The device has a voltage controller configured to apply a first and a smaller second potential difference, of either polarity, between the electrodes. The electrophoretic medium has first, second, and third species of particles of differing colors and charge polarities. The first and second particles move independently of one another in response to the first potential difference, but upon application of the second potential difference form charged aggregates, moving as a unit, having an aggregate color different from the first and second colors."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Aggregate particles for use in electrophoretic color displays","description":"A multi-color display device has front and rear electrodes on opposed sides of an electrophoretic medium.
