Liquid crystal display and driving method thereof

摘要

The present invention relates to a line inversion type liquid crystal display and a driving method thereof. A plurality of pixels arranged in a matrix, a plurality of data lines extending in a row direction and a plurality of gate lines extending in a column direction are disposed in a liquid crystal panel of the liquid crystal display. The pixel has a liquid crystal capacitor for performing display operation and a switching element turned on in response to a gate-on voltage to apply a data signal to the liquid crystal capacitor. A gate driver sequentially provides gate-on pulses to the gate lines based on gate control signals from a timing controller, and a data driver sequentially applies the data signals with polarity inversion, corresponding to color signals from the timing controller based on the data control signal from the timing controller. The polarity of the data signals is inverted by the unit of at least two pixel rows. Since the width of the gate-on pulse applied to the first pixel row with polarity inversion is larger than that of other gate-on pulses, a charging ratio of the first pixel row with polarity inversion is larger than that of the other rows.
