Title (EN) ELECTROPHORETIC MEDIUM WITH GASEOUS SUSPENDING FLUID
(FR) MILIEU ELECTROPHORETIQUE A FLUIDE DE SUSPENSION GAZEUX
Abstract:
(EN) An electrophoretic medium (102) comprises a plurality of capsules (104), each capsule comprising an internal phase comprising a plurality of electrophoretically mobile particles (108) in a gaseous suspending medium, and a capsule wall surrounding the internal phase. Various processes for producing such an electrophoretic medium are also described.
(FR) La présente invention concerne un milieu électrophorétique (102) comprenant une pluralité de capsules (104). Chaque capsule renferme une phase intérieure comprenant une pluralité de particules mobiles par électrophorèse (108) dans un milieu de suspension gazeux, une paroi de capsule entourant la phase intérieure. L'invention concerne également divers procédés de production d'un tel milieu électrophorétique.
