The present invention also discloses a system of correcting complexion color shift of LCD. The gamma value of front viewing angle of the LCD is increased. Accordingly, the gamma value of the image of big viewing angle approaches the curve of gamma value 2.2 more in the LCD and wash out of the complexion of the image of big viewing angle is eliminated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of correcting complexion color shift of LCD and a system thereof","description":"The present invention discloses a method of correcting complexion color shift of LCD including obtaining accounting ratio of a complexion region of an image which will be shown in the LCD; comparing t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9818371","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.
