The present invention relates to a display film that may be transferred by
lamination or otherwise onto a substrate. The display film is formed of a
stack of layers that can include different types, arrangements, and
functionality within the stack depending upon factors including the
characteristics of the substrate (e.g., upper or lower, transparent or
opaque, substrates) and addressing of the display (e.g., active or
passive matrix, electrical or optical addressing). The layers of the
stacked display film include one or more electrode layers and one or more
liquid crystal layers and, in addition, may include various combinations
of an adhesive layer, preparation layer, casting layer, light absorbing
layer, insulation layers, and protective layers. The liquid crystal layer
can include cholesteric or other liquid crystal material. The liquid
crystal layer can be a dispersion of liquid crystal in a polymer matrix
formed by a variety of techniques. The display film may interact with
components mounted on or laminated to the substrate, including a solar
cell, active matrix backplane and electrodes. The display film may be
mounted onto flexible or drapable substrates such as fabric and can
itself be drapable. A liquid crystal display includes the display film
and a single substrate for supporting the display film. Thus, the
invention offers substantial flexibility in fabrication and design that
has not been previously possible in the display industry.
