A luminance compensation value of the unit light-emitting block may be calculated by compensating the luminance representative value. Pixel data of the external image signal in a central area of the unit light-emitting block and a boundary area may be corrected based on the luminance compensation value. A driving signal may be provided to the unit light-emitting block based on the luminance compensation value. Accordingly, a phenomenon in which a boundary of the unit light-emitting block is visible is removed so that the display quality of all image may be enhanced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of driving a display apparatus to compensate for uneven backlighting","description":"A method for driving a display apparatus, according to one or more embodiments of the present invention, provides a luminance representative value of a unit light-emitting block that may be determined","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8482509","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.
