It is important to accurately align a pair of substrates, such as liquid crystal display (LCD) panels before they are affixed together. This is accomplished, according to the invention, by depositing a number of magnetic field generating elements on one substrate and a plurality of magnetic field-detecting elements on the other substrate. For example, the field-generating elements can be permanent magnets, while the field-detecting can be correspondingly located elements of a magnetic material. Alternatively, both the field-generating and field-detecting elements may be made from permanently magnetic materials.

Display panels and methods for fabrication are disclosed for an in-plane switching mode display to reduce or eliminate image sticking. The display panel includes a substrate with a first electrode formed on the substrate. A dielectric layer is formed on the substrate, and the dielectric layer forms an opening down to the first electrode so that the dielectric layer is eliminated over the first electrode. A second electrode is formed on the dielectric layer, and an alignment layer is formed on the first electrode, the second electrode and the dielectric layer.

A method for preparing an alignment layer surface provides a surface on the alignment layer. The surface is bombarded with ions, and reactive gas is introduced to the ion beam to saturate dangling bonds on the surface. Another method for preparing an alignment layer surface provides a surface on the alignment layer. The surface is bombarded with ions and quenched with a reactive component to saturate dangling bonds on the surface.

A liquid crystal display device includes an alignment layer with constituent materials. The constituent materials have a stoichiometric relationship configured to provide a given pretilt angle. Liquid crystal material is provided in contact with the alignment layer. A method for forming an alignment layer for liquid crystal displays includes forming the alignment layer on a substrate by introducing an amount of material to adjust a stoichiometric ratio of constituent materials wherein the amount is determined to provide a given pretilt angle to the alignment layer. Ions are directed at the alignment layer to provide uniformity of the pretilt angle.

Multi-domain liquid crystal cells having twist angles less than 90 degrees, and LCDs containing such liquid crystal cells, are provided. Such liquid crystal cells are stable, particularly at zero and high fields, and provide wide viewing angles. Also provided are methods of using an adjustable particle beam in combination with a mask to generate multi-domains alignments. Such methods are useful for producing liquid crystal cells in general, and for producing the novel multi-domain low twist angle liquid crystal cells of the present invention in particular.
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 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.
