Filed:

Oct 9, 2001

Appl. No.:

09/973243

Inventors:

Asad A. Khan - Kent OH
Xiao-Yang Huang - Stow OH
J. William Doane - Kent OH

Donald J. Davis - Conneaut Lake PA

Assignee:

Kent Displays, Inc. - Kent OH

International Classification:

G02F 11375

US Classification:

349115, 349169

Abstract:

The present invention is directed to a cholesteric liquid crystal display that includes a homogeneous alignment surface effective to provide increased brightness, low focal conic reflectance and/or reflected light that is to a significant degree circularly polarized. The homogeneous alignment surface substantially homogeneously aligns the liquid crystal director adjacent thereto. The homogeneous alignment surface may be disposed on one or both sides of a cell of the display. In the case of a cell in which the homogeneous alignment surface is disposed on only one side, the substrate with the inhomogeneous alignment surface may be upstream or downstream of the substrate with the homogeneous alignment surface relative to a direction of incident light. Also included especially in the case of a cell that has the homogeneous alignment surface on both sides is the use of a polarizer to provide very good brightness and low focal conic reflectance. Such a cell may employ an alignment layer material with a high pretilt angle.

International Classification:

B32B 3104

US Classification:

156230

Abstract:

In a method of transporting vehicle windows and sealant, the sealant is preferably inserted into a sealant groove formed in a carrier. The carrier thus forms both a mold for forming the sealant and a transport device. The sealant groove includes a release agent such that the sealant easily leaves the groove. The carriers have structure such that they may be stacked in a first orientation wherein a relatively great spacing is provided between the carriers. The carriers are stacked in this orientation when a window and/or sealant is received on the carriers. After the windows and sealant have been removed from the carriers, the carriers are restacked in a second orientation wherein the distance between adjacent stacked carriers is substantially smaller. This orientation is used when the carriers are returned for re-use.
