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 (119 worldwide citation)

Charged particles suspended in a medium such as Fluorinertâ„¢ 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: Passive high efficiency variable reflectivity image display device. The University of British Columbia, Oyen Wiggs Green & Mutala, September 28, 1999: US05959777 (96 worldwide citation)

A variably reflective display device amenable to multiple pixel display applications. Each pixel has at least one element having a reflective state in which incident light undergoes total internal reflection, and having a non-reflective state in which total internal reflection is prevented. Such pre ...
