ABSTRACT:
An improved electrophoretic display device is provided including a first electrode, an opposed grid structure, and dielectric fluid having a plurality of inorganic pigment particles coated with an organosilane derivative movable between positions adjacent the electrodes during operation. The organosilane derivative preferably includes a quaternary ammonium moiety. The positively charged, pigment particles are rapidly released from the first, or viewing, electrode and are resistant to agglomeration.
