ABSTRACT:
A structured fluid composition comprising:(a) a low refractive index liquid;(b) particles 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).
