If the liquid crystal display device shifts to an off-sequence mode, then a data signal Vd with a potential Vdoff1 corresponding to a shift amount ΔV3 lowered by a coupling effect of a parasitic capacitance formed between a gate terminal and drain terminal of a thin film transistor (12) is applied to a signal line SL. When a scanning signal Vg turns to a high level, the data signal Vd applied to the signal line SL is written into the pixel formation portion (11), and a potential of a pixel signal Vpix becomes the Vdoff1. When the scanning signal Vg falls to a ground potential GND after an elapse of a period t1, the potential of the pixel signal Vpix is lowered by a shift amount ΔV3, and accordingly, the potential of the pixel signal Vpix becomes the ground potential GND. In this way, a direct current voltage applied to the liquid crystal layer also becomes 0V."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid crystal display device and driving method thereof","description":"Provided are: a liquid crystal display device capable of rapidly discharging an image signal which is held in a pixel formation portion, when a power supply thereof is turned off; and a driving method","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9595232","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.
