摘要： The present invention is a method for forming a liquid-crystal cell of a liquid-crystal display. Initially, a dry processed alignment film is deposited onto a first transparent substrate using a dry processing technique, such as plasma enhanced chemical vapor deposition (PECVD). The dry processed alignment film is then irradiated with a beam of atoms to arrange the atomic structure of the alignment film in at least one desired direction in order to orient the liquid-crystal molecules. Another dry processed alignment film is deposited on a second substrate using a dry processing technique and, likewise, irradiated with a beam of atoms. The first transparent substrate and the second substrate are then sandwiched together with their respective alignment films spaced adjacent to each other. The space between the films is then filled with a liquid-crystal material.

摘要： A method is disclosed for forming an alignment layer for use in a liquid crystal cell layer for use in a liquid crystal cell using an ion beam source that includes the steps of: (1) providing a substrate having a surface; (2) providing an ion beam source that emanates an ion beam; (3) providing a mask layer disposed between the substrate surface and the ion beam source. The mask layer has at least two openings disposed between the ion beam source and the substrate surface. The shape and position of the openings reduce the irregularity of the beam exposure in a border region on the surface of the substrate resulting from the ion beam source. The present invention may be used in conjunction with substrate treatment using multiple sweeps with a single ion beam source, or with a substrate treatment using a single sweep with multiple ion beam sources. Also disclosed is an apparatus for practicing the disclosed method.

摘要： A liquid crystal display device includes a first substrate, a dry alignment film deposited over the substrate, a second substrate coupled to the first substrate with the dry alignment film deposited over the second substrate therebetween and forming a cell gap, and a liquid crystal material formed in the cell gap. The dry alignment film allows for a truly vertical alignment of molecules of the liquid crystal material such that the molecules form an angle of substantially 90° relative to the substrate. The dry alignment film can be an oxide layer, a nitride layer, an oxynitride layer or a silicon layer. This dry alignment layer can be treated to form a tilted homeotropic alignment, such that the liquid crystal molecules have a pretilt angle of 0.5 to 10 degrees from a substrate normal direction. The truly vertical alignment process can be incorporated with a ridge and fringe field process method to form a multidomain Vertical Alignment (VA) Liquid Crystal Display's (LCDs) which have wide viewing angles.

摘要： A self-alignment process for the precise alignment in a deposited diamond-like carbon (DLC), which results in a wider viewing angle for the display being manufactured. The process involves ion bombardment, which is swept across the liquid crystal panel in a two-pass process. In one embodiment, both ion sweeps are aligned at a 45-degree angle with respect to the bottom edge of the panel. The first pass is accomplished without any electrical bias on the panel. During the first pass the impinging ions may be at an angle with respect to a point on a plane defined by the surface of the panel that is less than 90 degrees. The second ion sweep is accomplished with the impinging ions at a second angle, greater than 90 degrees up to 180 degrees with respect to the point on the plane defined by the surface.
