Electrophoretic display

摘要

An electrophoretic display comprises a pixel which has a pixel volume comprising a reservoir volume and an image volume. Particles which have different colors and different electrophoretic mobilities are present in the pixel volume. An amount of the particles present in the image volume determines a visible color of the pixel. Select electrodes generate in the reservoir volume a select electric field which separates the particles in different sub-volumes in the reservoir volume. Fill electrodes generate a fill electric field to move the particles from the different sub-volumes into the image volume.
