Title:
STRUCTURED FLUID COMPOSITIONS FOR ELECTROPHORETICALLY FRUSTRATED TOTAL INTERNAL REFLECTION DISPLAYS
Document Type and Number:
WIPO Patent Application WO2005073787
Kind Code:
A3
Abstract:
A structured fluid composition comprising: (a) a low refractive index liquid (104); (b) particles (100) including light absorbing charged particles such as pigments, non-light absorbing uncharged particles such as teflon, silica, alumina and combinations thereof; and (c) at least one additive selected from the group consisting of a dispersant, a charging agent, a surfactant, a flocculating agent, a polymer, and combination thereof; for use in a TIR electronic display. The inventive composition improves the long-term stability, response time and visible appearance of image displays which electrophoretically frustrate total internal reflection (TIR).
