Description

An electrophoretic display (EPID) based on the movement of particles in an insulating liquid is well known to be one of the technology utilized for the electric paper and has been actively investigated in the past few years. Emulsification and micro-encapsulation of dispersion containing with white and black particles dispersed in an insulating liquid is reported in this paper. The gelatin and melamine resin was used for surfactant and wall material of micro-capsule, respectively. The optimization of the preparation condition of the micro-encapsulation was done. The EPID using the micro-encapsulated electrophoretic ink displays black and white solid image in the response to an external voltage.
