The fluid holder comprises a fluid reservoir and a channel. The channel is connected to the reservoir so as to enable movement of the polar fluid and non-polar fluid between the channel and the reservoir. A supply voltage applied to the channel results in a movement of the polar fluid to change a cell display property. A circuit board supplies an electrical charge to the pixel cells to generate the supply voltage. A display controller comprises a state lookup table storing, for a respective pixel cell, the current pixel cell display property. The display controller calculates the electrical charge as a function of the current pixel cell display property and the new pixel cell display property."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display apparatus comprising electrofluidic cells driven based on calculated charge corresponding to current and new pixel cell display properties","description":"A display apparatus is disclosed comprising a plurality of electrofluidic chromatophore (EFC) pixel cells, each pixel cell comprising a fluid holder for holding a polar fluid and a non-polar fluid hav","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8508468","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
