The driving current includes a first AC period and a second AC period in which an AC current is supplied. The first AC period includes a plurality of consecutive first unit driving periods each of which is formed of a first polarity period and a second polarity period, a length of the first polarity period being larger than a length of the second polarity period. The second AC period includes a plurality of consecutive second unit driving periods each of which is formed of the first polarity period and the second polarity period, the length of the second polarity period being larger than the length of the first polarity period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Discharge lamp driving device, projector, and discharge lamp driving method","description":"A discharge lamp driving device includes a discharge lamp driving unit configured to supply driving current to a discharge lamp provided with a first electrode and a second electrode, and a controller","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9602791","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.
