The display device further includes: a voltage controller configured to carry out grayscale value detection for a display data signal to be supplied to the display panel unit in every predetermined period, and create voltage control information of the signal amplitude reference voltage by using a detected grayscale value; and a signal amplitude reference voltage changer configured to change a voltage value of the signal amplitude reference voltage to be supplied to the pixel circuits of the display panel unit, based on voltage control information created by the voltage controller."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display device and display driving method including a voltage controller and a signal amplitude reference voltage changer","description":"A display device includes a display panel unit configured to include pixel circuits in each of which an organic electroluminescence device is used as a light emitting device and is driven to emit ligh","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8477088","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.
