In particular, the driving methods produce cleaner optical stakes of the lesser-charged particles with less contamination from the other particles and more consistent electro-optical performance when the intermediate driving voltages are modified."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods for achieving color states of lesser-charged particles in electrophoretic medium including at least four types of particles","description":"Methods for driving an electrophoretic medium including two pairs of oppositely charged particles.
