Liquid crystal driving device

摘要

A liquid crystal driving device is provided which enables an overshooting driving operation in transition among all gray levels. When a voltage for displaying is controlled so as to be a highest-level value out of the voltages for displaying corresponding to an input gray level range, an overshooting driving voltage for transition to a higher voltage which is added to a voltage side being higher than the highest-value value out of the voltages for displaying is applied to a liquid crystal panel and, when a voltage for displaying to be applied to the liquid crystal panel is controlled so as to be a lowest-level value out of the voltages for displaying corresponding to the input gray level range, an overshooting driving voltage for transition to a lower voltage which is added to a voltage side being lower than the lowest-level value of the voltages for displaying is applied to the liquid crystal panel.
