发明名称 Liquid crystal display and driving method therefor
摘要 A liquid crystal display apparatus includes a circuit for generating an alternating signal and a correction time-period signal, the alternating signal indicating alternating of an opposed electrode voltage applied to an opposed electrode, the correction time-period signal indicating a time period during which a correcting voltage is applied to the opposed electrode voltage applied to the opposed electrode, and an opposed electrode voltage generating circuit that, in accordance with the alternating signal and the correction time-period signal and with respect to the alternated opposed electrode voltage applied to the opposed electrode, adds an upwardly convex correcting voltage to the alternated opposed electrode voltage when the alternated opposed electrode voltage is a positive polarity voltage, and subtracts the upwardly convex correcting voltage from the alternated opposed electrode voltage when the alternated opposed electrode voltage is a negative polarity voltage.
