After writing the video signal to all the pixels in each sub-frame period, a correction voltage signal or an alternating signal having a frequency of greater than or equal to a certain frequency is input to the data line, so that the magnitude of the leakage current of each pixel TFT caused by the difference in polarity of the video signal with respect to the opposing electrode written to the pixel electrode is equalized, and the flickers are greatly reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid crystal display device with correction voltage different from video signal applied to data line in display period","description":"The present invention aims to reduce flickers of the liquid crystal display device and enable the use of liquid crystal material exhibiting a high response speed, and to enhance light usage efficiency","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493302","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.
