Lorne A Whitehead, Dmitri Nikolaevich Grandmaison, Robin John Noel Coope, Michele Ann Mossman, Andrzej Kotlicki: Electrophoretic, high index and phase transition control of total internal reflection in high efficiency variable reflectivity image displays. The University of British Columbia, Oyen Wiggs Green & Mutala, April 10, 2001: US06215920 (127 worldwide citation)

Charged particles suspended in a medium such as Fluorinert™ Electronic Liquid are used to electrophoretically control total internal reflection (TIR) at a retro-reflective surface formed on a high refractive index material. Prismatic structures redirect ambient light from an overhead light source to ...

Lorne A Whitehead, Michele Ann Mossman: Brightness enhancement film for backlit image displays. The University of British Columbia, Oyen Wiggs Green & Mutala, October 23, 2007: US07286280 (110 worldwide citation)

A brightness enhancement film having a monolayer of approximately hemispherical, transparent, closely packed larger diameter hemi-beads. Due to the hemi-beads' hemispherical shape, gaps remain between adjacent ones of the larger diameter hemi-beads. A substantial number of the gaps are provided with ...

Lorne A Whitehead, Dmitri Nikolaevich Grandmaison, Robin John Noel Coope, Michele Ann Mossman: Electrophoretic, dual refraction frustration of total internal reflection in high efficiency variable reflectivity image displays. The University of British Columbia, Oyen Wiggs Green & Mutala, May 16, 2000: US06064784 (70 worldwide citation)

A display device and method in which electrophoresis and/or dual prismatic surfaces are used to controllably frustrate total internal reflection at an interface between materials having different refractive indices. In one embodiment, an array of solid dielectric light fibers is surrounded by an ele ...

Lorne A Whitehead, Michele Ann Mossman: Color filtering and absorbing total internal reflection image display. The University of British Columbia, Oyen Wiggs Green & Mutala, May 7, 2002: US06384979 (42 worldwide citation)

A color image display having a spatially uniform distribution of at least two different “types” of prism structure. The first type consists of a prism, a color filter associated with one of the prism's facets and two color absorbing control members, each of which can be biased away from or into ...

Lorne A Whitehead, Michele Ann Mossman: Composite electrophoretically-switchable retro-reflective image display. The University of British Columbia, Oyen Wiggs Green & Mutala, September 17, 2002: US06452734 (41 worldwide citation)

A light deflector/recombiner is longitudinally symmetrical with respect to an X axis perpendicular to a Z axis. An X and Z vector components inverter longitudinally symmetrical with respect to both the X axis and a Y axis perpendicular to the X and Z axes lies parallel to the deflector/recombiner. A ...

Lorne A Whitehead, Michele Ann Mossman: Self-stabilized electrophoretically frustrated total internal reflection display. The University of British Columbia, Oyen Wiggs Green & Mutala, March 8, 2005: US06865011 (19 worldwide citation)

An image display has a transparent front sheet with a prismatically microstructured inward surface and a rear sheet substantially parallel to and spaced from the front sheet. An electrophoretic suspension fills the space between the sheets. The suspension is formed by suspending non-light-scattering ...
