The luminance data indicates a luminance value for each of light-emitting regions of the backlight based on a maximum gradation value among gradation values of image pixels of an input image that correspond to the light-emitting region. The special filter is applied such that, with respect to each light-emitting region, a difference of the luminance value thereof from the luminance values of neighboring light-emitting regions decreases, and the luminance setting data is generated therefrom. The gradation setting data sets a gradation value of each pixel of the liquid crystal panel, and is generated based on the input image and the luminance setting data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Luminance control of backlight in display of image","description":"An image display method includes generating luminance data, applying a special filter to the luminance data, generating luminance setting data, generating gradation setting data, and controlling a bac","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11972739","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.
