摘要： A reflective-type diffraction grating structure for use in color display devices such as liquid crystal displays (LCDs). It contains: (1) a plurality of micro-lenses each having a smooth top surface and a blazed zig-zag-shaped grating surface at the bottom; (2) an optical coating formed below the zig-zag-shaped grating surface; and (3) a reflective member formed below the optical coating. With the cooperative actions of the zig-zag-shaped grating surface, the optical coating layer, and the reflective member, an incident light, when reflected, is separated into repeated sequences of red, green, and blue color components and a black matrix segregating the red, green, and blue color components. A sequence of micro-light valves are placed in the path of the reflected incident light to block the undesired color components. The reflective-type diffraction grating structure dispenses with the need for the various layers of color filters. As a result, it improves the brightness of the image and reduces power consumption, as well as reducing the manufacturing cost.

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.

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.
