    摘要： We have found that liquid crystals can be aligned on a polyimide surface exposed to a low energy and neutral Argon ion beam. The energy of the incident ions were varied between 75 and 500 eV, the integrated current density from 100 .mu.A/cm.sup.2 to 500 mA/cm.sup.2, and the angle of incidence over which alignment was measured was between 10 and 20 degrees. The pretilt angle of the liquid crystals could be varied between 0 and 8 degrees, by controlling the processing conditions. Degradation of the polyimide, which leads to charge migration, can be avoided by operating at low accelerating voltages.

    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 method of generating a patterned alignment direction on an alignment surface for a liquid crystal display cell is described. The cell is formed by forming a first alignment direction on an alignment surface, such as a polyimide surface of the cell. A second alignment direction is formed on the alignment surface. The first and second alignment directions are formed by a variety of sequences of treatments. An example of a first sequence is a first step of rubbing the alignment surface and thereafter a second step of selectively exposing (preferably using a mask) the alignment surface to a treatment selected from the group of exposure to electromagnetic radiation and exposure to a particle beam. Another example of a sequence is a first step of exposing the alignment surface to a treatment selected from the group of electromagnetic radiation and a particle beam thereafter selectively exposing (preferably through a mask) the alignment surface to another particle beam.

    摘要： The present invention includes a method of preparing a dry deposited liquid-crystal alignment layer using one of a mechanical mask, photo-resist, UV treatment, and ridge and fringe field methods. The present invention further provides a multi-domain, wide viewing angle liquid-crystal display, comprising: a bottom substrate; a first transparent conductive layer; a top substrate; a color filter layer; a second transparent conductive layer; a first dry deposited liquid-crystal alignment layer; a second dry deposited liquid-crystal alignment layer, the second dry deposited liquid-crystal alignment layer being spaced adjacent to and facing the first dry deposited liquid-crystal alignment layer; spacers; and a liquid-crystal material. Each of the first alignment layer and the second alignment layer is divided into a plurality of pixels each having a boundary and at least two domains and the domains of each of the multi-domain, dry deposited liquid-crystal alignment layers is obtained by a method selected from the group consisting of: a mechanical mask, photo-resist, UV treatment, and ridge and fringe field. The multi-domain, wide viewing angle liquid-crystal display of the present invention can be operated in the in-plane switching mode, which results in reduced image sticking.

    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.
