The OLED, pixel circuit, and driver may be controlled by signals in a frame that includes first through fourth periods, the second power supply may be set to a first voltage in the first and second periods and to a second voltage in the third and fourth periods, and the first voltage may be a voltage at which the OLED does not emit light and the second voltage may be a voltage at which the OLED emits light."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pixel and organic light emitting display device using the same","description":"A pixel includes an organic light emitting diode (OLED) having a cathode electrode coupled to a second power supply, a pixel circuit configured to control an amount of current supplied to the OLED to ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9601056","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.
