The machine has memory in which both primary text and secondary text are stored. As the user of the machine changes the page of primary text displayed on the leftmost screen display, ebook controller circuitry automatically refreshes the rightmost screen display to allow the user to cross reference between the primary textual material and the secondary textual material, or at his or her discretion to change the page of secondary textual material displayed, thereby fine tuning the juxtaposition of pages for study."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic book reader with closely juxtaposed display screens","description":"A portable electronic book reading machine has two display screens juxtaposed in close proximity to allow for automatic cross referencing between primary textual material displayed on the leftmost dis","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9851747","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.
