US Classification:

349117, 427164, 427508

Abstract:

A process for making an optical compensator, comprising the steps of coating a orientable resin in a solvent onto a support; drying the resin-containing coating; orienting the resin-containing layer in a predetermined direction; coating a nematic liquid-crystal compound in a solvent carrier onto the orientation layer; drying the nematic liquid-crystal-containing coating; thermally treating the nematic liquid-crystal compound layer, cooling the nematic liquid-crystal compound layer, polymerizing or curing the anisotropic nematic liquid-crystalline layer to form an integral component; and optionally repeating the above steps on top of the integral component so that the optical axis of the first anisotropic nematic liquid-crystal layer is positioned orthogonally relative to the respective optical axis of the second anisotropic nematic liquid-crystal layer about an axis perpendicular to the plane of the support.

International Classification:

H01L 21/20

US Classification:

438584, 347 77, 257E21001

Abstract:

Methods and apparatuses are provided for depositing a material on a surface. In accordance with the method a stream of a component material is formed having formed printing and non-printing droplets and satellite droplets of the material. The stream is directed at the surface. A deflecting energy is applied to separate printing droplets from non-printing droplets in the stream, so that only printing droplets travel to the surface. The deflecting energy is adapted to direct non-printing droplets for non-printing drop collection, and to direct at least a portion of the satellite droplets to be controlled in a manner adapted to prevent the material in the satellite droplets from reaching the surface, so that less than all of the material in the satellite droplets reaches the surface. Articles are also provided having limited satellite material.

International Classification:

G02F001/1335

US Classification:

349/117000

Abstract:

Disclosed is an optical compensator and process for liquid crystal displays comprising a transparent polymeric support, an orientation layer, and an optically anisotropic layer, in order, wherein the anisotropic layer contains a surfactant. The uniformity and quality of this film is enhanced by the use of a surfactant in the optical anisotropic layer.

International Classification:

G02F001/1335

US Classification:

349/117000

Abstract:

Disclosed is an optical compensator film for a liquid crystal display and a process for forming the film comprising the steps of (1) coating an anisotropic layer containing liquid crystal prepolymer materials and an organic solvent system that is both miscible with said materials and has a weight average boiling point of from 85 to 130 C. and subsequently (2) drying the layer. The compensator widens the viewing angle characteristics of liquid crystal displays and is readily manufactured with improved quality and uniformity of coated layers.

Abstract:

Disclosed optical compensator for a liquid crystal display comprising a transparent polymeric support, an orientation layer, and an optically anisotropic layer comprising a nematic liquid crystal, in order, wherein the anisotropic layer contains a colorless polymer having a weight average molecular weight that is greater that the entanglement molecular weight of the polymer. The uniformity and quality of this film is enhanced by the addition of a high molecular weight polymer.
