Abstract

Disclosed is an imaging system wherein there is provided an imaging suspension of photoelectrophoretic imaging particles in an insulating carrier liquid. There is added to this imaging suspension comprising light sensitive particles in a carrier liquid, a substantially colorless or transparent particle thereby improving the quality and permanency of the resulting image. This imaging suspension is placed in an electroded system, exposed selectively to an electromagnetic radiation source while applying voltage across the imaging suspension. Particle migration takes place within the system, resulting in a visible image at one or both of the electrodes.

Disclosed is an imaging system wherein there is provided an
imaging suspension of photoelectrophoretic imaging particles
in an insulating carrier liquid. There is added to this
imaging suspension comprising light sensitive particles in a
carrier liquid, a substantially colorless or transparent
particle thereby improving the quality and permanency of the
resulting image. This imaging suspension is placed in an
electroded system, exposed selectively to an electromagnetic
radiation source while applying voltage across the imaging
suspension. Particle migration takes place within the system,
resulting in a visible image at one or both of the electrodes.

The transparent particle is generally a solid, substantially
colorless or transparent organic or inorganic material, such
as zinc oxide, silica dioxide, anthracene, or polyvinyl
chloride.
