  • Patent number: 8094270
    Abstract: An oblique angle deposition is used to provide an A-plate optical retarder having at least one dense, form-birefringent layer. According to one embodiment, the dense, form-birefringent layer(s) are deposited as part of an FBAR stack to provide an all-dielectric full-function A/?C-plate trim retarder for LCD birefringence compensation. Advantageously, the dense structure of the full-function A/?C-plate trim retarder offers high durability and/or stability, thus making it well suited for providing polarization compensation in high light flux polarization-based projection systems.

A TFT substrate is disposed on a rubbing stage and a projecting portion is formed on a surface of the TFT substrate by TFT wiring. The projecting portion on the surface causes an unrubbed portion, that is, a rubbing shadow particularly at the downstream of rubbing. In a rubbing step, two rubbing rollers that rotate in different directions are provided and the TFT substrate is rubbed in contact with the two rubbing rollers that rotate in different directions, which eliminates the influence of the rubbing shadow.

    Abstract: A new light modulating material using interconnected unidirectionally oriented microdomains of a liquid crystal, dispersed in a stressed polymer structure, is provided. The light modulating material is prepared by dissolving the liquid crystal in an uncured monomer and then curing the monomer so that the polymer forms a well-developed interpenetrating structure of polymer chains or sheets that is uniformly dispersed through the film. When the film is subjected to stress deformation the liquid crystal undergoes a change in its unidirectional orientation. The concentration of the polymer is high enough to hold the shear stress, but is as low as possible to provide the highest switch of the phase retardation when an electric field is applied. The new materials are optically transparent and provide phase modulation of the incident light opposed to the low driving voltage, linear electro-optical response, and absence of hysteresis.

  • Patent number: 8049851
    Abstract: A liquid crystal dripping method has a problem in that an uncured sealant increases in width at the time of attaching a pair of substrates and thus a liquid crystal material enters the sealant and unevenness occurs in the inner periphery of the sealant. A region in which reduced is the speed of diffusion of liquid crystal at the time of attaching a pair of substrates is provided between a sealant and an orientation film. Further, time for diffusing the liquid crystal and coming in contact with the sealant is made long. Accordingly, the sealant is subjected to photo-curing before the liquid crystal comes in contact with the sealant. The region in which reduced is the speed of diffusion of the liquid crystal is formed using a material for forming a vertical orientation film, a silane coupling agent, a substance having a photocatalytic function, or the like.

  • Patent number: 8049862
    Abstract: A layer of material, such as crystalline indium tin oxide (ITO), is formed on top of a substrate by heating the material to a high temperature, while a temperature increase of the substrate is limited such that the temperature of the substrate does not exceed a predetermined temperature. For example, a layer including amorphous ITO can be deposited on top of the substrate, and the amorphous layer can be heated in a surface anneal process using radiation while limiting substrate temperature. Another process can pass electrical current through the amorphous ITO. In another process, the substrate is passed through a high-temperature deposition chamber quickly, such that a portion of a layer of crystalline ITO is deposited, while the temperature increase of the substrate is limited.
