diffractive optical element is disposed in the lighting direction of the display to diffract the light constructing the first observed image to the second viewing angle range, thereby converting the first observed image into a third observed image and converting the second observed image into a fourth observed image at the same time.

    Abstract: The present invention is directed to a structure, having first areas consisting of or comprising a network of organic polymer material and second areas consisting of a nematic and/or smectic liquid crystal material, comprising at least one or more nematic and/or smectic liquid crystals and a photoluminescent material, wherein the first and second areas alternate in at least a first plane, while the composition of the film is substantially invariable in at least one direction which is angular to the said first plane, or second areas are completely surrounded by first areas, and the said areas are located in a periodic pattern, wherein the nematic and/or smectic liquid crystal material in the second areas extends in the longitudinal direction of the said areas from one end of the area to the other, the structure being arranged between two substrates, at least one of which is light transmitting. The structure together with the substrates may be a Bragg grating and can be used as a DFB laser. It can be prepared by providing a homogeneous and isotropic mixture including a photocurable monomer/oligomer, a nematic and/or smectic liquid crystal, and a photoluminescent material, filling said mixture into the space between two substrates and irradiating same with a light field such that areas of the mixture are irradiated while others are not. Under the irradiation, the mixture separates into areas comprising photocured polymer and areas consisting or comprising liquid crystals and photoluminescent material.

    Abstract: The present invention discloses a widely wavelength tunable polychrome colloidal photonic crystal device whose optical Bragg diffraction stop bands and higher energy bands wavelength, width and intensity can be tuned in a continuous and fine, rapid and reversible, reproducible and predictable fashion and over a broad spectral range by a controlled expansion or contraction of the colloidal photonic lattice dimension, effected by a predetermined change in the electronic configuration of the composite material. In its preferred embodiment, the material is a composite in the form of a film or a patterned film or shape of any dimension or array of shapes of any dimension comprised of an organized array of microspheres in a matrix of a cross-linked metallopolymer network with a continuously variable redox state of charge and fluid content. The chemo-mechanical and electro-mechanical optical response of the colloidal photonic crystal-metallopolymer gel is exceptionally fast and reversible, attaining its fully swollen state from the dry shrunken state and vice versa on a sub-second time-scale. These composite materials can be inverted by removal of the constituent microspheres from the aforementioned colloidal photonic crystal metallopolymer-gel network to create a macroporous metallopolymer-gel network inverse colloidal photonic crystal film or patterned film or shape of any dimension optical Bragg diffraction stop bands and higher energy bands wavelength, width and intensity can be redox tuned in a continuous and fine, rapid and reversible, reproducible and predictable fashion and over a broad spectral range by a controlled expansion or contraction of the colloidal photonic lattice dimensions.

    Abstract: An electro-optic polarizor, grating assembly or cell (10) includes a first glass plate (12) to form the foundation of the cell. A first alignment surfactant (14) is coated on one surface of the first glass plate (12). Similarly, a second alignment surfactant (24) is coated on one surface of a second glass plate (22). A transparent interdigitated electrode pattern (30) is disposed between the second glass plate (22) and the second alignment surfactant (24). A thin film of homeotropically aligned nematic liquid crystal (40) is sandwiched between the first and second alignment surfactants (14) and (24) for applying a lateral electric field caused by the control voltage or signal (50) across the liquid crystal (40) to alter the optical properties of the liquid crystal (40) such that a polarization depended grating (60) is induced by the lateral electric field (50).
