摘要:
A method for making microencapsulated gyricon beads comprising the steps of converging a first, second, third and fourth materials in a liquid state; forming a bead from the first and second materials, the bead having two hemispheric surfaces with one surface differing from the other in optical and electrical characteristics; surrounding the bead with the third material; encapsulating the third material with the fourth material; and solidifying the fourth material.
