The extension/degeneration circuit outputs a preprocessing signal increasing the input signal cycle length by 2 or outputs by degenerating the input signal to ½, based on a control signal, the demura circuit outputs a correction signal correcting the preprocessing signal from the extension/degeneration circuit, the separation/recovery circuit outputs a differential signal reducing the correction signal cycle length to ½ or reduces cycle length to ½ and outputs the same differential signal over two cycles, based on a control signal, the delay adjustment circuit outputs a delay signal delaying the input signal, and the adder circuit outputs a signal adding the differential signal to the delay signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Input signal correction device","description":"An input signal correction device for reducing power consumption is compatible with a variety of display panels, and includes an input circuit, extension/degeneration circuit, separation/recovery circ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11990104","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.
