The second circuit unit calculates a saturation feature value in one frame from the saturation value of each pixel, generates a signal for controlling the luminance of the backlight based thereupon, and calculates a luminance increase rate by using the saturation value of each pixel and the saturation feature value. The first circuit unit performs luminance decreasing processing of each pixel according to the luminance increase rate, and supplements the saturation of each pixel according to the light-up amount of the white sub-pixels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control signal generation circuit and control signal generation method for controlling luminance in a display device","description":"A control signal generation circuit includes: a first circuit unit which controls, according to inputted video signals, light-up amount of each pixel of a display panel where a plurality of pixels con","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9711112","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.
