Method of and apparatus for driving liquid-crystal display device
摘要
A liquid-crystal display device of a simple matrix type is permitted to present a liquid-crystal display of good display quality free from nonuniformity in display brightness. A method of driving a liquid-crystal display device wherein voltages which correspond to potential differences between scanning voltages from a Y drive circuit and display voltages from an X drive circuit are applied to liquid-crystal cells at intersection points between scanning electrodes (Y electrodes) and data electrodes (X electrodes), thereby presenting a display conforming to display data comprises the steps of providing a correction time period for correcting the display voltage to be output from the X drive circuit at least once every scanning period of one line, and outputting a correction voltage at a voltage level which is intermediate between a voltage level in an ON-display state and a voltage level in an OFF-display state instead of the display voltage from the X drive circuit within the correction time period.
