The first common voltage regulator regulates a common voltage to minimize a flicker during a switching mode between a white frame and a black frame and set this common voltage as a first common voltage. The second common voltage regulator regulates a common voltage to minimize a flicker during a switching mode between a gray frame and a black frame and set this common voltage as a second common voltage. The sequential controller inserts predetermined number of abnormal frames every predetermined number of normal frames according to a preset scan frequency. The switching circuit is correspondingly connected to the first common voltage regulator and a second common voltage regulator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Residual image removing method and liquid crystal display using same","description":"The present invention discloses a liquid crystal display including a first common voltage regulator, a second common voltage regulator, a switching circuit, and a sequential controller.
