| A light controlling film is disclosed, comprising a polymerized polymer network varying spatially in a direction normal to the film surface, where the polymerized polymer network is a crosslinked high molecular weight polymeric material mixed with a low molecular weight nematic material exhibiting cholesteric liquid crystal (CLC) order, wherein an electric field impressed in the film controls the reflection bandwidth of circularly polarized light. | ||||||

| Cholesteric liquid crystal films using varying pitch helix structures aligned perpendicular to the surface of the film for broadband reflection and transmission of circularly polarized light distort the light at large viewing angles of incidence due to the elliptical cross section of the CLC helix with the light at large incident angles. By using compensating films of an infrared cholesteric liquid crystal to rotate the major axis of the elliptical light to ±45 degrees and a homeotropic film having elongated molecules with the long axis perpendicular to the surface of the film to convert the elliptically adjusted light from the IR CLC film to circularly polarized light, the distortions at large angles can be eliminated. The compensated light will be circularly polarized for large angles of incidence over a broad band. | ||||||

| 118 | Method and system for producing color images with improved brightness and color characteristics on radiation absorptive surfaces | US08898658 | 1997-07-22 | US06404464B1 | 2002-06-11 | Sadeg M. Faris; Le Li |
| Disclosed is an improved method and apparatus for forming color images on radiation absorptive surfaces, having improved brightness and color characteristics. The apparatus can be realized in various forms, including Xeroxgraphic and ink-jet printing equipment. In the illustrative embodiments, color images composed from polarization-encoded perspective images are produced for use in stereoscopic viewing full-color 3-D objects represented therein using a pair of electrically-passive circularly-polarizing eyeglasses. Super-white and additive-primary coloring media is used to form the polarization-encoded composite images so that full depth of color (e.g. thousands of color values) is imparted to the 3-D objects graphically represented therein. The coloring media utilized embodies both broadband and spectrally-tuned CLC-based microflakes having symmetrical reflection characteristics which provide for improved brightness and color uniformity characteristics. | ||||||

| Disclosed are novel reflective films having symmetrical reflection characteristics on the upper and lower surfaces thereof. Preferably, such films are made from cholesteric liquid crystal (CLC) material, wherein the pitch of the helices of the liquid crystal molecules therein varies along the thickness dimension (i.e. transverse to the surface) of the film. Depending on the final spiral structure of the materials utilized, the CLC circularly polarizing film materials reflect either left-handed or right-handed circularly polarized light. In a first illustrative embodiment, the CLC film has a laminated construction in order that both the upper and lower surfaces thereof have substantially the same reflection characteristics over its tuned reflection band. In second illustrative embodiment, the CLC film has a laminated construction in order that both the upper and lower surfaces thereof have substantially the same reflection characteristics over its broadband reflection band. By virtue of their circularly polarizing reflection characteristics, the CLC films of the present invention can be used to form polarization-encoded spatially multiplexed images (SMI) on radiation absorbing surfaces, coloring media with high brightness characteristics, CLC-based toner 2-D and 3-D xerographic printing processes, and the like. | ||||||
