In a first mode that the first voltage is set as the middle power supply voltage, the first output stage outputs a first drive voltage in the first voltage range to one of first and second output terminals. In a second mode that the first voltage is set as the ground voltage, the second output stage outputs a first drive voltage in the first voltage range to one of the first and second output terminals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display panel driver and display apparatus using the same","description":"In a display panel driver an output amplifier circuit includes a first output stage to receive a power supply voltage and a first voltage lower thereto and to output a drive voltage in a first voltage","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8487921","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.
