The driving methods improve the color state performance when a first pixel is displaying a mixed state of a first highly-charged particle and a second lower-charged particle of the opposite polarity, while a neighboring pixel is displaying a state of a second highly-charged particle having the opposite polarity to the first highly-charged particle. The particles can be, for example, all reflective or one type of particle can be partially light transmissive."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Four-particle electrophoretic displays with synchronized driving waveforms","description":"The present invention provides four-particle electrophoretic displays with improved driving methods to achieve better color separation between adjacent pixel electrodes.
